Determining font weight

Determining font weight

[goncholden via Users list for the GNU Emacs text editor]

Is there a way to determine the font weight resulting from the command

(set-face-attribute 'default nil :height 160 :weight 'ultra-bold)

`face-attribute' or `get-char-property' ... maybe.

I am changing font-lock-comment-face to normal weight.

(set-face-attribute 'font-lock-comment-face nil :weight 'normal))

But want to be able to change it back again to the default setting done initially
using

(set-face-attribute 'default nil :height 160 :weight 'ultra-bold)

The problem is that I would not know what weight was used in the user init
file, so I got to capture the weight (you mentioned face-attribute). But I
do not know  hon to use to set the comment face back to the original weight.

I would use (face-attribute face :weight), however what face should I use? so that
I con reset the weight of font-lock-comment-face?

This is probably what you want.  Please note additional optional
attributes in face-attribute function.

;; Store initial width
(setq initial-weight (face-attribute 'font-lock-comment-face :weight nil t))

;; Change face width
(set-face-attribute 'font-lock-comment-face nil :weight 'bold)

;; Restore face width
(set-face-attribute 'font-lock-comment-face nil :weight initial-weight)

If your issue is related to the thread “Adding functionality to a minor
mode”, then I think you are mistaken.

Why define a minor mode to modify the syntax highlighting normally
defined inside a major mode using Font Lock mode?
