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>;

# Set $entries_are_in_gettext_format if the .pl files above use
# loc('%1') instead of loc('[_1]')
$Ext->compile($entries_are_in_gettext_format);

$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.

METHODS

Constructor

Accessors

header, set_header
lexicon, set_lexicon, msgstr, set_msgstr
entries, set_entries, entry, add_entry, del_entry
compiled_entries, set_compiled_entries, compiled_entry,
add_compiled_entry, del_compiled_entry
clear

PO File manipulation

method read_po ($file)

method write_po ($file, $add_format_marker?)

Extraction

extract
extract_file

Compilation

compile($entries_are_in_gettext_style?)

Merges the entries into compiled_entries.

If $entries_are_in_gettext_style is true, the previously extracted entries are assumed to be in the Gettext style (e.g. %1).

Otherwise they are assumed to be in Maketext style (e.g. [_1]) and are converted into Gettext style before merging into compiled_entries.

The entries are not cleared after each compilation; use -set_entries()> to clear them if you need to extract from sources with varying styles.

Lexicon accessors

msgids, has_msgid,
msgstr, set_msgstr
msg_positions, msg_variables, msg_format, msg_out

Internal utilities

_default_header
_maketext_to_gettext
_escape
_format

ACKNOWLEDGMENTS

Thanks to Jesse Vincent for contributing to an early version of this module.

Also to Alain Barbet, who effectively re-wrote the source parser with a flex-like algorithm.
