Embedded libraries not loading
by Darrin Eden 15 Feb '10

15 Feb '10

Hi, It appears requiring libraries and embedding aren't behaving well together. I built MacRuby r3528 this morning. 1) In Xcode start a new MacRuby application. Build, compile, embed, and then move /Library/Frameworks/MacRuby.framework out of the way. The app runs without a problem. 2) Move MacRuby.framework back into place and add "require 'time'" to rb_main.rb. Build, compile, embed, and move /Library/Frameworks/MacRuby.framework out the way. The results are "no such file to load -- time". 3) Move /Library/Frameworks/MacRuby.framework back into place and it runs again. Thanks, -- Darrin

[MacRuby] #579: i386 compilation doesn't work

#579: i386 compilation doesn't work --------------------------------+------------------------------------------- Reporter: carlo@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: --------------------------------+------------------------------------------- This bug report references MR0.5b2 as well as its standard MacRuby application template. Trying to build self-contained compiled i386 apps (embedded MR) works fine, but the apps won't run. i86_64 builds are showing no problems and work as expected, but i386 versions exit right away, logging the following error message: {{{ core:in `each': no such file to load -- bootstrap (LoadError) from [project path]/build/Release/MyApp.app/Contents/Resources/rb_main.rb:in `<main>' }}} "bootstrap" being whatever *.rbo file is to be loaded first. $LOAD_PATH looks okay, i.e. it's identical when running i386 or x86_64 code. The behaviour is the same on both single-arch builds and 32/64bit "combo" builds. Not compiling the the application yields an app which works a-okay on both architectures. Tried on a 2006 2GHz Core Duo MacBook as well as a late 2009 C2D iMac, both running XCode 3.2.1 on 10.6.2. (Both being *my* machines makes it possible I've somehow managed to misconfigure them in the same way, of course.) -- Ticket URL: <http://www.macruby.org/trac/ticket/579> MacRuby <http://macruby.org/>

NSSet and Set broken in MacRuby 0.5 final?
by Frank Illenberger 13 Feb '10

13 Feb '10

Hi there, today I updated my MacRuby installation from MacRuby 0.5b1 to 0.5 final. Sadly, this broke my class "MERStandard" which used a Set. My Cocoa app embeds the MacRuby.framework. I initialized an empty set like this, which worked fine with MacRuby 0.5b1 mySet = Set.new With MacRuby 0.5 final I am getting the following error: An exception occured: NameError uninitialized constant MERStandard::Set If I put a require 'set' at the top of my class file, I get the following error: An exception occured: LoadError no such file to load -- set Am I doing something wrong or was anything substantial changed in the relase version? Thanks and cheers Frank

Feedback: Dispatch high-level wrappers
by Ernest N. Prabhakar, Ph.D. 12 Feb '10

12 Feb '10

Hi all, As hopefully you all know, MacRuby 0.5 includes wrappers for almost all of the C "dispatch" APIs for Grand Central Dispatch. While relatively straightforward to use, the APIs are somewhat verbose and C-ish. http://svn.macosforge.org/repository/ruby/MacRuby/trunk/spec/macruby/core/g… For MacRuby 0.6, I'd like to provide higher-level convenience APIs to reduce the "cognitive overhead" and "semantic noise" of using Grand Central Dispatch. In other words, let people do what they want without having to learn or type as much as they do now. My first attempt at this is a new 'dispatch' library: http://svn.macosforge.org/repository/ruby/MacRuby/trunk/lib/dispatch/ which (from the latest MacRuby nightly) you can access via: require 'dispatch' This defines: - A Dispatch::Actor class which wraps a given object with serialization and asynchronous callbacks http://svn.macosforge.org/repository/ruby/MacRuby/trunk/lib/dispatch/actor.… - Convenience methods on the Dispatch module http://svn.macosforge.org/repository/ruby/MacRuby/trunk/lib/dispatch/dispat… - Parallel extensions to Enumerable http://svn.macosforge.org/repository/ruby/MacRuby/trunk/lib/dispatch/enumer… - A Futures class for delayed execution (duck-typed to lambda) http://svn.macosforge.org/repository/ruby/MacRuby/trunk/lib/dispatch/future… - a 'stride' function on top of Dispatch::Queue#apply http://svn.macosforge.org/repository/ruby/MacRuby/trunk/lib/dispatch/queue.… - Queue-based source constructors http://svn.macosforge.org/repository/ruby/MacRuby/trunk/lib/dispatch/queue_… I've also written up specs to both test and demonstrate these constructs: http://svn.macosforge.org/repository/ruby/MacRuby/trunk/spec/macruby/librar… These are *extremely* preliminary, and lacking in both polish and documentation. They may not be entirely correct, or even the appropriate abstractions to release as public API. However, I wanted to get something out there to provoke feedback, so we can iterate together. Hopefully we can also use this thread to start learning how to explain both the concepts and the API, as it evolves. So, feedback away! - Ernie P.

[MacRuby] #318: enable arbitrary properties in hotcocoa app Info.plist

#318: enable arbitrary properties in hotcocoa app Info.plist -----------------------------------+---------------------------------------- Reporter: isaackearse@… | Owner: lsansonetti@… Type: enhancement | Status: new Priority: minor | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: hotcocoa -----------------------------------+---------------------------------------- This patch enables adding extra key/string properties to the Info.plist for a hotcocoa application. All you need to do is add a properties hash to config/build.yml and the application builder will take the properties in the hash and append them to the applications Info.plist. The use case I had for this was that I wanted to run my app as an agent application. (no dock icon or top left menu). To do this I needed to add the key LSUIElement with a string value of "1" to the Info.plist Cheers, Isaac -- Ticket URL: <http://www.macruby.org/trac/ticket/318> MacRuby <http://macruby.org/>
