Footnote-like custom function for org-roam-insert

Question

I am trying to make a custom function for org-roam which inserts footnote-like links in the current note.

The idea is to insert links on this way

The logistic regression [fn:20200612000001]...

* Footnotes

[fn:20200612000001] [[file:20200612000001-definition_logistic_regression.org][Logistic regression]]

and the linked file has the form

:PROPERTIES:
:ID: 20200612000001
:END:
#+TITLE: Definition Logistic Regression

I just copy-pasted the original org-roam-insert function and hacked it a little to insert the footnote. The code is here https://gist.github.com/maikol-solis/ed149c16cff16a55492d1acba8c12025.

However, after a couple of times using it, emacs crashes completely. I think that is caused by this function because this has never happened before.

I used gdb to follow the crash and this is the output:

Thread 1 "emacs-gtk" received signal SIGSEGV, Segmentation fault.

I appreciate any help to solve this issue. Best.

Answer 1

I updated the code and everything is working now. Around this line https://gist.github.com/maikol-solis/ed149c16cff16a55492d1acba8c12025#file-org-roam-insert-footnote-L47

I added this

(find-file target-file-path)
(setq target-vector-id
      (car (org-roam--extract-ids target-file-path)))
(kill-current-buffer)

I still don't know why occurred the crash, but it works.
