Re: Making variables visible between calls.

[jeffa]

How about just this?

my $function = sub {
    my $var = 'xpto'; print ">> $var <<\n"
};

$function->();

That doesn't help. I need to let the user define his own function, and give him the possibility to access some pre-defined variables in case he wish to.

My only possibility at the moment is to force the user defined function to receive a set of predefined parameters. But that will mess up some things later...

But thanks, anyway ;)

It sounds like you realy want to pass it a hash. Then just preload the hash with values that it should have access to.

  my $function = sub {my $v = shift; print ">> $v->{var} <<\n" };
  my $params = {var => 'exto'};
  $function->($params);
