Re: How to avoid loading file when just testing if function

[Buchs, Kevin]

Sebastien,

For the purpose you specify, how about checking what org-mode checks to
determine if there is an active clock? In the end, it simply looks for
an org-clock-marker to exist, i.e. be non-nil. (if org-clock-marker
(...)). You may be interested in the general question for any situation,
how to test whether some autoloaded function has been loaded or not.

Hi,

For the purpose of asking whether I eventually need to clock out (from
Org) before exiting Emacs, I've written this chunk of code:

--8<---------------cut here---------------start------------->8---
  (if (and (fboundp 'org-clocking-p)
           (org-clocking-p)
           (y-or-n-p "You are currently clocking time, clock out? "))
      (org-clock-out)
    t))
--8<---------------cut here---------------end--------------->8---

The problem is that if Org is not yet loaded, the above code does load
it (because `org-clocking-p' is autoloaded) -- and that takes a while...
and I just wanted to exit Emacs...

How to avoid this?

Best regards,
  Seb
