[Anne G <an...@wj...>]

Ahah! wonderful. Thank you so much. I had indeed called the
folder rubyprojects/addon  and I understand now how that is
a problem. I had not debugged the problem all the way. Thank
you so much for finding what the problem was!

thanks you

Anne

Ahah! The problem is that your directory name contains a ':'  
character (in the Finder it'll show up as a forward slash '/'). The  
path to the Resources directory is added to $LOAD_PATH, which is  
eventually converted to a :-separated string in the ruby core.  
Therefore, the full path to your application is lost.

You could perhaps report this as a bug in ruby.

The temporary fix is to remove that character from the directory name :)

Re: [Rubycocoa-talk] Re: installing rubycocoa on tiger

[Anne G <an...@wj...>]

For both  the tutorial and simpleapp I do the same thing.
All the code comes in a folder. I double click on the
simpleapp.pbproj which opens xcode. (it tells me the project
was saved with an older version of xcode, and it creates
simpleapp.xcodeproj. then I click on build and run.

simpleapp runs fine from the developer/example/rubycocoa
folder, but it does not run from the desktop folder.

the error message shows up in its own xcode window.

thanks for your help

Could you explain exactly how you are attempting to run the program?

Using 'ruby rb_main.rb' will not work - you have to start the  
compiled stub program in the Contents/MacOS directory or open the  
application as you would any other (from the Finder or use the 'open'  
command).

Running *any* Cocoa program would have shown the SIMBL error  
messages. Look in your console.log file and you'll probably see lots  
of them, corresponding to each program you run.

[Rubycocoa-talk] [PATCH] allocWithZone fix

[Jonathan P. <jp...@dc...>]

Hello,

This patch came up in a discussion a few weeks ago but hasn't been  
merged yet as far as I can tell.

class_createInstanceFromZone can't take a NULL zone argument - so  
it's necessary to look up NSDefaultMallocZone() manually.

Cheers,
Jonathan

[Rubycocoa-talk] [PATCH] Fix for ns_override of methods returning large values

[Jonathan P. <jp...@dc...>]

Hello,

When using ns_overrides on methods that return large values (e.g., an  
NSRect), a crash occurs since the native function implementation used  
doesn't handle the msgSend_stret hidden first argument.

The attached patch resolves this issue by choosing between one of two  
implementations for the handle_ruby_method function.

I haven't adjusted indentation in order to make the patch smaller and  
clearer, so some cleanup may be required after application.

Cheers,
Jonathan

Re: [Rubycocoa-talk] Re: installing rubycocoa on tiger

[Anne G <an...@wj...>]

Actually the simbl error was not the reason the rubycocoa
tutorial does not run.

I replaced the tutorial rb_main.rb with the simple
example rb_main.rb since they seemed to do the same
thing and I know simple example works.
after rbfiles each do...
I added some debugging puts
   	puts File.basename(path)
        require( File.basename(path) )
	puts "this is ok "
Controller.rb
/Users/anne/Desktop/learning ruby/ruby
projects:addon/Code/build/Development/RubyCocoaTar.app/Contents/Resources/rb_main.rb:17:in
`require': No such file to load -- Controller.rb (LoadError)
This require must be the problem since it does not print
the "this is ok"

whereas simple applications gives
AppController.rb
this is ok
MyView.rb
this is ok

It looks like the code looks in the project and
finds .rb file. In the tutorial project there is just one
file, Controller, I wonder why it did not find it to load.
"no such file to load"

I wondered if it was a path problem, so I copied simple
application to the same folder that has the tutorial
project.

SimpleApp has exited with status 1.
AppController.rb
/Users/anne/Desktop/learning ruby/ruby
projects:addon/simpleapp/build/Development/SimpleApp.app/Contents/Resources/rb_main.rb:13:in
`require': No such file to load -- AppController.rb
(LoadError)

same error as with tutorial.

What is the problem? What do I need to do to run rubycocoa
from anywhere. I just installed
/Installed/\ Done/RubyCocoa-0.4.2-tiger.dmg
I did not see anything about setting a path.

Re: [Rubycocoa-talk] Re: installing rubycocoa on tiger[MESSAGE NOT SCANNED]

[Anne G <an...@wj...>]

Yes, it is true, there was two simbl directories, one with
an acidsearch bundle. I deleted both of them, and the
rubycocoa regarding simbl disappeared. I don't quite
understand why runny rubycocoa would start something than
the program to run,  but for now, problem solved.

thank you for your patience with me

Did you find out what you have got installed that requires SIMBL?

Try moving the directory "SIMBL" in /Library/InputManagers to the  
trash and trying again.

The second error you're seeing (about NSView not being correctly  
initialised) is something to do with RubyCocoa, but it's not yet been  
resolved. Things seem to work okay despite the error message.

[Rubycocoa-talk] Re: installing rubycocoa on tiger

[Anne G <an...@wj...>]

Hi

I have been wondering about my simbl problem.

I tried to run simple application. The application does run
fine.

But I get the following messages:

2005-12-19 18:44:42.170 SimpleApp[557] Can't open input
server /Library/InputManagers/SIMBL
2005-12-19 18:44:42.447 SimpleApp[557] MyView(0x3fbe60) -
NSView not correctly initialized. Did you forget to call
super?

Simple application is in developer/examples/rubycocoa

With all the examples, I can see how rubycocoa works, but
it would be nice to have examples which run without errors

I think there is a bug. Specifically, rbnum_to_nsnum from  
ocdata_conv.m should return an autoreleased object:

static BOOL rbnum_to_nsnum(VALUE rbval, id* nsval)
{
   BOOL result;
   VALUE rbstr = rb_obj_as_string(rbval);
   id pool = [[NSAutoreleasePool alloc] init];

   *nsval = [[NSDecimalNumber alloc] initWithString: nsstr];
   result = [(*nsval) isKindOfClass: [NSDecimalNumber class]];
   [pool release];
   return result; // **** should be return [result autorelease];
}

[Rubycocoa-talk] Return values leak memory

[Frank I. <ill...@ma...>]

Hi,

I just checked my RubyCocoa app for memory leaks with the 'leaks'  
command line tool. I observed lots of leaks that seem to come from  
the conversion of ruby numbers to NSNumbers. The stack trace of the  
leak always shows the following:

                 -[NSObject(NSKeyValueCoding) valueForKeyPath:]
                  _NSGetUsingKeyValueGetter
                  imp_valueForUndefinedKey
                  _objc_msgForward
                  -[NSObject(NSForwardInvocation) forward::]
                  imp_forwardInvocation
                  -[RBObject forwardInvocation:]
                  -[RBObject rbobjForwardInvocation:]
                  -[RBObject stuffForwardResult:to:]
                  rbobj_to_nsobj
                  rbobj_convert_to_nsobj
                  rbnum_to_nsnum
                  -[NSDecimalNumberPlaceholder initWithString:locale:]
                  -[NSDecimalNumberPlaceholder initWithDecimal:]
                  NSAllocateObject
                  _internal_class_createInstanceFromZone


It looks like the objects returned from rbobj_to_nsobj never get  
released. Is this a bug of RubyCocoa or am I doing something wrong?

I don't think that's to do with RubyCocoa. Sounds like you've got  
some application enhancement software installed that uses the SIMBL  
plugin manager [1]. Perhaps something is going wrong with whatever  
thing is installed?

Sorry, that should read @data.size - 1, I missed one rename when I

[Rubycocoa-talk] installing rubycocoa on tiger

[Anne G <an...@wj...>]

Hi

I am running tiger 10.4.3 with the ruby 1.8.3 which comes
with it.

I downloaded the binary package for tiger
RubyCocoa-0.4.2-tiger.dmg and it seemed to install fine. I
tried to run the rubycocoa tutorial (as downloaded from the
end of the tutorial) from
http://www.macdevcenter.com/pub/a/mac/2004/10/12/cocoa.html?page=3

This tutorial used to run on the rubycocoa binary for
panther. It now gives me an error message
Can't open input server /Library/InputManagers/SIMBL

Is that a problem with this program no longer running on
rubycocoa or is it a problem with my installation of
rubycocoa?

thanks for your help

I don't see anywhere in your code where you add a new row to the  
NSTableView. The error you're seeing occurs because the row being  
asked for doesn't exist.

Is your NSTableView populated using a datasource or bindings?

With a datasource, I think you may have to add a prototype element to  
the datasource and call tableView.reloadData. After that, you can  
hopefully select the new row.

With bindings, you add a new row by going through the NSTableView's  
NSArrayController (you can bind insert: directly to a button's action).

Can you give an example of the PyObjC code that works?

Cheers,
Jonathan
