vim - Clear search highlight on autocmd BufWrite -

-

i tried of suggestions in 3 questions:

get rid of vim's highlight after searching text
how rid of search highlight in vim
vim clear last search highlighting

it's :noh, , works when type manually. want happen on bufwrite, tried multiple ways, none of worked:

function! removehighlight()     :noh endfunction  autocmd bufwrite * :call removehighlight() autocmd bufwrite * :noh autocmd bufwrite * :execute "normal! :noh\<cr>"

debuging echoms , adebug\<esc> in function , in third autocmd show execute successfully, :noh has no effect.

(also tried :let @/ = "" worked clears search pattern, not i'm looking for. want rid of highlight til pressing n or similar)

using bufwritepost doesn't have effect, either.

it workaround can set nohlsearch autocmd. can add mapping set n , n.

au bufwrite * set nohlsearch nnoremap <silent> n n:set hlsearch<cr> nnoremap <silent> n n:set hlsearch<cr>

or maybe better, check if set

au bufwrite * set nohlsearch  nnoremap <silent> n n:call togglehlback()<cr> nnoremap <silent> n n:call togglehlback()<cr>  function! togglehlback()   if &hlsearch == 'nohlsearch'     set hlsearch   endif endfunction
