VIM [编译]运行​​快捷方式 [英] Vim [compile and] run shortcut

问题描述

基本上我想要的是在vim键盘快捷键，让我[编译]运行​​当前正在编辑C，C ++或Python程序。在伪code：

Basically what I want is a keyboard shortcut in vim that lets me [compile and] run the currently being edited C, C++ or Python program. In psuedocode:

when a shortcut key is pressed:
    if current_extension == 'c' then
        shell: gcc this_filename.c -o this_filename_without_extension
        if retcode == 0 then shell: ./this_filename_without_extension
    else if current_extension == 'cpp' then
        shell: g++ this_filename.cpp -o this_filename_without_extension
    if retcode == 0 then shell: ./this_filename_without_extension
    else if current_extension == 'py' then
        shell: python this_filename.py
    end if
end key

我知道我可能会问一个有点多，但会喜欢它，如果这是可能的！

I realise I might be asking a bit much but would love it if this was possible!

推荐答案

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
