NAME

Locale::Maketext::Extract - Extract translatable strings from source

SYNOPSIS

    my $Ext = Locale::Maketext::Extract->new;
    $Ext->read_po('messages.po');
    $Ext->extract_file($_) for <*.pl>;
    $Ext->compile;
    $Ext->write_po('messages.po');

DESCRIPTION

This module can extract translatable strings from files, and write them back to PO files. It can also parse existing PO files and merge their contents with newly extracted strings.

A command-line utility, xgettext.pl, is installed with this module as well.

Following formats of input files are supported:

Perl source files

Valid localization function names are: translate, maketext, gettext, loc, x, _ and __.

HTML::Mason

Strings inside <&|/l>...</&> and <&|/loc>...</&> are extracted.

Template Toolkit

Strings inside [%|l%]...[%END%] or [%|loc%]...[%END%] are extracted.

Text::Template

Sentences between STARTxxx and ENDxxx are extracted individually.

Generic Template

Strings inside {{...}} are extracted.
