[PATCH] Add yank-media handler for LibreOffice Calc tables

[Visuwesh]

[-- Attachment #1: Type: text/plain, Size: 199 bytes --]

Attached patch adds support for yanking LibreOffice Calc tables as Org
tables.  Tables from docx files (or LO's equivalent) cannot be yanked
though since the mimetype for them are richtext or HTML.

Thanks!

I just tried your patch (make repro) with a simple table

foo	bar	
1	2	3

I got

* This is test
| f\0o\0o\0 | \0b\0a\0r\0 | \0    |
| \01\0     | \02\0       | \03\0 |
| \0        |             |       |

Something is off with encoding.

What if the point is in the middle of something else?
For example, in the middle of another table.
Then, conversion may yield wild outcomes.
Maybe it is safer to convert region in a temporary buffer and
insert the final result into the Org document being edited.

I cannot reproduce it on my end.  I tried with different documents and
document types (Excel and LO format).  Would it be possible to send the
faulty file?

Even if we do the processing in a temporary buffer, we would still end
up inserting the table after point.  I say we leave it to the user to be
prudent and not call yank-media when in the middle of a table or
somesuch.  We do not do any special handling in other handlers, so why
do it here?

Here is the recipe
1. make repro (I tried with the latest Emacs master and with Emacs 29)
2. Open test.odt (attached)
3. M-x org-mode
4. Copy the non-empty cell area
5. M-x yank-media <RET> app<TAB> <RET>
6. Observe encoding problems

Consider the following example:

* Heading <point>

M-x yank-media ... will slurp the heading

| * Heading a | b | c |

In contrast, the existing handlers will only insert some text at point,
never touching the text around.

Thanks for the reproducer.  I think this might be locale-dependent.  I
fail to reproduce on my end with the following locale settings:

    LANG=en_GB.UTF-8
    LC_COLLAGE=ta_IN.UTF-8
    LC_MONETARY=ta_IN.UTF-8
    LC_NUMERIC=ta_IN.UTF-8

    locale-coding-system = 'utf-8-unix

I have no idea how to deal with locale issues like this unfortunately.

Would it be sufficient to unconditionally insert a newline after point?
Maybe even after going to end of current element (if that can be done).

It will be more fragile compared to using temporary buffer.
As an alternative, you can apply narrowing around the call to
`org-table-convert-region'.

Also, do note that any text exceeding
`org-table-convert-region-max-lines' will lead to
`org-table-convert-region' throwing an error.

Thanks for the explanation.  I understand your initial suggestion.  I
will use a temp buffer in an updated patch.

Catching that and messaging the user should be sufficient?

I will post an updated patch if someone comments on how to resolve the
encoding issue.

I tested a bit further, and it might not be locale. Maybe it is some
LibreOffice version issue or build issue.

Below is the DATA passed to yank handler:

Debugger entered--entering a function:
* org--libreoffice-table-handler(application/x-libreoffice-tsvc #("1\0\11\0002\0\11\0003\0\n\0004\0\11\0005\0\11\0005\0\n\0" 0 24 (foreign-selection application/x-libreoffice-tsvc)))
  yank-media()

As you can see, the data contains \0 characters.

Maybe. Or we may catch and ask user to lift the restriction temporarily.
Something like:

Inserting large table with more than `org-table-convert-region-max-lines' <number>. Continue? (yes/no)

My LibreOffice version is

    % libreoffice --version
    LibreOffice 24.2.5.2 420(Build:2)

Just to be sure that yank-media is not in the middle of encoding
problem, can you say what

    (gui-get-selection 'PRIMARY 'application/x-libreoffice-tsvc)

returns?  If it contains NULL bytes too, then I would be completely
clueless.

Ah, something like what Calc does.  Yes, I will go with this approach.

It might not be the version after all...  I downloaded the AppImage from
https://appimages.libreitalia.org/ (listed in
https://www.libreoffice.org/download/appimage/) and it does not have
NULL bytes at all:

    Debugger entered: (#("1\0112\0113\n4\0115\0116\n" 0 12 (foreign-selection application/x-libreoffice-tsvc)))
      (progn (debug nil (gui-get-selection 'PRIMARY 'application/x-libreoffice-tsvc)))


\011 is the TAB character.

    % ./LibreOffice-7.4.6.2.basic-x86_64.AppImage --version
    LibreOffice 7.4.6.2 5b1f5509c2decdade7fda905e3e1429a67acd63d

Thanks so it is confirmed that yank-media does not do any conversion.
What if you instead do

    (x-get-selection-internal 'PRIMARY 'application/x-libreoffice-tsvc)

?  I am not sure if it will reveal anything.  Also, what is the value of
x-select-request-type?

Sorry, I am seriously out of clues.  We could outright remove the NULL
bytes if they do not change the underlying text but this feels like a
hack...  I hope someone else can reproduce this issue on their end.  I
do not have another Linux system in which I could freely install Emacs
and test this out.

I'm not familiar with yank-media in any way, but here are the results of the
commands you sent in this thread. They're all tested on the test.ods sent by
Ihor.

    $ libreoffice --version
    LibreOffice 24.2.6.2 420(Build:2)

    (version)
    "GNU Emacs 29.4 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.43, cairo version 1.18.2)"

    (gui-get-selection 'PRIMARY 'application/x-libreoffice-tsvc)

nil. However,

    (gui-get-selection 'CLIPBOARD 'application/x-libreoffice-tsvc)

#("foo	bar	
1	2	3
" 0 15 (foreign-selection application/x-libreoffice-tsvc))

> What if you instead do
>
>   (x-get-selection-internal 'PRIMARY 'application/x-libreoffice-tsvc)

    (x-get-selection-internal 'PRIMARY 'application/x-libreoffice-tsvc)

nil. However,

    (x-get-selection-internal 'CLIPBOARD 'application/x-libreoffice-tsvc)

#("foo	bar	
1	2	3
" 0 15 (foreign-selection STRING))

Also:

    Debugger entered--entering a function:
    * org--libreoffice-table-handler(application/x-libreoffice-tsvc #("foo\11bar\11\n1\0112\0113\n" 0 15 (foreign-selection STRING)))
      yank-media()

> Also, what is the value of x-select-request-type?

nil.

`current-locale-environment' is "en_US.UTF-8"

I hope that this is helpful.

Thank you, this helps a lot!  The fact that you had to change PRIMARY to
CLIPBOARD should not be a problem in practise: (1) LO should be putting
the data in the CLIPBOARD anyway, and (2) yank-media abstracts this away
for us.

If possible, could you please try LibreOffice 7.6.4? The version Ihor
has installed in his system.  There is an AppImage available for you to
try.

Yep, on 7.6.4 the problem occurs.

    $ ./LibreOffice-7.6.4.1.basic-x86_64.AppImage --version
    LibreOffice 7.6.4.1 e19e193f88cd6c0525a17fb7a176ed8e6a3e2aa1

    Debugger entered--entering a function:
    * org--libreoffice-table-handler(application/x-libreoffice-tsvc #("f\0o\0o\0\11\0b\0a\0r\0\11\0\n\0001\0\11\0002\0\11\0003\0\n\0" 0 30 (foreign-selection STRING)))
      yank-media()

, resulting in

    | f\0o\0o\0 | \0b\0a\0r\0 | \0    |
    | \01\0     | \02\0       | \03\0 |
    | \0        |             |       |

To narrow it down a bit more: the problem exists in 7.6.5.2, and does not exist in the
following release, 7.6.6.3.

Thank you!  So it is most likely not locale related---a major headache
saved.  I will look into this soon (cannot promise anything this week
unfortunately).
