How to reload a custom color theme to pick up changes?

[ericsoderstrom]

I'm modifying a custom color theme, using custom-theme-visit-theme
After making changes to some faces, I can't get the changes to be picked up by emacs without full closing and restarting the program.
I've tried disable-theme into load-theme and doom-reload-theme and doom/reload
But nothing seems to pick up the color changes aside from a full restart.

EDIT: The fix is up: doomemacs/core@1aabae7

Turns out there is a bug in doom/reload where it doesn't re-evaluate the theme's source file, in case of changes. I'll push a fix for that soon, but in the meantime you can fix it locally with:

;;; add to $DOOMDIR/config.el
(defadvice! fixed-doom/reload-theme ()
  :override #'doom/reload-theme
  (interactive)
  (let* ((themes (copy-sequence custom-enabled-themes))
         (real-themes (cl-remove-if-not #'doom--theme-is-colorscheme-p themes)))
    (mapc #'disable-theme themes)
    (dolist (th (reverse themes))
      (if (locate-file (concat (symbol-name th) "-theme.el")
                       (custom-theme--load-path)
                       '("" "c"))
          (load-theme th t)
        (enable-theme th)))
    (doom/reload-font)
    (message "%s %s"
             (propertize
              (format "Reloaded %d theme%s:"
                      (length real-themes)
                      (if (cdr real-themes) "s" ""))
              'face 'bold)
             (mapconcat #'prin1-to-string real-themes ", "))))

Otherwise, some ways that seem to get around the issue are:

• In the custom-theme-visit-theme UI, click "revert" after clicking "save theme".
• Or save the theme under a new name, not the same as the old theme, then M-x load-theme RET new-theme-name should work.
• Or call load-theme with a non-nil second argument M-: (load-theme 'name-of-theme t). This forces it to reload the theme's source.
