* Intro CCL and LispWorks and other implementations have their own bridges to the objective-c runtime. This project is an attempt to create a bridge that only uses CFFI so that arbitrary lisp implementations can produce native mac GUIs. In the long run, I hope to use this as the basis for a new mac-native backend for McClim: but we'll see if that ever happens. For the time being, though, this only works on CCL and (sort-of) on LispWorks: it works like 95% on SBCL, but there's some weird issue that's preventing the window from showing. I hae not tested the code on any other implementations, but doing so will require changing a couple places in objc-runtime.lisp to inform the code about the new lisp's ffi types. * Installing 1. clone fwoar.lisputils from and put it somewhere quicklisp can find it (e.g. ~/quicklisp/local-projects) 2. clone cffi from and put it in the same place (on Big Sur, at least, I need changes that haven't made it to Quicklisp) 3.
