• Have made my function tjh/org-roam-open-node-by-id support opening an Org id, which corresponds to a task in one of my Org agenda files, but is not included in my Org Roam note system. With a given id, this function first tries to acquire an Org Roam node with org-roam-node-from-id. If a node is found, use org-roam-node-visit to jump to this node. If it cannot be found, org-id-goto will be used to navigate to an Org task. N.B. The file to which this Org task belongs should have been registered as an agenda file, i.e. in the list org-agenda-files.

    (defun tjh/org-roam-open-node-by-id (id)
  "Open an Org Roam node id or a normal Org id"
  (interactive "sNode id:")
  (let ((node (org-roam-node-from-id id)))
    (if node (org-roam-node-visit node)
      (org-id-goto id))))

    Then I can connect my mindmap nodes with either an Org task or an Org Roam node by adding the roam://<org-id-or-org-roam-id> link as an attribute. In the same way, I can also link my Anki cards with Org task or Org Roam.

  • I use Joplin markdown note to grab web pages and capture flashing ideas using voice input when I am walking or travel outside, so I need to copy markdown text directly into Emacs Org. The following script do this job. It uses gui-get-selection to acquire the contents in the clipboard. Then a temporary buffer is created with with-temp-bufer. The clipboard contents will be inserted into this buffer and then be processed by pandoc. Finally, the postprocessed contents are collected by buffer-string and inserted into the current buffer.

    (defun tjh/paste-markdown-to-org ()
  "Convert the markdown contents in the clipboard to Org format then paste into the current buffer."
  (interactive)
  (let ((md (gui-get-selection 'CLIPBOARD)))
    (when md
      (let ((org (with-temp-buffer
		   (insert md)
		   (call-process-region (point-min) (point-max) "pandoc" t t nil
					"-f" "markdown" "-t" "org" "--wrap=none")
		   (buffer-string))))
	(insert org)))))
