Is there a way to hide the vertical ruler in Ace?

By vertical ruler I mean the vertical line in the editor at 80 chars which helps to keep lines under a certain length.

I'd like to give my users the options to enable/disable it If possible

Found it, you need to use this:

editor.setShowPrintMargin(false);
