javascript - grunt-concat 分隔符选项？

Question

在这种情况下如何指定分隔符:
我以这种方式将我的文件与 grunt-concat 连接起来:

concat: {
  options: {
    banner: '<%= banner %>',
    separator: ""
  },
  dist: {
    files:{
      '<%= distdir %>/public/scripts/ieditor.js': [
        'public/scripts/ieditor/vars.js',
        'public/scripts/ieditor/controllers/*.js',
        'public/scripts/ieditor/directives/*.js',
        'public/scripts/ieditor/app.js',
        'public/scripts/ieditor/services/*.js',
        'public/scripts/ieditor/filters/*.js'
      ],
      '<%= distdir %>/public/scripts/dashboard.js': [
        'public/scripts/dashboard/vars.js',
        'public/scripts/dashboard/controllers/*.js',
        'public/scripts/dashboard/directives/*.js',
        'public/scripts/dashboard/app.js',
        'public/scripts/dashboard/services/*.js',
        'public/scripts/dashboard/filters/*.js'
      ]
    }
  }
}

我想要的是在连接 CSS 文件时将最终结果映射到原始文件，如指南针。
示例:

//####public/scripts/ieditor/vars.js###############
content of public/scripts/ieditor/vars.js
//####public/scripts/ieditor/controllers/a.js######
content of public/scripts/ieditor/controllers/a.js
//####public/scripts/ieditor/controllers/b.js######
content of public/scripts/ieditor/controllers/b.js
.....

那么，要连接的当前文件的名称是什么，所以我可以在选项区域中执行类似的操作:

  options: {
    banner: '<%= banner %>',
    separator: "<%= current_file_name %>"
  },

提前致谢。

process option, specified as a function , 是你的 friend 吗:

concat: {
  options: {
    process: function(src, filepath) {
      return '//####' + filepath + '\n' + src;
    }
  }
},
