COMMANDS
Repository creation
clone
make a copy of an existing repository:
hg clone [OPTION]... SOURCE [DEST]
Create a copy of an existing repository in a new directory.
If no destination directory name is specified, it defaults to the basename of the source.
The location of the source is added to the new repository's .hg/hgrc file, as the default
to be used for future pulls.
Only local paths and ssh:// URLs are supported as destinations. For ssh:// destinations,
no working directory or .hg/hgrc will be created on the remote side.
If the source repository has a bookmark called '@' set, that revision will be checked out
in the new repository by default.
To check out a particular version, use -u/--update, or -U/--noupdate to create a clone
with no working directory.
To pull only a subset of changesets, specify one or more revisions identifiers with
-r/--rev or branches with -b/--branch. The resulting clone will contain only the specified
changesets and their ancestors. These options (or 'clone src#rev dest') imply --pull, even
for local source repositories.
In normal clone mode, the remote normalizes repository data into a common exchange format
and the receiving end translates this data into its local storage format. --stream acti-
vates a different clone mode that essentially copies repository files from the remote with
minimal data processing. This significantly reduces the CPU cost of a clone both remotely
and locally. However, it often increases the transferred data size by 30-40%. This can
result in substantially faster clones where I/O throughput is plentiful, especially for
larger repositories. A side-effect of --stream clones is that storage settings and re-
quirements on the remote are applied locally: a modern client may inherit legacy or inef-
ficient storage used by the remote or a legacy Mercurial client may not be able to clone
from a modern Mercurial remote.
Note Specifying a tag will include the tagged changeset but not the changeset containing
the tag.
For efficiency, hardlinks are used for cloning whenever the source and destination are on
the same filesystem (note this applies only to the repository data, not to the working di-
rectory). Some filesystems, such as AFS, implement hardlinking incorrectly, but do not re-
port errors. In these cases, use the --pull option to avoid hardlinking.
Mercurial will update the working directory to the first applicable revision from this
list:
a. null if -U or the source repository has no changesets
b. if -u . and the source repository is local, the first parent of the source repository's
working directory
c. the changeset specified with -u (if a branch name, this means the latest head of that
branch)
d. the changeset specified with -r
e. the tipmost head specified with -b
f. the tipmost head specified with the url#branch source syntax
g. the revision marked with the '@' bookmark, if present
h. the tipmost head of the default branch
i. tip
When cloning from servers that support it, Mercurial may fetch pre-generated data from a
server-advertised URL or inline from the same stream. When this is done, hooks operating
on incoming changesets and changegroups may fire more than once, once for each pre-gener-
ated bundle and as well as for any additional remaining data. In addition, if an error oc-
curs, the repository may be rolled back to a partial clone. This behavior may change in
future releases. See hg help -e clonebundles for more.
Examples:
o clone a remote repository to a new directory named hg/:
hg clone https://www.mercurial-scm.org/repo/hg/
o create a lightweight local clone:
hg clone project/ project-feature/
o clone from an absolute path on an ssh server (note double-slash):
hg clone ssh://user@server//home/projects/alpha/
o do a streaming clone while checking out a specified version:
hg clone --stream http://server/repo -u 1.5
o create a repository without changesets after a particular revision:
hg clone -r 04e544 experimental/ good/
o clone (and track) a particular named branch:
hg clone https://www.mercurial-scm.org/repo/hg/#stable
See hg help urls for details on specifying URLs.
Returns 0 on success.
Options:
-U, --noupdate
the clone will include an empty working directory (only a repository)
-u,--updaterev <REV>
revision, tag, or branch to check out
-r,--rev <REV[+]>
do not clone everything, but include this changeset and its ancestors
-b,--branch <BRANCH[+]>
do not clone everything, but include this branch's changesets and their ancestors
--pull use pull protocol to copy metadata
--uncompressed
an alias to --stream (DEPRECATED)
--stream
clone with minimal data processing
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
[+] marked option can be specified multiple times
init
create a new repository in the given directory:
hg init [-e CMD] [--remotecmd CMD] [DEST]
Initialize a new repository in the given directory. If the given directory does not exist,
it will be created.
If no directory is given, the current directory is used.
It is possible to specify an ssh:// URL as the destination. See hg help urls for more in-
formation.
Returns 0 on success.
Options:
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
Remote repository management
incoming
show new changesets found in source:
hg incoming [-p] [-n] [-M] [-f] [-r REV]... [--bundle FILENAME] [SOURCE]
Show new changesets found in the specified path/URL or the default pull location. These
are the changesets that would have been pulled by hg pull at the time you issued this com-
mand.
See pull for valid source format details.
With -B/--bookmarks, the result of bookmark comparison between local and remote reposito-
ries is displayed. With -v/--verbose, status is also displayed for each bookmark like be-
low:
BM1 01234567890a added
BM2 1234567890ab advanced
BM3 234567890abc diverged
BM4 34567890abcd changed
The action taken locally when pulling depends on the status of each bookmark:
added
pull will create it
advanced
pull will update it
diverged
pull will create a divergent bookmark
changed
result depends on remote changesets
From the point of view of pulling behavior, bookmark existing only in the remote reposi-
tory are treated as added, even if it is in fact locally deleted.
For remote repository, using --bundle avoids downloading the changesets twice if the in-
coming is followed by a pull.
Examples:
o show incoming changes with patches and full description:
hg incoming -vp
o show incoming changes excluding merges, store a bundle:
hg in -vpM --bundle incoming.hg
hg pull incoming.hg
o briefly list changes inside a bundle:
hg in changes.hg -T "{desc|firstline}\n"
Returns 0 if there are incoming changes, 1 otherwise.
Options:
-f, --force
run even if remote repository is unrelated
-n, --newest-first
show newest record first
--bundle <FILE>

recurse into subrepositories
[+] marked option can be specified multiple times
aliases: in
outgoing
show changesets not found in the destination:
hg outgoing [-M] [-p] [-n] [-f] [-r REV]... [DEST]...
Show changesets not found in the specified destination repository or the default push lo-
cation. These are the changesets that would be pushed if a push was requested.
See pull for details of valid destination formats.
With -B/--bookmarks, the result of bookmark comparison between local and remote reposito-
ries is displayed. With -v/--verbose, status is also displayed for each bookmark like be-
low:
BM1 01234567890a added
BM2 deleted
BM3 234567890abc advanced
BM4 34567890abcd diverged
BM5 4567890abcde changed
The action taken when pushing depends on the status of each bookmark:
added
push with -B will create it
deleted
push with -B will delete it
advanced
push will update it
diverged
push with -B will update it
changed
push with -B will update it
From the point of view of pushing behavior, bookmarks existing only in the remote reposi-
tory are treated as deleted, even if it is in fact added remotely.
Returns 0 if there are outgoing changes, 1 otherwise.
Options:
-f, --force
run even when the destination is unrelated
-r,--rev <REV[+]>
a changeset intended to be included in the destination
-n, --newest-first

--insecure
do not verify server certificate (ignoring web.cacerts config)
-S, --subrepos
recurse into subrepositories
[+] marked option can be specified multiple times
aliases: out
paths
show aliases for remote repositories:
hg paths [NAME]
Show definition of symbolic path name NAME. If no name is given, show definition of all
available names.
Option -q/--quiet suppresses all output when searching for NAME and shows only the path
names when listing all definitions.
Path names are defined in the [paths] section of your configuration file and in /etc/mer-
curial/hgrc. If run inside a repository, .hg/hgrc is used, too.
The path names default and default-push have a special meaning. When performing a push or
pull operation, they are used as fallbacks if no location is specified on the com-
mand-line. When default-push is set, it will be used for push and default will be used
for pull; otherwise default is used as the fallback for both. When cloning a repository,
the clone source is written as default in .hg/hgrc.
Note default and default-push apply to all inbound (e.g. hg incoming) and outbound
(e.g. hg outgoing, hg email and hg bundle) operations.
See hg help urls for more information.
Template:
The following keywords are supported. See also hg help templates.
name String. Symbolic name of the path alias.
pushurl
String. URL for push operations.
url String. URL or directory path for the other operations.
Returns 0 on success.
Options:
-T,--template <TEMPLATE>
display with template
pull
pull changes from the specified source:
hg pull [-u] [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [SOURCE]...
Pull changes from a remote repository to a local one.
This finds all changes from the repository at the specified path or URL and adds them to a
local repository (the current one unless -R is specified). By default, this does not up-
date the copy of the project in the working directory.
When cloning from servers that support it, Mercurial may fetch pre-generated data. When
this is done, hooks operating on incoming changesets and changegroups may fire more than
once, once for each pre-generated bundle and as well as for any additional remaining data.
See hg help -e clonebundles for more.
Use hg incoming if you want to see what would have been added by a pull at the time you
issued this command. If you then decide to add those changes to the repository, you should
use hg pull -r X where X is the last changeset listed by hg incoming.
If SOURCE is omitted, the 'default' path will be used. See hg help urls for more informa-
tion.
If multiple sources are specified, they will be pulled sequentially as if the command was
run multiple time. If --update is specify and the command will stop at the first failed
--update.
Specifying bookmark as . is equivalent to specifying the active bookmark's name.
Returns 0 on success, 1 if an update had unresolved files.
Options:
-u, --update
update to new branch head if new descendants were pulled
-f, --force
run even when remote repository is unrelated
--confirm
confirm pull before applying changes
-r,--rev <REV[+]>
a remote changeset intended to be added
-B,--bookmark <BOOKMARK[+]>
bookmark to pull
-b,--branch <BRANCH[+]>
a specific branch you would like to pull
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
[+] marked option can be specified multiple times
push
push changes to the specified destination:
hg push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]...
Push changesets from the local repository to the specified destination.
This operation is symmetrical to pull: it is identical to a pull in the destination repos-
itory from the current one.
By default, push will not allow creation of new heads at the destination, since multiple
heads would make it unclear which head to use. In this situation, it is recommended to
pull and merge before pushing.
Use --new-branch if you want to allow push to create a new named branch that is not
present at the destination. This allows you to only create a new branch without forcing
other changes.
Note Extra care should be taken with the -f/--force option, which will push all new
heads on all branches, an action which will almost always cause confusion for col-
laborators.
If -r/--rev is used, the specified revision and all its ancestors will be pushed to the
remote repository.
If -B/--bookmark is used, the specified bookmarked revision, its ancestors, and the book-
mark will be pushed to the remote repository. Specifying . is equivalent to specifying the
active bookmark's name. Use the --all-bookmarks option for pushing all current bookmarks.
Please see hg help urls for important details about ssh:// URLs. If DESTINATION is omit-
ted, a default path will be used.
When passed multiple destinations, push will process them one after the other, but stop
should an error occur.
The --pushvars option sends strings to the server that become environment variables
prepended with HG_USERVAR_. For example, --pushvars ENABLE_FEATURE=true, provides the
server side hooks with HG_USERVAR_ENABLE_FEATURE=true as part of their environment.
pushvars can provide for user-overridable hooks as well as set debug levels. One example
is having a hook that blocks commits containing conflict markers, but enables the user to
override the hook if the file is using conflict markers for testing purposes or the file
format has strings that look like conflict markers.
By default, servers will ignore --pushvars. To enable it add the following to your config-
uration file:
[push]
pushvars.server = true
Returns 0 if push was successful, 1 if nothing to push.
Options:
-f, --force
force push
-r,--rev <REV[+]>
a changeset intended to be included in the destination
-B,--bookmark <BOOKMARK[+]>
bookmark to push
--all-bookmarks
push all bookmarks (EXPERIMENTAL)
-b,--branch <BRANCH[+]>
a specific branch you would like to push
--new-branch
allow pushing a new branch
--pushvars <VALUE[+]>
variables that can be sent to server (ADVANCED)
--publish
push the changeset as public (EXPERIMENTAL)
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
[+] marked option can be specified multiple times
serve
start stand-alone webserver:
hg serve [OPTION]...
Start a local HTTP repository browser and pull server. You can use this for ad-hoc sharing
and browsing of repositories. It is recommended to use a real web server to serve a repos-
itory for longer periods of time.
Please note that the server does not implement access control. This means that, by de-
fault, anybody can read from the server and nobody can write to it by default. Set the
web.allow-push option to * to allow everybody to push to the server. You should use a real
web server if you need to authenticate users.
By default, the server logs accesses to stdout and errors to stderr. Use the -A/--access-
log and -E/--errorlog options to log to files.
To have the server choose a free port number to listen on, specify a port number of 0; in
this case, the server will print the port number it uses.
Returns 0 on success.
Options:
-A,--accesslog <FILE>
name of access log file to write to
-d, --daemon
run server in background
--daemon-postexec <VALUE[+]>
used internally by daemon mode
-E,--errorlog <FILE>
name of error log file to write to
-p,--port <PORT>
port to listen on (default: 8000)
-a,--address <ADDR>
address to listen on (default: all interfaces)
--prefix <PREFIX>
prefix path to serve from (default: server root)
-n,--name <NAME>
name to show in web pages (default: working directory)

--style <STYLE>
template style to use
-6, --ipv6
use IPv6 in addition to IPv4
--certificate <FILE>
SSL certificate file
--print-url
start and print only the URL
-S, --subrepos
recurse into subrepositories
[+] marked option can be specified multiple times
Change creation
commit
commit the specified files or all outstanding changes:
hg commit [OPTION]... [FILE]...
Commit changes to the given files into the repository. Unlike a centralized SCM, this op-
eration is a local operation. See hg push for a way to actively distribute your changes.
If a list of files is omitted, all changes reported by hg status will be committed.
If you are committing the result of a merge, do not provide any filenames or -I/-X fil-
ters.
If no commit message is specified, Mercurial starts your configured editor where you can
enter a message. In case your commit fails, you will find a backup of your message in
.hg/last-message.txt.
The --close-branch flag can be used to mark the current branch head closed. When all heads
of a branch are closed, the branch will be considered closed and no longer listed.
The --amend flag can be used to amend the parent of the working directory with a new com-
mit that contains the changes in the parent in addition to those currently reported by hg
status, if there are any. The old commit is stored in a backup bundle in .hg/strip-backup
(see hg help bundle and hg help unbundle on how to restore it).
Message, user and date are taken from the amended commit unless specified. When a message
isn't specified on the command line, the editor will open with the message of the amended
commit.
It is not possible to amend public changesets (see hg help phases) or changesets that have
children.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if nothing changed.
Examples:
o commit all files ending in .py:
hg commit --include "set:**.py"
o commit all non-binary files:
hg commit --exclude "set:binary()"
o amend the current commit and set the date to now:
hg commit --amend --date now
Options:
-A, --addremove
mark new/missing files as added/removed before committing
--close-branch
mark a branch head as closed
--amend
amend the parent of the working directory
-s, --secret
use the secret phase for committing
-e, --edit
invoke editor on commit messages
--force-close-branch
forcibly close branch from a non-head changeset (ADVANCED)
-i, --interactive
use interactive mode
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
-S, --subrepos
recurse into subrepositories
[+] marked option can be specified multiple times
aliases: ci
Change manipulation
abort
abort an unfinished operation (EXPERIMENTAL):
hg abort
Aborts a multistep operation like graft, histedit, rebase, merge, and unshelve if they are
in an unfinished state.
use --dry-run/-n to dry run the command.
Options:
-n, --dry-run
do not perform actions, just print output
backout
reverse effect of earlier changeset:
hg backout [OPTION]... [-r] REV
Prepare a new changeset with the effect of REV undone in the current working directory. If
no conflicts were encountered, it will be committed immediately.
If REV is the parent of the working directory, then this new changeset is committed auto-
matically (unless --no-commit is specified).
Note hg backout cannot be used to fix either an unwanted or incorrect merge.
Examples:
o Reverse the effect of the parent of the working directory. This backout will be commit-
ted immediately:
hg backout -r .
o Reverse the effect of previous bad revision 23:
hg backout -r 23
o Reverse the effect of previous bad revision 23 and leave changes uncommitted:
hg backout -r 23 --no-commit
hg commit -m "Backout revision 23"
By default, the pending changeset will have one parent, maintaining a linear history. With
--merge, the pending changeset will instead have two parents: the old parent of the work-
ing directory and a new child of REV that simply undoes REV.
Before version 1.7, the behavior without --merge was equivalent to specifying --merge fol-
lowed by hg update --clean . to cancel the merge and leave the child of REV as a head to
be merged separately.
See hg help dates for a list of formats valid for -d/--date.
See hg help revert for a way to restore files to the state of another revision.
Returns 0 on success, 1 if nothing to backout or there are unresolved files.
Options:
--merge
merge with old dirstate parent after backout
--commit
commit if no conflicts were encountered (DEPRECATED)
--no-commit
do not commit
--parent <REV>
parent to choose when backing out merge (DEPRECATED)
-r,--rev <REV>
revision to backout
-e, --edit
invoke editor on commit messages
-t,--tool <TOOL>
specify merge tool
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>

[+] marked option can be specified multiple times
continue
resumes an interrupted operation (EXPERIMENTAL):
hg continue
Finishes a multistep operation like graft, histedit, rebase, merge, and unshelve if they
are in an interrupted state.
use --dry-run/-n to dry run the command.
Options:
-n, --dry-run
do not perform actions, just print output
graft
copy changes from other branches onto the current branch:
hg graft [OPTION]... [-r REV]... REV...
This command uses Mercurial's merge logic to copy individual changes from other branches
without merging branches in the history graph. This is sometimes known as 'backporting' or
'cherry-picking'. By default, graft will copy user, date, and description from the source
changesets.
Changesets that are ancestors of the current revision, that have already been grafted, or
that are merges will be skipped.
If --log is specified, log messages will have a comment appended of the form:
(grafted from CHANGESETHASH)
If --force is specified, revisions will be grafted even if they are already ancestors of,
or have been grafted to, the destination. This is useful when the revisions have since
been backed out.
If a graft merge results in conflicts, the graft process is interrupted so that the cur-
rent merge can be manually resolved. Once all conflicts are addressed, the graft process
can be continued with the -c/--continue option.
The -c/--continue option reapplies all the earlier options.
The --base option exposes more of how graft internally uses merge with a custom base revi-
sion. --base can be used to specify another ancestor than the first and only parent.
The command:
hg graft -r 345 --base 234
is thus pretty much the same as:
hg diff --from 234 --to 345 | hg import
but using merge to resolve conflicts and track moved files.
The result of a merge can thus be backported as a single commit by specifying one of the
merge parents as base, and thus effectively grafting the changes from the other side.
It is also possible to collapse multiple changesets and clean up history by specifying an-
other ancestor as base, much like rebase --collapse --keep.
The commit message can be tweaked after the fact using commit --amend .
For using non-ancestors as the base to backout changes, see the backout command and the
hidden --parent option.
Examples:
o copy a single change to the stable branch and edit its description:
hg update stable
hg graft --edit 9393
o graft a range of changesets with one exception, updating dates:
hg graft -D "2085::2093 and not 2091"
o continue a graft after resolving conflicts:
hg graft -c
o show the source of a grafted changeset:
hg log --debug -r .
o show revisions sorted by date:
hg log -r "sort(all(), date)"
o backport the result of a merge as a single commit:
hg graft -r 123 --base 123^
o land a feature branch as one changeset:
hg up -cr default
hg graft -r featureX --base "ancestor('featureX', 'default')"
See hg help revisions for more about specifying revisions.
Returns 0 on successful completion, 1 if there are unresolved files.

-U, --currentuser
record the current user as committer
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
-t,--tool <TOOL>
specify merge tool
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
merge
merge another revision into working directory:
hg merge [-P] [[-r] REV]
The current working directory is updated with all changes made in the requested revision
since the last common predecessor revision.
Files that changed between either parent are marked as changed for the next commit and a
commit must be performed before any further updates to the repository are allowed. The
next commit will have two parents.
--tool can be used to specify the merge tool used for file merges. It overrides the HG-
MERGE environment variable and your configuration files. See hg help merge-tools for op-
tions.
If no revision is specified, the working directory's parent is a head revision, and the
current branch contains exactly one other head, the other head is merged with by default.
Otherwise, an explicit revision with which to merge must be provided.
See hg help resolve for information on handling file conflicts.
To undo an uncommitted merge, use hg merge --abort which will check out a clean copy of
the original merge parent, losing all changes.
Returns 0 on success, 1 if there are unresolved files.
Options:
-f, --force
force a merge including outstanding changes (DEPRECATED)
-r,--rev <REV>
revision to merge
-P, --preview
review revisions to merge (no merge is performed)
--abort
abort the ongoing merge
-t,--tool <TOOL>
specify merge tool
Change organization
bookmarks
create a new bookmark or list existing bookmarks:
hg bookmarks [OPTIONS]... [NAME]...
Bookmarks are labels on changesets to help track lines of development. Bookmarks are un-
versioned and can be moved, renamed and deleted. Deleting or moving a bookmark has no ef-
fect on the associated changesets.
Creating or updating to a bookmark causes it to be marked as 'active'. The active book-
mark is indicated with a '*'. When a commit is made, the active bookmark will advance to
the new commit. A plain hg update will also advance an active bookmark, if possible. Up-
dating away from a bookmark will cause it to be deactivated.
Bookmarks can be pushed and pulled between repositories (see hg help push and hg help pull
). If a shared bookmark has diverged, a new 'divergent bookmark' of the form 'name@path'
will be created. Using hg merge will resolve the divergence.
Specifying bookmark as '.' to -m/-d/-l options is equivalent to specifying the active
bookmark's name.
A bookmark named '@' has the special property that hg clone will check it out by default
if it exists.
Template:
The following keywords are supported in addition to the common template keywords and func-
tions such as {bookmark}. See also hg help templates.
active Boolean. True if the bookmark is active.
Examples:
o create an active bookmark for a new line of development:
hg book new-feature
o create an inactive bookmark as a place marker:
hg book -i reviewed
o create an inactive bookmark on another changeset:
hg book -r .^ tested
o rename bookmark turkey to dinner:
hg book -m turkey dinner
o move the '@' bookmark from another branch:
hg book -f @
o print only the active bookmark name:
hg book -ql .
Options:
-f, --force
force
-r,--rev <REV>
revision for bookmark action
-d, --delete
delete a given bookmark
-m,--rename <OLD>
rename a given bookmark
-i, --inactive
mark a bookmark inactive
-l, --list
list existing bookmarks
-T,--template <TEMPLATE>
display with template
aliases: bookmark
branch
set or show the current branch name:
hg branch [-fC] [NAME]
Note Branch names are permanent and global. Use hg bookmark to create a light-weight
bookmark instead. See hg help glossary for more information about named branches
and bookmarks.
With no argument, show the current branch name. With one argument, set the working direc-
tory branch name (the branch will not exist in the repository until the next commit).
Standard practice recommends that primary development take place on the 'default' branch.
Unless -f/--force is specified, branch will not let you set a branch name that already ex-
ists.
Use -C/--clean to reset the working directory branch to that of the parent of the working
directory, negating a previous branch change.
Use the command hg update to switch to an existing branch. Use hg commit --close-branch to
mark this branch head as closed. When all heads of a branch are closed, the branch will
be considered closed.
Returns 0 on success.
Options:
-f, --force
set branch name even if it shadows an existing branch
-C, --clean
reset branch name to parent branch name
-r,--rev <VALUE[+]>
change branches of the given revs (EXPERIMENTAL)
[+] marked option can be specified multiple times
branches
list repository named branches:
hg branches [-c]
List the repository's named branches, indicating which ones are inactive. If -c/--closed
is specified, also list branches which have been marked closed (see hg commit
--close-branch).
Use the command hg update to switch to an existing branch.
Template:
The following keywords are supported in addition to the common template keywords and func-
tions such as {branch}. See also hg help templates.
active Boolean. True if the branch is active.
closed Boolean. True if the branch is closed.
current
Boolean. True if it is the current branch.
Returns 0.
Options:
-a, --active
show only branches that have unmerged heads (DEPRECATED)
-c, --closed
show normal and closed branches
-r,--rev <VALUE[+]>
show branch name(s) of the given rev
-T,--template <TEMPLATE>
display with template
[+] marked option can be specified multiple times
phase
set or show the current phase name:
hg phase [-p|-d|-s] [-f] [-r] [REV...]
With no argument, show the phase name of the current revision(s).
With one of -p/--public, -d/--draft or -s/--secret, change the phase value of the speci-
fied revisions.
Unless -f/--force is specified, hg phase won't move changesets from a lower phase to a
higher phase. Phases are ordered as follows:
public < draft < secret
Returns 0 on success, 1 if some phases could not be changed.
(For more information about the phases concept, see hg help phases.)
Options:
-p, --public
set changeset phase to public
-d, --draft
set changeset phase to draft
-s, --secret
set changeset phase to secret
-f, --force
allow to move boundary backward
-r,--rev <REV[+]>
target revision
[+] marked option can be specified multiple times
tag
add one or more tags for the current or given revision:
hg tag [-f] [-l] [-m TEXT] [-d DATE] [-u USER] [-r REV] NAME...
Name a particular revision using <name>.
Tags are used to name particular revisions of the repository and are very useful to com-
pare different revisions, to go back to significant earlier versions or to mark branch
points as releases, etc. Changing an existing tag is normally disallowed; use -f/--force
to override.
If no revision is given, the parent of the working directory is used.
To facilitate version control, distribution, and merging of tags, they are stored as a
file named ".hgtags" which is managed similarly to other project files and can be
hand-edited if necessary. This also means that tagging creates a new commit. The file
".hg/localtags" is used for local tags (not shared among repositories).
Tag commits are usually made at the head of a branch. If the parent of the working direc-
tory is not a branch head, hg tag aborts; use -f/--force to force the tag commit to be
based on a non-head changeset.
See hg help dates for a list of formats valid for -d/--date.
Since tag names have priority over branch names during revision lookup, using an existing
branch name as a tag name is discouraged.
Returns 0 on success.
Options:
-f, --force
force tag
-l, --local
make the tag local
-r,--rev <REV>
revision to tag
--remove
remove a tag
-e, --edit
invoke editor on commit messages
-m,--message <TEXT>
use text as commit message
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
tags
list repository tags:
hg tags
This lists both regular and local tags. When the -v/--verbose switch is used, a third col-
umn "local" is printed for local tags. When the -q/--quiet switch is used, only the tag
name is printed.
Template:
The following keywords are supported in addition to the common template keywords and func-
tions such as {tag}. See also hg help templates.
type String. local for local tags.
Returns 0 on success.
Options:
-T,--template <TEMPLATE>

File content management
annotate
show changeset information by line for each file:
hg annotate [-r REV] [-f] [-a] [-u] [-d] [-n] [-c] [-l] FILE...
List changes in files, showing the revision id responsible for each line.
This command is useful for discovering when a change was made and by whom.
If you include --file, --user, or --date, the revision number is suppressed unless you
also include --number.
Without the -a/--text option, annotate will avoid processing files it detects as binary.
With -a, annotate will annotate the file anyway, although the results will probably be
neither useful nor desirable.
Template:
The following keywords are supported in addition to the common template keywords and func-
tions. See also hg help templates.
lines List of lines with annotation data.
path String. Repository-absolute path of the specified file.
And each entry of {lines} provides the following sub-keywords in addition to {date},
{node}, {rev}, {user}, etc.
line String. Line content.
lineno Integer. Line number at that revision.
path String. Repository-absolute path of the file at that revision.
See hg help templates.operators for the list expansion syntax.
Returns 0 on success.
Options:
-r,--rev <REV>
annotate the specified revision
--follow
follow copies/renames and list the filename (DEPRECATED)
--no-follow

aliases: blame
cat
output the current or given revision of files:
hg cat [OPTION]... FILE...
Print the specified files as they were at the given revision. If no revision is given, the
parent of the working directory is used.
Output may be to a file, in which case the name of the file is given using a template
string. See hg help templates. In addition to the common template keywords, the following
formatting rules are supported:
%%
literal "%" character
%s
basename of file being printed
%d
dirname of file being printed, or '.' if in repository root
%p
root-relative path name of file being printed
%H
changeset hash (40 hexadecimal digits)
%R
changeset revision number
%h
short-form changeset hash (12 hexadecimal digits)
%r
zero-padded changeset revision number

[+] marked option can be specified multiple times
copy
mark files as copied for the next commit:
hg copy [OPTION]... (SOURCE... DEST | --forget DEST...)
Mark dest as having copies of source files. If dest is a directory, copies are put in that
directory. If dest is a file, the source must be a single file.
By default, this command copies the contents of files as they exist in the working direc-
tory. If invoked with -A/--after, the operation is recorded, but no copying is performed.
To undo marking a destination file as copied, use --forget. With that option, all given
(positional) arguments are unmarked as copies. The destination file(s) will be left in
place (still tracked). Note that hg copy --forget behaves the same way as hg rename --for-
get.
This command takes effect with the next commit by default.
Returns 0 on success, 1 if errors are encountered.
Options:
--forget
unmark a destination file as copied
-A, --after
record a copy that has already occurred
--at-rev <REV>
(un)mark copies in the given revision (EXPERIMENTAL)

[+] marked option can be specified multiple times
aliases: cp
diff
diff repository (or selected files):
hg diff [OPTION]... ([-c REV] | [--from REV1] [--to REV2]) [FILE]...
Show differences between revisions for the specified files.
Differences between files are shown using the unified diff format.
Note hg diff may generate unexpected results for merges, as it will default to comparing
against the working directory's first parent changeset if no revisions are speci-
fied.
By default, the working directory files are compared to its first parent. To see the dif-
ferences from another revision, use --from. To see the difference to another revision, use
--to. For example, hg diff --from .^ will show the differences from the working copy's
grandparent to the working copy, hg diff --to . will show the diff from the working copy
to its parent (i.e. the reverse of the default), and hg diff --from 1.0 --to 1.2 will show
the diff between those two revisions.
Alternatively you can specify -c/--change with a revision to see the changes in that
changeset relative to its first parent (i.e. hg diff -c 42 is equivalent to hg diff --from
42^ --to 42)
Without the -a/--text option, diff will avoid generating diffs of files it detects as bi-
nary. With -a, diff will generate a diff anyway, probably with undesirable results.
Use the -g/--git option to generate diffs in the git extended diff format. For more infor-
mation, read hg help diffs.
Examples:
o compare a file in the current working directory to its parent:
hg diff foo.c
o compare two historical versions of a directory, with rename info:
hg diff --git --from 1.0 --to 1.2 lib/
o get change stats relative to the last change on some date:
hg diff --stat --from "date('may 2')"
o diff all newly-added files that contain a keyword:
hg diff "set:added() and grep(GNU)"
o compare a revision and its parents:
hg diff -c 9353 # compare against first parent
hg diff --from 9353^ --to 9353 # same using revset syntax
hg diff --from 9353^2 --to 9353 # compare against the second parent
Returns 0 on success.

[+] marked option can be specified multiple times
grep
search for a pattern in specified files:
hg grep [--diff] [OPTION]... PATTERN [FILE]...
Search the working directory or revision history for a regular expression in the specified
files for the entire repository.
By default, grep searches the repository files in the working directory and prints the
files where it finds a match. To specify historical revisions instead of the working di-
rectory, use the --rev flag.
To search instead historical revision differences that contains a change in match status
("-" for a match that becomes a non-match, or "+" for a non-match that becomes a match),
use the --diff flag.
PATTERN can be any Python (roughly Perl-compatible) regular expression.
If no FILEs are specified and the --rev flag isn't supplied, all files in the working di-
rectory are searched. When using the --rev flag and specifying FILEs, use the --follow ar-
gument to also follow the specified FILEs across renames and copies.
Template:
The following keywords are supported in addition to the common template keywords and func-
tions. See also hg help templates.
change String. Character denoting insertion + or removal -. Available if --diff is speci-
fied.
lineno Integer. Line number of the match.
path String. Repository-absolute path of the file.
texts List of text chunks.
And each entry of {texts} provides the following sub-keywords.

Change navigation
bisect
subdivision search of changesets:
hg bisect [-gbsr] [-U] [-c CMD] [REV]
This command helps to find changesets which introduce problems. To use, mark the earliest
changeset you know exhibits the problem as bad, then mark the latest changeset which is
free from the problem as good. Bisect will update your working directory to a revision for
testing (unless the -U/--noupdate option is specified). Once you have performed tests,
mark the working directory as good or bad, and bisect will either update to another candi-
date changeset or announce that it has found the bad revision.
As a shortcut, you can also use the revision argument to mark a revision as good or bad
without checking it out first.
If you supply a command, it will be used for automatic bisection. The environment vari-
able HG_NODE will contain the ID of the changeset being tested. The exit status of the
command will be used to mark revisions as good or bad: status 0 means good, 125 means to
skip the revision, 127 (command not found) will abort the bisection, and any other
non-zero exit status means the revision is bad.
Some examples:
o start a bisection with known bad revision 34, and good revision 12:
hg bisect --bad 34
hg bisect --good 12
o advance the current bisection by marking current revision as good or bad:
hg bisect --good
hg bisect --bad
o mark the current revision, or a known revision, to be skipped (e.g. if that revision is
not usable because of another issue):
hg bisect --skip
hg bisect --skip 23
o skip all revisions that do not touch directories foo or bar:
hg bisect --skip "!( file('path:foo') & file('path:bar') )"
o forget the current bisection:
hg bisect --reset
o use 'make && make tests' to automatically find the first broken revision:
hg bisect --reset
hg bisect --bad 34
hg bisect --good 12
hg bisect --command "make && make tests"
o see all changesets whose states are already known in the current bisection:
hg log -r "bisect(pruned)"
o see the changeset currently being bisected (especially useful if running with -U/--noup-
date):
hg log -r "bisect(current)"
o see all changesets that took part in the current bisection:
hg log -r "bisect(range)"
o you can even get a nice graph:
hg log --graph -r "bisect(range)"
See hg help revisions.bisect for more about the bisect() predicate.
Returns 0 on success.
Options:
-r, --reset
reset bisect state
-g, --good
mark changeset good
-b, --bad
mark changeset bad
-s, --skip
skip testing changeset
-e, --extend
extend the bisect range
-c,--command <CMD>
use command to check changeset state
-U, --noupdate
do not update to target
heads
show branch heads:
hg heads [-ct] [-r STARTREV] [REV]...
With no arguments, show all open branch heads in the repository. Branch heads are change-
sets that have no descendants on the same branch. They are where development generally
takes place and are the usual targets for update and merge operations.
If one or more REVs are given, only open branch heads on the branches associated with the
specified changesets are shown. This means that you can use hg heads . to see the heads on
the currently checked-out branch.
If -c/--closed is specified, also show branch heads marked closed (see hg commit
--close-branch).
If STARTREV is specified, only those heads that are descendants of STARTREV will be dis-
played.
If -t/--topo is specified, named branch mechanics will be ignored and only topological
heads (changesets with no children) will be shown.
Returns 0 if matching heads are found, 1 if not.
Options:
-r,--rev <STARTREV>
show only heads which are descendants of STARTREV
-t, --topo
show topological heads only
-a, --active
show active branchheads only (DEPRECATED)
-c, --closed
show normal and closed branch heads
--style <STYLE>
display using template map file (DEPRECATED)
-T,--template <TEMPLATE>

identify
identify the working directory or specified revision:
hg identify [-nibtB] [-r REV] [SOURCE]
Print a summary identifying the repository state at REV using one or two parent hash iden-
tifiers, followed by a "+" if the working directory has uncommitted changes, the branch
name (if not default), a list of tags, and a list of bookmarks.
When REV is not given, print a summary of the current state of the repository including
the working directory. Specify -r. to get information of the working directory parent
without scanning uncommitted changes.
Specifying a path to a repository root or Mercurial bundle will cause lookup to operate on
that repository/bundle.
Template:
The following keywords are supported in addition to the common template keywords and func-
tions. See also hg help templates.
dirty String. Character + denoting if the working directory has uncommitted changes.
id String. One or two nodes, optionally followed by +.
parents
List of strings. Parent nodes of the changeset.
Examples:
o generate a build identifier for the working directory:
hg id --id > build-id.dat
o find the revision corresponding to a tag:
hg id -n -r 1.3
o check the most recent revision of a remote repository:
hg id -r tip https://www.mercurial-scm.org/repo/hg/
See hg log for generating more information about specific revisions, including full hash
identifiers.
Returns 0 if successful.
Options:
-r,--rev <REV>
identify the specified revision
-n, --num
show local revision number
-i, --id
show global revision id
-b, --branch
show branch
-t, --tags
show tags
-B, --bookmarks
show bookmarks
-e,--ssh <CMD>

--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
-T,--template <TEMPLATE>

aliases: id
log
show revision history of entire repository or files:
hg log [OPTION]... [FILE]
Print the revision history of the specified files or the entire project.
If no revision range is specified, the default is tip:0 unless --follow is set.
File history is shown without following rename or copy history of files. Use -f/--follow
with a filename to follow history across renames and copies. --follow without a filename
will only show ancestors of the starting revisions. The starting revisions can be speci-
fied by -r/--rev, which default to the working directory parent.
By default this command prints revision number and changeset id, tags, non-trivial par-
ents, user, date and time, and a summary for each commit. When the -v/--verbose switch is
used, the list of changed files and full commit message are shown.
With --graph the revisions are shown as an ASCII art DAG with the most recent changeset at
the top. 'o' is a changeset, '@' is a working directory parent, '%' is a changeset in-
volved in an unresolved merge conflict, '_' closes a branch, 'x' is obsolete, '*' is un-
stable, and '+' represents a fork where the changeset from the lines below is a parent of
the 'o' merge on the same line. Paths in the DAG are represented with '|', '/' and so
forth. ':' in place of a '|' indicates one or more revisions in a path are omitted.
Use -L/--line-range FILE,M:N options to follow the history of lines from M to N in FILE.
With -p/--patch only diff hunks affecting specified line range will be shown. This option
requires --follow; it can be specified multiple times. Currently, this option is not com-
patible with --graph. This option is experimental.
Note hg log --patch may generate unexpected diff output for merge changesets, as it will
only compare the merge changeset against its first parent. Also, only files differ-
ent from BOTH parents will appear in files:.
Note For performance reasons, hg log FILE may omit duplicate changes made on branches
and will not show removals or mode changes. To see all such changes, use the --re-
moved switch.
Note The history resulting from -L/--line-range options depends on diff options; for in-
stance if white-spaces are ignored, respective changes with only white-spaces in
specified line range will not be listed.
Some examples:
o changesets with full descriptions and file lists:
hg log -v
o changesets ancestral to the working directory:
hg log -f
o last 10 commits on the current branch:
hg log -l 10 -b .
o changesets showing all modifications of a file, including removals:
hg log --removed file.c
o all changesets that touch a directory, with diffs, excluding merges:
hg log -Mp lib/
o all revision numbers that match a keyword:
hg log -k bug --template "{rev}\n"
o the full hash identifier of the working directory parent:
hg log -r . --template "{node}\n"
o list available log templates:
hg log -T list
o check if a given changeset is included in a tagged release:
hg log -r "a21ccf and ancestor(1.9)"
o find all changesets by some user in a date range:
hg log -k alice -d "may 2008 to jul 2008"
o summary of all changesets after the last tag:
hg log -r "last(tagged())::" --template "{desc|firstline}\n"
o changesets touching lines 13 to 23 for file.c:
hg log -L file.c,13:23
o changesets touching lines 13 to 23 for file.c and lines 2 to 6 of main.c with patch:
hg log -L file.c,13:23 -L main.c,2:6 -p
See hg help dates for a list of formats valid for -d/--date.
See hg help revisions for more about specifying and ordering revisions.
See hg help templates for more about pre-packaged styles and specifying custom templates.
The default template used by the log command can be customized via the command-tem-
plates.log configuration setting.
Returns 0 on success.

parents
show the parents of the working directory or revision (DEPRECATED):
hg parents [-r REV] [FILE]
Print the working directory's parent revisions. If a revision is given via -r/--rev, the
parent of that revision will be printed. If a file argument is given, the revision in
which the file was last changed (before the working directory revision or the argument to
--rev if given) is printed.
This command is equivalent to:
hg log -r "p1()+p2()" or
hg log -r "p1(REV)+p2(REV)" or
hg log -r "max(::p1() and file(FILE))+max(::p2() and file(FILE))" or
hg log -r "max(::p1(REV) and file(FILE))+max(::p2(REV) and file(FILE))"
See hg summary and hg help revsets for related information.
Returns 0 on success.

tip
show the tip revision (DEPRECATED):
hg tip [-p] [-g]
The tip revision (usually just called the tip) is the changeset most recently added to the
repository (and therefore the most recently changed head).
If you have just made a commit, that commit will be the tip. If you have just pulled
changes from another repository, the tip of that repository becomes the current tip. The
"tip" tag is special and cannot be renamed or assigned to a different changeset.
This command is deprecated, please use hg heads instead.

