in reply to Export all subs from a module

All you need to do is to build your @EXPORT array dynamically after defining all of your functions.

use strict;

package MyModule;
use vars qw(@ISA @EXPORT);

require Exporter;
@ISA = qw(Exporter);

sub test { print "In test\n" };

sub test_again { print "In test_again\n" };

sub last_test{ print "In last_test\n" };

while (my ($name, $glob) = each %MyModule::) {
  push @EXPORT, $name if defined *$glob{CODE};
}

1;

      That's nice, but it potentially exports too much - not just the subs, but everything in stash.

      To do this in a way that doesn't export package vars as well (which I believe was davorg's objection), perhaps this would work:

      @EXPORT_OK = grep {defined *{$MyPackage::{$_}}{CODE} }
                  keys %MyPackage::;

      And unless I'm very much mistaken, that line could just as well be at the top of your package as at the bottom: unless you're doing fancy run-time redefinition of subs, they should all be defined by the time the first line of non-begin-block code gets evaluated.

        Thanks everyone for your help - I'll go with this method.

        Looks easy to export nearly-all the subs, like maybe all of them except the ones which start with underscores, which could be handy for the future.

        Cheers!
