Hi all, I use a bunch of Ruby Script and appscript-rb, together with a stand-alone keyboard shortcut app to integrate a number of Mac apps. ( http://reganmian.net/wiki/researchr:start). I am very interested in the possibility of porting this to MacRuby, because currently my biggest problem is the difficult other users have in installing this workflow (requiring XCode, binary gems, other applications etc). However, the two gems that I am absolutely dependent on are bibtex-ruby and citeproc-ruby. These both run extremely slowly on MacRuby. As a very simple example, here are the differences in running a script that only includes the lines include 'rubygems' include 'bibtex' (or 'citeproc') Ruby MRI 1.92p80: 0.18 and 0.36 MacRuby 0.12: 2.88 and .677 Running the parsing benchmarks for BibTeX in MacRuby is also 20-100 times slower. This makes it unusable for my purposes. I wonder how I can address this. The developer asked me for ruby-prof output, but I know that doesn't currently run on MacRuby. I have XCode and Instruments, but having never used XCode for ObjC development, I have no idea about how to configure Instruments to make it useful for his purposes. Any assistance would be greatly appreciated! Stian Haklev Curriculum, Teaching and Learning / University of Toronto -- http://reganmian.net/blog -- Random Stuff that Matters
