Ace: How do I scroll the editor to a position, not just a line?
I'm using Ace for a collaborative editing experience and I want to be able to scroll to another user's cursor position.
I see that there are editor.scrollToRow(), and editor.scrollToLine() methods, but I can't seem to find any method that works with a cursor object that has position and selectionEnd properties.
What I'd like is to be able to scroll to a position, not just a line. Or if there is a way to convert a position to a line that would be helpful too.
Thanks!

Position is an object like {row, column} so getting a line from it is easy by using position.row.
You can also use
editor.renderer.scrollCursorIntoView({row: 50, column: 1}, 0.5) (0.5 centers the line on screen use 1 for bottom 0 for top)

I guess I'm on an older version where the position is just the character position, but that will be nice when I can upgrade.

Must be something else, that code didn't change much from the very beginning.
If you have chracter index in value string editor.session.doc.indexToPosition(index) can help you to get {row, column} but that is a relatively slow function.

Thanks for the response! You're right about the Ace cursor API. I now think it has to do with my Firepad plugin doing something else weird with it, so there's nothing wrong on the Ace side.
