Log::Report::Lexicon::POT - manage PO files

 Log::Report::Lexicon::POT
   is a Log::Report::Lexicon::Table


 # this is usually not for end-users, See ::Extract::PerlPPI
 # using a PO table
 my $pot = Log::Report::Lexicon::POT
    ->read('po/nl.po', charset => 'utf-8')
        or die;
 my $po = $pot->msgid('msgid');
 my $po = $pot->msgid($msgid, $msgctxt);
 print $pot->nrPlurals;
 print $pot->msgstr('msgid', 3);
 print $pot->msgstr($msgid, 3, $msgctxt);
 $pot->write;  # update the file
 # fill the table, by calling the next a lot
 my $po  = Log::Report::Lexicon::PO->new(...);
 $pot->add($po);
 # creating a PO table
 $pot->write('po/nl.po')
     or die;

This module is reading, extending, and writing POT files. POT files are used to store translations in humanly readable format for most of existing translation frameworks, like GNU gettext and Perl's Maketext. If you only wish to access the translation, then you may use the much more efficient Log::Report::Lexicon::POTcompact.

The code is loosely based on Locale::PO, by Alan Schwartz. The coding style is a bit off the rest of "Log::Report", and there was a need to sincere simplification. Each PO record will be represented by a Log::Report::Lexicon::PO.

Extends "DESCRIPTION" in Log::Report::Lexicon::Table.

Extends "METHODS" in Log::Report::Lexicon::Table.

Extends "Constructors" in Log::Report::Lexicon::Table.

Create a new POT file. The initial header is generated for you, but it can be changed using the header() method. 

 -Option      --Default
  charset       'UTF-8'
  date          now
  filename      undef
  index         {}
  nr_plurals    2
  plural_alg    n!=1
  plural_forms  <constructed from nr_plurals and plural_alg>
  textdomain    <required>
  version       undef
The charset to be used for the createed file. It is unwise to use anything else than 'UTF-8', but allowed. Before [1.09] this option was required.
Overrule the date which is included in the generated header.
Specify an output filename. The name can also be specified when write() is called.
A set of translations (Log::Report::Lexicon::PO objects), with msgid as key.
The number of translations each of the translation with plural form need to have.
The algorithm to be used to calculate which translated msgstr to use.
[0.992] When this option is used, it overrules "nr_plurals" and "plural_alg". The RULE should be a full "Plural-Forms" field.
The package name, used in the directory structure to store the PO files.
Read the POT information from $filename. 

 -Option --Default
  charset  <required>
The character-set which is used for the file. You must specify this explicitly.
$obj->write( [$filename|$fh], %options )
When you pass an open $fh, you are yourself responsible that the correct character-encoding (binmode) is set. When the write followed a read() or the filename was explicitly set with filename(), then you may omit the first parameter. 

 -Option     --Default
  only_active  false
[1.02] Do not write records which do have a translation, but where the msgid has disappeared from the sources. By default, these records are commented out (marked with '#~') but left in the file.

Extends "Attributes" in Log::Report::Lexicon::Table.

$obj->charset()
The character-set to be used for reading and writing. You do not need to be aware of Perl's internal encoding for the characters.
$obj->filename()
Returns the $filename, as derived from read() or specified during initiation with new(filename).
$obj->index()
Returns a HASH of all defined PO objects, organized by msgid. Please try to avoid using this: use msgid() for lookup and add() for adding translations.
$obj->language()
Returns the language code, which is derived from the filename.

Extends "Managing PO's" in Log::Report::Lexicon::Table.

$obj->keepReferencesTo($table)
Remove all references which are not found as key in the hash $table. Returns the number of references left.
$obj->removeReferencesTo($filename)
Remove all the references to the indicate $filename from all defined translations. Returns the number of refs left.
$obj->stats()
Returns a HASH with some statistics about this POT table.
$obj->updated( [$date] )
Replace the "PO-Revision-Date" with the specified $date, or the current moment.

Translation

Extends "Translation" in Log::Report::Lexicon::Table.

$obj->msgid( STRING, [$msgctxt] )
Lookup the Log::Report::Lexicon::PO with the STRING. If you want to add a new translation, use add(). Returns "undef" when not defined.
$obj->msgstr( $msgid, [$count, [$msgctxt]] )
Returns the translated string for $msgid. When $count is not specified or "undef", the translation string related to "1" is returned.

Administration

Extends "Administration" in Log::Report::Lexicon::Table.

$obj->add($po)
Add the information from a $po into this POT. If the msgid of the $po is already known, that is an error.
$obj->header( [$field, [$content]] )
The translation of a blank MSGID is used to store a MIME header, which contains some meta-data. When only a $field is specified, that content is looked-up (case-insensitive) and returned. When a $content is specified, the knowledge will be stored. In latter case, the header structure may get created. When the $content is set to "undef", the field will be removed.
$obj->nrPlurals()
Inherited, see "Administration" in Log::Report::Lexicon::Table
$obj->pluralIndex($count)
Inherited, see "Administration" in Log::Report::Lexicon::Table
$obj->setupPluralAlgorithm()
Inherited, see "Administration" in Log::Report::Lexicon::Table
$obj->translations( [$active] )
Returns a list with all defined Log::Report::Lexicon::PO objects. When the string $active is given as parameter, only objects which have references are returned.

When a PO file is written, then a filename or file-handle must be specified explicitly, or set beforehand using the filename() method, or known because the write follows a read() of the file.
