Moo and Spreadsheet::ParseExcel

karlgoethebier has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks, this code...

package MyParseExcel;
use Spreadsheet::ParseExcel;
use Moo::Role;
use MooX::Types::MooseLike::Base qw(InstanceOf Str);
1;
[download]

...leads to:

Use of uninitialized value $roles[0] in sort at
C:/Perl/site/lib/Role/Tiny.pm line 199.
Compilation failed in require at C:\path\run.pl line 6.
[download]

But this one...

package MyParseExcel;
# use Spreadsheet::ParseExcel;
use Moo::Role;
use MooX::Types::MooseLike::Base qw(InstanceOf Str);
1;
[download]

...works. In Role::Tiny i see...

sub _composite_info_for {
 my ($me, @roles) = @_;
 $COMPOSITE_INFO{join('|', sort @roles)} ||= do { #  <-- 199
   _load_module($_) for @roles;
   my %methods;
   foreach my $role (@roles) {
     my $this_methods = $me->_concrete_methods_of($role);
     $methods{$_}{$this_methods->{$_}} = $role for keys %$this_methods
+;
   }
   delete $methods{$_} for grep keys(%{$methods{$_}}) == 1, keys %meth
+ods;
   +{ conflicts => \%methods }
 };
}
[download]

Perhaps i found another module that can't with Moo? This was my doubt using Moo: Long time used modules don't work as expected. Hope i don't miss something.

Thank you for your patience and help.

Regards, Karl

I'm not able to reproduce that error message. Are you using the latest versions of all three modules? You could try re-ordering the `use` statements, perhaps putting Moo::Role first. `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply] [d/l]

`Spreadsheet::ParseExcel 0.59 Moo 1.000005 MooX::Types::MooseLike::Base 0.16` [download] All up to date. Re-ordering the use statements brought no success. I've tried this already. I don't have any idea for the moment. Regards, Karl ŤThe Crux of the Biscuit is the Apostropheť	[reply] [d/l]

What's in `run.pl`?? `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply] [d/l]

The only plan i have at the moment is: Not using roles and rewrite the stuff. Regards, Karl ŤThe Crux of the Biscuit is the Apostropheť	[reply]
