如何强制 vim 拼写检查器忽略 lowercase/uppercase 错误

Question

我发现 here and here 如何强制 Vim 拼写检查器忽略大写字母的单词，使其不被检查。但我的情况恰恰相反。我想忽略以更正形式包含大写字母的单词。

所以在句子中：

欧洲最佳

只有单词 chozen 是错误的。

如何实现？

感谢任何提示。

I don't think that Vim has a setting for this. One workaround is to create a new spellfile that contains everything in your current spell file(s) but with lowercase letters only:

1. Create a new buffer containing everything from the spell file(s) currently in use:

   :spelldump
   

2. Delete lines that don't contain any upper-case characters. This isn't strictly necessary, but there's no point keeping duplicate entries for lower-case words:

   :v/\u/d
   

3. Convert the entire file to lower-case, ignoring lines that contain the locations of the spell files:

   :v/^#/norm gu$
   

4. Save the file:

   :w ~/.vim/spell/lowercase.utf-8.add
   

5. Start using this file in addition to the standard files in Vim's $VIMRUNTIME directory. Note that Vim uses a default 'spellfile' value internally if the setting is empty, so if you already have any existing spell files, you will need to ensure that they are included in this setting (which accepts a comma-delimited list):

   :set spellfile=~/.vim/spell/lowercase.utf-8.add
   

   Note that if you set this option in a running instance of Vim, it doesn't seem to take effect for spell-checking until you interact with it (by, e.g. using the zg command.)

The above doesn't affect the way that Vim detects lower-case words at the start of a sentence as spelled incorrectly. You can disable this with the 'spellcapcheck' option:

:set spellcapcheck=
