Perl::Metrics::Simple(3pm) User Contributed Perl Documentation Perl::Metrics::Simple(3pm)
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.
