Is there a kind of function factory in zsh?

Is there a kind of function factory in zsh?

[Leander Jedamus]

Hi!

I wonder if I could use a pattern for creating fucntions, that nearly 
look the same.
Background is I have to write a function for ssh, telnet, su, bash, zsh, 
tcsh and so on that all look like (for example for the ssh command):
ssh()
     {
       set_title "ssh $@"
       {
         command ssh "$@"
       } always {
         cd .
       }
     };# ssh()
How can I avoid writing all that code again and again?

Thanks in advance

You could build a function factory with eval, but in this case there is an
even easier possibility:

function ssh telnet su bash zsh tcsh {
	set_title "$0 $@"
	{
		command $0 "$@"
	} always {
		cd .
	}
}

This defines a function for ssh, telnet etc., $0 always evaluates to the name
by which the function was called.

Try precmd() function.  man zshall -> SPECIAL FUNCTIONS -> Hook
