bug#42184: 27.0.91; org-fontify-whole-heading-line does not work in emacs 27

[Erik Hetzner]

[-- Attachment #1: Type: text/plain, Size: 656 bytes --]

Setting `org-fontify-whole-heading-line' and `org-fontify-whole-block-delimiter-line' does not give a background color to the entire line in emacs 27. It works in 26.3 (although the latter variable is not present).

To reproduce, evaluate:

(require 'org)
(setq org-fontify-whole-heading-line t
      org-fontify-whole-block-delimiter-line t) ;; omit in emacs 26
(load-theme 'leuven t) ;; uses a colored background for org headings

Then open a simple org file, e.g.

* Hello world
** test
#+begin_src
#+end_src

In emacs 26.3, the entire heading line (and block delimiter) has a background color. In emacs 27, this is not the case.

With the attached diff against leuven, running

I don't know if patching leuven is TRT?  Maybe the :extend t should be
added to the face definitions directly, since Org provides a knob
(org-fontify-whole-heading-line) to control whether the final newline is
fontified?

Yes, I think the change should be in Org, not in the themes.

OK.  Paging in Nicolas and Bastien (I don't know who exactly should join
in on our fun, or if I should just cross-post to emacs-orgmode@gnu.org).

Have the Org maintainers given some thought to what should become of
org-fontify-whole-heading-line and
org-fontify-whole-block-delimiter-line from Emacs 27 onward?

If these options still make sense (i.e. users should be able to choose
between extended or non-extended backgrounds/under/overlines,
independently of how themes customize the faces), org-level-* and
org-block-{begin,end}-line should probably be defined with :extend t?


Relatedly (but not crucial to solving this bug), should org-block and
org-block-background also have :extend t?  It would make sense to me
since they delimit visual "blocks".


Last question (that one might be answered somewhere in Org's
documentation): how should we patch org-mode?  First on emacs-27, then
on org-mode's maint branch?

To make the discussion more concrete: here's a suggested patch for Org
against the emacs-27 branch; what say you?

My aim was to allow you (Org maintainers) to commit this verbatim to the
org-mode repository, where you probably want to keep supporting Emacs
≤26.3.

NB: I'm far from an Elisp wizard, there may more elegant ways to solve
this than my backquotefest; suggestions welcome.

I still think the answer to the above is "yes".  Will add to my patch if
you agree.

I don't understand why you extend all those faces: the original report
was about a much smaller set.  It is not the intent that every face
that happens to span the entire line be extended: that's why we made
':extend' by default be off for a face.

What am I missing?

The original report was about the org-level-1 and org-level-2 faces, as
well as org-block-begin-line and the org-block-end-line.

The only faces I added were org-level-[3-8], because I don't see why
different heading levels should not work with
org-fontify-whole-heading-line.

AFAICT, this is the simplest way to fix org-fontify-whole-heading-line
and org-fontify-whole-block-delimiter-line for Emacs ≥27.  These user
options work under the assumption that simply fontifying the final
newline is enough to extend attributes past EOL.


The long term fix might be for Org to (1) deprecate these user options
and let themes and/or users apply :extend t themselves, or (2) slap
:extend t onto the faces when setting up the major mode fontification
depending on these user options (Org already does similar on-the-fly
face tweaks; see e.g. org-hide).  Or something else.

It seems to me that this kind of change would be somewhat more involved
and breakage-prone, but if Org maintainers think this is the way forward
for emacs-27, I wouldn't mind.

Yes.  So I'd expect to see the respective faces have the :extend
attribute under each one of the 2 options cited in the original
report.

The original code only affects certain heading levels, it doesn't
affect all of them.  So I see no need for any "consistency" here.

More generally, the :extend attribute is by default off because we
want most of the faces not to be extended.  Let's only extend the
minimum, not anything that could be extended in principle.  Which is
another aspect of your proposed patch I'd like to change: it seems to
cause these faces be extended unconditionally, not just under these
optional variables.  Or did I miss something?

Nevertheless, I would like to see the :extend attribute applied only
under the above options; there's the set-face-extend function for
doing that.

I don't see why these options should be deprecated, and even less why
the faces should have the :extend attribute.  It would go against the
intent behind introducing that attribute in the first place.

