NAME

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

SYNOPSIS

  use Perl::PrereqScanner::NotQuiteLite;
  my $scanner = Perl::PrereqScanner::NotQuiteLite->new(
    parsers => [qw/:installed -UniversalVersion/],
    suggests => 1,
  );
  my $context = $scanner->scan_file('path/to/file');
  my $requirements = $context->requires;
  my $recommends = $context->recommends;
  my $suggestions  = $context->suggests; # requirements in evals
  my $noes = $context->noes;

BACKWARD INCOMPATIBLILITY

As of 0.49_01, the internal of this module was completely rewritten. I'm supposing there's no one who has written their own parsers for the previous version, but if this assumption was wrong, let me know.

DESCRIPTION

Perl::PrereqScanner::NotQuiteLite is yet another prerequisites scanner. It passes almost all the scanning tests for Perl::PrereqScanner and Module::ExtractUse (ie. except for a few dubious ones), and runs slightly faster than PPI-based Perl::PrereqScanner. However, it doesn't run as fast as Perl::PrereqScanner::Lite (which uses an XS lexer).

Perl::PrereqScanner::NotQuiteLite also recognizes eval. Prerequisites in eval are not considered as requirements, but you can collect them as suggestions.

Conditional requirements or requirements loaded in a block are treated as recommends. Noed modules are stored separately (since 0.94). You may or may not need to merge them into requires.

METHODS

new

creates a scanner object. Options are:

parsers

By default, Perl::PrereqScanner::NotQuiteLite only recognizes modules loaded directly by use, require, no statements, plus modules loaded by a few common modules such as base, parent, if (that are in the Perl core), and by two keywords exported by Moose family (extends and with).

If you need more, you can pass extra parser names to the scanner, or :installed, which loads and registers all the installed parsers under Perl::PrereqScanner::NotQuiteLite::Parser namespace.

You can also pass a project-specific parser (that lies outside the Perl::PrereqScanner::NotQuiteLite::Parser namespace) by prepending + to the name.

  use Perl::PrereqScanner::NotQuiteLite;
  my $scanner = Perl::PrereqScanner::NotQuiteLite->new(
    parsers => [qw/+PrereqParser::For::MyProject/],
  );

If you don't want to load a specific parser for some reason, prepend - to the parser name.

suggests

Perl::PrereqScanner::NotQuiteLite ignores use-like statements in eval by default. If you set this option to true, Perl::PrereqScanner::NotQuiteLite also parses statements in eval, and records requirements as suggestions.

scan_file

takes a path to a file and returns a ::Context object.

scan_string

takes a string, scans and returns a ::Context object.
