=head1 SYNOPSIS
|
|
|
|
use Locale::Po4a::Po;
|
|
my $pofile=Locale::Po4a::Po->new();
|
|
|
|
# Read PO file
|

|
|
|
|
# Add an entry
|
|
$pofile->push('msgid' => 'Hello', 'msgstr' => 'bonjour',
|
|
'flags' => "wrap", 'reference'=>'file.c:46');
|
|
|
|
# Extract a translation
|

=head1 DESCRIPTION
|
|
|
|
Locale::Po4a::Po is a module that allows you to manipulate message
|
|
catalogs. You can load and write from/to a file (which extension is often
|
|
I<po>), you can build new entries on the fly or request for the translation
|
|
of a string.
|
|
|
|
For a more complete description of message catalogs in the PO format and
|
|
their use, please refer to the documentation of the gettext program.
|
|
|
|
This module is part of the po4a project, which objective is to use PO files
|
|
(designed at origin to ease the translation of program messages) to
|
|
translate everything, including documentation (man page, info manual),
|
|
package description, debconf templates, and everything which may benefit
|
|
from this.

=head1 OPTIONS ACCEPTED BY THIS MODULE
|
|
|
|
=over 4
|
|
|
|
=item B<porefs> I<type>[,B<wrap>|B<nowrap>]
|
|
|
|
Specify the reference format. Argument I<type> can be one of B<none> to not
|
|
produce any reference, B<noline> to not specify the line number (more
|
|
accurately all line numbers are replaced by 1), B<counter> to replace line
|
|
number by an increasing counter, and B<full> to include complete
|
|
references.
|
|
|
|
Argument can be followed by a comma and either B<wrap> or B<nowrap> keyword.
|
|
References are written by default on a single line. The B<wrap> option wraps
|
|
references on several lines, to mimic B<gettext> tools (B<xgettext> and
|
|
B<msgmerge>). This option will become the default in a future release, because
|
|
it is more sensible. The B<nowrap> option is available so that users who want
|
|
to keep the old behavior can do so.
|
|
|
|
=item B<--msgid-bugs-address> I<email@address>
|
|
|
|
Set the report address for msgid bugs. By default, the created POT files
|
|
have no Report-Msgid-Bugs-To fields.
|
|
|
|
=item B<--copyright-holder> I<string>
|
|
|
|
Set the copyright holder in the POT header. The default value is
|
|
"Free Software Foundation, Inc."
|
|
|
|
=item B<--package-name> I<string>
|
|
|
|
Set the package name for the POT header. The default is "PACKAGE".
|
|
|
|
=item B<--package-version> I<string>
|
|
|
|
Set the package version for the POT header. The default is "VERSION".

=item push(%)
|
|
|
|
Push a new entry at the end of the current catalog. The arguments should
|
|
form a hash table. The valid keys are:
|
|
|
|
=over 4
|
|
|
|
=item B<msgid>
|
|
|
|
the string in original language.
|
|
|
|
=item B<msgstr>
|
|
|
|
the translation.
|
|
|
|
=item B<reference>
|
|
|
|
an indication of where this string was found. Example: file.c:46 (meaning
|
|
in 'file.c' at line 46). It can be a space-separated list in case of
|
|
multiple occurrences.
|
|
|
|
=item B<comment>
|
|
|
|
a comment added here manually (by the translators). The format here is free.
|
|
|
|
=item B<automatic>
|
|
|
|
a comment which was automatically added by the string extraction
|
|
program. See the B<--add-comments> option of the B<xgettext> program for
|
|
more information.
|
|
|
|
=item B<flags>
|
|
|
|
space-separated list of all defined flags for this entry.
|
|
|
|
Valid flags are: B<c-text>, B<python-text>, B<lisp-text>, B<elisp-text>, B<librep-text>,
|
|
B<smalltalk-text>, B<java-text>, B<awk-text>, B<object-pascal-text>, B<ycp-text>,
|
|
B<tcl-text>, B<wrap>, B<no-wrap> and B<fuzzy>.
|
|
|
|
See the gettext documentation for their meaning.
|
|
|
|
=item B<type>
|
|
|
|
this is mostly an internal argument: it is used while gettextizing
|
|
documents. The idea here is to parse both the original and the translation
|
|
into a PO object, and merge them, using one's msgid as msgid and the
|
|
other's msgid as msgstr. To make sure that things get ok, each msgid in PO
|
|
objects are given a type, based on their structure (like "chapt", "sect1",
|
|
"p" and so on in DocBook). If the types of strings are not the same, that
|
|
means that both files do not share the same structure, and the process
|
|
reports an error.
|
|
|
|
This information is written as automatic comment in the PO file since this
|
|
gives to translators some context about the strings to translate.
|
|
|
|
=item B<wrap>
|
|
|
|
boolean indicating whether whitespaces can be mangled in cosmetic
|
|
reformattings. If true, the string is canonized before use.
|
|
|
|
This information is written to the PO file using the B<wrap> or B<no-wrap> flag.
|
|
|
|
=item B<wrapcol>
|
|
|
|
the column at which we should wrap (default: 76).
|
|
|
|
This information is not written to the PO file.
