irb/completion

Hmm, any reason I'd be unable to use 'irb/completion' out of the box in
1.8.2-preview2 ?

It likewise ignores the request to use it in my .irbrc

[mccallister@kite ~/src/eva]$ /usr/local/ruby-1.8.2-preview2/bin/irb
irb(main):001:0> require 'irb/completion'
=> false

[mccallister@kite ~/src/eva]$ ruby -v
ruby 1.8.2 (2004-07-29) [powerpc-darwin7.5.0]

[mccallister@kite ~/src/eva]$ uname -a
Darwin kite.forthill.int 7.5.0 Darwin Kernel Version 7.5.0: Thu Aug 5
19:26:16 PDT 2004; root:xnu/xnu-517.7.21.obj~3/RELEASE_PPC Power

Yes, this was just covered here recently. Short story:

1. irb/completion requires GNU's readline lib.

2. Mac OS X does ship with the lib, but not the header files for Ruby
to find in it's build process.

3. So, you either need to bring readline support to your Ruby install,
described here:

http://richkilmer.blogs.com/ether/2003/10/building_r...

Or, build and install GNU readline and then Rebuild your Ruby install
so it will notice it.

I used the latter and it worked like a charm.

Good luck.

Much appreciated! Was getting fooled on readline as I had earlier set
up an alias to run irb in rlwrap. Doh!
