$0 in function

$0 in function

[Joakim Ryden]

I have a simple catch-all error function like so:

function print_error() {

        echo "$0: an error ocurred"
        echo -e "check buildlog: $BUILD_LOG for more information\n"
        exit 1
}

In bash this prints on error:
./build_apache: an error ocurred.
check buildlog: /home/jo/www/build.log for more information
In zsh it prints:
print_error: an error ocurred. 
check buildlog: /home/jo/www/build.log for more information

Is there an option I need to (un)set to emulate the bash behaviour in
this instance?

Thanks!
Jo

$ setopt function_argzero.

You're looking to modify the behaviour of a parameter.  So look at the
docs for that parameter ...

$ man zshparam
[...]
       0 <S>  The  name used to invoke the current shell.  If the
              FUNCTION_ARGZERO option is set, this  is  set  tem­
              porarily within a shell function to the name of the
              function, and within a sourced script to  the  name
              of the script.

Hmm, thanks. Is function_argzero supposed to show up in the setopt list?

% setopt
interactive
monitor
shinstdin
zle
% setopt function_argzero
% setopt
interactive
monitor
shinstdin
zle

(and the function still prints the same thing as before)

	Unless you have the option kshoptionprint set, setopt
only shows options that have changed from their default value.  The
default for function_argzero is on, so you would normally only see it
in setopt's output as nofunctionargzero, when you disable it.
	What do you get after a
$ setopt nofunctionargzero
	?

Thanks Sweth - nevermind, it helps to have your terminal windows
straight at 1:30 in the am - it's all good. :)
