NAME

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

VERSION

version 0.100520

SYNOPSIS

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

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

It will trim the following pragamata: strict, warnings, and lib. base is trimmed unless a specific version is required. parent is kept, since it's only recently become a core library.

METHODS

scan_string

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

Return a list of prereqs with their minimum version (0 if no minimum specified) given a string of Perl code.

scan_file

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

Return a list of prereqs with their minimum version (0 if no minimum specified) given a path to a Perl file.

scan_ppi_document

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

Return a list of prereqs with their minimum version (0 if no minimum specified) given a PPI::Document.
