Thread: [Rubycocoa-talk] Enabling Tk bindings on Snow Leopard

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I guess Tk bindings for Ruby and Python were removed in Snow Leopard,
even though Tk is still included. Is there a way to enable/install the
bindings for Ruby without recompiling Ruby?

Hi Eric,

OK, the first thing to know is that you don't need to recompile ruby  
to add in bindings.  Bindings are added by using Ruby extensions.   
Basically, at start up, the Ruby interpreter looks in a well-known  
location in your file system, and runs any native extensions that it  
finds there.  I don't know if you've already worked with Ruby  
extensions, but if not, this is pretty much the canonical reference  
for them:
http://ruby-doc.org/docs/ProgrammingRuby/html/ext_ruby.html

Out of curiousity, what makes you think that Tk bindings have been  
removed in Snow Leopard (I'm still on Leopard, so I can't test it)?

Personal experience --

>> require 'tk'
LoadError: no such file to load -- tk
	from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in
`gem_original_require'
	from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in
`require'

Also, I read it on the Web. I don't remember the exact page now, but I
did just find this one:
<http://groups.google.com/group/comp.lang.ruby/browse_thread/thread/22e0e72994155258>

Sure enough, there is no tk.rb under /System/Library/Frameworks/Ruby.framework.

When I have time I will try recompiling it.

Now that I think about it, I downloaded and installed RubyCocoa, so
that should have overwritten the RubyCocoa that came with the OS,
right? Or would that just replace the Cocoa-specific parts, and leave
the core Ruby stuff in place? (If I compile my own Ruby, I don't want
to lose the Cocoa-specific parts.)
