ANN: org-sticky-header

[Adam Porter]

Hi friends,

I've posted another package which you might find useful:

https://github.com/alphapapa/org-sticky-header

It's modeled on semantic-stickyfunc-mode.  When you scroll down and push
an Org heading out of view, it displays that heading in the Emacs header
line at the top of the window so you don't forget which heading the
partially displayed entry at the top belongs to.

It seems to be working well so far.  Please let me know if you have any
feedback.

Thanks,
Adam

I love it! I've wanted something like this for long text files for ages
-- this scratches a very old itch. Thanks for doing this, and I'll
report back with issues, though it's work great so far.

Interesting and seems to work well overall.  One minor point: for some
reason, the contents of the header line are shifted to the right by one
character so there's a little dissonance.  I use org-indent-mode in case
that matters.

Hi Adam,

this is great, I love it!

I am wondering if you would consider the possibility to show on only the
most recent heading, but, space permitting, the outline path - maybe in
reverse order as to keep the sticky heading itself in the left-most column.

Something like

*** current level | ** level above | * top level

you could use `org-get-outline-path' to get the other headings up the tree.

I don't necessarily think it should be the default, but it could be an
option.

Cheers

Carsten

P.S. I also see what Eric Fraga is seeing and would love to have this issue
solved.

Re: ANN: org-sticky-header

Indeed, very cool!

The spacing seems to come in here:

(defun org-sticky-header--fetch-stickyline ()
  "Make the heading at the top of the current window sticky.
Capture its heading line, and place it in the header line.
If there is no heading, disable the header line."
  (save-excursion
    (goto-char (window-start))
    (unless (org-at-heading-p)
      (org-back-to-heading)
      ;; TODO: 3 spaces seems to be almost right, but it's still not
      ;; perfect, and it's probably not universally right.  Something
      ;; related to org-indent might be good.
      (if org-sticky-header-full-path
          (org-format-outline-path (org-get-outline-path t) nil "   ")
        (concat "   " (buffer-substring (line-beginning-position)
  (line-end-position)))))))

Maybe the three spaces should be stored in a defcustom. I like no spaces
personally.

On that note, there is also org-eldoc.el in contrib/ that sort of does what
you want.

"sort of" because:

- Shows the breadcrumbs in the echo area instead of in header.
- Shows that only when point is on an org heading, not when in the body.

It is indeed but it would still be nice to have it in reverse order, as
you suggested in an earlier post.  My top level headline overwhelms the
header...

I really liked it. I'm editing a huge document and it helps a lot having

That's a great idea, I will add that.  Thanks.

Thanks, Eric, I'm glad it's useful for you.  :)

Re: ANN: org-sticky-header

[Adam Porter]

Thanks for your feedback, everyone.  I've just pushed some updates that
add options for the prefix and reversing the path display.  Please let
me know if you have any other ideas or issues.

Hi Eric,

Oops, for some reason this message wasn't threaded and I missed it.

I was using three spaces, which looked okay on my system, but I'm sure
it didn't look right on everyone's.  I added an option to configure it
now.  It would be nice to calculate it automatically somehow, but this
should be an improvement.

[-- Attachment #1.1: Type: text/plain, Size: 1064 bytes --]

Hi Adam,

thanks for adding the option to reverse the outline path.  Great thinking
about using a different separator for the reversed path!

It mostly works - however, if the window is too narrow, the abbreviation
ellipses are now applied to the most recent heading instead of to the last
one shown.  It would be better to reverse the outline path before sending
it into org-format-outline-path, which also saves you the pain to split and
rejoin the path string.

Please find attached a patch that makes this change.  It also removes the
dependence on the string library which is, I think, not by default
available in Emacs.

Thanks

Hi Adam,

and just after I send this, I now see that the faces of the headings
in the path are now wrong - so you probably already had gone down
this path.  Sorry for the noise, need to come up with something better.

Excellent.  Thank you.

One other minor issue: if there are any inline tasks, the sticky header
shows "END" if there is such an inline task not in the window but
between point and the previous headline.  I think that if point is not
within an inline task, you should be skipping inline tasks (my own
preference) or displaying the headline for the task and not the END
line.

Thanks again,
eric

That would be hard to implement.  Skipping inline tasks entirely would
be easy enough, just truncate the list of path entries to below
org-inlinetask-min-level.

Thanks, Eric and Carsten.  I'll look into this soon.

Thanks, Carsten, I will work on this soon.

This should now be fixed.  Thanks!

I have encountered a bug when trying to export a subtree containing an 
inlinetask just after the headline/metadata and a src block further down.

Here is an ECM:

--8<---------------cut here---------------start------------->8---
* a Headline
*************** my task

   Do this well!

*************** END

#+NAME: my-model
#+BEGIN_src latex :results latex
   \begin{displaymath}
     y = x + z
   \end{displaymath}
#+END_src
--8<---------------cut here---------------end--------------->8---

Put the cursor under the headline (at the end of buffer, say) then type

C-c C-e C-s l L y

and without org-sticky-header mode you get an exported buffer.

With org-sticky-header mode, it just hangs after the 'y' is typed.

Also, if you put point at the beginning of the second line (the start
of the inlinetask) and type

: M-: (narrow-to-region (point) (point-max))

it will narrow if o-s-h mode is off, but hang if it is on.

Adding a newline after the headline `cures' the export problem.
However, if point is at the start of an inlinetask, then emacs will
hang when running the narrow-to-region snippet above regardless of
newlines.

p.s. I am using commit b82b4f210e... (newest at this time)

Infinite loop with org-inlinetask and org-sticky-header [was Re: ANN: org-sticky-header]

[Adam Porter]

Hi Charles,

Thanks for reporting this.  This is bizarre.  I reproduced it with my
personal config, and with "emacs -q", but it only happens if
org-inlinetask is loaded with "(require 'org-inlinetask)".  This is with
Emacs 25.1 and the Org package distributed with it for "emacs -q", and
with Emacs 25.1 and Org 9.0.5 on my personal config.

I used "pkill -SIGUSR2 emacs" to interrupt the infinite loop and get a
backtrace, but it took many tries of running that command in rapid
succession, because each time, "Entering debugger..." would flash in the
minibuffer for a moment before the process would go back into the
infinite loop.  After enough tries, it would stop the loop and show the
backtrace, but it would go back into the loop as soon as I tried to
switch windows or paste the backtrace into another program.  I had to
kill the process to make it stop.

I'll paste below two backtraces I managed to get, but I'm afraid I don't
know where to go from here.  Since it only happens if org-inlinetask is
loaded, I guess it's not a bug in org-sticky-header per se, but a bug
that org-sticky-header exposes somehow.  Aaron Jensen actually uncovered
a bug in Emacs itself, and in org-sticky-header, a few days ago:

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=26586

It was also an infinite loop.  It seems unlikely to me that it's the
same bug, but maybe they are related somehow.  It's all I have to go
on.  If you are interested and adventurous enough, you could try
building Emacs with the fix mentioned on that bug report, and see if you
can still reproduce it.

I can't be sure that it's actually a bug in Emacs, but since the
infinite loop is practically impossible to break out of without killing
the process, and since these backtraces don't mention anything related
to org-anything, it seems like it should be reported as an Emacs bug.
