Convert some variables.less to JSON to be used in Javascript

This plugin requires Grunt ~0.4.5

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-less2js --save-dev

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

grunt.loadNpmTasks('grunt-less2js');

In your project's Gruntfile, add a section named less2js to the data object passed into grunt.initConfig().

grunt.initConfig({
  less2js: {
    your_target: {
      options: {
        // Task-specific options go here.
      },
      // Target-specific file lists and/or options go here.
    },
  },
});

Type: String Default value: '// DO NOT EDIT! GENERATED AUTOMATICALLY with grunt-less2js'

A top banner at the generated file. Only applicable when options.format not "json"

Type: String Default value: 'json'

A type of output file contents. Available values: 'json' (basic valid json), 'ng' (angular-js module), 'commonjs' (node-js module), webjs (js to assign to window variable; see also windowVariable below)

Type: String Default value: ''

If a variable starts with the ignoreWithPrefix, it will be omitted from the JSON file. For example: _ would ignore @_base.

Type: Boolean Default value: false

Converts variable name into the camel-case format which is most convenient to use inside JSON/JS. Examples: @--foo-bar => fooBar, @foo-bar => fooBar, @--FooBarEXT => fooBarExt

Type: Boolean Default value: false

All data-types exported from less files are strings. The option converts string-numbers into ordinary decimal numbers (base 10).

Type: Boolean Default value: false

Less variables, defined as @myVar: "looks like a string" by default will be imported with redundant quotes. To avoid this crap, don't use quotes or enable this option to remove quotes from the beginning and end of the output string.

Type: Object Default value: null

Allows to modify (override or add) variables to resulted output json (after getting through all other passed options).

Type: String Default value: '%path to output file%'

A name of output angular.js module This option applicable only with options.format = 'ng'

Type: String Default value: '%output filename without extension%'

A name of constant service for the output angular.js module This option applicable only with options.format = 'ng'

Type: String Default value: less2js

The name of key on the global window to load the generated variables object.
This option applicable only with options.format = 'webjs'

  json: {
    options: {
      format: 'json'
