=head1 NAME

Locale::PO - Perl module for manipulating .po entries from GNU gettext

=head1 SYNOPSIS

use Locale::PO;

$po = new Locale::PO([-option=>value,...])
    [$string =] $po->msgid([new string]);
    [$string =] $po->msgstr([new string]);
    [$string =] $po->comment([new string]);
    [$string =] $po->automatic([new string]);
    [$string =] $po->reference([new string]);
    [$value =] $po->fuzzy([value]);
    [$value =] $po->add_flag('c-format');
    print $po->dump;

$quoted_string = $po->quote($string);
    $string = $po->dequote($quoted_string);

$aref = Locale::PO->load_file_asarray(<filename>,[encoding]);
    $href = Locale::PO->load_file_ashash(<filename>,[encoding]);
    Locale::PO->save_file_fromarray(<filename>,$aref,[encoding]);
    Locale::PO->save_file_fromhash(<filename>,$href,[encoding]);

=head1 DESCRIPTION

This module simplifies management of GNU gettext .po files and is an
alternative to using emacs po-mode. It provides an object-oriented
interface in which each entry in a .po file is a Locale::PO object.

=head1 METHODS

=over 4

=item new

my Locale::PO $po = new Locale::PO;
    my Locale::PO $po = new Locale::PO(%options);

Create a new Locale::PO object to represent a po entry.
You can optionally set the attributes of the entry by passing
a list/hash of the form:

-option=>value, -option=>value, etc.

Where options are msgid, msgid_plural, msgstr, msgctxt, comment, automatic,
reference, fuzzy_msgctxt, fuzzy_msgid, fuzzy_msgid_plural,
fuzzy, and c-format. See accessor methods below.

To generate a po file header, add an entry with an empty
msgid, like this:

$po = new Locale::PO(-msgid=>'', -msgstr=>
	    "Project-Id-Version: PACKAGE VERSION\\n" .
	    "PO-Revision-Date: YEAR-MO-DA HO:MI +ZONE\\n" .
	    "Last-Translator: FULL NAME <EMAIL@ADDRESS>\\n" .
	    "Language-Team: LANGUAGE <LL@li.org>\\n" .
	    "MIME-Version: 1.0\\n" .
	    "Content-Type: text/plain; charset=CHARSET\\n" .
	    "Content-Transfer-Encoding: ENCODING\\n");

=item msgid

Set or get the untranslated string from the object.

This method expects the new string in unquoted form but returns the current string in quoted form.

=item msgid_plural

Set or get the untranslated plural string from the object.

This method expects the new string in unquoted form but returns the current string in quoted form.

=item msgstr

Set or get the translated string from the object.

This method expects the new string in unquoted form but returns the current string in quoted form.

=item msgstr_n

Get or set the translations if there are purals involved. Takes and
returns a hashref where the keys are the 'N' case and the values are
the strings. eg:

$po->msgstr_n(
	{
	    0 => 'found %d plural translations',
	    1 => 'found %d singular translation',
	}
    );

This method expects the new strings in unquoted form but returns the current strings in quoted form.

=item msgctxt

Set or get the translation context string from the object.

This method expects the new string in unquoted form but returns the current string in quoted form.

=item fuzzy_msgid

Set or get the outdated untranslated string from the object.

This method expects the new string in unquoted form but returns the current string in quoted form.

=item fuzzy_msgid_plural

Set or get the outdated untranslated plural string from the object.

This method expects the new string in unquoted form but returns the current string in quoted form.

=item fuzzy_msgctxt

Set or get the outdated translation context string from the object.

This method expects the new string in unquoted form but returns the current string in quoted form.

=item obsolete

Returns 1 if the entry is obsolete.
Obsolete entries have their msgid, msgid_plural, msgstr, msgstr_n and msgctxt lines commented out with "#~"

When using load_file_ashash, non-obsolete entries will always replace obsolete entries with the same msgid.

=item comment

Set or get translator comments from the object.

If there are no such comments, then the value is undef.  Otherwise,
the value is a string that contains the comment lines delimited with
"\n".  The string includes neither the S<"# "> at the beginning of
each comment line nor the newline at the end of the last comment line.

=item automatic

Set or get automatic comments from the object (inserted by
emacs po-mode or xgettext).

If there are no such comments, then the value is undef.  Otherwise,
the value is a string that contains the comment lines delimited with
"\n".  The string includes neither the S<"#. "> at the beginning of
each comment line nor the newline at the end of the last comment line.

=item reference

Set or get reference marking comments from the object (inserted
by emacs po-mode or gettext).

=item fuzzy

Set or get the fuzzy flag on the object ("check this translation").
When setting, use 1 to turn on fuzzy, and 0 to turn it off.

=item c_format

Set or get the c-format or no-c-format flag on the object.

This can take 3 values:
1 implies c-format, 0 implies no-c-format, and undefined implies neither.

=item php_format

Set or get the php-format or no-php-format flag on the object.

This can take 3 values:
1 implies php-format, 0 implies no-php-format, and undefined implies neither.

=item has_flag

if ($po->has_flag('perl-format')) {
	    ...
    }

Returns true if the flag exists in the entry's #~ comment

=item add_flag

$po->add_flag('perl-format');

Adds the flag to the #~ comment

=item remove_flag

$po->remove_flag('perl-format');

Removes the flag from the #~ comment

=item loaded_line_number

When using one of the load_file_as* methods,
this will return the line number that the entry started at in the file.

=item dump

Returns the entry as a string, suitable for output to a po file.

=item quote

Applies po quotation rules to a string, and returns the quoted
string. The quoted string will have all existing double-quote
characters escaped by backslashes, and will be enclosed in double
quotes.

=item dequote

Returns a quoted po string to its natural form.

=item load_file_asarray

Given the filename of a po-file, reads the file and returns a
reference to a list of Locale::PO objects corresponding to the contents of
the file, in the same order.  Accepts an optional encoding parameter (e.g.
"utf8") which defines how the po-file's input stream will be configured.

=item load_file_ashash

Given the filename of a po-file, reads the file and returns a
reference to a hash of Locale::PO objects corresponding to the contents of
the file. The hash keys are the untranslated strings, so this is a cheap
way to remove duplicates. The method will prefer to keep entries that
have been translated.  Accepts an optional encoding parameter (e.g.
"utf8") which defines how the po-file's input stream will be configured.

=item save_file_fromarray

Given a filename and a reference to a list of Locale::PO objects,
saves those objects to the file, creating a po-file.  Accepts an optional
encoding parameter (e.g. "utf8") which defines how the po-file's output
stream will be configured.

=item save_file_fromhash

Given a filename and a reference to a hash of Locale::PO objects,
saves those objects to the file, creating a po-file. The entries
are sorted alphabetically by untranslated string.  Accepts an optional
encoding parameter (e.g. "utf8") which defines how the po-file's output
stream will be configured.

=head1 BUGS

If you load_file_as* then save_file_from*, the output file may have slight
cosmetic differences from the input file (an extra blank line here or there).

msgid, msgid_plural, msgstr, msgstr_n and msgctxt expect a non-quoted string as input, but return quoted strings.
I'm hesitant to change this in fear of breaking the modules/scripts of people already using Locale::PO.

Locale::PO requires blank lines between entries, but Uniforum style PO
files don't have any.

Please submit all bug requests using CPAN's ticketing system.
