文件保存期间语法高亮随机消失 [英] Syntax highlighting randomly disappears during file saving

问题描述

我正在使用 vim 编辑一些 python 文件，最近偶尔会发生在我将缓冲区保存在 vim 中后语法突出显示消失的情况.我尝试重置 syntax on 和 set filetype=python 但无济于事.我根本不知道是什么导致了这个问题，所以现在我只有最少的诊断信息.但是之前有没有人遇到过这种情况，或者事情会在哪里崩溃?

I'm using vim to edit some python files and recently it occurs sporadically that the syntax highlighting disappears after I save the buffer inside vim. I tried to reset syntax on and set filetype=python but to no avail. I have no clue of what causes this problem at all, so right now I have minimal diagnostic info. But has anyone encountered this before, or where could things break down?

推荐答案

这不是解决方案，但在评论中很难写/读.

This is not a solution, but it's hard to write/read in the comments.

我的意思是当我开始修复我自己的 .vimrc 时，我在搞乱语法/突出显示，这就是我注意到它的原因.syntax on/syntax enable 只是为文件加载做准备(在 BufNewFile/BufRead 中添加了很多 au).因此，如果某些插件在编写文件时弄乱了语法/高亮设置，则必须再次加载该文件才能使所有魔法"发生，仅设置 filetype 是不够的.执行 :au BufRead ，您将看到启动语法时添加的所有自动命令.但是必须加载该文件才能获取所有设置.

I meant that I was messing around with syntax/highlighting when I start to fix my own .vimrc, thats why I noticed it.
syntax on / syntax enable is only preparing for file load stuff (adding a lot of au to BufNewFile / BufRead). So if some plugin is messing with syntax/highlight settings when writing the file, the file must be loaded again for all "magic" to happen, it's not enough with setting filetype. Do :au BufRead and you will see all autocommands added when starting syntax. But the file must be loaded then to get all settigs.
See this:> syntax-loading

如果你不想重新加载文件，试试syntax enable，我认为这与syntax on不同.
或者也尝试做 :doautocmd filetypedetect BufRead %，参见 > autocmd-execute

If you don't want to reload the file, try syntax enable, I think that is different to syntax on.
Or try also doing :doautocmd filetypedetect BufRead %, see > autocmd-execute

我不知道是什么导致了问题，是你吗?如果您添加了一些自动命令，或者使用自己的颜色/语法?
否则，在得到解决方案之前，您或许可以尝试在 .vimrc 的末尾添加 autocmd BufWritePost * <使用上述有效的命令>，使用 <代码>augroup 在这种情况下.

I don't know what is causing the problem, can it be you? If you added some autocommands, or doing own colors/syntax?
Otherwise, until you get a solution, you can perhaps try to add autocmd BufWritePost * <with the commands above that works> at the end of your .vimrc, use augroup in that case.

这是一个例子:

augroup myResetSyntax
  au!
  autocmd BufWritePost * syntax enable | doautocmd filetypedetect BufRead "%"
augroup END
