Hi all, first time caller here. Came back to check in on this thread due to some interest in the library that Mac has been working on - and the discussion about Objective-C/Cocoa interfacing has prompted me to break cover with something I've been hacking around on for the past few weeks.
Basically I've been working on a bridge between Clojure and Objective-C/Cocoa. While my bridge does at its heart use JNA, I've taken a somewhat different approach from the one Mac is recommending. I'd describe the current state of it as "demo" quality - it works for the demo code, but try anything else and you're on your own. More details can be found at http://github.com/allertonm/Couverjure Cheers ..Mark.. On Sun, Jan 10, 2010 at 1:47 PM, mac <markus.gustavs...@gmail.com> wrote: > > This is great.
