I have used MacRuby in the past with good success. I like its technique of using ObjC as the underlying "VM", using pure ObjC objects.
Unfortunately, it's impractical to write the majority of a Mac or iOS app using anything other than Xcode + ObjC, especially the UI. So the goal of this endeavor would mainly be to write command line utilities in Clojure or embed scripting capabilities into your app that understands Clojure. -Steven On Tue, Apr 23, 2013 at 4:39 PM, Rich Morin <r...@cfcl.com> wrote: > On Apr 23, 2013, at 12:38, Steven Degutis wrote: > > Currently Clojure exists on the JVM, the CLR, and the JSVM. > > > > Why not put it on top of ObjC too? > > +1 > > I'd be delighted to have such a port.
