Module::MakefilePL::Parse 0.12

Module::MakefilePL::Parse is a Perl module to parse required modules from Makefile.PL.

SYNOPSIS

use Module::MakefilePL::Parse;

open $fh, Makefile.PL;

$parser = Module::MakefilePL::Parse->new( join("", <$fh>) );

$info = $parser->required;

The purpose of this module is to determine the required modules for older CPAN distributions which do not have META.yml files but use Makefile.PL and ExtUtils::MakeMaker or Module::Install.

Presumably newer style Makefile.PL files which use Module::Install or Module::Build already have META.yml files in their distributions.

Methods

new

$parser = new Modile::MakefilePL::Parse( $script );

Parses a Makefile.PL script and returns an object. Returns undef if there is a problem.

required

$info = $parser->required;

Returns a hash reference containing the prerequisite modules. This is either the the PREREQ_PM key, or a combination of prerequisites specified in requires and build_requires calls in the Makefile.PL script (depending on the "install_type").

install_type

$module = $parser->install_type;

Returns the module used for installation.

CAVEATS

This module does evaluate a portion of the code, so there is a security issue. However, it only evaluates the definition of the PREREQ_PM key in calls to WriteMakefile, which should be more difficult to embed malware in.
Do not run this module on untrusted scripts.
