183605 [rcs bgoark.n] I have tested two implementations of wxRuby/wxPython applications (stock

183623 [svolkov comc] Could you please explain me why String instance methods return subclass,
183746 [g_ogata optu] String (and Array) methods that return new strings (arrays) tend to

^ named method arguments with defaults
183629 [eliben gmail] What is the current idiomatic approach to pass named arguments to a
183634 [devlists-rub] def a_method(*options)
183637 [eliben gmail] This works when I remove the asterisk from the (*options).
183642 [devlists-rub] Language support for named arguments will be in Ruby 2.0 (hopefully :P)
183659 [gene.tani gm] There's a discussion of how to simulate keyword args in the draft Ruby

^ ruby -w and '(...) interpreted as grouped expression'

183631 [matz ruby-la] It's caused by a space before argument parenthesis.  I just removed it

183646 [minkoo.seo g] a = Matrix[(0..3).map { Array.new(5) }]

183718 [noone nowher] Have you tried running it with 'ruby -rprofile'?

^ [RCR] abstract method in Ruby
183647 [kwa kuwata-l] To define abstract method in Ruby, I use NotImplementedError like the
+ 183656 [halostatue g] In the last four years of using Ruby, I thought I needed abstractmethods in the first few months. Then I learned what value Modules asmixins gave me.
| 183704 [kwa kuwata-l] Thanks Austin,
| 183709 [logancapaldo] I think you're over engineering. Let's consider the Enumerable module
| + 183711 [benjohn fysh] supposed to implement something. You could point that out with a
| + 183749 [kwa kuwata-l] Logan,
|   + 183751 [meinrad.rech] if you want serious discussion then it would be great if you were able to
|   + 183784 [logancapaldo] charset=US-ASCII;
|   | 183837 [kwa kuwata-l] I have no intention to argue about dynamic vs. static.
|   | + 183839 [ara.t.howard] careful - ruby is strongly typed.  what it is not is statically typed.
|   | + 183844 [logancapaldo] charset=US-ASCII;
|   + 183804 [halostatue g] Actually, the method #each is not abstract in Enumerable. It's aprerequisite. There's a difference. In the C++ and Java world, it's*necessary* to define a prerequisite method as an abstract method,because without a method definition, the compiler goes stupid and can'tfind anything and won't then compile your code at all. Ruby sees thecall to #each with a block and says "okay, I'll trust that you'vesatisified this until I hit it at run time."
|   | 183814 [benjohn fysh] *snip*
|   + 183815 [matz ruby-la] class Base
|     183823 [ara.t.howard] how about something very simple?  i use this in my own code
|     183824 [ mfp acm.org] It fails in the very way matz indicated.
|     + 183827 [ara.t.howard] class Module
|     + 183838 [kwa kuwata-l] I don't want the just same as Java's abstract method.
|       + 183841 [ara.t.howard] class Module
|       | + 183870 [nobu ruby-la] This hides NoMethodError within the super method too.
|       | | 183918 [ara.t.howard] class Module
|       | | + 183973 [pit capitain] All those implementations which actually create dummy methods prohibit
|       | | + 184022 [nobu ruby-la] Simply separate Module#abstract_method and Class#abstract_method.
|       | |   184060 [xmlarchitect] Hmm, just some thoughts.
|       | |   184061 [xmlarchitect] Oops, my apologies, forgot an end in example.
|       | |   184066 [dblack wobbl] I fear that  "duck-typing prototype" is a contradiction in terms.
|       | |   184071 [xmlarchitect] Good points both, thanks.
|       | |   + 184072 [xmlarchitect] My apologies for double posting, I must have confused  Gmail somehow.
|       | |   + 184073 [avdi.grimm g] The point of duck typing is that your code automatically ensures it,
|       | |     184076 [xmlarchitect] Ok, I think I see what you mean. I didn't have the right understanding of
|       | |     184094 [Stephen.L.Mo] Unit tests?
|       | + 183987 [mental rydia] Hmm, what about cases where the super exists, but calls something
|       + 183843 [matz ruby-la] It's caused by mix-in, a kind of multiple inheritance.  The above is

183654 [mutoh highwa] Ruby-GetText-Package-1.3.0 is now available.

^ Threads and Deadlocks
183655 [riko despamm] It seems that the standard ruby interpreter is able to detect deadlocks
+ 183664 [drbrain segm] There's nowhere to throw an exception to, all threads are blocked
| 183666 [riko despamm] What happens then? Is there any documentation about this (I'd rather not
| + 183686 [bob.news gmx] format=flowed;
| | 183829 [riko despamm] Thank you very much.
| + 184336 [headius head] JRuby currently uses Java threads to implement Ruby threads, and therefore
+ 183894 [nobu ruby-la] ThreadError will be raised in the main thread.
  183928 [bob.news gmx] Hm, but why then isn't it caught by a clause "rescue Exception => e"?
