You can configure your IRB sessions to provide tab completion, and other neat things. A page here: http://tinyurl.com/fkuj2 gives details, but the code there can be improved with a few Ruby idioms. Here's what's in mine:
IRB.conf[:AUTO_INDENT] = true
IRB.conf[:USE_READLINE] = true
IRB.conf[:LOAD_MODULES] ||= []
IRB.conf[:LOAD_MODULES] |= ['irb/completion']
Cheers,
Benjohn
If you're in for simplifying you can have it even simpler
IRB.conf[:AUTO_INDENT] = IRB.conf[:USE_READLINE] = true
(IRB.conf[:LOAD_MODULES] ||= ) << ['irb/completion']
Even simpler, on my system (cygwin) it's as simple as writing a single
line into ~/.irbrc:
$ cat .irbrc
require "irb/completion"
:-))
Kind regards

Thanks Robert. Cool that as ".irbrc" is just "required" by IRB at start up, you can do anything you like in it, include requiring other modules, as you do.
As you're being really smart though, I'm going to point out that
(IRB.conf[:LOAD_MODULES] ||= ) << ['irb/completion']
isn't equivalent to
IRB.conf[:LOAD_MODULES] ||=
IRB.conf[:LOAD_MODULES] |= ['irb/completion']
...the latter will ensure only one attempt is made to load the "completion" module, and it'll prevent the array getting cluttered up if you look at it later on... Although it makes absolutely no difference in the end, of course.

My bad. You're right of course, I didn't finish the copy, paste and
mody process properly. That should of course have read
(IRB.conf[:LOAD_MODULES] ||= ) << 'irb/completion'
Still you might get duplicate entries but that doesn't matter that
much here - as you said already.
Thanks for pointing it out!
Kind regards
