    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-lint-pattern --save-dev

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

    grunt.loadNpmTasks('grunt-lint-pattern');

    The "lint_pattern" task

    Overview

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

    grunt.initConfig({
      lint_pattern: {
        your_first_target: {
          options: {
            rules: [
              {
                pattern: /console\./,
                message: 'Do not call "console".'
              },
            ],
          },
          files: {
            '**.js',
          },
        },
        your_second_target: {
          options: {
            rules: [
              {
                pattern: /moz-border-radius/,
                message: 'Do not use vendor prefixes for the border-radius property.'
              },
              {
                pattern: /!important/,
                message: 'Do not use "!important".'
              },
              {
                pattern: /@import\s+/,
                message: 'Do not use import statements',
                filter: function(src) {
     
                }
              },
            ],
          },
          files: {
            '**.css',
          },
        },
      },
    })

    Options

    options.rules

    Type: Array Required

    An array of "rules" that will be used to test files. Rules have the form:

    pattern

    Type: RegExp Required

    A RegExp that will be used to test files.

    pattern

    Type: string Optional

    A message that will print when pattern is found.

    filter

    Type: function Optional

    If present, this function will be called once for each matching file to decide whether to test this rule. Return true to allow checking this file. Return false to skip checking this file.

    This is particularly useful if you are checking a large list of rules over a large list of files and a small number of files that should be excluded by certain rules. The advantage of filtering out the few exclusions compared to creating multiple targets is that the files need only be read from disk once if there's a single target.
