VERSION

version 0.008

SYNOPSIS

  #in ./i18n/file.json
  {
    "en": {
      "color": {
        "trans" : "color"
        "meta": {
          "searchable": 1,
        }
      }
    },
    "en_gb": {
      "color": {
        "trans": "colour"
      }
    }
  }

  # in your app
  use Locale::Meta

  my $lm = Locale::Meta->new('./i18n');
 
        print $lm->loc('color', 'en_gb'); # prints 'colour'

DESCRIPTION

Locale::Meta has been inspired by Locale::Wolowitz, and the base code, documentation, and function has been taken from it. The main goal of Locale::Meta is to provide the same functionality as Locale::Wolowitz, but removing the dependency of the file names as part of the definition of the language, to manage a new json data structure for the .json files definitions, and also, add a meta field in order to be able to extend the use of the locate to other purposes, like search.

The objective of the package is to take different json structures, transform the data into key/value structure and build a big repository into memory to be use as base point to localize language definitions.

The metadata attribute "meta" defined on the json file is optional and is used to maintain information related to the definition of the term.

package Locale::Meta;

CONSTRUCTOR

new( [ $path / $filename, \%options ] )

Creates a new instance of this module. A path to a directory in which JSON localization files exist, or a path to a specific localization file. If you pass a directory, all JSON localization files in it will be loaded and merged. If you pass one file, only that file will be loaded.

Note that Locale::Meta will ignore dotfiles in the provided path (e.g. hidden files, backups files, etc.).

A hash-ref of options can also be provided. The only option currently supported is utf8, which is on by default. If on, all JSON files are assumed to be in UTF-8 character set and will be automatically decoded. Provide a false value if your files are not UTF-8 encoded, for example:

        Locale::Meta->new( '/path/to/files', { utf8 => 0 } );

OBJECT METHODS

load_path( $path / $filename )

Receives a path to a directory in which JSON localization files exist, or a path to a specific localization file, and loads (and merges) the localization data from the file(s). If localization data was already loaded previously, the structure will be merged, with the new data taking precedence.

You can call this method and load_structure() as much as you want, the data from each call will be merged with existing data.

charge($structure)

  Load #structure into $self->{locales}

loc( $msg, $lang, [ @args ] )

Returns the string $msg, translated to the requested language (if such a translation exists, otherwise no traslation occurs). Any other parameters passed to the method (@args) are injected to the placeholders in the string (if present).

DIAGNOSTICS

The following exceptions are thrown by this module:

"You must provide a path to localization directory."

This exception is thrown if you haven't provided the new() subroutine a path to a localization file, or a directory of localization files. Read the documentation for the new() subroutine above.

"Can't open localization directory: %s" and "Can't close localization directory: %s"

This exception is thrown if Locale::Meta failed to open/close the directory of the localization files. This will probably happen due to permission problems. The error message should include the actual reason for the failure.

"Path must be to a directory or a JSON file."

This exception is thrown if you passed a wrong value to the new() subroutine as the path to the localization directory/file. Either the path is wrong and thus does not exist, or the path does exist, but is not a directory and not a file.

"Can't open localization file %s: %s" and "Can't close localization file %s: %s"

This exception is thrown if Locale::Wolowitz fails to open/close a specific localization file. This will usually happen because of permission problems. The error message will include both the name of the file, and the actual reason for the failure.

CONFIGURATION AND ENVIRONMENT

Locale::Meta requires no configuration files or environment variables.

DEPENDENCIES

Locale::Meta depends on the following CPAN modules:

Locale::Meta recommends Cpanel::JSON::XS or JSON::XS for faster parsing of JSON files.

INCOMPATIBILITIES WITH OTHER MODULES

None reported.
