rubycocoa-talk — talking about RubyCocoa

[Rubycocoa-talk] SVN repository flaky for anyone else?

[Jon B. <jo...@gm...>]

Hi, for past 2 weeks or so its been a little hard to get to updates  
from trunk ...

[MacBook-Pro:~/WORKAREA/SVN_HOME/rubycocoa]$ svn up
svn: PROPFIND request failed on '/svnroot/rubycocoa/trunk/src'
svn: PROPFIND of '/svnroot/rubycocoa/trunk/src': Could not resolve  
hostname `svn.sourceforge.net': No address associated with nodename  
(https://svn.sourceforge.net)
[MacBook-Pro:~/WORKAREA/SVN_HOME/rubycocoa]$ ping svn.sourceforge.net
ping: cannot resolve svn.sourceforge.net: Unknown host

Just wondering, anyone else w/ similar issues?

Re: [Rubycocoa-talk] packaging ruby within an RC app

[Jon B. <jo...@gm...>]

I just "rubycocoa new TestApp", build + get this:

[MacBook-Pro:~/TestApp/build/Release/TestApp.app/Contents/MacOS]$ ./ 
TestApp --version
ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-darwin8.9.4]
[MacBook-Pro:~/TestApp/build/Release/TestApp.app/Contents/MacOS]$

I think (?) the point behind a bundled Ruby w/ your RC app is to not  
have to need the end user to touch any files or need to set anything  
and use a shipping Ruby capable of running on both PPC/Intel.

I just downloaded the one-click (http://rubyosx.rubyforge.org/) and  
extract using Pacifist to a /VM directory under my project, how can I  
get it to use that ruby instead of system ruby?

Re: [Rubycocoa-talk] packaging ruby within an RC app

[Fujimoto H. <hi...@fo...>]

YOURAPP/Contents/MacOS/YOURAPP is almost same as the ruby command.

e.g.
  $ /Applications/TMPresents.app/Contents/MacOS/TMPresents --version
  ruby 1.8.2 (2004-12-25) [universal-darwin8.0]

TMPresents.app is a RubyCocoa app.

main.m of a typical RubyCocoa app is:
  int main(int argc, const char *argv[]) {
    return RBApplicationMain("rb_main.rb", argc, argv);
  }

RBApplicationMain is a traditional API. And RBApplicationInit is an
alternative modern API:

  int main(int argc, const char *argv[]) {
    RBApplicationInit("rb_main.rb", argc, argv, nil);
    return NSApplicationMain(argc, argv);
  }

rb_main.rb:
  require 'osx/cocoa'
  OSX.init_for_bundle do |bdl, param, log|
    # param  - the 4th argument of RBApplicationInit as optional data
    # log    - nslog wrapper for this block

    # initialize/loadin your ruby programs here.
    log.info("bdl=%p, param=%p", bdl, param)
    require 'your_ruby_programs'
    ...
  end
end

[Tim P. <he...@ti...>]

rb_main.rb doesnt have a shebang line so I dont think that would  
work? Having said that if it doesnt have a shebang line how does RC  
know where the ruby bin is? Or is that somehow embedded inside the  
framework when it is built?

Re: [Rubycocoa-talk] packaging ruby within an RC app

[Jon B. <jo...@gm...>]

Not sure about this but here is my guess:

If you create a folder VM under your project and lay down all the  
files this installer provides and include the universal builds of  
your gems and then somehow modify your PATH to run only that Ruby  
executable under VM folder (im guessing this will have to occur  
within main.m), you would really get standalone app with your own  
Ruby distro.

Since you can have a file ~/.MacOSX/environment.plist I wonder if  
there might be something RC developer could add to Info.plist that  
could tweak the PATH setting?  (Or this might be something which can  
be done already?)

Like you said before this will definitely add nice bloat to your  
project but @ least you can guarantee / provide your own runtime for  
users not familiar w/ Ruby setup < 10.4.

I feel too :)

I don't have any resources to grub QCPatch design cause that is not
publicized by Apple ;)
Everything I know so far is a collection of lots of web searches and
observations of QuartzComposer behavior.It seems the QuartzComposer
framework collects all ports by their names (prefixed by input/output)
when a QCPatch instance is initialized.

Anyway, If adding/removing ports at any runtime is available by some
API, that will be enough for me. I will try digging more.

True, I also figured that. Let's keep the current behavior. Looks like

I think it might be difficult.
Because the second argument accepts a string in raw encodings like 'i@:'.

Re: [Rubycocoa-talk] publish members in Ruby class to ObjC

[Laurent S. <lsa...@ap...>]

This is unfortunately not supported yet :(

However, I don't really know QCPatch, but is it really necessary to  
provide instance variables in the superclass? This looks weird and  
unusual. Generally in superclasses you provide methods but not  
instance variables.

Do you have a pointer to the mechanism behind QCPatch and this  
instance variable stuff? I could not find on google.

Thanks,
Laurent

[Rubycocoa-talk] publish members in Ruby class to ObjC

[Motohiro T. <mo...@gm...>]

Hi,

I want to publish some member variables in Ruby class to Objective-C.
How can I do that ?

in QuartzComposer framework, member named "input***" in custom class
are automatically detected at runtime, like this:

@interface MyCustomPatch : QCPatch
{
    QCStringPort *inputFoo;
}

I wrote Ruby class like:

class MyRubyCustomPatch < OSX::QCPatch
  attr_accessor :inputFoo
 ...
end

but "inputFoo" is not detected.

