Net::LDAP::LDIF(3pm) User Contributed Perl Documentation Net::LDAP::LDIF(3pm)
NAME
Net::LDAP::LDIF - LDIF reading and writing
SYNOPSIS
use Net::LDAP::LDIF;
$ldif = Net::LDAP::LDIF->new( "file.ldif", "r", onerror => 'undef' );
while ( not $ldif->eof ( ) ) {
$entry = $ldif->read_entry ( );
if ( $ldif->error ( ) ) {
print "Error msg: ", $ldif->error ( ), "\n";
print "Error lines:\n", $ldif->error_lines ( ), "\n";
} else {
# do stuff
}
}
$ldif->done ( );
DESCRIPTION
Net::LDAP::LDIF provides a means to convert between Net::LDAP::Entry objects and LDAP
entries represented in LDIF format files. Reading and writing are supported and may
manipulate single entries or lists of entries.
As when reading an entire file into memory with perl normally, take into account the
possibility of memory use when loading an LDIF file in one go.
SPECIAL FEATURES
By default, Net::LDAP::LDIF supports reading attribute values from URLs of type "file://".
When Gisle Aas' LWP module package is installed, Net::LDAP::LDIF uses it to also support
reading data from the URL types supported by these modules; most prominently "http://",
"https://", and "ftp://" resources. This extended feature is dynamically detected at
runtime.
CONSTRUCTOR
new ( FILE [[, MODE ], OPTIONS ] )
Open the file with the given mode.
"FILE" may be the name of a file or an already open filehandle. If "FILE" begins or
ends with a "|" then "FILE" will be passed directly to "open".
"MODE" can be any of the modes allowed for Perl's open() function, potentially
extended by PerlIO layers as described in perlopentut. Alternatively, it can be one
of the mode indicators "r", "r+", "w", "w+", "a", "a+" known from C's fopen()
function, which get mapped to their Perl counterparts. If "MODE" is omitted, it
defaults to "r" for reading.
"OPTIONS" is a list of name/value pairs, recognizing:
encode => 'none' | 'canonical' | 'base64'
Some DN values in LDIF cannot be written verbatim and have to be encoded in some
way:
'none'
The default.
'canonical'
See "canonical_dn" in Net::LDAP::Util.
'base64'
Use base64.
onerror => 'die' | 'warn' | 'undef'
Specify what happens when an error is detected.
'die'
"Net::LDAP::LDIF" will croak with an appropriate message.
'warn'
"Net::LDAP::LDIF" will warn with an appropriate message.
'undef'
"Net::LDAP::LDIF" will warn with an appropriate message if "-w" is in effect.
The method that was called will return "undef".
Note this value is the string 'undef', not the "undef" value.
change => 1
Write entry changes to the LDIF file instead of the entries itself. I.e. write
LDAP operations acting on the entries to the file instead of the entries contents.
lowercase => 1
Convert attribute names to lowercase when writing.
sort => 1
Sort attribute names when writing entries according to the rule: objectclass first
then all other attributes alphabetically sorted
version => '1'
Set the LDIF version to write to the resulting LDIF file.
According to RFC 2849 currently the only legal value for this option is 1.
When this option is set Net::LDAP::LDIF tries to adhere more strictly to the LDIF
specification in RFC2489 in a few places.
The default is undef meaning no version information is written to the LDIF file.
wrap => 78
Number of columns where output line wrapping shall occur.
Default is 78. Setting it to 40 or lower inhibits wrapping.
raw => REGEX
Use REGEX to denote the names of attributes that are to be considered binary when
reading.
When this option is given, Net::LDAP converts all values of attributes not
matching this REGEX into Perl UTF-8 strings so that the regular Perl operators
(pattern matching, ...) can operate as one expects even on strings with
international characters.
If this option is not given, attribute values are treated as byte strings.
Example: raw => qr/(?i:^jpegPhoto|;binary)/
METHODS
read_entry ( )
Read one entry from the file and return it as a "Net::LDAP::Entry" object.
In scalar mode, the "Net::LDAP::Entry" object is returned alone, while in list mode a
list is returned consisting of the "Net::LDAP::Entry" object as first element followed
by all "Net::LDAP::Control" objects that were part of the LDIF entry. See RFC 2849
for details.
eof ( )
Returns true when the end of the file is reached.
write_entry ( ENTRY [, OPTIONS ], ... )
Write entries to the LDIF file.
The arguments accepted are a list of entries, optionally interspersed with options
belonging to the preceding entry.
For each entry, "OPTIONS" is a list of key-value pairs, recognizing:
control => CONTROL
control => [ CONTROL, ... ]
See "CONTROLS" in Net::LDAP.
write_version ( )
If the object's version is defined, this method allows one to explicitly write the
version before an entry is written.
If not called explicitly, it gets called automatically when writing the first entry.
version ( [ VERSION ] )
If called without arguments it returns the version of the LDIF file or undef if no
version has been set. If called with an argument it sets the LDIF version to VERSION.
According to RFC 2849 currently the only legal value for VERSION is 1.
handle ( )
Returns the file handle the "Net::LDAP::LDIF" object reads from or writes to.
done ( )
This method signals that the LDIF object is no longer needed. If a file was opened
automatically when the object was created it will be closed. This method is called
automatically via DESTROY when the object goes out of scope.
error ( )
Returns error message if error was found.
error_lines ( )
Returns lines that resulted in error.
current_entry ( )
Returns the current "Net::LDAP::Entry" object.
current_lines ( )
Returns the lines that generated the current "Net::LDAP::Entry" object.
next_lines ( )
Returns the lines that will generate the next "Net::LDAP::Entry" object.
