防止在 BufWritePre 期间保存文件 [英] Prevent file saving during BufWritePre

问题描述

我有一个功能可以对当前文件执行有效性检查(以符合我雇主的编码标准).我想在保存之前调用这个函数，即使用 BufWritePre.但是，如果我的检查功能失败，我会阻止保存文件.

I have a function which performs validity checking on the current file (so as to conform to my employer's coding standards). I would like to call this function before saving, i.e. using BufWritePre. However, I would to prevent saving the file if it fails my checking function.

那么，是否有可能突破 BufWritePre 自动命令?

So, is it possible to break out of the BufWritePre autocommand?

我意识到我可以通过重新映射 :write 命令来实现这一点，如图所示 此处，但如果可能的话，我想避免这种情况，因为感觉有点不微妙.

I realise that I could accomplish this by re-mapping the :write command as illustrated here, but I would like to avoid that if at all possible, as it feels somewhat un-subtle.

预先感谢您的建议.

推荐答案

你可以简单地"强制一个错误:

You can 'simply' force an error:

:autocmd BufWritePre *.txt throw "you may not"

如果您想再次保存 .txt 文件

If you wanted to be able to save .txt files again

:autocmd!
:source $MYVIMRC
