org-agenda-dim-blocked-tasks don't use org-todo face

org-agenda-dim-blocked-tasks don't use org-todo face

[Mark Kerr]

[-- Attachment #1: Type: text/plain, Size: 347 bytes --]

The org-todo face is used for todo keywords in non-blocked items.

When org-agenda-dim-blocked-tasks is set to true, however, the todo keyword
is instead displayed using org-agenda-dimmed-todo-face.

The org-priority face, however, is still used for blocked tasks.

Is this by design or due to an error on my part? Is there a possible
workaround?

This appears to be an omission on Org part, related some overlay
implementation details in Emacs.

Can you try the attached patch?

Subject: [PATCH] org-agenda-dim-blocked-tasks: Prioritize face over other
 overlays

* lisp/org-agenda.el (org-agenda-dim-blocked-tasks): Use high overlays
priority when adding dimmed face.  Otherwise, contained overlays, like
created by `org-agenda-fontify-priorities', will take
priority (default Emacs behavior).

This is my first time applying a patch, so I hope I did it properly.

Thank you. I may have been unclear but the result seems to be the
opposite of what I was hoping for.

I was hoping to be able to gain the ability to use the org-todo face
with blocked tasks, while retaining the org-priority face which was
previously working..

Now blocked tasks are entirely rendered with
org-agenda-dimmed-todo-face, including the priority.

In case I messed up the patch, here is the patched function:

--
(defun org-agenda-dim-blocked-tasks (&optional _invisible)
  "Dim currently blocked TODOs in the agenda display.
When INVISIBLE is non-nil, hide currently blocked TODO instead of
dimming them."                   ;FIXME: The arg isn't used, actually!
  (interactive "P")
  (when (called-interactively-p 'interactive)
    (message "Dim or hide blocked tasks..."))
  (dolist (o (overlays-in (point-min) (point-max)))
    (when (eq (overlay-get o 'face) 'org-agenda-dimmed-todo-face)
      (delete-overlay o)))
  (save-excursion
    (let ((inhibit-read-only t))
      (goto-char (point-min))
      (while (let ((pos (text-property-not-all
(point) (point-max) 'org-todo-blocked nil)))
      (when pos (goto-char pos)))
(let* ((invisible
(eq (org-get-at-bol 'org-todo-blocked) 'invisible))
      (todo-blocked
(eq (org-get-at-bol 'org-filter-type) 'todo-blocked))
      (ov (make-overlay (if invisible
    (line-end-position 0)
  (line-beginning-position))
(line-end-position))))
 (when todo-blocked
   (overlay-put ov 'face 'org-agenda-dimmed-todo-face)
            ;; Override other overlays.
            (overlay-put ov 'priority 50))
 (when invisible
   (org-agenda-filter-hide-line 'todo-blocked)))
        (if (= (point-max) (line-end-position))
            (goto-char (point-max))
 (move-beginning-of-line 2)))))
  (when (called-interactively-p 'interactive)
    (message "Dim or hide blocked tasks...done")))

Thank you, Mark

What you observe is what I intended to do.

What you want is an opposite of "dimming" (IMHO).

To achieve what you want, you may consider customizing
`org-agenda-dimmed-todo-face' face. This face is applied on top of all
other faces. If you, say, set only a background, the todo keywords will
retain their foreground colour.

I understand your viewpoint,  Ihor. Actually, it was mainly the font
size of the TODO keyword that I wanted to retain, not the colour.

The org-agenda-dimmed-todo-face overlay overrides the size set in
org-todo face, which breaks my layout.

I would like to retain the org-todo face colour as well, but it is
mainly the face size that causes me issues.

I have been fiddling with the face and overlay rules, but my knowledge
is not up to the task. From what I can tell, overlays always overwrite
faces.

I was thinking that a version of org-font-lock-add-priority-faces
could perhaps be adapted to work with todo keywords.

It should not, by default.
If it is, please try to reproduce the problem starting from emacs -Q, so
that I can see what is ha penning using my Emacs.

No, they do not. Overlays apply their faces on top of text properties
and on top of overlays with lower priority.

"On top" means that only face attributes that are "specified" are
overwritten. `org-agenda-dimmed-todo-face' only overwrites :foreground
by default.

Note, however, that your Emacs theme might change this. You can examine
the output of M-x describe-face <RET> org-agenda-dimmed-todo-face <RET>.
Pay attention to "Inherit", if any. The attributes of inherited faces
are also considered.
