In PicoLisp you can define a function like this
#+begin_src picolisp
(de emc (Exe . @)
(in
(cons 'emacsclient
"-s" "my-server" "-e" (rest) )
(eval Exe) ) )
#+end_src
and then e.g. use the PicoLisp REPL to communicate with Emacs via stdin/stdout
#+begin_src picolisp
: (emc '(read) "(princ \"Hello World\")")
-> "Hello World"
: (emc '(read) "server-name")
-> "my-server"
: (emc '(line) "server-name")
-> ("\"" "m" "y" "-" "s" "e" "r" "v" "e" "r" "\"")
: (emc '(line T) "server-name")
-> "\"my-server\""
#+end_src
