Disabling horizontal split in Ace Editor

Question

I am using Ace Editor. As is shown in the page that I linked, the editor appears with an empty portion on the right side (which I believe is the split view) with a vertical line between it and the (main) editing space. How can I turn this off?

Answer 1

It is not a split view but a print margin - simple line at the specified column, to help seeing when lines become too long.

To disable it use

editor.setOption("showPrintMargin", false)

Answer 2

This worked for me. Add the following piece of code and the line just vanishes off.

editor.setShowPrintMargin(false);
