NAME

Perl::PrereqScanner::Lite - Lightweight Prereqs Scanner for Perl

SYNOPSIS

use Perl::PrereqScanner::Lite;

my $scanner = Perl::PrereqScanner::Lite->new;
$scanner->add_extra_scanner('Moose');
my $modules = $scanner->scan_file('path/to/file');

DESCRIPTION

Perl::PrereqScanner::Lite is the lightweight prereqs scanner for perl. This scanner uses Compiler::Lexer as tokenizer, therefore processing speed is really fast.

METHODS

• new

  Create scanner instance.

• scan_file($file_path)

  Scan and figure out prereqs by file path.

• scan_string($string)

  Scan and figure out prereqs by source code string written in perl.

  e.g.

    open my $fh, '<', __FILE__;
    my $string = do { local $/; <$fh> };
    my $modules = $scanner->scan_string($string);
  

• scan_module($module_name)

  Scan and figure out prereqs by module name.

  e.g.

    my $modules = $scanner->scan_module('Perl::PrereqScanner::Lite');
  

• scan_tokens($tokens)

  Scan and figure out prereqs by tokens of Compiler::Lexer.

  e.g.

    open my $fh, '<', __FILE__;
    my $string = do { local $/; <$fh> };
    my $tokens = Compiler::Lexer->new->tokenize($string);
    my $modules = $scanner->scan_tokens($tokens);
  

• add_extra_scanner($scanner_name)

  Add extra scanner to scan and figure out prereqs. This module loads extra scanner such as Perl::PrereqScanner::Lite::Scanner::$scanner_name if specifying scanner name through this method.

  Now this module supports extra scanner for Moose families extends notation. Please see also Perl::PrereqScanner::Lite::Scanner::Moose.
