coffeescript compatibility

[heartsentwined]

Does ember-script preserve the full set of coffeescript syntax?

I tried it today and the compiler caught a couple of unexpected errors (all compiling fine in coffee-script:

ActionView::Template::Error (Error: Syntax error on line 84, column 5: unexpected '.' (\u002E)
81 : 
82 :     $.ajax
83 :       url: 'foo'
84 :     .done ->
^^ :~~~~^
85 :       doSomething()
86 : 

An explicit bracket resolves the above:

    $.ajax(
      url: 'foo'
    ).done ->
      doSomething()

ActionView::Template::Error (Error: Syntax error on line 18, column 19: unexpected '=' (\u003D)
17 : 
18 :     if foo && bar = 'value'
^^ :~~~~~~~~~~~~~~~~~~~^
19 :       doSomething()

Again an explicit bracket resolves it:

    if foo && (bar = 'value')
      doSomething()

These may very well be related to CoffeeScriptRedux rather than EmberScript. One of CSR's aims is to iron out any of the corner case language quirks of the original CS compiler, and these changes might be the result of it. That said, I am surprised that your ajax example doesn't work...

Thanks @machty, I'll give CSR a try, and possibly move this issue over there.

Found the first issue at michaelficarra/CoffeeScriptRedux#45 and michaelficarra/CoffeeScriptRedux#153

The other one is a new issue, opened at michaelficarra/CoffeeScriptRedux#189.

Closing and my apologies, I didn't realize this would be related to general issues from CSR - I thought it would be 100% backwards compatible.
