NAME

       Perl::PrereqScanner - a tool to scan your Perl code for its prerequisites

VERSION

       version 1.023

SYNOPSIS

         use Perl::PrereqScanner;
         my $scanner = Perl::PrereqScanner->new;
         my $prereqs = $scanner->scan_ppi_document( $ppi_doc );
         my $prereqs = $scanner->scan_file( $file_path );
         my $prereqs = $scanner->scan_string( $perl_code );
         my $prereqs = $scanner->scan_module( $module_name );

DESCRIPTION

       The scanner will extract loosely your distribution prerequisites from your files.

       The extraction may not be perfect but tries to do its best. It will currently find the
       following prereqs:

       ·   plain lines beginning with "use" or "require" in your perl modules and scripts,
           including minimum perl version

       ·   regular inheritance declared with the "base" and "parent" pragmata

       ·   Moose inheritance declared with the "extends" keyword

       ·   Moose roles included with the "with" keyword

       ·   OO namespace aliasing using the "aliased" module

   Scanner Plugins
       Perl::PrereqScanner works by running a series of scanners over a PPI::Document
       representing the code to scan.  By default the "Perl5", "Moose", "TestMore", "POE", and
       "Aliased" scanners are run.  You can supply your own scanners when constructing your
       PrereqScanner:

         # Us only the Perl5 scanner:
         my $scanner = Perl::PrereqScanner->new({ scanners => [ qw(Perl5) ] });

         # Use any stock scanners, plus Example:
         my $scanner = Perl::PrereqScanner->new({ extra_scanners => [ qw(Example) ] });

METHODS

   scan_string
         my $prereqs = $scanner->scan_string( $perl_code );

       Given a string containing Perl source code, this method returns a CPAN::Meta::Requirements
       object describing the modules it requires.

       This method will throw an exception if PPI fails to parse the code.

       Warning!  It isn't entirely clear whether PPI prefers to receive strings as octet strings
       or character strings.  For now, my advice is to pass octet strings.

   scan_file
         my $prereqs = $scanner->scan_file( $path );

       Given a file path to a Perl document, this method returns a CPAN::Meta::Requirements
       object describing the modules it requires.

       This method will throw an exception if PPI fails to parse the code.

   scan_ppi_document
         my $prereqs = $scanner->scan_ppi_document( $ppi_doc );

       Given a PPI::Document, this method returns a CPAN::Meta::Requirements object describing
       the modules it requires.

   scan_module
         my $prereqs = $scanner->scan_module( $module_name );

       Given the name of a module, eg 'PPI::Document', this method returns a
       CPAN::Meta::Requirements object describing the modules it requires.
