grunt-coffee-chain

grunt plugin inspired by Sprockets to compile CoffeeScripts that has sprockets-style comments to indicate dependencies.

Usage (script-side)

In your CoffeeScript files, write Sprockets-style comments to indicate dependencies, e.g.

#= require dependency

If you want to bring in a whole folder of scripts, use

#= require_tree dir

Usage (grunt-side)

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-coffee-chain --save-dev

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

grunt.loadNpmTasks('grunt-coffee-chain');

The "coffeeChain" task

Overview

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

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

Options

options.clean

(Not yet implemented) Type: Booleann Default value: false

A boolean value that is used to clean resulting CoffeeScript from useless code that coffee compiler adds.

Usage Examples

Default Options

In these examples, the default options are used to compile coffee scripts to js without cleaning them`

grunt.initConfig({
  coffeeChain: {
    options: {},
    your_target: {
      src:  'app/assets/javascripts/main.coffee',
      dest: 'public/assets/app.js'
    }
  },
})

grunt.initConfig({
  coffeeChain: {
    your_target: {
      src:  'app/assets/javascripts/main.coffee',
      dest: 'public/assets/app.js'
    }
  },
})

Custom Options

In this example, the custom options are used to compile coffee scripts to js cleaning them`

grunt.initConfig({
  coffeeChain: {
    your_target: {
      options: {
        clean: true
      },
      src:  'app/assets/javascripts/main.coffee',
      dest: 'public/assets/app.js'
    }
  },
})

CoffeeScript Examples

In this example, the custom options are used to compile coffee scripts to js minifying and cleaning them`

grunt.initConfig
  coffeeChain:
    dist:
      options:
        clean: true
      src: "app/main.coffee"
      dest: "dist/index.js"

Contributing

This application is written in CoffeeScript with sprockets-style comments to indicate dependencies and so

it compiles itself to javascript using previous version of itself.

When you change something in this app it is better to compile tests using previous version of this app as we use coffee_chain to compile coffee_chain to itself and need to protect us from testing application using incorrectly compiled tests. So to run tests I have added a simple script that should be used instead of 'npm test' command:

  ./compile

Release History

version 1.2.5 - Current. Updated coffeeChain to save all data to a temp file and only when everything is complete overwrite the destination file
