I want to read the output of a buffer after process started by comint finishes.
(comint-redirect-send-command-to-process
command-string ;; tested to work in the commint buffer
output-buffer-name ;; random text
buffer-process ;; (get-buffer-process (current-buffer))
nil ;; don't echo input back
t) ;; don't show output buffer immediatly
This sexp is evaluated in a buffer running a comint process. I want to read all the text of output-buffer-name once the process has finished.
I have tried applying the solution posted to this question: sleep in emacs lisp by adding this below the process start command:
(defun on-status-change (process status)
(message "status done"))
(set-process-sentinel buffer-process 'on-status-change)
This message does not appear in *Messages*.
There is no prompt in the output-buffer text, but I can write a function that returns t when the output is finished based on the full output text.
How can I react to the buffer finishing/changing, or how can I force comint to run this function synchronously.
