Vim 折叠以 { 结尾的每一行，但不折叠类 [英] Vim folding every line ending in { but not classes

问题描述

我打算折叠所有以 { 结尾的行，但不折叠类.到目前为止，我想出了这个命令:

I intend to fold all the lines ending in { but not classes. So far I have came up with this command :

:%g/.\{-}\(class\)\@!.*{$/normal! zf%

但这也会匹配包含 class 的行.

But this would match also the lines containing class.

推荐答案

有几个问题:

1. 来自:help/\@!:您不能使用\@!"在匹配位置之前查找不匹配的位置".使用 \@<!，在其中包含可能的字符，并删除无用的(因为它没有锚定)非贪婪的第一个匹配.
2. :global 命令将光标置于匹配行的第一列，因此添加一个 $ 使 % 一直工作.
3. 后续的内折必须在外折打开的情况下定义:zv.

1. From :help /\@!: "You can't use "\@!" to look for a non-match before the matching position". Use \@<!, include the possible characters in between in there, and drop the useless (because it's not anchored) non-greedy first match.
2. The :global command places the cursor on the first column of matching lines, so add a $ to make the % work all the time.
3. Subsequent inner folds must be defined with the outer fold open: zv.

因此:

:%g/\%(class.*\)\@<!{$/normal! $zvzf%
