强制 vim 覆盖外部更改 [英] force vim to overwrite external changes

问题描述

我使用 Vim 7.4 (Mac OS) 来编辑和运行 Lua 脚本.我已经在我的 .vimrc 中映射了一个键来保存当前缓冲区并运行一个外部脚本.

I use Vim 7.4 (Mac OS) to edit and run Lua scripts. I've mapped a key in my .vimrc to save the current buffer and run an external script.

.vimrc 中的按键映射:

The key map in .vimrc:

map V :w!<CR> :!python "$HOME/tools/client/concli.py" --lua %<CR>

它工作正常，但每隔一段时间，Xcode(触摸外壳命令)就会触摸"文件.然后当我点击映射键时，vim 警告我文件已在外部更改，我必须确认写入.

It works fine but every once in a while the files are 'touched' by Xcode (touch shell command). Then when I hit the mapped key vim warns me that the file has been changed externally and I have to confirm to write to it.

这很烦人，因为文件经常被触及.如何强制 vim 在没有提示的情况下覆盖外部更改?我试过'w！'没有成功.

This is quite annoying since the files are often touched. How could I force vim to overwrite external changes without prompting? I tried 'w!' without success.

谢谢你，劳伦特

推荐答案

确实，:w! 无法关闭覆盖确认，而 :set autoread 不会在这种情况下也无济于事.有效的是指示 Vim 在写入之前显式检查更改:

Indeed, the overwrite confirmation cannot be turned off with :w!, and :set autoread doesn't help in this case, neither. What does work is instructing Vim to explicitly check for changes before the write:

:checktime | w
