;;; Commentary:
|
|

|
|
;; We extend org-protocol, adding custom Org-roam handlers. The setup
|
|
;; instructions for `org-protocol' can be found in org-protocol.el.
|
|
;;
|
|
;; We define 2 protocols:
|
|
;;
|
|
;; 1. "roam-file": This protocol simply opens the file given by the FILE key
|
|
;; 2. "roam-ref": This protocol creates or opens a note with the given REF
|
|
;;
|
|
;;; Code:
|
|
(require 'org-protocol)
|
|
(require 'org-roam)
|
|
|
|
;;;; Functions
|
|
(defun org-roam-protocol-open-ref (info)