Thanks.

By "the original code", you mean this part in
org-set-font-lock-defaults, right?

That seems to apply to all heading levels to me?  Group 1 captures all
but the last stars, group 2 the last star, and group 3 the heading text?

IIUC, org-fontify-whole-heading-line (which predates :extend t) is Org's
way of letting users "opt in" to face extension, by applying the
org-level-* face to the final newline *iff* this user option is set.

Adding :extend t to the face definition thus will not cause the
backgrounds to extend unconditionally: as long as the user option is
unset, the final newline will not be fontified.

OK.  That's more or less what I had in mind when I went into my
"long-term fix" ideas.

Note that Org tries to support older Emacs versions.  AFAICT, with my
patch, (1) org-fontify-whole-heading-line is fixed for Emacs 27, (2) no
further modification is needed for Emacs ≤26.

I can try to cook up a patch based on set-face-extend instead, with all
the fboundp fun that entails to prevent byte-compiler warnings with
older Emacs versions.  I'm not sure where the calls to set-face-extend
should be inserted; when setting up the major mode?

At this point, I should probably wait for Org maintainers to chime in…

Since all the other threads I'm following are stalled, I've taken a stab

While it fixes the issue, I don't know if it's the cleanest way to do it
(repeatedly calling set-face-extend on the same faces every time an Org
buffer is opened/reverted seems a bit silly).


Also, while this is not part of the report because Erik's example
happens not to have any text between the block delimiters (#+begin_src
and #+end_src), I would like to re-emphasize that I'm pretty sure
org-block (and maybe org-quote and org-verse) should be defined with
:extend t unconditionally, to maintain the "rectangular" aspect the
blocks have in a browser once exported to HTML:

If people agree, I can make at patch similar to bug#42184#17 for those
faces only.

Here is a variant of the previous patch, which correctly resets :extend
to nil if the user disables the relevant options (after reverting the
current buffer, or for newly opened ones).

This ends up looking similar to what Org does for org-hide; IMO this
seems like the most straightforward short-term fix.  In the long run,
these user options would probably deserve :set functions.

Thanks for working on this fix.  I of course can't speak for Bastien or
Nicolas, but this patch looks fine to me.  Assuming it's okay with Eli,
I'd suggest applying it to the emacs-27 branch.  (Once applied, I'd port
it to the Org repo, as I do with other changes in the Emacs repo that
touch Org files.)

That would make sense to me as well.  (org-block-background hasn't
existed since v8.3, though.)

Thank you for the review.  I hope this can make it into 27.1 since this
bug seems to be getting some attention[1][2], but the (tentative?)
etc/HISTORY file on the emacs-27 branch makes me wonder if we aren't too
close to the release day…

It's too late for Emacs 27.1, and in any case I'd like to hear the
blessing of Org developers before installing this.  (I'd expect this
to be first installed in Org and then in Emacs, not the other way
around, but if it's okay with the Org folks to do it otherwise, I
won't object.)

The fix has been installed in Org and will be available for Org 9.4,
which we hope to release very soon.  So I'm closing this report now,
unless this is bad policy to close the bug report before it is fixed
in Emacs.

It is okay to make fixes to Emacs Org then to backport them to Org
maint branch, but since it is additional work, we prefer fixes to go
directly to the maint branch, before we merge it into Emacs.

Speaking of Org's maint branch (where the fix has been applied), are
there plans to synchronize it with the emacs-27 branch, so that Emacs
27.2 benefits from all the fixes to the 9.3 release?

As the person primarily doing that porting for quite some time now, I of
course don't disagree with that.  My suggestion was in the context of
hoping to get the change into Emacs 27 at a point when a full Org sync
was not going to happen.

Thank you.

IMO, it is highly preferred that you routinely close Emacs bugs related
to Org mode when you have fixed them on your end.  We only need to track
that the bug has been handled in a satisfactory manner.

If the maint branch contains only bug fixes, why shouldn't we?

Eli will explain what he prefers, but I would propose to open a new bug
report to track it, and we can mark it as blocking for the Emacs 27.2
release.  That way there is less risk of forgetting about it when it's
time to make the next point release.
