The Org-roam v2 Great Migration

Development
81

I think that it would be great to have some standard configuration file for people using doom emacs.

My configuration at the moment is attached. I hope this might help other people migrating.

EDIT: I finally got the org-roam-buffer to be configured correctly on doom emacs. changed the config below accordingly.

(setq org-roam-v2-ack t)

(use-package! org-roam
  :init
  (setq org-roam-v2-ack t)
  (map! :leader
        (:prefix-map ("n" . "notes")
         (:prefix ("r" . "roam")
          :desc "Insert new roam node" "i" #'org-roam-node-insert
          :desc "Find roam node" "f" #'org-roam-node-find
          :desc "Roam buffer" "r" #'org-roam-buffer-toggle
          (:prefix ("d" . "dailies")
           :desc "today" "d" (lambda () (interactive) (org-roam-dailies-capture-today t))
           :desc "today" "y" (lambda () (interactive) (org-roam-dailies-capture-yesterday t))
           :desc "tomorrow" "t" (lambda () (interactive) (org-roam-dailies-capture-tomorrow t))))))

  (setq org-roam-completion-everywhere 'nil)
