OK, i've started one of my own, this is to let you some result.

I've choosen the "NameAndAddress" example where the main.m is called =20
"NameAndAddress_main.m".

first i've tried using a "NameAndAddress_main.rb" to mimic what's in =20
the original Obj_C project then, i've changed the line :

     return RBApplicationMain("rb_main.rb", argc, argv);
to :

     return RBApplicationMain("NameAndAddress_main.rb", argc, argv);

and add a new file "NameAndAddress_main.rb" having the following =20
content :

require 'osx/cocoa'

def NameAndAddress_main_init
   path =3D =
OSX::NSBundle.mainBundle.resourcePath.fileSystemRepresentation
   rbfiles =3D Dir.entries(path).select {|x| /\.rb\z/ =3D~ x}
   rbfiles -=3D [ File.basename(__FILE__) ]
   rbfiles.each do |path|
     require( File.basename(path) )
   end
end

if $0 =3D=3D __FILE__ then
   NameAndAddress_main_init ####### <=3D=3D=3D line 21
   OSX.NSApplicationMain(0, nil)
end

and get the following error :

/Users/yvon/work/CocoaRubyfication/NameAndAddress/build/Default/=20
NameAndAddress.app/Contents/Resources/NameAndAddress_main.rb:21: =20
uninitialized constant NameAndAddress_init (NameError)

then i thought the prob arroses only because i've made use of a upper =20=

case first letter for this file name, then i rearranged all to :

nameAndAddress_main.rb  and everything else accordingly.

and i've discovered, what i've never used before, that a method, =20
within ruby, couldn't start with an upper case letter )))

hopping this could help others,

ok, i see, i've believed it was some idiomatic expression not =20
available to frenchies understanding ;-)

i'd like doing a Rubyfication of my own following the reading of your =20=

pages (which take roughly about one hour including two coffe cups ; =20
it's 9 in the morning here).


but i want to choose a cocoa example wich implement the Apple Event =20
"Get URL", do you know one example implementing that in Obj-C ?

because in one of my apps to responds to typing url in Sfari, as for =20
example, what does "Sogudi" , you type :

man:plutil

in the Safari's Url field and you get the man page on plutil...

in case of success i'd like adding this example to you pages if you =20
permit and correct my poor english.

and also i may have enough time in order to transalte your pages in =20
french, let me know if interested and, in case of yes, what are the =20
requirement, html format and so one to do that translation.

best,

Yvon

yes, you're right about that, too!  Thanks for pointing it out.  In =20
my test program, I set it to 100 but forgot to mention that in the =20

Unfortunately this is an unresolved problem with RubyCocoa.

I'm torn about what to do about this.  I suppose I should include it =20

that we'll fix (or see fixed) soon.

Hi Yvon,

You are right about oc_display -- this issue of name conflicts =20
between Ruby and Objective C is addressed in the next section (3.2).  =20=

I decided to leave the error (along with it's correction) in the =20
article to illustrate the problem.

  I put all my Ruby code in a single file that I named "RTW.rb".  =20
"RTW" came from the initials of "Round Transparent Window"; I'm sorry =20=

for the confusion about that.

very good, i apreciate very much your effort, i'm reading your pages =20

@appleEventManager.setEventHandler_andSelector_forEventClass_andEventID(=20=

self, 'GURL', <?>.kAEInternetSuite, <?>.kAEISGetURL)

[Rubycocoa-talk] translating Apple Cocoa examples to Ruby

[Tim B. <tim...@gm...>]

Lately I've been converting some examples from Apple's Cocoa sample  
code library (http://developer.apple.com/samplecode/Cocoa/index.html)  
to Ruby.  It's given me a few patterns to use for future RubyCocoa  
apps, and it's exposed some of the ways RubyCocoa applications can  
break when the instructions aren't strictly followed.

I wrote up an account of one conversion and put it online here:  
http://www.rubycocoa.com/the-rubification-of-rtw.

I expect to post other conversions as I complete them.  If anyone  
else is willing to share conversions of their own, I'd gladly host  
those online as well.

Ah, ok. If you installed from one of the packages then it'll be using  
the Tiger ruby. If you installed ruby libxml against your own ruby  
in /usr/local/lib then a rubycocoa app will not be able to find the  
libxml ruby libraries. You could try installing ruby libxml using /

not at the time being because i need first to get the right ruby =20

i've not tried out standalinify.rb for that point yet.

i'll investigate first on havibg ruby 1.8.4 within XCode.

if tehir is a bugg within standaloneify i could arrange by myself =20

It ought to include libxml.bundle (assuming that's what the native  
code part of ruby libxml is called), but the libxml.dylib that comes  
from the Mac OS X installation will not be copied.

However, if the native code libxml.bundle is coming from a gem,  
there's a bug in standaloneify that prevents it from working. Is that  
the case?

The ruby that gets used is dependent on which ruby you built  
RubyCocoa against.

[Rubycocoa-talk] question about standaloneify.rb and XCode

[Yvon T. <tho...@fr...>]

Hey all,

a littke question about standaloneify.rb

suppose i put :

require 'xml/libxml'

in my rb_main.rb

does standaloneify.rb include libxslt.framework as RubyCocoa.framework ?

or does i have to include, with all the related, in my bundled app ?

i ask this question because if i use "require 'xml/libxml'" in a  
little trying script it's OK, ruby found "xml/libxm"

however using the latest from a XCode RubyCocoa project i get an error :

/Users/yvon/work/RubyCocoa/BookmarksMerge/build/Development/ 
BookmarksMerge.app/Contents/Resources/rb_main.rb:13:in `require': no  
such file to load -- xml/libxml (LoadError)
	from /Users/yvon/work/RubyCocoa/BookmarksMerge/build/Development/ 
BookmarksMerge.app/Contents/Resources/rb_main.rb:13


may be XCode is using the Apple standard Ruby where i make use of my  
installed ruby in "/usr/local" ?

if this is the case how could i specify, within XCode, the ruby to use ?

best,

Yvon

I don't think Core Image is properly supported yet in RubyCocoa  
(please correct me if I'm wrong). I seem to remember somebody else  
having a go at getting it to work a while back...

I think arbitrary structs are not supported. However, since CGRect is  
structurally the same as an NSRect you can probably get away with

[Rubycocoa-talk] Using structs

[Mario P. \(Sorceforge\) <sou...@er...>]

Good afternoon,

I try to connect Core Image via RubyCocoa to Ruby. To write processed images 
to hard disk, in need an image representation. In one step I have to specify 
a CGRect as the region, which should be taken for further steps. The CGRect 
is a struct defined in CGGeometry (have a look at 
http://developer.apple.com/documentation/GraphicsImaging/Reference/CGGeometry/Reference/reference.html)

In the sources of RubyCocoa I found a way to deal with enums, but not with 
structs. Is this still implemented? And if "yes", how I can make use of it?

I just noticed there are some Objective C examples in

that get installed with Xcode.

Probably worth building them and trying to get things working within  
the Apple-provided examples. Then you might have a better idea of how  
to express it with RubyCocoa.

Right. My original attempt was in squeak with the

problems, so I translated my trials in ruby, but the
results are the same.
