red

Cool idea. Not the first attempt though: http://hotruby.yukoba.jp/ https://github.com/whitequark/coldruby http://rb2js.rubyforge.org/ http://www.ntecs.de/blog/articles/2007/01/08/rubyjs-javascri... https://github.com/jessesielaff/red http://www.playmycode.com/docs/quby https://github.com/mattknox/8ball Unfortunately, none of them seem to be to handle the mor dynamic features of ruby, like method_missing, which diminishes the possibility of reusing existing ruby code in the browser.

There are a number of existing projects that compile a partial Ruby into JS: * https://github.com/superchris/rubyjs * 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.

Just a note that this is three years old and somewhat outdated, but... it's still a pretty cool trick/idea, similar to the Ruby->PHP compiler mentioned here recently: http://www.ruby-php.org/ I'm not sure, though, that it's useful enough to "break through." judofyr mentioned Red ( http://github.com/jessesielaff/red ) as a more production ready Ruby-JavaScript tool but even that hasn't been updated in a year it seems :-(

It reminds me Red(http://github.com/jessesielaff/red/tree/master) but for CSS.
