grunt-i18n-abide

Grunt plugin for running jsxgettext and gettext tools against your codebase. jsxgettext extracts strings from your JS and template files (EJS/Jinja (nunjucks)) to a pot format.

Upgrade notes

Version 0.0.20 of i18n-abide has changed how it handles locales with script subtags. E.g. sr_LATN now becomes sr_Latn. In other words locales with script subtags are now formatted so the initial character of the subtag is capitalized and the remainder is lower-case. If you’re using i18n-abide >= 0.0.20 rename any locales from xx_XXXX to xx_Xxxx. If you’re using 0.0.20 of i18n-abide you should also upgrade to grunt-i18n-abide >= 0.0.11.

Getting Started

This plugin requires Grunt ~0.4.1

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-i18n-abide --save-dev

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

grunt.loadNpmTasks('grunt-i18n-abide');

The tasks

• abideExtract
• abideCreate
• abideMerge
• abideCompile

The abideExtract task

Overview

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

This example show two targets for extracting strings from JS and HTML. They both use the same destination.

  abideExtract: {
    js: {
      src: 'lib/**/*.js',
      dest: 'locale/templates/LC_MESSAGES/messages.pot',
      options: {
        language: 'JavaScript',
      }
    },
    html: {
      src: 'templates/**/*.html',
      dest: 'locale/templates/LC_MESSAGES/messages.pot',
      options: {
        language: 'Jinja',
      }
    },
  }

Files

src

Standard grunt files src config allowing a set of paths to make up the list of files that are searched for gettext strings.

dest

Standard grunt files dest config allowing configuration of where the pot file should be created.

Default value: locale/templates/LC\_MESSAGES/messages.pot

Options

options.join

Type: Boolean Default value: true

Join messages that already exist.

options.keyword

Type: String

A way to specify what gettext function you are using e.g. ‘_’ for _(‘Translate this’)

options.language

Type: String Default value: 'JavaScript'

A string value to tell jsxgettext what type of code you are extracting strings from.

The abideCreate task

Overview

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

Options

  abideCreate: {
    default: { // Target name.
      options: {
        template: 'locale/templates/LC_MESSAGES/messages.pot', // (default: 'locale/templates/LC_MESSAGES/messages.pot')
        languages: ['en-US', 'fr', 'es'],
        localeDir: 'locale',
      }
    }
  },

Options

options.template

Type: String Default value: locale/templates/LC\_MESSAGES/messages.pot

The path to the template pot file strings are extracted to.

options.languages

Type: Array

A list of the language codes you want to create locales for e.g. en-US not en_US.

options.localeDir

Type: String Default value: locale

The base locale directory.

The abideMerge task

Overview

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

This command merges newly extracted strings into the locales.

Options

  abideMerge: {
    default: { // Target name.
      options: {
        template: 'locale/templates/LC_MESSAGES/messages.pot', // (default: 'locale/templates/LC_MESSAGES/messages.pot')
        localeDir: 'locale',
      }
    }
  },

Options

options.template

Type: String Default value: locale/templates/LC\_MESSAGES/messages.pot

The path to the template pot file strings are extracted to.

options.localeDir

Type: String Default value: locale

The base locale directory.

The abideCompile task

Overview

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

This command can take multiple targets, so you can compile more than one set of files if you want or a mix of mo/JSON.

Example Conf

  abideCompile: {
    json: {
      dest: '/json/',
      options: {
        type: 'json',
        localeDir: 'tests/tmp',
      }
    },
    mo: {
      options: {
        type: 'mo',
        localeDir: 'tests/tmp',
      }
    }
  },

Files

dest

Standard grunt files dest config allowing configuration of where the json should end up.

Options

options.type

Type: String

The type of compilation mo or json

options.createJSFiles

Type: Boolean Default value: true

Only relevant when options.type is set to 'json'. If false the JS files won’t be created alongside the json. If you don’t need the js e.g. you’re not producing a client-side app that uses the JS then set this to false.

options.jsVar

Type: String Default value: json_locale_data

Allows you to override the JS var used in the JS output. The var is added to the window object. So by default you’ll end up with window.json_locale_data. This value is crudely validated to help ensure you don’t use a reserved word or an invalid property name.

options.localeDir

Type: String Default value: locale

The base locale directory.

options.lockFileName

Type: String Default value: grunt-i18n-abide.lock

An option to customise the lockfile name.

This can be useful if you might be running multiple builds concurrently on the same server. Set this to use an environment variable or use a grunt cli option so each job has a unique lockfile name.

A complete configuration example

grunt.initConfig({
  pkg: grunt.file.readJSON('package.json'),

  abideCreate: {
    default: { // Target name.
      options: {
        template: 'locale/templates/LC_MESSAGES/messages.pot', // (default: 'locale/templates/LC_MESSAGES/messages.pot')
        languages: ['en-US', 'fr', 'es'],
        localeDir: 'locale',
      }
    }
  },
  abideExtract: {
    js: {
      src: 'lib/**/*.js',
      dest: 'locale/templates/LC_MESSAGES/messages.pot',
      options: {
        language: 'JavaScript',
      }
    },
    html: {
      src: 'templates/payments/*.html',
      dest: 'locale/templates/LC_MESSAGES/messages.pot',
      options: {
        language: 'Jinja',
      }
    },
  },
  abideMerge: {
    default: { // Target name.
      options: {
        template: 'locale/templates/LC_MESSAGES/messages.pot', // (default: 'locale/templates/LC_MESSAGES/messages.pot')
        localeDir: 'locale',
      }
    }
  },
  abideCompile: {
    json: {
      dest: 'media/locale/',
      options: {
        type: 'json',
        createJSFiles: false, // defaults to true
      }
    },
    mo: {
      options: {
        type: 'mo',
      }
    }
  },
});

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.

Where to file bugs

Bear in mind this code only wraps jsxgettext and standard gettext tools. If there’s a problem with how grunt talks to jsxgettext or those CLI tools then that’s a problem with this package. However if the output is not correct (and it’s not related to configuration) please file a bug on the relevant project.
