zsh multiline prompt and windows lock problem

 
Hello,

I'm using xshell to connect on linux box with zsh. I have reconfigured my prompt to have a multiline prompt:

-[user@host]-[15:38]-[~]-
->

Since then, each time I unlock my windows station with xshell on foreground, the first line of my prompt get repeated two additional times. So, after unlocking, I get on the screen :


-[user@host]-[15:38]-[~]-
-[user@host]-[15:38]-[~]-
-[user@host]-[15:38]-[~]-
->

where I had previously my correct prompt.

any idea ?

Program Ver. : Xshell 3.0

EDIT: in fact, it's the case even if xshell in not the foreground app, but it's only on the selected tab, and not on the others.
EDIT: same effect in case of "Restore" or "Maximise" of xshell window

We have tried duplicating the problem but could not. If you could send us more information, we will it again. Please send us the following information:

1. Prompt string script and how it is applied.
2. Name/version of UNIX
3. What do you mean by lock/unlock?

Re: Re: zsh multiline prompt and windows lock problem

 
At the end is the zsh ressource file defining my prompt.
It is sourced in .zshrc with "source .prompt2"

It's on a SuSE Linux (Linux version 2.6.5)

By lock/unlock, I simply mean locking or unlocking my windows XP PC on which I'm running xshell to connect to the linux boxes.

JP

Re: Re: Re: zsh multiline prompt and windows lock problem

 
After a further testing, we found out that this problem is caused by zsh itself. You can see the same problem occuring under console or any other terminal emulators.

You will have to contact zsh developers to fix this problem.

Hope this helps.

[SOLVED]Re: Re: Re: Re: Re: zsh multiline prompt and windows lock problem

 
Hello,

I have found the solution in the archive of zsh users mailing list.

In fact, it is linked to the way the terminal get resized, and how it handle it.

The solution is in fact pretty simple : the first line of the prompt can be printed in the precmd function with 'print -rP "..."' and the second line is set in PROMPT variable.

This is a workaround more than a real fix, but it's working.

Hopes it could help others, even if not totally xshell related.

Regards
