Subject: comint-output-filter-functions and multi-line input
Date: Sun, 16 Oct 2022 08:48:11 +0000	[thread overview]
Message-ID: <87y1tgqhmc.fsf@localhost> (raw)

Hello,

I am trying to figure out how to programmatically capture output of a
multi-line bash script in comint buffer.

Consider:

[yantar92:/tmp] $ 
> if true
> then
> echo "hello"
> fi
hello

Each line is submitted to shell via comint-send-input and, AFAIK, the
result can be collected using `comint-output-filter-functions'.

I expect the `comint-output-filter-functions' to be called on "hello"
line. However, it does not seem to be the case. Empty "" corresponding
to "> " PS2 prompts upon sending incomplete script lines are also
passed.

Is it possible to distinguish the actual script output, empty lines in
the actual script output, and the incomplete prompts?
