带有 Grunt Uglify 的动态文件名

Question

I am trying to set the version in the filename with Grunt Uglify, but it doesn't accept anything other than a string literal.

How can I replace "VERSION" dynamically by using a variable (eg ${VERSION} ), or better yet, a command line argument?

grunt.initConfig({

  uglify: {
    min: {
       options: {}
      ,files: {
        "jquery.project-VERSION.min.js" : [ "jquery.project.js", "modules/*.js" ]
      }
    }
    ,dev: {
       options: {
        beautify: {
          width: 80
        }
      }
      ,files: {
        "jquery.project-VERSION.dev.js" : [ "jquery.project.js", "modules/*.js" ]
      }
    }
  }
});

As pointed out in a comment by @cartant, this can be done with a Grunt template, eg <%= version %>

So in my case it was

grunt.initConfig({

   version: 1.2.3    

  ,uglify: {
    min: {
       options: {}
      ,files: {
        "jquery.project-<%= version %>.min.js" : [ "jquery.project.js", "modules/*.js" ]
      }
    }
    ,dev: {
       options: {
        beautify: {
          width: 80
        }
      }
      ,files: {
        "jquery.project-<%= version %>.dev.js" : [ "jquery.project.js", "modules/*.js" ]
      }
    }
  }
});
