[PATCH] Make the point visible when jumping to the mark

[Ian Kelling]

[-- Attachment #1: Type: text/plain, Size: 859 bytes --]

An example of the problem:

* headline-1
** one of many headlines I want to remain folded...
** headline
*** headline
The point starts here. I set a mark on this line.
Then I fold headline-1. This becomes invisible.
* headline-2
I move the point here. After I'm done here, I want to go back to my
mark. I do C-u C-space (pop-to-mark-command), but it doesn't go to the
mark. Instead, it takes me to the end of the still folded
headline-1. To get back to my mark without globally unfolding
everything requires tediously unfolding each headline and sub-headline
until the marked location is exposed.

There are some other non-org commands that would have this same
problem (isearch, bookmark-jump, save-place), but org-mode has code to
fix them. org-mark-ring-goto also handles this. I followed those examples
and wrote a patch. It is attached.

*lisp/org.el: Advise commands which jump to the mark
---

There are several non-org commands that jump to a location and would be
unwieldy if the location remained hidden, (isearch, bookmark-jump,
save-place), but org-mode has code to fix them. In this patch, I
followed their example.

I have an emacs fsf copyright assignment completed & on file with fsf, I can
send gpg signed copy if you need it.

I posted this patch in September. It seems it was forgotten. I posted it
again on April 30th, nothing yet. I also have another patch thats been
sitting on the list for a few weeks now after having a discussion and a
positive response. I'd like to do a git pull and find my patches applied
at some point, and I'm wondering if/when that will happen. And is there
anything I can do to help?

Yes, in http://article.gmane.org/gmane.emacs.orgmode/86050

Did you receive the FSF confirmation for your copyright assignment?
That's the information we need before applying the patches.

If the process is completed let us know and we will move on.

The formatting of the Changelog message not good.

It should be

* org.el: Advise commands which jump to the mark.

See http://orgmode.org/worg/org-contribute.html and example in
the git logs.

Why this one?  The user don't want to use C-SPC in hidden parts.

My mistake. Fixed in the attached patch.

Yes, I agree. They want to use C-u C-SPC to go to hidden parts. I've
updated the patch to advise pop-to-mark-command instead. It is attached.

Thanks, applied, I added a fullstop at the end of the Changelog commit.

As explain in my reply to Sébastien, I will move this code into a

Even if the goal is desirable, I thought that we may not add defadvice
in Emacs sources.

(... a couple of minutes later ...)

Well, Googling returns this :

  ╭──── http://www.gnu.org/software/emacs/manual/html_node/elisp/Advising-Functions.html
  │
  │ Emacs's own source files should not put advice on functions in
  │ Emacs. There are currently a few exceptions to this convention, but we
  │ aim to correct them.
  ╰────

So, it seems this should be avoided as long as Org does go into Emacs.

Best regards,
  Seb

True that, we need to clean things up.

The route I will take is to apply Ian patch on master and then to
move all advising code into a separate org-advice.el library in the
contrib/ directory.  Any suggestion for a better name?

I considered this problem when I made the patch, and originally started
writing it to not use advise. The alternative I see is to create
org-mode versions of these functions, and binding them with the
org-mode-map to override the existing functions, like we do with other
functions. I prefer advice in these cases because the advice is simple
and it is easier for users customizing keybinds and extending
emacs. However, compared to making it a module and thus not enabled by
default, I would prefer to make org-mode versions of the
functions. Having them on by default will be more helpful to more users
overall. I would be happy to write the patch for this, if we agree.

Anything that gets rid of advice is good, we agree on this.

If you have time, please start sketching out the patch so that we can
discuss how to replace some of the advice by internal Org functions.
Note that we will certainly hit some roadblocks, and we don't want to
replace core Emacs fonctions like `pop-to-mark'.

One possible outcome is to consider a new Emacs hook: something like
`after-interactive-point-move-hook' that would check if the current
buffer is in Org and would reveal the context systematically.

I haven't thought this through, but raising this needs on the
emacs-devel list will perhaps leads to something.

Otherwise, having a contributed package with advice (using
add-function instead of defadvice) would be good enough.

Thanks!
