Re: [MacRuby-devel] objective-c runtime
by Garett Shulman 06 Jan '11

I'm guessing this is documented somewhere but have not been able to find it yet... How can objective C runtime methods such as class_copyMethodList be called from MacRuby? Thanks! -Garett

Re: [MacRuby-devel] CoreAudio frameworks
by Garett Shulman 06 Jan '11

06 Jan '11

Hello, is it possible to use CoreAudio frameworks from MacRuby? I am trying the following simple experiment: irb(main):001:0> framework 'AudioUnit' => true irb(main):002:0> load_bridge_support_file 'AudioUnit.bridgesupport' => main irb(main):003:0> AudioComponentFindNext(nil, [KAudioUnitType_Generator]) TypeError: unrecognized runtime type `{AudioComponentDescription=IIIII}' I create the bridgesupport file with: gen_bridge_metadata --64-bit -f AudioUnit -o AudioUnit.bridgesupport However, I do not see any struct definitions in the generated bridgesupport file. If anyone has thoughts about documentation resources which may be illuminating or any other insights or suggestions they would be greatly appreciated. Thanks! -Garett

obj.method(m) often gives a TypeError
by Tim Rand 06 Jan '11

06 Jan '11

I noticed that obj.method(m) is often giving an error. The error given on [].methods looks like: Tim:~/Desktop> macirb >> def err(obj) >> obj.methods(1,1).each do |m| ?> begin ?> obj.method(m) >> rescue => e >> p e >> end >> end >> end => nil >> err([]) #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `?'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `{_NSRange=QQ}'> #<TypeError: unrecognized runtime type `?'> No errors are raised with the same code (without parameters on the methods of course) in ruby 1.9.1.

Using an SQLite wrapper with macruby
by Ruben Fonseca 05 Jan '11

05 Jan '11

Hi all. I'm trying to build a MacRuby 0.8 app with XCode. I want to interact with an exisitng Sqlite3 database. Since I don't want to package or mess with any Rubygem, I decided to look into existing Objective-C Sqlite wrappers. I've tried PLDatabase and fmdb, and failed with both. The code compiles and the application runs, but when calling a C function what accepts a va_arg argument list, my app receives a EXC_BAD_INSTRUCTION. Example: Objective-C function interface: - (FMResultSet *)executeQuery:(NSString*)sql, ... { Ruby code db.executeQuery "SELECT * FROM call" it receives the error on this C line inside the executeQuery function va_start(args, sql); Any hints? Do you recommend a simple way of interacting with a Sqlite3 app with macruby + xcode, without using any gems? Thank you Ruben

Place to file bug report for website?
by Buddy Lindsey, Jr. 05 Jan '11

05 Jan '11

Is there a place to file a bug report for the MacRuby.org website if we find something wrong? I was looking at this page: http://www.macruby.org/recipes/tdd-in-objective-c-with-macruby.html And at the top it still says current version 0.7.1. Thought i'd let someone know. --- Buddy Lindsey http://www.buddylindsey.com http://www.twitter.com/buddylindsey

Hotcocoa or not?
by Buddy Lindsey, Jr. 03 Jan '11

03 Jan '11

All, I am just starting with MacRuby and am kind of confused. There seems to be 2 ways to do GUI development. Hotcocoa or Pure Cocoa API. My confusion is on which one is best I like hotcocoa because it seems fairly straight forward on doing GUI stuff, the little I have looked at it, but seems to rely on Cocoa API where there aren't any mappings. However, I can use interface builder and xcode more easily going with the pure cocoa api. I also am very confused when doing anything with interface builder so I am leaning toward hotcocoa. As a note on my background. I just got my first mac in July and started doing anything with ruby [on rails] in August. I come from a web development background so desktop apps are a bit new to me. Anyone have any advice, comments, and or words of wisdom all they way around? My goals is to make a fairly simple app I can put into the AppStore.
