bug#57821: 29.0.50; ANSI sequence not filtered in compilation buffer


From: Matthias Meulien
Subject: bug#57821: 29.0.50; ANSI sequence not filtered in compilation buffer
Date: Thu, 15 Sep 2022 10:24:15 +0200
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/29.0.50 (gnu/linux)

Under the hypothesis of a host with Python installed with poetry,
pre-commit tooling and flatpak builder:

1. Start 'emacs -Q'

2. Clone the Git repository https://github.com/orontee/argos and install
   pre-commit hooks as described in the CONTRIBUTING guide

3. Visit a file in the directory containing the cloned repository

3. C-x p c poetry run pre-commit run -a RET

4. Rename buffer (C-x x u)

5. C-x p c flatpak-builder --user --install --force-clean builddir
   io.github.orontee.Argos.json

Observe that the first compilationbuffer doesn't show any ANSI sequences
but the second displays many ^G^[ char sequences:

With `ansi-color-compilation-filter' added to `compilation-filter-hook',
the situation is the same:

Again same situation when running both commands from a shell buffer.

But with `comint-osc-process-output' added to
`comint-output-filter-functions' then everything looks good.  It seems
that flatpak-builder outputs OSC sequences and ANSI sequences.

Is there a way to filter out (or render) OSC sequences from compilation
output buffers as is possible for comint output?
