Journal

Stepped away, played with Obsidian Canvas some more, and then had the idea to convert this to a much simpler idea: Serve org-roam nodes as HTML to Obsidian.

2023-06-04

  • switched to pnpm because unlike npm, it does not mind the symlinked node_modules

2023-05-29

  • fixed emacs comms and factored out (see emacsclient quoted values) note below
  • managed to create an unfilled org-mode note via UI

emacsclient returns quoted return values :(

After spending too many hours debugging / trying to work around this, I run into this fix: https://github.com/grettke/ebse

Unfortunately, it has to run a new emacs server from batch mode. At least it has some verbose explanation of what I'm seeing.

Use emacsclient to pipe to emacs for unquoting, but also a pattern to dump json! https://www.reddit.com/r/emacs/comments/asil1y/batch_processing_and_printing_to_stdout_using/

I had to modify that (left comment on the reddit) to get it working on Emacs 29:

emacsclient --eval '(princ "foo\n")' | emacs -Q --batch --eval '(progn (insert-file-contents "/dev/stdin" nil nil 65536) (princ (read (buffer-string))))'

note the 65536 value for END, else it errors out with "Maximum buffer size exceeded"

switch to org-roam node via emacsclient

# this will return the node objects representation
emacsclient -c -eval '(progn (org-roam-node-find)(org-roam-node-at-point))'
(cl-defstruct (org-roam-node (:constructor org-roam-node-create)
                             (:copier nil))
  "A heading or top level file with an assigned ID property."
  file file-title file-hash file-atime file-mtime
  id level point todo priority scheduled deadline title properties olp
  tags aliases refs)
# spit out id, title, file
emacsclient -c -eval '(progn  (org-roam-node-find) (let ((node (org-roam-node-at-point))) (format "id:%s\ntitle:%s\nfile:%s" (org-roam-node-id node) (org-roam-node-title node) (org-roam-node-file node))))'

return html version of org-roam node

;; if heading then export subtree only (SUBTREEP), else export buffer
;; body-only does not render the title, which is why we do the whole thing, then extract the body instead
(let ((fnpos (org-roam-id-find "31dbd0e2-e881-4240-917a-2468cb23a5b5")))
  (when fnpos
    (with-temp-buffer
      (insert-file-contents (car fnpos))
      (goto-char (cdr fnpos))
      (let* ((node (org-roam-node-at-point))
             (html (org-export-as 'html (org-at-heading-p) nil nil))
             (start (cl-search "<body>" html))
             (end (cl-search "</body>" html))
             (body (substring html (+ start 6) end)))
        (format "title:%s
file:%s
%s" (org-roam-node-title node) (org-roam-node-file node) body)
        ))))

react-embed looks pretty amazing

... but youtube refuses to render over here. See BUG below.

BUG: react-embed youtube briefly shows and then disappears

based on errors in my console:

On react-youtube issues they claim that this does not affect the appearance of the widget, but on my side it does.

With mkcert I installed locally trusted certs, but even with https://localhost access, still the same postmessage error, on no youtube video that appears.

Using the underlying https://github.com/tjallingt/react-youtube directly gives the same behaviour.

Embedding of e.g. <Embed url={"https://soundcloud.com/kink/mechtaya"} /> does work.
