In my vimrc I have a key mapping for switching buffers that also automatically resizes the splits by calling a function:

nnoremap <silent> <M-h> <c-w>h:call Splitresize()<CR>

I also would like to automatically switch to insert mode when entering a terminal buffer, so I wrote:

autocmd BufEnter term:* startinsert

The problem is that when use <M-h> to change to a terminal buffer, the autocmd is executed before the function call, so that :call Splitresize() is printed in my terminal.

Is there a way to ensure that the function is called before the autocmd is executed?

Use <cmd> pseudo key to call a function without involving command-line mode (:h <cmd>)

For example:

func! Splitresize()
        echom "Resize!!!"
endfunc

nnoremap <silent> <C-h> <c-w>h<cmd>call Splitresize()<CR>
nnoremap <silent> <C-l> <c-w>l<cmd>call Splitresize()<CR>

augroup test | au!
        autocmd! BufEnter term://* startinsert
augroup END

    Is that two opportunities in one day you've had to use <cmd> in an answer? Pretty good for a command I don't recall seeing mentioned before. :)

    @BLayer, indeed :) Recent vim also has it.

  • Oh, awesome! I was just going to comment that I hope they port it there. Looks super handy.
