FWIW, I've been following this thread because I empathize with Dan in
this report: depending on the system I use, emacs -Q gets me either
Ubuntu Mono (GNOME/Ubuntu 22.04), Noto Sans Mono (Plasma/Debian 12) or
Source Code Pro (Plasma/openSUSE Tumbleweed).
In practice I customize Emacs to pick DejaVu Sans Mono in every setup,
but that's a decision I take for incidental reasons (character coverage,
bold/italic variants); so indeed I happen to
> just specify the same font
but I can imagine wanting to keep the system's default _family_, yet
have a consistent font _size_ across all my setups, in which case having
to spell out the font in my dotfiles is a bother.
(Granted, the X resource solution cited above might work? Would it work
--with-pgtk on Wayland?)
(Granted², as soon as each "setup" differs in screen size, resolution,
or density, "a consistent font _size_ across all my setups" probably
requires bespoke face heights for each setup; still, that does not mean
I'd want to mess with the _family_)
FWIW², if I were to attempt to "just set the size, ignoring the font" in
my dotfiles, I'd probably go with either
;; (1)
(set-face-attribute 'default nil :height my/height)
or
;; (2)
(let* ((family (face-attribute 'default :family))
(font-desc (format "%s-%s" family my/size)))
(add-to-list 'default-frame-alist
(cons 'font font-desc)))
? Not saying that's worth documenting, just hoping that'll help Dan
sort out his config.
