Would we like to add a feature like that to Emacs?
I don't know how much work it would be, but I think
it would be a desirable change if it is easy.

Re: feature request: easy embedding of images

[Jude DaShiell]

To help accessibility it would be useful when an image was dragged into
org-mode if the user got prompted for an image description that gets
associated with the image in org-mode.  Some images are art work and those
should get alt="" tags if a user fails to provide a description but only
after asking if this image is art work or something that needs a
description.  If a description is provided that should go between the
quotes in the alt="" tag.

Russell mentioned a package and pointed to the image issues related to
Emacs, not Org.

I want to suggest the package https://github.com/abo-abo/org-download
which I use all time, for dragging and dropping images and for taking

Have you looked at org-attach-screenshot?

https://github.com/dfeich/org-screenshot

It uses org-attach and calls out to take a screenshot.

I do the same with some local function's I wrote a while ago. It works
very well for me. I run M-x my/org-screenshot, and after 3 seconds it
will use Imagemagick's "import" command to allow me to select a region
to screenshot and saves it to a filename I prepared.

I do this daily, many times each day.

This is Emacs, not Org. Perhaps someone knows how to adjust that.

Mine jumps too, but again that's Emacs, not Org.

I can't answer that. Drag and drop functions depend on your
platform. Does anything else in Emacs use drag and drop?

I do save all of mine to the same directory as my org file in
.org/Filename.org.screenshotMMDDHHMMSS.png. It means I can easily
know what files below to my org document.

Of course it's valuable, and already implemented. I think you're

Re: RFC on implementation adding buttons beside headings

FWIW, instead of inserting some blank spaces, you could overlay existing
characters, you'll just need to re-inject them at display time so that
the display doesn't change. That way, you don't modified the text.


Here is a way to add a button, in place, without modifying the
buffer.  The trick is to overlay the EOL and to re-inject an EOL
using the "after-string" property.


 (with-current-buffer (generate-new-buffer "=test")
   (cl-flet ((run (f) (lambda ( args) (interactive) (funcall f
 (let (pos)
   (insert "* My title\n")
   (setq pos (1- (point)))
   (insert "An amazing note.\n\n")
   (insert "** My 2 title\n")
   (insert "An even more amazing note.\n")
   (org-mode)
   (make-button pos (1+ pos)
'before-string "\n\n"
'display '((height 2) "Click me!")
'after-string "\n\n"
'face 'custom-button
'action (run (lambda () (message "Thanks!")))
)))
   (pop-to-buffer (current-buffer))
   )
   
Note that the above expression requires lexical-binding.

org-latex foreground color in svg is controlled by org-latex-and-related

[Wei-Ting Lin]

Recently I found the foreground color of the latex-preview in org-mode is
controlled by "org-latex-and-related".

There is another option called "org-format-latex-options", which can also
set the foreground color, but it has no effect for the svg output.

I don't know if this behavior is by design or a bug, but I hope we can have
an option to have different colors for them.

feature request: easy embedding of images

[Alexis Gallagher]

Hello, my fellow org-mode lovers,

This is a feature request — or failing that, a request for advice on a settings 
configuration which could produce this functionality now. 

I wish org-mode had the ability to attach images to notes, display them inline, 
and have that work well. By “work well” I mean a few specific things:

•   the image is automatically resized to maintain aspect ratio and 
fit horizontally with a civilized margin, so that I can resize my emacs window 
without the image disappearing or swamping the other content. 
•   you can still scroll the window one line height unit at a time, 
without the entire image being scrolled as if it were one giant line, breaking 
scrolling, as seems to happen on my emacs (version 28.x on Linux)
•   drag and drop, so I can add the image by dragging it in, for 
instance from a screenshot tool or from an image on a web page.
•   sensible defaults for storing the images bundled with notes and 
keeping the two associated, so that I don't subsequently live in fear of ever 
moving my org files

Why is this valuable, to me at least? I use org to take notes all day, during 
meetings, on reading matter, in the development of my own thoughts. Embedding 
images would let me collect every kind of resource I can't reproduce by typing 
or copy and pasting text — photos of slides during presentations, photos of 
whiteboard,  key snippets from websites, handwritten notes and equations, etc..

Humm. Emacs is amazing: it managed to guess the right encoding, from the
buffer context, probably...

But, what you are giving to 'org-export-string-as' is not the buffer,
it's a string. So, let's try the same without using an org function:

 (with-temp-buffer
   (insert (with-temp-buffer
 (insert-file-contents-literally "~/unicode.org")
 (buffer-string)))
   (secure-hash 'md5 (current-buffer)))
   
And, that fails, requesting an encoding.


> In the context of Org export, secure-hash seems to require a coding
> system.  Why?

I'm not an expert, so, you'll need to confirm with other sources.  But
secure-hash requires an encoding in all cases, to compute the hash of
some text, because it needs the array of bytes that represents that text
to compute its hash.

I don't see any bug in org, and, I don't see any bug in secure-hash either.

You literally shoud stop using "literally" ;-)

And, you might want to read:

Re: Links to external targets with (or despite) org-ref

[John Kitchin]

The quickest thing might be to remove the store properties on the ref
links. This should do it.

#+BEGIN_SRC emacs-lisp
(cl-loop for reflink in '("ref" "pageref" "nameref" "eqref" "autoref"
"cref" "Cref" "crefrange" "Crefrange")
do
(setf (cdr (assoc reflink org-link-parameters))
  (org-plist-delete (cdr (assoc reflink org-link-parameters)) :store)))
#+END_SRC

I guess I don't have that setup quite right in org-ref, it seems like it
should not clobber other ways to store links.

Hi All,

Following some feedback I’ve received from a few people (including off-list),
here’s a v2 set of patches.

Notably, I’ve now got a draft manual entry (see the last patch attached), which
should go a long way to better explaining what this is without asking you to
wade through all the code comments :)

All the best,

Great point. I had originally used advice to avoid a loop.  However, when it

[O] Injecting properties with noweb

[Ken Mankoff]

Hello,

Is it possible to set variables using Org Babel inside screen, which does not 
support ":var" header args? I'd actually lke a double-nested screen over ssh, 
and the ability to re-use Babel code blocks under different headings, using 
header args or PROPERTIES to change variables. That is, something like:

* Setup
:SETTINGS:
:FOO: default
:BAR: one
:header-args:screen+: :cmd /bin/bash :session (org-macro--get-property "FOO" "")
:END:

#+NAME: setup
#+BEGIN_SRC screen
if [[ ! $(hostname) =~ "host"* ]]; then ssh host; fi
<>
# eval <> ??
echo $FOO
#+END_SRC

Should print out "one" (the default setting under Setup) in the screen terminal.

** OTHER
:PROPERTIES:
:FOO: two
:END:

#+BEGIN_SRC screen
<>
#+END_SRC

Should print out "two" (the sub-heding adjusted property) in the screen 
terminal.


I'm OK with not being able to inject arbitrary variables, only the ~10 or so 
that I need to be able to set, and having a code block that has these 10 
hard-coded on the LHS, but with some <> or something on the RHS so that 
they value of the variable can be controlled using PROPERTIES under headings 
(better yet, header-args, but I don't think that is possible).  

That's the behavior I'm after, but am having trouble. I thought something like:

#+NAME: get-prop
#+BEGIN_SRC emacs-lisp :var prop="FOO" :noweb yes
(org-macro--get-property prop "")
#+END_SRC

#+NAME: inject_vars
#+BEGIN_SRC shell :noweb yes
# echo <> # testing
echo export FOO=<>
echo export BAR=<>
echo export BAZ=<>
#+END_SRC

#+BEGIN_SRC screen
<>
echo $FOO
#+END_SRC

might work, but it's just printing nil.


Thanks for any suggestions,

  -k.

Help needed with subtree export

[Alain . Cochard]

I only recently discovered subtree export, which I thought would be
better suited for me, but I have trouble to switch.

Consider the following file:

   #+SELECT_TAGS: export conditional
   #+EXCLUDE_TAGS: 

   #+OPTIONS: toc:nil title:nil author:nil date:nil tags:nil

   * I  :export:
   ** 1
   ** 2
   ** nth
   *** conditional :conditional:
   * II

If I use 'C-c C-e l o', I have everything under '* I' exported. If I
transfer 'conditional' from '#+SELECT_TAGS:' to '#+EXCLUDE_TAGS:', I
have everything under '* I' except the '*** conditional' headline.
This is want I want: be able to selectively include/exclude the
headlines with the ':conditional:' tag by simply transferring
'conditional'.

Now, if I use 'C-c C-e C-s l o' on '* I', it gives the same as above
when 'conditional' belongs to '#+EXCLUDE_TAGS:' but, after the
transfer of 'conditional' to '#+SELECT_TAGS:', only the '** nth'
headline is exported.

Is there a convenient way to achieve my goal?  Sure, I can put an
':export:' tag on '** 1', '** 2', and '** nth', but it is not very
practical.  I can also introduce a 'fake' headline and subtree export
it instead:

   * fake
   ** I :export:
   *** 1
   *** 2
   *** nth
    conditional :conditional:
   * II

but I don't like this workaround either.

Thanks in advance


PS: I have a minor comment about the manual: when reading the following

   ‘SELECT_TAGS’
The default value is ‘("export")’.  [...]

   ‘EXCLUDE_TAGS’
The default value is ‘("noexport")’.  [...]

I find it difficult to anticipate what will happen when there is no
tag at all.

It is not clear to me why it would be a problem to use 'backend' in
code symbols as well, but the only important thing for me as a user is
that the terminology be consistent throughout the documentation.  So
yes, it makes sense.

The link you provide is very convincing.  Will it still hold in 5 or
10 year from now?  (see end of

+ is a bit awkward.
Space would be more logical as separator.
Though I am wondering if people are using noweb reference names with
spaces in the wild.

I do not like the idea of using tags.

What we might do is:

1. Leave :noweb-ref's current behavior of overwriting the parent
   parameter values.
2. Add a new :noweb-ref+ parameter to accumulate multiple noweb
   reference names. The relevant function to modify is
   `org-babel-merge-params'

Why not simply doing the `should' test when the
`test-ob-shell/uuid-regex' match fails? Instead of returning `t'. Then,
we will not need to use advise.

What about recording the type of timestamp range in the parser?
Then, interpreter can simply examine the range type and emit the correct
timestamp string.

Makes sense.

So, given that the parsing is extended cleanly, I do not think that
maintenance burden will increase all that much. It may even benefit from
someone taking a fresh look and possibly refactoring org-table TBLFM
parser.

IMHO, it is not sufficiently integrated with org-table.el facilities in
its current state. I'm afraid that we will have code duplication if
include orgtbl-fit as is.

BTW, the dollar replacement is something org-table can benefit from---a
number of people are confused because "$" is treated specially by Calc.

We can, but it should be first and foremost added to GNU Calc. On Org
side, we just need appropriate integration. Maintaining generic data
analysis code in Org is out of Org's scope.

Contributing to GNU Calc will also benefit GNU Calc users who don't use
Org mode.

Yes, that works.

However, if I use insert-file-contents-literally with a unicode
file, I do *not* have to set the coding-system-for-write.  This just
works:

   (with-temp-buffer
  (insert-file-contents-literally "~/unicode.org")
  (secure-hash 'md5 (current-buffer)))

In the context of Org export, secure-hash seems to require a coding
system.  Why?

I looked further, and the situation is not as simple.
https://grammarhow.com/backend-back-end-or-back-end/, for example,
claims that only "back-end" is grammatically correct.

I am now thinking to do the following:
1. Use "backend" in the code symbols
2. Use "back-end" in docstrings and the manual.

Would it make sense?

If you're always using utf-8, here is a way to force it so that
secure-hash can compute the hash. This should work:

   (with-temp-buffer
  (let ((coding-system-for-write 'utf-8))
(insert "Lechtenb\303\266rger")
(secure-hash 'md5 (current-buffer

Without setting coding-system-for-write to utf-8, it asks for an
encoding:

   (with-temp-buffer
  (insert "Lechtenb\303\266rger")
  (secure-hash 'md5 (current-buffer)))


I'm still no getting your use case, but, let's hope that this naive hack
is enough for you :-)

I can call secure-hash on the buffer with literally inserted

Thank you for the clarifications.  Probably I have to do that.

For the record, if I insert "Lechtenb\303\266rger" as string into a
buffer, secure-hash asks for a decoding.  If I insert that literally
via an UTF-8 encoded file, secure-hash works.

I want to be sure to use the file contents in unchanged form, as
promised by insert-file-contents-literally.  For now, I copied part
of the code from insert-file-contents-literally to avoid
after-insert processing and file handlers.  I still do not

Not quite sure what "depression" means in your message -- my guess is
the act of "releasing" this key.  Either case, I cannot reproduce your

What is your keyboard configuration?  I'm using a US keyboard and I
suspect you are observing something from key composition.  Or maybe from
your Emacs input method like latex.  Attaching the result of this might

In an org-mode buffer, I notice a depression of the minus-key `-' now
also gives an under-bar. I find this very annoying. I never insert the
subsequent letter `—' whatever it's called, and I do not want it. How do
I remove this "feature" such that a depression of the minus-key will
