grunt-sprockets-directives

Dependency management using Sprockets directives.

Getting Started

This plugin requires Grunt ~0.4

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-sprockets-directives --save-dev

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

grunt.loadNpmTasks('grunt-sprockets-directives');

Sprockets Directives

You can use the following directives to declare dependencies in asset source files.

For directives that take a path argument, you may specify either a logical path or a relative path. Relative paths begin with ./ and reference files relative to the location of the current file.

The require Directive

require path inserts the contents of the asset source file specified by path. If the file is required multiple times, it will appear in the bundle only once.

The include Directive

include path works like require, but inserts the contents of the specified source file even if it has already been included or required.

The require_directory Directive

require_directory path requires all source files of the same format in the directory specified by path. Files are required in alphabetical order.

The require_tree Directive

require_tree path works like require_directory, but operates recursively to require all files in all subdirectories of the directory specified by path.

The require_self Directive

require_self tells Sprockets to insert the body of the current source file before any subsequent require or include directives.

The stub Directive

stub path allows dependency to be excluded from the asset bundle. The path must be a valid asset and may or may not already be part of the bundle. Once stubbed, it is blacklisted and can't be brought back by any other require.

The "directives" task

Overview

In your project's Gruntfile, add a section named directives to the data object passed into grunt.initConfig(). Only one src file is allowed per target.

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

Options

This task will resolve all dependencies, concatenate files using Grunt concat. Aside from the options outlined below, all concat options are accepted as well.

options.cwd

Type: String Default value: <cwd of your_target.src>

Relative dependencies will be matched relative to this path.

Usage Examples

Default Options

In this example, the default options are used to resolve dependencies. All dependencies are concatenated using concats default options.

grunt.initConfig({
  directives: {
    files: { 'dest/output': 'src/input' },
  },
});

Custom Options

In this example, custom options are used to resolve dependencies. The relative path for all dependencies is src. When concatenating, an intro.txt and outro.txt are added.

grunt.initConfig({
  directives: {
    options: {
      banner : grunt.file.read('intro.txt'),
      footer : grunt.file.read('outro.txt')
    },
    files: {
      options : { cwd: './src' },
      src     : 'src/input',
      dest    : 'dest/output'
    },
  },
});

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.
