Dear all,

I'm pleased to announce CocoaGap: a native Macintosh OS X GUI for GAP. Version 0.1 is available for download now from SourceForge at

http://cocoagap.sourceforge.net/



Currently, CocoaGap is an almost feature-complete replacement for xgap. It allows interaction with the GAP command line, display of subgroup lattices, inspection of subgroups, and most other features supported by xgap. It is probably lacking a few features: command- line completions is one that I am aware of.

It also has some improvements over running xgap under Apple's X11 environment. At this time, these are mostly by-products of being a native program -- Cut/Copy/Paste work as one would expect, the save dialogs are native (with access to favorites, etc). There is also the beginnings of a preferences dialog, and a progress bar while loading the GAP library on startup.

I hope to make further improvements to CocoaGap as time goes on. The Cocoa libraries are quite a bit richer than the X11/Athena libraries, which should make it easy to add such things as an in-program html help browser, an application bundle for the entire GAP system, etc. However, it's likely to be a while before I have time to add such features, and what exists now works well enough to be helpful. I have been using it as my main GAP environment for the last couple of months, and found it to generally work well.

I would appreciate any comments or suggestions.

        Sincerely,

                                                --Russ
