Re: [STUMP] Using run-or-raise to manage pre-configured windows inatmux session

Alexander,

This is from my .stumpwmrc. Perhaps something like this works for you too.

(defcommand emacs-in-tmux () ()
  "attempts to switch to an emacs instance run in a tmux window
   called 'emacs', itself inside a urxvt instance."

  (let ((ret
 (run-shell-command "tmux select-window -t emacs ; echo $?" t)))

    (if (eql (elt ret 0) #\0)
        (run-or-raise "urxvt" '(:class "URxvt"))
        (message "no tmux session found."))))
(define-key *root-map* (kbd "C-e") "emacs-in-tmux")
