Tiny piece of customization for ctrl-c ctrl-c within a timestamp

Tiny piece of customization for ctrl-c ctrl-c within a timestamp

[Marc-Oliver Ihm]

Hello !


I sometimes find myself adjusting timestamps just by editing its text;
e.g. changing <2010-10-16 Su> to <2011-10-16 Su>. However after that
editing, the day of week is usually wrong (or might be right, I just
dont know).

With this small piece of lisp, one just needs to press ctrl-c ctrl-c
while the cursor is in a timestamp and the day of week is adjusted.


(defun org-set-weekday-of-timestamp ()
  "Check if cursor is within a timestamp and compute weekday from numeric
date"
  (interactive)
  (when (org-at-timestamp-p t)
    (org-timestamp-change 0 'year)
    (message "Weekday of timestamp has been adjusted.")
    t
  ))

(add-hook 'org-ctrl-c-ctrl-c-hook 'org-set-weekday-of-timestamp)


Maybe someone else might find that useful too.


With kind regards, Marc-Oliver Ihm

Very useful, since I often do the same! Thanks for this.

My hack for this is S-<right> S-<left>: it advances the date up and down
by 1 but has the side effect of setting the day of the week correctly.

S-<right> S-<left> is nearly as short, and I did not think about it :-)
The only remaining advantage of my hack (besides the apparent
disadvantage of needing explicit customization) is, that it increases
the dwimity of ctrl-c ctrl-c ...

Thanx and kind regards, Marc-Oliver Ihm

Hi Marc-Oliver,



http://orgmode.org/manual/Creating-timestamps.html#Creating-timestamps

describes all you need to change timestamps without errors:

   S-<left>
   S-<right>
       Change date at cursor by one day. These key bindings conflict
       with shift-selection and related modes (see Conflicts).
   S-<up>
   S-<down>
       Change the item under the cursor in a timestamp. The cursor can
       be on a year, month, day, hour or minute. When the timestamp
       contains a time range like `15:30-16:30´, modifying the first
       time will also shift the second, shifting the time block with
       constant length. To change the length, modify the second
       time. Note that if the cursor is in a headline and not at a
       timestamp, these same keys modify the priority of an item. (see
       Priorities). The key bindings also conflict with shift-selection
       and related modes (see Conflicts).



Also, `C-c .'  while on a timestamp you may use the calendar interface
to change the timestamp.   Days of the week will be OK.
