#709: Different behaviour when including a module into Class in MacRuby vs Ruby 1.9.2 ----------------------------------+----------------------------------------- Reporter: james@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: mocha class module include ----------------------------------+----------------------------------------- I'm seeing different behaviour when including a module into Class in MacRuby vs Ruby 1.9.2. This is a simplification of a problem I'm seeing running Mocha [1] tests in MacRuby. I seems to be specific to including the module into the Class class and not a user-defined class. It also doesn't seem to matter whether the class has already been defined or not. {{{ $ rvm macruby $ irb macruby-0.6 > module X; def x; "x"; end; end => nil macruby-0.6 > class Class; include X; end => Class macruby-0.6 > Class.new.x NoMethodError: undefined method `x' for #<Class:0x20020f960> from /Users/jamesmead/Code/mocha/(irb):3:in `<main>' }}} {{{ $ rvm 1.9.2 $ irb ruby-1.9.2-preview1 > module X; def x; "x"; end; end => nil ruby-1.9.2-preview1 > class Class; include X; end => Class ruby-1.9.2-preview1 > Class.new.x => "x" }}} {{{ $ rvm macruby $ irb macruby-0.6 > module X; def x; "x"; end; end => nil macruby-0.6 > class Y; include X; end => Y macruby-0.6 > Y.new.x => "x" }}} {{{ $ rvm macruby $ irb macruby-0.6 > module X; def x; "x"; end; end => nil macruby-0.6 > class Y; end => nil macruby-0.6 > class Y; include X; end => Y macruby-0.6 > Y.new.x => "x" }}} [1] http://github.com/floehopper/mocha/tree/macruby -- Ticket URL: <http://www.macruby.org/trac/ticket/709> MacRuby <http://macruby.org/>
