grunt-coffee-strip-code

A Grunt task to remove develop and test only code blocks from CoffeeScript files for production build.

Getting started

Requirements: Grunt ~0.4.1 or above

Install in your workspace project

$ cd ~/your/workspace/project
$ npm install grunt-coffee-strip-code --save-dev

then add line to Gruntfile.js:

grunt.loadNpmTasks('grunt-coffee-strip-code');

The "coffee_strip_code" task

Overview

In Gruntfile.js add section named coffee_strip_code to the data object passed into grunt.initConfig().

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

Options

options.start_comment_tag

Type: String

Default value: test-block-start

The text inside the opening comment used to identify code to strip.

options.end_comment_tag

Type: String

Default value: test-block-end

The text inside the closing comment used to identify code to strip.

options.pattern

Type: RegExp Default value: (a generated RegExp matching the start and end comments)

If the default start and end comment matching doesn't work for your needs, you can supply your own RegExp to match against. If the pattern option is specified, the start_comment and end_comment options are ignored.

Example Usage

The following source code exposes the bar function to the public API for testing, but the bar function should not be accessible in the released library. grunt-coffee-strip-code (with the default options) will remove the comment blocks from the example below keeping the bar function private in production:

( () ->

  bar = () ->
    doSomething()

  api = {
    foo: () ->
      bar()
    }
  }

  ## test-block-start ##
  api._bar = bar;
  ## test-block-end ##

  return api;
)()

Setting custom start/end comment tag

The following configuration will strip out code that begins with the /* start-test-block / comment and ends with the / end-test-block */ comment from all .js files in the dist/ folder.

grunt.initConfig({
  coffee_strip_code: {
    options: {
      start_comment_tag: 'test-block-start',
      end_comment_tag: 'test-block-end',
    },
    src: 'dist/*.coffee'
  },
})

Customize own pattern

The following configuration will remove log() statements from all .js files in the dist/ folder

grunt.initConfig({
  coffee_strip_code: {
    options: {
      pattern: /log\(\)/g
    },
    src: 'dist/*.coffee'
  },
})

Specifying source and destination.

The normal behavior is to strip out code in the source files and then save those files with the same name. If you need to save them to a different name, you can specify a dest option as well.

grunt.initConfig({
  coffee_strip_code: {
    options: { },
    files: [
      {src: 'tmp/my-app.coffee', dest: 'dist/my-app.coffee'},
      {src: 'tmp/my-lib.coffee', dest: 'dist/my-lib.coffee'},
    ],
  },
})

Contribute

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.