Working directory management
add
add the specified files on the next commit:
hg add [OPTION]... [FILE]...
Schedule files to be version controlled and added to the repository.
The files will be added to the repository at the next commit. To undo an add before that,
see hg forget.
If no names are given, add all files to the repository (except files matching .hgignore).
Examples:
o New (unknown) files are added automatically by hg add:
$ ls
foo.c
$ hg status
? foo.c
$ hg add
adding foo.c
$ hg status
A foo.c
o Specific files to be added can be specified:
$ ls
bar.c foo.c
$ hg status
? bar.c
? foo.c
$ hg add bar.c
$ hg status
A bar.c
? foo.c
Returns 0 if all files are successfully added.
Options:
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-S, --subrepos
recurse into subrepositories
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
addremove
add all new files, delete all missing files:
hg addremove [OPTION]... [FILE]...
Add all new files and remove all missing files from the repository.
Unless names are given, new files are ignored if they match any of the patterns in .hgig-
nore. As with add, these changes take effect at the next commit.
Use the -s/--similarity option to detect renamed files. This option takes a percentage be-
tween 0 (disabled) and 100 (files must be identical) as its parameter. With a parameter
greater than 0, this compares every removed file with every added file and records those
similar enough as renames. Detecting renamed files this way can be expensive. After using
this option, hg status -C can be used to check which files were identified as moved or re-
named. If not specified, -s/--similarity defaults to 100 and only renames of identical
files are detected.
Examples:
o A number of files (bar.c and foo.c) are new, while foobar.c has been removed (without
using hg remove) from the repository:
$ ls
bar.c foo.c
$ hg status
! foobar.c
? bar.c
? foo.c
$ hg addremove
adding bar.c
adding foo.c
removing foobar.c
$ hg status
A bar.c
A foo.c
R foobar.c
o A file foobar.c was moved to foo.c without using hg rename. Afterwards, it was
edited slightly:
$ ls
foo.c
$ hg status
! foobar.c
? foo.c
$ hg addremove --similarity 90
removing foobar.c
adding foo.c
recording removal of foobar.c as rename to foo.c (94% similar)
$ hg status -C
A foo.c
foobar.c
R foobar.c
Returns 0 if all files are successfully added.
Options:
-s,--similarity <SIMILARITY>
guess renamed files by similarity (0<=s<=100)
-S, --subrepos

-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-n, --dry-run

[+] marked option can be specified multiple times
files
list tracked files:
hg files [OPTION]... [FILE]...
Print files under Mercurial control in the working directory or specified revision for
given files (excluding removed files). Files can be specified as filenames or filesets.
If no files are given to match, this command prints the names of all files under Mercurial
control.
Template:
The following keywords are supported in addition to the common template keywords and func-
tions. See also hg help templates.
flags String. Character denoting file's symlink and executable bits.
path String. Repository-absolute path of the file.
size Integer. Size of the file in bytes.
Examples:
o list all files under the current directory:
hg files .
o shows sizes and flags for current revision:
hg files -vr .
o list all files named README:
hg files -I "**/README"
o list all binary files:
hg files "set:binary()"
o find files containing a regular expression:
hg files "set:grep('bob')"
o search tracked file contents with xargs and grep:
hg files -0 | xargs -0 grep foo
See hg help patterns and hg help filesets for more information on specifying file pat-
terns.
Returns 0 if a match is found, 1 otherwise.
Options:
-r,--rev <REV>
search the repository as it is in REV
-0, --print0
end filenames with NUL, for use with xargs
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-T,--template <TEMPLATE>
display with template
-S, --subrepos
recurse into subrepositories
[+] marked option can be specified multiple times
forget
forget the specified files on the next commit:
hg forget [OPTION]... FILE...
Mark the specified files so they will no longer be tracked after the next commit.
This only removes files from the current branch, not from the entire project history, and
it does not delete them from the working directory.
To delete the file from the working directory, see hg remove.
To undo a forget before the next commit, see hg add.
Examples:
o forget newly-added binary files:
hg forget "set:added() and binary()"
o forget files that would be excluded by .hgignore:
hg forget "set:hgignore()"
Returns 0 on success.
Options:
-i, --interactive
use interactive mode
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
locate
locate files matching specific patterns (DEPRECATED):
hg locate [OPTION]... [PATTERN]...
Print files under Mercurial control in the working directory whose names match the given
patterns.
By default, this command searches all directories in the working directory. To search just
the current directory and its subdirectories, use "--include .".
If no patterns are given to match, this command prints the names of all files under Mercu-
rial control in the working directory.
If you want to feed the output of this command into the "xargs" command, use the -0 option
to both this command and "xargs". This will avoid the problem of "xargs" treating single
filenames that contain whitespace as multiple filenames.
See hg help files for a more versatile command.
Returns 0 if a match is found, 1 otherwise.
Options:
-r,--rev <REV>
search the repository as it is in REV
-0, --print0
end filenames with NUL, for use with xargs
-f, --fullpath
print complete paths from the filesystem root
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
purge
removes files not tracked by Mercurial:
hg purge [OPTION]... [DIR]...
Delete files not known to Mercurial. This is useful to test local and uncommitted changes
in an otherwise-clean source tree.
This means that purge will delete the following by default:
o Unknown files: files marked with "?" by hg status
o Empty directories: in fact Mercurial ignores directories unless they contain files under
source control management
But it will leave untouched:
o Modified and unmodified tracked files
o Ignored files (unless -i or --all is specified)
o New files added to the repository (with hg add)
The --files and --dirs options can be used to direct purge to delete only files, only di-
rectories, or both. If neither option is given, both will be deleted.
If directories are given on the command line, only files in these directories are consid-
ered.
Be careful with purge, as you could irreversibly delete some files you forgot to add to
the repository. If you only want to print the list of files that this program would
delete, use the --print option.
Options:
-a, --abort-on-err
abort if an error occurs
--all purge ignored files too
-i, --ignored
purge only ignored files
--dirs purge empty directories
--files
purge files
-p, --print
print filenames instead of deleting them
-0, --print0
end filenames with NUL, for use with xargs (implies -p/--print)
--confirm
ask before permanently deleting files
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
aliases: clean
remove
remove the specified files on the next commit:
hg remove [OPTION]... FILE...
Schedule the indicated files for removal from the current branch.
This command schedules the files to be removed at the next commit. To undo a remove be-
fore that, see hg revert. To undo added files, see hg forget.
-A/--after can be used to remove only files that have already been deleted, -f/--force can
be used to force deletion, and -Af can be used to remove files from the next revision
without deleting them from the working directory.
The following table details the behavior of remove for different file states (columns) and
option combinations (rows). The file states are Added [A], Clean [C], Modified [M] and
Missing [!] (as reported by hg status). The actions are Warn, Remove (from branch) and
Delete (from disk):
+----------+---+----+----+---+
|opt/state | A | C | M | ! |
+----------+---+----+----+---+
|none | W | RD | W | R |
+----------+---+----+----+---+
|-f | R | RD | RD | R |
+----------+---+----+----+---+
|-A | W | W | W | R |
+----------+---+----+----+---+
|-Af | R | R | R | R |
+----------+---+----+----+---+
Note hg remove never deletes files in Added [A] state from the working directory, not
even if --force is specified.
Returns 0 on success, 1 if any warnings encountered.
Options:
-A, --after
record delete for missing files
-f, --force
forget added files, delete modified files
-S, --subrepos
recurse into subrepositories
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
aliases: rm
rename
rename files; equivalent of copy + remove:
hg rename [OPTION]... SOURCE... DEST
Mark dest as copies of sources; mark sources for deletion. If dest is a directory, copies
are put in that directory. If dest is a file, there can only be one source.
By default, this command copies the contents of files as they exist in the working direc-
tory. If invoked with -A/--after, the operation is recorded, but no copying is performed.
To undo marking a destination file as renamed, use --forget. With that option, all given
(positional) arguments are unmarked as renames. The destination file(s) will be left in
place (still tracked). The source file(s) will not be restored. Note that hg rename --for-
get behaves the same way as hg copy --forget.
This command takes effect with the next commit by default.
Returns 0 on success, 1 if errors are encountered.
Options:
--forget
unmark a destination file as renamed
-A, --after
record a rename that has already occurred
--at-rev <REV>
(un)mark renames in the given revision (EXPERIMENTAL)
-f, --force
forcibly move over an existing managed file
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>

aliases: move mv
resolve
redo merges or set/view the merge status of files:
hg resolve [OPTION]... [FILE]...
Merges with unresolved conflicts are often the result of non-interactive merging using the
internal:merge configuration setting, or a command-line merge tool like diff3. The resolve
command is used to manage the files involved in a merge, after hg merge has been run, and
before hg commit is run (i.e. the working directory must have two parents). See hg help
merge-tools for information on configuring merge tools.
The resolve command can be used in the following ways:
o hg resolve [--re-merge] [--tool TOOL] FILE...: attempt to re-merge the specified files,
discarding any previous merge attempts. Re-merging is not performed for files already
marked as resolved. Use --all/-a to select all unresolved files. --tool can be used to
specify the merge tool used for the given files. It overrides the HGMERGE environment
variable and your configuration files. Previous file contents are saved with a .orig
suffix.
o hg resolve -m [FILE]: mark a file as having been resolved (e.g. after having manually
fixed-up the files). The default is to mark all unresolved files.
o hg resolve -u [FILE]...: mark a file as unresolved. The default is to mark all resolved
files.
o hg resolve -l: list files which had or still have conflicts. In the printed list, U =
unresolved and R = resolved. You can use set:unresolved() or set:resolved() to filter
the list. See hg help filesets for details.
Note Mercurial will not let you commit files with unresolved merge conflicts. You must
use hg resolve -m ... before you can commit after a conflicting merge.
Template:
The following keywords are supported in addition to the common template keywords and func-
tions. See also hg help templates.
mergestatus
String. Character denoting merge conflicts, U or R.
path String. Repository-absolute path of the file.
Returns 0 on success, 1 if any files fail a resolve attempt.
Options:
-a, --all
select all unresolved files
-l, --list
list state of files needing merge
-m, --mark
mark files as resolved
-u, --unmark

-T,--template <TEMPLATE>

[+] marked option can be specified multiple times
revert
restore files to their checkout state:
hg revert [OPTION]... [-r REV] [NAME]...
Note To check out earlier revisions, you should use hg update REV. To cancel an uncom-
mitted merge (and lose your changes), use hg merge --abort.
With no revision specified, revert the specified files or directories to the contents they
had in the parent of the working directory. This restores the contents of files to an un-
modified state and unschedules adds, removes, copies, and renames. If the working direc-
tory has two parents, you must explicitly specify a revision.
Using the -r/--rev or -d/--date options, revert the given files or directories to their
states as of a specific revision. Because revert does not change the working directory
parents, this will cause these files to appear modified. This can be helpful to "back out"
some or all of an earlier change. See hg backout for a related method.
Modified files are saved with a .orig suffix before reverting. To disable these backups,
use --no-backup. It is possible to store the backup files in a custom directory relative
to the root of the repository by setting the ui.origbackuppath configuration option.
See hg help dates for a list of formats valid for -d/--date.
See hg help backout for a way to reverse the effect of an earlier changeset.
Returns 0 on success.
Options:
-a, --all
revert all changes when no arguments given
-d,--date <DATE>
tipmost revision matching date
-r,--rev <REV>
revert to the specified revision
-C, --no-backup
do not save backup copies of files
-i, --interactive

Template:
The following keywords are supported in addition to the common template keywords and func-
tions. See also hg help templates.
hgpath String. Path to the .hg directory.
storepath
String. Path to the directory holding versioned data.
Returns 0 on success.
Options:
-T,--template <TEMPLATE>
display with template
shelve
save and set aside changes from the working directory:
hg shelve [OPTION]... [FILE]...
Shelving takes files that "hg status" reports as not clean, saves the modifications to a
bundle (a shelved change), and reverts the files so that their state in the working direc-
tory becomes clean.
To restore these changes to the working directory, using "hg unshelve"; this will work
even if you switch to a different commit.
When no files are specified, "hg shelve" saves all not-clean files. If specific files or
directories are named, only changes to those files are shelved.
In bare shelve (when no files are specified, without interactive, include and exclude op-
tion), shelving remembers information if the working directory was on newly created
branch, in other words working directory was on different branch than its first parent. In
this situation unshelving restores branch information to the working directory.
Each shelved change has a name that makes it easier to find later. The name of a shelved
change defaults to being based on the active bookmark, or if there is no active bookmark,
the current named branch. To specify a different name, use --name.
To see a list of existing shelved changes, use the --list option. For each shelved change,
this will print its name, age, and description; use --patch or --stat for more details.
To delete specific shelved changes, use --delete. To delete all shelved changes, use
--cleanup.
Options:
-A, --addremove
mark new/missing files as added/removed before shelving
-u, --unknown
store unknown files in the shelve
--cleanup
delete all shelved changes
--date <DATE>
shelve with the specified commit date
-d, --delete
delete the named shelved change(s)
-e, --edit
invoke editor on commit messages
-k, --keep
shelve, but keep changes in the working directory
-l, --list
list current shelves
-m,--message <TEXT>
use text as shelve message
-n,--name <NAME>
use the given name for the shelved commit
-p, --patch
output patches for changes (provide the names of the shelved changes as positional
arguments)
-i, --interactive
interactive mode
--stat output diffstat-style summary of changes (provide the names of the shelved changes
as positional arguments)
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
status
show changed files in the working directory:
hg status [OPTION]... [FILE]...
Show status of files in the repository. If names are given, only files that match are
shown. Files that are clean or ignored or the source of a copy/move operation, are not
listed unless -c/--clean, -i/--ignored, -C/--copies or -A/--all are given. Unless options
described with "show only ..." are given, the options -mardu are used.
Option -q/--quiet hides untracked (unknown and ignored) files unless explicitly requested
with -u/--unknown or -i/--ignored.
Note hg status may appear to disagree with diff if permissions have changed or a merge
has occurred. The standard diff format does not report permission changes and diff
only reports changes relative to one merge parent.
If one revision is given, it is used as the base revision. If two revisions are given,
the differences between them are shown. The --change option can also be used as a shortcut
to list the changed files of a revision from its first parent.
The codes used to show the status of files are:
M = modified
A = added
R = removed
C = clean
! = missing (deleted by non-hg command, but still tracked)
? = not tracked
I = ignored
= origin of the previous file (with --copies)
The -t/--terse option abbreviates the output by showing only the directory name if all the
files in it share the same status. The option takes an argument indicating the statuses to
abbreviate: 'm' for 'modified', 'a' for 'added', 'r' for 'removed', 'd' for 'deleted', 'u'
for 'unknown', 'i' for 'ignored' and 'c' for clean.
It abbreviates only those statuses which are passed. Note that clean and ignored files are
not displayed with '--terse ic' unless the -c/--clean and -i/--ignored options are also
used.
The -v/--verbose option shows information when the repository is in an unfinished merge,
shelve, rebase state etc. You can have this behavior turned on by default by enabling the
commands.status.verbose option.
You can skip displaying some of these states by setting commands.status.skipstates to one
or more of: 'bisect', 'graft', 'histedit', 'merge', 'rebase', or 'unshelve'.
Template:
The following keywords are supported in addition to the common template keywords and func-
tions. See also hg help templates.
path String. Repository-absolute path of the file.
source String. Repository-absolute path of the file originated from. Available if
--copies is specified.
status String. Character denoting file's status.
Examples:
o show changes in the working directory relative to a changeset:
hg status --rev 9353
o show changes in the working directory relative to the current directory (see hg help
patterns for more information):
hg status re:
o show all changes including copies in an existing changeset:
hg status --copies --change 9353
o get a NUL separated list of added files, suitable for xargs:
hg status -an0
o show more information about the repository status, abbreviating added, removed, modi-
fied, deleted, and untracked paths:
hg status -v -t mardu
Returns 0 on success.
Options:
-A, --all
show status of all files
-m, --modified
show only modified files
-a, --added

summary
summarize working directory state:
hg summary [--remote]
This generates a brief summary of the working directory state, including parents, branch,
commit status, phase and available updates.
With the --remote option, this will check the default paths for incoming and outgoing
changes. This can be time-consuming.
Returns 0 on success.
Options:
--remote
check for push and pull
aliases: sum
unshelve
restore a shelved change to the working directory:
hg unshelve [OPTION]... [[-n] SHELVED]
This command accepts an optional name of a shelved change to restore. If none is given,
the most recent shelved change is used.
If a shelved change is applied successfully, the bundle that contains the shelved changes
is moved to a backup location (.hg/shelve-backup).
Since you can restore a shelved change on top of an arbitrary commit, it is possible that
unshelving will result in a conflict between your changes and the commits you are unshelv-
ing onto. If this occurs, you must resolve the conflict, then use --continue to complete
the unshelve operation. (The bundle will not be moved until you successfully complete the
unshelve.)
(Alternatively, you can use --abort to abandon an unshelve that causes a conflict. This
reverts the unshelved changes, and leaves the bundle in place.)
If bare shelved change (without interactive, include and exclude option) was done on newly
created branch it would restore branch information to the working directory.
After a successful unshelve, the shelved changes are stored in a backup directory. Only
the N most recent backups are kept. N defaults to 10 but can be overridden using the
shelve.maxbackups configuration option.
Timestamp in seconds is used to decide order of backups. More than maxbackups backups are
kept, if same timestamp prevents from deciding exact order of them, for safety.
Selected changes can be unshelved with --interactive flag. The working directory is up-
dated with the selected changes, and only the unselected changes remain shelved. Note:
The whole shelve is applied to working directory first before running interactively. So,
this will bring up all the conflicts between working directory and the shelve, irrespec-
tive of which changes will be unshelved.
Options:
-a, --abort
abort an incomplete unshelve operation
-c, --continue
continue an incomplete unshelve operation
-i, --interactive
use interactive mode (EXPERIMENTAL)
-k, --keep
keep shelve after unshelving
-n,--name <NAME>
restore shelved change with given name
-t,--tool <VALUE>
specify merge tool
--date <DATE>
set date for temporary commits (DEPRECATED)
update
update working directory (or switch revisions):
hg update [-C|-c|-m] [-d DATE] [[-r] REV]
Update the repository's working directory to the specified changeset. If no changeset is
specified, update to the tip of the current named branch and move the active bookmark (see
hg help bookmarks).
Update sets the working directory's parent revision to the specified changeset (see hg
help parents).
If the changeset is not a descendant or ancestor of the working directory's parent and
there are uncommitted changes, the update is aborted. With the -c/--check option, the
working directory is checked for uncommitted changes; if none are found, the working di-
rectory is updated to the specified changeset.
The -C/--clean, -c/--check, and -m/--merge options control what happens if the working di-
rectory contains uncommitted changes. At most of one of them can be specified.
1. If no option is specified, and if the requested changeset is an ancestor or descendant
of the working directory's parent, the uncommitted changes are merged into the re-
quested changeset and the merged result is left uncommitted. If the requested changeset
is not an ancestor or descendant (that is, it is on another branch), the update is
aborted and the uncommitted changes are preserved.
2. With the -m/--merge option, the update is allowed even if the requested changeset is
not an ancestor or descendant of the working directory's parent.
3. With the -c/--check option, the update is aborted and the uncommitted changes are pre-
served.
4. With the -C/--clean option, uncommitted changes are discarded and the working directory
is updated to the requested changeset.
To cancel an uncommitted merge (and lose your changes), use hg merge --abort.
Use null as the changeset to remove the working directory (like hg clone -U).
If you want to revert just one file to an older revision, use hg revert [-r REV] NAME.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if there are unresolved files.
Options:
-C, --clean
discard uncommitted changes (no backup)
-c, --check

-m, --merge

Change import/export
archive
create an unversioned archive of a repository revision:
hg archive [OPTION]... DEST
By default, the revision used is the parent of the working directory; use -r/--rev to
specify a different revision.
The archive type is automatically detected based on file extension (to override, use
-t/--type).
Examples:
o create a zip file containing the 1.0 release:
hg archive -r 1.0 project-1.0.zip
o create a tarball excluding .hg files:
hg archive project.tar.gz -X ".hg*"
Valid types are:
files
a directory full of files (default)
tar
tar archive, uncompressed
tbz2
tar archive, compressed using bzip2
tgz
tar archive, compressed using gzip
txz
tar archive, compressed using lzma (only in Python 3)
uzip
zip archive, uncompressed
zip
zip archive, compressed using deflate
The exact name of the destination archive or directory is given using a format string; see
hg help export for details.
Each member added to an archive file has a directory prefix prepended. Use -p/--prefix to
specify a format string for the prefix. The default is the basename of the archive, with
suffixes removed.
Returns 0 on success.
Options:
--no-decode
do not pass files through decoders
-p,--prefix <PREFIX>
directory prefix for files in archive
-r,--rev <REV>
revision to distribute
-t,--type <TYPE>
type of distribution to create
-S, --subrepos
recurse into subrepositories
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
bundle
create a bundle file:
hg bundle [-f] [-t BUNDLESPEC] [-a] [-r REV]... [--base REV]... FILE [DEST]...
Generate a bundle file containing data to be transferred to another repository.
To create a bundle containing all changesets, use -a/--all (or --base null). Otherwise, hg
assumes the destination will have all the nodes you specify with --base parameters. Other-
wise, hg will assume the repository has all the nodes in destination, or default-push/de-
fault if no destination is specified, where destination is the repositories you provide
through DEST option.
You can change bundle format with the -t/--type option. See hg help bundlespec for docu-
mentation on this format. By default, the most appropriate format is used and compression
defaults to bzip2.
The bundle file can then be transferred using conventional means and applied to another
repository with the unbundle or pull command. This is useful when direct push and pull are
not available or when exporting an entire repository is undesirable.
Applying bundles preserves all changeset contents including permissions, copy/rename in-
formation, and revision history.
Returns 0 on success, 1 if no changes found.
Options:
-f, --force
run even when the destination is unrelated
-r,--rev <REV[+]>
a changeset intended to be added to the destination
-b,--branch <BRANCH[+]>
a specific branch you would like to bundle
--base <REV[+]>
a base changeset assumed to be available at the destination
-a, --all
bundle all changesets in the repository
-t,--type <TYPE>
bundle compression type to use (default: bzip2)
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
[+] marked option can be specified multiple times
export
dump the header and diffs for one or more changesets:
hg export [OPTION]... [-o OUTFILESPEC] [-r] [REV]...
Print the changeset header and diffs for one or more revisions. If no revision is given,
the parent of the working directory is used.
The information shown in the changeset header is: author, date, branch name (if non-de-
fault), changeset hash, parent(s) and commit comment.
Note hg export may generate unexpected diff output for merge changesets, as it will com-
pare the merge changeset against its first parent only.
Output may be to a file, in which case the name of the file is given using a template
string. See hg help templates. In addition to the common template keywords, the following
formatting rules are supported:
%%
literal "%" character
%H
changeset hash (40 hexadecimal digits)
%N
number of patches being generated
%R
changeset revision number
%b
basename of the exporting repository
%h
short-form changeset hash (12 hexadecimal digits)
%m
first line of the commit message (only alphanumeric characters)
%n
zero-padded sequence number, starting at 1
%r
zero-padded changeset revision number
\
literal "" character
Without the -a/--text option, export will avoid generating diffs of files it detects as
binary. With -a, export will generate a diff anyway, probably with undesirable results.
With -B/--bookmark changesets reachable by the given bookmark are selected.
Use the -g/--git option to generate diffs in the git extended diff format. See hg help
diffs for more information.
With the --switch-parent option, the diff will be against the second parent. It can be
useful to review a merge.
Template:
The following keywords are supported in addition to the common template keywords and func-
tions. See also hg help templates.
diff String. Diff content.
parents
List of strings. Parent nodes of the changeset.
Examples:
o use export and import to transplant a bugfix to the current branch:
hg export -r 9353 | hg import -
o export all the changesets between two revisions to a file with rename information:
hg export --git -r 123:150 > changes.txt
o split outgoing changes into a series of patches with descriptive names:
hg export -r "outgoing()" -o "%n-%m.patch"
Returns 0 on success.
Options:
-B,--bookmark <BOOKMARK>
export changes only reachable by given bookmark
-o,--output <FORMAT>
print output to file with formatted name
--switch-parent
diff against the second parent
-r,--rev <REV[+]>
revisions to export
-a, --text
treat all files as text
-g, --git
use git extended diff format (DEFAULT: diff.git)
--binary
generate binary diffs in git mode (default)
--nodates
omit dates from diff headers
-T,--template <TEMPLATE>
display with template
[+] marked option can be specified multiple times
import
import an ordered set of patches:
hg import [OPTION]... PATCH...
Import a list of patches and commit them individually (unless --no-commit is specified).
To read a patch from standard input (stdin), use "-" as the patch name. If a URL is speci-
fied, the patch will be downloaded from there.
Import first applies changes to the working directory (unless --bypass is specified), im-
port will abort if there are outstanding changes.
Use --bypass to apply and commit patches directly to the repository, without affecting the
working directory. Without --exact, patches will be applied on top of the working direc-
tory parent revision.
You can import a patch straight from a mail message. Even patches as attachments work (to
use the body part, it must have type text/plain or text/x-patch). From and Subject headers
of email message are used as default committer and commit message. All text/plain body
parts before first diff are added to the commit message.
If the imported patch was generated by hg export, user and description from patch override
values from message headers and body. Values given on command line with -m/--message and
-u/--user override these.
If --exact is specified, import will set the working directory to the parent of each patch
before applying it, and will abort if the resulting changeset has a different ID than the
one recorded in the patch. This will guard against various ways that portable patch for-
mats and mail systems might fail to transfer Mercurial data or metadata. See hg bundle for
lossless transmission.
Use --partial to ensure a changeset will be created from the patch even if some hunks fail
to apply. Hunks that fail to apply will be written to a <target-file>.rej file. Conflicts
can then be resolved by hand before hg commit --amend is run to update the created change-
set. This flag exists to let people import patches that partially apply without losing the
associated metadata (author, date, description, ...).
Note When no hunks apply cleanly, hg import --partial will create an empty changeset,
importing only the patch metadata.
With -s/--similarity, hg will attempt to discover renames and copies in the patch in the
same way as hg addremove.
It is possible to use external patch programs to perform the patch by setting the ui.patch
configuration option. For the default internal tool, the fuzz can also be configured via
patch.fuzz. See hg help config for more information about configuration files and how to
use these options.
See hg help dates for a list of formats valid for -d/--date.
Examples:
o import a traditional patch from a website and detect renames:
hg import -s 80 http://example.com/bugfix.patch
o import a changeset from an hgweb server:
hg import https://www.mercurial-scm.org/repo/hg/rev/5ca8c111e9aa
o import all the patches in an Unix-style mbox:
hg import incoming-patches.mbox
o import patches from stdin:
hg import -
o attempt to exactly restore an exported changeset (not always possible):
hg import --exact proposed-fix.patch
o use an external tool to apply a patch which is too fuzzy for the default internal tool.
hg import --config ui.patch="patch --merge" fuzzy.patch
o change the default fuzzing from 2 to a less strict 7
hg import --config ui.fuzz=7 fuzz.patch
Returns 0 on success, 1 on partial success (see --partial).
Options:
-p,--strip <NUM>
directory strip option for patch. This has the same meaning as the corresponding
patch option (default: 1)
-b,--base <PATH>
base path (DEPRECATED)
--secret
use the secret phase for committing
-e, --edit
invoke editor on commit messages
-f, --force
skip check for outstanding uncommitted changes (DEPRECATED)
--no-commit
don't commit, just update the working directory
--bypass
apply patch without touching the working directory
--partial
commit even if some hunks fail
--exact
abort if patch would apply lossily
--prefix <DIR>
apply patch to subdirectory
--import-branch
use any branch information in patch (implied by --exact)
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
-s,--similarity <SIMILARITY>
guess renamed files by similarity (0<=s<=100)
aliases: patch
unbundle
apply one or more bundle files:
hg unbundle [-u] FILE...
Apply one or more bundle files generated by hg bundle.
Returns 0 on success, 1 if an update has unresolved files.
Options:
-u, --update
update to new branch head if changesets were unbundled
Repository maintenance
manifest
output the current or given revision of the project manifest:
hg manifest [-r REV]
Print a list of version controlled files for the given revision. If no revision is given,
the first parent of the working directory is used, or the null revision if no revision is
checked out.
With -v, print file permissions, symlink and executable bits. With --debug, print file
revision hashes.
If option --all is specified, the list of all files from all revisions is printed. This
includes deleted and renamed files.
Returns 0 on success.
Options:
-r,--rev <REV>
revision to display
--all list files from all revisions
-T,--template <TEMPLATE>
display with template
recover
roll back an interrupted transaction:
hg recover
Recover from an interrupted commit or pull.
This command tries to fix the repository status after an interrupted operation. It should
only be necessary when Mercurial suggests it.
Returns 0 if successful, 1 if nothing to recover or verify fails.
Options:
--verify
run hg verify after successful recover
rollback
roll back the last transaction (DANGEROUS) (DEPRECATED):
hg rollback
Please use hg commit --amend instead of rollback to correct mistakes in the last commit.
This command should be used with care. There is only one level of rollback, and there is
no way to undo a rollback. It will also restore the dirstate at the time of the last
transaction, losing any dirstate changes since that time. This command does not alter the
working directory.
Transactions are used to encapsulate the effects of all commands that create new change-
sets or propagate existing changesets into a repository.
For example, the following commands are transactional, and their effects can be rolled
back:
o commit
o import
o pull
o push (with this repository as the destination)
o unbundle
To avoid permanent data loss, rollback will refuse to rollback a commit transaction if it
isn't checked out. Use --force to override this protection.
The rollback command can be entirely disabled by setting the ui.rollback configuration
setting to false. If you're here because you want to use rollback and it's disabled, you
can re-enable the command by setting ui.rollback to true.
This command is not intended for use on public repositories. Once changes are visible for
pull by other users, rolling a transaction back locally is ineffective (someone else may
already have pulled the changes). Furthermore, a race is possible with readers of the
repository; for example an in-progress pull from the repository may fail if a rollback is
performed.
Returns 0 on success, 1 if no rollback data is available.
Options:
-n, --dry-run
do not perform actions, just print output
-f, --force
ignore safety measures
verify
verify the integrity of the repository:
hg verify
Verify the integrity of the current repository.
This will perform an extensive check of the repository's integrity, validating the hashes
and checksums of each entry in the changelog, manifest, and tracked files, as well as the
integrity of their crosslinks and indices.
Please see https://mercurial-scm.org/wiki/RepositoryCorruption for more information about
recovery from corruption of the repository.
Returns 0 on success, 1 if errors are encountered.
Options:
--full perform more checks (EXPERIMENTAL)

