Daniel Mai has a nice video on how he uses Org mode to organize his Emacs init file. I’ve written about this before but some of you may prefer, or at least enjoy, watching a video on the subject.
This appears to be the first of several videos on the subject so Mai restricts himself to showing how he organizes the Org file and how he uses the use-package package to install and configure his packages. He promises to go into some of the details in future videos.
If you’ve reached the point where you’re thinking, “I really should refactor my init file” you should consider organizing it as an Org file. Doing that makes it easy to add commentary on why your doing things a particular way or what a custom function is for. One of the big benefits, I think, is that Org mode’s outline paradigm makes it natural to organize your init file in a reasonable way. That, in turn, makes it easy to find things either by just looking at the headings or using one of the excellent Org mode search functions.
In any event, the video is enjoyable and only 12 minutes long so it should be easy to fit it into your schedule.
