by Laurent Sansonetti 09 Jan '11

09 Jan '11

Hi guys, As of trunk, macgem is now rubygems 1.4.1. I did some preliminary tests before committing the merge and everything seems good, but I would prefer to get more feedback before releasing 0.9. If you can, please install trunk or grab the next nightly build, try macgem, and report any problem you find :) Mahalo, Laurent

Deploying a MacRuby.app with the GCD Dispatch gem
by Arron Mabrey 08 Jan '11

08 Jan '11

I want to use the Dispatch gem in my MacRuby.app. https://github.com/gunn/Dispatch The gem is installed. However I'm having problems just requiring it. # app_controller.rb require 'rubygems' require 'dispatch' Errors out with. /Users/arron/code/MyApp/build/Debug/MyApp.app/Contents/Resources/rb_main.rb:18:in `block': no such file to load -- dispatch (LoadError) from /Users/arron/code/MyApp/build/Debug/MyApp.app/Contents/Resources/rb_main.rb:16:in `<main>' What are the proper steps to require a gem within a Xcode project? Is it necessary to require rubygems? Also what are the proper steps to include the gem in the app to resolve dependancies at deployment? Arron Mabrey

How do you do this? [NSNumber numberWithDouble:NAN] NAN is defined as __builtin_nanf("0x7fc00000") in math.h Thanks, Joel --- http://wagerlabs.com | @wagerlabs | http://www.linkedin.com/in/joelreymont

csv.rb oddity
by Buddy Lindsey, Jr. 07 Jan '11

07 Jan '11

I am not sure if I am just doing something wrong or what, but I am trying to read in a CSV file and it seems the code I use for ruby 1.9.2 works fine, but not in MacRuby. I think I am doing something wrong, but not quite sure what since I am still new to MacRuby and getting familiar with it. I have put the following code in 'irb' and it works just fine and spits out the first part of the array. CSV.open('save.csv', 'r') do |row| row[1] end With irb I get smith smith smith using 'macirb' I get this. NoMethodError: undefined method `[]' for #<CSV:0x2005c9a20> /Library/Frameworks/MacRuby.framework/Versions/0.8/usr/lib/ruby/1.9.2/csv.rb:1340:in `open' Same code two different irb's My csv file has this in it: John,Smith,john(a)smith.com,1234567 John,Smith,john(a)smith.com,1234567 John,Smith,john(a)smith.com,1234567 Can someone point out to me what I am doing wrong?

error location
by Joel Reymont 07 Jan '11

07 Jan '11

I would like to edit MacRuby code in a Cocoa text window, press a button to "compile" it and display error information in a status line. I would also like to highlight the position of the error in my text window. How do I programmatically grab the error location from an evaluation or compilation error?

substantial benefits to x86-64
by Joel Reymont 07 Jan '11

07 Jan '11

Are there substantial benefits to running the 64-bit version of MacRuby? For example, does LLVM JIT work better on x86-64? Thanks, Joel --- http://wagerlabs.com | @wagerlabs | http://www.linkedin.com/in/joelreymont

NSPredicate crash
by Alan Skipp 06 Jan '11

06 Jan '11

Hi everyone, Has anyone had any trouble with NSPredicate causing occasional crashes when used with NSArrayController? Well actually about 50% of the time. What I have is a subclass of NSArrayController which is a data source for an NSTableView that accepts drag and drop operations. In 'awakeFromNib' a NSPredicate is defined, sometimes the error is just, “EXC_BAD_ACCESS”, other times there's a bit more info: data_source.rb:20:in `awakeFromNib': NSInvalidArgumentException: Unable to parse the format string "AND" (RuntimeError) This is the offending line: @filter_predicate = NSPredicate.predicateWithFormat("file_type == 'NSFileTypeRegular'") The crash doesn't always occur, when it doesn't my app works without any problems. I've tried the predicate in macirb and the crash doesn't occur!? Best regards, Alan

concurrent calling into macruby
by Joel Reymont 06 Jan '11

06 Jan '11

I have a plugin that's supposed to call into MacRuby to deliver stock prices. This may happen a few times per second. I will be running other MacRuby code at the same time. Think a trading systems development environment, with charting, Ruby code editing, etc. Will MacRuby be able to handle this situation?
