为了满足自己碰到的需求而基于grunt-sea-hashmap进行了调整，增加了map_realpath用来控制生成的map里面的路径是否使用实际路径。因为npm上已经有了grunt-sea-hashmap，所以为了引用的时候方便名字里追加了个z作以区别，其他内容沿用原版。具体可以直接查看原版官网。改版的代码是我fork了原版一份然后提交上去的，有兴趣的可以去 https://github.com/xuhuan/grunt-sea-hashmap 看。 # grunt-sea-hashmap

Generate a hash mapping for seajs modules when building, in order to burst cache.

Getting Started

This plugin requires Grunt ~0.4.4

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-sea-hashmap --save-dev

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

grunt.loadNpmTasks('grunt-sea-hashmap');

The "hashmap" task

Overview

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

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

Options

options.algorithm

Type: String Default value: 'md5'

Specific algorithm to generate hash.

options.encoding

Type: String Default value: 'utf8'

Specific file encoding.

options.map_tpl

Type: String Default value: path.join(__dirname, 'map.tpl')

Path of hash map template file.

options.MAP_FILE_RE

Type: RegExp Default value: /[^"]+\?\w+/g

RegExp to extract hash map from original config file. If hash doesn't changed, module file will not copy to build directory, that could reduce build task.

options.MAP_BLOCK_RE

Type: RegExp Default value: /\/\*map start\*\/[\s\S]*\/\*map end\*\//

RegExp to cut map config block, in order to insert a new map config block into the dest config file. It related with the content of map_tpl.

options.build_dest

Type: String

Destination of moudle files which should to build.

Usage Examples

grunt.initConfig({
  hashmap: {
    tests: {
        options: {
            build_dest: 'tmp/.build'
        },
        files: [
          {
            cwd: 'test/fixtures/page',
            src: '*.js',
            dest: 'tmp/map-config.js'
          }
        ]
    }
  }
})
