Elisp in org-mode for counting tag groups by edumerco in c/emacs@lemmy.ml

[-] edumerco@lemmy.ml 0 points 11 months ago

Dear @sachac (BTW, are you the legendary Sacha Chua?)

There was a parenthesis missing in the end, but it is working!!! :)))

I still have to understand the scope (does it works on the heading/ tree where it is called only, can I "point it" to a specific table, etc.) but it is a really great step forward.

And, as I wanted, it is short, simple, elegant, works perfectly and -specially- shows the power of elisp and how literate programming can be useful and powerful for reproducible research (this is part of my thesis).

I may continue with some questions, but it helps me a lot to learn.

Thank you so much! :D

Dear all. I get that it may be a tad complicated, but if anyone sees at least a reference about how it may be done, please do share it here. Thanks a lot, in advance... :)

Elisp in org-mode for counting tag groups (lemmy.ml)

Dear emacs and org-mode comrades.

Given:

a table with
- a list of tags +
- their number of appearances in question 1 (Q1) & and question 2 (Q2).
org support for tag groups (https://orgmode.org/manual/Tag-Hierarchy.html)
3 defined tag groups
- GroupTag1 (GT1)=tagA+tagC+tagD and
- GroupTag2 (GT2)=tagB+tagE
- GroupTag3 (GT3)=tagB+tagC+tagD (yes, some tags are in more than 1 group)

How can I count with pure elisp (assuming some table formula but I'm open to other ways) the sum of individual tag appearances of each tag group, for each question?

Example:

| tag  | Q1 | Q2 |
|------+----+----|
| tagA |  9 |    |
| tagB |  4 |  2 |
| tagC |  1 |  4 |
| tagD |    |  5 |
| tagE |    |  6 |
|------+----+----|
| GT1  | 10 |  9 |
| GT2  |  4 |  9 |
| GT3  |  5 | 11 |

Thanks a lot for your time and attention... :)

How to make undo work in the scratch buffer by edumerco in c/emacs@lemmy.ml

[-] edumerco@lemmy.ml 1 points 3 years ago

Maybe you can try to fix your issue by forcing the buffer-undo-list variable to nil for the elisp mode, as follow: (add-hook 'elisp-mode (lambda () (setq-local buffer-undo-list nil)))

I tried it but still no joy...

Looking at this issue I noticed 3 things that may help to pinpoint the origin...:

I have 2 variables set that affect the scratch buffer in my config (without yours, that it's the 3rd):

                  (setq initial-major-mode 'org-mode)
                  (setq-default major-mode 'org-mode)

Before this reply, (setq-default major-mode 'org-mode) was (setq default-major-mode 'org-mode). Both expressions seems indistinguishable in the resulted behavior.
The scratch buffer starts in org-roam mode (and read-only mode), which is very strange, but can obviously be related and/or part of the problem. The org-roam section (my config is literate in org-mode) comes before this variables being set.

What does this info may imply?

Hi @ouigol@beehaw.org.

I'm using vanilla emacs with my own configuration. And replying to Sunoc made me remember that the scratch buffer starts as read-only and not in org-mode. So it seems it comes from there... I'll have to bissect it?

Thanks a lot... :)

Hello Sunoc.

the buffer is not in read-only, but it always start as so.
the keybinding is ok since it works in all the rest of the buffers.
Upon calling undo, emacs says "no undo information in this buffer" (searching for this didn't seem to give relevant information except something from 2006 and then something about specific of a table-spreadsheet that I don't use).

From this and @ouigol@beehaw.org (I will relpy after this one) it looks that it may be my configuration, since I'm using vanilla emacs with my own configuration.

Anyway, thanks a lot for your time! :)

Dear fellow emacsers.

How can we make undo work on the scratch buffer? I'm sure it is a simple configuration issue, but I'm not getting the appropriate keyword to find the relevant documentation.

Thanks a lot in advance for your help and attention...
