Eclipse Luna how to enable code completion?

Question

Eclipse

Switched from Aptana to Eclipse Luna.
I was unpleasantly surprised, automatic completions work only in the html editor. In css and js only through ctrl+space. Terribly inconvenient out of habit.
In the js editor, it is possible to enable auto-completion, and then only after pressing the trigger "."
Are there any solutions or plugins? Maybe I'm doing something wrong

Answer 1

Found a solution.
In the file workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.wst.jsdt.ui.prefs
change the line
content_assist_autoactivation_triggers_java=.
on
content_assist_autoactivation_triggers_java=._abcdefghijklmnopqrstuvwxyzABCDEFGH‌

Answer 2

I don’t know what settings exactly in Luna, but in the standard one, pick here:
Windows menu -> Preferences -> Java -> Editor -> Content assist
