[MacRuby-devel] MacRuby gems running very slow, how to debug/improve

[Stian Håklev]

Hi Pim,

thank you very much for sharing this. However, one of the problems with
appscript is that it requires XCode to install, which many non-programmers
don't have installed (although it gets easier now that they separated the
command line compilers from the rest of the several gig XCode install). But
either way, there are other advantages of switching to MacRuby - for
example integrated global keyboard shortcuts (through a gem) - currently I
am using Keyboard Maestro for this, etc.

I really hope people could offer advice on how to help optimize these
libraries for MacRuby!
