Fixes allowing source mapping to work

[dtilchin]

• filename is a required option to compile()
• Parens around a ternary, since ('name' + false ? '' : '.coffee') evaluates to '', not 'name.coffee'

Tested in Chrome 33 and Firefox 24. Without the first fix, the compile() fails because it tries to split() filename, which is undefined. See compile() in coffee-script.coffee in the CS source.

Hey, just checking in - it would be great to get this accepted to making distributing code that uses this easier.

I have a couple of questions:

Firstly, from the demo code we have in this project, I couldn't see any difference between the compiled files using the old cs.js and your patched cs.js.
Could you supply a small sample code which demonstrates what changes does your patch do to the compiled files?

Secondly, From #42

...it works pretty well - except for exceptions, where it always maps to one statement above the statement that caused the error, at the same indentation level.

I think we should document this short-coming (maybe an update to the readme?) for future reference or another patch.

This is super old, not even sure if it's an issue any more. It was a breaking issue, so I'm sure someone would have fixed it by now if so.

It's weird why I didn't merge the PR back then. The issue hasn't been fixed. Partly because this project and coffeescript to a lesser extent, is nearly dead for some time now. Really sorry. 😐

I could merge it now, if you would like @dtilchin.

Update - you'll just need to sign the CLA before I can merge it.
