Hmm - mine gave a different result: I cloned the org-mode archive from
https://git.savannah.gnu.org/git/emacs/org-mode.git, called "make" and
ran the tests as described in the "testing/README".  That gave 6 failing
tests.

Then I blindly replaced every occurrence of `condition-case' with
`condition-case-unless-debug' (everywhere but not in the tests), ran
"git clean -xf", then "make" again, and ran the tests again.  Again 6
failing tests.

Not sure if I did something wrong.

Formulas on table cells containing '$'

[Jeff Trull]

While investigating an error executing a table formula I discovered that
cells containing '$' cause column references to be executed even when no
attempt is made to evaluate cell contents as code. Here's a simple example:

#+TITLE: demonstrate strange error in currency column

| 3/1/2023  | Deposit| $200.00 |
| 3/13/2023 | Interest   | $1.13   |
| 4/1/2023  | Deposit| $301.22 |
|---++-|
|   | Number of Transactions | |
#+TBLFM: @4$3='(length '(@1$3..@I$3))

Evaluating the table formula produces a 'Invalid field specifier "$200"'
message. In more complicated examples you just see a #ERROR in the cell.
With formula debugging turned on, I can evaluate the expanded expression
with no errors.

This is surprising for a number of reasons:

   1. The formula makes no use of the cell contents
   2. The formula debugger notes an error but actually shows a valid
   expression
   3. Columns with currencies will be fairly common esp in imports from
   financial institutions
   4. This error happens before the formula is evaluated so there is no
   chance to remove the problem character in the formula as I do with the
   commas ',' which are also present

Is this by design? If so, I was unable to find any documentation explaining
it.

Thanks,
Jeff

 Of course, 26 should be a defcustom rather than a hard-coded constant.

[BUG] Some Org mode files require org-macs.el more than once

[Niall Dooley]

Reviewing some Org files I noted the following files require org-macs.el more
than once:

- ob.el
- ob-python.el
- org-fold.el

There are likely others too.

The additional require seems redundant to my ignorant self.  I appreciate this
should cause no issue but is there a reason why such lines are duplicated?
I've indicated this as a BUG in the subject line so forgive me if that is an
inaccurate characterisation.

Here is the source code of `org-toggle-inline-images'. I implement this

Well. What ob-java does is mostly for historical reasons and because
some users of Java source blocks tend to use a lot of local classes
defined in current directory. See
https://list.orgmode.org/orgmode/87imadafo0@iki.fi/
ob-java does not really aim to generate compiled source in :dir for
the sole purpose of generating the compiled source.

I feel slightly reluctant about adding side effects to babel evaluation.
Not too reluctant though.

I'd like to hear from other ob-C users, so I changed this thread into a poll.

We probably have a misunderstanding about the role of
`org-use-fast-tag-selection'.

`org-use-fast-tag-selection' _currently_ determines whether to display
the tag selection window at all:

Non-nil means use fast tag selection scheme.

This is a special interface to select and deselect tags with single keys.
When nil, fast selection is never used.
When the symbol auto, fast selection is used if and only if selection
characters for tags have been configured, either through the variable
org-tag-alist or through a #+TAGS line in the buffer.
When t, fast selection is always used and selection keys are assigned
automatically if necessary.

Even when the value is t, not 'auto, the user bindings for tags are
honored. `org-fast-tag-selection' never checks the value of
`org-use-fast-tag-selection'.

I think we should consider the option `org-use-fast-tag-selection'.
Because it controls the behavior that whether auto assign short-key to
tags. Make condition decision based on this option is needed. I hope you
can reconsider this.

ob-java.el deals with it by using a :dir header; if non-nil, the
compiled files are placed in that directory instead of
`org-babel-temporary-directory'. (And, by default, the :dir header is
"."). The filename is determined by the packagename.

org-element tutorial?

Hi,

Does anyone know of a good tutorial on using org-element? I'm finding
the documentation hard to grok.

Alternatively, given a doc like

   - item 2

* NEXT My thing

I want this

how would I get at the note entered for the state change, i.e. the "I
want this" list item, in this example  (which might be in a drawer,
just doesn't happen to be, here)?

Fair point.

I am not sure how I feel about such side effects of evaluation.
Is there any other babel backend that is doing something similar?

Ah. Thank you. That explains it.

I'd prefer something more closely resembling `org-latex-preview'
approach with prefix arguments:

Toggle preview of the LaTeX fragment at point.

If the cursor is on a LaTeX fragment, create the image and
overlay it over the source code, if there is none.  Remove it
otherwise.  If there is no fragment at point, display images for
all fragments in the current section.  With an active region,
display images for all fragments in the region.

With a C-u prefix argument ARG, clear images for all fragments
in the current section.

With a C-u C-u prefix argument ARG, display image for all
fragments in the buffer.

With a C-u C-u C-u prefix argument ARG, clear image for all
fragments in the buffer.

`org-toggle-inline-images' should also be changed.

I do not think that we need to care about the value of
`org-use-fast-tag-selection'.  Instead, just

1. If the total number of tags does not exceed
   `org-fast-tag-selection-maximum-tags', display them all.
2. If the total number of tags is larger, just display all the bound
   tags + any extra tags, up to `org-fast-tag-selection-maximum-tags',
   and add a note in the tag selection buffer that more tags are not
   displayed.

In my attempts, the tests started failing for no obvious reason.
Just from changing `condition-case' to `condition-case-unless-debug'.

Though I did not investigate if it happened for every atomic change.
