Save and run at the same time in Vim

Question

I do a lot of Python quick simulation stuff and I\'m constantly saving (:w) and then running (:!!). Is there a way to combine these actions?

Maybe a "save and run&qu

Answer 1

I got the following from the Vim tips wiki:

command! -complete=file -nargs=+ shell call s:runshellcommand()
function! s:runshellcommand(cmdline)
  botright vnew
  setlocal buftype=nofile bufhidden=wipe nobuflisted noswapfile nowrap
  call setline(1,a:cmdline)
  call setline(2,substitute(a:cmdline,'.','=','g'))
  execute 'silent $read !'.escape(a:cmdline,'%#')
  setlocal nomodifiable
  1
endfunction

But I changed new to vnew on the third line, and then for Python I have the following:

map  :w:Shell python %

Hitting F9 saves, runs, and dumps the output into a new vertically split scratch buffer, for easy yanking, saving, etc. It also hits c-w so I only have to press h/c to close it and move back to my code.
