Subject: How to detect two emacs process in Elisp code?
Date: Fri, 17 Jul 2020 22:54:50 +0800 [thread overview]
Message-ID: <87ft9s283t.fsf@gmail.com> (raw)
I load desktop-save-mode session in init.el. But when using
"bug-hunter-init-file", I need to exclude this session init file.
Here is my try:
#+begin_src emacs-lisp
;;; detect external system has Emacs process running?
;;; If yes, like `bug-hunter' is running. Then don't load session.
;;; FIXME
(let ((emacs-processes
(length (mapcar
'string-to-number
(seq-filter
(lambda (str)
(not (string-empty-p str)))
(split-string
;; (shell-command-to-string "ps -C emacs -o pid=")
(shell-command-to-string "ps -C emacs -o pid=")
"\n"))))))
(when (<= emacs-processes 1)
(message "init-emacs-session loading")
(require 'init-emacs-session)))
#+end_src
The upper code has a problem, the command "ps -C emacs -o pid=" can't detect
emacs program name like "emacs-28.2.3" which is which is in /usr/local/bin and
compiled from source code.
Does anyone have good solution for this? Thanks in advance.
