Open/Edit zettel gives only <nil> nil ()

[carlos-cardoso]

Hi, Thanks for all the work on this project.

I'm new to emacs and installed Doom (v2.0.9), emacs (28.0.50), and neuron with nix.

After creating some zettels with SPC z z, when I try to edit or open them SPC z e, or SPC z o, I get:

Edit zettel:
<nil> nil ()
<nil> nil ()
<nil> nil ()

After selecting one of the options nothing happens. With the elisp repl I found that the issue seems related to the neuron-zettel-cache

ELISP> neuron--zettel-cache
((c4bd7158
  (path . "/home/carlos/zettelkasten/c4bd7158.md")
  (day . "2020-05-19")
  (id . "c4bd7158")
  (title . "Index")
  (tags .
   []))
 (ef1be6a2
  (path . "/home/carlos/zettelkasten/ef1be6a2.md")
  (day . "2020-05-19")
  (id . "ef1be6a2")
  (title . "Writing")
  (tags .
   ["writing" "zettelkasten" "note-taking"]))
 (26a0709a
  (path . "/home/carlos/zettelkasten/26a0709a.md")
  (day . "2020-05-10")
  (id . "26a0709a")
  (title . "ZettelKasten")
  (tags .
   ["notetaking" "zettelkasten" "organization" "writing"])))

The neuron--propertize-zettel function seems to expect keys in the first element, by using cdr I got it to work (I know almost nothing about lisp).

(defun cdr-neuron--propertize-zettel (zettel)
  (neuron--propertize-zettel (cdr zettel)))

(defun neuron--select-zettel-from-list (zettels &optional prompt)
  "Select a zettel from a given list.
ZETTELS is a list of maps containing zettels (keys: id, title, tags, path)
PROMPT is the prompt passed to `ivy-read'."
  (let* ((selection
          (ivy-read (or prompt "Select Zettel: ")
                    (mapcar #'cdr-neuron--propertize-zettel zettels)
                    :caller 'neuron--select-zettel-from-list)))
    (get-text-property 0 'zettel selection)))

SPC z e now gives:

Edit zettel:
<c4bd7158> Index
<ef1be6a2> Writing (writting, zettelkasten, note-taking)
<26a0709a> ZettelKasten (notetaking, zettelkasten, organization, writing)

Hey, thank you for reporting this bug, sadly I cannot reproduce it. Given your emacs version (28), I suspect that this is an issue with the new version of the map.el (2.1). Could you please check the version of your map.el (by typing SPC h p map)?

[felko]

Ok, I managed to reproduce it by installing map.el version 2.1, so that's probably what's happening here. I just pushed an attempt at making neuron-mode forward compatible with map-2.1, can you give it a try now (by running doom update)?

[carlos-cardoso]

I tried doom update and It's fixed, thanks! And you were right, SPC h p RET map showed that I had version 2.1.

Great! Thank you
