Subject: Re: Ruby readline - completion based on already-entered commands


hi,

i'm new to ruby, and having the problem Bill Atkins was having with
the readline library.  i searched the archives and found this thread.
unfortunately no great solution.  there was the partial solution from
Dave Baldwin that involved changing the word split character.  as he
pointed out the real problem is that ruby readline doesn't provide the
whole line buffer so one cannot do context line completion.

i'm wondering on the follow up process.  there is a patch to fix this
at:

   http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/54796

it was posted back in nov 2002.  but hasn't made it in so far (checked
1.8.3), but has been a problem for 3 or 4 years.  was the patch no
good?

thanks for any insight

matt
