zparseopts inside functions

zparseopts inside functions

[Meino Christian Cramer]

 Hi,

  I wrote a little testscript:

    #! /bin/zsh
    
    zparseopts s:=svar t:=tvar u:=uvar
    echo $svar
    echo $tvar
    echo $uvar

 which works nice.

 But if I write this instead:

    #! /bin/zsh
    
    function takeargs
    {   
        zparseopts s:=svar t:=tvar u:=uvar
        echo $svar
        echo $tvar
        echo $uvar
    }

    takeargs


 nothing works anymore (the echo put only "\n"'s on my screen...).

 I am sure I missed a very basic simple thing...but unfortunately I
 seem to be "blinded by the screen"...

 Thank you very much in advace!
 Have a nice weekend!

Change the last line to

    takeargs "$@"

Hi Michael,

 thanks for your reply!

 Yes, it works! :)

 ...but I thought, $ARGV and friends would be global......

 Have a nice weekend!
