What is it?

It is my fork of Emacs, if you will.

This is Emacs' master branch, with stuff added (and some stuff removed, which I was too lazy to support).

I am using this on a daily basis on macOS with an init file that I can also use with an unchanged master. I make no efforts to find or fix bugs in stuff that I don't use personally.

My init file uses use-package and straight, and I am using packages like vertico, consult, corfu, magit, org, gnus etc., so I'd say it's pretty backwards compatible.

Who's that?

C-h i d m emacs RET s gerd RET

What's not there/not supported

• Documentation
• Tests
• Support for purespace

Common Lisp packages

What's there

You can use packages much like in Common Lisp. For details, read lisp/emacs-lisp/pkg.el and src/pkg.c, and maybe admin/cl-packages.org, although I haven't kept that up-to-date for some time, I guess.

What's the plan?

None. I don't think CL packages will land in Emacs in my lifetime. The resistance against this, or anything CL for that matter, is simply too high among current Emacs maintainers.

So, why do this? Because I can. Some people like to tinker with their init files, others go a step further :-).

New GC

This is an incremental and generational GC that is based on Ravenbrook MPS.

I ported this to the mainline GNU/Emacs (branch scratch/igc on savannah) and it wsa developed further there and here. Pip Cet has taken over further development at some point because I don't want to maintain this (or anything else) in mainline Emacs.

Works well for me on macOS. I'm using this daily.

Child frames on ttys

This has meanwhle landed in master on savannah.

DTrace support

My Emacs is now beginning to be a DTrace USDT provider. Configure --with-dtrace=no to disable it. This is only tested on macOS. Development is ongoing.
