Hi List,
I have three questions wrt `post-command-hook':
- Is `post-command-hook' triggered when an interactive function is
called non-interactively?
- If not, what would be the equivalent hook for `funcall`, i.e. the
Emacs 'post-funcall-hook'? I could not find one. Many functions
change or insert, but some just move point, so using a post change or
post insert hook would not cover all cases (or would moving point
trigger a post change hook?).
- When is `post-command-hook' triggered? When I (e.g.)
`call-interactively' an Org command in a temporary Org-mode buffer,
and a function that exits that temp-buffer was added to the local
`post-command-hook', I would expect that once the Org command is
done that 'exit' function is called. But instead the temp buffer
still sits there, and its my next user action (e.g. typing C-n) that
then triggers the hook and calls the 'exit' function. So it seems
`post-command-hook' is triggered when another command is called, not
when current command returns control?

cheers,
Thorsten

No. It's not even run when you do (call-interactively 'foo).
It's run by the command-loop (which does: read-key, lookup-command, run
pre-command-hook, run command, run post-command-hook, ...).
What are you trying to do?
Stefan

There's no hook for all function calls. That would be way overkill.
If you want to do something after a specific function, advise it.

ok, thanks.

I wanted to call a function in a temp-buffer and then close that temp
buffer after the function/cmd is done. And it seems to work now without
using any hooks, just by sequential functions calls (as expected).
I suspect the reason it did not work yesterday has to do something with
the function/cmd that was actually called, not sure though what it was.
So this question was kind of noise, sorry.

Are you aware of the macro `with-temp-buffer'? :-)

yes, but things are a bit more complicated ...
