Hi,

It’s very exciting to see that the Ruby community is quite active. Thanks
for the help. BTW, is there a KB style archive of previous discussion so
that we can search for help before asking here?

Thanks!
Shannon

I don’t know what ‘in’ is used for, but another way to do this might
be
if [array_of_strings].index(myString) then…

Or:

array_of_strings.include?(myString)

I’ve often thought that Array#=== should do the same thing as
Array#include?
It seems wasted to be the same as ==.

Maybe it’s just me.

Check out the FAQ (http://www.rubygarden.org/iowa/faqtotum) as well. Also see
the newcomers’ list (recently posted) for some other resources.

Cheers,

Actually, the list / newsgroup is mirrored on the web, so Google tracks
everything.
Therefore this list is effectively a KB by itself, it even has KB numbers as
message id’s.

For example, try Google “threading problem Ruby”

The first hit yields KB article number 18699:

http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/18699

Of course, you could also search in Google groups directly under
comp.lang.ruby, but then you don’t get the article id.

I should add that the more official link to an article, once the id is know
is:

http://www.ruby-talk.org/18699

some write
[ruby-talk:18699]
but this can’t clicked directly in mail and news editors.
