As far as I understand the docs, the string between the %{...%} should
not move the cursor in any way - I'm not sure if your sequence moves the
cursor or not (I haven't really looked: this is a quickie mail), but
this is worth checking in detail.

I don't set my titlebar in this way; I use this method:

One of the features of zsh is the precmd function which gets run before
the prompt is printed.

In my precmd function I call another function called title:

function precmd () { 
	title Zsh
};

function title () 
{
	case $TERM in
		iris-ansi*)	print -n -P "\2201.y$* ~ $USER@%m:%~\234\2203.y~ %m:%~\234\2203.y$USER@%m\234" ;;
		xterm*)	print -Pn "\e]2;$* ~ $USER@%m:%~\a\e]1;$USER@%m\a" ;;
	esac	
}

this sets my title for me on both xwsh and xterm.

My prompt variable looks like this:

CSI='^[['
prompt="%{${CSI}0m%} %(18328#::%{${CSI}32m%}%n )%{${CSI}35m%}%m %{${CSI}31m%}tty%l %{${CSI}33m%}~ %{${CSI}36m%}%h %{${CSI}35m%}%03. %(?::%{${CSI}32m%}%? )%{${CSI}0m%}> %(#.#.)"

Where 18328 is my numeric userid. 

Note that the ^[ is actually a quoted ESC put in by vi : I can't
remember if I managed to get it working with \033, but I'd guess not
judging by that ESC :)

Sorry I haven't explained much, but I've gotta go - no doubt some of the
other readers of the list will go into more detail...

This is not entirely wrong.  I suggest that the prompt code should
probably accept `%033' as having the same meaning as print's `\033'.
And I may well implement this, it being fairly trivial.

Then you should probably remove the following text from answer to
question C8 of the FAQ:

  Arguably the prompt code should handle `print'-like escapes.  Feel
  free to write this :-).

They would be trivial, but I do not recommend doing it because it would
break things.  % is the only special character in PS1, and it is good
to keep the rule this simple.

What is the issue with these anyway?  I'd think them trivial to code,
given all the other stuff Zsh contains.

The %{...%} is working just fine.  The problem is sequences like "\033",
which have no special meaning in PS1.  You need to put a literal escape
character into PS1.

Subject: [3.1.1-beta] bug with %{...%} ?

Hi everyone,

Using the Jan. 28th version of 3.1.1-beta, I've tumbled on something I
think may be a bug. It also happens with the previous version I compiled
(3.0.2).

In brief, it seems that %{...%} is not working properly inside PS1.

In tcsh, I use

set prompt="%{\033]2;%n@%M:%/ - %l\007\033]1;%l@%m\007%}%h [%T] %B%n%b@%m:%B%.2%#%b "

to set my xterm icon name & title and prompt.

If I try to use the same kind of strings for zsh, the %{...%} doesn't seem
to be really interpreted as I'd expect and I get this:

\033]2;roberto@keltia.freenix.fr:/build/zsh-3.1.1 - p2\007\033]1;p2@keltia\007203 [20:14] roberto@keltia:zsh-3.1.12% 

Is this a bug or did I miss somewhere in the documentation (I've read it)
the correct way to use "%{...%}" ?

If this is fixed in a later version, I'll upgrade of course.

Thanks,

PS: I'm not on the list so please remember to me put in Cc:, thanks.
