Changing foreground colours for outline-minor-mode

Changing foreground colours for outline-minor-mode

[uzibalqa]

Having changed outline-regexp to accept ";;; H1" ";;; H2", ... as outline headers,
I also want to change the foreground colours at the different heading levels.

(defvar hglevels
  '( (";;; H1" . 1) (";;; H2" . 2) (";;; H3" . 3) (";;; H4" . 4)
     (";;; H5" . 5) (";;; H6" . 6) (";;; H7" . 7) (";;; H8" . 8) ))

(setq outline-heading-alist hglevels)

But I do not see the foreground colours taking effect.

Is the definition for hglevels wrong for setting outline-heading-alist ?

Would I need to enable outline-minor-mode before or after setting outline-heading-alist ?

Have you customized the outline-minor-mode-highlight variable? Have
you tried each of its possible values? After changing the variable,
did you re-activate outline-minor-mode?

(Also, what you’re trying to do is misguided, and if you’re doing that
as a library as you’ve hinted in other messages, then you’re harming
your users. For one thing, your modified patterns are suitable only
for languages that treat a semicolon as a comment starter, such as
Lisp; if applied indiscriminately to other languages, users will not
be able to add headings without breaking their language’s syntax.)

(Also, when you think of a possible improvement to a question that
you’ve asked earlier but that hadn’t received a reply, you should post
your improvement as a reply to that past question, not as a new
separate thread. That helps people review all the things you’ve said
in previous versions of the question.)

Yes, I have set it to 'override.  How does one re-activate outline-minor-mode,
using (outline-minor-mode 1) ?

I have started this as a test first on elisp files.

For me, the default outline headings in lisp (those starting with
three or more semicola or a ‘(def’) show up highlighted after I set
outline-minor-mode-highlight to 'override and do (outline-minor-mode
1). I have not tested with a custom outline-heading-alist.

I confirm that the default outline headings in lisp show up highlighted.
But not with a custom outline-heading-alist.
