"methods" method
57744 [xrfang@ho ma] I tried String.methods-Kernel.methods in irb, found that most methods of

install.rb
57756 [dcarrera@ma ] Could someone tell me how the Ruby 'install.rb' scripts work?
57757 [decoux@mo lo] For an extension
+ 57759 [dcarrera@ma ] Half my frustration comes from the fact that this didn't work.
| 57763 [batsman.geo@] It should work. Perhaps you lack some library required for development,
+ 57760 [dcarrera@ma ] Correction.
| 57792 [lyle@us rs s] There is no "official" procedure for building Ruby packages that include

    57811 [ndrsbngtssn@] How do you then configure Ruby to find the packages there? Could that
    58044 [aamine@lo er] You can use environment variable $RUBYLIB for such purpose.

Matz's slides
57769 [dali@in ul .] I saw the new Matz's slides from Ruby Conference 2002 at www.ruby-lang.org.

Solaris and ruby libraries

Best way to read data?

  + 57954 [tietew-ml-ru] [Re: on error resume next]
  | 57958 [walker@de fc] You are trying to force ruby to become what you know, instead of learning
  | 57959 [gsinclair@so] Couldn't agree more.
  | 57987 [jim@fr ez .o] If I remember from my VB days, the Resume Next resumes at the

Hash 'issues'
