[ANN] Org mode 9.7 is out

[ANN] Org mode 9.7 is out

[Ihor Radchenko]

Dear all,

Org 9.7, a major release, is out.
Org 9.7 will be a part of Emacs 30.

You can upgrade from GNU ELPA or install with M-x package-install RET org RET

Please, also re-install all the Org-related packages - some of the
changes require re-compiling packages that use Org mode APIs.

Org 9.7 added a number of new features and customizations, all listed on
<https://orgmode.org/Changes.html>.

If you enjoy using Org, please consider supporting contributors via
<https://liberapay.com/org-mode/>. Donations do help a lot.

* Some highlights of user-facing additions

- Org mode supports drag-and-drop and pasting images/files from
  clipboard (pasting from clipboard requires Emacs >=29)

  Thanks to Visuwesh for contributing these features.

- id: links support search options like [[id:my-id::*child heading]]:
  Any valid fuzzy location will work as a search option.

  Contributed by Rick Lupton.

- Org mode honors ~display-buffer-alist~ settings for window placement

- Shell code blocks support asynchronous evaluation

  Contributed by Matthew Trzcinski, the new ob-shell maintainer.

- iCalendar export now handles recurring tasks

  Contributed by Jack Kamm, the new ox-icalendar maintainer.

- Face background in folded headings and blocks can extend to the right
  margin.  This is a small, tricky, but widely requested feature.

- Moving, promoting, and demoting headings/items honors region.

  You can now conveniently select multiple headings/items and use, for
  example, =M-<down>=/=M-<up>= repeatedly without losing the selection.

* Important changes in Org parser

Library authors and Elisp hackers, please pay attention to major changes
of Org parser API:

1. Parser uses lazy evaluation by default, for speed

2. Many Org mode functions can accept parser objects (or return value of
   `org-element-at-point' as arguments)

As a result of these changes, internal representation of Org parse tree
has been changed. Please use Org element API to access element/object
internals. All the details in <https://orgmode.org/Changes.html>.

* Development updates

I would also like to welcome new maintainers of Org mode libraries:

- Daniel Kraus is maintaining ob-sql and ob-clojure
- Matthew Trzcinski is maintaining ob-shell
- Jack Kamm is maintaining ox-icalendar (in addition to ob-python that
  he has been maintaining for the last 4 years)

We are still looking for additional maintainers of individual Org
libraries, especially ox-latex and ox-html. More than half of all the
Org libraries currently do not have any dedicated maintainer. Please
consider volunteering. See
https://orgmode.org/worg/org-maintenance.html#maintainer-role for more
details. Maintaining takes less effort than one may expect (see the
link).

That’s great!

What happens when I paste an image?

I wish I could join (I use both ox-latex and ox-html in
hobby-but-for-me-personally-critical tasks), but I’m already
overstretched.

Deepest thanks to all current maintainers for your great work!

Best wishes,

The image will be saved with automatically generated name near Org file
(or as attachment) and the link to the image will be inserted. Try it
and see.

All the aspects are configurable:
- org-yank-image-save-method
- org-yank-image-file-name-function
- org-yank-dnd-method
- org-yank-dnd-default-attach-method

I'm on a Mac (M1 MB Air, Ventura).

GNU Emacs 29.3 (build 1, aarch64-apple-darwin22.6.0, NS appkit-2299.77
Version 13.6.5 (Build 22G621)) of 2024-03-24

When I drag and drop a jpg image to an Org buffer, Emacs opens the image
i new buffer, not in the Org buffer.

When I copy the jpg file in Finder and paste it C-y to the Org buffer,
the file name appears. No org syntax for including an image is added.

Is there anything else I have to do?

Last, but not least: Thanks to everyone in the team for Org 9.7!

Regards,
Jürgen.

Interesting.
May you try M-x debug-on-entry RET dnd-open-local-file RET
Then, drop an image, and share the backtrace displayed?
(after getting the backtrace, you can cancel interruption via M-x cancel-debug-on-entry)

Yes, you need to use M-x yank-media, not C-y.

Thank you, this indeed did the trick. Now, Org created an attachment,
but not the original jpeg was added. Instead org added a tiff file in a
subfolder of the org file working directory. However, I cannot open it
in Preview as a tiff file.

Looks like Mac does not follow XDND.
I think I know how to fix this.

Org normally asks you what format to insert, if multiple formats are
available from clipboard.

That's questions to firefox/preview. But I think that you should simply
select a different format when pasting. tiff is not the most widely
supported format.

Well, the image I used is this one. It was available because I had
downloaded it the other day:

https://www.europeana.eu/fr/item/2021012/_42FFE0B5C39B7F9819D6D3692B2F4154

The format is jpg. I have no idea why I get a tiff attachment when I try
to include a local jpg file. Maybe the macOS clipboard offers several
formats and Emacs/Org choses one option because it is offered first or
for some other reason? Or some kind of conversion plays into this on the
system level when copying to Emacs? Or there is something wrong or
unsusual with the jpg file, perhaps it was a tiff file in the first
place, later converted to jpg. I do not know.

There is one more thing: My Emacs init time has got slightly longer
since updating to Org 9.7.1 from ~1.9 to 2.273441 seconds. I
re-installed Org and the depending packages, as you recommended
(org-contrib, org-static-blog). No more changes, same setup as before.

@Christopher, thanks for your suggestion, I'll have a look if it fits
into my init file when I rework it mid summer.

Regards,
Jürgen.

Even Linux clipboard offers several formats if I copy from browser.
After M-x yank-media, I get "Several types, available, choose one:"
prompt, with options to choose from png/pbm/xbm/xpm/jpeg format. I
guess it is also tiff in your case. Just choose another format in that
prompt.

As it usually goes with the config, it can be anything.
Use profiler to reveal the cause.

One blind guess could be that Org mode loads more built-in libraries
(like yank-media library) now. So, loading might be slower. Not sure
about 0.4 seconds slower.

In future versions, I have a plan to rework the way Org mode loads,
aiming for faster load times among other things. (this is annoyingly
difficult task; like 300+-commits-and-no-end-in-sight level annoying)

I'm afraid I forgot to mention that I don't get prompted, and I did not
copy the image from my webbrowser. Rather, I downloaded the jpg file
over Europeana's proxy from Finnish National Library and then copied
this one with Command-c in Finder (the macOS file manager) from local
system SSD. I do not understand how the tiff comes in here. But is is
there in the data folder Org created. I tried to open it in Preview, I
even changed the file ending to .jpg, but I cannot open it. The tiff
file seems to be corrupt.

No need to worry about that.

Please tell what is shown in the *Completions* buffer when you do M-x
yank-media-types RET after you copy the image to the clipboard.  I
suspect the problem is with the regexp used to detect the mime-type.

Sorry for my late reply. I have updated to Org 9.7.2 in the meanwhile.

M-x yank-media-types RET yields:

Yank type:
clipboard:image/tiff
clipboard:STRING
clipboard:text/plain

M-x yank-media RET still inserts an attachment with a tiff file that I
cannot open in Preview.

BTW, Org identifies with a rather longish string that used to be shorter
in Org 9.6:

Org mode version 9.7.2 (release_N/A-N/A-88dd2c @
/Users/juergenfenn/.emacs.d/elpa/org-9.7.2/)

I'm afraid there's nothing much we can do.  IIUC, you copy the file from
a file manager, so Org expects clipboard to be something like

    Possible completions are:
    clipboard:x-special/gnome-copied-files
    primary:...

where clipboard:x-special/gnome-copied-files gives

    copy
    file:///home/viz/tmp/2-gnus_stipple.png

but given there's neither image/jpeg nor a special type like the above,
Org's yank-media copies the image/tiff data (the regexp used by Org
looks for mime-types that match the regexp "image/.*").
I am guessing clipboard:text/plain contains the link to the file, am I
right?  But this feels fragile to rely on.

What happens when you copy multiple images to the clipboard from the
file manager?  Is there a difference in yank-media-types' output?  What
if you copy a non-image file to the clipboard? Say a PDF file.

I don't have access to a Mac but if you can find documentation on how
Finder puts the relevant data in the clipboard, that would be useful.
[ In Linux, you expect the x-special/gnome-copied-files or somesuch
  TARGET.  ]

BTW, we might have similar problems in Windows too.  See this thread in
emacs-devel when yank-media was initially added:
https://yhetil.org/emacs-devel/837ddk9tc8.fsf@gnu.org

> M-x yank-media RET still inserts an attachment with a tiff file that I

Given the above, I hope you understand why this happens.

HTH.

Looking at that thread, I see

+  /* Dictionary for looking up NS types from MIME types, and vice versa.  */

+             nil];

For images, only image/png and image/tiff are listed for some reason. No
jpeg. (and no jpeg in the spec at
https://developer.apple.com/documentation/appkit/nspasteboardtype)

I suspect that image/tiff entry in the clipboard is garbled by Emacs.
We may want to report this as a bug.

We may also need to request a feature to support clipboard on MacOS
better. Using the same example image.

If I copy Command-c two different jpg files in Finder, Org seems not to
be able to process any file. There is only

clipboard:STRING
clipboard:text/plain

in the completions buffer, no image MIME type.

When I try M-x yank-media RET I get the message:

user-error: No handler in the current buffer for anything on the clipboard

But it is getting even more weird when I try a different MIME type, say
PDF, as you suggested. I've just tried the latest LaTeX News 39 which
happens to be on my desktop. It has not been published yet, but you can
easily compile it yourself from
<https://github.com/latex3/latex2e/blob/develop/base/doc/ltnews39.tex>.
Copy with Command-c from Finder, then M-x yank-media RET also yields:

clipboard:image/tiff
clipboard:STRING
clipboard:text/plain

While M-x yank-media RET yields:

----
* Test
:ATTACH:
:PROPERTIES:
:ID:       105A314B-BCA8-41CC-8ED8-FA97F70AAE85
:END:

[[attachment:clipboard-20240605T174306.tiff]]
-----

and now I am indeed prompted for the =Yank type= from the three options
above. I can select with Cursor-up or Cursor-down.

- If I select image/tiff the PDF is added in plain text, it seems.
- Selecting STRING simply pastes the filename =ltnews39.pdf= to buffer.
- Selecting text/plain pastes the path to the file to buffer.

I'm afraid I cannot provide this information because I am not a
developer, so I don't know which documents to consult for this.

I just would like to add that such internals in macOS may change over
time. I'm on Ventura, which is not the latest version of macOS, that's
Sonoma. Its successor macOS 15 will probably be released in a few
months. Even the way self-compiled Emacs is run are said to vary from
one version to another. I cannot tell because I did not compile Emacs
before I switched to Ventura, but I trust such reports are true.

Regards,
Jürgen.

Thanks for the analysis.  Given that Alan says GNUStep cannot handle
non-text clipboard items, I cannot propose anything myself.  It would be
nice if a Mac user can write a report and send it to the Emacs
developers.  Perhaps Juergen can do it?

There was a bug report about yank-media failing in Mac yesterday or
thereabouts so I think the clipboard situation in Mac has a lot to
improve.  Hopefully with Org's yank-media support the situation will
improve.

Of course, I /could/ do this, but given the fact that you have already
found out about /some/ internals wouldn't it be better a macOS/NextStep
developer would look into this in the first place and hence write the
report with some somre insight?

Unfortunately, there are no MacOS developers among Org mode maintainers.
I personally do not even have access to MacOS for testing.

Since you at least can test things on MacOS, it would be helpful if you
can create the recipe suitable for Emacs devs to reproduce the
problem. They may also ask extra information from your MacOS.

I see. Thanks for explaining. So, I will write a bug report that draws
on our discussion and send it to emacs-devel over the weekend.

My switch from Ventura to Sonoma shortly may make things more
complicated, as I cannot foresee in howmuch the two platforms differ
under the hood, but I'm afraid I cannot postpone the upgrade.

Jürgen.

A few years ago, I wrote a small package for pasting PNG and PDF into org documents as attachments, which I still use: org-mac-image-paste:  https://github.com/jdtsmith/org-mac-image-paste. 

With the recent work on yank-media I'm hopeful I can retire this tool soon (see the bottom of that page).  I found I could pull PDF data from the clipboard via AppleScript (and display in the emacs-mac build using its image-io backend), but had to use the pngpaste tool for PNG data.  PNG data are indeed included on the clipboard («class PNGf»), and can be seen via AppleScript.

The code for pngpaste might be informative: https://github.com/jcsalterego/pngpaste/blob/main/pngpaste.m.

A few years ago, I wrote a small package for pasting PNG and PDF data from the Mac clipboard into org documents as attachments, which I still use:  https://github.com/jdtsmith/org-mac-image-paste. 

With the recent work on yank-media I'm hopeful I can retire this package soon.  I found I could pull PDF data to file from the clipboard via AppleScript (and display in the emacs-mac build using its image-io backend), but used pngpaste[1] tool for PNG data.  When an image is on the clipboard, PNG data are indeed available from the clipboard («class PNGf»), as can be seen via AppleScript.  You can use AppleScript to inquire about the state of the clipboard.  For example, after taking a screenshot, I see:

% osascript -e "clipboard info"
«class PNGf», 121849, «class 8BPS», 401974, GIF picture, 21636, «class jp2 », 21831, JPEG picture, 35062, TIFF picture, 369790, «class BMP », 366218, «class TPIC», 285265

On copying an image from a website, I get:

% osascript -e "clipboard info"
TIFF picture, 91686, URL, 81, «class urln», 6, «class utf8», 81, «class rtfd», 2652, «class weba», 5679, «class HTML», 800, «class 8BPS», 103154, GIF picture, 681, «class jp2 », 5455, JPEG picture, 1059, «class PNGf», 6282, «class BMP », 44298, «class TPIC», 8066, «class ut16», 164, string, 81, Unicode text, 162

For images grabbed from web-pages, you can actually get the URL information if you like and include that in or near the attachment link.  

Here's after copying a GIF file from the Finder:

% osascript -e "clipboard info"
«class furl», 41, «class ut16», 24, «class utf8», 11, «class icns», 1137764, Unicode text, 22, string, 11, «class 8BPS», 1295026, GIF picture, 74698, «class jp2 », 110628, JPEG picture, 62209, TIFF picture, 4198020, «class PNGf», 305211, «class BMP », 4194442, «class TPIC», 796024

Notice the file-URL there, which you can get (here using the JXA=javascript flavor of AppleScript, with a UTI for the file-url, which is apparently the more modern way to do it):

% osascript -l JavaScript -e 'ObjC.import("AppKit"); $.NSPasteboard.generalPasteboard.stringForType("public.file-url");'
file:///Users/xxyz/Desktop/output.gif

You can even coerce the clipboard to be in a certain format:

% osascript -e "clipboard info"
TIFF picture, 35766, URL, 37, «class urln», 7, «class utf8», 37, «class rtfd», 1082, «class weba», 3643, «class HTML», 820, «class 8BPS», 9884, GIF picture, 434, «class jp2 », 4617, JPEG picture, 1268, «class PNGf», 1527, «class BMP », 32538, «class TPIC», 2446, «class ut16», 76, string, 37, Unicode text, 74

% osascript -e "set the clipboard to (the clipboard as JPEG picture)"

% osascript -e "clipboard info"                                      
JPEG picture, 1268, «class 8BPS», 8622, GIF picture, 687, «class jp2 », 4671, TIFF picture, 27704, «class PNGf», 2508, «class BMP », 24534, «class TPIC», 4372

My knowledge doesn't go any deeper than that but thought I'd share what I know.
