Subject: bug#35129: Unsupported escape sequences for progress in shell
Date: Wed, 03 Apr 2019 23:27:24 +0300 [thread overview]
Message-ID: <87lg0qx2ab.fsf@mail.linkov.net> (raw)
Some escape sequences are unhandled in shell mode.
Most often they appear when running `apt install'
that shows its progress bar that is supposed to stay
on the same line, but spreads over several lines,
so the output looks like a mess (where ^[7 and ^[8
are escape sequences currently still unhandled):
debconf: unable to initialize frontend: Dialog
debconf: (Dialog frontend will not work on a dumb terminal, an emacs shell buffer, or without a controlling terminal.)
debconf: falling back to frontend: Readline

I'm making this report because escape sequences for colors are handled fine,
and visually these indicators have the green background.
