I've given up on getting a decent text editor for editing Haskell

I think maybe I've screwed up a whole bunch of settings or
something, so I nuke everything in my home directory that begins
with .vim and then, for added measure, head over to /usr/share and
nuke the entire ./vim directory tree. I then reinstall vim (from
the Ubuntu Edgy archives) to get a brand new set of config files
unsullied by my hands.
I still get a dog's breakfast.
A screen shot of what I'm seeing with a representative example of
a .lhs file to show what I mean can be found at http://
img357.imageshack.us/img357/5798/gvimexamplezv4.png. (I've pared
it down to the minimum I could find that shows the behaviour
clearly.) The problems I'm seeing are the ugly white-on-red for
underlines, the lack of any kind of differentiation for keywords/
operators/etc. vs. identifiers (although some punctuation is
recognized, specifically curly braces), comments not being noted,
etc. Basically it looks like the Haskell is simply not being
recognized at all (and, if the @saBinds@ thing is what I think it
is, it looks like some latex isn't being recognized fully either).
Can anybody vim-centric please take a look at this and give me a
few educated guesses as to what is happening here?
Yes, I can. What you see happening is that the syntax highlighter
doesn't get
completely switched from TeX mode to Haskell mode on the change marked
by \begin{code} (and back again on \end{code}). Therefore, lone
underscores
(which are usually in error in TeX outside of mathematics) are marked
as errors.
This should be fixed. I'll look into it. The reason I've never run
into it is simple:
I tend not to use underscores in my Haskell code. :)
With regards, Arthur van Leeuwen.
