OMeta JS 2.0

[josher19]

#1)
Started a JavaScript version of the compiler using OMeta JS 2.0:
http://www.tinlizzie.org/ometa-js/#Coffee

Currently sub-classing the Javascript Compiler, so it can execute CoffeeScript aliases or JavaScript, but may need to redo it as a complete compiler in order to do CoffeeScript Statements.
Not sure how much time I'll have to work on this, so anyone else is welcome to to take it over.

#2)
Suggest that Objects should be either CoffeeScript format OR standard JSON format to make it easier to read JSON directly without parsing to CoffeeScript or visa versa.

With the newlines it looks good, but I think
ages: {max: 10, ida: 9, tim: 11 }
is slightly more legible than
ages: { max: 10 ida: 9 tim: 11 }

#3)
In your Docs [ http://jashkenas.github.com/coffee-script/#array_comprehensions ]
Suggest you change the example from:

Eat lunch.

lunch: food.eat() for food in ['toast', 'cheese', 'wine'].

to something like:

Eat lunch.

lunch: eat(food) for food in ['toast', 'cheese', 'wine'].
eat: edible => log("yum: " + edible).
log: msg => if (window && window.console) console.log(msg) else alert(msg).

This works better than having to define eat in String.prototype.eat
Otherwise you end up eating Strings instead of Food! ;-)

1. Awesome! It's not often you can ask for something on a wishlist and have it come true.

   1. Leaving out the commas in array and object literals is only allowed in the newline form. I quite agree with you -- it doesn't make any sense in single-line objects. Note that you're allowed to mix and match:

      matrix: [
      0, 1, 1
      1, 1, 0
      1, 0, 1
      ]

2. I've changed the example -- it'll go out with the next release. Thanks for the doc fix.

This ticket has been superseded by the "CoffeeScript in CoffeeScript" one, which may or may not use OMeta for the parser.
