MacRuby 0.5b1: Reloading classes at runtime
by Frank Illenberger 15 Nov '09

15 Nov '09

Hello folks, please excuse me if this is not the right mailing list to post this question: I am currently porting an application from PyObjC to MacRuby. Under PyObjC it is possible to reload a .py file containing a class definition at runtime. -[MacRuby evaluateFileAtPath:] works fine for me loading a class for the first time. But after is loaded, it is not updated when called again. Does anybody know if there is a way to make this work with MacRuby? Thanks and cheers Frank

Quicklook plugin, Spotlight importer
by B. Ohr 15 Nov '09

15 Nov '09

Hi, I have written a MacRuby class that reads binary data (a special format) from a file. Is there a chance that I can use this class in a Quicklook plugin or a spotlight importer? Both targets don't support GC-memory, but all object instances are created in one procedure with autorelease (NSAutoreleasePool ). So this is a very special case of GC.... Bernd

[MacRuby] #348: macruby is slower than ruby 1.9 for priority queue work

#348: macruby is slower than ruby 1.9 for priority queue work -------------------------------------+-------------------------------------- Reporter: jordan.breeding@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- I was originally trying to debug why a program I have that uses priority queues was breaking under MacRuby. I am still in the process of tracking that one down (to a reproducible, small test case). In the process however I ended up with two different pure ruby priority queues that I was using, and one Obj-C based priority queue. To further track down the problem I pulled out some of the code into a much smaller example. Unfortunately, this actually worked for all three cases reliably and I could not reproduce the crash. Fortunately it uncovered some cases where ruby 1.9 reliably performs better than MacRuby. I do not know if these cases are known or not, but I am including the timing information inline here as well as in text files in the zip file I am attaching. using a small set with pqueue {{{ (; ruby1.9 ./small_queue_test.pqueue > /dev/null; ) 11.63s user 0.05s system 99% cpu 11.691 total (; macruby ./small_queue_test.pqueue > /dev/null; ) 16.49s user 1.34s system 107% cpu 16.509 total }}} using a larger set with pqueue {{{ (; ruby1.9 ./small_queue_test.pqueue > /dev/null; ) 186.19s user 1.20s system 93% cpu 3:21.24 total (; macruby ./small_queue_test.pqueue > /dev/null; ) 219.19s user 17.70s system 105% cpu 3:45.16 total }}} using a small set with ruby_priority_queue {{{ (; ruby1.9 ./small_queue_test.ruby_priority_queue > /dev/null; ) 20.28s user 0.10s system 97% cpu 20.899 total (; macruby ./small_queue_test.ruby_priority_queue > /dev/null; ) 37.43s user 2.05s system 107% cpu 36.717 total }}} using a larger set with ruby_priority_queue {{{ (; ruby1.9 ./small_queue_test.ruby_priority_queue > /dev/null; ) 230.49s user 0.93s system 99% cpu 3:51.97 total (; macruby ./small_queue_test.ruby_priority_queue > /dev/null; ) 482.74s user 25.98s system 105% cpu 8:00.51 total }}} In the two files "small_queue_test.pqueue" and "small_queue_test.ruby_priority_queue" there is a variable at the top that controls the starting level for the nodes, a higher number means a larger set. The small set was run with a starting node of 9, and the larger set was run with a starting node of 10. -- Ticket URL: <http://www.macruby.org/trac/ticket/348> MacRuby <http://macruby.org/>
