Is there any way to insert a header and automatically a timestamp with
date/time?
I can write me a small function doing this and bind it to some unused
key, but is there a more general/elegant way I just miss?
Hi Uwe,
TL DR; I add the timestamp automatically on entry creation as a hook
[2], in fact, I have several hooks on entry creation and I think is a
good way to handle this. I am happy with my setup since I started using
it in 2023.
Let me share my experience on that topic (and very happy to hear other
experiences and/or feedback), I hope the offtopic inside is welcome and
useful:
1. Before, I was manually adding timestamp headers as a postfix for the
creation of the header (and this is how I reverted using this script per
target buffer [1]) to transform to CREATED properties (see here the
automation on how I add the timestamp automatically on entry creation
[2]), which I think are even better, specially, because then you can add
that column to your table-reports such as clocktable, org-ql, propview,
custom org-map-entries stuff.
2. After, as a prefix, in the journal files, for facilitating
alphanumeric sorting of items in my customized journal (with a structure
of year > week > day). I finally got rid of that, and brain and eyes
appreciated that movement, it is too much noise to see a lot of items
with timestamp. I discovered that problem when I started using
variable-pitch mode, which with modes themes works very nice with
(enable variable: (setq modus-themes-mixed-fonts t) ). Then,
alternatively, sorting can be done by adding "SCHEDULED" to all items
created on certain buffers and levels [3], which I also add for certain
org-agenda files (then I use schedule as a poor's man alternative to
anki [4] for space repetition [5], which could of course involve real
tasks and projects apart from the typical usecase of memorizing concepts).
I do it this way and it works fine for me since that date I use it:
