Strange line-spacing in headers?

Strange line-spacing in headers?

Hello gentlepeople!

I get my Emacsen from emacsformacosx.com and just upgraded from
Emacs-28.2 to Emacs-29.2 on macOS Ventura.

I immediately realized that someone had been playing havoc with fonts.
It took me a bit of research to find

(custom-set-faces
 '(gnus-header ((t (:inherit fixed-pitch)))))

That "kind of works". I do get the fixed-width font I want ( = my
default font), but the line-spacning in the displayed headers
(To/From/Subject) is different than the line-spacing in the message
body. In the header, the lines are further apart.

I wonder if that's inherited from the GNUS default font, rather than
from the font I've configured? I cannot find where it's adjusted. Does
anyone of you happen to know?

... or should I approach this in some totally different way?

I append a screenshot for illustration.

				Best regards,
				  /Liman

Interesting!

Maybe that depends on the theme loaded?

I'm using the Tao theme, still running Emacs27, screenshot attached.

That could be, but *I* didn't change anything between Emacs28 and
Emacs29, so if it's a new theme, it came with Emacs29. And I still
wonder where that knob sits that I need to tweak.

... and I believe it pertains to font properties and "font-lock" stuff
(for want of a more precise term), as the line-height differs within the
same buffer/window.

The search goes on ... 😉

Thanks. You are on some Linux distro, right? (Just curious if it
my problem pertains only to macOS.)

I wonder what would happen if you were to try that with Emacs29?

The snapshot was from my main notebook still running Debian11, that's
the only reason to still be on Emacs27 there.

A snapshot from a fresh (old `~/.emacs*` removed) Emacs29 on XFCE in
Voidlinux:

Ack.

Thanks! That looks OK.

The easy way to find out is to move point to one of the header lines and
then "C-u C-x =" (what-cursor-position but with C-u to ask for all the
details)!  One of the things this will tell you is the face(s)
associated with where point is.

For the record, I don't see extra spacing in my gnus article view.

AHH!! I've been looking for something along those lines! Will
investigate!

Many warm thanks!

Re: Strange line-spacing in headers? [SOLVED]

Going back to my original posting.

SUCCESS! 🙂

TL;DR; Use:

(custom-set-faces
 '(gnus-header ((t))))

Long version:

First I solved _one_ problem. After much poking, testing, and reading I
figured out that

info-gnus-english@cafax.se 2024-02-11 23:42 [+0100]:
> (custom-set-faces
>  '(gnus-header ((t (:inherit fixed-pitch)))))

actually took me to a different font than I expected. "Fixed-pitch" is
not my default font used in the article text*. If I told GNUS to use the
default font instead, the line spacing ended up correct. So _that_
problem was solved by using

(custom-set-faces
 '(gnus-header ((t (:inherit default)))))

So far, so good. But it came with a snag. (There is always one ... 😉)

Normally some words in the headers (e.g., sender's name and e-mail
address, other e-mail addresses, etc.) are shown in bold. Not so any
more. The color was correct, but not the weight and slant. I had to
figure out how to make that be inherited correctly from the respective
definitions.

Thanks to a typo I did, which brought me into the debugger, but with the
side-effect that the Article buffer came out as I wanted, I have now
come up with the following recipe that works for me. By setting the
property list to nothing, everything is set to "default", which somehow
makes all the pieces of the tetris fall into place. The property list
should thus be "(t . ())" = "(t . nil)" = "(t)", so here goes:

(custom-set-faces
 '(gnus-header ((t))))

I hope this helps some Googlers in the future.

Thanks for all help!

* I use a locally installed custom font as default. It's a variant of
  Courier called Courier Prime. (Really nice! Do try!) It took me a
  while to realise that fixed-pitch is coupled to regular Courier, which
  has a different line height. The two fonts are (to no ones surprise)
  difficult to distinguish, but Courier Prime is a little "fatter" and
  easier to read, IMHO.
