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.
