Precompile Handlebars templates for Ember.js.

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-ember-templates --save-dev

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

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

This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that you upgrade, but in case you can't please use v0.3.2.

Inside your Gruntfile.js file, add a section named emberTemplates. This section specifies the files to compile and the options used with handlebars.

This defines what files this task will process and should contain key:value pairs.

The key (destination) should be an unique filepath (supports grunt.template) and the value (source) should be a filepath or an array of filepaths (supports minimatch).

Note: Values are precompiled to the Ember.TEMPLATES array in the order passed.

This controls how this task operates and should contain key:value pairs, see options below.

This option accepts a function which takes one argument (the source template filepath) and returns a string which will be used as the key for the precompiled template object. The example below strips away the root path from templates so their names will match Ember's conventions:

options: {
  templateName: function(sourceFile) {
    return sourceFile.replace(/path\/to\/templates\//, '');
  }
}

emberTemplates: {
  compile: {
    options: {
      templateName: function(sourceFile) {
        return sourceFile.replace(/path\/to\//, '');
      }
    },
    files: {
      "path/to/result.js": "path/to/source.handlebars",
      "path/to/another.js": ["path/to/sources/*.handlebars", "path/to/more/*.handlebars"]
    }
  }
}

Here's an example task that watches for changes to your templates and automatically recompiles them:

watch: {
  emberTemplates: {
    files: 'app/scripts/**/*.handlebars',
    tasks: ['emberTemplates', 'livereload']
  },
}

Many thanks to the following projects upon which this was based:

• grunt-contrib-handlebars by Tim Branyen
• grunt-ember-handlebars by Mukund Lakshman

I created this project as an alternative to grunt-ember-handlebars for the following reasons:

• to provide maximum compatibility with the grunt-contrib project, using features such as destination:source file arguments
• to allow for customizable template names based upon source file paths
