A few additional options are supported:

force

Type: Boolean Default value: false

Set force to true to report CoffeeLint errors but not fail the task.

Configuration

coffeelint is a multitask, so you can use it similary to lint, watch etc...

grunt.initConfig({
    ...
    coffeelint: {
      app: ['app/*.coffee', 'scripts/*.coffee']
    },
    ...
});

Options per target

grunt.initConfig({
    ...
    coffeelint: {
      app: ['app/*.coffee', 'scripts/*.coffee'],
      tests: {
        files: {
          src: ['tests/*.coffee']
        },
        options: {
          'no_trailing_whitespace': {
            'level': 'error'
          }
        }
      }
    },
    ...
});

Global - default options

grunt.initConfig({
    ...
    coffeelint: {
      options: {
        'no_trailing_whitespace': {
          'level': 'error'
        }
      }
    },
    ...
});

Loading external config

grunt.initConfig({
    ...
    coffeelint: {
      options: {
        configFile: 'coffeelint.json'
      }

Task options take precedence over configFile options.
