It is good that you have a solution, albeit with the caveat you mention above.

A couple of thoughts:

There is a hook that operates on the copy buffer before parsing viz. 
"org-export-before-parsing-functions is a variable defined in ‘ox.el’." (In 
older versions, it was org-export-before-parsing-hook.) Maybe you can add a 
hook that will add that prefix to all links, so you do not need to put it in 
your working files.

Or you could write an elisp macro that takes two arguments (link, desc) and 
uses them to either construct a link or your preferred substitute if it fails 
validation.

I am not sure if making a breaking change to public constant is the best

What about simply adding an extra entry:

Ideally it should not be a public constant. Values should be accessed
using a helper that returns "de" value for "de-de", "de-ch", "de-it"
without copies, unless a more specific key is defined as it is done for
de-at.


It is already a public constant. And I see no strong reason to change
this (strong enough to justify breaking change).


Every piece of code accessing this public constant must implement 
fallback from e.g. "de-ch" (or de_CH) to "de". Or to "en" for an 
unsupported language. To achieve consistent behavior it is better to 
provide a helper function.



I have a hope that properties may be generated from CLDR data, LaTeX
babel .ini files, etc. However it should be possible to override
specific properties.


For context, I plan to provide a global language-identifier alist that
will link human-readable language names to abbreviations like "de",
"de-de", etc.


This languange-region identifiers may be written in different way 
(dash/underscore, case), but they are used specify POSIX locale LANG, 
LC_* and extensions like LANGUAGE, so in some cases human friendly names 
may be less convenient.



Thus, auto-generating the alist may be not reliable. At least some
manual overseeing may be needed.


Of course, some overrides may be necessary. E.g. it was decided to use 
French inner quotes different from CLDR.



Though I am not sure if we can easily handle tricky
cases like weird installation directory for TeXLive or MikTeX.

fenrir-screenreader is installable with pip though you may need some

Why does this happen?

The gpg command given in the faq does not return what the faq claims will
be returned.
Look for the public key of Klaus Knopper:
bash: Look: command not found
bash-5.1$  gpg --keyserver pool.sks-keyservers.net --search-keys "Klaus
Knopper"
gpg: error searching keyserver: Server indicated a failure
gpg: keyserver search failed: Server indicated a failure
bash-5.1$

Thank you for the additional pointers!  I still need to check out
promising combinations of those approaches, also options for MBROLA
(which is not free, but applies a custom AGPL-3.0-but-not-be-sold
license to the voices).  ADRIANE is certainly fascinating.

Re: Suggestions for Text-To-Speech (TTS) from Org sources?

fenrir-screenreader is also available.
https://nashcentral.duckdns.org/projects/Jenux
uses fenrir by default.
Klaus Knopper's public key I haven't been able to find and none of his
email addresses seem to be working any longer either for the ones I found.
You have a chance of getting a good version of knoppix if you download
with a good bittorrent client and make sure your encryption required is
turned on and make sure of integrity checks.

Some Issues I Encountered While Developing Metanote

[note meta]

Dear org mode developers,

I'm the author of Metanote. A few days ago, I posted a thread on Reddit
with the title "Let's Talk About the Story of Metanote and Free Software."
https://www.reddit.com/r/emacs/comments/16db9gz/lets_talk_about_the_story_of_metanote_and_free/
You  can learn more about Metanote and me from there. In the replies to
that post, someone mentioned here, so here I am.

During the development of Metanote, I encountered some issues, as follows:
(Note that my testing environment is based on org mode 9.3.6, GNU Emacs
28.2. I haven't tested with the latest org mode, so I'm not sure if these
issues still exist.)

