There's <a href="http://www.emacswiki.org/emacs/FoldingMode" rel="nofollow noreferrer">folding mode</a>, a minor mode. Unfortunately it's intrusive: you have to manually annotate the folds with specialized comments, which clutter the code when you aren't using the mode (or when sharing code with others who don't use it). A better mode would not change your code to work.

Let me add: there's a duplicate of this that's worth a look: <a href="https://stackoverflow.com/questions/1085170/how-to-achieve-code-folding-effects-in-emacs">How to achieve code folding effects in Emacs</a>.

hide-show (<code>hs-minor-mode</code>) is a minor mode that will do something like this...

The default key-binding to trigger the folding is <code>C-c @ C-c</code> which I find pretty cumbersome. But then I don't use it much, either.

blocks|key|979323|text|您可能需要查找函数set-selective-display和变量selective-display。不完全是您想要的，但是它允许您根据缩进级别隐藏行。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|979324|entityMap^0|9|L|X|H|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

You might want to look up the function <code>set-selective-display</code> and the variable <code>selective-display</code>. Not exactly what you want but it lets you hide lines based on indentation level.

blocks|key|979326|text|我用的是折叠。来自emacs+wiki：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|979327|折叠-dwim.el是Emacs折叠/大纲模式的统一用户界面。它支持folding.el、hideshow.el、outline.el、TeX-fold.el和nxml-outin.el。|979328|你可以在这里找到它：|979329|http://www.emacswiki.org/emacs/FoldDwim|offset|length|979330|我在我的.emacs里有这个：|979331|(require+'fold-dwim)

I use fold-dwim.el. From the emacs wiki:

fold-dwim.el is a unified user interface for Emacs folding/outlining modes. It supports folding.el, hideshow.el, outline.el, TeX-fold.el, and nxml-outln.el

You can get it here:

<a href="http://www.emacswiki.org/emacs/FoldDwim" rel="nofollow noreferrer">http://www.emacswiki.org/emacs/FoldDwim</a>

I have this in my .emacs:

<pre><code>(require 'fold-dwim)
(global-set-key [(C kp-4)] 'fold-dwim-hide-all)
(global-set-key [(C kp-5)] 'fold-dwim-toggle)
(global-set-key [(C kp-6)] 'fold-dwim-show-all)
</code></pre>

Keep in mind that you still need to activate hs-minor-mode, folding-mode, etc. but I find it easier to use them this way.

blocks|key|895231|text|您可能会看到的其他内容是nxhtml-模式；它不折叠代码，但根据其类型，它确实会以不同的方式突出显示混合代码(即HTML和PHP)。这使你在可理解性方面获得了类似的好处，而不像折叠模式那样笨拙。我认为这种方法更适合Emacs，首先因为代码折叠似乎是一种面向鼠标的想法，并不能很好地适应基本上以键盘为中心的Emacs接口，第二，因为Emacs可以轻松地导航一个大文件，使代码可以在不妨碍您的情况下保持可见。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|895232|entityMap|0|LINK|mutability|MUTABLE|url|http://ourcomments.org/Emacs/nXhtml/doc/nxhtml.html^0|C|9|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Something else you might look into is <a href="http://ourcomments.org/Emacs/nXhtml/doc/nxhtml.html" rel="nofollow noreferrer">nxhtml-mode</a>; it doesn't fold code, but it does highlight mixed code (i.e. HTML and PHP) differently depending on its type. That gives you a similar gain in comprehensibility without the awkwardness of folding-mode. I think that approach is more suited to Emacs anyway, first because code-folding seems like a mouse-oriented idea that doesn't adapt well to the basically keyboard-centric Emacs interface, and second because Emacs eases navigating a large file to an extent that code can stay visible without getting in your way.

blocks|key|895270|text|如果您实际上需要“隐藏特定区域而不是试图理解语法”(与隐藏和其他基于解析的解决方案不同)，并且“不需要编辑代码”(与折叠不同)，那么，我想，您的意思是不希望区域在不同的编辑会话之间持久。然后你可以使用http://www.emacswiki.org/emacs/HideRegion隐藏用户选择的区域.|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|895271|(但这很奇怪。带有持久标记的折叠小模式似乎是一个更方便的解决方案。)|895272|entityMap|0|LINK|mutability|MUTABLE|url|http://www.emacswiki.org/emacs/HideRegion^0|2S|15|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

If you actually need "something to hide a given region rather than it trying to understand the syntax" (unlike hideshow and other solutions based on parsing) and you "don't want to have to edit [your] code" (unlike folding), then, I assume, you mean you don't want the regions to be persistent between different editing sessions. Then you might use <a href="http://www.emacswiki.org/emacs/HideRegion" rel="nofollow noreferrer">http://www.emacswiki.org/emacs/HideRegion</a> to hide user-selected regions...

(But that's strange. The folding minor mode with persistent marks seems to be a far more convenient solution.)

An excellent feature of Dreamweaver is <a href="http://andrewcerniglia.com/blogImages/77437/Dreamweaver_codeFolding.jpg" rel="nofollow noreferrer">code folding of any lines of text</a> -- recursively!

It's fantastic, I can fold any text or code, regardless of language. I work with existing systems; I don't edit well-written code or code in one language etc. mostly HTML mixed with god-knows-what. Folding lines makes understanding a lot easier and quicker. Sadly, this is the only feature I like in Dreamweaver.

Is there any code folding for Emacs in a similar aim?

可能重复：Dreamweaver的一个优秀特性是 --递归！太棒了，我可以折叠任何文本或代码，不管语言如何。我使用现有的系统；我不会用一种语言编辑写得很好的代码或代码等等，主要是HTML与天晓得的混合。折叠行使理解变得更容易和更快。可悲的是，这是我唯一喜欢的在梦中的功能。Emacs有类似目标的代码折叠吗？