Uncategorized commands
BUNDLE FILE FORMATS
Mercurial supports generating standalone "bundle" files that hold repository data. These
"bundles" are typically saved locally and used later or exchanged between different repos-
itories, possibly on different machines. Example commands using bundles are hg bundle and
hg unbundle.
Generation of bundle files is controlled by a "bundle specification" ("bundlespec")
string. This string tells the bundle generation process how to create the bundle.
A "bundlespec" string is composed of the following elements:
type A string denoting the bundle format to use.
compression
Denotes the compression engine to use compressing the raw bundle data.
parameters
Arbitrary key-value parameters to further control bundle generation.
A "bundlespec" string has the following formats:
<type> The literal bundle format string is used.
<compression>-<type>
The compression engine and format are delimited by a hyphen (-).
Optional parameters follow the <type>. Parameters are URI escaped key=value pairs. Each
pair is delimited by a semicolon (;). The first parameter begins after a ; immediately
following the <type> value.
Available Types
The following bundle <type> strings are available:
v1 Produces a legacy "changegroup" version 1 bundle.
This format is compatible with nearly all Mercurial clients because it is the old-
est. However, it has some limitations, which is why it is no longer the default for
new repositories.
v1 bundles can be used with modern repositories using the "generaldelta" storage
format. However, it may take longer to produce the bundle and the resulting bundle
may be significantly larger than a v2 bundle.
v1 bundles can only use the gzip, bzip2, and none compression formats.
v2 Produces a version 2 bundle.
Version 2 bundles are an extensible format that can store additional repository
data (such as bookmarks and phases information) and they can store data more effi-
ciently, resulting in smaller bundles.
Version 2 bundles can also use modern compression engines, such as zstd, making
them faster to compress and often smaller.
Available Compression Engines
The following bundle <compression> engines can be used:
bzip2
An algorithm that produces smaller bundles than gzip.
All Mercurial clients should support this format.
This engine will likely produce smaller bundles than gzip but will be significantly
slower, both during compression and decompression.
If available, the zstd engine can yield similar or better compression at much
higher speeds.
gzip
zlib compression using the DEFLATE algorithm.
All Mercurial clients should support this format. The compression algorithm strikes
a reasonable balance between compression ratio and size.
none
No compression is performed.
Use this compression engine to explicitly disable compression.
Examples
v2
Produce a v2 bundle using default options, including compression.
none-v1
Produce a v1 bundle with no compression.
zstd-v2
Produce a v2 bundle with zstandard compression using default settings.
zstd-v1
This errors because zstd is not supported for v1 types.
COLORIZING OUTPUTS
Mercurial colorizes output from several commands.
For example, the diff command shows additions in green and deletions in red, while the
status command shows modified files in magenta. Many other commands have analogous colors.
It is possible to customize these colors.
To enable color (default) whenever possible use:
[ui]
color = yes
To disable color use:
[ui]
color = no
See hg help config.ui.color for details.
The default pager on Windows does not support color, so enabling the pager will effec-
tively disable color. See hg help config.ui.paginate to disable the pager. Alternately,
MSYS and Cygwin shells provide less as a pager, which can be configured to support ANSI
color mode. Windows 10 natively supports ANSI color mode.
Mode
Mercurial can use various systems to display color. The supported modes are ansi, win32,
and terminfo. See hg help config.color for details about how to control the mode.
Effects
Other effects in addition to color, like bold and underlined text, are also available. By
default, the terminfo database is used to find the terminal codes used to change color and
effect. If terminfo is not available, then effects are rendered with the ECMA-48 SGR con-
trol function (aka ANSI escape codes).
The available effects in terminfo mode are 'blink', 'bold', 'dim', 'inverse', 'invisible',
'italic', 'standout', and 'underline'; in ECMA-48 mode, the options are 'bold', 'inverse',
'italic', and 'underline'. How each is rendered depends on the terminal emulator. Some
may not be available for a given terminal type, and will be silently ignored.
If the terminfo entry for your terminal is missing codes for an effect or has the wrong
codes, you can add or override those codes in your configuration:
[color]
terminfo.dim = \E[2m
where 'E' is substituted with an escape character.
Labels
Text receives color effects depending on the labels that it has. Many default Mercurial
commands emit labelled text. You can also define your own labels in templates using the
label function, see hg help templates. A single portion of text may have more than one la-
bel. In that case, effects given to the last label will override any other effects. This
includes the special "none" effect, which nullifies other effects.
Labels are normally invisible. In order to see these labels and their position in the
text, use the global --color=debug option. The same anchor text may be associated to mul-
tiple labels, e.g.
[log.changeset changeset.secret|changeset: 22611:6f0a53c8f587]
The following are the default effects for some default labels. Default effects may be
overridden from your configuration file:
[color]
status.modified = blue bold underline red_background
status.added = green bold
status.removed = red bold blue_background
status.deleted = cyan bold underline
status.unknown = magenta bold underline
status.ignored = black bold
# 'none' turns off all effects
status.clean = none
status.copied = none
qseries.applied = blue bold underline
qseries.unapplied = black bold
qseries.missing = red bold
diff.diffline = bold
diff.extended = cyan bold
diff.file_a = red bold
diff.file_b = green bold
diff.hunk = magenta
diff.deleted = red
diff.inserted = green
diff.changed = white
diff.tab =
diff.trailingwhitespace = bold red_background
# Blank so it inherits the style of the surrounding label
changeset.public =
changeset.draft =
changeset.secret =
resolve.unresolved = red bold
resolve.resolved = green bold
bookmarks.active = green
branches.active = none
branches.closed = black bold
branches.current = green
branches.inactive = none
tags.normal = green
tags.local = black bold
rebase.rebased = blue
rebase.remaining = red bold
shelve.age = cyan
shelve.newest = green bold
shelve.name = blue bold
histedit.remaining = red bold
Custom colors
Because there are only eight standard colors, Mercurial allows you to define color names
for other color slots which might be available for your terminal type, assuming terminfo
mode. For instance:
color.brightblue = 12
color.pink = 207
color.orange = 202
to set 'brightblue' to color slot 12 (useful for 16 color terminals that have brighter
colors defined in the upper eight) and, 'pink' and 'orange' to colors in 256-color xterm's
default color cube. These defined colors may then be used as any of the pre-defined
eight, including appending '_background' to set the background to that color.
DATE FORMATS
Some commands allow the user to specify a date, e.g.:
o backout, commit, import, tag: Specify the commit date.
o log, revert, update: Select revision(s) by date.
Many date formats are valid. Here are some examples:
o Wed Dec 6 13:18:29 2006 (local timezone assumed)
o Dec 6 13:18 -0600 (year assumed, time offset provided)
o Dec 6 13:18 UTC (UTC and GMT are aliases for +0000)
o Dec 6 (midnight)
o 13:18 (today assumed)
o 3:39 (3:39AM assumed)
o 3:39pm (15:39)
o 2006-12-06 13:18:29 (ISO 8601 format)
o 2006-12-6 13:18
o 2006-12-6
o 12-6
o 12/6
o 12/6/6 (Dec 6 2006)
o today (midnight)
o yesterday (midnight)
o now - right now
Lastly, there is Mercurial's internal format:
o 1165411109 0 (Wed Dec 6 13:18:29 2006 UTC)
This is the internal representation format for dates. The first number is the number of
seconds since the epoch (1970-01-01 00:00 UTC). The second is the offset of the local
timezone, in seconds west of UTC (negative if the timezone is east of UTC).
The log command also accepts date ranges:
o <DATE - at or before a given date/time
o >DATE - on or after a given date/time
o DATE to DATE - a date range, inclusive
o -DAYS - within a given number of days from today
DEPRECATED FEATURES
Mercurial evolves over time, some features, options, commands may be replaced by better
and more secure alternatives. This topic will help you migrating your existing usage
and/or configuration to newer features.
Commands
The following commands are still available but their use are not recommended:
locate
This command has been replaced by hg files.
parents
This command can be replaced by hg summary or hg log with appropriate revsets. See hg help
revsets for more information.
tip
The recommended alternative is hg heads.
Options
web.allowpull
Renamed to allow-pull.
web.allow_push
Renamed to allow-push.
DIFF FORMATS
Mercurial's default format for showing changes between two versions of a file is compati-
ble with the unified format of GNU diff, which can be used by GNU patch and many other
standard tools.
While this standard format is often enough, it does not encode the following information:
o executable status and other permission bits
o copy or rename information
o changes in binary files
o creation or deletion of empty files
Mercurial also supports the extended diff format from the git VCS which addresses these
limitations. The git diff format is not produced by default because a few widespread tools
still do not understand this format.
This means that when generating diffs from a Mercurial repository (e.g. with hg export),
you should be careful about things like file copies and renames or other things mentioned
above, because when applying a standard diff to a different repository, this extra infor-
mation is lost. Mercurial's internal operations (like push and pull) are not affected by
this, because they use an internal binary format for communicating changes.
To make Mercurial produce the git extended diff format, use the --git option available for
many commands, or set 'git = True' in the [diff] section of your configuration file. You
do not need to set this option when importing diffs in this format or using them in the mq
extension.
ENVIRONMENT VARIABLES
HG Path to the 'hg' executable, automatically passed when running hooks, extensions or
external tools. If unset or empty, this is the hg executable's name if it's frozen,
or an executable named 'hg' (with %PATHEXT% [defaulting to COM/EXE/BAT/CMD] exten-
sions on Windows) is searched.
HGEDITOR
This is the name of the editor to run when committing. See EDITOR.
(deprecated, see hg help config.ui.editor)
HGENCODING
This overrides the default locale setting detected by Mercurial. This setting is
used to convert data including usernames, changeset descriptions, tag names, and
branches. This setting can be overridden with the --encoding command-line option.
HGENCODINGMODE
This sets Mercurial's behavior for handling unknown characters while transcoding
user input. The default is "strict", which causes Mercurial to abort if it can't
map a character. Other settings include "replace", which replaces unknown charac-
ters, and "ignore", which drops them. This setting can be overridden with the --en-
codingmode command-line option.
HGENCODINGAMBIGUOUS
This sets Mercurial's behavior for handling characters with "ambiguous" widths like
accented Latin characters with East Asian fonts. By default, Mercurial assumes am-
biguous characters are narrow, set this variable to "wide" if such characters cause
formatting problems.
HGMERGE
An executable to use for resolving merge conflicts. The program will be executed
with three arguments: local file, remote file, ancestor file.
(deprecated, see hg help config.ui.merge)
HGRCPATH
A list of files or directories to search for configuration files. Item separator is
":" on Unix, ";" on Windows. If HGRCPATH is not set, platform default search path
is used. If empty, only the .hg/hgrc from the current repository is read.
For each element in HGRCPATH:
o if it's a directory, all files ending with .rc are added
o otherwise, the file itself will be added
HGRCSKIPREPO
When set, the .hg/hgrc from repositories are not read.
HGPLAIN
When set, this disables any configuration settings that might change Mercurial's
default output. This includes encoding, defaults, verbose mode, debug mode, quiet
mode, tracebacks, and localization. This can be useful when scripting against Mer-
curial in the face of existing user configuration.
In addition to the features disabled by HGPLAIN=, the following values can be spec-
ified to adjust behavior:
+strictflags
Restrict parsing of command line flags.
Equivalent options set via command line flags or environment variables are not
overridden.
See hg help scripting for details.
HGPLAINEXCEPT
This is a comma-separated list of features to preserve when HGPLAIN is enabled.
Currently the following values are supported:
alias
Don't remove aliases.
color
Don't disable colored output.
i18n
Preserve internationalization.
revsetalias
Don't remove revset aliases.
templatealias
Don't remove template aliases.
progress
Don't hide progress output.
Setting HGPLAINEXCEPT to anything (even an empty string) will enable plain mode.
HGUSER This is the string used as the author of a commit. If not set, available values
will be considered in this order:
o HGUSER (deprecated)
o configuration files from the HGRCPATH
o EMAIL
o interactive prompt
o LOGNAME (with @hostname appended)
(deprecated, see hg help config.ui.username)
EMAIL May be used as the author of a commit; see HGUSER.
LOGNAME
May be used as the author of a commit; see HGUSER.
VISUAL This is the name of the editor to use when committing. See EDITOR.
EDITOR Sometimes Mercurial needs to open a text file in an editor for a user to modify,
for example when writing commit messages. The editor it uses is determined by look-
ing at the environment variables HGEDITOR, VISUAL and EDITOR, in that order. The
first non-empty one is chosen. If all of them are empty, the editor defaults to
'vi'.
PYTHONPATH
This is used by Python to find imported modules and may need to be set appropri-
ately if this Mercurial is not installed system-wide.
SAFELY REWRITING HISTORY (EXPERIMENTAL)
Obsolescence markers make it possible to mark changesets that have been deleted or super-
seded in a new version of the changeset.
Unlike the previous way of handling such changes, by stripping the old changesets from the
repository, obsolescence markers can be propagated between repositories. This allows for a
safe and simple way of exchanging mutable history and altering it after the fact. Change-
set phases are respected, such that only draft and secret changesets can be altered (see
hg help phases for details).
Obsolescence is tracked using "obsolescence markers", a piece of metadata tracking which
changesets have been made obsolete, potential successors for a given changeset, the moment
the changeset was marked as obsolete, and the user who performed the rewriting operation.
The markers are stored separately from standard changeset data can be exchanged without
any of the precursor changesets, preventing unnecessary exchange of obsolescence data.
The complete set of obsolescence markers describes a history of changeset modifications
that is orthogonal to the repository history of file modifications. This changeset history
allows for detection and automatic resolution of edge cases arising from multiple users
rewriting the same part of history concurrently.
Current feature status
This feature is still in development.
Instability
Rewriting changesets might introduce instability.
There are two main kinds of instability: orphaning and diverging.
Orphans are changesets left behind when their ancestors are rewritten. Divergence has two
variants:
o Content-divergence occurs when independent rewrites of the same changesets lead to dif-
ferent results.
o Phase-divergence occurs when the old (obsolete) version of a changeset becomes public.
It is possible to prevent local creation of orphans by using the following config:
[experimental]
evolution.createmarkers = true
evolution.exchange = true
You can also enable that option explicitly:
[experimental]
evolution.createmarkers = true
evolution.exchange = true
evolution.allowunstable = true
USING ADDITIONAL FEATURES
Mercurial has the ability to add new features through the use of extensions. Extensions
may add new commands, add options to existing commands, change the default behavior of
commands, or implement hooks.
To enable the "foo" extension, either shipped with Mercurial or in the Python search path,
create an entry for it in your configuration file, like this:
[extensions]
foo =
You may also specify the full path to an extension:
[extensions]
myfeature = ~/.hgext/myfeature.py
See hg help config for more information on configuration files.
Extensions are not loaded by default for a variety of reasons: they can increase startup
overhead; they may be meant for advanced usage only; they may provide potentially danger-
ous abilities (such as letting you destroy or modify history); they might not be ready for
prime time; or they may alter some usual behaviors of stock Mercurial. It is thus up to
the user to activate extensions as needed.
To explicitly disable an extension enabled in a configuration file of broader scope,
prepend its path with !:
[extensions]
# disabling extension bar residing in /path/to/extension/bar.py
bar = !/path/to/extension/bar.py
# ditto, but no path was supplied for extension baz
baz = !

SPECIFYING FILE SETS
Mercurial supports a functional language for selecting a set of files.
Like other file patterns, this pattern type is indicated by a prefix, 'set:'. The language
supports a number of predicates which are joined by infix operators. Parenthesis can be
used for grouping.
Identifiers such as filenames or patterns must be quoted with single or double quotes if
they contain characters outside of [.*{}[]?/\_a-zA-Z0-9\x80-\xff] or if they match one of
the predefined predicates. This generally applies to file patterns other than globs and
arguments for predicates. Pattern prefixes such as path: may be specified without quoting.
Special characters can be used in quoted identifiers by escaping them, e.g., \n is inter-
preted as a newline. To prevent them from being interpreted, strings can be prefixed with
r, e.g. r'...'.
See also hg help patterns.
Operators
There is a single prefix operator:
not x
Files not in x. Short form is ! x.
These are the supported infix operators:
x and y
The intersection of files in x and y. Short form is x & y.
x or y
The union of files in x and y. There are two alternative short forms: x | y and x +
y.
x - y
Files in x but not in y.
Predicates
The following predicates are supported:
added()
File that is added according to hg status.
binary()
File that appears to be binary (contains NUL bytes).
clean()
File that is clean according to hg status.
copied()
File that is recorded as being copied.
deleted()
Alias for missing().
encoding(name)
File can be successfully decoded with the given character encoding. May not be use-
ful for encodings other than ASCII and UTF-8.
eol(style)
File contains newlines of the given style (dos, unix, mac). Binary files are ex-
cluded, files with mixed line endings match multiple styles.
exec()
File that is marked as executable.
grep(regex)
File contains the given regular expression.
hgignore()
File that matches the active .hgignore pattern.
ignored()
File that is ignored according to hg status.
missing()
File that is missing according to hg status.
modified()
File that is modified according to hg status.
portable()
File that has a portable name. (This doesn't include filenames with case colli-
sions.)
removed()
File that is removed according to hg status.
resolved()
File that is marked resolved according to hg resolve -l.
revs(revs, pattern)
Evaluate set in the specified revisions. If the revset match multiple revs, this
will return file matching pattern in any of the revision.
size(expression)
File size matches the given expression. Examples:
o size('1k') - files from 1024 to 2047 bytes
o size('< 20k') - files less than 20480 bytes
o size('>= .5MB') - files at least 524288 bytes
o size('4k - 1MB') - files from 4096 bytes to 1048576 bytes
status(base, rev, pattern)
Evaluate predicate using status change between base and rev. Examples:
o status(3, 7, added()) - matches files added from "3" to "7"
subrepo([pattern])
Subrepositories whose paths match the given pattern.
symlink()
File that is marked as a symlink.
tracked()
File that is under Mercurial control.
unknown()
File that is unknown according to hg status.
unresolved()
File that is marked unresolved according to hg resolve -l.
Examples
Some sample queries:
o Show status of files that appear to be binary in the working directory:
hg status -A "set:binary()"
o Forget files that are in .hgignore but are already tracked:
hg forget "set:hgignore() and not ignored()"
o Find text files that contain a string:
hg files "set:grep(magic) and not binary()"
o Find C files in a non-standard encoding:
hg files "set:**.c and not encoding('UTF-8')"
o Revert copies of large binary files:
hg revert "set:copied() and binary() and size('>1M')"
o Revert files that were added to the working directory:
hg revert "set:revs('wdir()', added())"
o Remove files listed in foo.lst that contain the letter a or b:
hg remove "set: listfile:foo.lst and (**a* or **b*)"
COMMAND-LINE FLAGS
Most Mercurial commands accept various flags.
Flag names
Flags for each command are listed in hg help for that command. Additionally, some flags,
such as --repository, are global and can be used with any command - those are seen in hg
help -v, and can be specified before or after the command.
Every flag has at least a long name, such as --repository. Some flags may also have a
short one-letter name, such as the equivalent -R. Using the short or long name is equiva-
lent and has the same effect. The long name may be abbreviated to any unambiguous prefix.
For example, hg commit --amend can be abbreviated to hg commit --am.
Flags that have a short name can also be bundled together - for instance, to specify both
--edit (short -e) and --interactive (short -i), one could use:
hg commit -ei
If any of the bundled flags takes a value (i.e. is not a boolean), it must be last, fol-
lowed by the value:
hg commit -im 'Message'
Flag types
Mercurial command-line flags can be strings, numbers, booleans, or lists of strings.
Specifying flag values
The following syntaxes are allowed, assuming a flag 'flagname' with short name 'f':
--flagname=foo
--flagname foo
-f foo
-ffoo
This syntax applies to all non-boolean flags (strings, numbers or lists).
Specifying boolean flags
Boolean flags do not take a value parameter. To specify a boolean, use the flag name to
set it to true, or the same name prefixed with 'no-' to set it to false:
hg commit --interactive
hg commit --no-interactive
Specifying list flags
List flags take multiple values. To specify them, pass the flag multiple times:
hg files --include mercurial --include tests
Setting flag defaults
In order to set a default value for a flag in an hgrc file, it is recommended to use
aliases:
[alias]
commit = commit --interactive
For more information on hgrc files, see hg help config.
Overriding flags on the command line
If the same non-list flag is specified multiple times on the command line, the latest
specification is used:
hg commit -m "Ignored value" -m "Used value"
This includes the use of aliases - e.g., if one has:
[alias]
committemp = commit -m "Ignored value"
then the following command will override that -m:
hg committemp -m "Used value"
Overriding flag defaults
Every flag has a default value, and you may also set your own defaults in hgrc as de-
scribed above. Except for list flags, defaults can be overridden on the command line sim-
ply by specifying the flag in that location.
Hidden flags
Some flags are not shown in a command's help by default - specifically, those that are
deemed to be experimental, deprecated or advanced. To show all flags, add the --verbose
flag for the help command:
hg help --verbose commit
GLOSSARY
Ancestor
Any changeset that can be reached by an unbroken chain of parent changesets from a
given changeset. More precisely, the ancestors of a changeset can be defined by two
properties: a parent of a changeset is an ancestor, and a parent of an ancestor is
an ancestor. See also: 'Descendant'.
Bookmark
Bookmarks are pointers to certain commits that move when committing. They are simi-
lar to tags in that it is possible to use bookmark names in all places where Mercu-
rial expects a changeset ID, e.g., with hg update. Unlike tags, bookmarks move
along when you make a commit.
Bookmarks can be renamed, copied and deleted. Bookmarks are local, unless they are
explicitly pushed or pulled between repositories. Pushing and pulling bookmarks
allow you to collaborate with others on a branch without creating a named branch.
Branch (Noun) A child changeset that has been created from a parent that is not a head.
These are known as topological branches, see 'Branch, topological'. If a topologi-
cal branch is named, it becomes a named branch. If a topological branch is not
named, it becomes an anonymous branch. See 'Branch, anonymous' and 'Branch, named'.
Branches may be created when changes are pulled from or pushed to a remote reposi-
tory, since new heads may be created by these operations. Note that the term branch
can also be used informally to describe a development process in which certain de-
velopment is done independently of other development. This is sometimes done ex-
plicitly with a named branch, but it can also be done locally, using bookmarks or
clones and anonymous branches.
Example: "The experimental branch."
(Verb) The action of creating a child changeset which results in its parent having
more than one child.
Example: "I'm going to branch at X."
Branch, anonymous
Every time a new child changeset is created from a parent that is not a head and
the name of the branch is not changed, a new anonymous branch is created.
Branch, closed
A named branch whose branch heads have all been closed.
Branch, default
The branch assigned to a changeset when no name has previously been assigned.
Branch head
See 'Head, branch'.
Branch, inactive
If a named branch has no topological heads, it is considered to be inactive. As an
example, a feature branch becomes inactive when it is merged into the default
branch. The hg branches command shows inactive branches by default, though they can
be hidden with hg branches --active.
NOTE: this concept is deprecated because it is too implicit. Branches should now
be explicitly closed using hg commit --close-branch when they are no longer needed.
Branch, named
A collection of changesets which have the same branch name. By default, children of
a changeset in a named branch belong to the same named branch. A child can be ex-
plicitly assigned to a different branch. See hg help branch, hg help branches and
hg commit --close-branch for more information on managing branches.
Named branches can be thought of as a kind of namespace, dividing the collection of
changesets that comprise the repository into a collection of disjoint subsets. A
named branch is not necessarily a topological branch. If a new named branch is cre-
ated from the head of another named branch, or the default branch, but no further
changesets are added to that previous branch, then that previous branch will be a
branch in name only.
Branch tip
See 'Tip, branch'.
Branch, topological
Every time a new child changeset is created from a parent that is not a head, a new
topological branch is created. If a topological branch is named, it becomes a named
branch. If a topological branch is not named, it becomes an anonymous branch of the
current, possibly default, branch.
Changelog
A record of the changesets in the order in which they were added to the repository.
This includes details such as changeset id, author, commit message, date, and list
of changed files.
Changeset
A snapshot of the state of the repository used to record a change.
Changeset, child
The converse of parent changeset: if P is a parent of C, then C is a child of P.
There is no limit to the number of children that a changeset may have.
Changeset id
A SHA-1 hash that uniquely identifies a changeset. It may be represented as either
a "long" 40 hexadecimal digit string, or a "short" 12 hexadecimal digit string.
Changeset, merge
A changeset with two parents. This occurs when a merge is committed.
Changeset, parent
A revision upon which a child changeset is based. Specifically, a parent changeset
of a changeset C is a changeset whose node immediately precedes C in the DAG.
Changesets have at most two parents.
Checkout
(Noun) The working directory being updated to a specific revision. This use should
probably be avoided where possible, as changeset is much more appropriate than
checkout in this context.
Example: "I'm using checkout X."
(Verb) Updating the working directory to a specific changeset. See hg help update.
Example: "I'm going to check out changeset X."
Child changeset
See 'Changeset, child'.
Close changeset
See 'Head, closed branch'.
Closed branch
See 'Branch, closed'.
Clone (Noun) An entire or partial copy of a repository. The partial clone must be in the
form of a revision and its ancestors.
Example: "Is your clone up to date?"
(Verb) The process of creating a clone, using hg clone.
Example: "I'm going to clone the repository."
Closed branch head
See 'Head, closed branch'.
Commit (Noun) A synonym for changeset.
Example: "Is the bug fixed in your recent commit?"
(Verb) The act of recording changes to a repository. When files are committed in a
working directory, Mercurial finds the differences between the committed files and
their parent changeset, creating a new changeset in the repository.
Example: "You should commit those changes now."
Cset A common abbreviation of the term changeset.
DAG The repository of changesets of a distributed version control system (DVCS) can be
described as a directed acyclic graph (DAG), consisting of nodes and edges, where
nodes correspond to changesets and edges imply a parent -> child relation. This
graph can be visualized by graphical tools such as hg log --graph. In Mercurial,
the DAG is limited by the requirement for children to have at most two parents.
Deprecated
Feature removed from documentation, but not scheduled for removal.
Default branch
See 'Branch, default'.
Descendant
Any changeset that can be reached by a chain of child changesets from a given
changeset. More precisely, the descendants of a changeset can be defined by two
properties: the child of a changeset is a descendant, and the child of a descendant
is a descendant. See also: 'Ancestor'.
Diff (Noun) The difference between the contents and attributes of files in two change-
sets or a changeset and the current working directory. The difference is usually
represented in a standard form called a "diff" or "patch". The "git diff" format is
used when the changes include copies, renames, or changes to file attributes, none
of which can be represented/handled by classic "diff" and "patch".
Example: "Did you see my correction in the diff?"
(Verb) Diffing two changesets is the action of creating a diff or patch.
Example: "If you diff with changeset X, you will see what I mean."
Directory, working
The working directory represents the state of the files tracked by Mercurial, that
will be recorded in the next commit. The working directory initially corresponds to
the snapshot at an existing changeset, known as the parent of the working direc-
tory. See 'Parent, working directory'. The state may be modified by changes to the
files introduced manually or by a merge. The repository metadata exists in the .hg
directory inside the working directory.
Draft Changesets in the draft phase have not been shared with publishing repositories and
may thus be safely changed by history-modifying extensions. See hg help phases.
Experimental
Feature that may change or be removed at a later date.
Graph See DAG and hg log --graph.
Head The term 'head' may be used to refer to both a branch head or a repository head,
depending on the context. See 'Head, branch' and 'Head, repository' for specific
definitions.
Heads are where development generally takes place and are the usual targets for up-
date and merge operations.
Head, branch
A changeset with no descendants on the same named branch.
Head, closed branch
A changeset that marks a head as no longer interesting. The closed head is no
longer listed by hg heads. A branch is considered closed when all its heads are
closed and consequently is not listed by hg branches.
Closed heads can be re-opened by committing new changeset as the child of the
changeset that marks a head as closed.
Head, repository
A topological head which has not been closed.
Head, topological
A changeset with no children in the repository.
History, immutable
Once committed, changesets cannot be altered. Extensions which appear to change
history actually create new changesets that replace existing ones, and then destroy
the old changesets. Doing so in public repositories can result in old changesets
being reintroduced to the repository.
History, rewriting
The changesets in a repository are immutable. However, extensions to Mercurial can
be used to alter the repository, usually in such a way as to preserve changeset
contents.
Immutable history
See 'History, immutable'.
Merge changeset
See 'Changeset, merge'.
Manifest
Each changeset has a manifest, which is the list of files that are tracked by the
changeset.
Merge Used to bring together divergent branches of work. When you update to a changeset
and then merge another changeset, you bring the history of the latter changeset
into your working directory. Once conflicts are resolved (and marked), this merge
may be committed as a merge changeset, bringing two branches together in the DAG.
Named branch
See 'Branch, named'.
Null changeset
The empty changeset. It is the parent state of newly-initialized repositories and
repositories with no checked out revision. It is thus the parent of root changesets
and the effective ancestor when merging unrelated changesets. Can be specified by
the alias 'null' or by the changeset ID '000000000000'.
Parent See 'Changeset, parent'.
Parent changeset
See 'Changeset, parent'.
Parent, working directory
The working directory parent reflects a virtual revision which is the child of the
changeset (or two changesets with an uncommitted merge) shown by hg parents. This
is changed with hg update. Other commands to see the working directory parent are
hg summary and hg id. Can be specified by the alias ".".
Patch (Noun) The product of a diff operation.
Example: "I've sent you my patch."
(Verb) The process of using a patch file to transform one changeset into another.
Example: "You will need to patch that revision."
Phase A per-changeset state tracking how the changeset has been or should be shared. See
hg help phases.
Public Changesets in the public phase have been shared with publishing repositories and
are therefore considered immutable. See hg help phases.
Pull An operation in which changesets in a remote repository which are not in the local
repository are brought into the local repository. Note that this operation without
special arguments only updates the repository, it does not update the files in the
working directory. See hg help pull.
Push An operation in which changesets in a local repository which are not in a remote
repository are sent to the remote repository. Note that this operation only adds
changesets which have been committed locally to the remote repository. Uncommitted
changes are not sent. See hg help push.
Repository
The metadata describing all recorded states of a collection of files. Each recorded
state is represented by a changeset. A repository is usually (but not always) found
in the .hg subdirectory of a working directory. Any recorded state can be recreated
by "updating" a working directory to a specific changeset.
Repository head
See 'Head, repository'.
Revision
A state of the repository at some point in time. Earlier revisions can be updated
to by using hg update. See also 'Revision number'; See also 'Changeset'.
Revision number
This integer uniquely identifies a changeset in a specific repository. It repre-
sents the order in which changesets were added to a repository, starting with revi-
sion number 0. Note that the revision number may be different in each clone of a
repository. To identify changesets uniquely between different clones, see 'Change-
set id'.
Revlog History storage mechanism used by Mercurial. It is a form of delta encoding, with
occasional full revision of data followed by delta of each successive revision. It
includes data and an index pointing to the data.
Rewriting history
See 'History, rewriting'.
Root A changeset that has only the null changeset as its parent. Most repositories have
only a single root changeset.
Secret Changesets in the secret phase may not be shared via push, pull, or clone. See hg
help phases.
Tag An alternative name given to a changeset. Tags can be used in all places where Mer-
curial expects a changeset ID, e.g., with hg update. The creation of a tag is
stored in the history and will thus automatically be shared with other using push
and pull.
Tip The changeset with the highest revision number. It is the changeset most recently
added in a repository.
Tip, branch
The head of a given branch with the highest revision number. When a branch name is
used as a revision identifier, it refers to the branch tip. See also 'Branch,
head'. Note that because revision numbers may be different in different repository
clones, the branch tip may be different in different cloned repositories.
Update (Noun) Another synonym of changeset.
Example: "I've pushed an update."
(Verb) This term is usually used to describe updating the state of the working di-
rectory to that of a specific changeset. See hg help update.
Example: "You should update."
Working directory
See 'Directory, working'.
Working directory parent
See 'Parent, working directory'.
SYNTAX FOR MERCURIAL IGNORE FILES
Synopsis
The Mercurial system uses a file called .hgignore in the root directory of a repository to
control its behavior when it searches for files that it is not currently tracking.
Description
The working directory of a Mercurial repository will often contain files that should not
be tracked by Mercurial. These include backup files created by editors and build products
created by compilers. These files can be ignored by listing them in a .hgignore file in
the root of the working directory. The .hgignore file must be created manually. It is typ-
ically put under version control, so that the settings will propagate to other reposito-
ries with push and pull.
An untracked file is ignored if its path relative to the repository root directory, or any
prefix path of that path, is matched against any pattern in .hgignore.
For example, say we have an untracked file, file.c, at a/b/file.c inside our repository.
Mercurial will ignore file.c if any pattern in .hgignore matches a/b/file.c, a/b or a.
In addition, a Mercurial configuration file can reference a set of per-user or global ig-
nore files. See the ignore configuration key on the [ui] section of hg help config for de-
tails of how to configure these files.
To control Mercurial's handling of files that it manages, many commands support the -I and
-X options; see hg help <command> and hg help patterns for details.
Files that are already tracked are not affected by .hgignore, even if they appear in
.hgignore. An untracked file X can be explicitly added with hg add X, even if X would be
excluded by a pattern in .hgignore.
Syntax
An ignore file is a plain text file consisting of a list of patterns, with one pattern per
line. Empty lines are skipped. The # character is treated as a comment character, and the
\ character is treated as an escape character.
Mercurial supports several pattern syntaxes. The default syntax used is Python/Perl-style
regular expressions.
To change the syntax used, use a line of the following form:
syntax: NAME
where NAME is one of the following:
regexp
Regular expression, Python/Perl syntax.
glob
Shell-style glob.
rootglob
A variant of glob that is rooted (see below).
The chosen syntax stays in effect when parsing all patterns that follow, until another
syntax is selected.
Neither glob nor regexp patterns are rooted. A glob-syntax pattern of the form *.c will
match a file ending in .c in any directory, and a regexp pattern of the form \.c$ will do
the same. To root a regexp pattern, start it with ^. To get the same effect with glob-syn-
tax, you have to use rootglob.
Subdirectories can have their own .hgignore settings by adding subinclude:path/to/sub-
dir/.hgignore to the root .hgignore. See hg help patterns for details on subinclude: and
include:.
Note Patterns specified in other than .hgignore are always rooted. Please see hg help
patterns for details.
Example
Here is an example ignore file.
# use glob syntax.
syntax: glob
*.elc
*.pyc
*~
# switch to regexp syntax.
syntax: regexp
^\.pc/
Debugging
Use the debugignore command to see if and why a file is ignored, or to see the combined
ignore pattern. See hg help debugignore for details.
CONFIGURING HGWEB
Mercurial's internal web server, hgweb, can serve either a single repository, or a tree of
repositories. In the second case, repository paths and global options can be defined using
a dedicated configuration file common to hg serve, hgweb.wsgi, hgweb.cgi and hgweb.fcgi.
This file uses the same syntax as other Mercurial configuration files but recognizes only
the following sections:
o web
o paths
o collections
The web options are thoroughly described in hg help config.
The paths section maps URL paths to paths of repositories in the filesystem. hgweb will
not expose the filesystem directly - only Mercurial repositories can be published and only
according to the configuration.
The left hand side is the path in the URL. Note that hgweb reserves subpaths like rev or
file, try using different names for nested repositories to avoid confusing effects.
The right hand side is the path in the filesystem. If the specified path ends with * or **
the filesystem will be searched recursively for repositories below that point. With * it
will not recurse into the repositories it finds (except for .hg/patches). With ** it will
also search inside repository working directories and possibly find subrepositories.
In this example:
[paths]
/projects/a = /srv/tmprepos/a
/projects/b = c:/repos/b
/ = /srv/repos/*
/user/bob = /home/bob/repos/**
o The first two entries make two repositories in different directories appear under the
same directory in the web interface
o The third entry will publish every Mercurial repository found in /srv/repos/, for in-
stance the repository /srv/repos/quux/ will appear as http://server/quux/
o The fourth entry will publish both http://server/user/bob/quux/ and
http://server/user/bob/quux/testsubrepo/
The collections section is deprecated and has been superseded by paths.
URLs and Common Arguments
URLs under each repository have the form /{command}[/{arguments}] where {command} repre-
sents the name of a command or handler and {arguments} represents any number of additional
URL parameters to that command.
The web server has a default style associated with it. Styles map to a collection of named
templates. Each template is used to render a specific piece of data, such as a changeset
or diff.
The style for the current request can be overridden two ways. First, if {command} contains
a hyphen (-), the text before the hyphen defines the style. For example, /atom-log will
render the log command handler with the atom style. The second way to set the style is
with the style query string argument. For example, /log?style=atom. The hyphenated URL pa-
rameter is preferred.
Not all templates are available for all styles. Attempting to use a style that doesn't
have all templates defined may result in an error rendering the page.
Many commands take a {revision} URL parameter. This defines the changeset to operate on.
This is commonly specified as the short, 12 digit hexadecimal abbreviation for the full 40
character unique revision identifier. However, any value described by hg help revisions
typically works.
Commands and URLs
The following web commands and their URLs are available:
/annotate/{revision}/{path}
Show changeset information for each line in a file.
The ignorews, ignorewsamount, ignorewseol, and ignoreblanklines query string arguments
have the same meaning as their [annotate] config equivalents. It uses the hgrc boolean
parsing logic to interpret the value. e.g. 0 and false are false and 1 and true are true.
If not defined, the server default settings are used.
The fileannotate template is rendered.
/archive/{revision}.{format}[/{path}]
Obtain an archive of repository content.
The content and type of the archive is defined by a URL path parameter. format is the
file extension of the archive type to be generated. e.g. zip or tar.bz2. Not all archive
types may be allowed by your server configuration.
The optional path URL parameter controls content to include in the archive. If omitted,
every file in the specified revision is present in the archive. If included, only the
specified file or contents of the specified directory will be included in the archive.
No template is used for this handler. Raw, binary content is generated.
/bookmarks
Show information about bookmarks.
No arguments are accepted.
The bookmarks template is rendered.
/branches
Show information about branches.
All known branches are contained in the output, even closed branches.
No arguments are accepted.
The branches template is rendered.
/changelog[/{revision}]
Show information about multiple changesets.
If the optional revision URL argument is absent, information about all changesets starting
at tip will be rendered. If the revision argument is present, changesets will be shown
starting from the specified revision.
If revision is absent, the rev query string argument may be defined. This will perform a
search for changesets.
The argument for rev can be a single revision, a revision set, or a literal keyword to
search for in changeset data (equivalent to hg log -k).
The revcount query string argument defines the maximum numbers of changesets to render.
For non-searches, the changelog template will be rendered.
/changeset[/{revision}]
Show information about a single changeset.
A URL path argument is the changeset identifier to show. See hg help revisions for possi-
ble values. If not defined, the tip changeset will be shown.
The changeset template is rendered. Contents of the changesettag, changesetbookmark,
filenodelink, filenolink, and the many templates related to diffs may all be used to pro-
duce the output.
/comparison/{revision}/{path}
Show a comparison between the old and new versions of a file from changes made on a par-
ticular revision.
This is similar to the diff handler. However, this form features a split or side-by-side
diff rather than a unified diff.
The context query string argument can be used to control the lines of context in the diff.
The filecomparison template is rendered.
/diff/{revision}/{path}
Show how a file changed in a particular commit.
The filediff template is rendered.
This handler is registered under both the /diff and /filediff paths. /diff is used in mod-
ern code.
/file/{revision}[/{path}]
Show information about a directory or file in the repository.
Info about the path given as a URL parameter will be rendered.
If path is a directory, information about the entries in that directory will be rendered.
This form is equivalent to the manifest handler.
If path is a file, information about that file will be shown via the filerevision tem-
plate.
If path is not defined, information about the root directory will be rendered.
/diff/{revision}/{path}
Show how a file changed in a particular commit.
The filediff template is rendered.
This handler is registered under both the /diff and /filediff paths. /diff is used in mod-
ern code.
/filelog/{revision}/{path}
Show information about the history of a file in the repository.
The revcount query string argument can be defined to control the maximum number of entries
to show.
The filelog template will be rendered.
/graph[/{revision}]
Show information about the graphical topology of the repository.
Information rendered by this handler can be used to create visual representations of
repository topology.
The revision URL parameter controls the starting changeset. If it's absent, the default is
tip.
The revcount query string argument can define the number of changesets to show information
for.
The graphtop query string argument can specify the starting changeset for producing jsdata
variable that is used for rendering graph in JavaScript. By default it has the same value
as revision.
This handler will render the graph template.
/help[/{topic}]
Render help documentation.
This web command is roughly equivalent to hg help. If a topic is defined, that help topic
will be rendered. If not, an index of available help topics will be rendered.
The help template will be rendered when requesting help for a topic. helptopics will be
rendered for the index of help topics.
/log[/{revision}[/{path}]]
Show repository or file history.
For URLs of the form /log/{revision}, a list of changesets starting at the specified
changeset identifier is shown. If {revision} is not defined, the default is tip. This form
is equivalent to the changelog handler.
For URLs of the form /log/{revision}/{file}, the history for a specific file will be
shown. This form is equivalent to the filelog handler.
/manifest[/{revision}[/{path}]]
Show information about a directory.
If the URL path arguments are omitted, information about the root directory for the tip
changeset will be shown.
Because this handler can only show information for directories, it is recommended to use
the file handler instead, as it can handle both directories and files.
The manifest template will be rendered for this handler.
/changeset[/{revision}]
Show information about a single changeset.
A URL path argument is the changeset identifier to show. See hg help revisions for possi-
ble values. If not defined, the tip changeset will be shown.
The changeset template is rendered. Contents of the changesettag, changesetbookmark,
filenodelink, filenolink, and the many templates related to diffs may all be used to pro-
duce the output.
/shortlog
Show basic information about a set of changesets.
This accepts the same parameters as the changelog handler. The only difference is the
shortlog template will be rendered instead of the changelog template.
/summary
Show a summary of repository state.
Information about the latest changesets, bookmarks, tags, and branches is captured by this
handler.
The summary template is rendered.
/tags
Show information about tags.
No arguments are accepted.
The tags template is rendered.

