如何避免多个帮助实现像__indexOf（）与grunt-contrib-coffee [英] How to avoid multiple helper implementations like __indexOf() with grunt-contrib-coffee

问题描述

我有一个 Gruntfile.coffee ，有 grunt-contrib-coffee 配置如下：

I have a Gruntfile.coffee that has a grunt-contrib-coffee configuration like this:

coffee:
  compile:
    files:
      'public/assets/application.js': [
          'multiple/files' #, ...
      ]
    options:
      bare: true

问题是，它会生成多个辅助方法实现，例如

The Problem is, that it generates multiple implementations of helper methods like

    var __indexOf = [].indexOf || function(item) { for (var i = 0, l = this.length; i < l; i++) { if (i in this && this[i] === item) return i; } return -1; };

如何让它识别这些实现已经编译？

How to make it recognize that these implementations are already compiled?

原因很明显，编译的JavaScript在编译之后被连接起来。如果CoffeeScript在编译之前被拼接，那么可以避免这种情况。如果这不是我缺少的 grunt-contrib-coffee 的配置选项，我会在github上提交一个问题。

The reason is obviously that the compiled JavaScript gets concatenated after it got compiled. It could be avoided if the CoffeeScript would be concatenated before compiling it. If this is not a configuration option of grunt-contrib-coffee that I'm missing, I'll submit an issue on github.

因此，剩下的问题是：如何在编译之前连接CoffeeScript，避免多个辅助实现？

So the question that remains is: how to concatenate the CoffeeScript before compiling it, to avoid multiple helper implementations?

有一个解决方法，它涉及将源文件手动连接到 concat 任务。这需要一个临时文件，然后可以从CoffeeScript编译为JavaScript。在我创建的问题中提及。

There is a workaround, which involves manual concatenation of the source files with the concat task. This requires a temporary file, that can then be compiled from CoffeeScript to JavaScript. It is mentioned in the issue I created.

在将来，任务将能够将他们的东西作为缓冲区传递给对方（参见 issue ）。

In future, tasks will be able to pass their stuff as buffers to each other (see the issue).

推荐答案

Grunt-contrib-coffee-0.6 .1这适用于加入选项：

As of grunt-contrib-coffee-0.6.1 this works with the join option:

coffee:
  compile:
    files:
      'public/assets/application.js': [
          'multiple/files' #, ...
      ]
    options:
      bare: true
      join: true # concatenate coffee files before compiling. default is false
