Sommaire

NAME

Perl::Critic::Utils::McCabe - Functions that calculate the McCabe score of source code.

DESCRIPTION

Provides approximations of McCabe scores. The McCabe score of a set of code describes the number of possible paths through it. The functions here approximate the McCabe score by summing the number of conditional statements and operators within a set of code. See <http://www.sei.cmu.edu/str/descriptions/cyclomatic_body.html> for some discussion about the McCabe number and other complexity metrics.

INTERFACE SUPPORT

This is considered to be a public module. Any changes to its interface will go through a deprecation cycle.

calculate_mccabe_of_sub( $sub )
Calculates an approximation of the McCabe number of the code in a PPI::Statement::Sub.
calculate_mccabe_of_main( $doc )
