[MacRuby] #704: Singleton bug with define_method

#704: Singleton bug with define_method --------------------------------+------------------------------------------- Reporter: mike@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: --------------------------------+------------------------------------------- I'm trying to dynamically add methods to my class in MacRuby. I'm getting a crash in my program. I haven't been able to cut that down to a smaller example yet, but I did find this problem when I tried. The following program should print this output (and does from Ruby 1.9): {{{ 10.0 Float {"foo"=>10.0} }}} With MacRuby, it prints {{{ NilClass {"foo"=>10.0} }}} If you uncomment the print statement, it starts working. Here's the code {{{ class SingletonTest attr_reader :values def initialize @values = {} end def addMethod(name) singleton = class << self self end singleton.instance_exec(name) do |name| define_method("#{name}=") do |value| @values[name] = value end define_method("#{name}") do # puts "returning value" return @values[name] end end end end singleton_test = SingletonTest.new() singleton_test.addMethod('foo') singleton_test.foo = 10.0 value = singleton_test.foo puts value puts value.class puts singleton_test.values }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/704> MacRuby <http://macruby.org/>

MacRuby and LLVM 2.7

Hi, The LLVM release notes say that MacRuby v0.6 will work with 2.7 (http://llvm.org/releases/2.7/docs/ReleaseNotes.html) but I'm having trouble with it: """ $ rake (in /Users/mbolingbroke/Programming/Checkouts/MacRuby-0.6) /usr/bin/ruby tool/compile_prelude.rb prelude.rb miniprelude.c.new rm miniprelude.c.new /usr/bin/g++-4.2 -I/usr/local/include -D_DEBUG -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS -O2 -fno-rtti -fno-common -Woverloaded-virtual -I. -I./include -g -Wall -arch i386 -arch x86_64 -Wno-parentheses -Wno-deprecated-declarations -Werror -I./icu-1060 -c main.cpp -o main.o In file included from main.cpp:8: llvm.h:12:33: error: llvm/ModuleProvider.h: No such file or directory In file included from main.cpp:17: vm.h:602: error: ISO C++ forbids declaration of ‘ExistingModuleProvider’ with no type vm.h:602: error: expected ‘;’ before ‘*’ token In file included from main.cpp:8: llvm.h:12:33: error: llvm/ModuleProvider.h: No such file or directory In file included from main.cpp:17: vm.h:602: error: ISO C++ forbids declaration of ‘ExistingModuleProvider’ with no type vm.h:602: error: expected ‘;’ before ‘*’ token lipo: can't figure out the architecture type of: /var/folders/4j/4jTZECFrFIyDlJjF8ivIeE+++TI/-Tmp-//ccJH4WrV.out rake aborted!

NSObject.to_s question
by Jordan Breeding 08 May '10

08 May '10

Right now for custom objects on the Objective-C side even if you provide a -[Object description] call to_s will fall through and hit to_s from NSObject which right now just has the class name and pointer. Is it already planned for the future to use the description method in to_s on the MacRuby side? Should I file a bug report? Jordan
