Is it possible to get range of lines currently visible in the browser?
After some research I merely found method
getViewport(), which returns, as I understand, the line range which are currently rendered in the DOM, but since CM generally renders several (default 10, configurable) lines before/after current visible lines, it’s not what I am trying to find.
I would like to find lines, which are visible to the user (I don’t care what is in DOM, I care about the lines that are visible with respect to current scroll).
I could implement the feature myself, if elements with class
CodeMirror-line bore the information of the line number (I want the solution independent on line number gutters). If CM does not provide API for the visible lines, can I modify line rendering via a plugin to include that information?
