NAME

Perl::Critic::Pulp::Utils - shared helper code for the Pulp perlcritic add-on

SYNOPSIS

 use Perl::Critic::Pulp::Utils;

DESCRIPTION

This is a bit of a grab bag, but works as far as it goes.

FUNCTIONS

Element Functions

$pkgelem = Perl::Critic::Pulp::Utils::elem_package ($elem)

$elem is a PPI::Element. Return the PPI::Statement::Package containing $elem, or undef if $elem is not in the scope of any package statement.

The search upwards begins with the element preceding $elem, so if $elem itself is a PPI::Statement::Package then that's not the one returned, instead its containing package.

$bool = Perl::Critic::Pulp::Utils::elem_in_BEGIN ($elem)

Return true if $elem (a PPI::Element) is within a BEGIN block (ie. a PPI::Statement::Scheduled of type "BEGIN").

Policy Parameter Functions

Perl::Critic::Pulp::Utils::parameter_parse_version ($self, $parameter, $str)

This is designed for use as the parser field of a policy's supported_parameters entry for a parameter which is a version number.

    { name        => 'above_version',
      description => 'Check only above this version of Perl.',
      behavior    => 'string',
      parser      => \&Perl::Critic::Pulp::Utils::parameter_parse_version,
    }    

$str is parsed with the version.pm module. If valid then the parameter is set with $self->__set_parameter_value to the resulting version object (so for example field $self->{'_above_version'}). If invalid then an exception is thrown per $self->throw_parameter_value_exception.
