NAME

Acme::ReturnValue - report interesting return values

VERSION

version 1.001

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!

in_CPAN

Analyse CPAN. Needs a local CPAN mirror

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

BUGS

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