6 Perl::Critic::Utils::McCabe - Functions that calculate the McCabe score
7 of source code.
8
10 Provides approximations of McCabe scores. The McCabe score of a set of
11 code describes the number of possible paths through it. The functions
12 here approximate the McCabe score by summing the number of conditional
13 statements and operators within a set of code. See
14 <http://en.wikipedia.org/wiki/Cyclomatic_complexity> for some
15 discussion about the McCabe number and other complexity metrics.

19 will go through a deprecation cycle.

22 "calculate_mccabe_of_sub( $sub )"
23 Calculates an approximation of the McCabe number of the code in a
24 PPI::Statement::Sub.
25
26 "calculate_mccabe_of_main( $doc )"
27 Calculates an approximation of the McCabe number of all the code in
28 a PPI::Statement::Document that is not contained in a subroutine.
