modeline clock string

modeline clock string

[Yuri Goncharov]

I use xmonad with xmobar at my desktop. I'd like to add clock
string from mode line to xmobar. Is there  way to save it to
file every time when update mode line?

You can find information on various subjects with M-x apropos but it's
sometimes hard to find the right keyword. I emacs, certain functions
are called when certain events occur, those functions are called
hooks. I found display-time-hook by doing M-x apropos<ret>hook<ret>
and then searching for status (no result) and update (which yielded
display-time-hook).

See documentation of variable display-time-hook

Thanks to answer! I need some more help, because my knowledge of lisp
too poor. I found two hooks like I need org-clock-in-hook and 
org-clock-out-hook. Function  org-clock-get-clock-string returns string
that is showing in mode line. I cant figure how to write it in file.
Apologies to my english.

Maybe this will help:

--8<---------------cut here---------------start------------->8---
;; ---------------------------------------------------------------------------- DISPLAY-TIME
(display-time)
(defun esf/org-clocking-info-to-file ()
  (with-temp-file "~/tmp/clocking"
    ;; (message (org-clock-get-clock-string))
    (if (org-clock-is-active)
	(insert (format "org: %d/%d min" 
			(- (org-clock-get-clocked-time) org-clock-total-time)
			(org-clock-get-clocked-time))
		)
      ) ;;(org-clock-get-clock-string)
    )
  )
(add-hook 'display-time-hook 'esf/org-clocking-info-to-file)
--8<---------------cut here---------------end--------------->8---

I use this to place information on clocking at the top of my display
(using dzen2 with ratpoison).  I have minimal space so only include
the time information, not the full information which typically
includes the org-heading being clocked.

This doesn't work properly if you have two emacs instances but I can't
be bothered to improve it as I *never* have two or more emacs
running...  that's what emacsclient is for, after all... ;-)

HTH,
