Re: guix installed Emacs

Alex,

thank you so much for your help

OK, this theme shouldn't cause the difference in brightness, I think.  I
have another guess.  Does Fedora use "site-start.el"?  If so, this file
is not loaded by Guix's Emacs, because it is placed somewhere in
/usr/share/... and Guix's Emacs doesn't look at this directory (also our
emacs uses its own "site-start.el" to load emacs packages installed in
"~/.guix-profile").

You can check if Fedora's Emacs uses "site-start.el" with this:

  M-x find-library site-start

Yes, the Fedora Emacs has this site-start

;;; loaded before user's ".emacs" file and default.el

;; load *.el and *.elc in /usr/share/emacs/site-lisp/site-start.d on startup
(mapc
 'load
 (delete-dups
  (mapcar 'file-name-sans-extension
          (directory-files
           "/usr/share/emacs/site-lisp/site-start.d" t "\\.elc?\\'"))))
(setq source-directory "/usr/share/emacs/24.5/")

and the Guix Emacs has

(require 'guix-emacs nil t)

 

But actually I don't understand how the difference in brightness can
happen at all.  This is a mystery for me.

You can move the point to 'variable-pitch' button and press RET there to
find out if it has the same customization in both cases.

This is the same for both Emacses

Face: variable-pitch (sample) (customize this face)

OK, so Fedora's Emacs has a bigger font (19 against 13).

You can use something like this to set the font and its size:

  (set-frame-font "DejaVu Sans Mono-15" nil t)

you were spot on on this ! In fact evaluating this line made the Guix Emacs window exactly equal to the one of the Fedora Emacs !

This should be fixed if you change the font size.

Right ! Even the minibuffer now is reasonably large and readable !

Another thing: I noticed that Guix's Emacs doesn't display some buttons
on the tool bar.  This should probably (I'm not sure) be fixed by
installing some icon theme in your profile, for example
'adwaita-icon-theme'.

I installed this adwaita thing but the icons keep not being there

Also the Fedora Emacs keeps being a bit brighter

But that's not that bad ! The showstopper was the tiny tiny minibuffer

And if that's a mistery to you, go figure what it is to me ;-)

Thanks for your help ;-)
