摆脱 CoffeeScript 的闭包包装 [英] Getting rid of CoffeeScript's closure wrapper

问题描述

我怎样才能省略在全局范围内隐藏我的变量的自动闭包包装器?

How can I omit the automatic closure wrappers that hides my variables from the global scope?

(function() {
  // my compiled code
}).call(this);

只是在使用 CoffeeScript+SproutCore，当然，我更愿意保持原样:在这种情况下，不需要保护任何内容不被覆盖.

Just playing around with CoffeeScript+SproutCore, and of course, I'd prefer to leave the scope as it is: in this case there is no need to protect anything from overwriting.

我知道我可以在声明中使用 @ 或 this.，但这不太优雅.

I know I can use @ or this. at the declaration, but that's not too elegant.

推荐答案

快速而肮脏的解决方案:使用控制台标志 -b(裸).警告:如果你这样做，小猫会死！

Quick and dirty solution: Use the console flag -b (bare). Warning: Kittens will die if you do that!

干净的解决方案:不要那样做.

Clean solution: Don't do that.
