Re^2: Accessing variables in a runtime-loaded module

Ah, but I'm trying to use this as plugin:

package Foo;
use vars( qw (@ISA @EXPORT @EXPORT_OK %EXPORT_TAGS $VERSION) );

require Exporter;

@ISA = qw( Exporter );
@EXPORT = qw( $description );
@EXPORT_OK = ();
%EXPORT_TAGS = ();
$VERSION = "0.1";

my $description="Plugin I am!"

1;

So Foo::description is a scalar, not a subroutine. And when trying to access the variable content perl says that it's undefined.

lexical variables can never be accessed from outside your package/file. You need a package global variable, eg. `our $description` to be able to access it. See perlmod for more on packages and modules. Paul	[reply] [d/l]

You don't need a package variable: you need an acccessor method. Global variables suck. :) `my $description = 'foo'; sub description { $description }` [download] -- brian d foy <brian@stonehenge.com>	[reply] [d/l]
