This appears to be buggy behavior, but I'm asking here first in case it might
already have been fixed.
A couple of months ago, I was trying to create a repeating timestamp for two
different days of the week. First I tried a diary-sexp, but that wasn't
compatible with habits, so I gave that up. But I didn't want to throw away the
string completely, because it took some digging to figure it out. So I put "# "
at the beginning of the SCHEDULED line and thought that would be the end of it.
(In the source block, "#" has two spaces before it. These come from C-c '
editing. In my original file, the "#" for the comment is flush left.)
#+BEGIN_SRC org
,** TODO Update lesson grades 2 :Comp:
SCHEDULED: <2014-12-06 Sat 23:59 .+1w>
:PROPERTIES:
:STYLE: habit
:LOGGING: TODO MAYBE INPROG MTG | DONE(!) POSTPONED CANCELED
:END:
# SCHEDULED: <%%(memq (calendar-day-of-week date) '(3 6))>
#+END_SRC
Just now, I tried to open a sparse-tree view with a scheduled date range -- C-c
/ c c D (set range) -- and got the message:
byte-code: Bad timestamp `%%(memq (calendar-day-of-week date) '(3 6))'
Error was: (Not a standard Org-mode time string: %%(memq (calendar-day-of-week
date) '(3 6)))
This is the only occurrence of memq anywhere in this org file, so it *must* be
coming from this line. So, whatever regexp is handling scheduled timestamp
searches doesn't check whether the line is a comment or not.
There may be a valid reason for this behavior, but I tend to think a comment
should always be a comment.
