Acme::ReturnValue - report interesting module return values

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

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

run from the commandline (via acme_returnvalue.pl

    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.

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

Thanks!

    $arv->in_INC;

Collect return values from all *.pm files in @INC.

    $arv->in_dir( $some_dir );

Collect return values from all *.pm files in $dir.

    $arv->in_file( $some_file );

Collect return value from the passed in file.

If waste_some_cycles failed, puts information on the failing file into failed.

Returns an ARRAYREF containing 'interesting' modules.

Returns an ARRAYREF containing 'boring' modules.

Returns an ARRAYREF containing unparsable modules.

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