I tried to wrote *.h for MyRubyCustomPatch class in Objective-C to
publish inputFoo, but it was no use...


sorry for my continuous posts. m(_ _)m

Re: [Rubycocoa-talk] return simple int from Ruby to ObjC

Right, I got correct return value !

Re: [Rubycocoa-talk] return simple int from Ruby to ObjC

[Laurent S. <lsa...@ap...>]

Oops, please try

   objc_method :getInt, ['int']

The second argument of objc_method is supposed to be an Array. I will  
fix the method to accept a String.

Re: [Rubycocoa-talk] return simple int from Ruby to ObjC

[Motohiro T. <mo...@gm...>]

Laurent:

Thanks for your quick reply.

I tried your advice, and observed strange behavior.

class Hoge < OSX::NSObject
	objc_method :getInt, 'int'
	def getInt
		5
	end
end

and when call this, NSLog shows:

2007-07-15 22:50:15.667 retval[7097] XXX returning ffi type void for
unrecognized encoding 'nt'

I'm wondering why "i" of int is lack...

Re: [Rubycocoa-talk] return simple int from Ruby to ObjC

[Laurent S. <lsa...@ap...>]

When creating a Ruby method like this, without providing its ObjC  
runtime signature, RubyCocoa will assume that all arguments and the  
return value are Objective-C objects (of the type 'id'). Because there  
is no way for RubyCocoa to know. This is why you get from the ObjC  
world an NSNumber and not an "int".

To work around this, you need to register the Ruby method into the  
ObjC runtime:

   def getInt ... end
   objc_method :getInt, 'int'

This will register getInt as a method that doesn't take any argument  
and returns a C integer.

Usually when you are overriding an ObjC method from Ruby, or  
implementing an ObjC informal protocol in Ruby, you don't need to use  
objc_method. But in this special case, it is required. Fortunately,  
most people won't need to use it.

[Rubycocoa-talk] return simple int from Ruby to ObjC

[Motohiro T. <mo...@gm...>]

Hi,

I'm wondering how to return simple "int" type value from Ruby code to
Objective-C code.
Ruby code passes Fixnum, and Objective-C code recieves NSCFNumber
instead of simple int.
Any suggestion ?


Ruby code:

  class Hoge < OSX::NSObject
    def getInt
      5
    end
  end


Objective-C code:

	Class helper = NSClassFromString(@"Hoge");
	id hoge = [[helper alloc] init];
	NSLog(@"%@ %d", [[hoge getInt] class], [(NSNumber *)[hoge getInt]
decimalValue]);


and those show:

  2007-07-15 21:52:56.954 retval[5100] NSCFNumber 8448


thanks,

We should definitely summarize this in a wiki page on the website.

We already have a page but it's empty :( If someone is willing to fill  
it :)

Re: [Rubycocoa-talk] packaging ruby within an RC app

[Tim P. <he...@ti...>]

Is it just me or does that read as if its a universal version of ruby?

Ive just tried it installing it, and it appears that it installs ruby  
in /usr/local/bin

tim-perretts-computer:/usr/local/bin timperrett$ ./ruby -v
ruby 1.8.6 (2007-03-13 patchlevel 0) [universal-darwin8.0]

Further to what we have been talking about on this list we could take  
a universial ruby distribution and put that inside our application  
couldn't we? Having said that, how would RC know to use the ruby  
within the application?

Cheers

Tim

Try this:

  objc_method :execute_time_arguments, %w|char id double id|
  def execute_time_arguments(fp8, fp12, fp20)
    ...
  end

You can see documents of RubyCocoa in your machine:

[Rubycocoa-talk] passing args from ObjC to Ruby

[Motohiro T. <mo...@gm...>]

Hi,

While writing QuartzComposer CustomPatch with RubyCocoa, I'm in
trouble with passing arguments from Objective-C code to Ruby.
How can I pass more than one arguments to Ruby code from Objective-C code ?


Objective-C code:

  - (BOOL)execute:(id)fp8 time:(double)fp12 arguments:(id)fp20 {

    Class helperClass = NSClassFromString(@"CustomRubyPatch");
    rubyobj_ = [[helperClass alloc] initWithQCPatch:self];

    [rubyobj_ execute:fp8 time:fp12 arguments:fp20];
    return YES;
  }

and Ruby code:

  def execute(fp8, time, arguments)
    @otport.setStringValue @inport.stringValue.gsub(/Objective-C/, "Ruby")

    true;
  end

when [rubyobj_ execute:...] is invoked at runtime, an exception is
raised ("selector not recognized").

thanks,

Re: [Rubycocoa-talk] ObjcPtr and NSBitmapImageRep

[Laurent S. <lsa...@ap...>]

Seems expected, since the method is declared to return a 'unsigned  
char *'. So, RubyCocoa is returning you a Ruby string. However, during  
the conversion, some data may be lost, if there is for example a 0  
byte in the middle. I think that we should change the BridgeSupport  
metadata to mark this method returning a 'void *' instead, so that  
RubyCocoa will use an ObjcPtr.

[Rubycocoa-talk] ObjcPtr and NSBitmapImageRep

[Sal S. <sal...@gm...>]

When i call bitmapData im getting a string back instead of a pointer  
as per the docs

is this a bug or am i using it wrong?

bmp =  NSBitmapImageRep.alloc.initWithData(tiff)
x = ObjcPtr.new(bmp.bitmapData)
