grunt-css-parse

Grunt plugin for css parse (https://npmjs.org/package/css-parse).

Getting Started

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-css-parse --save-dev

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

grunt.loadNpmTasks('grunt-css-parse');

The "css_parse" task

Overview

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

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

Options

options.space

Type: String Default value: null

A String or Number object that's used to insert white space into the output JSON string for readability purposes. If this is a Number, it indicates the number of space characters to use as white space; this number is capped at 10 if it's larger than that. Values less than 1 indicate that no space should be used. If this is a String, the string (or the first 10 characters of the string, if it's longer than that) is used as white space. If this parameter is not provided (or is null), no white space is used.

options.position

Type: Boolean Default value: false

Add the corresponding position in the css source file to each node.

Usage Examples

Default Options

In this example, the default options are used.

grunt.initConfig({
  css_parse: {
    dist: {
      files: {
        'dest/custom_options': ['src/custom_options.css']
      }
    }
  }
});

Input:

body {
    background: #eee;
    color: #888;
}

Output:

{"type":"stylesheet","stylesheet":{"rules":[{"type":"rule","selectors":["body"],"declarations":[{"type":"declaration","property":"background","value":"#eee"},{"type":"declaration","property":"color","value":"#888"}]}]}}

Custom Options

In this example, custom options are used.

grunt.initConfig({
  css_parse: {
    options: {
      space: 4,
      position: true
    },
    dist: {
      files: {
        'dest/custom_options': ['src/custom_options.css']
      }
    }
  }
});

Input:

body {
    background: #eee;
    color: #888;
}

Output:

    "stylesheet": {
        "rules": [
