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.

NAME

       Tree::Simple::Visitor::VariableDepthClone - A Visitor for cloning parts of Tree::Simple hierarchy

SYNOPSIS

	 use Tree::Simple::Visitor::VariableDepthClone;

	 # create an visitor
	 my $visitor = Tree::Simple::Visitor::VariableDepthClone->new();

	 $visitor->setCloneDepth(3);

	 # pass our visitor to the tree
	 $tree->accept($visitor);

	 my $partial_tree = $visitor->getClone();

DESCRIPTION

       This visitor will clone

METHODS

       new There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter" method to customize
	   its behavior.

       includeTrunk ($boolean)
	   Based upon the value of $boolean, this will tell the visitor to include the trunk of the tree in the traversal as well. This basically
	   means it will clone the root node as well.

       setCloneDepth ($number)
       setNodeFilter ($filter_function)
	   This method accepts a CODE reference as its $filter_function argument and throws an exception if it is not a code reference. This code
	   reference is used to filter the tree nodes as they are cloned.

       visit ($tree)
	   This is the method that is used by Tree::Simple's "accept" method. It can also be used on its own, it requires the $tree argument to be
	   a Tree::Simple object (or derived from a Tree::Simple object), and will throw and exception otherwise.

       getClone
	   This method returns the cloned partial tree.

BUGS

       None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.

CODE COVERAGE

       See the CODE COVERAGE section in Tree::Simple::VisitorFactory for more inforamtion.

SEE ALSO

       These Visitor classes are all subclasses of Tree::Simple::Visitor, which can be found in the Tree::Simple module, you should refer to that
       module for more information.
