Perl::Metrics2::Plugin::Core - The Core Perl Metrics Package
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
Metrics are listed as "datatype name".
bytes metric represents the number of bytes in the file.
lines metric represents the number of raw lines in the file.
sloc metric represents Source Lines of Code.
raw lines minus __END__ content,
comments and blank lines.
tokens metric represents the total number of PPI::Token objects contained in the document.
the following one-line document would have a
tokens metric of 5 (assuming a single trailing newline)
print "Hello World!\n";
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.
