Use Emacs master branch with native compilation flag enabled.
I tried Pgtk branch, but it is not always kept up to date with master (currently
3+ months behind) and could have some issues that aren't always tested. It does
mean Wayland integration is imperfect, but right now it is good enough (with few
minor annoyances).
Emacs + Gcc (native-comp)
native-comp is currently in upcoming release branch (28.0.50), while pgtk branch
is yet to be merged. Using both above features is easily available with
emacs-overlay provided by nix-community.
I still haven't been able to get cachix build cache to work, so currrently this
config builds full Emacs on machine. This extends system rebuild by 30+ minutes
and reduces system useability for the same duration.
Updating system frequently is not currently on my radar anyway, and I can
probably stomach keeping the machine humming for 60+ minutes of system
rebuild (compiling Emacs itself takes 25-30 min),
as long as I do it less than once per week. Will see how it goes.
PipeWire is new Linux audio and video streams.
Previously I used PulseAudio, and while it worked, it was less than
perfect. Pulse used bit much processing, and in general had few bugs.
Pipewire is supposed to be lighter, more stable, and it can use high
quality codec for bluetooth.
I took this opportunity to move sound-related config to its separate
module (sound.nix). This is a beginning to nicely move inpendent config
sections to their own modules. Sound config has pretty much zero
relations with rest of the config, so it made sense to move it in
separate file. Perhaps I can do the same with other stuff, maybe some services.
Initial setup to email from within emacs.
That required setting up above stuff, detailed below:
mbsync : sync maildir with email host/provider (gmail)
mu : index and search maildir
msmtp : send mail
All of the above have good module under home-manager, making it *relatively*
straightforward to set the whole thing up.
