irb/completion

[Brian McCallister]

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]

you need the realine library installed at configure time and linked against at
compile time.

so either

a) you don't have it. install it and recompile ruby

b) you have it but didn't link against it

0) recompile (once) with LD_RUN_PATH pointing at it
1) run (always) with LD_LIBRARY_PATH pointing at it
2) reconfigure ld to find it for your system

do a man ld.so if this doesn't make sense. bottom line, ruby doesn't have
access to the readline shared library.

cheers.

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_ruby_1.html

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!
