Line numbers

[brendand]

Is there a function to display line numbers along the left side of the view? The syntax highlighting is great. Just needs line numbers.

This is not supported yet, and to be honest I don't currently have the time to implement it, but feel free to send a PR if you do so.

Highlightr just does the coloring using the highlightrjs library - it's an NSTextStorage, but the actual rendering is still done by Cocoa's NSLayoutManager and NSTextContainer.

I'm going to give this a shot using a vertical NSRuler, based on the information in the following links:

If you've achieved this already, please stop me and help a guy out ;)

Edit: Added another link.
