Could you try to install http://hackage.haskell.org/cgi-bin/hackage-scripts/package/Shellac-0.9.1 and http://hackage.haskell.org/cgi-bin/hackage-scripts/package/Shellac-readline-...

If that works, I'll be content with libedit as well.

They don't work with the patch I sent before, but after adding back a few more functions supported by libedit, I was able to install both packages and successfully run a quick test of shellac-readline in ghci. (Although eventually, someone more familiar with that package may want to run more thorough tests.) I'll work on making a new patch which adds back all of the functionality that libedit supports (including what's needed for shellac-readline). -Judah

Does this work with libedit, too?

Hm... It runs, but doesn't have any effect. It looks like you need to use setBasicWordBreakCharacters instead of setCompleterWordBreakCharacters. (ghci sets both, which is why I didn't notice this before.) Note that with my fix to #998 (sent to cvs-ghc), that hack should no longer be necessary. -Judah

Good point. Fortunately, I'm testing everything on Tiger (10.4.10), so this shouldn't be a problem. -Judah On Jan 9, 2008 2:13 PM, Manuel M T Chakravarty wrote:

Judah,

I completely agree that, at the least on the Mac, using editline is the best solution (as long all necessary functionality is supported).

I am wondering, though, whether you are testing on Tiger or Leopard. When looking at the readline-emulation API of editline after upgrading to Leopard, I had the impression that it included much more functionality than it did on Tiger.
