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_CPAN 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.
