Using split panes
The most intuitive way for me to run tests is to use a tmux split pane. I
simply split my screen between my editor and a shell that runs tests (
test in this example). I’ve then set up a vim hotkey (
,r for me) to quickly send “up enter” to the last tmux pane used.
" Repeat last command in the next tmux pane. nnoremap <Leader>r :call <SID>TmuxRepeat()<CR> function! s:TmuxRepeat() silent! exec "!tmux select-pane -l && tmux send up enter && tmux select-pane -l" redraw! endfunction
Even better, I’ve set up
Ctrl-S as a “save-and-repeat” key to make it all happen in one keystroke:
inoremap <C-s> <Esc>:w<CR>:call <SID>TmuxRepeat()<CR>a noremap <C-s> :w<CR>:call <SID>TmuxRepeat()<CR>
Alternatively, you can use vim-dispatch, but it doesn’t support colors and can be disorienting.