MERGE TOOLS
To merge files Mercurial uses merge tools.
A merge tool combines two different versions of a file into a merged file. Merge tools are
given the two files and the greatest common ancestor of the two file versions, so they can
determine the changes made on both branches.
Merge tools are used both for hg resolve, hg merge, hg update, hg backout and in several
extensions.
Usually, the merge tool tries to automatically reconcile the files by combining all
non-overlapping changes that occurred separately in the two different evolutions of the
same initial base file. Furthermore, some interactive merge programs make it easier to
manually resolve conflicting merges, either in a graphical way, or by inserting some con-
flict markers. Mercurial does not include any interactive merge programs but relies on ex-
ternal tools for that.
Available merge tools
External merge tools and their properties are configured in the merge-tools configuration
section - see hgrc(5) - but they can often just be named by their executable.
A merge tool is generally usable if its executable can be found on the system and if it
can handle the merge. The executable is found if it is an absolute or relative executable
path or the name of an application in the executable search path. The tool is assumed to
be able to handle the merge if it can handle symlinks if the file is a symlink, if it can
handle binary files if the file is binary, and if a GUI is available if the tool requires
a GUI.
There are some internal merge tools which can be used. The internal merge tools are:
:dump
Creates three versions of the files to merge, containing the contents of local,
other and base. These files can then be used to perform a merge manually. If the
file to be merged is named a.txt, these files will accordingly be named a.txt.lo-
cal, a.txt.other and a.txt.base and they will be placed in the same directory as
a.txt.
This implies premerge. Therefore, files aren't dumped, if premerge runs success-
fully. Use :forcedump to forcibly write files out.
(actual capabilities: binary, symlink)
:fail
Rather than attempting to merge files that were modified on both branches, it marks
them as unresolved. The resolve command must be used to resolve these conflicts.
(actual capabilities: binary, symlink)
:forcedump
Creates three versions of the files as same as :dump, but omits premerge.
(actual capabilities: binary, symlink)
:local
Uses the local p1() version of files as the merged version.
(actual capabilities: binary, symlink)
:merge
Uses the internal non-interactive simple merge algorithm for merging files. It will
fail if there are any conflicts and leave markers in the partially merged file.
Markers will have two sections, one for each side of merge.
:merge-local
Like :merge, but resolve all conflicts non-interactively in favor of the local p1()
changes.
:merge-other
Like :merge, but resolve all conflicts non-interactively in favor of the other p2()
changes.
:merge3
Uses the internal non-interactive simple merge algorithm for merging files. It will
fail if there are any conflicts and leave markers in the partially merged file.
Marker will have three sections, one from each side of the merge and one for the
base content.
:mergediff
Uses the internal non-interactive simple merge algorithm for merging files. It will
fail if there are any conflicts and leave markers in the partially merged file. The
marker will have two sections, one with the content from one side of the merge, and
one with a diff from the base content to the content on the other side. (experimen-
tal)
:other
Uses the other p2() version of files as the merged version.
(actual capabilities: binary, symlink)
:prompt
Asks the user which of the local p1() or the other p2() version to keep as the
merged version.
(actual capabilities: binary, symlink)
:tagmerge
Uses the internal tag merge algorithm (experimental).
:union
Uses the internal non-interactive simple merge algorithm for merging files. It will
use both left and right sides for conflict regions. No markers are inserted.
Internal tools are always available and do not require a GUI but will by default not han-
dle symlinks or binary files. See next section for detail about "actual capabilities" de-
scribed above.
Choosing a merge tool
Mercurial uses these rules when deciding which merge tool to use:
1. If a tool has been specified with the --tool option to merge or resolve, it is used.
If it is the name of a tool in the merge-tools configuration, its configuration is
used. Otherwise the specified tool must be executable by the shell.
2. If the HGMERGE environment variable is present, its value is used and must be exe-
cutable by the shell.
3. If the filename of the file to be merged matches any of the patterns in the merge-pat-
terns configuration section, the first usable merge tool corresponding to a matching
pattern is used.
4. If ui.merge is set it will be considered next. If the value is not the name of a con-
figured tool, the specified value is used and must be executable by the shell. Other-
wise the named tool is used if it is usable.
5. If any usable merge tools are present in the merge-tools configuration section, the one
with the highest priority is used.
6. If a program named hgmerge can be found on the system, it is used - but it will by de-
fault not be used for symlinks and binary files.
7. If the file to be merged is not binary and is not a symlink, then internal :merge is
used.
8. Otherwise, :prompt is used.
For historical reason, Mercurial treats merge tools as below while examining rules above.
+-----------+----------------+--------+---------+
|step | specified via | binary | symlink |
+-----------+----------------+--------+---------+
| | --tool | o/o | o/o |
| 1. | | | |
+-----------+----------------+--------+---------+
| | HGMERGE | o/o | o/o |
| 2. | | | |
+-----------+----------------+--------+---------+
| | merge-patterns | o/o(*) | x/?(*) |
| 3. | | | |
+-----------+----------------+--------+---------+
| | ui.merge | x/?(*) | x/?(*) |
| 4. | | | |
+-----------+----------------+--------+---------+
Each capability column indicates Mercurial behavior for internal/external merge tools at
examining each rule.
o "o": "assume that a tool has capability"
o "x": "assume that a tool does not have capability"
o "?": "check actual capability of a tool"
If merge.strict-capability-check configuration is true, Mercurial checks capabilities of
merge tools strictly in (*) cases above (= each capability column becomes "?/?"). It is
false by default for backward compatibility.
Note After selecting a merge program, Mercurial will by default attempt to merge the
files using a simple merge algorithm first. Only if it doesn't succeed because of
conflicting changes will Mercurial actually execute the merge program. Whether to
use the simple merge algorithm first can be controlled by the premerge setting of
the merge tool. Premerge is enabled by default unless the file is binary or a sym-
link.
See the merge-tools and ui sections of hgrc(5) for details on the configuration of merge
tools.
PAGER SUPPORT
Some Mercurial commands can produce a lot of output, and Mercurial will attempt to use a
pager to make those commands more pleasant.
To set the pager that should be used, set the application variable:
[pager]
pager = less -FRX
If no pager is set in the user or repository configuration, Mercurial uses the environment
variable $PAGER. If $PAGER is not set, pager.pager from the default or system configura-
tion is used. If none of these are set, a default pager will be used, typically less on
Unix and more on Windows.
On Windows, more is not color aware, so using it effectively disables color. MSYS and
Cygwin shells provide less as a pager, which can be configured to support ANSI color
codes. See hg help config.color.pagermode to configure the color mode when invoking a
pager.
You can disable the pager for certain commands by adding them to the pager.ignore list:
[pager]
ignore = version, help, update
To ignore global commands like hg version or hg help, you have to specify them in your
user configuration file.
To control whether the pager is used at all for an individual command, you can use
--pager=<value>:
o use as needed: auto.
o require the pager: yes or on.
o suppress the pager: no or off (any unrecognized value will also work).
To globally turn off all attempts to use a pager, set:
[ui]
paginate = never
which will prevent the pager from running.
FILE NAME PATTERNS
Mercurial accepts several notations for identifying one or more files at a time.
By default, Mercurial treats filenames verbatim without pattern matching, relative to the
current working directory. Note that your system shell might perform pattern matching of
its own before passing filenames into Mercurial.
Alternate pattern notations must be specified explicitly.
Note Patterns specified in .hgignore are not rooted. Please see hg help hgignore for
details.
To use a plain path name without any pattern matching, start it with path:. These path
names must completely match starting at the current repository root, and when the path
points to a directory, it is matched recursively. To match all files in a directory
non-recursively (not including any files in subdirectories), rootfilesin: can be used,
specifying an absolute path (relative to the repository root).
To use an extended glob, start a name with glob:. Globs are rooted at the current direc-
tory; a glob such as *.c will only match files in the current directory ending with .c.
rootglob: can be used instead of glob: for a glob that is rooted at the root of the repos-
itory.
The supported glob syntax extensions are ** to match any string across path separators and
{a,b} to mean "a or b".
To use a Perl/Python regular expression, start a name with re:. Regexp pattern matching
is anchored at the root of the repository.
To read name patterns from a file, use listfile: or listfile0:. The latter expects null
delimited patterns while the former expects line feeds. Each string read from the file is
itself treated as a file pattern.
To read a set of patterns from a file, use include: or subinclude:. include: will use all
the patterns from the given file and treat them as if they had been passed in manually.
subinclude: will only apply the patterns against files that are under the subinclude
file's directory. See hg help hgignore for details on the format of these files.
All patterns, except for glob: specified in command line (not for -I or -X options), can
match also against directories: files under matched directories are treated as matched.
For -I and -X options, glob: will match directories recursively.
Plain examples:
path:foo/bar a name bar in a directory named foo in the root
of the repository
path:path:name a file or directory named "path:name"
rootfilesin:foo/bar the files in a directory called foo/bar, but not any files
in its subdirectories and not a file bar in directory foo
Glob examples:
glob:*.c any name ending in ".c" in the current directory
*.c any name ending in ".c" in the current directory
**.c any name ending in ".c" in any subdirectory of the
current directory including itself.
foo/* any file in directory foo
foo/** any file in directory foo plus all its subdirectories,
recursively
foo/*.c any name ending in ".c" in the directory foo
foo/**.c any name ending in ".c" in any subdirectory of foo
including itself.
rootglob:*.c any name ending in ".c" in the root of the repository
Regexp examples:
re:.*\.c$ any name ending in ".c", anywhere in the repository
File examples:
listfile:list.txt read list from list.txt with one file pattern per line
listfile0:list.txt read list from list.txt with null byte delimiters
See also hg help filesets.
Include examples:
include:path/to/mypatternfile reads patterns to be applied to all paths
subinclude:path/to/subignorefile reads patterns specifically for paths in the
subdirectory
WORKING WITH PHASES
What are phases?
Phases are a system for tracking which changesets have been or should be shared. This
helps prevent common mistakes when modifying history (for instance, with the mq or rebase
extensions).
Each changeset in a repository is in one of the following phases:
o public : changeset is visible on a public server
o draft : changeset is not yet published
o secret : changeset should not be pushed, pulled, or cloned
These phases are ordered (public < draft < secret) and no changeset can be in a lower
phase than its ancestors. For instance, if a changeset is public, all its ancestors are
also public. Lastly, changeset phases should only be changed towards the public phase.
How are phases managed?
For the most part, phases should work transparently. By default, a changeset is created in
the draft phase and is moved into the public phase when it is pushed to another reposi-
tory.
Once changesets become public, extensions like mq and rebase will refuse to operate on
them to prevent creating duplicate changesets. Phases can also be manually manipulated
with the hg phase command if needed. See hg help -v phase for examples.
To make your commits secret by default, put this in your configuration file:
[phases]
new-commit = secret
Phases and servers
Normally, all servers are publishing by default. This means:
- all draft changesets that are pulled or cloned appear in phase
public on the client
- all draft changesets that are pushed appear as public on both
client and server
- secret changesets are neither pushed, pulled, or cloned
Note Pulling a draft changeset from a publishing server does not mark it as public on
the server side due to the read-only nature of pull.
Sometimes it may be desirable to push and pull changesets in the draft phase to share un-
finished work. This can be done by setting a repository to disable publishing in its con-
figuration file:
[phases]
publish = False
See hg help config for more information on configuration files.
Note Servers running older versions of Mercurial are treated as publishing.
Note Changesets in secret phase are not exchanged with the server. This applies to their
content: file names, file contents, and changeset metadata. For technical reasons,
the identifier (e.g. d825e4025e39) of the secret changeset may be communicated to
the server.
Examples
o list changesets in draft or secret phase:
hg log -r "not public()"
o change all secret changesets to draft:
hg phase --draft "secret()"
o forcibly move the current changeset and descendants from public to draft:
hg phase --force --draft .
o show a list of changeset revisions and each corresponding phase:
hg log --template "{rev} {phase}\n"
o resynchronize draft changesets relative to a remote repository:
hg phase -fd "outgoing(URL)"
See hg help phase for more information on manually manipulating phases.
SPECIFYING REVISIONS
Mercurial supports several ways to specify revisions.
Specifying single revisions
A plain integer is treated as a revision number. Negative integers are treated as sequen-
tial offsets from the tip, with -1 denoting the tip, -2 denoting the revision prior to the
tip, and so forth.
A 40-digit hexadecimal string is treated as a unique revision identifier. A hexadecimal
string less than 40 characters long is treated as a unique revision identifier and is re-
ferred to as a short-form identifier. A short-form identifier is only valid if it is the
prefix of exactly one full-length identifier.
Any other string is treated as a bookmark, tag, or branch name. A bookmark is a movable
pointer to a revision. A tag is a permanent name associated with a revision. A branch name
denotes the tipmost open branch head of that branch - or if they are all closed, the tip-
most closed head of the branch. Bookmark, tag, and branch names must not contain the ":"
character.
The reserved name "tip" always identifies the most recent revision.
The reserved name "null" indicates the null revision. This is the revision of an empty
repository, and the parent of revision 0.
The reserved name "." indicates the working directory parent. If no working directory is
checked out, it is equivalent to null. If an uncommitted merge is in progress, "." is the
revision of the first parent.
Finally, commands that expect a single revision (like hg update) also accept revsets (see
below for details). When given a revset, they use the last revision of the revset. A few
commands accept two single revisions (like hg diff). When given a revset, they use the
first and the last revisions of the revset.
Specifying multiple revisions
Mercurial supports a functional language for selecting a set of revisions. Expressions in
this language are called revsets.
The language supports a number of predicates which are joined by infix operators. Paren-
thesis can be used for grouping.
Identifiers such as branch names may need quoting with single or double quotes if they
contain characters like - or if they match one of the predefined predicates.
Special characters can be used in quoted identifiers by escaping them, e.g., \n is inter-
preted as a newline. To prevent them from being interpreted, strings can be prefixed with
r, e.g. r'...'.
Operators
There is a single prefix operator:
not x
Changesets not in x. Short form is ! x.
These are the supported infix operators:
x::y
A DAG range, meaning all changesets that are descendants of x and ancestors of y,
including x and y themselves. If the first endpoint is left out, this is equivalent
to ancestors(y), if the second is left out it is equivalent to descendants(x).
An alternative syntax is x..y.
x:y
All changesets with revision numbers between x and y, both inclusive. Either end-
point can be left out, they default to 0 and tip.
x and y
The intersection of changesets in x and y. Short form is x & y.
x or y
The union of changesets in x and y. There are two alternative short forms: x | y
and x + y.
x - y
Changesets in x but not in y.
x % y
Changesets that are ancestors of x but not ancestors of y (i.e. ::x - ::y). This
is shorthand notation for only(x, y) (see below). The second argument is optional
and, if left out, is equivalent to only(x).
x^n
The nth parent of x, n == 0, 1, or 2. For n == 0, x; for n == 1, the first parent
of each changeset in x; for n == 2, the second parent of changeset in x.
x~n
The nth first ancestor of x; x~0 is x; x~3 is x^^^. For n < 0, the nth unambiguous
descendent of x.
x ## y
Concatenate strings and identifiers into one string.
All other prefix, infix and postfix operators have lower priority than ##. For ex-
ample, a1 ## a2~2 is equivalent to (a1 ## a2)~2.
For example:
[revsetalias]
issue(a1) = grep(r'\bissue[ :]?' ## a1 ## r'\b|\bbug\(' ## a1 ## r'\)')
issue(1234) is equivalent to grep(r'\bissue[ :]?1234\b|\bbug\(1234\)') in this
case. This matches against all of "issue 1234", "issue:1234", "issue1234" and
"bug(1234)".
There is a single postfix operator:
x^
Equivalent to x^1, the first parent of each changeset in x.
Patterns
Where noted, predicates that perform string matching can accept a pattern string. The pat-
tern may be either a literal, or a regular expression. If the pattern starts with re:, the
remainder of the pattern is treated as a regular expression. Otherwise, it is treated as a
literal. To match a pattern that actually starts with re:, use the prefix literal:.
Matching is case-sensitive, unless otherwise noted. To perform a case- insensitive match
on a case-sensitive predicate, use a regular expression, prefixed with (?i).
For example, tag(r're:(?i)release') matches "release" or "RELEASE" or "Release", etc.
Predicates
The following predicates are supported:
adds(pattern)
Changesets that add a file matching pattern.
The pattern without explicit kind like glob: is expected to be relative to the cur-
rent directory and match against a file or a directory.
all()
All changesets, the same as 0:tip.
ancestor(*changeset)
A greatest common ancestor of the changesets.
Accepts 0 or more changesets. Will return empty list when passed no args. Great-
est common ancestor of a single changeset is that changeset.
ancestors(set[, depth])
Changesets that are ancestors of changesets in set, including the given changesets
themselves.
If depth is specified, the result only includes changesets up to the specified gen-
eration.
author(string)
Alias for user(string).
bisect(string)
Changesets marked in the specified bisect status:
o good, bad, skip: csets explicitly marked as good/bad/skip
o goods, bads : csets topologically good/bad
o range : csets taking part in the bisection
o pruned : csets that are goods, bads or skipped
o untested : csets whose fate is yet unknown
o ignored : csets ignored due to DAG topology
o current : the cset currently being bisected
bookmark([name])
The named bookmark or all bookmarks.
Pattern matching is supported for name. See hg help revisions.patterns.
branch(string or set)
All changesets belonging to the given branch or the branches of the given change-
sets.
Pattern matching is supported for string. See hg help revisions.patterns.
branchpoint()
Changesets with more than one child.
bundle()
Changesets in the bundle.
Bundle must be specified by the -R option.
children(set)
Child changesets of changesets in set.
closed()
Changeset is closed.
commonancestors(set)
Changesets that are ancestors of every changeset in set.
conflictlocal()
The local side of the merge, if currently in an unresolved merge.
"merge" here includes merge conflicts from e.g. 'hg rebase' or 'hg graft'.
conflictother()
The other side of the merge, if currently in an unresolved merge.
"merge" here includes merge conflicts from e.g. 'hg rebase' or 'hg graft'.
contains(pattern)
The revision's manifest contains a file matching pattern (but might not modify it).
See hg help patterns for information about file patterns.
The pattern without explicit kind like glob: is expected to be relative to the cur-
rent directory and match against a file exactly for efficiency.
converted([id])
Changesets converted from the given identifier in the old repository if present, or
all converted changesets if no identifier is specified.
date(interval)
Changesets within the interval, see hg help dates.
desc(string)
Search commit message for string. The match is case-insensitive.
Pattern matching is supported for string. See hg help revisions.patterns.
descendants(set[, depth])
Changesets which are descendants of changesets in set, including the given change-
sets themselves.
If depth is specified, the result only includes changesets up to the specified gen-
eration.
destination([set])
Changesets that were created by a graft, transplant or rebase operation, with the
given revisions specified as the source. Omitting the optional set is the same as
passing all().
diffcontains(pattern)
Search revision differences for when the pattern was added or removed.
The pattern may be a substring literal or a regular expression. See hg help revi-
sions.patterns.
draft()
Changeset in draft phase.
expectsize(set[, size])
Return the given revset if size matches the revset size. Abort if the revset
doesn't expect given size. size can either be an integer range or an integer.
For example, expectsize(0:1, 3:5) will abort as revset size is 2 and 2 is not be-
tween 3 and 5 inclusive.
extra(label, [value])
Changesets with the given label in the extra metadata, with the given optional
value.
Pattern matching is supported for value. See hg help revisions.patterns.
file(pattern)
Changesets affecting files matched by pattern.
For a faster but less accurate result, consider using filelog() instead.
This predicate uses glob: as the default kind of pattern.
filelog(pattern)
Changesets connected to the specified filelog.
For performance reasons, visits only revisions mentioned in the file-level filelog,
rather than filtering through all changesets (much faster, but doesn't include
deletes or duplicate changes). For a slower, more accurate result, use file().
The pattern without explicit kind like glob: is expected to be relative to the cur-
rent directory and match against a file exactly for efficiency.
first(set, [n])
An alias for limit().
follow([file[, startrev]])
An alias for ::. (ancestors of the working directory's first parent). If file pat-
tern is specified, the histories of files matching given pattern in the revision
given by startrev are followed, including copies.
followlines(file, fromline:toline[, startrev=., descend=False])
Changesets modifying file in line range ('fromline', 'toline').
Line range corresponds to 'file' content at 'startrev' and should hence be consis-
tent with file size. If startrev is not specified, working directory's parent is
used.
By default, ancestors of 'startrev' are returned. If 'descend' is True, descendants
of 'startrev' are returned though renames are (currently) not followed in this di-
rection.
grep(regex)
Like keyword(string) but accepts a regex. Use grep(r'...') to ensure special escape
characters are handled correctly. Unlike keyword(string), the match is case-sensi-
tive.
head()
Changeset is a named branch head.
heads(set)
Members of set with no children in set.
hidden()
Hidden changesets.
id(string)
Revision non-ambiguously specified by the given hex string prefix.
keyword(string)
Search commit message, user name, and names of changed files for string. The match
is case-insensitive.
For a regular expression or case sensitive search of these fields, use grep(regex).
last(set, [n])
Last n members of set, defaulting to 1.
limit(set[, n[, offset]])
First n members of set, defaulting to 1, starting from offset.
matching(revision [, field])
Changesets in which a given set of fields match the set of fields in the selected
revision or set.
To match more than one field pass the list of fields to match separated by spaces
(e.g. author description).
Valid fields are most regular revision fields and some special fields.
Regular revision fields are description, author, branch, date, files, phase, par-
ents, substate, user and diff. Note that author and user are synonyms. diff refers
to the contents of the revision. Two revisions matching their diff will also match
their files.
Special fields are summary and metadata: summary matches the first line of the de-
scription. metadata is equivalent to matching description user date (i.e. it
matches the main metadata fields).
metadata is the default field which is used when no fields are specified. You can
match more than one field at a time.
max(set)
Changeset with highest revision number in set.
merge()
Changeset is a merge changeset.
min(set)
Changeset with lowest revision number in set.
modifies(pattern)
Changesets modifying files matched by pattern.
The pattern without explicit kind like glob: is expected to be relative to the cur-
rent directory and match against a file or a directory.
named(namespace)
The changesets in a given namespace.
Pattern matching is supported for namespace. See hg help revisions.patterns.
nodefromfile(path)
An alias for ::. (ancestors of the working directory's first parent). If file pat-
tern is specified, the histories of files matching given pattern in the revision
given by startrev are followed, including copies.
none()
No changesets.
only(set, [set])
Changesets that are ancestors of the first set that are not ancestors of any other
head in the repo. If a second set is specified, the result is ancestors of the
first set that are not ancestors of the second set (i.e. ::<set1> - ::<set2>).
origin([set])
Changesets that were specified as a source for the grafts, transplants or rebases
that created the given revisions. Omitting the optional set is the same as passing
all(). If a changeset created by these operations is itself specified as a source
for one of these operations, only the source changeset for the first operation is
selected.
outgoing([path])
Changesets not found in the specified destination repository, or the default push
location.
If the location resolve to multiple repositories, the union of all outgoing change-
set will be used.
p1([set])
First parent of changesets in set, or the working directory.
p2([set])
Second parent of changesets in set, or the working directory.
parents([set])
The set of all parents for all changesets in set, or the working directory.
present(set)
An empty set, if any revision in set isn't found; otherwise, all revisions in set.
If any of specified revisions is not present in the local repository, the query is
normally aborted. But this predicate allows the query to continue even in such
cases.
public()
Changeset in public phase.
remote([id [,path]])
Local revision that corresponds to the given identifier in a remote repository, if
present. Here, the '.' identifier is a synonym for the current local branch.
removes(pattern)
Changesets which remove files matching pattern.
The pattern without explicit kind like glob: is expected to be relative to the cur-
rent directory and match against a file or a directory.
rev(number)
Revision with the given numeric identifier.
reverse(set)
Reverse order of set.
revset(set)
Strictly interpret the content as a revset.
The content of this special predicate will be strictly interpreted as a revset. For
example, revset(id(0)) will be interpreted as "id(0)" without possible ambiguity
with a "id(0)" bookmark or tag.
roots(set)
Changesets in set with no parent changeset in set.
secret()
Changeset in secret phase.
sort(set[, [-]key... [, ...]])
Sort set by keys. The default sort order is ascending, specify a key as -key to
sort in descending order.
The keys can be:
o rev for the revision number,
o branch for the branch name,
o desc for the commit message (description),
o user for user name (author can be used as an alias),
o date for the commit date
o topo for a reverse topographical sort
o node the nodeid of the revision
The topo sort order cannot be combined with other sort keys. This sort takes one
optional argument, topo.firstbranch, which takes a revset that specifies what topo-
graphical branches to prioritize in the sort.
subrepo([pattern])
Changesets that add, modify or remove the given subrepo. If no subrepo pattern is
named, any subrepo changes are returned.
tag([name])
The specified tag by name, or all tagged revisions if no name is given.
Pattern matching is supported for name. See hg help revisions.patterns.
user(string)
User name contains string. The match is case-insensitive.
Pattern matching is supported for string. See hg help revisions.patterns.
Aliases
New predicates (known as "aliases") can be defined, using any combination of existing
predicates or other aliases. An alias definition looks like:
<alias> = <definition>
in the revsetalias section of a Mercurial configuration file. Arguments of the form a1,
a2, etc. are substituted from the alias into the definition.
For example,
[revsetalias]
h = heads()
d(s) = sort(s, date)
rs(s, k) = reverse(sort(s, k))
defines three aliases, h, d, and rs. rs(0:tip, author) is exactly equivalent to re-
verse(sort(0:tip, author)).
Equivalents
Command line equivalents for hg log:
-f -> ::.
-d x -> date(x)
-k x -> keyword(x)
-m -> merge()
-u x -> user(x)
-b x -> branch(x)
-P x -> !::x
-l x -> limit(expr, x)
Examples
Some sample queries:
o Changesets on the default branch:
hg log -r "branch(default)"
o Changesets on the default branch since tag 1.5 (excluding merges):
hg log -r "branch(default) and 1.5:: and not merge()"
o Open branch heads:
hg log -r "head() and not closed()"
o Changesets between tags 1.3 and 1.5 mentioning "bug" that affect hgext/*:
hg log -r "1.3::1.5 and keyword(bug) and file('hgext/*')"
o Changesets committed in May 2008, sorted by user:
hg log -r "sort(date('May 2008'), user)"
o Changesets mentioning "bug" or "issue" that are not in a tagged release:
hg log -r "(keyword(bug) or keyword(issue)) and not ancestors(tag())"
o Update to the commit that bookmark @ is pointing to, without activating the bookmark
(this works because the last revision of the revset is used):
hg update :@
o Show diff between tags 1.3 and 1.5 (this works because the first and the last revisions
of the revset are used):
hg diff -r 1.3::1.5
RUST IN MERCURIAL
Mercurial can be augmented with Rust extensions for speeding up certain operations.
Compatibility
Though the Rust extensions are only tested by the project under Linux, users of MacOS,
FreeBSD and other UNIX-likes have been using the Rust extensions. Your mileage may vary,
but by all means do give us feedback or signal your interest for better support.
No Rust extensions are available for Windows at this time.
Features
The following operations are sped up when using Rust:
o discovery of differences between repositories (pull/push)
o nodemap (see hg help config.format.use-persistent-nodemap)
o all commands using the dirstate (status, commit, diff, add, update, etc.)
o dirstate-v2 (see hg help config.format.use-dirstate-v2)
o iteration over ancestors in a graph
More features are in the works, and improvements on the above listed are still in
progress. For more experimental work see the "rhg" section.
Checking for Rust
You may already have the Rust extensions depending on how you install Mercurial.
$ hg debuginstall | grep -i rust checking Rust extensions (installed) checking module
policy (rust+c-allow)
If those lines don't even exist, you're using an old version of hg which does not have any
Rust extensions yet.
Installing
You will need cargo to be in your $PATH. See the "MSRV" section for which version to use.
Using pip
Users of pip can install the Rust extensions with the following command:
$ pip install mercurial --global-option --rust --no-use-pep517
--no-use-pep517 is here to tell pip to preserve backwards compatibility with the legacy
setup.py system. Mercurial has not yet migrated its complex setup to the new system, so we
still need this to add compiled extensions.
This might take a couple of minutes because you're compiling everything.
See the "Checking for Rust" section to see if the install succeeded.
From your distribution
Some distributions are shipping Mercurial with Rust extensions enabled and pre-compiled
(meaning you won't have to install cargo), or allow you to specify an install flag. Check
with your specific distribution for how to do that, or ask their team to add support for
hg+Rust!
From source
Please refer to the rust/README.rst file in the Mercurial repository for instructions on
how to install from source.
MSRV
The minimum supported Rust version is currently 1.48.0. The project's policy is to follow
the version from Debian stable, to make the distributions' job easier.
rhg
There exists an experimental pure-Rust version of Mercurial called rhg with a fallback
mechanism for unsupported invocations. It allows for much faster execution of certain com-
mands while adding no discernable overhead for the rest.
The only way of trying it out is by building it from source. Please refer to
rust/README.rst in the Mercurial repository.
Contributing
If you would like to help the Rust endeavor, please refer to rust/README.rst in the Mercu-
rial repository.
USING MERCURIAL FROM SCRIPTS AND AUTOMATION
It is common for machines (as opposed to humans) to consume Mercurial. This help topic
describes some of the considerations for interfacing machines with Mercurial.
Choosing an Interface
Machines have a choice of several methods to interface with Mercurial. These include:
o Executing the hg process
o Querying a HTTP server
o Calling out to a command server
Executing hg processes is very similar to how humans interact with Mercurial in the shell.
It should already be familiar to you.
hg serve can be used to start a server. By default, this will start a "hgweb" HTTP server.
This HTTP server has support for machine-readable output, such as JSON. For more, see hg
help hgweb.
hg serve can also start a "command server." Clients can connect to this server and issue
Mercurial commands over a special protocol. For more details on the command server, in-
cluding links to client libraries, see https://www.mercurial-scm.org/wiki/CommandServer.
hg serve based interfaces (the hgweb and command servers) have the advantage over simple
hg process invocations in that they are likely more efficient. This is because there is
significant overhead to spawn new Python processes.
Tip If you need to invoke several hg processes in short order and/or performance is im-
portant to you, use of a server-based interface is highly recommended.
Environment Variables
As documented in hg help environment, various environment variables influence the opera-
tion of Mercurial. The following are particularly relevant for machines consuming Mercu-
rial:
HGPLAIN
If not set, Mercurial's output could be influenced by configuration settings that
impact its encoding, verbose mode, localization, etc.
It is highly recommended for machines to set this variable when invoking hg pro-
cesses.
HGENCODING
If not set, the locale used by Mercurial will be detected from the environment. If
the determined locale does not support display of certain characters, Mercurial may
render these character sequences incorrectly (often by using "?" as a placeholder
for invalid characters in the current locale).
Explicitly setting this environment variable is a good practice to guarantee con-
sistent results. "utf-8" is a good choice on UNIX-like environments.
HGRCPATH
If not set, Mercurial will inherit config options from config files using the
process described in hg help config. This includes inheriting user or system-wide
config files.
When utmost control over the Mercurial configuration is desired, the value of HGRC-
PATH can be set to an explicit file with known good configs. In rare cases, the
value can be set to an empty file or the null device (often /dev/null) to bypass
loading of any user or system config files. Note that these approaches can have un-
intended consequences, as the user and system config files often define things like
the username and extensions that may be required to interface with a repository.
HGRCSKIPREPO
When set, the .hg/hgrc from repositories are not read.
Note that not reading the repository's configuration can have unintended conse-
quences, as the repository config files can define things like extensions that are
required for access to the repository.
Command-line Flags
Mercurial's default command-line parser is designed for humans, and is not robust against
malicious input. For instance, you can start a debugger by passing --debugger as an option
value:
$ REV=--debugger sh -c 'hg log -r "$REV"'
This happens because several command-line flags need to be scanned without using a con-
crete command table, which may be modified while loading repository settings and exten-
sions.
Since Mercurial 4.4.2, the parsing of such flags may be restricted by setting HG-
PLAIN=+strictflags. When this feature is enabled, all early options (e.g. -R/--repository,
--cwd, --config) must be specified first amongst the other global options, and cannot be
injected to an arbitrary location:
$ HGPLAIN=+strictflags hg -R "$REPO" log -r "$REV"
In earlier Mercurial versions where +strictflags isn't available, you can mitigate the is-
sue by concatenating an option value with its flag:
$ hg log -r"$REV" --keyword="$KEYWORD"
Consuming Command Output
It is common for machines to need to parse the output of Mercurial commands for relevant
data. This section describes the various techniques for doing so.
Parsing Raw Command Output
Likely the simplest and most effective solution for consuming command output is to simply
invoke hg commands as you would as a user and parse their output.
The output of many commands can easily be parsed with tools like grep, sed, and awk.
A potential downside with parsing command output is that the output of commands can change
when Mercurial is upgraded. While Mercurial does generally strive for strong backwards
compatibility, command output does occasionally change. Having tests for your automated
interactions with hg commands is generally recommended, but is even more important when
raw command output parsing is involved.
Using Templates to Control Output
Many hg commands support templatized output via the -T/--template argument. For more, see
hg help templates.
Templates are useful for explicitly controlling output so that you get exactly the data
you want formatted how you want it. For example, log -T {node}\n can be used to print a
newline delimited list of changeset nodes instead of a human-tailored output containing
authors, dates, descriptions, etc.
Tip If parsing raw command output is too complicated, consider using templates to make
your life easier.
The -T/--template argument allows specifying pre-defined styles. Mercurial ships with the
machine-readable styles cbor, json, and xml, which provide CBOR, JSON, and XML output, re-
spectively. These are useful for producing output that is machine readable as-is.
(Mercurial 5.0 is required for CBOR style.)
Important
The json and xml styles are considered experimental. While they may be attractive
to use for easily obtaining machine-readable output, their behavior may change in
subsequent versions.
These styles may also exhibit unexpected results when dealing with certain encod-
ings. Mercurial treats things like filenames as a series of bytes and normalizing
certain byte sequences to JSON or XML with certain encoding settings can lead to
surprises.
Command Server Output
If using the command server to interact with Mercurial, you are likely using an existing
library/API that abstracts implementation details of the command server. If so, this in-
terface layer may perform parsing for you, saving you the work of implementing it your-
self.
Output Verbosity
Commands often have varying output verbosity, even when machine readable styles are being
used (e.g. -T json). Adding -v/--verbose and --debug to the command's arguments can in-
crease the amount of data exposed by Mercurial.
An alternate way to get the data you need is by explicitly specifying a template.
Other Topics
revsets
Revisions sets is a functional query language for selecting a set of revisions.
Think of it as SQL for Mercurial repositories. Revsets are useful for querying
repositories for specific data.
See hg help revsets for more.
share extension
The share extension provides functionality for sharing repository data across sev-
eral working copies. It can even automatically "pool" storage for logically related
repositories when cloning.
Configuring the share extension can lead to significant resource utilization reduc-
tion, particularly around disk space and the network. This is especially true for
continuous integration (CI) environments.
See hg help -e share for more.
SUBREPOSITORIES
Subrepositories let you nest external repositories or projects into a parent Mercurial
repository, and make commands operate on them as a group.
Mercurial currently supports Mercurial, Git, and Subversion subrepositories.
Subrepositories are made of three components:
1. Nested repository checkouts. They can appear anywhere in the parent working directory.
2. Nested repository references. They are defined in .hgsub, which should be placed in the
root of working directory, and tell where the subrepository checkouts come from. Mercu-
rial subrepositories are referenced like:
path/to/nested = https://example.com/nested/repo/path
Git and Subversion subrepos are also supported:
path/to/nested = [git]git://example.com/nested/repo/path
path/to/nested = [svn]https://example.com/nested/trunk/path
where path/to/nested is the checkout location relatively to the parent Mercurial root,
and https://example.com/nested/repo/path is the source repository path. The source can
also reference a filesystem path.
Note that .hgsub does not exist by default in Mercurial repositories, you have to cre-
ate and add it to the parent repository before using subrepositories.
3. Nested repository states. They are defined in .hgsubstate, which is placed in the root
of working directory, and capture whatever information is required to restore the sub-
repositories to the state they were committed in a parent repository changeset. Mercu-
rial automatically record the nested repositories states when committing in the parent
repository.
Note
The .hgsubstate file should not be edited manually.
Adding a Subrepository
If .hgsub does not exist, create it and add it to the parent repository. Clone or checkout
the external projects where you want it to live in the parent repository. Edit .hgsub and
add the subrepository entry as described above. At this point, the subrepository is
tracked and the next commit will record its state in .hgsubstate and bind it to the com-
mitted changeset.
Synchronizing a Subrepository
Subrepos do not automatically track the latest changeset of their sources. Instead, they
are updated to the changeset that corresponds with the changeset checked out in the
top-level changeset. This is so developers always get a consistent set of compatible code
and libraries when they update.
Thus, updating subrepos is a manual process. Simply check out target subrepo at the de-
sired revision, test in the top-level repo, then commit in the parent repository to record
the new combination.
Deleting a Subrepository
To remove a subrepository from the parent repository, delete its reference from .hgsub,
then remove its files.
Interaction with Mercurial Commands
add add does not recurse in subrepos unless -S/--subrepos is specified. However, if
you specify the full path of a file in a subrepo, it will be added even without
-S/--subrepos specified. Subversion subrepositories are currently silently ig-
nored.
addremove
addremove does not recurse into subrepos unless -S/--subrepos is specified. How-
ever, if you specify the full path of a directory in a subrepo, addremove will be
performed on it even without -S/--subrepos being specified. Git and Subversion
subrepositories will print a warning and continue.
archive
archive does not recurse in subrepositories unless -S/--subrepos is specified.
cat Git subrepositories only support exact file matches. Subversion subrepositories
are currently ignored.
commit commit creates a consistent snapshot of the state of the entire project and its
subrepositories. If any subrepositories have been modified, Mercurial will abort.
Mercurial can be made to instead commit all modified subrepositories by specifying
-S/--subrepos, or setting "ui.commitsubrepos=True" in a configuration file (see hg
help config). After there are no longer any modified subrepositories, it records
their state and finally commits it in the parent repository. The --addremove op-
tion also honors the -S/--subrepos option. However, Git and Subversion subreposi-
tories will print a warning and abort.
diff diff does not recurse in subrepos unless -S/--subrepos is specified. However, if
you specify the full path of a file or directory in a subrepo, it will be diffed
even without -S/--subrepos being specified. Subversion subrepositories are cur-
rently silently ignored.
files files does not recurse into subrepos unless -S/--subrepos is specified. However,
if you specify the full path of a file or directory in a subrepo, it will be dis-
played even without -S/--subrepos being specified. Git and Subversion subreposito-
ries are currently silently ignored.
forget forget currently only handles exact file matches in subrepos. Git and Subversion
subrepositories are currently silently ignored.
incoming
incoming does not recurse in subrepos unless -S/--subrepos is specified. Git and
Subversion subrepositories are currently silently ignored.
outgoing
outgoing does not recurse in subrepos unless -S/--subrepos is specified. Git and
Subversion subrepositories are currently silently ignored.
pull pull is not recursive since it is not clear what to pull prior to running hg update
. Listing and retrieving all subrepositories changes referenced by the parent
repository pulled changesets is expensive at best, impossible in the Subversion
case.
push Mercurial will automatically push all subrepositories first when the parent reposi-
tory is being pushed. This ensures new subrepository changes are available when
referenced by top-level repositories. Push is a no-op for Subversion subreposito-
ries.
serve serve does not recurse into subrepositories unless -S/--subrepos is specified. Git
and Subversion subrepositories are currently silently ignored.
status status does not recurse into subrepositories unless -S/--subrepos is specified.
Subrepository changes are displayed as regular Mercurial changes on the subreposi-
tory elements. Subversion subrepositories are currently silently ignored.
remove remove does not recurse into subrepositories unless -S/--subrepos is specified.
However, if you specify a file or directory path in a subrepo, it will be removed
even without -S/--subrepos. Git and Subversion subrepositories are currently
silently ignored.
update update restores the subrepos in the state they were originally committed in target
changeset. If the recorded changeset is not available in the current subrepository,
Mercurial will pull it in first before updating. This means that updating can re-
quire network access when using subrepositories.
Remapping Subrepositories Sources
A subrepository source location may change during a project life, invalidating references
stored in the parent repository history. To fix this, rewriting rules can be defined in
parent repository hgrc file or in Mercurial configuration. See the [subpaths] section in
hgrc(5) for more details.
TEMPLATE USAGE
Mercurial allows you to customize output of commands through templates. You can either
pass in a template or select an existing template-style from the command line, via the
--template option.
You can customize output for any "log-like" command: log, outgoing, incoming, tip, par-
ents, and heads.
Some built-in styles are packaged with Mercurial. These can be listed with hg log --tem-
plate list. Example usage:
$ hg log -r1.0::1.1 --template changelog
A template is a piece of text, with markup to invoke variable expansion:
$ hg log -r1 --template "{node}\n"
b56ce7b07c52de7d5fd79fb89701ea538af65746
Keywords
Strings in curly braces are called keywords. The availability of keywords depends on the
exact context of the templater. These keywords are usually available for templating a
log-like command:
_fast_rank
the rank of a changeset if cached
The rank of a revision is the size of the sub-graph it defines as a head. Equiva-
lently, the rank of a revision r is the size of the set ancestors(r), r included.
activebookmark
String. The active bookmark, if it is associated with the changeset.
author Alias for {user}
bisect String. The changeset bisection status.
bookmarks
List of strings. Any bookmarks associated with the changeset. Also sets 'active',
the name of the active bookmark.
branch String. The name of the branch on which the changeset was committed.
changessincelatesttag
Integer. All ancestors not in the latest tag.
children
List of strings. The children of the changeset.
date Date information. The date when the changeset was committed.
desc String. The text of the changeset description.
diffstat
String. Statistics of changes with the following format: "modified files:
+added/-removed lines"
extras List of dicts with key, value entries of the 'extras' field of this changeset.
file_adds
List of strings. Files added by this changeset.
file_copies
List of strings. Files copied in this changeset with their sources.
file_copies_switch
List of strings. Like "file_copies" but displayed only if the --copied switch is
set.
file_dels
List of strings. Files removed by this changeset.
file_mods
List of strings. Files modified by this changeset.
files List of strings. All files modified, added, or removed by this changeset.
graphnode
String. The character representing the changeset node in an ASCII revision graph.
graphwidth
Integer. The width of the graph drawn by 'log --graph' or zero.
index Integer. The current iteration of the loop. (0 indexed)
latesttag
List of strings. The global tags on the most recent globally tagged ancestor of
this changeset. If no such tags exist, the list consists of the single string
"null".
latesttagdistance
Integer. Longest path to the latest tag.
namespaces
Dict of lists. Names attached to this changeset per namespace.
negrev Integer. The repository-local changeset negative revision number, which counts in
the opposite direction.
node String. The changeset identification hash, as a 40 hexadecimal digit string.
onelinesummary
String. A one-line summary for the ctx (not including trailing newline). The de-
fault template be overridden in command-templates.oneline-summary.
p1 Changeset. The changeset's first parent. {p1.rev} for the revision number, and
{p1.node} for the identification hash.
p2 Changeset. The changeset's second parent. {p2.rev} for the revision number, and
{p2.node} for the identification hash.
parents
List of strings. The parents of the changeset in "rev:node" format. If the change-
set has only one "natural" parent (the predecessor revision) nothing is shown.
peerurls
A dictionary of repository locations defined in the [paths] section of your config-
uration file.
phase String. The changeset phase name.
reporoot
String. The root directory of the current repository.
rev Integer. The repository-local changeset revision number.
subrepos
List of strings. Updated subrepositories in the changeset.
tags List of strings. Any tags associated with the changeset.
termwidth
Integer. The width of the current terminal.
user String. The unmodified author of the changeset.
verbosity
String. The current output verbosity in 'debug', 'quiet', 'verbose', or ''.
The "date" keyword does not produce human-readable output. If you want to use a date in
your output, you can use a filter to process it. Filters are functions which return a
string based on the input variable. Be sure to use the stringify filter first when you're
applying a string-input filter to a list-like input variable. You can also use a chain of
filters to get the desired output:
$ hg tip --template "{date|isodate}\n"
2008-08-21 18:22 +0000
Filters
List of filters:
addbreaks
Any text. Add an XHTML "<br />" tag before the end of every line except the last.
age Date. Returns a human-readable date/time difference between the given date/time and
the current date/time.
basename
Any text. Treats the text as a path, and returns the last component of the path af-
ter splitting by the path separator. For example, "foo/bar/baz" becomes "baz" and
"foo/bar//" becomes "".
cbor Any object. Serializes the object to CBOR bytes.
commondir
List of text. Treats each list item as file name with / as path separator and re-
turns the longest common directory prefix shared by all list items. Returns the
empty string if no common prefix exists.
The list items are not normalized, i.e. "foo/../bar" is handled as file "bar" in
the directory "foo/..". Leading slashes are ignored.
For example, ["foo/bar/baz", "foo/baz/bar"] becomes "foo" and ["foo/bar", "baz"]
becomes "".
count List or text. Returns the length as an integer.
dirname
Any text. Treats the text as a path, and strips the last component of the path af-
ter splitting by the path separator.
domain Any text. Finds the first string that looks like an email address, and extracts
just the domain component. Example: User <user AT example.com> becomes example.com.
email Any text. Extracts the first string that looks like an email address. Example: User
<user AT example.com> becomes user AT example.com.
emailuser
Any text. Returns the user portion of an email address.
escape Any text. Replaces the special XML/XHTML characters "&", "<" and ">" with XML enti-
ties, and filters out NUL characters.
fill68 Any text. Wraps the text to fit in 68 columns.
fill76 Any text. Wraps the text to fit in 76 columns.
firstline
Any text. Returns the first line of text.
hex Any text. Convert a binary Mercurial node identifier into its long hexadecimal rep-
resentation.

