Hi,
I am using syntax foldling in C files. When all is folded but then a
somewhere in the middle a { is inserted, every fold below in the file
gets unfolded (sometimes it returns to the previous state when the
closing } is inserted, but sometimes not).
I would like to disable this feature if possible, however, keep syntax
based folding. In case it is related to brace matching I do not need
that either.
Is there a way?
I asked the same thing a while back[1]. In the end, Bram explained that
it's slightly complicated to get this right[2]. Personally, I use this
variant of Matt's workaround[3] in my own .vimrc:
" Don't update folds in insert mode
aug NoInsertFolding
au!
au InsertEnter * let b:oldfdm = &l:fdm | setl fdm=manual
au InsertLeave * let &l:fdm = b:oldfdm
aug END
The gist: switch to something other than foldmethod=syntax while in
insert mode, then switch back afterward. It still has the problem that
if you insert a bracket and then insert the closing bracket at two
different times (e.g. to add a level of scope to something), the folds
get messed up. But, it's better than the complete craziness of updating
the folds as you're entering them in the first place.
