bug#2400: 23.0.90; shell-mode: garbage in prompt

[Xavier Maillard]

My prompt is rendered with garbage like this:

^[]0;xma@zogzog:~/var/spool/mail\a^[]0;xma@zogzog:~/var/spool/mail\a[xma@zogzog 00:36:00 mail]$ 

It happens with emacs -Q

Steps to reproduce:

M-x shell RET
M-x load-library RET ansi-color RET
M-x ansi-color-for-comint-on RET

Reproducible: always

I can't reproduce this.  What is the $PS1 setting for your prompt?  And
does this bug occur in Emacs 22?

These don't look like color escape sequences.  So the problem is most
likely in your prompt.

Here is the definition of my PS1 variable:

\[\033]0;\u@\h: \w\007\]\[\033[0m\033[0;1m\][\[\033[0m\033[0;32m\]\u@\h \[\033[0m\033[1;34m\]\t \[\033[0m\033[0;36m\]\W\[\033[0m\033[0;1m\]]\[\033[0m\033[0;37m\]\$

The weird thing is the line above the prompt. My prompt is no
more than [xma@zogzog 00:36:00 mail] here.

Regards,

	Xavier

It occurs both on Emacs 22 and Emacs 23.

As for the PS1 value, see my other post.

That's its value, not its definition.  Where do you set it and how?

This does more than just set your prompt and colour it.
It also sets the xterm title to "user@host: pwd".

man console_codes:

   ESC ] 2 ; txt ST        Set window title to txt

This is not an ANSI colour escape sequence and so is not handled by
ansi-color. It's not appropriate to use such a PS1 setting on something
that is not an xterm. For example, it also messes up on the Linux
console.

I meant to quote:

  ESC ] 0 ; txt ST        Set icon name and window title to txt.

which comes from the xterm-specific section of `man console_codes'.