1. Dynamic Block Parsing Issue

   #+begin_example
#+begin
#+end:
   #+end_example

   The above is a Dynamic Block, and the parsed syntax tree is:

   (org-data nil (section (:begin 1 :end 17 :contents-begin 1 :contents-end
17 :post-blank 0 :post-affiliated 1 :parent #0) (dynamic-block (:begin 1
:end 17 :block-name nil :arguments nil :contents-begin nil :contents-end
nil :post-blank 0 :post-affiliated 1 :parent #1

   However, the following is not recognized as a Dynamic Block:

   #+begin_example
a
#+begin
#+end:
   #+end_example

   the parsed syntax tree is:

(org-data nil (section (:begin 1 :end 18 :contents-begin 1 :contents-end 18
:post-blank 0 :post-affiliated 1 :parent #0) (paragraph (:begin 1 :end 11
:contents-begin 1 :contents-end 11 :post-blank 0 :post-affiliated 1 :parent
#1)) (keyword (:key "END" :value "" :begin 11 :end 18 :post-blank 0
:post-affiliated 11 :parent #1

2. About Paragraph

   #+begin_example
+--+
+--+
+this is a paragraph+
+this is a paragraph+
   #+end_example

There should be only one paragraph above, but it's parsed as two:

(org-data nil (section (:begin 1 :end 55 :contents-begin 1 :contents-end 55
:post-blank 0 :post-affiliated 1 :parent #0) (paragraph (:begin 1 :end 6
:contents-begin 1 :contents-end 6 :post-blank 0 :post-affiliated 1 :parent
#1)) (paragraph (:begin 6 :end 55 :contents-begin 6 :contents-end 55
:post-blank 0 :post-affiliated 6 :parent #1

3. About Pre-blank

   The first blank line in a Greater Element is parsed as a paragraph.
However, this behavior is inconsistent in Items and Footnote definitions.
In Items and Footnote definitions, a blank line is parsed as a Pre-blank.
In Footnote definitions, especially, this blank line appears only once
because having more than one would break the Footnote definitions.

#+begin_example
[fn:a]

bbb
#+end_example

(org-data nil (section (:begin 1 :end 13 :contents-begin 1 :contents-end 13
:post-blank 0 :post-affiliated 1 :parent #0) (footnote-definition (:label
"a" :begin 1 :end 13 :contents-begin 9 :contents-end 13 :pre-blank 2
:post-blank 0 :post-affiliated 1 :parent #1) (paragraph (:begin 9 :end 13
:contents-begin 9 :contents-end 13 :post-blank 0 :post-affiliated 9 :parent
#2)


I'm a big fan of org mode. A few years ago, I couldn't find an app that
supported org mode on my phone, so I created one myself. I hope that
through my app, I can introduce org mode to more people, even those who are
not familiar with Emacs. I also hope to make some contributions to org mode.

Additionally, is it possible to include Metanote in the 'Tools that work
with Org' section at https://orgmode.org/tools.html ?  Metanote website is
https://metanote-dev.github.io/.

Best regards,
Zhen

Currently, the time is decided simply by my own availability.
If someone can host the meetup and be regularly available for
Asia-Pacific time zone, we can have a second timing. For example, by
alternating the meetup times (one in EU time zone, one in Asia-Pacific).
But someone needs to volunteer.

This sounds promising.  I’ll check it out.

Many thanks

Not really. The story starts from the previous discussion of
translations in your French quote patch:
https://list.orgmode.org/orgmode/87pm3e6qx3.fsf@localhost/

I started writing it and realized that the current situation with all
the translations scattered all over the place (at least, ox libraries,
column view, and org-clock) is not ideal. So, I plan to factor out all
the translations into a separate file (say, org-translate). That file
will also define common interfaces to work with language codes and
translating phrases.

That's very LaTeX-specific and will be limited to LaTeX export.
I do not see any problem since we have to support languages defined by
language code anyway, for backwards compatibility.

Should we move constants.el by Carsten Dominik to Org orphanage? (was: Erratum in "The Org Manual" 9.6)

The source code at https://github.com/cdominik/constants-for-Emacs has
not been changed since the end of 2020, and I have last seen Carsten
being active on mailing lists at the beginning of 2021.

So, we may instead consider marking the package at
https://orgmode.org/worg/org-orphanage.html and maybe inside
https://sr.ht/~bzg/org/ project.

It works on my side, when opening from inside org-manual.org, from Info
manual page, and from https://orgmode.org/manual/Cooperation.html. May
you please provide more details?

using mbrola is probably as good as possible with free software:
https://en.wikipedia.org/wiki/MBROLA

still not perfect, but much better than the builtin voices of espeak or
festival (YYMV).

Hi Ihor,

I would’ve liked to join, but that’s 1am (Malaysian time).

Apologies if I missed out on the thread for setting my availability.