lower Any text. Converts the text to lowercase.
nonempty
Any text. Returns '(none)' if the string is empty.
obfuscate
Any text. Returns the input text rendered as a sequence of XML entities.
person Any text. Returns the name before an email address, interpreting it as per RFC
5322.
revescape
Any text. Escapes all "special" characters, except @. Forward slashes are escaped
twice to prevent web servers from prematurely unescaping them. For example, "@foo
bar/baz" becomes "@foo%20bar%252Fbaz".

tabindent
Any text. Returns the text, with every non-empty line except the first starting
with a tab character.
upper Any text. Converts the text to uppercase.
urlescape

"foo%20bar".
user Any text. Returns a short representation of a user name or email address.
utf8 Any text. Converts from the local character encoding to UTF-8.
Note that a filter is nothing more than a function call, i.e. expr|filter is equivalent
to filter(expr).
Functions
In addition to filters, there are some basic built-in functions:
config(section, name[, default])
Returns the requested hgrc config option as a string.
configbool(section, name[, default])
Returns the requested hgrc config option as a boolean.
configint(section, name[, default])
Returns the requested hgrc config option as an integer.
date(date[, fmt])
Format a date. See hg help dates for formatting strings. The default is a Unix date
format, including the timezone: "Mon Sep 04 15:13:13 2006 0700".
dict([[key=]value...])
Construct a dict from key-value pairs. A key may be omitted if a value expression
can provide an unambiguous name.
diff([includepattern [, excludepattern]])
Show a diff, optionally specifying files to include or exclude.
files(pattern)
All files of the current changeset matching the pattern. See hg help patterns.
fill(text[, width[, initialident[, hangindent]]])
Fill many paragraphs with optional indentation. See the "fill" filter.
filter(iterable[, expr])
Remove empty elements from a list or a dict. If expr specified, it's applied to
each element to test emptiness.
get(dict, key)
Get an attribute/key from an object. Some keywords are complex types. This function
allows you to obtain the value of an attribute on these types.
if(expr, then[, else])
Conditionally execute based on the result of an expression.
ifcontains(needle, haystack, then[, else])
Conditionally execute based on whether the item "needle" is in "haystack".
ifeq(expr1, expr2, then[, else])
Conditionally execute based on whether 2 items are equivalent.
indent(text, indentchars[, firstline])
Indents all non-empty lines with the characters given in the indentchars string. An
optional third parameter will override the indent for the first line only if
present.
join(list, sep)
Join items in a list with a delimiter.
label(label, expr)
Apply a label to generated content. Content with a label applied can result in ad-
ditional post-processing, such as automatic colorization.
latesttag([pattern])
The global tags matching the given pattern on the most recent globally tagged an-
cestor of this changeset. If no such tags exist, the "{tag}" template resolves to
the string "null". See hg help revisions.patterns for the pattern syntax.
localdate(date[, tz])
Converts a date to the specified timezone. The default is local date.
mailmap(author)
Return the author, updated according to the value set in the .mailmap file
max(iterable)
Return the max of an iterable
min(iterable)
Return the min of an iterable
mod(a, b)
Calculate a mod b such that a / b + a mod b == a
pad(text, width[, fillchar=' '[, left=False[, truncate=False]]])
Pad text with a fill character.
relpath(path)
Convert a repository-absolute path into a filesystem path relative to the current
working directory.
revset(query[, formatargs...])
Execute a revision set query. See hg help revset.
rstdoc(text, style)
Format reStructuredText.
search(pattern, text)
Look for the first text matching the regular expression pattern. Groups are acces-
sible as {1}, {2}, ... in %-mapped template.
separate(sep, args...)
Add a separator between non-empty arguments.
shortest(node, minlength=4)
Obtain the shortest representation of a node.
startswith(pattern, text)
Returns the value from the "text" argument if it begins with the content from the
"pattern" argument.
strip(text[, chars])
Strip characters from a string. By default, strips all leading and trailing white-
space.
sub(pattern, replacement, expression)
Perform text substitution using regular expressions.
subsetparents(rev, revset)
Look up parents of the rev in the sub graph given by the revset.
word(number, text[, separator])
Return the nth word from a string.
Operators
We provide a limited set of infix arithmetic operations on integers:
+ for addition
- for subtraction
* for multiplication
/ for floor division (division rounded to integer nearest -infinity)
Division fulfills the law x = x / y + mod(x, y).
Also, for any expression that returns a list, there is a list operator:
expr % "{template}"
As seen in the above example, {template} is interpreted as a template. To prevent it from
being interpreted, you can use an escape character \{ or a raw string prefix, r'...'.
The dot operator can be used as a shorthand for accessing a sub item:
o expr.member is roughly equivalent to expr % '{member}' if expr returns a non-list/dict.
The returned value is not stringified.
o dict.key is identical to get(dict, 'key').
Aliases
New keywords and functions can be defined in the templatealias section of a Mercurial con-
figuration file:
<alias> = <definition>
Arguments of the form a1, a2, etc. are substituted from the alias into the definition.
For example,
[templatealias]
r = rev
rn = "{r}:{node|short}"
leftpad(s, w) = pad(s, w, ' ', True)
defines two symbol aliases, r and rn, and a function alias leftpad().
It's also possible to specify complete template strings, using the templates section. The
syntax used is the general template string syntax.
For example,
[templates]
nodedate = "{node|short}: {date(date, "%Y-%m-%d")}\n"
defines a template, nodedate, which can be called like:
$ hg log -r . -Tnodedate
A template defined in templates section can also be referenced from another template:
$ hg log -r . -T "{rev} {nodedate}"
but be aware that the keywords cannot be overridden by templates. For example, a template
defined as templates.rev cannot be referenced as {rev}.
A template defined in templates section may have sub templates which are inserted be-
fore/after/between items:
[templates]
myjson = ' {dict(rev, node|short)|json}'
myjson:docheader = '\{\n'
myjson:docfooter = '\n}\n'
myjson:separator = ',\n'
Examples
Some sample command line templates:
o Format lists, e.g. files:
$ hg log -r 0 --template "files:\n{files % ' {file}\n'}"
o Join the list of files with a ", ":
$ hg log -r 0 --template "files: {join(files, ', ')}\n"
o Join the list of files ending with ".py" with a ", ":
$ hg log -r 0 --template "pythonfiles: {join(files('**.py'), ', ')}\n"
o Separate non-empty arguments by a " ":
$ hg log -r 0 --template "{separate(' ', node, bookmarks, tags}\n"
o Modify each line of a commit description:
$ hg log --template "{splitlines(desc) % '**** {line}\n'}"
o Format date:
$ hg log -r 0 --template "{date(date, '%Y')}\n"
o Display date in UTC:
$ hg log -r 0 --template "{localdate(date, 'UTC')|date}\n"
o Output the description set to a fill-width of 30:
$ hg log -r 0 --template "{fill(desc, 30)}"
o Use a conditional to test for the default branch:
$ hg log -r 0 --template "{ifeq(branch, 'default', 'on the main branch',
'on branch {branch}')}\n"
o Append a newline if not empty:
$ hg tip --template "{if(author, '{author}\n')}"
o Label the output for use with the color extension:
$ hg log -r 0 --template "{label('changeset.{phase}', node|short)}\n"
o Invert the firstline filter, i.e. everything but the first line:
$ hg log -r 0 --template "{sub(r'^.*\n?\n?', '', desc)}\n"
o Display the contents of the 'extra' field, one per line:
$ hg log -r 0 --template "{join(extras, '\n')}\n"
o Mark the active bookmark with '*':
$ hg log --template "{bookmarks % '{bookmark}{ifeq(bookmark, active, '*')} '}\n"
o Find the previous release candidate tag, the distance and changes since the tag:
$ hg log -r . --template "{latesttag('re:^.*-rc$') % '{tag}, {changes}, {distance}'}\n"
o Mark the working copy parent with '@':
$ hg log --template "{ifcontains(rev, revset('.'), '@')}\n"
o Show details of parent revisions:
$ hg log --template "{revset('parents(%d)', rev) % '{desc|firstline}\n'}"
o Show only commit descriptions that start with "template":
$ hg log --template "{startswith('template', firstline(desc))}\n"
o Print the first word of each line of a commit message:
$ hg log --template "{word(0, desc)}\n"
URL PATHS
Valid URLs are of the form:
local/filesystem/path[#revision]
file://local/filesystem/path[#revision]
http://[user[:pass]@]host[:port]/[path][#revision]
https://[user[:pass]@]host[:port]/[path][#revision]
ssh://[user@]host[:port]/[path][#revision]
path://pathname
Paths in the local filesystem can either point to Mercurial repositories or to bundle
files (as created by hg bundle or hg incoming --bundle). See also hg help paths.
An optional identifier after # indicates a particular branch, tag, or changeset to use
from the remote repository. See also hg help revisions.
Some features, such as pushing to http:// and https:// URLs are only possible if the fea-
ture is explicitly enabled on the remote Mercurial server.
Note that the security of HTTPS URLs depends on proper configuration of web.cacerts.
Some notes about using SSH with Mercurial:
o SSH requires an accessible shell account on the destination machine and a copy of hg in
the remote path or specified with remotecmd.
o path is relative to the remote user's home directory by default. Use an extra slash at
the start of a path to specify an absolute path:
ssh://example.com//tmp/repository
o Mercurial doesn't use its own compression via SSH; the right thing to do is to configure
it in your ~/.ssh/config, e.g.:
Host *.mylocalnetwork.example.com
Compression no
Host *
Compression yes
Alternatively specify "ssh -C" as your ssh command in your configuration file or with
the --ssh command line option.
These URLs can all be stored in your configuration file with path aliases under the
[paths] section like so:
[paths]
alias1 = URL1
alias2 = URL2
...
You can then use the alias for any command that uses a URL (for example hg pull alias1
will be treated as hg pull URL1).
Two path aliases are special because they are used as defaults when you do not provide the
URL to a command:
default:
When you create a repository with hg clone, the clone command saves the location of
the source repository as the new repository's 'default' path. This is then used
when you omit path from push- and pull-like commands (including incoming and outgo-
ing).
default-push:
The push command will look for a path named 'default-push', and prefer it over 'de-
fault' if both are defined.
These alias can also be use in the path:// scheme:
[paths]
alias1 = URL1
alias2 = path://alias1
...
check hg help config.paths for details about the behavior of such "sub-path".
EXTENSIONS
This section contains help for extensions that are distributed together with Mercurial.
Help for other extensions is available in the help system.
absorb
apply working directory changes to changesets (EXPERIMENTAL)
The absorb extension provides a command to use annotate information to amend modified
chunks into the corresponding non-public changesets.
[absorb]
# only check 50 recent non-public changesets at most
max-stack-size = 50
# whether to add noise to new commits to avoid obsolescence cycle
add-noise = 1
# make `amend --correlated` a shortcut to the main command
amend-flag = correlated
[color]
absorb.description = yellow
absorb.node = blue bold
absorb.path = bold
Commands
Change creation
absorb
incorporate corrections into the stack of draft changesets:
hg absorb [OPTION] [FILE]...
absorb analyzes each change in your working directory and attempts to amend the changed
lines into the changesets in your stack that first introduced those lines.
If absorb cannot find an unambiguous changeset to amend for a change, that change will be
left in the working directory, untouched. They can be observed by hg status or hg diff
afterwards. In other words, absorb does not write to the working directory.
Changesets outside the revset ::. and not public() and not merge() will not be changed.
Changesets that become empty after applying the changes will be deleted.
By default, absorb will show what it plans to do and prompt for confirmation. If you are
confident that the changes will be absorbed to the correct place, run hg absorb -a to ap-
ply the changes immediately.
Returns 0 on success, 1 if all chunks were ignored and nothing amended.
Options:
-a, --apply-changes
apply changes without prompting for confirmation
-p, --print-changes
always print which changesets are modified by which changes
-i, --interactive
interactively select which chunks to apply
-e, --edit-lines
edit what lines belong to which changesets before commit (EXPERIMENTAL)
-n, --dry-run
do not perform actions, just print output
--style <STYLE>
display using template map file (DEPRECATED)
-T,--template <TEMPLATE>
display with template
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
acl
hooks for controlling repository access
This hook makes it possible to allow or deny write access to given branches and paths of a
repository when receiving incoming changesets via pretxnchangegroup and pretxncommit.
The authorization is matched based on the local user name on the system where the hook
runs, and not the committer of the original changeset (since the latter is merely informa-
tive).
The acl hook is best used along with a restricted shell like hgsh, preventing authenticat-
ing users from doing anything other than pushing or pulling. The hook is not safe to use
if users have interactive shell access, as they can then disable the hook. Nor is it safe
if remote users share an account, because then there is no way to distinguish them.
The order in which access checks are performed is:
1. Deny list for branches (section acl.deny.branches)
2. Allow list for branches (section acl.allow.branches)
3. Deny list for paths (section acl.deny)
4. Allow list for paths (section acl.allow)
The allow and deny sections take key-value pairs.
Branch-based Access Control
Use the acl.deny.branches and acl.allow.branches sections to have branch-based access con-
trol. Keys in these sections can be either:
o a branch name, or
o an asterisk, to match any branch;
The corresponding values can be either:
o a comma-separated list containing users and groups, or
o an asterisk, to match anyone;
You can add the "!" prefix to a user or group name to invert the sense of the match.
Path-based Access Control
Use the acl.deny and acl.allow sections to have path-based access control. Keys in these
sections accept a subtree pattern (with a glob syntax by default). The corresponding val-
ues follow the same syntax as the other sections above.
Bookmark-based Access Control
Use the acl.deny.bookmarks and acl.allow.bookmarks sections to have bookmark-based access
control. Keys in these sections can be either:
o a bookmark name, or
o an asterisk, to match any bookmark;
The corresponding values can be either:
o a comma-separated list containing users and groups, or
o an asterisk, to match anyone;
You can add the "!" prefix to a user or group name to invert the sense of the match.
Note: for interactions between clients and servers using Mercurial 3.6+ a rejection will
generally reject the entire push, for interactions involving older clients, the commit
transactions will already be accepted, and only the bookmark movement will be rejected.
Groups
Group names must be prefixed with an @ symbol. Specifying a group name has the same effect
as specifying all the users in that group.
You can define group members in the acl.groups section. If a group name is not defined
there, and Mercurial is running under a Unix-like system, the list of users will be taken
from the OS. Otherwise, an exception will be raised.
Example Configuration
[hooks]
# Use this if you want to check access restrictions at commit time
pretxncommit.acl = python:hgext.acl.hook
# Use this if you want to check access restrictions for pull, push,
# bundle and serve.
pretxnchangegroup.acl = python:hgext.acl.hook
[acl]
# Allow or deny access for incoming changes only if their source is
# listed here, let them pass otherwise. Source is "serve" for all
# remote access (http or ssh), "push", "pull" or "bundle" when the
# related commands are run locally.
# Default: serve
sources = serve
[acl.deny.branches]
# Everyone is denied to the frozen branch:
frozen-branch = *
# A bad user is denied on all branches:
* = bad-user
[acl.allow.branches]
# A few users are allowed on branch-a:
branch-a = user-1, user-2, user-3
# Only one user is allowed on branch-b:
branch-b = user-1
# The super user is allowed on any branch:
* = super-user
# Everyone is allowed on branch-for-tests:
branch-for-tests = *
[acl.deny]
# This list is checked first. If a match is found, acl.allow is not
# checked. All users are granted access if acl.deny is not present.
# Format for both lists: glob pattern = user, ..., @group, ...
# To match everyone, use an asterisk for the user:
# my/glob/pattern = *
# user6 will not have write access to any file:
** = user6
# Group "hg-denied" will not have write access to any file:
** = @hg-denied
# Nobody will be able to change "DONT-TOUCH-THIS.txt", despite
# everyone being able to change all other files. See below.
src/main/resources/DONT-TOUCH-THIS.txt = *
[acl.allow]
# if acl.allow is not present, all users are allowed by default
# empty acl.allow = no users allowed
# User "doc_writer" has write access to any file under the "docs"
# folder:
docs/** = doc_writer
# User "jack" and group "designers" have write access to any file
# under the "images" folder:
images/** = jack, @designers
# Everyone (except for "user6" and "@hg-denied" - see acl.deny above)
# will have write access to any file under the "resources" folder
# (except for 1 file. See acl.deny):
src/main/resources/** = *
.hgtags = release_engineer
Examples using the ! prefix
Suppose there's a branch that only a given user (or group) should be able to push to, and
you don't want to restrict access to any other branch that may be created.
The "!" prefix allows you to prevent anyone except a given user or group to push change-
sets in a given branch or path.
In the examples below, we will: 1) Deny access to branch "ring" to anyone but user "gol-
lum" 2) Deny access to branch "lake" to anyone but members of the group "hobbit" 3) Deny
access to a file to anyone but user "gollum"
[acl.allow.branches]
# Empty
[acl.deny.branches]
# 1) only 'gollum' can commit to branch 'ring';
# 'gollum' and anyone else can still commit to any other branch.
ring = !gollum
# 2) only members of the group 'hobbit' can commit to branch 'lake';
# 'hobbit' members and anyone else can still commit to any other branch.
lake = !@hobbit
# You can also deny access based on file paths:
[acl.allow]
# Empty
[acl.deny]
# 3) only 'gollum' can change the file below;
# 'gollum' and anyone else can still change any other file.
/misty/mountains/cave/ring = !gollum

[blackbox]
track = *
ignore = pythonhook
# dirty is *EXPENSIVE* (slow);
# each log entry indicates `+` if the repository is dirty, like :hg:`id`.
dirty = True
# record the source of log messages
logsource = True
[blackbox]
track = command, commandfinish, commandexception, exthook, pythonhook
[blackbox]

switch to bookmark
hg push -B .
push active bookmark
bugzilla
hooks for integrating with the Bugzilla bug tracker
This hook extension adds comments on bugs in Bugzilla when changesets that refer to bugs
by Bugzilla ID are seen. The comment is formatted using the Mercurial template mechanism.
The bug references can optionally include an update for Bugzilla of the hours spent work-
ing on the bug. Bugs can also be marked fixed.
Four basic modes of access to Bugzilla are provided:
1. Access via the Bugzilla REST-API. Requires bugzilla 5.0 or later.
2. Access via the Bugzilla XMLRPC interface. Requires Bugzilla 3.4 or later.
3. Check data via the Bugzilla XMLRPC interface and submit bug change via email to
Bugzilla email interface. Requires Bugzilla 3.4 or later.
4. Writing directly to the Bugzilla database. Only Bugzilla installations using MySQL are
supported. Requires Python MySQLdb.
Writing directly to the database is susceptible to schema changes, and relies on a
Bugzilla contrib script to send out bug change notification emails. This script runs as
the user running Mercurial, must be run on the host with the Bugzilla install, and re-
quires permission to read Bugzilla configuration details and the necessary MySQL user and
password to have full access rights to the Bugzilla database. For these reasons this ac-
cess mode is now considered deprecated, and will not be updated for new Bugzilla versions
going forward. Only adding comments is supported in this access mode.
Access via XMLRPC needs a Bugzilla username and password to be specified in the configura-
tion. Comments are added under that username. Since the configuration must be readable by
all Mercurial users, it is recommended that the rights of that user are restricted in
Bugzilla to the minimum necessary to add comments. Marking bugs fixed requires Bugzilla
4.0 and later.
Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends email to the Bugzilla
email interface to submit comments to bugs. The From: address in the email is set to the
email address of the Mercurial user, so the comment appears to come from the Mercurial
user. In the event that the Mercurial user email is not recognized by Bugzilla as a
Bugzilla user, the email associated with the Bugzilla username used to log into Bugzilla
is used instead as the source of the comment. Marking bugs fixed works on all supported
Bugzilla versions.
Access via the REST-API needs either a Bugzilla username and password or an apikey speci-
fied in the configuration. Comments are made under the given username or the user associ-
ated with the apikey in Bugzilla.
Configuration items common to all access modes:
bugzilla.version
The access type to use. Values recognized are:
restapi
Bugzilla REST-API, Bugzilla 5.0 and later.
xmlrpc
Bugzilla XMLRPC interface.
xmlrpc+email
Bugzilla XMLRPC and email interfaces.
3.0
MySQL access, Bugzilla 3.0 and later.
2.18
MySQL access, Bugzilla 2.18 and up to but not including 3.0.
2.16
MySQL access, Bugzilla 2.16 and up to but not including 2.18.
bugzilla.regexp
Regular expression to match bug IDs for update in changeset commit message. It
must contain one "()" named group <ids> containing the bug IDs separated by
non-digit characters. It may also contain a named group <hours> with a float-
ing-point number giving the hours worked on the bug. If no named groups are
present, the first "()" group is assumed to contain the bug IDs, and work time is
not updated. The default expression matches Bug 1234, Bug no. 1234, Bug number
1234, Bugs 1234,5678, Bug 1234 and 5678 and variations thereof, followed by an
hours number prefixed by h or hours, e.g. hours 1.5. Matching is case insensitive.
bugzilla.fixregexp
Regular expression to match bug IDs for marking fixed in changeset commit message.
This must contain a "()" named group <ids>` containing the bug IDs separated by
non-digit characters. It may also contain a named group ``<hours> with a float-
ing-point number giving the hours worked on the bug. If no named groups are
present, the first "()" group is assumed to contain the bug IDs, and work time is
not updated. The default expression matches Fixes 1234, Fixes bug 1234, Fixes bugs
1234,5678, Fixes 1234 and 5678 and variations thereof, followed by an hours number
prefixed by h or hours, e.g. hours 1.5. Matching is case insensitive.
bugzilla.fixstatus
The status to set a bug to when marking fixed. Default RESOLVED.
bugzilla.fixresolution
The resolution to set a bug to when marking fixed. Default FIXED.
bugzilla.style
The style file to use when formatting comments.
bugzilla.template
Template to use when formatting comments. Overrides style if specified. In addition
to the usual Mercurial keywords, the extension specifies:
{bug}
The Bugzilla bug ID.
{root}
The full pathname of the Mercurial repository.
{webroot}
Stripped pathname of the Mercurial repository.
{hgweb}
Base URL for browsing Mercurial repositories.
Default changeset {node|short} in repo {root} refers to bug {bug}.\nde-
tails:\n\t{desc|tabindent}
bugzilla.strip
The number of path separator characters to strip from the front of the Mercurial
repository path ({root} in templates) to produce {webroot}. For example, a reposi-
tory with {root} /var/local/my-project with a strip of 2 gives a value for {web-
root} of my-project. Default 0.
web.baseurl
Base URL for browsing Mercurial repositories. Referenced from templates as {hgweb}.
Configuration items common to XMLRPC+email and MySQL access modes:
bugzilla.usermap
Path of file containing Mercurial committer email to Bugzilla user email mappings.
If specified, the file should contain one mapping per line:
committer = Bugzilla user
See also the [usermap] section.
The [usermap] section is used to specify mappings of Mercurial committer email to Bugzilla
user email. See also bugzilla.usermap. Contains entries of the form committer = Bugzilla
user.
XMLRPC and REST-API access mode configuration:
bugzilla.bzurl
The base URL for the Bugzilla installation. Default http://localhost/bugzilla.
bugzilla.user
The username to use to log into Bugzilla via XMLRPC. Default bugs.
bugzilla.password
The password for Bugzilla login.
REST-API access mode uses the options listed above as well as:
bugzilla.apikey
An apikey generated on the Bugzilla instance for api access. Using an apikey re-
moves the need to store the user and password options.
XMLRPC+email access mode uses the XMLRPC access mode configuration items, and also:
bugzilla.bzemail
The Bugzilla email address.
In addition, the Mercurial email settings must be configured. See the documentation in
hgrc(5), sections [email] and [smtp].
MySQL access mode configuration:
bugzilla.host
Hostname of the MySQL server holding the Bugzilla database. Default localhost.
bugzilla.db
Name of the Bugzilla database in MySQL. Default bugs.

bugzilla.password
Password to use to access MySQL server.
bugzilla.timeout
Database connection timeout (seconds). Default 5.
bugzilla.bzuser
Fallback Bugzilla user name to record comments with, if changeset committer cannot
be found as a Bugzilla user.
bugzilla.bzdir
Bugzilla install directory. Used by default notify. Default /var/www/html/bugzilla.
bugzilla.notify
The command to run to get Bugzilla to send bug change notification emails. Substi-
tutes from a map with 3 keys, bzdir, id (bug id) and user (committer bugzilla
email). Default depends on version; from 2.18 it is "cd %(bzdir)s && perl -T con-
trib/sendbugmail.pl %(id)s %(user)s".

censor
erase file content at a given revision
The censor command instructs Mercurial to erase all content of a file at a given revision
without updating the changeset hash. This allows existing history to remain valid while
preventing future clones/pulls from receiving the erased data.
Typical uses for censor are due to security or legal requirements, including:
* Passwords, private keys, cryptographic material
* Licensed data/code/libraries for which the license has expired
* Personally Identifiable Information or other private data
Censored nodes can interrupt mercurial's typical operation whenever the excised data needs
to be materialized. Some commands, like hg cat/hg revert, simply fail when asked to pro-
duce censored data. Others, like hg verify and hg update, must be capable of tolerating
censored data to continue to function in a meaningful way. Such commands only tolerate
censored file revisions if they are allowed by the "censor.policy=ignore" config option.
A few informative commands such as hg grep will unconditionally ignore censored data and
merely report that it was encountered.
Commands
Repository maintenance
censor
hg censor -r REV [-t TEXT] [FILE]
Options:
-r,--rev <REV>
censor file from specified revision
-t,--tombstone <TEXT>
replacement tombstone data
children
command to display child changesets (DEPRECATED)
This extension is deprecated. You should use hg log -r "children(REV)" instead.
Commands
Change navigation
children
show the children of the given or working directory revision:
hg children [-r REV] [FILE]
Print the children of the working directory's revisions. If a revision is given via
-r/--rev, the children of that revision will be printed. If a file argument is given, re-
vision in which the file was last changed (after the working directory revision or the ar-
gument to --rev if given) is printed.
Please use hg log instead:
hg children => hg log -r "children(.)"
hg children -r REV => hg log -r "children(REV)"
See hg help log and hg help revsets.children.
Options:
-r,--rev <REV>
show children of the specified revision (default: .)
--style <STYLE>
display using template map file (DEPRECATED)
-T,--template <TEMPLATE>
display with template
churn
command to display statistics about repository history
Commands
Repository maintenance
churn
histogram of changes to the repository:
hg churn [-d DATE] [-r REV] [--aliases FILE] [FILE]
This command will display a histogram representing the number of changed lines or revi-
sions, grouped according to the given template. The default template will group changes by
author. The --dateformat option may be used to group the results by date instead.
Statistics are based on the number of changed lines, or alternatively the number of match-
ing revisions if the --changesets option is specified.
Examples:
# display count of changed lines for every committer
hg churn -T "{author|email}"
# display daily activity graph
hg churn -f "%H" -s -c
# display activity of developers by month
hg churn -f "%Y-%m" -s -c
# display count of lines changed in every year
hg churn -f "%Y" -s
# display count of lines changed in a time range
hg churn -d "2020-04 to 2020-09"
It is possible to map alternate email addresses to a main address by providing a file us-
ing the following format:
<alias email> = <actual email>
Such a file may be specified with the --aliases option, otherwise a .hgchurn file will be
looked for in the working directory root. Aliases will be split from the rightmost "=".
Options:
-r,--rev <REV[+]>
count rate for the specified revision or revset
-d,--date <DATE>
count rate for revisions matching date spec
-t,--oldtemplate <TEMPLATE>
template to group changesets (DEPRECATED)
-T,--template <TEMPLATE>
template to group changesets (default: {author|email})
-f,--dateformat <FORMAT>
strftime-compatible format for grouping by date
-c, --changesets
count rate by number of changesets
-s, --sort
sort by key (default: sort by count)
--diffstat
display added/removed lines separately
--aliases <FILE>
file with email aliases
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns

clonebundles
advertise pre-generated bundles to seed clones
"clonebundles" is a server-side extension used to advertise the existence of pre-gener-
ated, externally hosted bundle files to clients that are cloning so that cloning can be
faster, more reliable, and require less resources on the server. "pullbundles" is a re-
lated feature for sending pre-generated bundle files to clients as part of pull opera-
tions.
Cloning can be a CPU and I/O intensive operation on servers. Traditionally, the server, in
response to a client's request to clone, dynamically generates a bundle containing the en-
tire repository content and sends it to the client. There is no caching on the server and
the server will have to redundantly generate the same outgoing bundle in response to each
clone request. For servers with large repositories or with high clone volume, the load
from clones can make scaling the server challenging and costly.
This extension provides server operators the ability to offload potentially expensive
clone load to an external service. Pre-generated bundles also allow using more CPU inten-
sive compression, reducing the effective bandwidth requirements.
Here's how clone bundles work:
1. A server operator establishes a mechanism for making bundle files available on a host-
ing service where Mercurial clients can fetch them.
2. A manifest file listing available bundle URLs and some optional metadata is added to
the Mercurial repository on the server.
3. A client initiates a clone against a clone bundles aware server.
4. The client sees the server is advertising clone bundles and fetches the manifest list-
ing available bundles.
5. The client filters and sorts the available bundles based on what it supports and pre-
fers.
6. The client downloads and applies an available bundle from the server-specified URL.
7. The client reconnects to the original server and performs the equivalent of hg pull to
retrieve all repository data not in the bundle. (The repository could have been updated
between when the bundle was created and when the client started the clone.) This may
use "pullbundles".
Instead of the server generating full repository bundles for every clone request, it gen-
erates full bundles once and they are subsequently reused to bootstrap new clones. The
server may still transfer data at clone time. However, this is only data that has been
added/changed since the bundle was created. For large, established repositories, this can
reduce server load for clones to less than 1% of original.
Here's how pullbundles work:
1. A manifest file listing available bundles and describing the revisions is added to the
Mercurial repository on the server.
2. A new-enough client informs the server that it supports partial pulls and initiates a
pull.
3. If the server has pull bundles enabled and sees the client advertising partial pulls,
it checks for a matching pull bundle in the manifest. A bundle matches if the format
is supported by the client, the client has the required revisions already and needs
something from the bundle.
4. If there is at least one matching bundle, the server sends it to the client.
5. The client applies the bundle and notices that the server reply was incomplete. It ini-
tiates another pull.
To work, this extension requires the following of server operators:
o Generating bundle files of repository content (typically periodically, such as once per
day).
o Clone bundles: A file server that clients have network access to and that Python knows
how to talk to through its normal URL handling facility (typically an HTTP/HTTPS
server).
o A process for keeping the bundles manifest in sync with available bundle files.
Strictly speaking, using a static file hosting server isn't required: a server operator
could use a dynamic service for retrieving bundle data. However, static file hosting ser-
vices are simple and scalable and should be sufficient for most needs.
Bundle files can be generated with the hg bundle command. Typically hg bundle --all is
used to produce a bundle of the entire repository.
hg debugcreatestreamclonebundle can be used to produce a special streaming clonebundle.
These are bundle files that are extremely efficient to produce and consume (read: fast).
However, they are larger than traditional bundle formats and require that clients support
the exact set of repository data store formats in use by the repository that created them.
Typically, a newer server can serve data that is compatible with older clients. However,
streaming clone bundles don't have this guarantee. Server operators need to be aware that
newer versions of Mercurial may produce streaming clone bundles incompatible with older
Mercurial versions.
A server operator is responsible for creating a .hg/clonebundles.manifest file containing
the list of available bundle files suitable for seeding clones. If this file does not ex-
ist, the repository will not advertise the existence of clone bundles when clients con-
nect. For pull bundles, .hg/pullbundles.manifest is used.
The manifest file contains a newline (n) delimited list of entries.
Each line in this file defines an available bundle. Lines have the format:
<URL> [<key>=<value>[ <key>=<value>]]
That is, a URL followed by an optional, space-delimited list of key=value pairs describing
additional properties of this bundle. Both keys and values are URI encoded.
For pull bundles, the URL is a path under the .hg directory of the repository.
Keys in UPPERCASE are reserved for use by Mercurial and are defined below. All non-upper-
case keys can be used by site installations. An example use for custom properties is to
use the datacenter attribute to define which data center a file is hosted in. Clients
could then prefer a server in the data center closest to them.
The following reserved keys are currently defined:
BUNDLESPEC
A "bundle specification" string that describes the type of the bundle.
These are string values that are accepted by the "--type" argument of hg bundle.
The values are parsed in strict mode, which means they must be of the "<compres-
sion>-<type>" form. See mercurial.exchange.parsebundlespec() for more details.
hg debugbundle --spec can be used to print the bundle specification string for a
bundle file. The output of this command can be used verbatim for the value of
BUNDLESPEC (it is already escaped).
Clients will automatically filter out specifications that are unknown or unsup-
ported so they won't attempt to download something that likely won't apply.
The actual value doesn't impact client behavior beyond filtering: clients will
still sniff the bundle type from the header of downloaded files.
Use of this key is highly recommended, as it allows clients to easily skip unsup-
ported bundles. If this key is not defined, an old client may attempt to apply a
bundle that it is incapable of reading.
REQUIRESNI
Whether Server Name Indication (SNI) is required to connect to the URL. SNI allows
servers to use multiple certificates on the same IP. It is somewhat common in CDNs
and other hosting providers. Older Python versions do not support SNI. Defining
this attribute enables clients with older Python versions to filter this entry
without experiencing an opaque SSL failure at connection time.
If this is defined, it is important to advertise a non-SNI fallback URL or clients
running old Python releases may not be able to clone with the clonebundles facil-
ity.
Value should be "true".
REQUIREDRAM
Value specifies expected memory requirements to decode the payload. Values can
have suffixes for common bytes sizes. e.g. "64MB".
This key is often used with zstd-compressed bundles using a high compression level
/ window size, which can require 100+ MB of memory to decode.
heads Used for pull bundles. This contains the ; separated changeset hashes of the heads
of the bundle content.
bases Used for pull bundles. This contains the ; separated changeset hashes of the roots
of the bundle content. This can be skipped if the bundle was created without
--base.
Manifests can contain multiple entries. Assuming metadata is defined, clients will filter
entries from the manifest that they don't support. The remaining entries are optionally
sorted by client preferences (ui.clonebundleprefers config option). The client then at-
tempts to fetch the bundle at the first URL in the remaining list.
Errors when downloading a bundle will fail the entire clone operation: clients do not au-
tomatically fall back to a traditional clone. The reason for this is that if a server is
using clone bundles, it is probably doing so because the feature is necessary to help it
scale. In other words, there is an assumption that clone load will be offloaded to another
service and that the Mercurial server isn't responsible for serving this clone load. If
that other service experiences issues and clients start mass falling back to the original
Mercurial server, the added clone load could overwhelm the server due to unexpected load
and effectively take it offline. Not having clients automatically fall back to cloning
from the original server mitigates this scenario.
Because there is no automatic Mercurial server fallback on failure of the bundle hosting
service, it is important for server operators to view the bundle hosting service as an ex-
tension of the Mercurial server in terms of availability and service level agreements: if
the bundle hosting service goes down, so does the ability for clients to clone. Note:
clients will see a message informing them how to bypass the clone bundles facility when a
failure occurs. So server operators should prepare for some people to follow these in-
structions when a failure occurs, thus driving more load to the original Mercurial server
when the bundle hosting service fails.

