6 countperl - count lines, packages, subs and complexity of Perl files.
7
9 countperl FILE_OR_DIRECTORY [FILE_OR_DIRECTORY ...] [--html] [--help]
10 [--method-modifiers=a,b,c]
11
13 At least one file or directory path must be supplied.
14
16 --help
17 Prints documentation to STDERR.
18 --html
20 Produces HTML output instead of the plain-text default.
21 --json
23 Produces JSON output instead of the plain-text default.
24 --method-modifiers=a,b,c
26 A comma-separated list of method modifiers to be recognised, see
27 Moose::Manual::MethodModifiers for details. If unspecified, the
28 default list is before,after,around.
29
31 N/A. Currently no support for any configuration files.
32
34 Exits zero on success, non-zero on failure.
35
37 countperl uses Perl::Metrics::Simple to examines the named files and
38 recursivesly searches named directories for Perl files.
39 Perl files are identified by Perl::Metrics::Simple->is_perl_file.
41 Basically if the file ends in ".pl", ".pm", or ".t" or has what appears
42 to be a perl shebang line.
43 countperl produces a report on STDOUT of counts of total lines,
45 packages, subroutines/methods, the minimum, maximum, mean, standard
46 deviation, and median size and mccabe_complexity (cyclomatic
47 complexity) of subroutines and the 'main' portion of each file
48 (everything not in a subroutine.)
49 Output Format
51 Line counts do not include comments nor pod.
