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

[Mostafa Razavi]

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")

I have one tmux session running and the following works for me:
(run-shell-command "tmux select-window -t CONTROL")

Not sure, how multiple tmux sessions will be handled.

(window-send-string "tmux select-window -t CONTROL") will only work when
you are in a shell window.

Otherwise you need to send Control-B : somehow to enter the tmux command mode.