convert
import revisions from foreign VCS repositories into Mercurial
Commands
Uncategorized commands
convert
convert a foreign SCM repository to a Mercurial one.:
hg convert [OPTION]... SOURCE [DEST [REVMAP]]
Accepted source formats [identifiers]:
o Mercurial [hg]
o CVS [cvs]
o Darcs [darcs]
o git [git]
o Subversion [svn]
o Monotone [mtn]
o GNU Arch [gnuarch]
o Bazaar [bzr]
o Perforce [p4]
Accepted destination formats [identifiers]:
o Mercurial [hg]
o Subversion [svn] (history on branches is not preserved)
If no revision is given, all revisions will be converted. Otherwise, convert will only
import up to the named revision (given in a format understood by the source).
If no destination directory name is specified, it defaults to the basename of the source
with -hg appended. If the destination repository doesn't exist, it will be created.
By default, all sources except Mercurial will use --branchsort. Mercurial uses --source-
sort to preserve original revision numbers order. Sort modes have the following effects:
--branchsort
convert from parent to child revision when possible, which means branches are usu-
ally converted one after the other. It generates more compact repositories.
--datesort
sort revisions by date. Converted repositories have good-looking changelogs but are
often an order of magnitude larger than the same ones generated by --branchsort.
--sourcesort
try to preserve source revisions order, only supported by Mercurial sources.
--closesort
try to move closed revisions as close as possible to parent branches, only sup-
ported by Mercurial sources.
If REVMAP isn't given, it will be put in a default location (<dest>/.hg/shamap by de-
fault). The REVMAP is a simple text file that maps each source commit ID to the destina-
tion ID for that revision, like so:
<source ID> <destination ID>
If the file doesn't exist, it's automatically created. It's updated on each commit copied,
so hg convert can be interrupted and can be run repeatedly to copy new commits.
The authormap is a simple text file that maps each source commit author to a destination
commit author. It is handy for source SCMs that use unix logins to identify authors (e.g.:
CVS). One line per author mapping and the line format is:
source author = destination author
Empty lines and lines starting with a # are ignored.
The filemap is a file that allows filtering and remapping of files and directories. Each
line can contain one of the following directives:
include path/to/file-or-dir
exclude path/to/file-or-dir
rename path/to/source path/to/destination
Comment lines start with #. A specified path matches if it equals the full relative name
of a file or one of its parent directories. The include or exclude directive with the
longest matching path applies, so line order does not matter.
The include directive causes a file, or all files under a directory, to be included in the
destination repository. The default if there are no include statements is to include ev-
erything. If there are any include statements, nothing else is included. The exclude di-
rective causes files or directories to be omitted. The rename directive renames a file or
directory if it is converted. To rename from a subdirectory into the root of the reposi-
tory, use . as the path to rename to.
--full will make sure the converted changesets contain exactly the right files with the
right content. It will make a full conversion of all files, not just the ones that have
changed. Files that already are correct will not be changed. This can be used to apply
filemap changes when converting incrementally. This is currently only supported for Mercu-
rial and Subversion.
The splicemap is a file that allows insertion of synthetic history, letting you specify
the parents of a revision. This is useful if you want to e.g. give a Subversion merge two
parents, or graft two disconnected series of history together. Each entry contains a key,
followed by a space, followed by one or two comma-separated values:
key parent1, parent2
The key is the revision ID in the source revision control system whose parents should be
modified (same format as a key in .hg/shamap). The values are the revision IDs (in either
the source or destination revision control system) that should be used as the new parents
for that node. For example, if you have merged "release-1.0" into "trunk", then you should
specify the revision on "trunk" as the first parent and the one on the "release-1.0"
branch as the second.
The branchmap is a file that allows you to rename a branch when it is being brought in
from whatever external repository. When used in conjunction with a splicemap, it allows
for a powerful combination to help fix even the most badly mismanaged repositories and
turn them into nicely structured Mercurial repositories. The branchmap contains lines of
the form:
original_branch_name new_branch_name
where "original_branch_name" is the name of the branch in the source repository, and
"new_branch_name" is the name of the branch is the destination repository. No whitespace
is allowed in the new branch name. This can be used to (for instance) move code in one
repository from "default" to a named branch.
Mercurial Source
The Mercurial source recognizes the following configuration options, which you can set on
the command line with --config:
convert.hg.ignoreerrors
ignore integrity errors when reading. Use it to fix Mercurial repositories with
missing revlogs, by converting from and to Mercurial. Default is False.
convert.hg.saverev
store original revision ID in changeset (forces target IDs to change). It takes a
boolean argument and defaults to False.
convert.hg.startrev
specify the initial Mercurial revision. The default is 0.
convert.hg.revs
revset specifying the source revisions to convert.
Bazaar Source
The following options can be used with --config:
convert.bzr.saverev
whether to store the original Bazaar commit ID in the metadata of the destination
commit. The default is True.
CVS Source
CVS source will use a sandbox (i.e. a checked-out copy) from CVS to indicate the starting
point of what will be converted. Direct access to the repository files is not needed, un-
less of course the repository is :local:. The conversion uses the top level directory in
the sandbox to find the CVS repository, and then uses CVS rlog commands to find files to
convert. This means that unless a filemap is given, all files under the starting directory
will be converted, and that any directory reorganization in the CVS sandbox is ignored.
The following options can be used with --config:
convert.cvsps.cache
Set to False to disable remote log caching, for testing and debugging purposes. De-
fault is True.
convert.cvsps.fuzz
Specify the maximum time (in seconds) that is allowed between commits with identi-
cal user and log message in a single changeset. When very large files were checked
in as part of a changeset then the default may not be long enough. The default is
60.
convert.cvsps.logencoding
Specify encoding name to be used for transcoding CVS log messages. Multiple encod-
ing names can be specified as a list (see hg help config.Syntax), but only the
first acceptable encoding in the list is used per CVS log entries. This transcoding
is executed before cvslog hook below.
convert.cvsps.mergeto
Specify a regular expression to which commit log messages are matched. If a match
occurs, then the conversion process will insert a dummy revision merging the branch
on which this log message occurs to the branch indicated in the regex. Default is
{{mergetobranch ([-\w]+)}}
convert.cvsps.mergefrom
Specify a regular expression to which commit log messages are matched. If a match
occurs, then the conversion process will add the most recent revision on the branch
indicated in the regex as the second parent of the changeset. Default is {{merge-
frombranch ([-\w]+)}}
convert.localtimezone
use local time (as determined by the TZ environment variable) for changeset
date/times. The default is False (use UTC).
hooks.cvslog
Specify a Python function to be called at the end of gathering the CVS log. The
function is passed a list with the log entries, and can modify the entries
in-place, or add or delete them.
hooks.cvschangesets
Specify a Python function to be called after the changesets are calculated from the
CVS log. The function is passed a list with the changeset entries, and can modify
the changesets in-place, or add or delete them.
An additional "debugcvsps" Mercurial command allows the builtin changeset merging code to
be run without doing a conversion. Its parameters and output are similar to that of cvsps
2.1. Please see the command help for more details.
Subversion Source
Subversion source detects classical trunk/branches/tags layouts. By default, the supplied
svn://repo/path/ source URL is converted as a single branch. If svn://repo/path/trunk ex-
ists it replaces the default branch. If svn://repo/path/branches exists, its subdirecto-
ries are listed as possible branches. If svn://repo/path/tags exists, it is looked for
tags referencing converted branches. Default trunk, branches and tags values can be over-
ridden with following options. Set them to paths relative to the source URL, or leave them
blank to disable auto detection.
The following options can be set with --config:
convert.svn.branches
specify the directory containing branches. The default is branches.
convert.svn.tags
specify the directory containing tags. The default is tags.
convert.svn.trunk
specify the name of the trunk branch. The default is trunk.
convert.localtimezone
use local time (as determined by the TZ environment variable) for changeset
date/times. The default is False (use UTC).
Source history can be retrieved starting at a specific revision, instead of being inte-
grally converted. Only single branch conversions are supported.
convert.svn.startrev
specify start Subversion revision number. The default is 0.
Git Source
The Git importer converts commits from all reachable branches (refs in refs/heads) and re-
motes (refs in refs/remotes) to Mercurial. Branches are converted to bookmarks with the
same name, with the leading 'refs/heads' stripped. Git submodules are converted to Git
subrepos in Mercurial.
The following options can be set with --config:
convert.git.similarity
specify how similar files modified in a commit must be to be imported as renames or
copies, as a percentage between 0 (disabled) and 100 (files must be identical). For
example, 90 means that a delete/add pair will be imported as a rename if more than
90% of the file hasn't changed. The default is 50.
convert.git.findcopiesharder
while detecting copies, look at all files in the working copy instead of just
changed ones. This is very expensive for large projects, and is only effective when
convert.git.similarity is greater than 0. The default is False.
convert.git.renamelimit
perform rename and copy detection up to this many changed files in a commit. In-
creasing this will make rename and copy detection more accurate but will signifi-
cantly slow down computation on large projects. The option is only relevant if con-
vert.git.similarity is greater than 0. The default is 400.
convert.git.committeractions
list of actions to take when processing author and committer values.
Git commits have separate author (who wrote the commit) and committer (who applied
the commit) fields. Not all destinations support separate author and committer
fields (including Mercurial). This config option controls what to do with these au-
thor and committer fields during conversion.
A value of messagedifferent will append a committer: ... line to the commit mes-
sage if the Git committer is different from the author. The prefix of that line can
be specified using the syntax messagedifferent=<prefix>. e.g. messagediffer-
ent=git-committer:. When a prefix is specified, a space will always be inserted
between the prefix and the value.
messagealways behaves like messagedifferent except it will always result in a com-
mitter: ... line being appended to the commit message. This value is mutually ex-
clusive with messagedifferent.
dropcommitter will remove references to the committer. Only references to the au-
thor will remain. Actions that add references to the committer will have no effect
when this is set.
replaceauthor will replace the value of the author field with the committer. Other
actions that add references to the committer will still take effect when this is
set.
The default is messagedifferent.
convert.git.extrakeys
list of extra keys from commit metadata to copy to the destination. Some Git repos-
itories store extra metadata in commits. By default, this non-default metadata
will be lost during conversion. Setting this config option can retain that meta-
data. Some built-in keys such as parent and branch are not allowed to be copied.
convert.git.remoteprefix
remote refs are converted as bookmarks with convert.git.remoteprefix as a prefix
followed by a /. The default is 'remote'.
convert.git.saverev
whether to store the original Git commit ID in the metadata of the destination com-
mit. The default is True.
convert.git.skipsubmodules
does not convert root level .gitmodules files or files with 160000 mode indicating
a submodule. Default is False.
Perforce Source
The Perforce (P4) importer can be given a p4 depot path or a client specification as
source. It will convert all files in the source to a flat Mercurial repository, ignoring
labels, branches and integrations. Note that when a depot path is given you then usually
should specify a target directory, because otherwise the target may be named ...-hg.
The following options can be set with --config:
convert.p4.encoding
specify the encoding to use when decoding standard output of the Perforce command
line tool. The default is default system encoding.
convert.p4.startrev
specify initial Perforce revision (a Perforce changelist number).
Mercurial Destination
The Mercurial destination will recognize Mercurial subrepositories in the destination di-
rectory, and update the .hgsubstate file automatically if the destination subrepositories
contain the <dest>/<sub>/.hg/shamap file. Converting a repository with subrepositories
requires converting a single repository at a time, from the bottom up.
An example showing how to convert a repository with subrepositories:
# so convert knows the type when it sees a non empty destination
$ hg init converted
$ hg convert orig/sub1 converted/sub1
$ hg convert orig/sub2 converted/sub2
$ hg convert orig converted
The following options are supported:
convert.hg.clonebranches
dispatch source branches in separate clones. The default is False.
convert.hg.tagsbranch
branch name for tag revisions, defaults to default.
convert.hg.usebranchnames
preserve branch names. The default is True.
convert.hg.sourcename
records the given string as a 'convert_source' extra value on each commit made in
the target repository. The default is None.
convert.hg.preserve-hash
only works with mercurial sources. Make convert prevent performance improvement to
the list of modified files in commits when such an improvement would cause the hash
of a commit to change. The default is False.
All Destinations
All destination types accept the following options:
convert.skiptags
does not convert tags from the source repo to the target repo. The default is
False.
Subversion Destination
Original commit dates are not preserved by default.
convert.svn.dangerous-set-commit-dates
preserve original commit dates, forcefully setting svn:date revision properties.
This option is DANGEROUS and may break some subversion functionality for the re-
sulting repository (e.g. filtering revisions with date ranges in svn log), as orig-
inal commit dates are not guaranteed to be monotonically increasing.
For commit dates setting to work destination repository must have pre-revprop-change hook
configured to allow setting of svn:date revision properties. See Subversion documentation
for more details.

eol
automatically manage newlines in repository files
This extension allows you to manage the type of line endings (CRLF or LF) that are used in
the repository and in the local working directory. That way you can get CRLF line endings
on Windows and LF on Unix/Mac, thereby letting everybody use their OS native line endings.
The extension reads its configuration from a versioned .hgeol configuration file found in
the root of the working directory. The .hgeol file use the same syntax as all other Mercu-
rial configuration files. It uses two sections, [patterns] and [repository].
The [patterns] section specifies how line endings should be converted between the working
directory and the repository. The format is specified by a file pattern. The first match
is used, so put more specific patterns first. The available line endings are LF, CRLF, and
BIN.
Files with the declared format of CRLF or LF are always checked out and stored in the
repository in that format and files declared to be binary (BIN) are left unchanged. Addi-
tionally, native is an alias for checking out in the platform's default line ending: LF on
Unix (including Mac OS X) and CRLF on Windows. Note that BIN (do nothing to line endings)
is Mercurial's default behavior; it is only needed if you need to override a later, more
general pattern.
The optional [repository] section specifies the line endings to use for files stored in
the repository. It has a single setting, native, which determines the storage line endings
for files declared as native in the [patterns] section. It can be set to LF or CRLF. The
default is LF. For example, this means that on Windows, files configured as native (CRLF
by default) will be converted to LF when stored in the repository. Files declared as LF,
CRLF, or BIN in the [patterns] section are always stored as-is in the repository.
Example versioned .hgeol file:
[patterns]
**.py = native
**.vcproj = CRLF
**.txt = native
Makefile = LF
**.jpg = BIN
[repository]
native = LF
Note The rules will first apply when files are touched in the working directory, e.g. by
updating to null and back to tip to touch all files.
The extension uses an optional [eol] section read from both the normal Mercurial configu-
ration files and the .hgeol file, with the latter overriding the former. You can use that
section to control the overall behavior. There are three settings:
o eol.native (default os.linesep) can be set to LF or CRLF to override the default inter-
pretation of native for checkout. This can be used with hg archive on Unix, say, to gen-
erate an archive where files have line endings for Windows.
o eol.only-consistent (default True) can be set to False to make the extension convert
files with inconsistent EOLs. Inconsistent means that there is both CRLF and LF present
in the file. Such files are normally not touched under the assumption that they have
mixed EOLs on purpose.
o eol.fix-trailing-newline (default False) can be set to True to ensure that converted
files end with a EOL character (either \n or \r\n as per the configured patterns).
The extension provides cleverencode: and cleverdecode: filters like the deprecated
win32text extension does. This means that you can disable win32text and enable eol and
your filters will still work. You only need to these filters until you have prepared a
.hgeol file.
The win32text.forbid* hooks provided by the win32text extension have been unified into a
single hook named eol.checkheadshook. The hook will lookup the expected line endings from
the .hgeol file, which means you must migrate to a .hgeol file first before using the
hook. eol.checkheadshook only checks heads, intermediate invalid revisions will be pushed.
To forbid them completely, use the eol.checkallhook hook. These hooks are best used as
pretxnchangegroup hooks.
See hg help patterns for more information about the glob patterns used.
extdiff
command to allow external programs to compare revisions
The extdiff Mercurial extension allows you to use external programs to compare revisions,
or revision with working directory. The external diff programs are called with a config-
urable set of options and two non-option arguments: paths to directories containing snap-
shots of files to compare.
If there is more than one file being compared and the "child" revision is the working di-
rectory, any modifications made in the external diff program will be copied back to the
working directory from the temporary directory.
The extdiff extension also allows you to configure new diff commands, so you do not need
to type hg extdiff -p kdiff3 always.
[extdiff]
# add new command that runs GNU diff(1) in 'context diff' mode
cdiff = gdiff -Nprc5
## or the old way:
#cmd.cdiff = gdiff
#opts.cdiff = -Nprc5
# add new command called meld, runs meld (no need to name twice). If
# the meld executable is not available, the meld tool in [merge-tools]
# will be used, if available
meld =
# add new command called vimdiff, runs gvimdiff with DirDiff plugin
# (see http://www.vim.org/scripts/script.php?script_id=102) Non
# English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
# your .vimrc
vimdiff = gvim -f "+next" \
"+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"
Tool arguments can include variables that are expanded at runtime:
$parent1, $plabel1 - filename, descriptive label of first parent
$child, $clabel - filename, descriptive label of child revision
$parent2, $plabel2 - filename, descriptive label of second parent
$root - repository root
$parent is an alias for $parent1.
The extdiff extension will look in your [diff-tools] and [merge-tools] sections for diff
tool arguments, when none are specified in [extdiff].
[extdiff]
kdiff3 =
[diff-tools]
kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
If a program has a graphical interface, it might be interesting to tell Mercurial about
it. It will prevent the program from being mistakenly used in a terminal-only environment
(such as an SSH terminal session), and will make hg extdiff --per-file open multiple file
diffs at once instead of one by one (if you still want to open file diffs one by one, you
can use the --confirm option).
Declaring that a tool has a graphical interface can be done with the gui flag next to
where diffargs are specified:
[diff-tools]
kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
kdiff3.gui = true
You can use -I/-X and list of file or directory names like normal hg diff command. The
extdiff extension makes snapshots of only needed files, so running the external diff pro-
gram will actually be pretty fast (at least faster than having to compare the entire
tree).
Commands
File content management
extdiff
use external program to diff repository (or selected files):
hg extdiff [OPT]... [FILE]...
Show differences between revisions for the specified files, using an external program. The
default program used is diff, with default options "-Npru".
To select a different program, use the -p/--program option. The program will be passed the
names of two directories to compare, unless the --per-file option is specified (see be-
low). To pass additional options to the program, use -o/--option. These will be passed be-
fore the names of the directories or files to compare.
The --from, --to, and --change options work the same way they do for hg diff.
The --per-file option runs the external program repeatedly on each file to diff, instead
of once on two directories. By default, this happens one by one, where the next file diff
is open in the external program only once the previous external program (for the previous
file diff) has exited. If the external program has a graphical interface, it can open all
the file diffs at once instead of one by one. See hg help -e extdiff for information about
how to tell Mercurial that a given program has a graphical interface.
The --confirm option will prompt the user before each invocation of the external program.
It is ignored if --per-file isn't specified.

factotum
http authentication with factotum
This extension allows the factotum(4) facility on Plan 9 from Bell Labs platforms to pro-
vide authentication information for HTTP access. Configuration entries specified in the
auth section as well as authentication information provided in the repository URL are
fully supported. If no prefix is specified, a value of "*" will be assumed.
By default, keys are specified as:
proto=pass service=hg prefix=<prefix> user=<username> !password=<password>
If the factotum extension is unable to read the required key, one will be requested inter-
actively.
A configuration section is available to customize runtime behavior. By default, these en-
tries are:
[factotum]
executable = /bin/auth/factotum
mountpoint = /mnt/factotum
service = hg
The executable entry defines the full path to the factotum binary. The mountpoint entry
defines the path to the factotum file service. Lastly, the service entry controls the ser-
vice name used when reading keys.
fastannotate
yet another annotate implementation that might be faster (EXPERIMENTAL)
The fastannotate extension provides a 'fastannotate' command that makes use of the linelog
data structure as a cache layer and is expected to be faster than the vanilla 'annotate'
if the cache is present.
In most cases, fastannotate requires a setup that mainbranch is some pointer that always
moves forward, to be most efficient.
Using fastannotate together with linkrevcache would speed up building the annotate cache
greatly. Run "debugbuildlinkrevcache" before "debugbuildannotatecache".
[fastannotate]
# specify the main branch head. the internal linelog will only contain
# the linear (ignoring p2) "mainbranch". since linelog cannot move
# backwards without a rebuild, this should be something that always moves
# forward, usually it is "master" or "@".
mainbranch = master
# fastannotate supports different modes to expose its feature.
# a list of combination:
# - fastannotate: expose the feature via the "fastannotate" command which
# deals with everything in a most efficient way, and provides extra
# features like --deleted etc.
# - fctx: replace fctx.annotate implementation. note:
# a. it is less efficient than the "fastannotate" command
# b. it will make it practically impossible to access the old (disk
# side-effect free) annotate implementation
# c. it implies "hgweb".
# - hgweb: replace hgweb's annotate implementation. conflict with "fctx".
# (default: fastannotate)
modes = fastannotate
# default format when no format flags are used (default: number)
defaultformat = changeset, user, date
# serve the annotate cache via wire protocol (default: False)
# tip: the .hg/fastannotate directory is portable - can be rsynced
server = True
# build annotate cache on demand for every client request (default: True)
# disabling it could make server response faster, useful when there is a
# cronjob building the cache.
serverbuildondemand = True
# update local annotate cache from remote on demand
client = False
# path to use when connecting to the remote server (default: default)
remotepath = default
# minimal length of the history of a file required to fetch linelog from
# the server. (default: 10)
clientfetchthreshold = 10
# for "fctx" mode, always follow renames regardless of command line option.
# this is a BC with the original command but will reduced the space needed
# for annotate cache, and is useful for client-server setup since the
# server will only provide annotate cache with default options (i.e. with
# follow). do not affect "fastannotate" mode. (default: True)
forcefollow = True
# for "fctx" mode, always treat file as text files, to skip the "isbinary"
# check. this is consistent with the "fastannotate" command and could help
# to avoid a file fetch if remotefilelog is used. (default: True)
forcetext = True
# use unfiltered repo for better performance.
unfilteredrepo = True
# sacrifice correctness in some corner cases for performance. it does not
# affect the correctness of the annotate cache being built. the option
# is experimental and may disappear in the future (default: False)

Commands
Remote repository management
fetch
pull changes from a remote repository, merge new changes if needed.:
hg fetch [SOURCE]
This finds all changes from the repository at the specified path or URL and adds them to
the local repository.
If the pulled changes add a new branch head, the head is automatically merged, and the re-
sult of the merge is committed. Otherwise, the working directory is updated to include
the new changes.
When a merge is needed, the working directory is first updated to the newly pulled
changes. Local changes are then merged into the pulled changes. To switch the merge order,
use --switch-parent.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success.

fix
rewrite file content in changesets or working copy (EXPERIMENTAL)
Provides a command that runs configured tools on the contents of modified files, writing
back any fixes to the working copy or replacing changesets.
Here is an example configuration that causes hg fix to apply automatic formatting fixes to
modified lines in C++ code:
[fix]
clang-format:command=clang-format --assume-filename={rootpath}
clang-format:linerange=--lines={first}:{last}
clang-format:pattern=set:**.cpp or **.hpp
The :command suboption forms the first part of the shell command that will be used to fix
a file. The content of the file is passed on standard input, and the fixed file content is
expected on standard output. Any output on standard error will be displayed as a warning.
If the exit status is not zero, the file will not be affected. A placeholder warning is
displayed if there is a non-zero exit status but no standard error output. Some values may
be substituted into the command:
{rootpath} The path of the file being fixed, relative to the repo root
{basename} The name of the file being fixed, without the directory path
If the :linerange suboption is set, the tool will only be run if there are changed lines
in a file. The value of this suboption is appended to the shell command once for every
range of changed lines in the file. Some values may be substituted into the command:
{first} The 1-based line number of the first line in the modified range
{last} The 1-based line number of the last line in the modified range
Deleted sections of a file will be ignored by :linerange, because there is no correspond-
ing line range in the version being fixed.
By default, tools that set :linerange will only be executed if there is at least one
changed line range. This is meant to prevent accidents like running a code formatter in
such a way that it unexpectedly reformats the whole file. If such a tool needs to operate
on unchanged files, it should set the :skipclean suboption to false.
The :pattern suboption determines which files will be passed through each configured tool.
See hg help patterns for possible values. However, all patterns are relative to the repo
root, even if that text says they are relative to the current working directory. If there
are file arguments to hg fix, the intersection of these patterns is used.
There is also a configurable limit for the maximum size of file that will be processed by
hg fix:
[fix]
maxfilesize = 2MB
Normally, execution of configured tools will continue after a failure (indicated by a
non-zero exit status). It can also be configured to abort after the first such failure, so
that no files will be affected if any tool fails. This abort will also cause hg fix to
exit with a non-zero status:
[fix]
failure = abort
When multiple tools are configured to affect a file, they execute in an order defined by
the :priority suboption. The priority suboption has a default value of zero for each tool.
Tools are executed in order of descending priority. The execution order of tools with
equal priority is unspecified. For example, you could use the 'sort' and 'head' utilities
to keep only the 10 smallest numbers in a text file by ensuring that 'sort' runs before
'head':
[fix]
sort:command = sort -n
head:command = head -n 10
sort:pattern = numbers.txt
head:pattern = numbers.txt
sort:priority = 2
head:priority = 1
To account for changes made by each tool, the line numbers used for incremental formatting
are recomputed before executing the next tool. So, each tool may see different values for
the arguments added by the :linerange suboption.
Each fixer tool is allowed to return some metadata in addition to the fixed file content.
The metadata must be placed before the file content on stdout, separated from the file
content by a zero byte. The metadata is parsed as a JSON value (so, it should be UTF-8 en-
coded and contain no zero bytes). A fixer tool is expected to produce this metadata encod-
ing if and only if the :metadata suboption is true:
[fix]
tool:command = tool --prepend-json-metadata
tool:metadata = true
The metadata values are passed to hooks, which can be used to print summaries or perform
other post-fixing work. The supported hooks are:
"postfixfile"
Run once for each file in each revision where any fixer tools made changes
to the file content. Provides "$HG_REV" and "$HG_PATH" to identify the file,
and "$HG_METADATA" with a map of fixer names to metadata values from fixer
tools that affected the file. Fixer tools that didn't affect the file have a
value of None. Only fixer tools that executed are present in the metadata.
"postfix"
Run once after all files and revisions have been handled. Provides
"$HG_REPLACEMENTS" with information about what revisions were created and
made obsolete. Provides a boolean "$HG_WDIRWRITTEN" to indicate whether any
files in the working copy were updated. Provides a list "$HG_METADATA"
mapping fixer tool names to lists of metadata values returned from
executions that modified a file. This aggregates the same metadata
previously passed to the "postfixfile" hook.
Fixer tools are run in the repository's root directory. This allows them to read configu-
ration files from the working copy, or even write to the working copy. The working copy
is not updated to match the revision being fixed. In fact, several revisions may be fixed
in parallel. Writes to the working copy are not amended into the revision being fixed;
fixer tools should always write fixed file content back to stdout as documented above.
Commands
File content management
fix
rewrite file content in changesets or working directory:
hg fix [OPTION]... [FILE]...
Runs any configured tools to fix the content of files. Only affects files with changes,
unless file arguments are provided. Only affects changed lines of files, unless the
--whole flag is used. Some tools may always affect the whole file regardless of --whole.
If --working-dir is used, files with uncommitted changes in the working copy will be
fixed. Note that no backup are made.
If revisions are specified with --source, those revisions and their descendants will be
checked, and they may be replaced with new revisions that have fixed file content. By au-
tomatically including the descendants, no merging, rebasing, or evolution will be re-
quired. If an ancestor of the working copy is included, then the working copy itself will
also be fixed, and the working copy will be updated to the fixed parent.
When determining what lines of each file to fix at each revision, the whole set of revi-
sions being fixed is considered, so that fixes to earlier revisions are not forgotten in
later ones. The --base flag can be used to override this default behavior, though it is
not usually desirable to do so.
Options:
--all fix all non-public non-obsolete revisions
--base <REV[+]>
revisions to diff against (overrides automatic selection, and applies to every re-
vision being fixed)
-r,--rev <REV[+]>
revisions to fix (ADVANCED)
-s,--source <REV[+]>
fix the specified revisions and their descendants
-w, --working-dir
fix the working directory
--whole
always fix every line of a file

fsmonitor
Faster status operations with the Watchman file monitor (EXPERIMENTAL)
Integrates the file-watching program Watchman with Mercurial to produce faster status re-
sults.
On a particular Linux system, for a real-world repository with over 400,000 files hosted
on ext4, vanilla hg status takes 1.3 seconds. On the same system, with fsmonitor it takes
about 0.3 seconds.
fsmonitor requires no configuration -- it will tell Watchman about your repository as nec-
essary. You'll need to install Watchman from https://facebook.github.io/watchman/ and make
sure it is in your PATH.
fsmonitor is incompatible with the largefiles and eol extensions, and will disable itself
if any of those are active.
The following configuration options exist:
[fsmonitor]
mode = {off, on, paranoid}
When mode = off, fsmonitor will disable itself (similar to not loading the extension at
all). When mode = on, fsmonitor will be enabled (the default). When mode = paranoid, fs-
monitor will query both Watchman and the filesystem, and ensure that the results are con-
sistent.
[fsmonitor]
timeout = (float)
A value, in seconds, that determines how long fsmonitor will wait for Watchman to return
results. Defaults to 2.0.
[fsmonitor]
blacklistusers = (list of userids)
A list of usernames for which fsmonitor will disable itself altogether.
[fsmonitor]
walk_on_invalidate = (boolean)
Whether or not to walk the whole repo ourselves when our cached state has been invali-
dated, for example when Watchman has been restarted or .hgignore rules have been changed.
Walking the repo in that case can result in competing for I/O with Watchman. For large re-
pos it is recommended to set this value to false. You may wish to set this to true if you
have a very fast filesystem that can outpace the IPC overhead of getting the result data
for the full repo from Watchman. Defaults to false.
[fsmonitor]
warn_when_unused = (boolean)
Whether to print a warning during certain operations when fsmonitor would be beneficial to
performance but isn't enabled.
[fsmonitor]
warn_update_file_count = (integer)
# or when mercurial is built with rust support
warn_update_file_count_rust = (integer)
If warn_when_unused is set and fsmonitor isn't enabled, a warning will be printed during
working directory updates if this many files will be created.

hgk
browse the repository in a graphical way
The hgk extension allows browsing the history of a repository in a graphical way. It re-
quires Tcl/Tk version 8.4 or later. (Tcl/Tk is not distributed with Mercurial.)
hgk consists of two parts: a Tcl script that does the displaying and querying of informa-
tion, and an extension to Mercurial named hgk.py, which provides hooks for hgk to get in-
formation. hgk can be found in the contrib directory, and the extension is shipped in the
hgext repository, and needs to be enabled.
The hg view command will launch the hgk Tcl script. For this command to work, hgk must be
in your search path. Alternately, you can specify the path to hgk in your configuration
file:
[hgk]
path = /location/of/hgk
hgk can make use of the extdiff extension to visualize revisions. Assuming you had al-
ready configured extdiff vdiff command, just add:
[hgk]
vdiff=vdiff
Revisions context menu will now display additional entries to fire vdiff on hovered and
selected revisions.
Commands

highlight
syntax highlighting for hgweb (requires Pygments)
It depends on the Pygments syntax highlighting library: http://pygments.org/
There are the following configuration options:
[web]
pygments_style = <style> (default: colorful)
highlightfiles = <fileset> (default: size('<5M'))
highlightonlymatchfilename = <bool> (default False)
highlightonlymatchfilename will only highlight files if their type could be identified by
their filename. When this is not enabled (the default), Pygments will try very hard to
identify the file type from content and any match (even matches with a low confidence
score) will be used.
histedit
interactive history editing
With this extension installed, Mercurial gains one new command: histedit. Usage is as fol-
lows, assuming the following history:
@ 3[tip] 7c2fd3b9020c 2009-04-27 18:04 -0500 durin42
| Add delta
|
o 2 030b686bedc4 2009-04-27 18:04 -0500 durin42
| Add gamma
|
o 1 c561b4e977df 2009-04-27 18:04 -0500 durin42
| Add beta
|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
If you were to run hg histedit c561b4e977df, you would see the following file open in your
editor:
pick c561b4e977df Add beta
pick 030b686bedc4 Add gamma
pick 7c2fd3b9020c Add delta
# Edit history between c561b4e977df and 7c2fd3b9020c
#
# Commits are listed from least to most recent
#
# Commands:
# p, pick = use commit
# e, edit = use commit, but allow edits before making new commit
# f, fold = use commit, but combine it with the one above
# r, roll = like fold, but discard this commit's description and date
# d, drop = remove commit from history
# m, mess = edit commit message without changing commit content
# b, base = checkout changeset and apply further changesets from there
#
In this file, lines beginning with # are ignored. You must specify a rule for each revi-
sion in your history. For example, if you had meant to add gamma before beta, and then
wanted to add delta in the same revision as beta, you would reorganize the file to look
like this:
pick 030b686bedc4 Add gamma
pick c561b4e977df Add beta
fold 7c2fd3b9020c Add delta
# Edit history between c561b4e977df and 7c2fd3b9020c
#
# Commits are listed from least to most recent
#
# Commands:
# p, pick = use commit
# e, edit = use commit, but allow edits before making new commit
# f, fold = use commit, but combine it with the one above
# r, roll = like fold, but discard this commit's description and date
# d, drop = remove commit from history
# m, mess = edit commit message without changing commit content
# b, base = checkout changeset and apply further changesets from there
#
At which point you close the editor and histedit starts working. When you specify a fold
operation, histedit will open an editor when it folds those revisions together, offering
you a chance to clean up the commit message:
Add beta
***
Add delta
Edit the commit message to your liking, then close the editor. The date used for the com-
mit will be the later of the two commits' dates. For this example, let's assume that the
commit message was changed to Add beta and delta. After histedit has run and had a chance
to remove any old or temporary revisions it needed, the history looks like this:
@ 2[tip] 989b4d060121 2009-04-27 18:04 -0500 durin42
| Add beta and delta.
|
o 1 081603921c3f 2009-04-27 18:04 -0500 durin42
| Add gamma
|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
Note that histedit does not remove any revisions (even its own temporary ones) until after
it has completed all the editing operations, so it will probably perform several strip op-
erations when it's done. For the above example, it had to run strip twice. Strip can be
slow depending on a variety of factors, so you might need to be a little patient. You can
choose to keep the original revisions by passing the --keep flag.
The edit operation will drop you back to a command prompt, allowing you to edit files
freely, or even use hg record to commit some changes as a separate commit. When you're
done, any remaining uncommitted changes will be committed as well. When done, run hg
histedit --continue to finish this step. If there are uncommitted changes, you'll be
prompted for a new commit message, but the default commit message will be the original
message for the edit ed revision, and the date of the original commit will be preserved.
The message operation will give you a chance to revise a commit message without changing
the contents. It's a shortcut for doing edit immediately followed by hg histedit --con-
tinue`.
If histedit encounters a conflict when moving a revision (while handling pick or fold),
it'll stop in a similar manner to edit with the difference that it won't prompt you for a
commit message when done. If you decide at this point that you don't like how much work it
will be to rearrange history, or that you made a mistake, you can use hg histedit --abort
to abandon the new changes you have made and return to the state before you attempted to
edit your history.
If we clone the histedit-ed example repository above and add four more changes, such that
we have the following history:
@ 6[tip] 038383181893 2009-04-27 18:04 -0500 stefan
| Add theta
|
o 5 140988835471 2009-04-27 18:04 -0500 stefan
| Add eta
|
o 4 122930637314 2009-04-27 18:04 -0500 stefan

o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
If you run hg histedit --outgoing on the clone then it is the same as running hg histedit
836302820282. If you need plan to push to a repository that Mercurial does not detect to
be related to the source repo, you can add a --force option.
Config
Histedit rule lines are truncated to 80 characters by default. You can customize this be-
havior by setting a different length in your configuration file:
[histedit]
linelen = 120 # truncate rule lines at 120 characters
The summary of a change can be customized as well:
[histedit]
summary-template = '{rev} {bookmarks} {desc|firstline}'
The customized summary should be kept short enough that rule lines will fit in the config-
ured line length. See above if that requires customization.
hg histedit attempts to automatically choose an appropriate base revision to use. To
change which base revision is used, define a revset in your configuration file:
[histedit]
defaultrev = only(.) & draft()
By default each edited revision needs to be present in histedit commands. To remove revi-
sion you need to use drop operation. You can configure the drop to be implicit for missing
commits by adding:
[histedit]
dropmissing = True
By default, histedit will close the transaction after each action. For performance pur-
poses, you can configure histedit to use a single transaction across the entire histedit.
WARNING: This setting introduces a significant risk of losing the work you've done in a
histedit if the histedit aborts unexpectedly:
[histedit]
singletransaction = True
Commands
Change manipulation
histedit
interactively edit changeset history:
hg histedit [OPTIONS] ([ANCESTOR] | --outgoing [URL])
This command lets you edit a linear series of changesets (up to and including the working
directory, which should be clean). You can:
o pick to [re]order a changeset
o drop to omit changeset
o mess to reword the changeset commit message
o fold to combine it with the preceding changeset (using the later date)
o roll like fold, but discarding this commit's description and date
o edit to edit this changeset (preserving date)
o base to checkout changeset and apply further changesets from there
There are a number of ways to select the root changeset:
o Specify ANCESTOR directly
o Use --outgoing -- it will be the first linear changeset not included in destination.
(See hg help config.paths.default-push)
o Otherwise, the value from the "histedit.defaultrev" config option is used as a revset to
select the base revision when ANCESTOR is not specified. The first revision returned by
the revset is used. By default, this selects the editable history that is unique to the
ancestry of the working directory.
If you use --outgoing, this command will abort if there are ambiguous outgoing revisions.
For example, if there are multiple branches containing outgoing revisions.
Use "min(outgoing() and ::.)" or similar revset specification instead of --outgoing to
specify edit target revision exactly in such ambiguous situation. See hg help revsets for
detail about selecting revisions.
Examples:
o A number of changes have been made. Revision 3 is no longer needed.
Start history editing from revision 3:
hg histedit -r 3
An editor opens, containing the list of revisions, with specific actions specified:
pick 5339bf82f0ca 3 Zworgle the foobar
pick 8ef592ce7cc4 4 Bedazzle the zerlog
pick 0a9639fcda9d 5 Morgify the cromulancy
Additional information about the possible actions to take appears below the list of
revisions.
To remove revision 3 from the history, its action (at the beginning of the relevant
line) is changed to 'drop':
drop 5339bf82f0ca 3 Zworgle the foobar
pick 8ef592ce7cc4 4 Bedazzle the zerlog
pick 0a9639fcda9d 5 Morgify the cromulancy
o A number of changes have been made. Revision 2 and 4 need to be swapped.
Start history editing from revision 2:
hg histedit -r 2
An editor opens, containing the list of revisions, with specific actions specified:
pick 252a1af424ad 2 Blorb a morgwazzle
pick 5339bf82f0ca 3 Zworgle the foobar
pick 8ef592ce7cc4 4 Bedazzle the zerlog
To swap revision 2 and 4, its lines are swapped in the editor:
pick 8ef592ce7cc4 4 Bedazzle the zerlog
pick 5339bf82f0ca 3 Zworgle the foobar
pick 252a1af424ad 2 Blorb a morgwazzle
Returns 0 on success, 1 if user intervention is required (not only for intentional "edit"
command, but also for resolving unexpected conflicts).
Options:
--commands <FILE>
read history edits from the specified file
-c, --continue
continue an edit already in progress
--edit-plan

-k, --keep
don't strip old nodes after edit is complete
--abort

hooklib
collection of simple hooks for common tasks (EXPERIMENTAL)
This extension provides a number of simple hooks to handle issues commonly found in repos-
itories with many contributors: - email notification when changesets move from draft to
public phase - email notification when changesets are obsoleted - enforcement of draft
phase for all incoming changesets - enforcement of a no-branch-merge policy - enforcement
of a no-multiple-heads policy
The implementation of the hooks is subject to change, e.g. whether to implement them as
individual hooks or merge them into the notify extension as option. The functionality it-
self is planned to be supported long-term.
infinitepush
store some pushes in a remote blob store on the server (EXPERIMENTAL)
IMPORTANT: if you use this extension, please contact mercurial-devel AT mercurial-scm.org
ASAP. This extension is believed to be unused and barring learning of users of this func-
tionality, we will delete this code at the end of 2020.

journal
track previous positions of bookmarks (EXPERIMENTAL)
This extension adds a new command: hg journal, which shows you where bookmarks were previ-
ously located.
Commands
Change organization
journal
show the previous position of bookmarks and the working copy:
hg journal [OPTION]... [BOOKMARKNAME]
The journal is used to see the previous commits that bookmarks and the working copy
pointed to. By default the previous locations for the working copy. Passing a bookmark
name will show all the previous positions of that bookmark. Use the --all switch to show
previous locations for all bookmarks and the working copy; each line will then include the
bookmark name, or '.' for the working copy, as well.
If name starts with re:, the remainder of the name is treated as a regular expression. To
match a name that actually starts with re:, use the prefix literal:.
By default hg journal only shows the commit hash and the command that was running at that
time. -v/--verbose will show the prior hash, the user, and the time at which it happened.
Use -c/--commits to output log information on each commit hash; at this point you can use
the usual --patch, --git, --stat and --template switches to alter the log output for
these.
hg journal -T json can be used to produce machine readable output.
Options:
--all show history for all names
-c, --commits
show commit metadata
-p, --patch
show patch
-g, --git
use git extended diff format
-l,--limit <NUM>
limit number of changes displayed
--stat output diffstat-style summary of changes
--style <STYLE>
display using template map file (DEPRECATED)
-T,--template <TEMPLATE>
display with template
keyword
expand keywords in tracked files
This extension expands RCS/CVS-like or self-customized $Keywords$ in tracked text files
selected by your configuration.
Keywords are only expanded in local repositories and not stored in the change history. The
mechanism can be regarded as a convenience for the current user or for archive distribu-
tion.
Keywords expand to the changeset data pertaining to the latest change relative to the
working directory parent of each file.
Configuration is done in the [keyword], [keywordset] and [keywordmaps] sections of hgrc
files.
Example:
[keyword]
# expand keywords in every python file except those matching "x*"
**.py =
x* = ignore
[keywordset]
# prefer svn- over cvs-like default keywordmaps
svn = True
Note The more specific you are in your filename patterns the less you lose speed in huge
repositories.
For [keywordmaps] template mapping and expansion demonstration and control run hg kwdemo.
See hg help templates for a list of available templates and filters.
Three additional date template filters are provided:
utcdate
"2006/09/18 15:13:13"
svnutcdate
"2006-09-18 15:13:13Z"
svnisodate
"2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"
The default template mappings (view with hg kwdemo -d) can be replaced with customized
keywords and templates. Again, run hg kwdemo to control the results of your configuration
changes.
Before changing/disabling active keywords, you must run hg kwshrink to avoid storing ex-
panded keywords in the change history.
To force expansion after enabling it, or a configuration change, run hg kwexpand.
Expansions spanning more than one line and incremental expansions, like CVS' $Log$, are
not supported. A keyword template map "Log = {desc}" expands to the first line of the
changeset description.
Commands

only files that are actual candidates for expansion.
See hg help keyword on how to construct patterns both for inclusion and exclusion of
files.
With -A/--all and -v/--verbose the codes used to show the status of files are:
K = keyword expansion candidate
k = keyword expansion candidate (not tracked)
I = ignored
i = ignored (not tracked)
Options:
-A, --all
show keyword status flags of all files
-i, --ignore

largefiles
track large binary files
Large binary files tend to be not very compressible, not very diffable, and not at all
mergeable. Such files are not handled efficiently by Mercurial's storage format (revlog),
which is based on compressed binary deltas; storing large binary files as regular Mercu-
rial files wastes bandwidth and disk space and increases Mercurial's memory usage. The
largefiles extension addresses these problems by adding a centralized client-server layer
on top of Mercurial: largefiles live in a central store out on the network somewhere, and
you only fetch the revisions that you need when you need them.
largefiles works by maintaining a "standin file" in .hglf/ for each largefile. The
standins are small (41 bytes: an SHA-1 hash plus newline) and are tracked by Mercurial.
Largefile revisions are identified by the SHA-1 hash of their contents, which is written
to the standin. largefiles uses that revision ID to get/put largefile revisions from/to
the central store. This saves both disk space and bandwidth, since you don't need to re-
trieve all historical revisions of large files when you clone or pull.
To start a new repository or add new large binary files, just add --large to your hg add
command. For example:
$ dd if=/dev/urandom of=randomdata count=2000
$ hg add --large randomdata
$ hg commit -m "add randomdata as a largefile"
When you push a changeset that adds/modifies largefiles to a remote repository, its large-
file revisions will be uploaded along with it. Note that the remote Mercurial must also
have the largefiles extension enabled for this to work.
When you pull a changeset that affects largefiles from a remote repository, the largefiles
for the changeset will by default not be pulled down. However, when you update to such a
revision, any largefiles needed by that revision are downloaded and cached (if they have
never been downloaded before). One way to pull largefiles when pulling is thus to use
--update, which will update your working copy to the latest pulled revision (and thereby
downloading any new largefiles).
If you want to pull largefiles you don't need for update yet, then you can use pull with
the --lfrev option or the hg lfpull command.
If you know you are pulling from a non-default location and want to download all the
largefiles that correspond to the new changesets at the same time, then you can pull with
--lfrev "pulled()".
If you just want to ensure that you will have the largefiles needed to merge or rebase
with new heads that you are pulling, then you can pull with --lfrev "head(pulled())" flag
to pre-emptively download any largefiles that are new in the heads you are pulling.
Keep in mind that network access may now be required to update to changesets that you have
not previously updated to. The nature of the largefiles extension means that updating is
no longer guaranteed to be a local-only operation.
If you already have large files tracked by Mercurial without the largefiles extension, you
will need to convert your repository in order to benefit from largefiles. This is done
with the hg lfconvert command:
$ hg lfconvert --size 10 oldrepo newrepo
In repositories that already have largefiles in them, any new file over 10MB will automat-
ically be added as a largefile. To change this threshold, set largefiles.minsize in your
Mercurial config file to the minimum size in megabytes to track as a largefile, or use the
--lfsize option to the add command (also in megabytes):
[largefiles]
minsize = 2
$ hg add --lfsize 2
The largefiles.patterns config option allows you to specify a list of filename patterns
(see hg help patterns) that should always be tracked as largefiles:
[largefiles]
patterns =
*.jpg
re:.*\.(png|bmp)$
library.zip
content/audio/*
Files that match one of these patterns will be added as largefiles regardless of their
size.
The largefiles.minsize and largefiles.patterns config options will be ignored for any
repositories not already containing a largefile. To add the first largefile to a reposi-
tory, you must explicitly do so with the --large flag passed to the hg add command.
Commands

lfconvert
convert a normal repository to a largefiles repository:
hg lfconvert SOURCE DEST [FILE ...]
Convert repository SOURCE to a new repository DEST, identical to SOURCE except that cer-
tain files will be converted as largefiles: specifically, any file that matches any PAT-
TERN or whose size is above the minimum size threshold is converted as a largefile. The
size used to determine whether or not to track a file as a largefile is the size of the
first version of the file. The minimum size can be specified either with --size or in con-
figuration as largefiles.size.
After running this command you will need to make sure that largefiles is enabled anywhere
you intend to push the new repository.
Use --to-normal to convert largefiles back to normal files; after this, the DEST reposi-
tory can be used without largefiles at all.
Options:
-s,--size <SIZE>
minimum size (MB) for files to be converted as largefiles
--to-normal
convert from a largefiles repo to a normal repo
lfpull
pull largefiles for the specified revisions from the specified source:
hg lfpull -r REV... [-e CMD] [--remotecmd CMD] [SOURCE]
Pull largefiles that are referenced from local changesets but missing locally, pulling
from a remote repository to the local cache.
If SOURCE is omitted, the 'default' path will be used. See hg help urls for more informa-
tion.
Some examples:
o pull largefiles for all branch heads:
hg lfpull -r "head() and not closed()"
o pull largefiles on the default branch:
hg lfpull -r "branch(default)"
Options:
-r,--rev <VALUE[+]>
pull largefiles for these revisions
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
[+] marked option can be specified multiple times
lfs
lfs - large file support (EXPERIMENTAL)
This extension allows large files to be tracked outside of the normal repository storage
and stored on a centralized server, similar to the largefiles extension. The git-lfs pro-
tocol is used when communicating with the server, so existing git infrastructure can be
harnessed. Even though the files are stored outside of the repository, they are still in-
tegrity checked in the same manner as normal files.
The files stored outside of the repository are downloaded on demand, which reduces the
time to clone, and possibly the local disk usage. This changes fundamental workflows in a
DVCS, so careful thought should be given before deploying it. hg convert can be used to
convert LFS repositories to normal repositories that no longer require this extension, and
do so without changing the commit hashes. This allows the extension to be disabled if the
centralized workflow becomes burdensome. However, the pre and post convert clones will
not be able to communicate with each other unless the extension is enabled on both.
To start a new repository, or to add LFS files to an existing one, just create an .hglfs
file as described below in the root directory of the repository. Typically, this file
should be put under version control, so that the settings will propagate to other reposi-
tories with push and pull. During any commit, Mercurial will consult this file to deter-
mine if an added or modified file should be stored externally. The type of storage de-
pends on the characteristics of the file at each commit. A file that is near a size
threshold may switch back and forth between LFS and normal storage, as needed.
Alternately, both normal repositories and largefile controlled repositories can be con-
verted to LFS by using hg convert and the lfs.track config option described below. The
.hglfs file should then be created and added, to control subsequent LFS selection. The
hashes are also unchanged in this case. The LFS and non-LFS repositories can be distin-
guished because the LFS repository will abort any command if this extension is disabled.
Committed LFS files are held locally, until the repository is pushed. Prior to pushing
the normal repository data, the LFS files that are tracked by the outgoing commits are au-
tomatically uploaded to the configured central server. No LFS files are transferred on hg
pull or hg clone. Instead, the files are downloaded on demand as they need to be read, if
a cached copy cannot be found locally. Both committing and downloading an LFS file will
link the file to a usercache, to speed up future access. See the usercache config setting
described below.
The extension reads its configuration from a versioned .hglfs configuration file found in
the root of the working directory. The .hglfs file uses the same syntax as all other Mer-
curial configuration files. It uses a single section, [track].
The [track] section specifies which files are stored as LFS (or not). Each line is keyed
by a file pattern, with a predicate value. The first file pattern match is used, so put
more specific patterns first. The available predicates are all(), none(), and size(). See
"hg help filesets.size" for the latter.
Example versioned .hglfs file:
[track]
# No Makefile or python file, anywhere, will be LFS
**Makefile = none()
**.py = none()
**.zip = all()
**.exe = size(">1MB")
# Catchall for everything not matched above
** = size(">10MB")
Configs:
[lfs]
# Remote endpoint. Multiple protocols are supported:
# - http(s)://user:pass AT example.com/path
# git-lfs endpoint
# - file:///tmp/path
# local filesystem, usually for testing
# if unset, lfs will assume the remote repository also handles blob storage
# for http(s) URLs. Otherwise, lfs will prompt to set this when it must
# use this value.
# (default: unset)
url = https://example.com/repo.git/info/lfs
# Which files to track in LFS. Path tests are "**.extname" for file
# extensions, and "path:under/some/directory" for path prefix. Both
# are relative to the repository root.
# File size can be tested with the "size()" fileset, and tests can be
# joined with fileset operators. (See "hg help filesets.operators".)
#
# Some examples:
# - all() # everything
# - none() # nothing
# - size(">20MB") # larger than 20MB
# - !**.txt # anything not a *.txt file
# - **.zip | **.tar.gz | **.7z # some types of compressed files
# - path:bin # files under "bin" in the project root
# - (**.php & size(">2MB")) | (**.js & size(">5MB")) | **.tar.gz
# | (path:bin & !path:/bin/README) | size(">1GB")
# (default: none())
#
# This is ignored if there is a tracked '.hglfs' file, and this setting
# will eventually be deprecated and removed.
track = size(">10M")
# how many times to retry before giving up on transferring an object
retry = 5
# the local directory to store lfs files for sharing across local clones.
# If not set, the cache is located in an OS specific cache location.

logtoprocess
send ui.log() data to a subprocess (EXPERIMENTAL)
This extension lets you specify a shell command per ui.log() event, sending all remaining
arguments to as environment variables to that command.
Positional arguments construct a log message, which is passed in the MSG1 environment
variables. Each keyword argument is set as a OPT_UPPERCASE_KEY variable (so the key is up-
percased, and prefixed with OPT_). The original event name is passed in the EVENT environ-
ment variable, and the process ID of mercurial is given in HGPID.
So given a call ui.log('foo', 'bar %s ', 'baz', spam='eggs'), a script configured for the
`foo event can expect an environment with MSG1=bar baz, and OPT_SPAM=eggs.
Scripts are configured in the [logtoprocess] section, each key an event name. For exam-
ple:
[logtoprocess]
commandexception = echo "$MSG1" > /var/log/mercurial_exceptions.log
would log the warning message and traceback of any failed command dispatch.
Scripts are run asynchronously as detached daemon processes; mercurial will not ensure
that they exit cleanly.
mq
manage a stack of patches
This extension lets you work with a stack of patches in a Mercurial repository. It manages
two stacks of patches - all known patches, and applied patches (subset of known patches).
Known patches are represented as patch files in the .hg/patches directory. Applied patches
are both patch files and changesets.
Common tasks (use hg help COMMAND for more details):
create new patch qnew
import existing patch qimport
print patch series qseries
print applied patches qapplied
add known patch to applied stack qpush
remove patch from applied stack qpop
refresh contents of top applied patch qrefresh
By default, mq will automatically use git patches when required to avoid losing file mode
changes, copy records, binary files or empty files creations or deletions. This behavior
can be configured with:
[mq]
git = auto/keep/yes/no
If set to 'keep', mq will obey the [diff] section configuration while preserving existing
git patches upon qrefresh. If set to 'yes' or 'no', mq will override the [diff] section
and always generate git or regular patches, possibly losing data in the second case.
It may be desirable for mq changesets to be kept in the secret phase (see hg help phases),
which can be enabled with the following setting:
[mq]
secret = True
You will by default be managing a patch queue named "patches". You can create other, inde-
pendent patch queues with the hg qqueue command.
If the working directory contains uncommitted files, qpush, qpop and qgoto abort immedi-
ately. If -f/--force is used, the changes are discarded. Setting:
[mq]
keepchanges = True
make them behave as if --keep-changes were passed, and non-conflicting local changes will
be tolerated and preserved. If incompatible options such as -f/--force or --exact are
passed, this setting is ignored.
This extension used to provide a strip command. This command now lives in the strip exten-
sion.
Commands
Repository creation
qclone
clone main and patch repository at same time:
hg qclone [OPTION]... SOURCE [DEST]
If source is local, destination will have no patches applied. If source is remote, this
command can not check if patches are applied in source, so cannot guarantee that patches
are not applied in destination. If you clone remote repository, be sure before that it has
no patches applied.
Source patch repository is looked for in <src>/.hg/patches by default. Use -p <url> to
change.
The patch directory must be a nested Mercurial repository, as would be created by hg init
--mq.
Return 0 on success.
Options:
--pull use pull protocol to copy metadata
-U, --noupdate
do not update the new working directories
--uncompressed
use uncompressed transfer (fast over LAN)
-p,--patches <REPO>
location of source patch repository
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
qinit
init a new queue repository (DEPRECATED):
hg qinit [-c]
The queue repository is unversioned by default. If -c/--create-repo is specified, qinit
will create a separate nested repository for patches (qinit -c may also be run later to
convert an unversioned patch repository into a versioned one). You can use qcommit to com-
mit changes to this queue repository.
This command is deprecated. Without -c, it's implied by other relevant commands. With -c,
use hg init --mq instead.
Options:
-c, --create-repo
create queue repository
Change creation
qcommit
commit changes in the queue repository (DEPRECATED):
hg qcommit [OPTION]... [FILE]...
This command is deprecated; use hg commit --mq instead.
Options:
-A, --addremove
mark new/missing files as added/removed before committing
--close-branch
mark a branch head as closed
--amend
amend the parent of the working directory
-s, --secret

record the specified date as commit date
-u,--user <USER>
record the specified user as committer
-S, --subrepos
recurse into subrepositories
[+] marked option can be specified multiple times
aliases: qci
qnew
create a new patch:
hg qnew [-e] [-m TEXT] [-l FILE] PATCH [FILE]...
qnew creates a new patch on top of the currently-applied patch (if any). The patch will be
initialized with any outstanding changes in the working directory. You may also use
-I/--include, -X/--exclude, and/or a list of files after the patch name to add only
changes to matching files to the new patch, leaving the rest as uncommitted modifications.
-u/--user and -d/--date can be used to set the (given) user and date, respectively.
-U/--currentuser and -D/--currentdate set user to current user and date to current date.
-e/--edit, -m/--message or -l/--logfile set the patch header as well as the commit mes-
sage. If none is specified, the header is empty and the commit message is '[mq]: PATCH'.
Use the -g/--git option to keep the patch in the git extended diff format. Read the diffs
help topic for more information on why this is important for preserving permission changes
and copy/rename information.
Returns 0 on successful creation of a new patch.
Options:
-e, --edit
invoke editor on commit messages
-f, --force
import uncommitted changes (DEPRECATED)
-g, --git
use git extended diff format
-U, --currentuser
add "From: <current user>" to patch

-l,--logfile <FILE>
read commit message from file
[+] marked option can be specified multiple times
qrefresh
update the current patch:
hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...
If any file patterns are provided, the refreshed patch will contain only the modifications
that match those patterns; the remaining modifications will remain in the working direc-
tory.
If -s/--short is specified, files currently included in the patch will be refreshed just
like matched files and remain in the patch.
If -e/--edit is specified, Mercurial will start your configured editor for you to enter a
message. In case qrefresh fails, you will find a backup of your message in .hg/last-mes-
sage.txt.
hg add/remove/copy/rename work as usual, though you might want to use git-style patches
(-g/--git or [diff] git=1) to track copies and renames. See the diffs help topic for more
information on the git diff format.
Returns 0 on success.
Options:
-e, --edit
invoke editor on commit messages
-g, --git
use git extended diff format
-s, --short
refresh only files already in the patch and specified files
-U, --currentuser
add/update author field in patch with current user
-u,--user <USER>
add/update author field in patch with given user
-D, --currentdate
add/update date field in patch with current date

[+] marked option can be specified multiple times
Change manipulation
qfold
fold the named patches into the current patch:
hg qfold [-e] [-k] [-m TEXT] [-l FILE] PATCH...
Patches must not yet be applied. Each patch will be successively applied to the current
patch in the order given. If all the patches apply successfully, the current patch will be
refreshed with the new cumulative patch, and the folded patches will be deleted. With
-k/--keep, the folded patch files will not be removed afterwards.
The header for each folded patch will be concatenated with the current patch header, sepa-
rated by a line of * * *.
Returns 0 on success.
Options:
-e, --edit
invoke editor on commit messages
-k, --keep
keep folded patch files
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
Change organization
qapplied
print the patches already applied:
hg qapplied [-1] [-s] [PATCH]
Returns 0 on success.
Options:
-1, --last
show only the preceding applied patch
-s, --summary
print first line of patch header
qdelete
remove patches from queue:
hg qdelete [-k] [PATCH]...
The patches must not be applied, and at least one patch is required. Exact patch identi-
fiers must be given. With -k/--keep, the patch files are preserved in the patch directory.
To stop managing a patch and move it into permanent history, use the hg qfinish command.
Options:
-k, --keep
keep patch file
-r,--rev <REV[+]>
stop managing a revision (DEPRECATED)
[+] marked option can be specified multiple times
aliases: qremove qrm
qfinish
move applied patches into repository history:
hg qfinish [-a] [REV]...
Finishes the specified revisions (corresponding to applied patches) by moving them out of
mq control into regular repository history.
Accepts a revision range or the -a/--applied option. If --applied is specified, all ap-
plied mq revisions are removed from mq control. Otherwise, the given revisions must be at
the base of the stack of applied patches.
This can be especially useful if your changes have been applied to an upstream repository,
or if you are about to push your changes to upstream.
Returns 0 on success.
Options:
-a, --applied
finish all applied changesets
qgoto
push or pop patches until named patch is at top of stack:
hg qgoto [OPTION]... PATCH
Returns 0 on success.
Options:
--keep-changes
tolerate non-conflicting local changes
-f, --force
overwrite any local changes
--no-backup
do not save backup copies of files
qguard
set or print guards for a patch:
hg qguard [-l] [-n] [PATCH] [-- [+GUARD]... [-GUARD]...]
Guards control whether a patch can be pushed. A patch with no guards is always pushed. A
patch with a positive guard ("+foo") is pushed only if the hg qselect command has acti-
vated it. A patch with a negative guard ("-foo") is never pushed if the hg qselect command
has activated it.
With no arguments, print the currently active guards. With arguments, set guards for the
named patch.
Note Specifying negative guards now requires '--'.
To set guards on another patch:
hg qguard other.patch -- +2.6.17 -stable
Returns 0 on success.
Options:
-l, --list
list all patches and guards
-n, --none
drop all guards
qheader
print the header of the topmost or specified patch:
hg qheader [PATCH]
Returns 0 on success.
qnext
print the name of the next pushable patch:
hg qnext [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qpop
pop the current patch off the stack:
hg qpop [-a] [-f] [PATCH | INDEX]
Without argument, pops off the top of the patch stack. If given a patch name, keeps pop-
ping off patches until the named patch is at the top of the stack.
By default, abort if the working directory contains uncommitted changes. With
--keep-changes, abort only if the uncommitted files overlap with patched files. With
-f/--force, backup and discard changes made to such files.
Return 0 on success.
Options:
-a, --all
pop all patches
-n,--name <NAME>
queue name to pop (DEPRECATED)
--keep-changes
tolerate non-conflicting local changes
-f, --force
forget any local changes to patched files
--no-backup
do not save backup copies of files
qprev
print the name of the preceding applied patch:
hg qprev [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qpush
push the next patch onto the stack:
hg qpush [-f] [-l] [-a] [--move] [PATCH | INDEX]
By default, abort if the working directory contains uncommitted changes. With
--keep-changes, abort only if the uncommitted files overlap with patched files. With
-f/--force, backup and patch over uncommitted changes.
Return 0 on success.
Options:
--keep-changes
tolerate non-conflicting local changes
-f, --force
apply on top of local changes
-e, --exact
apply the target patch to its recorded parent
-l, --list
list patch name in commit text
-a, --all
apply all patches
-m, --merge
merge from another queue (DEPRECATED)
-n,--name <NAME>
merge queue name (DEPRECATED)
--move reorder patch series and apply only the patch
--no-backup
do not save backup copies of files
qqueue
manage multiple patch queues:
hg qqueue [OPTION] [QUEUE]
Supports switching between different patch queues, as well as creating new patch queues
and deleting existing ones.
Omitting a queue name or specifying -l/--list will show you the registered queues - by de-
fault the "normal" patches queue is registered. The currently active queue will be marked
with "(active)". Specifying --active will print only the name of the active queue.
To create a new queue, use -c/--create. The queue is automatically made active, except in
the case where there are applied patches from the currently active queue in the reposi-
tory. Then the queue will only be created and switching will fail.
To delete an existing queue, use --delete. You cannot delete the currently active queue.
Returns 0 on success.
Options:
-l, --list
list all available queues
--active
print name of active queue
-c, --create
create new queue
--rename
rename active queue
--delete
delete reference to queue
--purge
delete queue, and remove patch dir
qrename
rename a patch:
hg qrename PATCH1 [PATCH2]
With one argument, renames the current patch to PATCH1. With two arguments, renames
PATCH1 to PATCH2.
Returns 0 on success.
aliases: qmv
qrestore
restore the queue state saved by a revision (DEPRECATED):
hg qrestore [-d] [-u] REV
This command is deprecated, use hg rebase instead.
Options:
-d, --delete
delete save entry
-u, --update
update queue working directory
qsave
save current queue state (DEPRECATED):
hg qsave [-m TEXT] [-l FILE] [-c] [-n NAME] [-e] [-f]
This command is deprecated, use hg rebase instead.
Options:
-c, --copy
copy patch directory
-n,--name <NAME>
copy directory name
-e, --empty
clear queue status file
-f, --force
force copy
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
qselect
set or print guarded patches to push:
hg qselect [OPTION]... [GUARD]...
Use the hg qguard command to set or print guards on patch, then use qselect to tell mq
which guards to use. A patch will be pushed if it has no guards or any positive guards
match the currently selected guard, but will not be pushed if any negative guards match
the current guard. For example:
qguard foo.patch -- -stable (negative guard)
qguard bar.patch +stable (positive guard)
qselect stable
This activates the "stable" guard. mq will skip foo.patch (because it has a negative
match) but push bar.patch (because it has a positive match).
With no arguments, prints the currently active guards. With one argument, sets the active
guard.
Use -n/--none to deactivate guards (no other arguments needed). When no guards are ac-
tive, patches with positive guards are skipped and patches with negative guards are
pushed.
qselect can change the guards on applied patches. It does not pop guarded patches by de-
fault. Use --pop to pop back to the last applied patch that is not guarded. Use --reapply
(which implies --pop) to push back to the current patch afterwards, but skip guarded
patches.
Use -s/--series to print a list of all guards in the series file (no other arguments
needed). Use -v for more information.
Returns 0 on success.
Options:
-n, --none
disable all guards
-s, --series
list all guards in series file
--pop pop to before first guarded applied patch
--reapply
pop, then reapply patches
qseries
print the entire series file:
hg qseries [-ms]
Returns 0 on success.
Options:
-m, --missing
print patches not in series
-s, --summary
print first line of patch header
qtop
print the name of the current patch:
hg qtop [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qunapplied
print the patches not yet applied:
hg qunapplied [-1] [-s] [PATCH]
Returns 0 on success.
Options:
-1, --first
show only the first patch
-s, --summary
print first line of patch header
File content management
qdiff
diff of the current patch and subsequent modifications:
hg qdiff [OPTION]... [FILE]...
Shows a diff which includes the current patch as well as any changes which have been made
in the working directory since the last refresh (thus showing what the current patch would
become after a qrefresh).
Use hg diff if you only want to see the changes made since the last qrefresh, or hg export
qtip if you want to see changes made by the current patch without including changes made
since the qrefresh.
Returns 0 on success.
Options:
-a, --text
treat all files as text
-g, --git
use git extended diff format (DEFAULT: diff.git)
--binary
generate binary diffs in git mode (default)
--nodates
omit dates from diff headers
--noprefix
omit a/ and b/ prefixes from filenames
-p, --show-function
show which function each change is in (DEFAULT: diff.showfunc)
--reverse
produce a diff that undoes the changes
-w, --ignore-all-space
ignore white space when comparing lines
-b, --ignore-space-change
ignore changes in the amount of white space
-B, --ignore-blank-lines
ignore changes whose lines are all blank
-Z, --ignore-space-at-eol
ignore changes in whitespace at EOL
-U,--unified <NUM>

--stat output diffstat-style summary of changes
--root <DIR>
produce diffs relative to subdirectory
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>

[+] marked option can be specified multiple times
Change import/export
qimport
import a patch or existing changeset:
hg qimport [-e] [-n NAME] [-f] [-g] [-P] [-r REV]... [FILE]...
The patch is inserted into the series after the last applied patch. If no patches have
been applied, qimport prepends the patch to the series.
The patch will have the same name as its source file unless you give it a new one with
-n/--name.
You can register an existing patch inside the patch directory with the -e/--existing flag.
With -f/--force, an existing patch of the same name will be overwritten.
An existing changeset may be placed under mq control with -r/--rev (e.g. qimport --rev .
-n patch will place the current revision under mq control). With -g/--git, patches im-
ported with --rev will use the git diff format. See the diffs help topic for information
on why this is important for preserving rename/copy information and permission changes.
Use hg qfinish to remove changesets from mq control.
To import a patch from standard input, pass - as the patch file. When importing from
standard input, a patch name must be specified using the --name flag.
To import an existing patch while renaming it:
hg qimport -e existing-patch -n new-name
Returns 0 if import succeeded.
Options:
-e, --existing
import file in patch directory
-n,--name <NAME>
name of patch file
-f, --force
overwrite existing files
-r,--rev <REV[+]>
place existing revisions under mq control
-g, --git
use git extended diff format
-P, --push
qpush after importing
[+] marked option can be specified multiple times
narrow
create clones which fetch history data for subset of files (EXPERIMENTAL)
Commands
Repository maintenance
tracked
show or change the current narrowspec:
hg tracked [OPTIONS]... [REMOTE]
With no argument, shows the current narrowspec entries, one per line. Each line will be
prefixed with 'I' or 'X' for included or excluded patterns, respectively.
The narrowspec is comprised of expressions to match remote files and/or directories that
should be pulled into your client. The narrowspec has include and exclude expressions,
with excludes always trumping includes: that is, if a file matches an exclude expression,
it will be excluded even if it also matches an include expression. Excluding files that
were never included has no effect.
Each included or excluded entry is in the format described by 'hg help patterns'.
The options allow you to add or remove included and excluded expressions.
If --clear is specified, then all previous includes and excludes are DROPPED and replaced
by the new ones specified to --addinclude and --addexclude. If --clear is specified with-
out any further options, the narrowspec will be empty and will not match any files.
If --auto-remove-includes is specified, then those includes that don't match any files
modified by currently visible local commits (those not shared by the remote) will be added
to the set of explicitly specified includes to remove.
--import-rules accepts a path to a file containing rules, allowing you to add --addin-
clude, --addexclude rules in bulk. Like the other include and exclude switches, the
changes are applied immediately.
Options:
--addinclude <VALUE[+]>
new paths to include
--removeinclude <VALUE[+]>
old paths to no longer include
--auto-remove-includes
automatically choose unused includes to remove
--addexclude <VALUE[+]>
new paths to exclude
--import-rules <VALUE>

notify
hooks for sending email push notifications
This extension implements hooks to send email notifications when changesets are sent from
or received by the local repository.
First, enable the extension as explained in hg help extensions, and register the hook you
want to run. incoming and changegroup hooks are run when changesets are received, while
outgoing hooks are for changesets sent to another repository:
[hooks]
# one email for each incoming changeset
incoming.notify = python:hgext.notify.hook
# one email for all incoming changesets
changegroup.notify = python:hgext.notify.hook
# one email for all outgoing changesets
outgoing.notify = python:hgext.notify.hook
This registers the hooks. To enable notification, subscribers must be assigned to reposi-
tories. The [usersubs] section maps multiple repositories to a given recipient. The [repo-
subs] section maps multiple recipients to a single repository:
[usersubs]
# key is subscriber email, value is a comma-separated list of repo patterns
user@host = pattern
[reposubs]
# key is repo pattern, value is a comma-separated list of subscriber emails
pattern = user@host
A pattern is a glob matching the absolute path to a repository, optionally combined with a
revset expression. A revset expression, if present, is separated from the glob by a hash.
Example:
[reposubs]
*/widgets#branch(release) = qa-team AT example.com
This sends to qa-team AT example.com whenever a changeset on the release branch triggers a
notification in any repository ending in widgets.
In order to place them under direct user management, [usersubs] and [reposubs] sections
may be placed in a separate hgrc file and incorporated by reference:
[notify]
config = /path/to/subscriptionsfile
Notifications will not be sent until the notify.test value is set to False; see below.
Notifications content can be tweaked with the following configuration entries:
notify.test
If True, print messages to stdout instead of sending them. Default: True.
notify.sources
Space-separated list of change sources. Notifications are activated only when a
changeset's source is in this list. Sources may be:
serve
changesets received via http or ssh
pull
changesets received via hg pull
unbundle
changesets received via hg unbundle
push
changesets sent or received via hg push
bundle
changesets sent via hg unbundle
Default: serve.
notify.strip
Number of leading slashes to strip from url paths. By default, notifications refer-
ence repositories with their absolute path. notify.strip lets you turn them into
relative paths. For example, notify.strip=3 will change /long/path/repository into
repository. Default: 0.
notify.domain
Default email domain for sender or recipients with no explicit domain. It is also
used for the domain part of the Message-Id when using notify.messageidseed.
notify.messageidseed
Create deterministic Message-Id headers for the mails based on the seed and the re-
vision identifier of the first commit in the changeset.
notify.style
Style file to use when formatting emails.
notify.template
Template to use when formatting emails.
notify.incoming
Template to use when run as an incoming hook, overriding notify.template.
notify.outgoing
Template to use when run as an outgoing hook, overriding notify.template.
notify.changegroup
Template to use when running as a changegroup hook, overriding notify.template.
notify.maxdiff
Maximum number of diff lines to include in notification email. Set to 0 to disable
the diff, or -1 to include all of it. Default: 300.
notify.maxdiffstat
Maximum number of diffstat lines to include in notification email. Set to -1 to in-
clude all of it. Default: -1.
notify.maxsubject
Maximum number of characters in email's subject line. Default: 67.
notify.diffstat
Set to True to include a diffstat before diff content. Default: True.
notify.showfunc
If set, override diff.showfunc for the diff content. Default: None.
notify.merge
If True, send notifications for merge changesets. Default: True.
notify.mbox
If set, append mails to this mbox file instead of sending. Default: None.
notify.fromauthor
If set, use the committer of the first changeset in a changegroup for the "From"
field of the notification mail. If not set, take the user from the pushing repo.
Default: False.
notify.reply-to-predecessor (EXPERIMENTAL)
If set and the changeset has a predecessor in the repository, try to thread the no-
tification mail with the predecessor. This adds the "In-Reply-To" header to the no-
tification mail with a reference to the predecessor with the smallest revision num-
ber. Mail threads can still be torn, especially when changesets are folded.
This option must be used in combination with notify.messageidseed.
If set, the following entries will also be used to customize the notifications:
email.from
Email From address to use if none can be found in the generated email content.
web.baseurl
Root repository URL to combine with repository paths when making references. See
also notify.strip.
pager
browse command output with an external pager (DEPRECATED)
Forcibly enable paging for individual commands that don't typically request pagination
with the attend-<command> option. This setting takes precedence over ignore options and
defaults:
[pager]
attend-cat = false
patchbomb
command to send changesets as (a series of) patch emails
The series is started off with a "[PATCH 0 of N]" introduction, which describes the series
as a whole.
Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the
changeset description as the subject text. The message contains two or three body parts:
o The changeset description.
o [Optional] The result of running diffstat on the patch.
o The patch itself, as generated by hg export.
Each message refers to the first in the series using the In-Reply-To and References head-
ers, so they will show up as a sequence in threaded mail and news readers, and in mail ar-
chives.
To configure other defaults, add a section like this to your configuration file:
[email]
from = My Name <my@email>
to = recipient1, recipient2, ...
cc = cc1, cc2, ...
bcc = bcc1, bcc2, ...
reply-to = address1, address2, ...
Use [patchbomb] as configuration section name if you need to override global [email] ad-
dress settings.
Then you can use the hg email command to mail a series of changesets as a patchbomb.
You can also either configure the method option in the email section to be a sendmail com-
patible mailer or fill out the [smtp] section so that the patchbomb extension can automat-
ically send patchbombs directly from the commandline. See the [email] and [smtp] sections
in hgrc(5) for details.
By default, hg email will prompt for a To or CC header if you do not supply one via con-
figuration or the command line. You can override this to never prompt by configuring an
empty value:
[email]
cc =
You can control the default inclusion of an introduction message with the patchbomb.intro
configuration option. The configuration is always overwritten by command line flags like
--intro and --desc:
[patchbomb]
intro=auto # include introduction message if more than 1 patch (default)
intro=never # never include an introduction message
intro=always # always include an introduction message
You can specify a template for flags to be added in subject prefixes. Flags specified by
--flag option are exported as {flags} keyword:
[patchbomb]
flagtemplate = "{separate(' ',
ifeq(branch, 'default', '', branch|upper),
flags)}"
You can set patchbomb to always ask for confirmation by setting patchbomb.confirm to true.
Commands
Change import/export
email
send changesets by email:
hg email [OPTION]... [DEST]...
By default, diffs are sent in the format generated by hg export, one per message. The se-
ries starts with a "[PATCH 0 of N]" introduction, which describes the series as a whole.
Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the
changeset description as the subject text. The message contains two or three parts.
First, the changeset description.
With the -d/--diffstat option, if the diffstat program is installed, the result of running
diffstat on the patch is inserted.
Finally, the patch itself, as generated by hg export.
With the -d/--diffstat or --confirm options, you will be presented with a final summary of
all messages and asked for confirmation before the messages are sent.
By default the patch is included as text in the email body for easy reviewing. Using the
-a/--attach option will instead create an attachment for the patch. With -i/--inline an
inline attachment will be created. You can include a patch both as text in the email body
and as a regular or an inline attachment by combining the -a/--attach or -i/--inline with
the --body option.
With -B/--bookmark changesets reachable by the given bookmark are selected.
With -o/--outgoing, emails will be generated for patches not found in the destination
repository (or only those which are ancestors of the specified revisions if any are pro-
vided)
With -b/--bundle, changesets are selected as for --outgoing, but a single email containing
a binary Mercurial bundle as an attachment will be sent. Use the patchbomb.bundletype con-
fig option to control the bundle type as with hg bundle --type.
With -m/--mbox, instead of previewing each patchbomb message in a pager or sending the
messages directly, it will create a UNIX mailbox file with the patch emails. This mailbox
file can be previewed with any mail user agent which supports UNIX mbox files.
With -n/--test, all steps will run, but mail will not be sent. You will be prompted for
an email recipient address, a subject and an introductory message describing the patches
of your patchbomb. Then when all is done, patchbomb messages are displayed.
In case email sending fails, you will find a backup of your series introductory message in
.hg/last-email.txt.
The default behavior of this command can be customized through configuration. (See hg help
patchbomb for details)
Examples:
hg email -r 3000 # send patch 3000 only
hg email -r 3000 -r 3001 # send patches 3000 and 3001
hg email -r 3000:3005 # send patches 3000 through 3005
hg email 3000 # send patch 3000 (deprecated)
hg email -o # send all patches not in default
hg email -o DEST # send all patches not in DEST
hg email -o -r 3000 # send all ancestors of 3000 not in default
hg email -o -r 3000 DEST # send all ancestors of 3000 not in DEST
hg email -B feature # send all ancestors of feature bookmark
hg email -b # send bundle of all patches not in default
hg email -b DEST # send bundle of all patches not in DEST
hg email -b -r 3000 # bundle of all ancestors of 3000 not in default
hg email -b -r 3000 DEST # bundle of all ancestors of 3000 not in DEST
hg email -o -m mbox && # generate an mbox file...
mutt -R -f mbox # ... and view it with mutt
hg email -o -m mbox && # generate an mbox file ...
formail -s sendmail \ # ... and use formail to send from the mbox
-bm -t < mbox # ... using sendmail
Before using this command, you will need to enable email in your hgrc. See the [email]
section in hgrc(5) for details.

phabricator
simple Phabricator integration (EXPERIMENTAL)
This extension provides a phabsend command which sends a stack of changesets to Phabrica-
tor, and a phabread command which prints a stack of revisions in a format suitable for hg
import, and a phabupdate command to update statuses in batch.
A "phabstatus" view for hg show is also provided; it displays status information of
Phabricator differentials associated with unfinished changesets.
By default, Phabricator requires Test Plan which might prevent some changeset from being
sent. The requirement could be disabled by changing differential.require-test-plan-field
config server side.
Config:
[phabricator]
# Phabricator URL
url = https://phab.example.com/
# Repo callsign. If a repo has a URL https://$HOST/diffusion/FOO, then its
# callsign is "FOO".
callsign = FOO
# curl command to use. If not set (default), use builtin HTTP library to
# communicate. If set, use the specified curl command. This could be useful
# if you need to specify advanced options that is not easily supported by
# the internal library.
curlcmd = curl --connect-timeout 2 --retry 3 --silent
# retry failed command N time (default 0). Useful when using the extension
# over flakly connection.
#
# We wait `retry.interval` between each retry, in seconds.
# (default 1 second).
retry = 3
retry.interval = 10
# the retry option can combine well with the http.timeout one.
#
# For example to give up on http request after 20 seconds:
[http]
timeout=20
[auth]
example.schemes = https
example.prefix = phab.example.com
# API token. Get it from https://$HOST/conduit/login/
example.phabtoken = cli-xxxxxxxxxxxxxxxxxxxxxxxxxxxx
Commands
Change import/export
phabimport
import patches from Phabricator for the specified Differential Revisions:
hg phabimport DREVSPEC... [OPTIONS]
The patches are read and applied starting at the parent of the working directory.
See hg help phabread for how to specify DREVSPEC.
Options:
--stack
import dependencies as well
--test-vcr <VALUE>
Path to a vcr file. If nonexistent, will record a new vcr transcript, otherwise
will mock all http requests using the specified vcr file. (ADVANCED)
phabread
print patches from Phabricator suitable for importing:
hg phabread DREVSPEC... [OPTIONS]
DREVSPEC could be a Differential Revision identity, like D123, or just the number 123. It
could also have common operators like +, -, &, (, ) for complex queries. Prefix : could be
used to select a stack. If multiple DREVSPEC values are given, the result is the union of
each individually evaluated value. No attempt is currently made to reorder the values to
run from parent to child.
abandoned, accepted, closed, needsreview, needsrevision could be used to filter patches by
status. For performance reason, they only represent a subset of non-status selections and
cannot be used alone.
For example, :D6+8-(2+D4) selects a stack up to D6, plus D8 and exclude D2 and D4. :D9 &
needsreview selects "Needs Review" revisions in a stack up to D9.
If --stack is given, follow dependencies information and read all patches. It is equiva-
lent to the : operator.
Options:
--stack
read dependencies
--test-vcr <VALUE>
Path to a vcr file. If nonexistent, will record a new vcr transcript, otherwise
will mock all http requests using the specified vcr file. (ADVANCED)
phabsend
upload changesets to Phabricator:
hg phabsend REV [OPTIONS]
If there are multiple revisions specified, they will be send as a stack with a linear de-
pendencies relationship using the order specified by the revset.
For the first time uploading changesets, local tags will be created to maintain the asso-
ciation. After the first time, phabsend will check obsstore and tags information so it can
figure out whether to update an existing Differential Revision, or create a new one.
If --amend is set, update commit messages so they have the Differential Revision URL, re-
move related tags. This is similar to what arcanist will do, and is more desired in au-
thor-push workflows. Otherwise, use local tags to record the Differential Revision associ-
ation.
The --confirm option lets you confirm changesets before sending them. You can also add
following to your configuration file to make it default behaviour:
[phabsend]
confirm = true
By default, a separate review will be created for each commit that is selected, and will
have the same parent/child relationship in Phabricator. If --fold is set, multiple com-
mits are rolled up into a single review as if diffed from the parent of the first revision
to the last. The commit messages are concatenated in the summary field on Phabricator.
phabsend will check obsstore and the above association to decide whether to update an ex-
isting Differential Revision, or create a new one.
Options:
-r,--rev <REV[+]>
revisions to send
--amend
update commit messages (default: True)
--reviewer <VALUE[+]>
specify reviewers
--blocker <VALUE[+]>
specify blocking reviewers
-m,--comment <VALUE>
add a comment to Revisions with new/updated Diffs
--confirm
ask for confirmation before sending
--fold combine the revisions into one review
--test-vcr <VALUE>
Path to a vcr file. If nonexistent, will record a new vcr transcript, otherwise
will mock all http requests using the specified vcr file. (ADVANCED)
[+] marked option can be specified multiple times
phabupdate
update Differential Revision in batch:
hg phabupdate [DREVSPEC...| -r REV...] [OPTIONS]
DREVSPEC selects revisions. See hg help phabread for its usage.
Options:
--accept
accept revisions
--reject
reject revisions
--request-review
request review on revisions
--abandon
abandon revisions
--reclaim
reclaim revisions
--close
close revisions
--reopen
reopen revisions
--plan-changes
plan changes for revisions
--resign
resign as a reviewer from revisions
--commandeer
commandeer revisions
-m,--comment <VALUE>
comment on the last revision
-r,--rev <REV>
local revision to update
--test-vcr <VALUE>
Path to a vcr file. If nonexistent, will record a new vcr transcript, otherwise
will mock all http requests using the specified vcr file. (ADVANCED)
Uncategorized commands
purge
command to delete untracked files from the working directory (DEPRECATED)
The functionality of this extension has been included in core Mercurial since version 5.7.
Please use hg purge ... instead. hg purge --confirm is now the default, unless the exten-
sion is enabled for backward compatibility.
rebase
command to move sets of revisions to a different ancestor
This extension lets you rebase changesets in an existing Mercurial repository.
For more information: https://mercurial-scm.org/wiki/RebaseExtension
Commands
Change manipulation
rebase
move changeset (and descendants) to a different branch:
hg rebase [[-s REV]... | [-b REV]... | [-r REV]...] [-d REV] [OPTION]...
Rebase uses repeated merging to graft changesets from one part of history (the source)
onto another (the destination). This can be useful for linearizing local changes relative
to a master development tree.
Published commits cannot be rebased (see hg help phases). To copy commits, see hg help
graft.
If you don't specify a destination changeset (-d/--dest), rebase will use the same logic
as hg merge to pick a destination. if the current branch contains exactly one other head,
the other head is merged with by default. Otherwise, an explicit revision with which to
merge with must be provided. (destination changeset is not modified by rebasing, but new
changesets are added as its descendants.)
Here are the ways to select changesets:
1. Explicitly select them using --rev.
2. Use --source to select a root changeset and include all of its descendants.
3. Use --base to select a changeset; rebase will find ancestors and their descendants
which are not also ancestors of the destination.
4. If you do not specify any of --rev, --source, or --base, rebase will use --base . as
above.
If --source or --rev is used, special names SRC and ALLSRC can be used in --dest. Destina-
tion would be calculated per source revision with SRC substituted by that single source
revision and ALLSRC substituted by all source revisions.
Rebase will destroy original changesets unless you use --keep. It will also move your
bookmarks (even if you do).
Some changesets may be dropped if they do not contribute changes (e.g. merges from the
destination branch).
Unlike merge, rebase will do nothing if you are at the branch tip of a named branch with
two heads. You will need to explicitly specify source and/or destination.
If you need to use a tool to automate merge/conflict decisions, you can specify one with
--tool, see hg help merge-tools. As a caveat: the tool will not be used to mediate when a
file was deleted, there is no hook presently available for this.
If a rebase is interrupted to manually resolve a conflict, it can be continued with --con-
tinue/-c, aborted with --abort/-a, or stopped with --stop.
Examples:
o move "local changes" (current commit back to branching point) to the current branch tip
after a pull:
hg rebase
o move a single changeset to the stable branch:
hg rebase -r 5f493448 -d stable
o splice a commit and all its descendants onto another part of history:
hg rebase --source c0c3 --dest 4cf9
o rebase everything on a branch marked by a bookmark onto the default branch:
hg rebase --base myfeature --dest default
o collapse a sequence of changes into a single commit:
hg rebase --collapse -r 1520:1525 -d .
o move a named branch while preserving its name:
hg rebase -r "branch(featureX)" -d 1.3 --keepbranches
o stabilize orphaned changesets so history looks linear:
hg rebase -r 'orphan()-obsolete()' -d 'first(max((successors(max(roots(ALLSRC) & ::SRC)^)-obsolete())::) + max(::((roots(ALLSRC) & ::SRC)^)-obsolete()))'
Configuration Options:
You can make rebase require a destination if you set the following config option:
[commands]
rebase.requiredest = True
By default, rebase will close the transaction after each commit. For performance purposes,
you can configure rebase to use a single transaction across the entire rebase. WARNING:
This setting introduces a significant risk of losing the work you've done in a rebase if
the rebase aborts unexpectedly:
[rebase]
singletransaction = True
By default, rebase writes to the working copy, but you can configure it to run in-memory
for better performance. When the rebase is not moving the parent(s) of the working copy
(AKA the "currently checked out changesets"), this may also allow it to run even if the
working copy is dirty:
[rebase]
experimental.inmemory = True
Return Values:
Returns 0 on success, 1 if nothing to rebase or there are unresolved conflicts.

commands to interactively select changes for commit/qrefresh (DEPRECATED)
The feature provided by this extension has been moved into core Mercurial as hg commit
--interactive.
Commands
Change creation
qrecord
interactively record a new patch:
hg qrecord [OPTION]... PATCH [FILE]...
See hg help qnew & hg help record for more information and usage.

[+] marked option can be specified multiple times
releasenotes
generate release notes from commit messages (EXPERIMENTAL)
It is common to maintain files detailing changes in a project between releases. Maintain-
ing these files can be difficult and time consuming. The hg releasenotes command provided
by this extension makes the process simpler by automating it.
Commands
Change navigation
releasenotes
parse release notes from commit messages into an output file:
hg releasenotes [-r REV] [-c] FILE
Given an output file and set of revisions, this command will parse commit messages for re-
lease notes then add them to the output file.
Release notes are defined in commit messages as ReStructuredText directives. These have
the form:
.. directive:: title
content
Each directive maps to an output section in a generated release notes file, which itself
is ReStructuredText. For example, the .. feature:: directive would map to a New Features
section.
Release note directives can be either short-form or long-form. In short- form, title is
omitted and the release note is rendered as a bullet list. In long form, a sub-section
with the title title is added to the section.
The FILE argument controls the output file to write gathered release notes to. The format
of the file is:
Section 1
=========
...
Section 2
=========
...
Only sections with defined release notes are emitted.
If a section only has short-form notes, it will consist of bullet list:
Section
=======
* Release note 1
* Release note 2
If a section has long-form notes, sub-sections will be emitted:
Section
=======
Note 1 Title
------------
Description of the first long-form note.
Note 2 Title
------------
Description of the second long-form note.
If the FILE argument points to an existing file, that file will be parsed for release
notes having the format that would be generated by this command. The notes from the pro-
cessed commit messages will be merged into this parsed set.
During release notes merging:
o Duplicate items are automatically ignored
o Items that are different are automatically ignored if the similarity is greater than a
threshold.
This means that the release notes file can be updated independently from this command and
changes should not be lost when running this command on that file. A particular use case
for this is to tweak the wording of a release note after it has been added to the release
notes file.
The -c/--check option checks the commit message for invalid admonitions.
The -l/--list option, presents the user with a list of existing available admonitions
along with their title. This also includes the custom admonitions (if any).
Options:

relink
recreates hardlinks between repository clones
Commands
Repository maintenance
relink
recreate hardlinks between two repositories:
hg relink [ORIGIN]
When repositories are cloned locally, their data files will be hardlinked so that they
only use the space of a single repository.
Unfortunately, subsequent pulls into either repository will break hardlinks for any files
touched by the new changesets, even if both repositories end up pulling the same changes.
Similarly, passing --rev to "hg clone" will fail to use any hardlinks, falling back to a
complete copy of the source repository.
This command lets you recreate those hardlinks and reclaim that wasted space.
This repository will be relinked to share space with ORIGIN, which must be on the same lo-
cal disk. If ORIGIN is omitted, looks for "default-relink", then "default", in [paths].
Do not attempt any read operations on this repository while the command is running. (Both
repositories will be locked against writes.)
remotefilelog
remotefilelog causes Mercurial to lazilly fetch file contents (EXPERIMENTAL)
This extension is HIGHLY EXPERIMENTAL. There are NO BACKWARDS COMPATIBILITY GUARANTEES.
This means that repositories created with this extension may only be usable with the exact
version of this extension/Mercurial that was used. The extension attempts to enforce this
in order to prevent repository corruption.
remotefilelog works by fetching file contents lazily and storing them in a cache on the
client rather than in revlogs. This allows enormous histories to be transferred only par-
tially, making them easier to operate on.
Configs:
packs.maxchainlen specifies the maximum delta chain length in pack files
packs.maxpacksize specifies the maximum pack file size
packs.maxpackfilecount specifies the maximum number of packs in the
shared cache (trees only for now)
remotefilelog.backgroundprefetch runs prefetch in background when True
remotefilelog.bgprefetchrevs specifies revisions to fetch on commit and
update, and on other commands that use them. Different from pullprefetch.
remotefilelog.gcrepack does garbage collection during repack when True
remotefilelog.nodettl specifies maximum TTL of a node in seconds before
it is garbage collected
remotefilelog.repackonhggc runs repack on hg gc when True
remotefilelog.prefetchdays specifies the maximum age of a commit in
days after which it is no longer prefetched.
remotefilelog.prefetchdelay specifies delay between background
prefetches in seconds after operations that change the working copy parent
remotefilelog.data.gencountlimit constraints the minimum number of data
pack files required to be considered part of a generation. In particular, mini-
mum number of packs files > gencountlimit.
remotefilelog.data.generations list for specifying the lower bound of
each generation of the data pack files. For example, list ['100MB','1MB'] or
['1MB', '100MB'] will lead to three generations: [0, 1MB), [ 1MB, 100MB) and
[100MB, infinity).
remotefilelog.data.maxrepackpacks the maximum number of pack files to
include in an incremental data repack.
remotefilelog.data.repackmaxpacksize the maximum size of a pack file for
it to be considered for an incremental data repack.
remotefilelog.data.repacksizelimit the maximum total size of pack files
to include in an incremental data repack.
remotefilelog.history.gencountlimit constraints the minimum number of
history pack files required to be considered part of a generation. In particu-
lar, minimum number of packs files > gencountlimit.
remotefilelog.history.generations list for specifying the lower bound of
each generation of the history pack files. For example, list [ '100MB', '1MB']
or ['1MB', '100MB'] will lead to three generations: [ 0, 1MB), [1MB, 100MB) and
[100MB, infinity).
remotefilelog.history.maxrepackpacks the maximum number of pack files to
include in an incremental history repack.
remotefilelog.history.repackmaxpacksize the maximum size of a pack file
for it to be considered for an incremental history repack.
remotefilelog.history.repacksizelimit the maximum total size of pack
files to include in an incremental history repack.
remotefilelog.backgroundrepack automatically consolidate packs in the
background
remotefilelog.cachepath path to cache
remotefilelog.cachegroup if set, make cache directory sgid to this
group
remotefilelog.cacheprocess binary to invoke for fetching file data
remotefilelog.debug turn on remotefilelog-specific debug output
remotefilelog.excludepattern pattern of files to exclude from pulls
remotefilelog.includepattern pattern of files to include in pulls
remotefilelog.fetchwarning: message to print when too many
single-file fetches occur
remotefilelog.getfilesstep number of files to request in a single RPC
remotefilelog.getfilestype if set to 'threaded' use threads to fetch
files, otherwise use optimistic fetching
remotefilelog.pullprefetch revset for selecting files that should be
eagerly downloaded rather than lazily
remotefilelog.reponame name of the repo. If set, used to partition
data from other repos in a shared store.
remotefilelog.server if true, enable server-side functionality
remotefilelog.servercachepath path for caching blobs on the server
remotefilelog.serverexpiration number of days to keep cached server
blobs
remotefilelog.validatecache if set, check cache entries for corruption
before returning blobs
remotefilelog.validatecachelog if set, check cache entries for
corruption before returning metadata
Commands
Repository maintenance
prefetch
prefetch file revisions from the server:
hg prefetch [OPTIONS] [FILE...]
Prefetchs file revisions for the specified revs and stores them in the local remotefilelog
cache. If no rev is specified, the default rev is used which is the union of dot, draft,
pullprefetch and bgprefetchrev. File names or patterns can be used to limit which files
are downloaded.
Return 0 on success.
Options:
-r,--rev <REV[+]>
prefetch the specified revisions
--repack
run repack after prefetch
-b,--base <VALUE>
rev that is assumed to already be local
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
Uncategorized commands
gc
garbage collect the client and server filelog caches:
hg gc [REPO...]
garbage collect the client and server filelog caches
repack
hg repack [OPTIONS]
Options:
--background
run in a background process
--incremental
do an incremental repack
--packsonly
only repack packs (skip loose objects)
verifyremotefilelog
hg verifyremotefilelogs <directory>
Options:
-d, --decompress

remotenames
showing remotebookmarks and remotebranches in UI (EXPERIMENTAL)
By default both remotebookmarks and remotebranches are turned on. Config knob to control
the individually are as follows.
Config options to tweak the default behaviour:
remotenames.bookmarks
Boolean value to enable or disable showing of remotebookmarks (default: True)
remotenames.branches
Boolean value to enable or disable showing of remotebranches (default: True)
remotenames.hoistedpeer
Name of the peer whose remotebookmarks should be hoisted into the top-level name-
space (default: 'default')
schemes
extend schemes with shortcuts to repository swarms
This extension allows you to specify shortcuts for parent URLs with a lot of repositories
to act like a scheme, for example:
[schemes]
py = http://code.python.org/hg/
After that you can use it like:
hg clone py://trunk/
Additionally there is support for some more complex schemas, for example used by Google
Code:
[schemes]
gcode = http://{1}.googlecode.com/hg/
The syntax is taken from Mercurial templates, and you have unlimited number of variables,
starting with {1} and continuing with {2}, {3} and so on. This variables will receive
parts of URL supplied, split by /. Anything not specified as {part} will be just appended
to an URL.
For convenience, the extension adds these schemes by default:
[schemes]
py = http://hg.python.org/
bb = https://bitbucket.org/
bb+ssh = ssh://hg AT bitbucket.org/
gcode = https://{1}.googlecode.com/hg/
kiln = https://{1}.kilnhg.com/Repo/
You can override a predefined scheme by defining a new scheme with the same name.
Commands
Uncategorized commands
share
share a common history between several working directories
The share extension introduces a new command hg share to create a new working directory.
This is similar to hg clone, but doesn't involve copying or linking the storage of the
repository. This allows working on different branches or changes in parallel without the
associated cost in terms of disk space.
Note: destructive operations or extensions like hg rollback should be used with care as
they can result in confusing problems.
Automatic Pooled Storage for Clones
When this extension is active, hg clone can be configured to automatically share/pool
storage across multiple clones. This mode effectively converts hg clone to hg clone + hg
share. The benefit of using this mode is the automatic management of store paths and in-
telligent pooling of related repositories.
The following share. config options influence this feature:
share.pool
Filesystem path where shared repository data will be stored. When defined, hg clone
will automatically use shared repository storage instead of creating a store inside
each clone.
share.poolnaming
How directory names in share.pool are constructed.
"identity" means the name is derived from the first changeset in the repository. In
this mode, different remotes share storage if their root/initial changeset is iden-
tical. In this mode, the local shared repository is an aggregate of all encountered
remote repositories.
"remote" means the name is derived from the source repository's path or URL. In
this mode, storage is only shared if the path or URL requested in the hg clone com-
mand matches exactly to a repository that was cloned before.
The default naming mode is "identity".
Sharing requirements and configs of source repository with shares:
By default creating a shared repository only enables sharing a common history and does not
share requirements and configs between them. This may lead to problems in some cases, for
example when you upgrade the storage format from one repository but does not set related
configs in the shares.
Setting format.exp-share-safe = True enables sharing configs and requirements. This only
applies to shares which are done after enabling the config option.
For enabling this in existing shares, enable the config option and reshare.
For resharing existing shares, make sure your working directory is clean and there are no
untracked files, delete that share and create a new share.
Commands
Repository creation
share
create a new shared repository:
hg share [-U] [-B] SOURCE [DEST]
Initialize a new repository and working directory that shares its history (and optionally
bookmarks) with another repository.
Note using rollback or extensions that destroy/modify history (mq, rebase, etc.) can
cause considerable confusion with shared clones. In particular, if two shared
clones are both updated to the same changeset, and one of them destroys that
changeset with rollback, the other clone will suddenly stop working: all operations
will fail with "abort: working directory has unknown parent". The only known work-
around is to use debugsetparents on the broken clone to reset it to a changeset
that still exists.
Options:
-U, --noupdate
do not create a working directory
-B, --bookmarks
also share bookmarks
--relative
point to source using a relative path
Repository maintenance
unshare
convert a shared repository to a normal one:
hg unshare
Copy the store data to the repo and remove the sharedpath data.
show
unified command to show various repository information (EXPERIMENTAL)
This extension provides the hg show command, which provides a central command for display-
ing commonly-accessed repository data and views of that data.
The following config options can influence operation.
commands
show.aliasprefix
List of strings that will register aliases for views. e.g. s will effectively set
config options alias.s<view> = show <view> for all views. i.e. hg swork would exe-
cute hg show work.
Aliases that would conflict with existing registrations will not be performed.
Commands
Change navigation
show
show various repository information:
hg show VIEW
A requested view of repository data is displayed.
If no view is requested, the list of available views is shown and the command aborts.
Note There are no backwards compatibility guarantees for the output of this command.
Output may change in any future Mercurial release.
Consumers wanting stable command output should specify a template via -T/--tem-
plate.
List of available views:
bookmarks bookmarks and their associated changeset
stack current line of work
work changesets that aren't finished
Options:
-T,--template <TEMPLATE>
display with template
sparse
allow sparse checkouts of the working directory (EXPERIMENTAL)
(This extension is not yet protected by backwards compatibility guarantees. Any aspect may
break in future releases until this notice is removed.)
This extension allows the working directory to only consist of a subset of files for the
revision. This allows specific files or directories to be explicitly included or excluded.
Many repository operations have performance proportional to the number of files in the
working directory. So only realizing a subset of files in the working directory can im-
prove performance.
Sparse Config Files
The set of files that are part of a sparse checkout are defined by a sparse config file.
The file defines 3 things: includes (files to include in the sparse checkout), excludes
(files to exclude from the sparse checkout), and profiles (links to other config files).
The file format is newline delimited. Empty lines and lines beginning with # are ignored.
Lines beginning with %include `` denote another sparse config file to include. e.g. ``%in-
clude tests.sparse. The filename is relative to the repository root.
The special lines [include] and [exclude] denote the section for includes and excludes
that follow, respectively. It is illegal to have [include] after [exclude].
Non-special lines resemble file patterns to be added to either includes or excludes. The
syntax of these lines is documented by hg help patterns. Patterns are interpreted as
glob: by default and match against the root of the repository.
Exclusion patterns take precedence over inclusion patterns. So even if a file is explic-
itly included, an [exclude] entry can remove it.
For example, say you have a repository with 3 directories, frontend/, backend/, and
tools/. frontend/ and backend/ correspond to different projects and it is uncommon for
someone working on one to need the files for the other. But tools/ contains files shared
between both projects. Your sparse config files may resemble:
# frontend.sparse
frontend/**
tools/**
# backend.sparse
backend/**
tools/**
Say the backend grows in size. Or there's a directory with thousands of files you wish to
exclude. You can modify the profile to exclude certain files:
[include]
backend/**
tools/**
[exclude]
tools/tests/**
Commands
Uncategorized commands
split
command to split a changeset into smaller ones (EXPERIMENTAL)
Commands
Change manipulation
split
split a changeset into smaller ones:
hg split [--no-rebase] [[-r] REV]
Repeatedly prompt changes and commit message for new changesets until there is nothing
left in the original changeset.
If --rev was not given, split the working directory parent.
By default, rebase connected non-obsoleted descendants onto the new changeset. Use
--no-rebase to avoid the rebase.
Options:
-r,--rev <REV>
revision to split
--rebase
rebase descendants after split (default: True)
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
sqlitestore
store repository data in SQLite (EXPERIMENTAL)
The sqlitestore extension enables the storage of repository data in SQLite.
This extension is HIGHLY EXPERIMENTAL. There are NO BACKWARDS COMPATIBILITY GUARANTEES.
This means that repositories created with this extension may only be usable with the exact
version of this extension/Mercurial that was used. The extension attempts to enforce this
in order to prevent repository corruption.
In addition, several features are not yet supported or have known bugs:
o Only some data is stored in SQLite. Changeset, manifest, and other repository data is
not yet stored in SQLite.
o Transactions are not robust. If the process is aborted at the right time during transac-
tion close/rollback, the repository could be in an inconsistent state. This problem will
diminish once all repository data is tracked by SQLite.
o Bundle repositories do not work (the ability to use e.g. hg -R <bundle-file> log to au-
tomatically overlay a bundle on top of the existing repository).
o Various other features don't work.
This extension should work for basic clone/pull, update, and commit workflows. Some his-
tory rewriting operations may fail due to lack of support for bundle repositories.
To use, activate the extension and set the storage.new-repo-backend config option to
sqlite to enable new repositories to use SQLite for storage.
strip
strip changesets and their descendants from history (DEPRECATED)
The functionality of this extension has been included in core Mercurial since version 5.7.
Please use hg debugstrip ... instead.
This extension allows you to strip changesets and all their descendants from the reposi-
tory. See the command help for details.
transplant
command to transplant changesets from another branch
This extension allows you to transplant changes to another parent revision, possibly in
another repository. The transplant is done using 'diff' patches.
Transplanted patches are recorded in .hg/transplant/transplants, as a map from a changeset
hash to its hash in the source repository.
Commands
Change manipulation
transplant
transplant changesets from another branch:
hg transplant [-s REPO] [-b BRANCH [-a]] [-p REV] [-m REV] [REV]...
Selected changesets will be applied on top of the current working directory with the log
of the original changeset. The changesets are copied and will thus appear twice in the
history with different identities.
Consider using the graft command if everything is inside the same repository - it will use
merges and will usually give a better result. Use the rebase extension if the changesets
are unpublished and you want to move them instead of copying them.
If --log is specified, log messages will have a comment appended of the form:
(transplanted from CHANGESETHASH)
You can rewrite the changelog message with the --filter option. Its argument will be in-
voked with the current changelog message as $1 and the patch as $2.
--source/-s specifies another repository to use for selecting changesets, just as if it
temporarily had been pulled. If --branch/-b is specified, these revisions will be used as
heads when deciding which changesets to transplant, just as if only these revisions had
been pulled. If --all/-a is specified, all the revisions up to the heads specified with
--branch will be transplanted.
Example:
o transplant all changes up to REV on top of your current revision:
hg transplant --branch REV --all
You can optionally mark selected transplanted changesets as merge changesets. You will not
be prompted to transplant any ancestors of a merged transplant, and you can merge descen-
dants of them normally instead of transplanting them.
Merge changesets may be transplanted directly by specifying the proper parent changeset by
calling hg transplant --parent.
If no merges or revisions are provided, hg transplant will start an interactive changeset
browser.
If a changeset application fails, you can fix the merge by hand and then resume where you
left off by calling hg transplant --continue/-c.
Options:
-s,--source <REPO>
transplant changesets from REPO
-b,--branch <REV[+]>
use this source changeset as head
-a, --all
pull all changesets up to the --branch revisions
-p,--prune <REV[+]>
skip over REV
-m,--merge <REV[+]>
merge at REV
--parent <REV>
parent to choose when transplanting merge
-e, --edit
invoke editor on commit messages
--log append transplant info to log message
--stop stop interrupted transplant
-c, --continue
continue last transplant session after fixing conflicts
--filter <CMD>
filter changesets through command
[+] marked option can be specified multiple times
uncommit
uncommit part or all of a local changeset (EXPERIMENTAL)
This command undoes the effect of a local commit, returning the affected files to their
uncommitted state. This means that files modified, added or removed in the changeset will
be left unchanged, and so will remain modified, added and removed in the working direc-
tory.
Commands
Change manipulation
unamend
undo the most recent amend operation on a current changeset:
hg unamend
This command will roll back to the previous version of a changeset, leaving working direc-
tory in state in which it was before running hg amend (e.g. files modified as part of an
amend will be marked as modified hg status)
uncommit
uncommit part or all of a local changeset:
hg uncommit [OPTION]... [FILE]...
This command undoes the effect of a local commit, returning the affected files to their
uncommitted state. This means that files modified or deleted in the changeset will be left
unchanged, and so will remain modified in the working directory.
If no files are specified, the commit will be pruned, unless --keep is given.
Options:
--keep allow an empty commit after uncommitting
--allow-dirty-working-copy
allow uncommit with outstanding changes
-n,--note <TEXT>
store a note on uncommit
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
-D, --currentdate
record the current date as commit date
-U, --currentuser
record the current user as committer
[+] marked option can be specified multiple times
win32mbcs
allow the use of MBCS paths with problematic encodings
Some MBCS encodings are not good for some path operations (i.e. splitting path, case con-
version, etc.) with its encoded bytes. We call such a encoding (i.e. shift_jis and big5)
as "problematic encoding". This extension can be used to fix the issue with those encod-
ings by wrapping some functions to convert to Unicode string before path operation.
This extension is useful for:
o Japanese Windows users using shift_jis encoding.
o Chinese Windows users using big5 encoding.
o All users who use a repository with one of problematic encodings on case-insensitive
file system.
This extension is not needed for:
o Any user who use only ASCII chars in path.
o Any user who do not use any of problematic encodings.
Note that there are some limitations on using this extension:
o You should use single encoding in one repository.
o If the repository path ends with 0x5c, .hg/hgrc cannot be read.
o win32mbcs is not compatible with fixutf8 extension.
By default, win32mbcs uses encoding.encoding decided by Mercurial. You can specify the
encoding by config option:
[win32mbcs]
encoding = sjis
It is useful for the users who want to commit with UTF-8 log message.
win32text
perform automatic newline conversion (DEPRECATED)
Deprecation: The win32text extension requires each user to configure the extension
again and again for each clone since the configuration is not copied when cloning.
We have therefore made the eol as an alternative. The eol uses a version controlled
file for its configuration and each clone will therefore use the right settings from
the start.
To perform automatic newline conversion, use:
[extensions]
win32text =
[encode]
** = cleverencode:
# or ** = macencode:
[decode]
** = cleverdecode:
# or ** = macdecode:
If not doing conversion, to make sure you do not commit CRLF/CR by accident:
[hooks]
pretxncommit.crlf = python:hgext.win32text.forbidcrlf
# or pretxncommit.cr = python:hgext.win32text.forbidcr
To do the same check on a server to prevent CRLF/CR from being pushed or pulled:
[hooks]
pretxnchangegroup.crlf = python:hgext.win32text.forbidcrlf
# or pretxnchangegroup.cr = python:hgext.win32text.forbidcr
zeroconf
discover and advertise repositories on the local network
The zeroconf extension will advertise hg serve instances over DNS-SD so that they can be
discovered using the hg paths command without knowing the server's IP address.
To allow other people to discover your repository using run hg serve in your repository:
$ cd test
$ hg serve
You can discover Zeroconf-enabled repositories by running hg paths:
$ hg paths
zc-test = http://example.com:8000/test
FILES
/etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc
This file contains defaults and configuration. Values in .hg/hgrc override those in
$HOME/.hgrc, and these override settings made in the global /etc/mercurial/hgrc
configuration. See hgrc(5) for details of the contents and format of these files.
.hgignore
This file contains regular expressions (one per line) that describe file names that
should be ignored by hg. For details, see hgignore(5).
.hgsub
This file defines the locations of all subrepositories, and tells where the sub-
repository checkouts came from. For details, see hg help subrepos.
.hgsubstate
This file is where Mercurial stores all nested repository states. NB: This file
should not be edited manually.
.hgtags
This file contains changeset hash values and text tag names (one of each separated
by spaces) that correspond to tagged versions of the repository contents. The file
content is encoded using UTF-8.
.hg/last-message.txt
This file is used by hg commit to store a backup of the commit message in case the
commit fails.
.hg/localtags
This file can be used to define local tags which are not shared among repositories.
The file format is the same as for .hgtags, but it is encoded using the local sys-
tem encoding.
Some commands (e.g. revert) produce backup files ending in .orig, if the .orig file al-
ready exists and is not tracked by Mercurial, it will be overwritten.
BUGS
Probably lots, please post them to the mailing list (see Resources below) when you find
them.
