Question

I’d like my rack application to be able to interface with a server-side javascript engine.

As of now the only way i know this could be possible, is by running JRuby and Rhino on the JVM, but I’m hoping for a leaner solution.

Has anyone heard of another, more rubyish perhaps, option ?

Edit : Reading the comments I’m starting to think I’ve been mistaken assumig that having both JRuby and Rhino run on the JVM would imply some interoperability between ruby and javascript…?
That’s not a desirable solution for me anyhow, but still i’d like to clear that up.

The Ruby Racer is now out of pre-alpha and is hovering somewhere between alpha and beta. It now supports:

• calling ruby code from javascript
• calling javascript functions from ruby
• embedding ruby objects into the javascript scope.
• letting ruby objects be your javascript scope
