Re: C-Style Struct?

in reply to C-Style Struct?

I'm not really familiar with C. But does this work like a struct?

sub struct {
  my ($name, %args) = @_;
  localscope: {
    # we want to mangle the symbol table
    # so set 'no strict refs'
    no strict 'refs';
    foreach my $a (keys %args) {
      *{"${name}::${a}"} = sub {
        my ($class, $val) = @_;
        # val means it needs updating
        if ($val) {
          nowarning: {
            no warnings 'redefine';
            *{"${name}::${a}"} = sub {
              $val;
            };
          } # end nowarning
          return $val;
        }
        return $args{$a}
      };
    }
  } # end localscope
}

# Create a new struct
struct 'Player' => (
  count_var => 0,
  name => 'Zork',
  list_of_stuff => ['a', 'b']
);

print Player->name;
# you can update a value in this "struct", like so
Player->name('Zippy');

Thinking about it, Class::Struct as mentioned in the first reply is probably a nicer option. Seems to do the same thing, but better. And it looks like it's included in perl5.16 - nice!
