grunt-patch Build Status
Grunt Patch is a grunt plugin which can be used to patch files using grunt.

Getting Started

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-patch --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-patch');

The "patch" task

Overview

In your project's Gruntfile, add a section named patch to the data object passed into grunt.initConfig().
grunt.initConfig({
  patch: {
    options: {
      patch: 'test/fixtures/default.patch'
    },
    files: {
      'tmp/output.default.patched': 'test/fixtures/input.default'
    }
  },
});

Options

options.patch

Type: String Default value: false
This is a string value which can either be the path of a patch file or the patch string itself. This is a required option.

Usage Examples

Default Options

In this example, the default options are used to patch an input file named input.default with default.patch to output a patched file named output.default.patched.
grunt.initConfig({
  patch: {
    options: {
      patch: 'test/fixtures/default.patch'
    },
    files: {
      'tmp/output.default.patched': 'test/fixtures/input.default'
    }
  },
});

Custom Options

In this example, the custom options are used to patch an input file named input.custom with the string mentioned in patch to output a patched file named output.custom.patched.
grunt.initConfig({
  patch: {
    default_options: {
      options: {
        patch: 'test/fixtures/default.patch'
      },
      files: {
        'tmp/output.default.patched': 'test/fixtures/input.default'
      }
    },
    custom_options: {
      options: {
        patch: "Index: input.custom\n" + 
               "===================================================================\n" + 
               "--- input.custom\n" + 
               "+++ input.custom\n" + 
               "@@ -1,7 +1,7 @@\n" + 
               " Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore.\n" +

      },
