How to fold/unfold HTML tags with Vim
提问by nsbm
Is there some plugin to fold HTML tags in Vim?
Or there is another way to setup a shortcut to fold or unfold html tags?
I would like to fold/unfold html tags just like I do with indentation folding.
是否有一些插件可以在 Vim 中折叠 HTML 标签？
或者还有另一种方法来设置折叠或展开 html 标签的快捷方式？
我想折叠/展开 html 标签，就像我对缩进折叠一样。

I have found zfat(or, equally, zfit) works well for folding with HTML documents. zawill toggle (open or close) an existing fold. zRopens all the folds in the current document, zMeffectively re-enables all existing folds marked in the document.
我发现zfat（或同样地，zfit）适用于折叠 HTML 文档。za将切换（打开或关闭）现有折叠。zR打开当前文档中的所有折叠，zM有效地重新启用文档中标记的所有现有折叠。
If you find yourself using folds extensively, you could make some handy keybindings for yourself in your .vimrc.
如果你发现自己广泛使用折叠，你可以在你的 .vimrc.

If you indent your HTML the following should work:
如果您缩进 HTML，以下内容应该有效：
set foldmethod=indent
The problem with this, I find, is there are too manyfolds. To get around this I use zOand zcto open and close nested folds, respectively.
我发现这个问题是折叠太多了。为了解决这个问题，我分别使用zO和zc来打开和关闭嵌套的折叠。
See help fold-indentfor more information:
有关help fold-indent更多信息，请参见：
The folds are automatically defined by the indent of the lines.
The foldlevel is computed from the indent of the line, divided by the
'shiftwidth' (rounded down). A sequence of lines with the same or higher fold
level form a fold, with the lines with a higher level forming a nested fold.
The nesting of folds is limited with 'foldnestmax'.
Some lines are ignored and get the fold level of the line above or below it,
whichever is lower. These are empty or white lines and lines starting
with a character in 'foldignore'. White space is skipped before checking for
characters in 'foldignore'. For C use "#" to ignore preprocessor lines.
When you want to ignore lines in another way, use the 'expr' method. The
indent() function can be used in 'foldexpr' to get the indent of a line.

Folding html with foldmethod syntax, which is simpler.
用foldmethod语法折叠html，比较简单。
This answer is based on HTML syntax folding in vim. author is @Ingo Karcat.
这个答案基于vim 中的 HTML 语法折叠。作者是@Ingo Karcat。
set your fold method to be syntax with the following:
vim command line
:set foldmethod=syntaxor put the setting in
~/.vim/after/ftplugin/html.vimsetlocal foldmethod=syntaxAlso note so far, the default syntax script only folds a multi-line tag itself, not the text between the opening and closing tag.
So, this gets folded: <div class="foo" id="bar" > And this doesn't <div> <b>text between here</b> </div>To get folded between tags, you need extend the syntax script, via the following, best place into
~/.vim/after/syntax/html.vimThe syntax folding is performed between all but void html elements (those which don't have a closing sibling, like
<br>)syntax region htmlFold start="<\z(\<\(area\|base\|br\|col\|command\|embed\|hr\|img\|input\|keygen\|link\|meta\|para\|source\|track\|wbr\>\)\@![a-z-]\+\>\)\%(\_s*\_[^/]\?>\|\_s\_[^>]*\_[^>/]>\)" end="</\z1\_s*>" fold transparent keepend extend containedin=htmlHead,htmlH\d
使用以下内容将您的 fold 方法设置为语法：
vim 命令行
:set foldmethod=syntax或将设置放入
~/.vim/after/ftplugin/html.vimsetlocal foldmethod=syntax还请注意，默认语法脚本只折叠多行标签本身，而不是开始和结束标签之间的文本。
So, this gets folded: <div class="foo" id="bar" > And this doesn't <div> <b>text between here</b> </div>要在标签之间折叠，您需要扩展语法脚本，通过以下，最好的地方到
~/.vim/after/syntax/html.vim语法折叠在除 void html 元素之外的所有元素之间执行（那些没有关闭的兄弟元素，例如
<br>）syntax region htmlFold start="<\z(\<\(area\|base\|br\|col\|command\|embed\|hr\|img\|input\|keygen\|link\|meta\|para\|source\|track\|wbr\>\)\@![a-z-]\+\>\)\%(\_s*\_[^/]\?>\|\_s\_[^>]*\_[^>/]>\)" end="</\z1\_s*>" fold transparent keepend extend containedin=htmlHead,htmlH\d
