NAME

countperl - count lines, packages, subs and complexity of Perl files.

USAGE

countperl FILE_OR_DIRECTORY [FILE_OR_DIRECTORY ...] [--html] [--help] [--method-modifiers=a,b,c]

REQUIRED ARGUMENTS

At least one file or directory path must be supplied.

OPTIONS

--help

Prints documentation to STDERR.

--html

Produces HTML output instead of the plain-text default.

--json

Produces JSON output instead of the plain-text default.

--method-modifiers=a,b,c

A comma-separated list of method modifiers to be recognised, see Moose::Manual::MethodModifiers for details. If unspecified, the default list is before,after,around.

CONFIGURATION

N/A. Currently no support for any configuration files.

EXIT STATUS

Exits zero on success, non-zero on failure.

DESCRIPTION

countperl uses Perl::Metrics::Simple to examines the named files and recursivesly searches named directories for Perl files.

Perl files are identified by Perl::Metrics::Simple->is_perl_file. Basically if the file ends in ".pl", ".pm", or ".t" or has what appears to be a perl shebang line.

countperl produces a report on STDOUT of counts of total lines, packages, subroutines/methods, the minimum, maximum, mean, standard deviation, and median size and mccabe_complexity (cyclomatic complexity) of subroutines and the 'main' portion of each file (everything not in a subroutine.)
