Re: [Haskell-cafe] OK, so this VIM thing -- how do I make it actually work?

Hi Michael, I can also confirm this occurs on my Vim 7.0 (I'm also running Edgy Eft). Notably it (the red highlight on _ and loss of syntax highlighting) only seems to occur when there is a \section (or sub) command within the .lhs (I am also using lhs2tex). Hadn't noticed this before as I tend not to place sectioning commands in the .lhs and use a main .tex containing sequences like: \subsection{Module foo} \include{foo} Not sure if this is present in the Feisty Fawn binaries, I guess someone should file a bug report? :) Dave, On 05/06/07, Michael T.

I've given up on getting a decent text editor for editing Haskell (specifically literate Haskell -- plain Haskell works fine in GEDIT). Instead I fire up VIM and get ... a total mess. At first 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? For good measure, here's the beginning of the lhaskell.vim file that comes with my vim distribution ( 7.0 in the Ubuntu archives). If it's desired I can attach the whole file. (It isn't actually all that large.)
