bug#5255: 23.1.90; Wrong prompt in term

[Fabian Ezequiel Gallina]

In emacs 23.1 when I use M-x term the prompt is rendered correctly to
whatever is defined on the PS1 environment variable. But in 23.1.90.1 it
prompts whatever is defined in the PS1 but also before that, it prompts
0;<user>@<host>:<location>.

The steps to reproduce it are quite simple:

emacs -Q
M-x term

The prompt is rendered like this:

0;fgallina@cuca:~/Builds/emacs[fgallina@cuca emacs]$

Since my PS1 is set to

PS1='[\u@\h \W]\$ '

the expected result is:

[fgallina@cuca emacs]$

I can't reproduce this.
Are you sure that your prompt is set to what you show there?  Maybe the
system default sets it to something else?

I guess I found the problem:

[fgallina@cuca lisp]$ env | grep PROMPT_COMMAND
PROMPT_COMMAND=echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\007"

Now the thing is that executing this in a normal terminal renders
nothing, as opposed to term. My guess would be that term is missing
the \033] escape sequence.

That looks like a bad idea.
I am guessing that you are trying to set the xterm title to display the
current directory in the shell, this uses an xterm specific escape sequence.
So it should only be done for xterm.

But you should not need to use PROMPT_COMMAND to do this, it can be done
by just setting the prompt, search the web for something like: "bash
prompt xterm title"

It's actually \033];STUFF\007.

Yes, it is used just for that, I found this which explains the thing:
http://www.faqs.org/docs/Linux-mini/Xterm-Title.html#ss3.1

I didn't set up it myself, I guess xterm sets this automatically.

Oh yes, actually that is not being taken into account and I guess it
should, at least that's what happens in emacs 23.1.

The explanation is not very clear, it actually shows how this can be
done by using just PS1 and not PROMPT_COMMAND...
And it's shown that is should only happen when TERM is xterm.

xterm does not do things like that.
Your system does it then, and it's wrong, it should only do it if TERM
is xterm.

This is an xterm specific escape sequence, most likely due to a bad
setup, you'll get the same problem if you use a vt100 terminal for
example.  
So this is not a term.el problem.

Thanks for the explanation, I just added this to my .bashrc and
everything started to work fine again:

if [[ $TERM =~ ^xterm ]];
then
	TERM=xterm-256color
	PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\007"'
else
	PROMPT_COMMAND=""
fi

However what really surprises me is that emacs 23.1 didn't got the
prompt wrong with my old PROMPT_COMMAND.

Changing the value of TERM is a bad idea, unless you know exactly what
you are doing.

  > 	PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\007"'

Using PROMPT_COMMAND is not a good idea, the same thing can be done with
just setting the prompt.

Odd, indeed.  If you could try and investigate further to try and figue
out what caused the change, it would be helpful.

    I am closing this bug, it's not a bug in term.el

    Changing the value of TERM is a bad idea, unless you know exactly what
    you are doing.
