Subject: New version which is compatible with emacs 24: New function to view your notes in chronological order
Date: Fri, 22 Jul 2011 20:43:06 +0200 [thread overview]
Message-ID: <4E29C4BA.5090906@online.de> (raw)
In-Reply-To: <4E22A556.3010202@online.de>
Hello !
Unfortunately, org-find-timestamps as posted before was not compatible with emacs 24.
(More precise, it hat problems with the read-only property, that emacs 24 applies to text within the occur-buffer)
The version below is now compatible with both emacs 23 and 24.
Have fun !
with kind regards, Marc-Oliver Ihm
(defun org-find-timestamps ()
"Find inactive timestamps within a date-range and maybe sort them.
This function can help to bring the notes, that you take within
org-mode, into a chronological order, even if they are scattered
among many different nodes. The result is somewhat like a diary,
listing your notes for each successive day. Please be aware
however: This intended usage requires, that you routinely
insert inactive timestamps into the notes that you write.
org-find-timstamps works by creating a regular expression to
match a given range of dates, doing a search for it and
displaying the results either as a sparse tree or with the help
of occur. The original buffer is not modified.
