VIM autocmd to compile and run single source file.

vimrc.vim

if has("autocmd")
  augroup vimrcCompileMap
    " Remove ALL autocommands for the current group. This prevents having the
    " autocommands defined twice (e.g., after sourcing the .vimrc file again).
    autocmd!

    " Map <F5> to save, compile and run single source file.
    if has("win32")
      autocmd FileType cpp nnoremap <buffer> <F5> :w<CR>:!cls && cl /EHsc % && %< <CR>
      autocmd FileType python nnoremap <buffer> <F5> :w<CR>:!py % <CR>
    else
      autocmd FileType c nnoremap <buffer> <F5> :w<CR>:!gcc -o %< % && ./%< <CR>
      autocmd FileType cpp nnoremap <buffer> <F5> :w<CR>:!g++ -o %< % && ./%< <CR>
