A question about org-super-links-backlink-prefix customization

[vincent-picaud]

I have two files

• file_A.org

file_A.org
* Introduction

• file_B.org

file_B.org
* Introduction

what I would like when I create links is

• file_A.org

* Introduction
:PROPERTIES:
:ID:       045bb041-3130-4ef8-bf50-f9ad0b284180
:END:
A link: [[id:a54fca82-c47a-4529-aa51-bb14403801a0][Introduction]]

• file_B.org

* Introduction
:PROPERTIES:
:ID:       a54fca82-c47a-4529-aa51-bb14403801a0
:END:
:BACKLINKS:
*<<-* file_A::[[id:045bb041-3130-4ef8-bf50-f9ad0b284180][Introduction]]
:END:

I have modified org-super-links-backlink-prefix as follows:

 (setq org-super-links-backlink-prefix
     #'(lambda () (concat "*<<-* " (file-name-nondirectory (file-name-sans-extension (buffer-file-name))) "::"))))

but with that what I get is

• file_B.org

* Introduction
:PROPERTIES:
:ID:       a54fca82-c47a-4529-aa51-bb14403801a0
:END:
:BACKLINKS:
*<<-* file_B::[[id:045bb041-3130-4ef8-bf50-f9ad0b284180][Introduction]]
:END:

You see that "file_B" is used instead of "file_A". The reason is that (buffer-file-name) is evaluated in file_B.org when the back link drawer is created. What I would like is the function that returns me the buffer-file-name of file_A.org instead.
Maybe this function is already avalaible in org-super-links.el. Do you have an idea to help me ?

Thank you for this package ! :)

Hey, interesting, you are right on the reason why it functions that way. I'll try to take a look at the code soon and see if there is a good way to handle that use case. It's been a bit since I've looked closely at it.

So unfortunately it looks like there is not really a straightforward way to do what you want. You could duplicate the org-super-links--insert-link and org-super-links-insert-backlink functions. Change org-super-links--insert-link to pass in the marker to the source as an extra param in the call to org-super-links-insert-backlink and then jump to the marker there to get the buffer name. You could do something similar by modifying org-super-links-links-action. Both feel pretty gross though.

If I think of something better I'll let you know.

Thank you for spending time to think about my problem.

I understand, and this is a valuable feedback.

Do you want me to close this question or to keep it active ?
