有没有办法折叠 Eclipse 中的所有代码块？

Is there a way to collapse all code blocks in Eclipse?

提问by ambertch

Eclipse has that "+/-" on the left to expand and collapse blocks of code.

Eclipse 左侧的“+/-”用于展开和折叠代码块。

I've got tens of thousands of lines to go through and would really like to just collapse everything, and selectively expand blocks to look at them.

我有数以万计的行要经过，并且真的很想折叠所有内容，并有选择地展开块来查看它们。

There is a hotkey, mapped by default to Ctrl+Shift+NUM_KEYPAD_DIVIDE.

有一个热键，默认映射为Ctrl+ Shift+ NUM_KEYPAD_DIVIDE。

You can change it to something else via Window -> Preferences, search for "Keys", then for "Collapse All".

您可以通过 Window -> Preferences 将其更改为其他内容，搜索“Keys”，然后搜索“Collapse All”。

To open all code blocks the shortcut is Ctrl+Shift+NUM_KEYPAD_MULTIPLY.

要打开所有代码块，快捷方式是Ctrl+ Shift+ NUM_KEYPAD_MULTIPLY。

In the Eclipse extension PyDev, close all code blocks is Ctrl+ 9

在 Eclipse 扩展PyDev 中，关闭所有代码块是 Ctrl+9

To open all blocks, is Ctrl+ 0

要打开所有块，是Ctrl+0

In addition to the hotkey, if you right click in the gutter where you see the +/-, there is a context menu item 'Folding.' Opening the submenu associated with this, you can see a 'Collapse All' item. this will also do what you wish.

除了热键之外，如果您在看到 +/- 的装订线中右键单击，则会出现一个上下文菜单项“折叠”。打开与此相关的子菜单，您可以看到“全部折叠”项目。这也会做你想做的。

A "Collapse All" command exists in recent builds (e.g. 3.2 M6) and is bound to Ctrl+Shift+NUM_KEYPAD_DIVIDEby default.

A“全部折叠”命令存在于最近构建（例如3.2 M6），并绑定到Ctrl+ Shift+NUM_KEYPAD_DIVIDE默认情况下。

You can also configure it in Preferences->Editor->Keys.

您也可以在 Preferences->Editor->Keys 中进行配置。

The question is a bit old, but let me add a different approach. In addition to the above hot-key approaches, there are default preference settings that can be toggled.

这个问题有点老了，但让我添加一个不同的方法。除了上述热键方法之外，还有可以切换的默认首选项设置。

As of Eclipse Galileo (and definitely in my Eclipse Version: Indigo Service Release 2 Build id: 20120216-1857) language specific preferences can open up new files to edit which are already collapsed or expanded.

从 Eclipse Galileo 开始（当然在我的 Eclipse 版本中：Indigo Service Release 2 Build id：20120216-1857）语言特定的首选项可以打开新文件进行编辑，这些文件已经折叠或展开。

Here is a link to Eclipse Galileo online docs showing the feature for C/C++: http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse.cdt.doc.user/reference/cdt_u_c_editor_folding.htm.

以下是显示 C/C++ 功能的 Eclipse Galileo 在线文档的链接：http: //help.eclipse.org/galileo/index.jsp?topic=/ org.eclipse.cdt.doc.user/ reference/ cdt_u_c_editor_folding。嗯。

In my Eclipse Indigo I can open the Folding Preferences window via : menu/ Window/ Preferences/ Java/ Editor/ Foldingand set all options on so I can open files by default that are completely collapsed.

在我的 Eclipse Indigo 中，我可以通过 : 打开折叠首选项窗口menu/ Window/ Preferences/ Java/ Editor/ Folding并设置所有选项，这样我就可以在默认情况下打开完全折叠的文件。

Ctrl+Shift+/and Ctrl+Shift+*works great for Aptana Studio 3.

Ctrl+ Shift+/和Ctrl+ Shift+*非常适合 Aptana Studio 3。

Apart from that you can always use Window > Preferences > Editors > Foldings to enable it

除此之外，您始终可以使用 Window > Preferences > Editors > Foldings 来启用它

回答by wisbucky

If you always want the code collapsed by default, go to Windows > Preferences. Search for "folding". Then check all the items under "Initially fold these elements".

如果您始终希望代码默认折叠，请转到 Windows > 首选项。搜索“折叠”。然后检查“初始折叠这些元素”下的所有项目。

Right click on the +/- sign and click collapse all or expand all.

右键单击 +/- 符号，然后单击全部折叠或全部展开。

If you are using PyDev in Eclipse, its Ctrl0and Ctrl9for collapse all and uncollapse all respectively. Ctrl-and Ctrl=to collapse individual methods when your cursor is on the line of the method declaration.

如果您在 Eclipse 中使用 PyDev，则其Ctrl0和 分别Ctrl9用于折叠所有和取消折叠所有。Ctrl-并Ctrl=在光标位于方法声明的行上时折叠单个方法。

Just to sum up:

简单总结一下：

1. anycode:
   • ctrl + shift + NUMPAD_divide = collapse all
   • NUMPAD_multiply = exand all
2. pydev:
   
   • -ctrl + 0 = collapse all
   • -ctrl + 9 = exand all

1. 任何代码：
   • ctrl + shift + NUMPAD_divide = 全部折叠
   • NUMPAD_multiply = 展开所有
2. pydev：
   
   • -ctrl + 0 = 全部折叠
   • -ctrl + 9 = 全部展开
