Re: Accessing variables in a runtime-loaded module

What's the error message that you get? That problematic line works for me.

#!/usr/bin/perl
use lib "/Users/brian/Desktop";

require "Foo.pm";

$module = 'Foo';

print $module->description, "\n";

where Foo.pm is

package Foo;

sub description { "Hello there!" }

1;

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;` [download] So Foo::description is a scalar, not a subroutine. And when trying to access the variable content perl says that it's undefined.	[reply] [d/l]

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]
