grunt-i18nTemplates

`TASK STEP 1`

Join all your templates files in a single json file so it is easy to access all the templates from javascript.

 // index.html
 "<html><body><h1>[[title: Hello World]]</h1> .....</body></html>"
 
 // form.html
 "<for><inpup> ...... </form>"

Result templates.json

 // i.e. : joined  index.html and form.html
 // result file: 
 {
   "index":"<html><body><h1>[[title: Hello World]]</h1> .....</body></html>",
   "form":"<for><inpup> ...... </form>"
 }

`TASK STEP 2`

Parses template files looking for locale-Definitions [[key: text]], and Generates localization files that contais the string to translate.

 index.html locale definition => [[title: Hello World]]
 
 form.html locale definition => none

Parsing the two example files generate the next localization files when options.locales is set to ["EN","ES"]

 // EN_locales.json  
 {
   "index:title":"Hello World"
 }
 
 // ES_locales.json
 {
   "index:title":"Hola Mundo" //this is the translation
 }

`TASK STEP 3`

Reads the values in the localization files and use them to generate the translated template files. i.e EN_templates.json and ES_templates.json.

 // EN_templates.json
 {
   "index":"<html><body><h1>Hello World</h1> .....</body></html>",
   "form":"<for><inpup> ...... </form>"
 }
 // ES_templates.json
 {
   "index":"<html><body><h1>Hola Mundo</h1> .....</body></html>",
   "form":"<for><inpup> ...... </form>"
 }

features

Join all templates in a single templates.json file, so it is more easy to access from javascript.
Automatically generate localization files.
Compatible with multiple template engines. Translation is done statically so the result can be used by any template engine.
Never override the sentences edited in the locale files. it is posiible to run this task at any time, the values in the localization files will never be overwritten, but new templates or new locale-Definitions will be added.

Generated templates

All templates are joined in the file templates.json. This file is never translated and always reflect the last estate of the templates, templates.json can be used in system where no translation is equired and you only want the join templates functionality. All the others Xlang_templates.json uses the values stored in the localization files.

If the value of one locale-Definition is changed in one file, i.e from [[title: Hello]] to [[title: Bye]] this change is not reflected in the translated templates Xlang_templates.json becouse this are using the values previously stored in the localization files. this change will be reflected only in templates.json.

Using the generated code.

i.e: using Jquery and mustache

//this is the english template file generated by 
//this task and contains all you templates.
var EN_templates = "./templates/EN_templates.json";
jQuery.getJSON(templateFile, function(data){
      /* data contains all the templates */
      var templates = data;
      Mustache.render(EN_templates.index,{});
});

GRUNT TASK CONFIGURATION

This plugin requires Grunt ~0.4.5

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-i18nTemplates --save-dev

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

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

The "i18nTemplates" task

Overview

In your project's Gruntfile, add a section named i18nTemplates to the data object passed into grunt.initConfig().

grunt.initConfig({
  i18nTemplates: {
  	options: {
    	locales: ["en","es","de"],
        templatesDest: "./public/templates", //this is where the translated templates will be generated
        localesDest: "./src/locales"  //this is where translation files will be stored	
   	},
  	your_target: {
       src: ['./src/templates/**/*.html']
    },
  },
});

Options

options.templatesDest

Type: String Default value: none, this value is required and not set by default.

A path to the templates folder.

options.localesDest

Type: String Default value: none, this value is required and not set by default.

A path to the locales folder.

options.locales

Type: Array Default value: none

An Array defining all the languages. i.e: ["en","es","de"]

Usage Examples

This example will generate 4 locale files in the ./src/locales folder (one for each language), and will generate 5 templates files in the ./public/templates, (one for each language + the one without translate).

grunt.initConfig({
  i18nTemplates: {
  	options: {
    	locales: ["en","es","de"],
        templatesDest: "./public/templates", 
        localesDest: "./src/locales" 	
   	},
  	your_target: {
       src: ['./src/templates/**/*.html']
    },
  },
});
