Perl::Critic::Pulp::Utils - shared helper code for the Pulp perlcritic add-on
use Perl::Critic::Pulp::Utils;
This is a bit of a grab bag, but works as far as it goes.
$pkgelem = Perl::Critic::Pulp::Utils::elem_package ($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.
$elem
PPI::Element
PPI::Statement::Package
undef
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").
BEGIN
PPI::Statement::Scheduled
$bool = Perl::Critic::Pulp::Utils::elem_is_comma_operator ($elem)
Return true if $elem (a PPI::Element) is a comma operator (PPI::Token::Operator), either "," or "=>'.
PPI::Token::Operator
Perl::Critic::Pulp::Utils::parameter_parse_version ($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.
parser
supported_parameters
{ 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.
$str
version.pm
$self->__set_parameter_value
version
$self->throw_parameter_value_exception
Nothing is exported by default, but the functions can be requested in usual Exporter style,
Exporter
use Perl::Critic::Pulp::Utils 'elem_in_BEGIN'; if (elem_in_BEGIN($elem)) { # ... }
There's no :all tag since this module is meant as a grab-bag of functions and importing as-yet unknown things would be asking for name clashes.
