Aptana 3 - How remove trailing whitespaces on save

I'm trying Aptana3 but I don't find an essential feature :

Remove trailing whitespaces开发者_运维问答/empty lines on save.

This is now possible.

Preferences -> Aptana Studio -> Editors

Check "Remove trailing whitespace characters"

Not possible with Aptana 3.1. See

• http://jira.appcelerator.org/browse/APSTUD-814

But since Aptana is (was?) based on Eclipse, you can also try

• How to auto-remove trailing whitespace in Eclipse?

Works fine with this Eclipse plugin http://andrei.gmxhome.de/anyedit/ Tested with Aptana 3.0.7
