One more question, in case I am using
org-roam-dailies
, which stores the tasks in individual files within a sub-folderdaily
within theorg-roam
folder, do I need to update the functionvulpea-agenda-files-update
to include thedaily
folder? Or would it be simpler to modify the capture function fororg-roam-dailies-capture-templates
to add theproject
tag?
Vulpea scans the buffer for any todo and adds the project tag automatically. It latches onto before-save hook.
(add-hook 'before-save-hook #'vulpea-project-update-tag)
(defun vulpea-project-update-tag ()
"Update PROJECT tag in the current buffer."
...
(goto-char (point-min))
(let* ((tags (vulpea-buffer-tags-get))

(setq tags (remove "project" tags)))

Hey @d12frosted Would you consider updating the gist with this
https://gist.github.com/d12frosted/a60e8ccb9aceba031af243dff0d19b2e?permalink_comment_id=4976115#gistcomment-4976115
? Or give your opinion - last time I remember it was borking pdf files from opening in emacs 29.
Thanks.
@akashpal-21 Thanks, that makes sense. I had missed it as when I was looking at my agenda, the tasks wouldn't show up, but then I realised it was because I had customized the agenda view to only show tasks with deadlines in the current week. Changing the view to all tasks with todo did indeed show up the other tasks.
@akashpal-21 updated the gist. Thanks for reminder :)
