Xterm Control Sequences in PROMPT

Xterm Control Sequences in PROMPT

[Teodor Knapik]

Hi,

I am running zsh-3.1.9 under Linux (Mandrake 7.2)
on an i686 and I would like to put a control
sequence for xterm, namely, "ESC ]2; <something> BELL"
in the propmpt, in order to write <something>
to the title bar of the window. Unfortunately,
it makes troubles with the line editor
(I am in emacs mode).

Could you, please, inform me in the case someone
fixes the bug for a future release ?

Best regards,
			Teodor

Hm, why don't you just set the xterm title from precmd?

precmd() {
   print -n "whatever you want"
}

Sequences in the prompt which don't cause cursor movement need to
be enclosed within %{ and %} sequences.  See "PROMPT EXPANSION"
in the manual.  Also, the proper sequence terminator is 0x9c (8bit)
or ``ESC \''  0x1b 0x5c (7bit).  BEL (0x07) is not a standard
terminator.
You may also look at  precmd() or similar as an alternative to using
the prompt.

No, nobody's going to bother replying to invalid email addresses.
