Perl::Critic::Pulp::Utils

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 ").

"$bool = Perl::Critic::Pulp::Utils::elem_is_comma_operator ($elem)"

Return true if $elem (a "PPI::Element") is a comma operator ("PPI::Token::Operator"), either "," or "=>’.

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".

EXPORTS

Nothing is exported by default, but the functions can be requested in usual "Exporter" style,

    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.
