About HOC ========= HOC is a Haskell to Objective-C binding. In a nutshell, it enables you to use Objective-C objects and frameworks from Haskell, and also enables you to write Objective-C objects in Haskell. You can write full-blown applications in HOC and use all of the Foundation, AppKit and Cocoa frameworks' classes (including all of the AppKit's GUI objects), combining Objective-C tools such as Mac OS X's Interface Builder to build the GUI graphically while writing controllers for the GUI in Haskell. You can even mix and match custom objects written in Objective-C with objects written in Haskell, depending on which language you find more suitable for the task. HOC comes some sample GUI programs: you can find screenshots of these HOC programs at <http://hoc.sourceforge.net/screenshots/>. The Haskell interfaces produced by HOC are strongly typed (Objective-C classes are mapped to Haskell's typed system), can be automatically generated from Objective-C header files, and are designed to integrate well with existing Haskell code, taking advantage of features such as type classes and partial application to make its Haskell API as easy to use and as "Haskell-like" as possible. HOC's primary platform is Mac OS X, although it has been lightly tested with the free GNUstep platform on Linux. HOC requires the Glasgow Haskell Compiler (GHC) 6.2 or later. Note: If you have heard of a Haskell to Objective-C binding named Mocha, HOC is effectively a working version of Mocha, which was never completed due to time constraints. A previous version of HOC (0.1) was mentioned briefly on the glasgow-haskell-users mailing list on January 2003, but is a very different beast to the current incarnation: HOC 0.1 was more of an experiment with Template Haskell than a serious implementation. Wolfgang Thaller, the primary author of HOC, has collaborated greatly with Andre Pang, who was the primary author of Mocha, to forge a new HOC that we hope you will find achieves all the ambitious goals that Mocha strived for, and more. Mocha is dead, long live HOC! More information on HOC (including where you can download it!) is available on its homepage, at: http://hoc.sourceforge.net/ Authors ======= Wolfgang Thaller <wolfgang.thaller@gmx.net> Andre Pang <ozone@algorithm.com.au> Enjoy! -- % Andre Pang : trust.in.love.to.save
