NAME ^

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

INHERITANCE ^

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

SYNOPSIS ^

 # 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');
 print $pot->nrPlurals;
 print $pot->msgstr('msgid', 3);
 $pot->write;

 # creating a PO table

 my $po  = Log::Report::Lexicon::PO->new(...);
 $pot->add($po);

 $pot->write('po/nl.po')
     or die;

DESCRIPTION ^

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.

METHODS ^

Constructors

Log::Report::Lexicon::POT->new(OPTIONS)

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

 -Option      --Default
  charset       <required>
  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
charset => STRING

The character-set which is used for the output.

date => STRING

Overrule the date which is included in the generated header.

filename => STRING

Specify an output filename. The name can also be specified when write() is called.

index => HASH

A set of translations (Log::Report::Lexicon::PO objects), with msgid as key.

nr_plurals => INTEGER

The number of translations each of the translation with plural form need to have.

plural_alg => EXPRESSION

The algorithm to be used to calculate which translated msgstr to use.

plural_forms => RULE

[0.992] When this option is used, it overrules nr_plurals and plural_alg. The RULE should be a full "Plural-Forms" field.

textdomain => STRING

The package name, used in the directory structure to store the PO files.

version => STRING
Log::Report::Lexicon::POT->read(FILENAME, OPTIONS)

Read the POT information from FILENAME.

 -Option --Default
  charset  <required>
charset => STRING

The character-set which is used for the file. You must specify this explicitly, while it cannot be trustfully detected automatically.

$obj->write([FILENAME|FILEHANDLE], OPTIONS)

When you pass an open FILEHANDLE, 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.

Attributes

$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.

Managing PO's

$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

$obj->msgid(STRING)

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])

Returns the translated string for MSGID. When COUNT is not specified, the translation string related to "1" is returned.

Administration

$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()

See "Administration" in Log::Report::Lexicon::Table

$obj->pluralIndex(COUNT)

See "Administration" in Log::Report::Lexicon::Table

$obj->setupPluralAlgorithm()

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.

DIAGNOSTICS ^

Error: charset parameter is required
Error: no filename or file-handle specified for PO

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.

Error: only acceptable parameter is 'ACTIVE'
Error: textdomain parameter is required
