^ [LAUGH] Proposal For New Ruby Mailing List Subjects
178305 [zedshaw zeds] Hey,

^ Ruby Syntax: 'initialize' versus 'init'
178307 [checketts gm] While programming with Ruby, I've grown to love just how clear and concise
+ 178311 [james_b neur] I suspect people call to_* more often than they call initialize.
+ 178318 [gmurray clou] There is a difference in wrapping to interface to C
+ 178321 [matz ruby-la] It can be very critical when the name of initializing method conflicts

+ 178367 [ruby anthrop] } Hello all,
  178498 [furufuru ccs] Thank you all who responded.
  + 178524 [jim weirichh] RubyGems only works for software explicitly packaged as gems.  Although

^ I Broke Ruby (i.e. Missing the Brutally Obvious)
178324 [mjudge surve] It's been yet another late Friday.  It's practically a lifestyle by this

178326 [levin grunde] class Fixnum    def to_a(base=10,min_length=0)      self.to_s(base).rjust(min_length).split(//).map { |c| c.to_i(base) }    end  end
178352 [chneukirchen] It should be twos-complement for negative numbers, of course. ;-)
+ 178354 [levin grunde] 12345.encode(10) #=> [5,4,3,2,1]
+ 178358 [chneukirchen] For fun, an implementation of encode/decode.

^ how to vary sort's block?
178331 [wybo servaly] When I have an array of objects (Thing's, say) with two properties (say
+ 178347 [bob.news gmx] The easiest is probably to use sort_by.
| 178355 [wybo servaly] this does not allow for more complex sorts, like on name *and* amount,

  178488 [wybo servaly] Thanks all for the very valuable explanations and suggestions.
  178571 [mark mwilden] Agreed. C# is the same.

^ Extract hash into local variables?
178332 [cool_screen_] Is there a Ruby function similar to PHP's extract/list? What I'd like to
+ 178340 [bruno.celest] Maybe args.inspect
+ 178345 [bob.news gmx] You cannot do that as local variables have to be declared in the code.
| 178353 [gene.tani gm] Robert's correct in the general case, but you can read a hash and have
+ 178377 [bauer.mail g] args.each_pair { |k, v| instance_variable_set("@#{k}", v) }

  | + 178433 [gene.tani gm] I think on this specific point you're wrong about python.  Writing to
  | | 178438 [gene.tani gm] it's here too
  | + 178472 [chneukirchen] If that's true, consider it a good reason *not to*. ;-)
  | + 178483 [jim weirichh] It may be common in Perl, but it is just as misguided there as well.
  + 178384 [cool_screen_] def extract(hash)
    178388 [cool_screen_] def foo(args = {'a'=>1, 'b'=>2, 'c'=>3})
    178402 [rosco roscop] Careful with that, I think hash order is undefined?

^ How to use Ruby interpreter as Windows DLL library?
178341 [sunexdev mai] I have an idea (program, that uses Ruby interpreter). And I dont know

  178391 [sunexdev mai] Thanks a lot for your way!!! Thanks!  Thanks!  Thanks! =)

^ rcrarchive broken?
178346 [bob.news gmx] Application error (Rails)
178356 [dblack wobbl] Whoops.  Let me check.  (I'm in London but at least intermittently
178357 [dblack wobbl] OK, the MySQL daemon had died for some reason.  It should be OK now.

^ [OT] Re: Ruby Syntax: 'initialize' versus 'init'
178349 [chneukirchen] Did the T object system influence the design of the Ruby object system?
178365 [matz ruby-la] No.  I've heard it was pretty interesting but I didn't have any chance
178471 [chneukirchen] It's very lightweight and almost trivial.  In fact, I once ported it

+ 178373 [bob.news gmx] I'm a bit confused: where are the WeakReferences your subject mentions?
| 178387 [vikkous gmai] The call to __id__ creates the weak reference. Anyway, I consider it a
