NAME ^

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

USAGE ^

countperl FILE_OR_DIRECTORY [FILE_OR_DIRECTORY ....] [--html] [--help]

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.

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
    5       is_perl_file    lib/Perl/Metrics/Simple.pm      11
    5       _has_perl_shebang       lib/Perl/Metrics/Simple.pm      13
    5       _init   lib/Perl/Metrics/Simple/Analysis/File.pm        30

    4       is_ref  lib/Perl/Metrics/Simple/Analysis.pm     8

With --html switch output format is HTML.
