The other big one is 'FXRuby' (http://fxruby.sourceforge.net/)
My personal favourite is gtk2.

#include<std_disclaimer.h>
#include<opinions.h>
#define  FLAMES   0

I would say that the following 3 are the main choices.  This is how I view 
them:

Tk
===
  Pro:	Easiest to use and learn.  Multi-platform.
  Con:	Somewhat ugly and not terribly powerful.

Gtk2
====
  Pro:	Modern, powerful and looks great.  Semi-multiplatform.
	Not hard to use, but there is more to learn than with Tk.
  Con:	The Windows port is a bit behind I think.

Fox
===
  Pro:	Modern, powerful and multi-platrofm.

You should not miss 
 - Fox (FXRuby) 
 - fltk  (ruby-fltk)

But you can get useful info right from here:

Seems to! I looked at the Fox page, though, and it doesn't list Mac OS X 
as a platform it supports ... yet FreeRIDE has a screenshot running on 
OS X. How did they do that? Did they run it under X11 on the Mac?  I was 
actually hoping for something that could run on Aqua as well as Win32 
and X11.

Thanks!

I don't think that exists yet.  There is a project to port Gtk1 to Aqua.  
It's fairly close, but won't be done for a few months I think (and it's 
gtk1, not 2).

If you are going for something that looks native:

Ruby-GNOME2 looks native under Linux.
Ruby-Cocoa  looks native under 0S X
FXRuby looks sort of native under Windows (I think it looks fine).

ASN.1 basic/distinguished encoding rules for Ruby?

Has anyone built a library for ASN.1's BER or DER for Ruby?
I can't find "ASN" in the RAA...

RubyCocoa and addresses of pointers

Some methods in Objective-C require the address of a pointer, so the method
can fill in the value of the pointer. How do I do this in RubyCocoa?

As an example, here's some Objective-C code

    // fpDate is an IB outlet
    NSDateFormatter *dateFormatter = [fpDate formatter];
    NSCalendarDate *templateDate;
    BOOL conversionResult;
    NSString *error;
    BOOL conversionResult;

    conversionResult = [dateFormatter getObjectValue:&templateDate
					   forString:[fpDate stringValue]
				    errorDescription:&error];

getObjectValue:forString:errorDescription: takes two arguments that are
addresses of pointers. The method returns objects in those parameters.

Is there a way to do this in RubyCocoa?

Re: Change to /.../.match("foo") behaviour in 1.6.8?

Hi,

In message "Change to /.../.match("foo") behaviour in 1.6.8?"

Put "*" before the expression, e.g.
