自动完成时不区分大小写

Question

我在互联网和Vim的帮助下搜索了很多，所以我希望这不是一个重复的问题......无论如何：

有没有办法在Vim的自动完成功能中打开不区分大小写？我显然不打算使用它进行编码，但是我在Vim中写了很多文本，我想念复杂和/或长词。

例如，假设我写了：

  

火山肺矽病   是一种疾病...

现在我要写：

  

肺炎患者

然后<C-n>和bang :-P

Answer 1

根据文档，您似乎可以使用以下两个选项：ignorecase和infercase

  'infercase' 'inf'     boolean (default off)
            local to buffer
            {not in Vi}
When doing keyword completion in insert mode |ins-completion|, and
'ignorecase' is also on, the case of the match is adjusted depending
on the typed text.  If the typed text contains a lowercase letter
where the match has an upper case letter, the completed part is made
lowercase.  If the typed text has no lowercase letters and the match
has a lowercase letter where the typed text has an uppercase letter,
and there is a letter before it, the completed part is made uppercase.
With 'noinfercase' the match is used as-is.

根据文档，它适用于ins-completion，即在插入模式下自动完成。

您应该在.vimrc中添加以下选项：
set ignorecase
set infercase

对于问题中描述的用例没有用，但可能还是有趣的：

:set wildignorecase  " Ignore case when completing file names and directories.
                     " Has no effect when 'fileignorecase' is set, which is the case (no pun intended)
                     " by default for systems where case in file names is normally ignored,
                     " notably Windows.

在SO：D上找到它 这是一个非常新颖的功能，只有7.3.072可用。

我不知道wildignorecase，但是

:set ignorecase

为我做了伎俩（使用vim 7.2）。
