NAME

Perl::Metrics::Plugin::Core - The Core Perl Metrics Package

DESCRIPTION

This class provides a set of core metrics for Perl documents, based on very simple code using only the core PPI package.

As with all Perl::Metrics::Plugin packages, all metrics can be referenced with the global identifier Perl::Metrics::Plugin::Core::metric.

Metrics are listed as "datatype name".

The tokens metric represents the total number of PPI::Token objects contained in the document.

For example, the following one-line document would have a tokens metric of 5 (assuming a single trailing newline)

print "Hello World!\n";

The significant_tokens metric represents the total number of significant tokens contained in the document.

This filters out things like whitespace and comments, and refers (more or less) to only the parts of the document that actually do something.

For more information on significance, see "significant" in PPI::Element.
