So to me this looks like a bug in org-cut-subtree. Hmm I don't consider that a bug. It's documented behavior for kill commands to append to the last kill when called successively. ,[ C-h f kill-region RET ] | [...] | Any command that calls this function is a "kill command". | If the previous command was also a kill command, | the text killed this time appends to the text killed last time | to make one entry in the kill ring. | [...] ` To get a better feel for what's happening, I'd suggest evaluating kill-region with C-u C-M-x and stepping through its execution. In addition to what Samuel posted, another way for a lisp caller to avoid the append behavior if desired is to let-bind this-command so that kill-region's attempt to set it to kill-region doesn't work. Using your example, that'd be #+begin_src emacs-lisp (defun temp () (let (this-command) (org-cut-subtree)) (org-forward-heading-same-level 2) (org-paste-subtree)) #+end_src -- Kyle
Re: [O] Equivalent of timeline?
i was going to code the following, and documented it first,
but cannot code it. maybe it
will be of smoe use in thinking about the problem.
i would use text search view, as follows.
i think it should be pretty small.
===
i think timeline (L) was retired from org because it
code-rotted as org developed new features, and it only
supported one file, which goes against org's sylvan (forest)
philosophy.
it occurred to me that text search could replace the
timeline agenda view. the search is for limiting. it is not to
search for timestamps. yet the whole thing shows every timestamp.
===
it would cover most features. it would not be limited to
one file unless you restrict the agenda. it would be
relatively fast. and you can limit by searching.
however, it would not provide the shifted (left/right) arrow
feature to change timestamps.
===
the thing is to show MULTIPLE timestamps as multiple lines
in text search view.
each has a text property that contains the timestamp that
generated it. then we show the timestamps in the agenda
prefix.
text search view will show multiple timestamps per entry as
one entry, which is not what we want.
so we have to work around that.
===
there is a variable that is pretty late in the agenda view.
it is intended for things like removing entries or modifying
entries before displaying. it can be used for sorting
purposes and so on.
but i suspect we can add entries.
this would be the key insight.
===
org-agenda-skip-additional-timestamps-same-entry seems to be
only for the timestamp agenda, which we would not use.
===
you can make it cover planning (c, d, s), active/event,
inactive, clocking, notes, and state changes timestamps.
(provided that you have set a variable to show inactive
timestamps -- this works but is a defvar -- and have log
mode enabled.)
however, it would not automatically generate instances of
repeaters that are not already existing. it also would not
automatically generate internal dates within ranges (i don't
know if it would catch the endpoints, as that depends on org
internals.)
those don't seem critical for a first pass. perhaps org
support could make it do those if it is really needed.
===
basically it looks like this as a custom command.
(";" "text search -- sorted by time" search "" ( ;; can put
date in a longer org-agenda-prefix-format ;; sort on the
org-supported text property timestamp ;;
(org-agenda-cmp-user-defined #'alpha-org-agenda-cmp--time)
(org-agenda-sorting-strategy '(user-defined-up
if you want to filter by a text search, you enter that; if
not, you enter . (or maybe nothing) to show all.
filtering allows you to answer questions like "when were all
the times i mentioned "org-mode?" "which was the first time
i mentioned 'org-mode' that is significant?" which seems
more useful than a huge slow list of every timestamp in your
agenda and agenda text search extra files.
===
fwiw
Re: [O] Links to LaTeX equations
Org-ref provides a ref link for exactly this purpose. It looks like
ref:an-equation and if you click on it it jumps to the label. The link is
red if the label doesn't exist and maroonish if it does. It exports in
latex as \ref{an-equation}. It sounds like just what you need.
You can get org-ref on melpa.

Why don't you define the link in Org?
#+NAME: eq:foo
\begin{equation}
foo
\end{equation}
-k.

And why are the obvious solutions not those that come to mind (for
me)
Many thanks. Nothing in the documentation to even suggest this
possibility. That's my excuse. :)

[O] Equivalent of timeline?
I recently had to make a document listing my professional activities (lectures and performances). Items are dated. I would like to see an overview of them, sorted by date. In the past I would have used a Timeline agenda for this, but that's no longer possible. https://www.reddit.com/r/orgmode/comments/7hps9j/rip_orgtimeline/ provides a custom agenda command that is supposed(?) to mimic the old timeline, but it didn't. So how does one do it? hjh

Hi Samuel On Thu, Jun 27, 2019 at 11:57 PM Samuel Wales wrote: > does (kill-new "") in front of the kill fix it? Good idea. Yes, it prevents reinsertion of "1". Same with (setq kill-ring nil) in front of org-cut-subtree. With your idea I debug printed kill-ring and found that after the second invocation of org-cut-subtree during ~M-: (temp) RET M-: (temp) RET~ it consists of only one list element with a string containing both 1 and 2 instead of one list element with only 1 and another with only 2. So to me this looks like a bug in org-cut-subtree. Michael
[O] Links to LaTeX equations
Hello all,
it's that time of year where I have to think about revamping my lecture
slides (having just finished one year, the next one starts...). I write
these in org and export to beamer obviously!
I teach a technical subject. I therefore have quite a few equations in
my slides and I use LaTeX for these. I would like to be able to use org
fully with respect to links and targets. If I define a label in LaTeX
directly, \label{an-equation} for instance, I get no benefit from using
an org link to it, e.g. [[an-equation]] (by default, this leads to the
org exporter complaining about a missing target and if I tell org not to
complain I subsequently miss real errors). So I use inline LaTeX to
provide the link, as in \ref{an-equation}. But then I lose the ability
to jump to the target within org, something which is quite useful given
that I have many slides for the full module I teach.
The only satisfactory solution I have found is to do something along
these lines:
#+begin_src org
The equation is:
,#+begin_equation
<>
y = x + 3
,#+end_equation
(later) In equation [[an-equation]], we see nothing much.
#+end_src
This works in that I can jump to the label by clicking on the link but I
lose the ability to edit the equation in LaTeX mode.
Any pointers would be welcome.
Thanks,
eric
