If you're interested in developing OS X applications with a lisp, you should check out Nu — <a href="http://programming.nu" rel="nofollow">http://programming.nu</a> — It's a Cocoa-native language built on the Objective-C runtime, that's flavored somewhat like Common Lisp.<p>Additional info:<p>● A talk by the gentleman who created Nu, Tim Burks, talking about why he did so: <a href="http://www.viddler.com/explore/rentzsch/videos/13" rel="nofollow">http://www.viddler.com/explore/rentzsch/videos/13</a><p>● The Google Group for Nu: <a href="http://groups.google.com/group/programming-nu" rel="nofollow">http://groups.google.com/group/programming-nu</a><p>● The source (Apache License) on Github: <a href="https://github.com/timburks/nu" rel="nofollow">https://github.com/timburks/nu</a>
There is an interresting development (but haven't checked it lately) for using Cocotron (Cocoa clone) for Windows for ClozureCL.<p>What's really cool, is that while Objective-C Win32 applications written with Cocotron must be compiled under OSX (using gcc-mingw tools), this allows you to write them under Win32, because it uses the produced DLLS (AppKit.dll, Foundation.dll) and you communicate with lisp with them.<p>There is one thing to note - ClozureCL has 32-bit and 64-bit executables, but for some reason the 32-bit produced ones do not work on 64-bit.<p>That might be fixed already, I have to check again.
