[Rubycocoa-talk] bridging between ruby and objective-C

[S. W. <sbw...@ya...>]

I want to call back and forth between Ruby and ObjC objects, I've
figured it out in a basic way and posted it here:

http://simonwoodside.com/weblog/2009/2/10/wondeful_joy_mix_ruby_and/

However, it would be nice if on the ObjC side I could actually declare
objects of a type defined on the Ruby side instead of using "id"...
and have the compiler, or at least just the linker understand that.
Does anyone know if it's possible?

[Rubycocoa-talk] Request for proposals for the first Ruby+Cocoa only conference.

[Eloy D. <elo...@gm...>]

Hi,

As some of you might already know, we are organizing a Ruby and Cocoa  
only conference in may in Amsterdam.
This email is purely meant as a request for proposals, so we can work  
on the schedule.
Once we have the details we will post an elaborate article about it on  
our blog.

So please send your proposals or questions to me, or ping me (alloy)  
on IRC; #ruby-osx on freenode.
The available time slots for talks range from 10 mins. to 45 mins.

Cheers,
Eloy

Hahaha, I'll try to make them at least 2 lines next time ;-)

No worries :-)

The bad news is that no, there isn't any documentation.  Not in the  
sense of a book, or tutorials or that sort of thing.  At least, not  
that I'm aware of.

The good news is that there are lots of good examples of RubyCocoa  
code for implemnting the projects in the Hillegass book.  They are  
already on your hard drive, in /Developer/Examples/RubyCocoa  That's  
how I figured out this problem.  By the time you've run through the  
whole Hillegass book, you'll have found most of the gotchas - I  
haven't run into any new ones since finishing the book.

If you've tried that and it didn't give you your answer, then of  
course, you can just ask here - you've probably noticed that we don't  
have a lot of traffic on the list, so you don't have to worry about  
people getting snarky.  Plus, everyione here is very friendly - except  
Eloy, who can't help pointing out that the long convoluted solutions  
that I suggest can be replaced by one line of code - very  
embarassing! :-)

Anyway, I don't think the doc situation is ever going to improve, as  
we're all pretty much just hanging around waiting for MacRuby to  
arrive in an official OS X release.  But honestly, I haven't really  
felt that we need any...

Anyway, I'm glad I was able to help :-)

Re: [Rubycocoa-talk] Possible bug in key-value handling in RubyCocoa

[Steven D. A. <st...@ne...>]

Hey Brian, what you are reading is the place where Hillegass attempt  
to describe how to implement undo for edits.  For example, if I type  
in "When in the course of human events" in a text field, if I hit  
undo, that text should be removed.

The kind of undoing that I implemented is the kind that goes right up  
to page 145, which is where I got stuck.  In that undo, we merely  
manage the @employees array, that is, remove the most recent addition  
if undo is selected.  For that kind of undoing, startObservingObject  
is not required.

Alli's very helpful suggestion was to look at the kvc_array_accessor  
method as a way to inform RubyCocoa that we are employing key-value  
bonding on a particular element.  This is not necessary in ObjC,  
therefore Hillegass didn't discuss it.  Note that Brian Marick's book,  
RubyCocoa, which is still in beta on the Pragmatic Programmer's  
website, does discuss the issue to some degree.

Hey Alli, that did it!  Thanks so much for the help.  Is there any  
documentation for these kinds of functions (e.g. are there more  
besides the ones you mentioned)?

Thanks again, that works great, I am back on track. :-)

Re: [Rubycocoa-talk] Possible bug in key-value handling in RubyCocoa

[Brian M. <ma...@ex...>]

I'm confused by the Objective-C version. It doesn't have the  
MyDocument.m method startObservingPerson (on p. 146 of Hillegass). It  
shouldn't work without setting up observing. (I can't check - won't  
build in my older version of Xcode.)

Am I looking at the wrong pages?

Re: [Rubycocoa-talk] followup on undo issues

[Allison N. <dem...@ma...>]

Steven,

Are you aware of kvc_accessor and kvc_array_accessor?

For example, at the start of a class definition, when I have a class  
attribute that I want to be accessed by key value coding, I put:

class Database < NSObject
   attr_accessor :last_update, :appartements, :arrondisements
   kvc_array_accessor :appartements, :arrondisements

Note that the attr_accessors are necessary because I also access these  
values through normal ruby programming.

kvc_array_accessor is used when the attribute to be accessed is an  
array, and kvc_accessor is used when it's just a normal attribute that  
you are accessing.

I know that I got bitten by this when doing raiseman.

Hope that helps,

Alli

Re: [Rubycocoa-talk] followup on undo issues

[Eloy D. <elo...@gm...>]

No need to copy over the NIB, you should have a functioning one in XIB  
from your objc test.
About the undefined symbol, have you added the RubyCocoa.framework to  
your project and linking to it?

When I try to do that, I run into a number of problems.  First of all,  
the ObjC project uses XIB files rather than NIB files.  The Ruby  
program uses NIB files.  I am not familiar with XIB files; I assume  
they are something new similar to a NIB.

Second, when I try to copy the NIB files to the ObjC project, it  
doesn't work.  The files do not appear in the Resources section, which  
is where I dropped them, and where they are located in the RubyCocoa  
project as well.

When I try to run the project even though the NIB files are not  
present, I get this error:

/Users/thoth/Source/learning/raiseman-objc/build/Debug/raiseman- 
objc.app/Contents/MacOS/raiseman-objc
Undefined symbols:
   "_RBApplicationMain", referenced from:
       _main in main.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
	  "_RBApplicationMain", referenced from:
	      _main in main.o
	ld: symbol(s) not found
	collect2: ld returned 1 exit status

main.m looks like this:

#import <Cocoa/Cocoa.h>
#import <RubyCocoa/RBRuntime.h>

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

Any thoughts?

Re: [Rubycocoa-talk] followup on undo issues

[Eloy D. <elo...@gm...>]

Hi Steven,

Could you try copying over your source files to the Objective-C version
you wrote to see if the problem might have been the xcode template  
that was used?
I seem to remember some problem around this.

[Rubycocoa-talk] followup on undo issues

[Steven A. <st...@ar...>]

I tried reimplementing the same raiseman program in Objective-C, per  
the book, and that worked fine.  This suggests there's a bug in the  
RubyCocoa handling of key-value invocation.  Furthermore, I upgraded  
to the latest version of RubyCocoa for the test (version 0.13.2) and I  
am using Ruby 1.8.6.

The working Objective-C file is available upon request, as is the non- 
working RubyCocoa version.

[Rubycocoa-talk] Possible bug in key-value handling in RubyCocoa

[Steven D. A. <st...@ne...>]

Following up on my previous post related to the "raiseman" application  
covered in Aaron Hillegass's Cocoa Programming for Mac OS X.....  I  
implemented the same program in Objective-C, an identical analogue to  
the program in Ruby, and it works fine in Objective-C.  That is, the  
expected methods to insert and remove "employee" objects (see below)  
are called in Obj-C but not RubyCocoa.  That tells me there is a bug  
in the RubyCocoa interface that prevents key-value coding from working  
properly.....or possibly I am missing some detail in my implementation  
of the RubyCocoa program.  The Objective-C project which works fine is  
attached.  Run the program, and then add several records and undo them  
by typing command-Z (or selecting undo from the Edit menu).  If you do  
this, the key-value coding will work fine, that is, the following  
methods will be called to undo and redo:

- (void)insertObject:(Person *)p inEmployeesAtIndex:(int)idx
- (void)removeObjectFromEmployeesAtIndex:(int)idx

The equivalent methods in the Ruby implementation are not called:

	def insertObject_inEmployeesAtIndex(p, index)
	def removeObjectFromEmployeesAtIndex(index)

I have also tried these Ruby methods with a trailing _ just to be sure  
that's not the problem.  It didn't change the result.

[Rubycocoa-talk] problems implementing undo in raiseman sample application

[Steven A. <st...@ar...>]

Hello, I am working through the book Cocoa Programming for Mac OS X by  
Aaron Hillegass using RubyCocoa rather than Objective-C, and I am at  
the section where we are attempting to implement undo for the add new  
employee and delete new employee buttons.

My controller object as an @employees array as a member value.  Given  
this name, I have implemented, in my controller, the functions:

     insertObject_inEmployeesAtIndex(p, idx), and
     removeObjctFromEmployeesAtIndex(idx)

According to the book, "[...] these methods will be called  
automatically when the NSArrayController wishes ro insert or remove  
messages."  However, my functions do not seem to be getting called.  I  
have put NSLog statements to see whether they are being called, but  
right now it appears not.

My project is packaged below.  If you have any idea what I might be  
doing wrong, please let me know!

Are you sure that somestring is actually a string?

Your code works fine OMM.

You can also use this.

 >> 'this is a string'.scan(/./)
=> ["t", "h", "i", "s", " ", "i", "s", " ", "a", " ", "s", "t", "r",  
"i", "n", "g"]

[Rubycocoa-talk] Ruby String Split Method

[Harry M. <har...@go...>]

Sorry if this is an obvious or stupid question, but I have been trying for
some time to find a way of splitting a string into an array so that each
character is a member of the array.

I initially tried using ruby's somearray = somestring.split(//), but I got
an error saying:

NoMethodError: undefined method `empty?' for //:Regexp

/Library/Frameworks/RubyCocoa.framework/Resources/ruby/osx/objc/oc_attachments.rb:839:in
`split'

I then tried a Cocoa approach with the componentsSeparatedByCharactersInSet but
it gave me an error also.

Am I missing an obvious method of splitting a string into an array?

[Rubycocoa-talk] [ANN] SecureRequire

[Rolando A. <fun...@gm...>]

Hello all again, I think some of you might be interested:

I've developed a small ruby extension, specifically designed for  
RubyCocoa (although it can work with plain ruby scripts) that lets you  
keep your code encrypted inside the application bundle.
The decryption scheme is obscured, so it's not as easy as running  
openssl from the command line to decrypt the code, and also the  
decryption is made in memory, so no temporary file exposing your code  
is created.

More info:

http://www.rolando.cl/2009/01/securerequire-require-encripted-ruby.html

Expect a full release during the next week.
Regards,

I all else fails, you can always create one by hand.
See one of the many bridgesupport files in the standard frameworks.

Re: [Rubycocoa-talk] Generating bridge metadata without Framework

[Allison N. <dem...@ma...>]

 Hi Brian,

Maybe I've misunderstood your question, but here's my understanding of things:

If you are writing you're own .m file, you just make sure that it is all encapsulated in an Objective-C class, rather than using standard C.  The RubyCocoa bridge then handles the objective-C class automatically.

I don't know if I'm telling you something you already know, but if you have an Objective-C class, you just add its source files (.m/.h) to your RubyCocoa project, and XCode compiles them automatically for you, and you can access them from Ruby the same way you access any Cocoa classes.

Hope that helps,

Alli

[Rubycocoa-talk] Generating bridge metadata without Framework

[Brian M. <ma...@ex...>]

I have a tiny .m file that I use for testing. I create a bundle from it:

     `cc -o #{basename}.bundle -bundle -framework Foundation  
#{basename}.m`

Is there a way to get metadata for that file without building a  
framework? gen_bridge_metadata(1) has an example of creating metadata  
from -lcurl, but I can't make it work for my .m and .h file. Should I  
keep digging or give up?
