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.)

   Output Format
       Line counts do not include comments nor pod.

       The current output format is human-readable text:

           Perl files found:                3

           Counts
           ------
           total code lines:       856
           lines of non-sub code:  450
           packages found:           3
           subs/methods:            42

           Subroutine/Method Size
           ----------------------
           min:                  3 lines
           max:                  32 lines
           mean:                 9.67 lines
           std. deviation:       7.03
           median:               7.50

           McCabe Complexity
           -----------------
           Code not in any subroutine::
           min:                  1
           max                   1
           mean:                 1.00
           std. deviation:       0.00
           median:               1.00

           Subroutines/Methods:
           min:                  1
           max:                  5
           avg:                  1.00
           std. deviation:       1.36
           median:               1.00

           Tab-delimited list of subroutines, with most complex at top
           -----------------------------------------------------------
           complexity      sub     path    size
