I was using this tutorial: http://flight-manual.atom.io/hacking-atom/sections/package-active-editor-info/
Doesn’t seem to work for me. My code is in the following gist and simplified. https://gist.github.com/mrpotatoes/778fab79921a6d949e8d03d211076032
I don’t get the dock hover on the right side. Help is greatly appreciated so that I can use this in my proper module.
