font problems with the latest master in MacOS helvetia is used and not DejaVi Mono as in emacs28

font problems with the latest master in MacOS helvetia is used and not DejaVi Mono as in emacs28

[Uwe Brauer]

Hi

Finally I solved my problem in MacO10.15 and successfully compiled and
installed the current  master version.

However I am facing now a font problem. My entry in my custom-init file
is 
 '(default ((t (:inherit nil :stipple nil :background "grey98"
 :foreground "black" :inverse-video nil :box nil :strike-through nil
 :overline nil :underline nil :slant normal :weight normal :height 160
 :width normal :foundry "PfEd" :family "DejaVu Sans Mono"))))

Now indeed in emacs28 C-u C-x = gives 
,----
|              position: 2303 of 64364 (4%), column: 23
|             character: C-j (displayed as C-j) (codepoint 10, #o12, #xa)
|               charset: ascii (ASCII (ISO646 IRV))

|

However when I start emacs29 helvetica is used which is a proportional
font, and looks terrible in most circumstances, especially in dired

Here is what C-u C-x = 
gives

,----
|              position: 54 of 1045 (5%), column: 53
|             character: C-j (displayed as C-j) (codepoint 10, #o12, #xa)
|               charset: ascii (ASCII (ISO646 IRV))
| code point in charset: 0x0A
|                script: latin
|                syntax:   	which means: whitespace
|              to input: type "C-x 8 RET a" or "C-x 8 RET LINE FEED (LF)"
|           buffer code: #x0A
|             file code: #x0A (encoded by coding system undecided-unix)

| 
| Character code properties: customize what to show
|   old-name: LINE FEED (LF)
|   general-category: Cc (Other, Control)
|

Who is the culprit here?
What shall I do?

Thanks

What happens if you remove all the attributes except :family and
colors?

Do you  mean
(custom-set-faces
 '(default ((t (:inherit nil :stipple nil :background "grey98"
 :foreground "black" :inverse-video nil :box nil :strike-through nil
 :overline nil :underline nil :slant normal :weight normal :height 180
 :width normal :foundry "PfEd" :family "DejaVu Sans Mono")))))

To 

(custom-set-faces
 '(default ((t (:inherit nil :stipple nil :background "grey98"
 :family "DejaVu Sans Mono")))))

Does not help.

When I start customize-face
select default, I see helvetica, I change that to DejaVu Sans o DejaVu
Sans Mono
press apply and nothing happens, no visible change.

But in emacs28 it works perfectly.

What about starting Emacs as

  emacs -fn "DejaVu Sans Mono"

?

Does not work neither.

emacs -fn "DejaVu Sans Mono" -q 

However does work. So something is odd here in 29, while it works in 28.

When I run 

 customize-faces
 default
 return 

I see, so Helvetica is set, but I cannot change this setting, I mean I can change the name to DejaVu Sans Mono but it has no effect. 

This looks like a bug of sorts to me.

I also happens when I start emacs29 -q 
the default font is Helvetica and that cannot be changed neither via the customize-faces nor via the options-->set-default-font

I think I sent a bug report.

This suggests that something in your customizations interferes.

But if start emacs -Q then Helvetica is already selected and cannot be changed!

That is master specific and does not happen with emacs28 or 27.

Could Lars change (from several weeks ago) concerning proportional fonts
have something to do with it?
