[LAUGH] Proposal For New Ruby Mailing List Subjects

Ruby Syntax: 'initialize' versus 'init'
178307 [checketts@gm] ...
+ 178311 [james_b@ne r] I suspect people call to_* more often than they call initialize.
+ 178318 [gmurray@cl u] There is a difference in wrapping to interface to C
+ 178321 [matz@ru y- a] It can be very critical when the name of initializing method conflicts

Debian, gem(?) , and libraries
178319 [furufuru@cc ] I'm using Ruby on Debian GNU/Linux.  Ruby itself

+ 178337 [stefan@ma li] I'm using gems on Ubuntu (and were using it on debian as well).
+ 178367 [ruby@an hr p] } Hello all,
  178498 [furufuru@cc ] Thank you all who responded.
  + 178524 [jim@we ri hh] RubyGems only works for software explicitly packaged as gems.  Although

I Broke Ruby (i.e. Missing the Brutally Obvious)
178324 [mjudge@su ve] It's been yet another late Friday.  It's practically a lifestyle by this
178329 [g_ogata@op u] Because it hasn't been defined when "class B < A" is evaluated.
178558 [mjudge@su ve] Thanks for your help, George.  That's really interesting how the ruby

Fixnum#to_a
178326 [levin@gr nd ] 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. ;-)

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

  178488 [wybo@se va y] Thanks all for the very valuable explanations and suggestions.
  178571 [mark@mw ld n] 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@gm ] 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) }
| 178379 [bauer.mail@g] Duh... yea, should have read the previously posted link,

  | + 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@we ri hh] 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@ro co ] Careful with that, I think hash order is undefined?

How to use Ruby interpreter as Windows DLL library?

178356 [dblack@wo bl] Whoops.  Let me check.  (I'm in London but at least intermittently
178357 [dblack@wo bl] 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@ru y- a] 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

Quiz #65, Principle of Great Surprise, and Array.delete sledgehammer
