Eclipse Indigo: shift+tab outdent (indentation) does not work anymore

Asked 27/6, 2011 at 11:27 Answered 18/3, 2017 at 23:8

After installing the new Eclipse Indigo, the outdent does not work anymore when I press shift+tab on a line. Is there any setting which activates this again?

Maybe this is related to the PHPeclipse plugin... – Hydrodynamic 27/6, 2011 at 11:32

Same problem here (eclipse indigo with PHPEclipse), have you resolve this error? – Ectoenzyme 8/7, 2011 at 9:59

same problem here, eclipse juno... did you solve it in the last year and half? :P – Fragile 22/1, 2013 at 13:14

@Fragile there is a new nightly build for PHPEclipse and it seems to work with Eclipse Juno :-) – Hydrodynamic 22/2, 2013 at 15:48

Problem still actual for Eclipse Kepler

in Main Menu -> Window -> Preferences -> PHP -> Formatter -> {your formatter profile} -> Edit -> Identation -> General Settings:

change tab policy to Spaces and indentation size to 4 (or any desired amount).

if default formatter profile is set then ... -> Formatter -> {your formatter profile} -> SHOW -> .. – Roundlet 3/6, 2015 at 11:45

After applying google for-matter my Shift + tab wasn't working, but this solved me. Thanks – Piranha 25/10, 2018 at 9:6

Okay, so I am currently using Eclipse Luna Service Release 1a (4.4.1) and I was experiencing this problem too after switching from whitespace tabbing (4 spaces) instead of standard tab spacing.

The problem for me was that the area I was trying to de-tab/outdent/shift-tab (or whatever you want to call it) had a mix of 4xspaces and actual tabs in it.

Check if this is the case for you. If it is, you should do the conversion from one to the other. To do this, highlight everything in the effected area, then CTRL+F and replace all instances of however many spaces you are using, with "\t".

Make sure that the "Regular expressions" flag is checked.

SHIFT+TAB only seems to work correctly if only tabs or only spaces are used for indentation and won't do anything at all if there is a mix.

Also, naturally, ensure that the correct settings are applied for your tab policy in Main Menu -> Window -> Preferences -> PHP -> Formatter -> {your formatter profile} -> Edit -> Identation -> General Settings.

The functionality works fine and as intended for me since I did this. Make sure to restart the IDE as I have observed that it will subtly tend to stick to old tabbing habits in strange ways if you do not.

Seems like a pretty glaring bug, someone in the Eclipse open source community could fix? – Chloroform 14/4, 2016 at 7:59

It may have something to do with the formatter settings (preferences->java->code style->formatter). I've experienced today the same problem on Eclipse Juno and managed to solve it by setting the indentation size to 4 and the tab size to 4 in the indentation tab. It might be worth to give it a go and play with these settings.

For those who none of the other answers worked, just try to install PDT (Php Development Tools). It has the right hot keys for performing this action. I solved this way.
