How to hook into Grunt events.

gruntEvents.coffee

  ['warn', 'fatal'].forEach (level) ->
    grunt.util.hooker.hook grunt.fail, level, (opt) ->
      require('growl')(opt.name,
        title: opt.message
        image: 'Console'
      )

  ['warn', 'error'].forEach (level) ->
    grunt.util.hooker.hook grunt.log, level, (opt) ->
      require('growl')(opt.name,
        title: opt.message
        image: 'Console'
      )

  grunt.event.on 'coffeelint:warn', (err, msg) ->
    require('growl')(msg,
      title: msg
      image: 'Console'
    )
    
  grunt.event.on 'coffeelint:any', (status, message) ->
      grunt.config ['notify', 'coffeelint'], options:
          title: "Coffeelint #{status}"
          message: message
      grunt.task.run 'notify:coffeelint'
