I found the following code on a stackexchange post:
http://tex.stackexchange.com/questions/1548/intelligent-paragraph-reflowing-in-vim
The code is for environment-aware formatting in LaTeX.
It's not longer working quite the way I want it---I think it is interacting
with one of my other plugins that has been updated---so I'd like to try to
modify it. However I don't have a great knowledge of the Vim scripting
language, so I don't really understand what's going on in the code. Could
someone explain it to me?
Alternatively/additionally, if you have a good solution for formatting in
LaTeX, please share!
Here's the code. It's also on the Stackexchange post in case the formatting
gets messed up:
" Reformat lines (getting the spacing correct) {{{
fun! TeX_fmt()
if (getline(".") != "")
let save_cursor = getpos(".")
let op_wrapscan = &wrapscan
set nowrapscan
let par_begin =
'^\(%D\)\=\s*\($\|\\start\|\\stop\|\\Start\|\\Stop\|\\\(sub\)*section\>\|\\item\>\|\\NC\>\|\\blank\>\|\\noindent\>\)'
let par_end =
'^\(%D\)\=\s*\($\|\\start\|\\stop\|\\Start\|\\Stop\|\\place\|\\\(sub\)*section\>\|\\item\>\|\\NC\>\|\\blank\>\)'
try
exe '?'.par_begin.'?+'
catch /E384/
1
endtry
norm V
try
exe '/'.par_end.'/-'
catch /E385/
$
endtry
norm gq
let &wrapscan = op_wrapscan
call setpos('.', save_cursor)
endif
endfun
nmap Q :call TeX_fmt()<CR>
