NAME

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

SYNOPSIS

         use Perl::Metrics::Simple;
         my $analyzer = Perl::Metrics::Simple->new;
         my $analysis = $analyzer->analyze_files(@paths, @refs_to_file_contents);
         $file_count    = $analysis->file_count;
         $package_count = $analysis->package_count;
         $sub_count     = $analysis->sub_count;
         $lines         = $analysis->lines;
         $main_stats    = $analysis->main_stats;
         $file_stats    = $analysis->file_stats;

VERSION

       This is VERSION 0.12

DESCRIPTION

       Perl::Metrics::Simple provides just enough methods to run static analysis of one or many
       Perl files and obtain a few metrics: packages, subroutines, lines of code, and an
       approximation of cyclomatic (mccabe) complexity for the subroutines and the "main" portion
       of the code.

       Perl::Metrics::Simple is far simpler than Perl::Metrics.

       Installs a script called countperl.

USAGE

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

CLASS METHODS

   new
       Takes no arguments and returns a new Perl::Metrics::Simple object.

   is_perl_file
       Takes a path and returns true if the target is a Perl file.

OBJECT METHODS

   analyze_files( @paths, @refs_to_file_contents )
       Takes an array of files and or directory paths, and/or SCALAR refs to file contents and
       returns an Perl::Metrics::Simple::Analysis object.

   find_files( @directories_and_files )
       Uses list_perl_files to find all the readable Perl files and returns a reference to a
       (possibly empty) list of paths.

   list_perl_files
       Takes a list of one or more paths and returns an alphabetically sorted list of only the
       perl files.  Uses is_perl_file so may throw an exception if a file is unreadable.

   is_perl_file($path)
       Takes a path to a file and returns true if the file appears to be a Perl file, otherwise
       returns false.

       If the file name does not match any of @Perl::Metrics::Simple::PERL_FILE_SUFFIXES then the
       file is opened for reading and the first line examined for a a Perl 'shebang' line. An
       exception is thrown if the file cannot be opened in this case.

   should_be_skipped($path)
       Returns true if the path should be skipped when looking for Perl files.  Currently skips
       .svn, CVS, and _darcs directories.
