grunt-require-gettext

Grunt plugin to process js files and extract calls to gettext that is used with a requirejs gettext module.

Getting Started

This plugin requires Grunt >=0.4.0

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-require-gettext --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-require-gettext');

As a first example, this projects’s Gruntfile.js does contain some tasks, that will compile the test files from spec/ directory. Use these as a first start.

The "compile_po" task

In your project's Gruntfile, add a section named compile_po to the data object passed into grunt.initConfig().

grunt.initConfig({
  options: {
    //Task-specific options go here
  },
  compile_po: {
    options: {
      // Target-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    }
  }
});

Options

options.cacheDir

Type: string Default value: $(grunt-require-gettext path)/.cache/ (usually node_module/grunt-require-gettext/.cache)

Use cacheDir as the directory for reference cache used by compile_po task. Sometimes it's useful to write the cache files somewhere else, for more easy access from the project using grunt-require-gettext to extract strings. This directory contains pot file(s), that could be sent to translators to create the po files for each supported language.

options.cacheFile

Type: string Default value: cache.pot

Use cacheFile as the filename of the reference cache used by compile_po task. Sometimes it's useful to write the cache files somewhere else, for more easy access from the project using grunt-require-gettext to extract strings. This pot file could be sent to translators to create the po files for each supported language.

options.includeFuzzy

Type: boolean Default value: undefined

Include messages flagged as fuzzy into the catalog. Default is not to include such messages, but sometimes they should not be filtered. Use this option to include fuzzy messages.

options.template

Type: String Default value: null

A path to a template file containing an underscore/lodash compatible template. If template is empty, the default template will be used:

define("<%= module %>.<%= language %>", [], function () {
    return {
        "module": "<%= module %>",
        "language": "<%= language %>",
        "nplurals": <%= nplurals %>,
        "plural": "<%= plural %>",
        "dictionary": {
<% for (var msgid in dictionary) {%>
            "<%= msgid %>": "<%= dictionary[msgid] %>",
<% } %>
        }
    };
});

files format

Since the compile_po task will extract a module name from the reference comments of the translated string (it will be inserted there by the create_pot task), there will most likely be more modules created, than po files as sources. Therefor the destination of the files given must be a directory. The task will fail if this is not the case.

The "create_pot" task

Overview

In your project's Gruntfile, add a section named create_pot to the data object passed into grunt.initConfig().

grunt.initConfig({
  create_pot: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
});

Options

options.headers

Type: Object Default value:

{
  'Content-Type': 'text/plain; charset=UTF-8',
  'Content-Transfer-Encoding': '8bit'
}

Headers that should be added to the pot file.

options.location

Type: String Default value: 'full'

One of the standard Gettext options for --add-location: 'full', 'file' or 'none'. Full includes line numbers, file includes only file names and none omits the location entirely.

Note: module is always added and is not influenced by this option.
