shell - 我怎样才能检测到 emacs-server 正在从 shell 提示符运行？

Question

我想让我的 .bashrc 检测运行 emacsclient 是否可以代替运行 emacs。基本上:

if emacs_server_is_running; then
    EDITOR=emacsclient
    VISUAL=emacsclient
else
    EDITOR=emacs
    VISUAL=emacs
fi

我应该在 emacs_server_is_running 函数中放入什么来实现这个目标？

你太难了。来自 emacsclient(1) 手册页:

-a, --alternate-editor=EDITOR if the Emacs server is not running, run the specified editor instead. This can also be specified via the `ALTERNATE_EDITOR' environment variable. If the value of EDITOR is the empty string, then Emacs is started in daemon mode and emacsclient will try to connect to it.
