Another indispensable item in a programmer’s toolbox is a hard wrapping editor plugin. I’m using hard-wrap for Atom. The problem it solves is reformatting a set of lines to not go beyond a wrap guide. Mine wrap guide is set to 80 characters, and it was always painful to readjust the comments and docstrings for them not to go beyond this guide. With this plugin it’s just a stroke of a hotkey.
