[Patch] Readline command completion for everything

[gsauthof]

Hi,

I wrote a patch that improves the readline command completion feature of hugs. I.e: - added completion of function names and constructors - added completion of command names (:<cmd>) - added completion of module names (e.g. after :browse , etc.) - only do filename completion where it makes sense (e.g. after :load , etc.) - expand use of tilde (~) in filenames (previously it was completed but not recognized by hugs) - read and write the history from/to ~/.hugs_history - make hugs recognize :help

Patch is attached.

Best regards Georg Sauthoff

Hm, trac eats my newlines? The WikiFormatting link ( http://hackage.haskell.org/trac/hugs/wiki/WikiFormatting) contains spam and the suggested formatting does not work in the Comment Preview (e.g. '* ')... Strange.

Thanks. I've committed it to our shiny new darcs repository, though it does have some limitations:

• the names include things that aren't in scope (:names has the same problem)
• the names don't include qualified names
• the words completed are space-delimited, rather than being Haskell ids
• completion for :load works for filenames only, not modules

Still, it's a start, and better than nothing.
