NAME
mhical - nmh's manipulator of iCalendar event requests
SYNOPSIS
mhical [-help] [-version] [-form formatfile] [-format formatstring] [[-reply accept | de-
cline | tentative] | -cancel] [-contenttype] [-infile infile] [-outfile outfile]
[-unfold] [-debug]
DESCRIPTION
mhical manipulates an iCalendar (.ics) event request, to display it, generate a reply to
it, or cancel it. iCalendar event requests and replies are defined by RFC 5545.
The default operation is to display the iCalendar event request in a human-readable for-
mat.
For the display operation, the -format string and -form formatfile switches may be used to
specify a format string or a format file to read. If given a format string, it must be
specified as a single argument to the -format switch. If given a format file name with
-form, the file is searched for using the normal nmh rules: absolute pathnames are ac-
cessed directly, tilde expansion is done on usernames, and files are searched for in the
user's Mail directory as specified in their profile. If not found there, the directory
"/etc/nmh" is checked. mhical defaults to using a format file named mhical.24hour, and
will use the one installed in the "/etc/nmh" directory if not found elsewhere.
The following format components are supported:
method
organizer
summary
description
location
dtstart
dtend
attendees
Those format names are case-sensitive. Each corresponds to the iCalendar property of the
same name as defined in RFC 5545, with the exception of attendees. That is a comma-delim-
ited list of the common name (CN), if available, or email address of Attendee properties.
A maximum of 20 will be displayed.
Timezone
mhical will display the event with times converted to the timezone specified by the TZ en-
vironment variable, if it is set, see tzset(3). If not set, its behavior is implementa-
tion defined, but may use the user's local timezone.
Reply
The -reply switch generates a reply from the event request. The required action parameter
must be one of accept, decline, or tentative. Delegation is not supported.
Cancel
The -cancel switch generates an iCalendar event that can be used to cancel the event re-
quest.
Input/Output
By default, mhical reads from standard input and writes to standard output. The -infile
and -outfile, respectively, switches can be used to override these defaults.
Miscellaneous Switches
The -contenttype switch instructs mhical to insert a Content-Type header at the beginning
of its output, for use by mhbuild. It can only be used with -reply and -cancel.
The -unfold switch echoes the event request, but with all lines unfolded.
The -debug switch reveals minute details of the parse process.
FILES
mhical looks for format files in multiple locations: absolute pathnames are accessed di-
rectly, tilde expansion is done on usernames, and files are searched for in the user's
Mail directory as specified in their profile. If not found there, the directory
"/etc/nmh" is checked.
/etc/nmh/mhical.24hour The default display template
/etc/nmh/mhical.12hour Display template that uses 12-hour clock
SEE ALSO
mhbuild(1), mh-format(5), tzset(3), repl(1)
DEFAULTS
`-form' defaults to mhical.24hour
`-infile' defaults to standard input
`-outfile' defaults to standard output
BUGS
mhical supports only a very limited subset of RRULE formats. Specifically, only a fre-
quency of YEARLY and an interval of 1 are supported.
