It is available in Emacs-26, however (require 'subr-x) should be added.

There is `org-trim' and despite it is less generic, likely it can be 
used if subr-x is avoided for some reason.

The manual does even mention the "html-postamble" option. Just the
variable. I am confused. Was it removed at some point? (I do not see any

I am attaching a tentative patch to fix this.
However, I am not sure if I replaced \\ with \\\relax in the right
places.

Re: The Org mode in the Org Git does not export

Ihor Radchenko  writes:

Performance back to normal!  Though, I noticed two issues.

*** ISSUE 1: Error when exporting. ***

While exporting, I see the error:

"Org mode fontification error in # at 10"

The error does not bother me, but I mention it in the case it relates to
the next issue.

*** ISSUE 2: Problems re-opening the notebook. ***

Reproduction steps:

1. open 'notebook.org' (C-x C-f ~/notebook.org RET)
2. export to HTML and open (C-c C-e h o)
3. kill the notebook buffer (C-x k RET)
4. re-open notebook (C-x C-f ~/notebook.org RET)

Expected:

'notebook.org' opens

Actual:

*Org HTML Export LaTeX* opens, with the following content:

\begin{align*}
  \frac{dy}{dx}
  & = y \left( -1 - 2 \tan x - \frac{2x + 1}{x^2 + x + 1} \right)
  \\
  & = \frac{e^{-x} {\cos}^2 x}{x^2 + x + 1}
\left( -1 - 2 \tan x - \frac{2x + 1}{x^2 + x + 1} \right)
\end{align*}

P.S. The original file remains intact, but given the way we implement
exports in Org, I think we should add two tests to the test suite to
verify that:

(1) re-opening the file after export always re-opens it, and
(2) no corruption happens to the original file after export.

I do not see how it is related.
Do you see the error with your config or with clean Emacs?

Oops. Another side-effect of `buffer-file-name'. Fixed now.

Done.

I am not sure how to test this part.
I instead documented the caveats in `org-export-copy-buffer' docstring
and in the `org-html-format-latex'.
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=17708ab3fa4f2a0f118bf86cebd4753f50e8bb26

Though maybe the code in `org-html-format-latex' should be factored out
into a separate macro like `org-export-with-persistent-buffer-copy'. The
macro will accept buffer name as an argument and do everything necessary
to not keep the `buffer-file-name' around.

I was just asking, out of curiosity, if it was planned to be published.
I really don't know where it could be published. I know PeerTube exists,
but I don't know how it works.

There is the YouTube option, which I imagine no one would like (me
neither). The only thing in its favor is that Invidious can be used to
watch the videos. BTW, I watch YT videos through Invidious in Emacs,
with the Ytel package and EMMS/MPV.

Ihor, thank you for looking into this issue. I have not read your patch 
with enough attention to check that regular paragraphs, list entries and 
other elements are handled as well. Just a couple of notes:



+(defconst org-latex-linebreak-safe "\\relax"


Is there a reason why you did not add \n at the end? It could help to 
avoid a lot of `concat' calls.



-   (equal "\\begin{tabular}{l}\n\\(x\\)\n\\end{tabular}"
+   (equal "\\begin{tabular}{l}\n\\(x\\)\\relax\n\\end{tabular}"


May be left as is since the line next to \\ does not start from square 
brackets.

If I understand, "a" should be less than "B" when under "C" locale when

When case is not ignored (4th argument is nil) locale-dependent 
collation rules are used, so you get the expected result.


$ printf 'a\nB\n' | LC_COLLATE=C sort

a
$ printf 'a\nB\n' | LC_COLLATE=en_US.UTF-8 sort

[FYI: If I replace nil with t, the procedure returns nil too.]

Tested on Emacs 29 (adaa2fc90e) and Org 9.5.5 (580f28614).


Strange. Emacs-26, Linux

(string-collate-lessp "a" "B" "C" t)
t

If libc is sane (assuming that sort is linked to the same libc)

printf 'a\nb\n' | LC_COLLATE=C sort
printf 'b\na\n' | LC_COLLATE=C sort
printf 'A\nB\n' | LC_COLLATE=C sort

printf 'B\nA\n' | LC_COLLATE=C.UTF-8 sort

then you might face an Emacs bug.

One thing I always mention when conversations about recording come up is
that if you promote recordings as a resource, it is considered good form to

world be under no ADA obligations (unlike company meetings) but still good

Update Org to MathJax 3

[Rudolf Adamkovič]

Hello smart people!

With all the talk about Emacs 29, I figured we should update Org Mode to
use MathJax 3, to catch up with the rest of the world.

>From the documentation (for MathJax 3.0 released in 2019):

> Version 3.0 of MathJax is a complete rewrite of MathJax from the
> ground up, and its usage and configuration is significantly different
> from that of MathJax version 2.

In practice, MathJax 3.2 renders mathematics faster and better, plus it
significantly improves LaTeX support.  For instance, one can typeset
calculus with the built-in (!) 'physics' package, like in LaTeX.

More information on the recent progress (made in 2019-2021):

https://docs.mathjax.org/en/latest/upgrading/whats-new-3.0.html
https://docs.mathjax.org/en/latest/upgrading/whats-new-3.1.html
https://docs.mathjax.org/en/latest/upgrading/whats-new-3.2.html

See the attached [working, but WIP] patch.

My question for you:

How do we change the 'org-html-mathjax-options'?

- 'scale' has now the value in [0, 1] and not in [0, 100]
- 'scale' should exist as a number and not string
- 'font' did not make it to MathJax 3 [*]
- 'linebreaks' did not make it to MathJax 3 [*]
- 'autonumber' has the values in lowercase now
- 'autonumber' became 'tags' in MathJax terminology

[*] coming in MathJax 4, currently in alpha

How does Org mode approach these kind of breaking changes?

Rudy
