Hi emacs-devel,
Ubuntu has a new wrapper around apt-get and apt-search called apt. As it runs it displays a progress bar, whose ANSI escapes confuse ‘M-x shell’; here's an example:
Removing libacl1-dev (2.2.52-3) ...
^[7Progress: [ 0%] [................................................................................................] ^[8^[7Progress: [ 25%] [########################........................................................................] ^[8^[7Progress: [ 50%] [################################################................................................] ^[8^[7Progress: [ 75%] [########################################################################........................] ^[8Processing triggers for man-db (2.7.5-1) ...

And here's another one:

Is this a bug that should be fixed on the ‘apt’ side (it shouldn't show the progress bar?), or can we support these escapes?
Clément.

Maybe (not sure) we could argue that apt should be more careful before
using such codes, but we can support these escapes, I think, and doing
so would be better for the user.

What happens if you use {M-x ansi-term RET}?

I guess it would work fine, but I'd rather not use ansi-term, if possible.

The ansi-color package has a function, #'ansi-color-apply-on-region
which works well for translating these to colorized font faces (I use it
on some shell output from my own custom functions that include these
escape codes).

Hmm, I'm not sure I understand. shell-mode already translates most ANSI escapes to colorized faces, doesn't it?
For example, in emacs -Q, running M-x shell and typing `env TERM=xterm ls --color' gives me properly colored output.
AFAICT, the only thing that's missing is support for the two specific codes (61 and 62) that `apt' is using. Isn't that right?
Clément.
