[emacs-berlin] `server-eval-at' turns out to be pretty useful...

[Tilmann Singer]

I might be missing something obvious, but what exactly is it that
emacsclient can not do? With a running Emacs instance in which
(server-start) has been called before, the following commands on a
terminal with the bash shell work out of the box for me:

$ emacsclient -e "(+ 1 1)"
2

$ printf "How many is binary? $(emacsclient -e '(+ 1 1)')\n"
How many is binary? 2

$ emacsclient -e 'emacs-version'
"27.2"

$ emacsclient -e '(with-current-buffer "*scratch*" (insert "Hello scratch buffer"))'
nil
=> Text was inserted into buffer *scratch*


At least on this (arch) linux machine, the default server-socket-dir of
"/run/user/1000/emacs" seems to be working fine.
