这样的事情会工作。只要创建的文件类型自动命令的地图＆LT; F4＆GT; 或任何你想保存并编译和运行程序。它使用exec来构建该字符串，并使用shellescape逃脱的文件名。

Something like this would work. Just create filetype autocmd that map <F4> or whatever you want to save and compile and run the program. It uses exec to build the string and uses shellescape to escape the file name.

autocmd filetype python nnoremap <F4> :w <bar> exec '!python '.shellescape('%')<CR>
autocmd filetype c nnoremap <F4> :w <bar> exec '!gcc '.shellescape('%').' -o '.shellescape('%:r').' && ./'.shellescape('%:r')<CR>
autocmd filetype cpp nnoremap <F4> :w <bar> exec '!g++ '.shellescape('%').' -o '.shellescape('%:r').' && ./'.shellescape('%:r')<CR>

％是当前缓冲区的文件名。 ％，R 是缓冲文件名不带扩展

% is the current buffer filename. %:r is the buffer filename without extension
