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

Question

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

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.

Answer 1

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

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

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

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

To open all blocks, is Ctrl + 0

Answer 2

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.

Answer 3

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

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

Answer 4

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.

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.

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 .

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

Answer 5

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

Answer 6

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".

Answer 7

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

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

Answer 8

Just to sum up:

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

Answer 9

If you are using PyDev in Eclipse, its Ctrl0 and Ctrl9 for collapse all and uncollapse all respectively. Ctrl- and Ctrl= to collapse individual methods when your cursor is on the line of the method declaration.

Answer 10

Right click on the circles +/- sign and under Foldings select Collapse All

Answer 11

I had the same problem and found out Folding can be enabled or disabled, and in my case got disabled somehow.

To solve it, simply right click on the line numbers/breakpoint section (vertical bar in the left of the editor), then under the 'Folding' section chose 'Enable folding'.

ctrlshift/ should be working fine after.

Answer 12

Shortcuts that worked for me in Versions Oxygen.2 Release (PHP/WINDOWS 7) were

1. Collapse all code blocks: CTRL + SHIFT + NUMPAD_DIVIDE
2. Expand all code blocks : CTRL + NUMPAD_MULTIPLY

Answer 13

In case you don't have a separate numpad, you can activate the overlapping numpad using the number lock- this varies with the type of keypad-> fn + numlk for hp

then try ctrl + shift + numpad_Divide

should work fine

Answer 14

Collapse all : CTRL + SHIFT + /

Expand all code blocks : CTRL + *

Answer 15

I noticed few things:

Ctrl+/ toggles Folding-enabled or -disabled.

It is Ctrl+* that expands. Ctrl+Shift+* collapses just like Ctrl+Shift+/
