The GNU Emacs Architecture: Unlocking the Core [pdf]

It looks great. I have not read it to completion just yet, but merely scrolling through the document leaves me with a feeling that the author got tired and decided "this is a good stopping point."

To be fair, writing a book about Emacs is a Sisyphean effort by definition - this sea is a bottomless abyss of hackery abundance, and any meaningful effort to explain it is worth a celebration.

This is a bachelor's thesis from University of Uppsala submitted in March 2026.

I was having trouble accessing the Digitala Vetenskapliga Arkivet site (linked in headline) directly, so uploaded it here (link expires in 3 days):

This is great! You should make a web version or add it to the wiki.

I started the Hacker's guide on the emacs wiki many years back. I think this doc was much needed.

Love to see that Emacs can still capture the atention of new CS students.
