NAME

Acme::ReturnValue - report interesting return values

VERSION

version 1.000

SYNOPSIS

use Acme::ReturnValue;
my $rvs = Acme::ReturnValue->new;
$rvs->in_INC;
foreach (@{$rvs->interesting}) {
    say $_->{package} . ' returns ' . $_->{value};
}

DESCRIPTION

Acme::ReturnValue will list 'interesting' return values of modules. 'Interesting' means something other than '1'.

See http://returnvalues.useperl.at for the results of running Acme::ReturnValue on the whole CPAN.

METHODS

run

run from the commandline (via acme_returnvalue.pl

waste_some_cycles

my $data = $arv->waste_some_cycles( '/some/module.pm' );

waste_some_cycles parses the passed in file using PPI. It tries to get the last statement and extract it's value.

waste_some_cycles returns a hash with following keys

  • file

    The file

  • package

    The package defintion (the first one encountered in the file

  • value

    The return value of that file

waste_some_cycles will also put this data structure into interesting or boring.

You might want to pack calls to waste_some_cycles into an eval because PPI dies on parse errors.

_is_code

Stolen directly from Perl::Critic::Policy::Modules::RequireEndWithOne as suggested by Chris Dolan.

Thanks!

Probably many, because I'm not sure I master PPI yet.
