What Hacker News says
6 sourcesObjective-J is decoupled from Cappuccino. It runs completely independently, and even has a command line utility available built on top of Narwhal (a command line JS environment we built before Node was an option). Objective-J should absolutely be made to run on node, and that's being done as part of our rewrite, Objective-J 2.0.
As far as the other direction is concerned, you can write code on top of the Cappuccino framework in any language you can get running in the browser. The problem with writing in vanilla JavaScript, as opposed to Objective-J, is just that there are missing features which require the use of fairly obnoxious syntax in JavaScript.
A ruby to JavaScript compiler would provide a great language alternative to Objective-J for targeting Cappuccino. In fact, you can build a reasonable subset of ruby on top of Objective-J (se

There are a number of existing projects that compile a partial Ruby into JS:

* https://github.com/jessesielaff/red
* https://github.com/tlrobinson/cappruby
I'm afraid that Ruby semantics don't align too well with JavaScript semantics. Things as basic as numbers, method dispatch, and variable scoping don't work the same way. Either you end up with perfectly valid code written in one that doesn't run on the other, or you have an extremely slow Ruby interpreter implemented on top of JavaScript.
This is the main reason why CoffeeScript tries to stick as close to JavaScript as possible.
In CoffeeScript hits 1.0 -- Happy Holidays, HNI'm sure you're all getting sick of me posting this link, but this is relevant:

It's the same idea but it uses the Objective-J runtime which is similar to Ruby's runtime.
In Convert Ruby to JavaScriptFun stuff. I've got a similar proof-of-concept project for Ruby, called "CappRuby" which targets the Objective-J runtime (not unlike how MacRuby targets the Objective-C runtime):

In Python, client side: SkulptCappuccino meets Ruby: http://github.com/tlrobinson/cappruby
It's very incomplete... a proof of concept.
