NAME

6       Perl::Metrics::Simple - Count packages, subs, lines, etc. of many
7       files.

SYNOPSIS

10         use Perl::Metrics::Simple;
11         my $analyzer = Perl::Metrics::Simple->new;
12         my $analysis = $analyzer->analyze_files(@paths, @refs_to_file_contents);
13         $file_count    = $analysis->file_count;
14         $package_count = $analysis->package_count;
15         $sub_count     = $analysis->sub_count;
16         $lines         = $analysis->lines;
17         $main_stats    = $analysis->main_stats;
18         $file_stats    = $analysis->file_stats;

DESCRIPTION

24       Perl::Metrics::Simple provides just enough methods to run static
25       analysis of one or many Perl files and obtain a few metrics: packages,
26       subroutines, lines of code, and an approximation of cyclomatic (mccabe)
27       complexity for the subroutines and the "main" portion of the code.
28
29       Perl::Metrics::Simple is far simpler than Perl::Metrics.
30
31       Installs a script called countperl.
32

USAGE

34       See the countperl script (included with this distribution) for a simple
35       example of usage.
36

CLASS METHODS

38   new
39       Takes no arguments and returns a new Perl::Metrics::Simple object.
40
41   is_perl_file
42       Takes a path and returns true if the target is a Perl file.
43

OBJECT METHODS

45   analyze_files( @paths, @refs_to_file_contents )
46       Takes an array of files and or directory paths, and/or SCALAR refs to
47       file contents and returns an Perl::Metrics::Simple::Analysis object.
48
49   find_files( @directories_and_files )
50       Uses list_perl_files to find all the readable Perl files and returns a
51       reference to a (possibly empty) list of paths.
52
53   list_perl_files
54       Takes a list of one or more paths and returns an alphabetically sorted
55       list of only the perl files.  Uses is_perl_file so may throw an
56       exception if a file is unreadable.
57
58   is_perl_file($path)
59       Takes a path to a file and returns true if the file appears to be a
60       Perl file, otherwise returns false.
61
62       If the file name does not match any of
63       @Perl::Metrics::Simple::PERL_FILE_SUFFIXES then the file is opened for
64       reading and the first line examined for a a Perl 'shebang' line. An
65       exception is thrown if the file cannot be opened in this case.
66
67   should_be_skipped($path)
68       Returns true if the path should be skipped when looking for Perl files.
69       Currently skips  .svn, CVS, and _darcs directories.
