In org-mode..

I store lots of state-change messages and timing info in the LOGBOOK drawer.

Most of the time, I don't look into the LOGBOOK drawer, but once in a while when following up on a pending task, I peek into the LOGBOOK drawer to see my note.

I'm looking for a quick-way to expand the drawer using TAB on the head-line. Currently, 1st tab expands the entry, 2nd tab expands entry + subentry but not the LOGBOOK drawer.

Ideally, I'd like to:

  1. First tab expands the entry,
  2. Second tab expands sub-headings including LOGBOOK drawer (but not PROPERTIES or other drawers).

So I'm trying to tie in a function into the org-cycle-hook, but I have an issue:

(defun my/expand-logbook-drawer ()
 "Expand the closest logbook drawer"
 (search-forward ":LOGBOOK:")

(add-hook 'org-cycle-hook
  (lambda (my/var/curr-state)
    (message "State changed")
    (when (= my/var/curr-state "all")   ;This comparison doesn't work, error: wrong argument, number-or-marker-p

It seems my comparison function doesn't work. Thoughts?

Note, the org-mode-cycle docu is here

  • = is for comparing numbers, you probably want string-equal or just equal.

  • Then it means that my/var/curr-state isn't a string. A simple way to debug it is to put a (message "my/var/curr-state: %s" my/var/curr-state) before the offending line and after this hook fires, look into the *Messages* buffer.

  • I recommend taking a look at the function org-cycle-internal-local and insert your function at the appropriate section -- e.g., if you want your function to run when "CHILDREN" are exposed, then insert your function at that section of the code. You can create a new function to replace org-cycle-internal-local, by having it evaluated after org.el is required -- I believe the current version of Emacs loads the library on startup, so you can probably just drop your new org-cycle-internal-local into your .emacs file and away you go. I have not attempted to debug your proposed code.
