How do I subclass Obj-C classes in MacRuby?
by Terry Moore 07 May '10

07 May '10

This is only true if you follow objc init I think... for example... I came across this problem with NSWindowController and it took me a while to figure out. class PasswordController < NSWindowController def initialize initWithWindowNibName("Password") ##FAIL Never called! init called instead end class PrefController < NSWindowController def initialize(owner) @owner = owner initWithWindowNibName("Preferences") end end The first example fails and so I finally got that I needed the init method to make the window appear but I couldn't figure out why the second option worked. Must have been a long day but clearly if designate an initialize with a param init is bypased... so if I take the class A <String def initialize(b) super end end example and do A.new("hi there") gives initialize => "hi there" so what is going on? I think there might need to be some clarity..... Terry

How to set up and retrieve returned buffer from CTFrameGetLineOrigins?
by Paul Howson 07 May '10

07 May '10

I need some help with this example which arises at the boundary between MacRuby and the C Core Text framework. Consider the following Core Text function definition: void CTFrameGetLineOrigins( CTFrameRef frame, CFRange range, CGPoint origins[] ) The third argument is defined as: "origins The buffer to which the origins are copied. The buffer must have at least as many elements as specified by range's length." Clearly origins is a buffer and a series of CGPoint structures are copied into it. How can this be handled in MacRuby? Specifically: 1. What kind of argument should be passed? Presumably something constructed using the Pointer.new_with_type() function? Documentation on this function is very hard to find. 2. How to access the individual CGPoints in the returned buffer? This is not an Objective-C / MacRuby array object. It is just an address to a buffer. Easy to do in C, but how to do in MacRuby? ---------------------------------------------------------------- Paul Howson Warwick Qld Australia

I'd rather be doing it in a more Ruby-ish way though... :) Is the fact that the Ruby-standard initialize method is not called for Ruby classes descended from Obj-C classes expected? To me, at least, it violates the principle of least surprise... for example, in ruby 1.9.1 we see initialize being called russm@worcestershire:~$ irb1.9.1 irb(main):001:0> class C2 < String irb(main):002:1> attr_accessor :foo irb(main):003:1> def initialize foo = "default2" irb(main):004:2> @foo = foo irb(main):005:2> STDERR.puts "setting #{foo}" irb(main):006:2> end irb(main):007:1> end => nil irb(main):008:0> c2 = C2.new setting default2 => "" irb(main):009:0> but not in macruby 0.6 russm@alcazar:~$ macirb irb(main):001:0> class C2 < String irb(main):002:1> attr_accessor :foo irb(main):003:1> def initialize foo = "default2" irb(main):004:2> @foo = foo irb(main):005:2> STDERR.puts "setting #{foo}" irb(main):006:2> end irb(main):007:1> end => nil irb(main):008:0> c2 = C2.new => "" irb(main):009:0>

[MacRuby] #692: Embedded MacRuby still tries to use ruby library from /Library/Frameworks

#692: Embedded MacRuby still tries to use ruby library from /Library/Frameworks --------------------------------+------------------------------------------- Reporter: mike@… | Owner: lsansonetti@… Type: defect | Status: new Priority: minor | Milestone: Component: MacRuby | Keywords: --------------------------------+------------------------------------------- I have embedded MacRuby in my app using the macruby_deploy script, but it still tries to load library files from /Library/Frameworks. In the case of C extensions, this actually caused libmacruby.dylib to be loaded twice, which is bad. I worked around this by changing the RUBY_LIB before initializing MacRuby. Shouldn't MacRuby set up it's path relative to the framework from which it is loaded? -- Ticket URL: <http://www.macruby.org/trac/ticket/692> MacRuby <http://macruby.org/>
