__bind not generated in coffeescript

[tanepiper]

In my coffeescript code, within my coffeekup template, => does not generate the __bind function within the script tag.

For example:

coffeescript ->
    foo = ->
        bar = 1
        baz = =>
            console.log bar

    foo().baz()

Exception thrown is Uncaught ReferenceError: __bind is not defined

The output is

;(function () {
    var foo;
    foo = function() {
        var bar, baz;
        bar = 1;
        return baz = __bind(function() {
            return console.log(bar);
        }, this);
    };
    return foo().baz();
})();

fwiw, the workaround is to add it through a script tag

script "__bind = function(fn, me){ return function(){ return fn.apply(me, arguments); }; };"

or maybe just include underscore.js

Same thing for me, I'm too new to CS to know when/why it decides to generate the bind function, but I would guess that the compiler thinks it's already generated? (p.s. Thanks for the workaround!)

I fixed this in 0.2.4beta by including all coffeescript helpers in code generated by the coffeescript "tag". But maybe it's a better idea to keep the original behavior of generating "clean" code and requiring the addition of the helpers manually. What do you guys think?

[bmidgley]

I prefer the automatic code generation. I noticed another of these popped up when I did an "if x in y" so it will be nice to have that work as well without tinkering.

Automatic it remains then. After all, now thinking, 635 bytes are not that of an issue.
