Subject: bug#61602: 29.0.60; comint-mode redirection
Date: Sat, 18 Feb 2023 12:26:19 +0100 [thread overview]
Message-ID: <873573ryft.fsf@zohomail.eu> (raw)
Dear Emacs maintainers,
I have been working on a major mode derived from comint-mode. The mode
uses redirection to show documentation in a separate buffer. Sometimes,
a prompt would appear in the output of the command producing the
documentation and this would end the redirection prematurely. Searching
among variables in comint-mode I found comint-redirect-finished-regexp
and its docstring made me believe that I could set it to change the end
of redirection. However setting it had a no effect and looking at the
sources I found that this is because it is set by comint-redirect-setup
and comint-redirect-send-command-to-process calls comint-redirect-setup
so that it is always set to comint-prompt-regexp during redirection.
This is confusing behavior because docstring of
comint-redirect-finished-regexp gives no clue that setting it will have
no effect. Similarly the docstring of comint-prompt-regexp states that
its value is only used when comint-use-prompt-regexp is non-nil but
that is not true for redirection.
Overall I think it would be nice to have an optional argument to
comint-redirect-send-command-to-process which allows a user to
explicitly pass the regexp to use for ending redirection.
Another issue I had was that I wanted to run some commands when
redirection ended. There didn't seem to be any hooks that accomplished
this but from source of comint-redirect-preoutput-filter I found that
comint-redirect-hook is run when redirection finishes. However
comint-redirect-hook is not defined as a variable and nothing seems to
give any hint of its existence.
Thanks,
Rahguzar
