I'm trying to create a very simple shortcut that saves the buffer and cleans the writing message after a second.

nmap <silent> <leader>w :w<CR>:sleep 1<CR>:echo ""<CR>

This works fine but I would like to make the message cleaning asynchronous (so I don't get stuck for 1 second). Looking into asynchronous solutions, it is not clear if the way to achieve that would be via timer_start, defer_fn, or something else.

  • Welcome to Vi and Vim! FWIW, I don't often feel a need to clear the message :) besides, any time I use :, /, or ? it goes away. Also :redraw works.

One way to do it is with :h timer_start(). Create a function which will write the buffer, create a function which clears the message and create a timer to call this function. Then map <leader>w to call this function:

nnoremap <silent> <leader>w :call SaveAndClear()<CR>

function! SaveAndClear()
    function! ClearMessage(timer)
        echo ""
    call timer_start(1000, 'ClearMessage')

The syntax could be simplified with a lambda (I copied the syntax of an example in :h closure):

nnoremap <silent> <leader>w :w<CR>:call timer_start(1000, {-> execute("echo ''", "")})<CR>

Also, always create non-recursive mappings nnoremap unless you know what you are doing.

  • Why echoing something at all, when a redraw just does it? Also I usually just hit Ctrl-L to get rid of that write status message, no need to do it automatically and then possibly just miss it, because you are distracted for that 1 second :/ May 19, 2021 at 7:40
  • I do agree that I don't see the point of deleting the status automatically I would never use that on my own config but if OP think they need it... ¯\_(ツ)_/¯ And yes there are better ways of suppressing the message but I think what's important here is the call of a timer from a mapping, once they know how to do it OP can change the actual action for whatever they want.
