this package is too complex for me ...

It's work, Now I use function like this:

#+begin_src
(defun escape-instance-name (str)
  (let (buf)
    (map nil #'(lambda (ch)
                 (if (or (char= ch #\()
                         (char= ch #\))
                         (char= ch #\")
                         (char= ch #\ ))
                     (push #\_ buf)
                     (push ch buf)))
         str)
    (coerce (reverse buf) 'string)))

(defun emacsclient-eval (&optional expression create-frame frame-name file)
  (let ((name (or frame-name
                  (escape-instance-name expression))))
    (run-or-raise
     (concat "emacsclient --server-file=default "
             (when create-frame (concat "-c -F '((name . \"" name "\"))' "))
             (when expression (concat " --eval '" expression "'"))
             file)
     (list :instance name))))

(defcommand org-capture-contacts () ()
  (emacsclient-eval "(progn (kill-new \"\") (eh-org-capture nil 
\"contacts\"))"))

#+end_src

I don't like  write sexp string, for example "(progn (kill-new \"\") 
(eh-org-capture nil \"contacts\"))"
to my stumpwmrc, which will used by emacsclient as --eval argument.

I find
(string-downcase
          (prin1-to-string
                '(progn (kill-new "")
                        (eh-org-capture nil "contacts"))))

get "(progn (kill-new \"\") (eh-org-capture nil \"contacts\"))"
and the first one is much cleaner for me ...
