NAME

Acme::ReturnValue - report interesting module return values

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'.

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!

in_INC

    $arv->in_INC;

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

in_dir

    $arv->in_dir( $some_dir );

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

in_file

    $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.

interesting

Returns an ARRAYREF containing 'interesting' modules.

boring

Returns an ARRAYREF containing 'boring' modules.

failed

Returns an ARRAYREF containing unparsable modules.

BUGS

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