Locale::Maketext::Lexicon::Gettext(3)

NAME
Locale::Maketext::Lexicon::Gettext - PO and MO file parser for Maketext

SYNOPSIS
Called via Locale::Maketext::Lexicon:

    package Hello::I18N;
    use base 'Locale::Maketext';
    use Locale::Maketext::Lexicon {
        de => [Gettext => 'hello/de.mo'],
    };

Directly calling "parse()":

    use Locale::Maketext::Lexicon::Gettext;
    my %Lexicon = %{ Locale::Maketext::Lexicon::Gettext->parse(<DATA>) };
    __DATA__
    #: Hello.pm:10
    msgid "Hello, World!"
    msgstr "Hallo, Welt!"

    #: Hello.pm:11
    msgid "You have %quant(%1,piece) of mail."
    msgstr "Sie haben %quant(%1,Poststueck,Poststuecken)."

DESCRIPTION
This module implements a perl-based "Gettext" parser for Locale::Maketext. It transforms all %1, %2, <%*>... sequences to "[_1]", "[_2]", "[_*]", and so on. It accepts either plain PO file, or a MO file which will be handled with a pure-perl parser adapted from Imacat's "Locale::Maketext::Gettext".

Since version 0.03, this module also looks for "%function(args...)" in the lexicon strings, and transform it to "[function,args...]". Any %1, %2... sequences inside the args will have their percent signs ("%") replaced by underscores ("_").

The name of function above should begin with a letter or underscore, followed by any number of alphanumeric characters and/or underscores. As an exception, the function name may also consist of a single asterisk ("*") or pound sign ("#"), which are "Locale::Maketext"'s shorthands for "quant" and "numf", respectively.

As an additional feature, this module also parses MIME-header style metadata specified in the null msgstr (""), and add them to the %Lexicon with a "__" prefix. For example, the example above will set "__Content-Type" to "text/plain; charset=iso8859-1", without the newline or the colon.

Any normal entry that duplicates a metadata entry takes precedence. Hence, a "msgid "__Content-Type"" line occurs anywhere should override the above value.

OPTIONS

  use_fuzzy
When parsing PO files, fuzzy entries (entries marked with "#, fuzzy") are silently ignored. If you wish to use fuzzy entries, specify a true value to the "_use_fuzzy" option:

    use Locale::Maketext::Lexicon {
        de => [Gettext => 'hello/de.mo'],
        _use_fuzzy => 1,
    };

  allow_empty
When parsing PO files, empty entries (entries with "msgstr """) are silently ignored. If you wish to allow empty entries, specify a true value to the "_allow_empty" option:

    use Locale::Maketext::Lexicon {
        de => [Gettext => 'hello/de.mo'],
        _allow_empty => 1,
    };
