Hi, Ivan!

Unfortunately, I cannot reproduce your problem. With my Vim configuration, I get this: https://ibb.co/e6RLKc. Interestingly, the syntax hightlighting I get generally looks quite different from the one you get.

I don’t know how to get a change into Vim’s default syntax/lhaskell.vim. Also, my patch might not be optimal (it almost duplicates some code).

All the best,
Wolfgang

Hi Wolfgang,

Thanks.

That change does help, but it still gets confused.

Could that change be made permanent though? Could it be added to vim's default lhaskell.vim?

Cheers

Ivan

Hi, Ivan!

Does this problem occur with code environments or only with spec environments? At least Vim 7.4 does not mention spec in syntax/lhaskell.vim. I have patched this file such that it does all the things with spec that it does with code, and it works just fine. The patch is as follows:

78c78
<     if search('\\documentclass\|\\begin{\(code}\)\@!\|\\\(sub\)*section\|\\chapter|\\part','W') != 0
---
>     if search('\\documentclass\|\\begin{\(code}\)\@!\|\\begin{\(spec}\)\@!\|\\\(sub\)*section\|\\chapter|\\part','W') != 0

All the best,

Hi cafe,

The lhaskell edit mode for lhs2tex documents in vim gets confused when a dollar is used in code.

This also makes the spellchecker ignore text paragraphs (until a matching $ is found).

Where should this be reported?

This list is named as maintainer in the Ubuntu package vim-runtime's lhaskell.vim syntax file:

" Maintainer:           Haskell Cafe mailinglist <haskell-cafe@haskell.org>
