Dear org-mode community,
I use org's clocking facility to clock all my working time. I
frequently find myself clocking time for a task T1, but later realise
that I actually spent part of this time on some other task T2. In such
a situation I go to the corresponding CLOCK: line for T1, split the
interval clocked, e.g. from
CLOCK: [2015-03-30 Mon 16:27]--[2015-03-30 Mon 16:30] => 0:03
to
CLOCK: [2015-03-30 Mon 16:28]--[2015-03-30 Mon 16:30] => 0:02
CLOCK: [2015-03-30 Mon 16:27]--[2015-03-30 Mon 16:28] => 0:01
and move one of the two lines to the LOGBOOK of task T2.
The following function now automates the task of splitting:
--- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< ---
(defun org-clock-split-current-interval ()
"If this is a CLOCK line, split its clock time interval into two.
t the current time interval be A--C; then this function interactively
prompts for a time B (suggesting A as a default), and then replaces A--C
by B--C and A--B. The point is left on the line B--C, so that this line
can, e.g., be moved to another entry."
(interactive)
(save-excursion
;; Part of the following code is copied from
org-clock-update-time-maybe.
;; If this function becomes part of org-clock.el, some refactoring
would be in order.
(beginning-of-line 1)
(skip-chars-forward " \t")
(when (looking-at org-clock-string)
(let ((re (concat "[ \t]*" org-clock-string
" *[[<][^]>]+[]>]-+[[<][^]>]+[]>]"
"\\(?:[ \t]*=>.*\\)?")))
(when (looking-at re)
;; duplicate current line (resulting in A--C newline A--C)
(let ((current-line (thing-at-point 'line t)))
(when (or (= 1 (forward-line 1)) (eq (point) (point-max)))
(insert "\n"))
(insert current-line))
;; interactively change start time of the later interval
;; (resulting in B--C newline A--C)
;; TODO when universal-argument is provided, we might
alternatively offer changing the end time of the earlier interval,
resulting in A--C newline A--B.
(forward-line -2)
;; we currently assume that all timestamps in clock intervals
are inactive
(search-forward (concat org-clock-string " ["))
;; TODO call org-time-stamp with arguments that are conditional
on whether an active or an inactive timestamp was found above
(call-interactively 'org-time-stamp-inactive)
;; If there were a function that implemented the actual body of
org-clock-update-time-maybe, we could call that function, as in this
context we _know_ that we are on a CLOCK line.
(org-clock-update-time-maybe)
;; copy changed time and also make it the end time of the
earlier interval
;; (resulting in B--C newline A--B)
(re-search-backward org-ts-regexp-both)
(let ((ts (match-string 0)))
(move-end-of-line 2)
(when (re-search-backward org-ts-regexp-both nil t)
(replace-match ts))
(org-clock-update-time-maybe)))))))
(define-key org-mode-map (kbd "\C-cs") 'org-clock-split-current-interval)
--- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< ---
As I said in my previous email:
I would even be happy to contribute it to the codebase of org-mode (core
or contrib); however in this case someone would have to point me to a
fool-proof guide for how to do this. I know that for contributing code
I will have to sign some FSF copyright forms, and I know how to use git,
but I don't know the exact org-mode specific steps of doing so.
Cheers,
Christoph

One little thing, though. When I interrupt the function with C-g at the prompt, the current line is already duplicated. It would by nice that C-g left the buffer unchanged.
But other than that, this is a godsend for sloppy time-loggers like me.
Cheers,
Peter.

thanks for your feedback!
I have now made a few improvements but not yet found time to get started
with contributing the code to Worg, so one more email with the
improvements.

Done, see code below. Plus, the function now accepts a prefix argument
and works with active time stamps. When a prefix argument is given, the
interactive editing of the timestamp uses C as a default before changing
A--C into A--B B--C.
Cheers,
Christoph

This is really useful for me too. Thank you.
