Description Sebastian Zartner

Build ID: M20080911-1700

For text editors there's an option for specifying the "Displayed tab width". This option is currently missing for the compare editor.
Therefore a text field in the preferences under General->Compare/Patch would be the best way to control this.

This is especially important when you are using formatter options with a different tab width.

I mean, right now I'm using Java built-in conventions for the formatter and this is using a tab width of 8.
When comparing files with the compare editor, I see it using a display tab width of just 2: the result is wrongly indented code shown in the compare editor.

I tried to change the displayed tab width in Window | Preferences | General | Editors | Text Editors, but it seems like it doesn't have effect on the compare editor.

Is there a workaround for this?

The general text editor pref works for compare editors too. However to see the change in the compare editor you need to reopen it. I think you can consider it as a workaround.

I'm on one of 4.3 IBuilds.

I did close and reopen the compare editor and also restarted Eclipse, but it had no effect. We have been forced to change our formatter policy to "spaces only" because of this problem :-(

Please note I was using Eclipse 4.2.1, I don't know if something has changed in 4.3.
