Hi Nate,
I would probably write it like this: (but I'm no emacs-lisp expert
either)
(defun njn/agenda-toggle-show-closed()
"Toggle whether closed clock thingies are shown in the agenda"
(interactive)
(setq njn/org-agenda-show-closed (not njn/org-agenda-show-closed))
(setq org-agenda-log-mode-items (if njn/org-agenda-show-closed
(quote (closed clock))
(quote (clock))))
(message "%sShowing closed clock entries in agenda" (if njn/org-agenda-show-closed "" "NOT ")))
You have a bug in your version - the test and report is backwards.
When njn/org-agenda-show-closed is t you don't show closed items and
when it's nil you do.
- You don't need to check for equality with 't (and you don't need to
quote t)
- everything non-nil is true
- you can just check that directly in the (if ... )
My version basically does this:
1. toggle the boolean njn/org-agenda-shot-closed
2. set org-agenda-log-mode-items based on the boolean
3. report the value
HTH,
Bernt
