有没有办法像“if”语句一样折叠 eclipse 子块？

Is there a way to fold eclipse sub-blocks like an "if" statement?

提问by Shawn

Currently Eclipse only fold the java doc and at function level, but when reading long methods, there could be quite a lot of if/else etc, is there a way to fold them?

目前Eclipse只折叠java文档和函数级别，但是在阅读长方法时，可能会有很多if/else等，有没有办法折叠它们？

It appears Eclipse does not have built-in support for folding if/else statements but allows folding for other more complex cases like Anonymous inner classes. Try looking for plugins like this one(last modified 2007, try it if it supports your Eclipse version).

Eclipse 似乎没有内置支持折叠 if/else 语句，但允许折叠其他更复杂的情况，如匿名内部类。尝试寻找像插件这一个（最后修订2007年，尝试它，如果它支持Eclipse版本）。

in updated versions of Eclipse

在 Eclipse 的更新版本中

Change folding preferences at:

在以下位置更改折叠首选项：

Window -> Preferences -> C/C++ -> Editor -> Folding -> Enable folding of preprocessor branches (#if/#else)

Enable folding using ctrl + shift + /

启用折叠使用 ctrl + shift + /

回答by stacker

No, in the Preferences Dialog (Menu Window/Prefernces): Java/Editor/Folding you may choose,

不，在首选项对话框（菜单窗口/首选项）中：Java/Editor/Folding 您可以选择，

• Comments
• Head Comments
• Inner Types
• Members and Imports

• 注释
• 头条评论
• 内部类型
• 成员和进口

if Enable Folding is checked.

如果启用折叠被选中。

If you wan't to do this because the blocks are so long that can't reconize the structure you should consider to split if/else blocks into methods using Alt-Shift-M (Extract Method)

如果您不想这样做，因为块太长而无法重新调整结构，您应该考虑使用 Alt-Shift-M（提取方法）将 if/else 块拆分为方法

Ok, this is a little bit older, but maybe someone could find this useful: In most cases you can surround the piece of code by an additional pair of scope brackets, and to remember what you folded you can add a line comment.

好吧，这有点旧，但也许有人会发现这很有用：在大多数情况下，您可以用一对额外的范围括号将代码段括起来，并且为了记住折叠的内容，您可以添加行注释。

For example, if you want to collapse the following:

例如，如果要折叠以下内容：

int SectionA_var1;
int SectionA_var2;
int SectionA_var3;
int SectionA_var4;
int SectionA_var5;
int SectionB_var1;

just add the brackets an the comment:

只需添加括号和评论：

{ // SectionA
    int SectionA_var1;
    int SectionA_var2;
    int SectionA_var3;
    int SectionA_var4;
    int SectionA_var5;
}
int SectionB_var1;

Then you get the (-) sign and you can collapse the whole section to this:

然后你会得到 (-) 符号，你可以将整个部分折叠成这样：

{ // SectionA[...]
int SectionB_var1;

No plugin necessary, and until now I had no situation where this gave me any downsides, except that you cannot use it on a top level declaration to collapse methods.

不需要插件，直到现在我还没有遇到这给我带来任何缺点的情况，除了您不能在顶级声明中使用它来折叠方法。

For now, there is built-in function.
Click "Window->Preferences->C/C++->Editor->Folding" and then enable appropriate option you want.
Apply, close and either refresh project or reopen eclipse.

目前，有内置功能。
Click "Window->Preferences->C/C++->Editor->Folding" and then enable appropriate option you want.
应用、关闭并刷新项目或重新打开 eclipse。

For Python, i.e. Eclipse/PyDev, go to Windows > Preferences > PyDev > Editor > Code Foldingand check all the boxes.

对于 Python，即 Eclipse/PyDev，请转到Windows > Preferences > PyDev > Editor > Code Folding并选中所有复选框。

As weird as it looks like, sounds like developers never thought about that. if you have a big if statement or any switch/loop ... just use notepad++ to be able to fold/unfold

尽管看起来很奇怪，但听起来开发人员从未想过这一点。如果你有一个很大的 if 语句或任何开关/循环......只需使用记事本++就可以折叠/展开

3. "Start Identifier" = { ; End Identifier = }
4. click "Apply and Close"
5. Reopen java source editor you will see "if" or "for" block is collapsable
