In this concrete case, I am looking for a way to make Emacs not wait
for, or at least not process, input from a specific process while
sending output to a different process.
For the case I posted, I can alleviate the issue a bit if I set:
(setq max-specpdl-size 5000)
However, if I then use for example the following definition of
send-to-target instead of the one I posted:
(defun send-to-target (proc str)
(if (process-live-p target)
(process-send-string target str)
(kill-process source)))
then I get, for the receipe I posted:
Lisp nesting exceeds ‘max-lisp-eval-depth’
This is unfortunate, because increasing this limit will eventually crash
Emacs. The root cause is that process-send-string triggers the filter of
the same process that caused the filter to be invoked. I find this
unexpected, because the target process is different, and if possible, I
would like a way do prevent this. Could you please consider adding a
feature that prevents triggering the filter in such cases?
Thank you and all the best!
Markus
