NAME Module::Build::Convert - Makefile.PL to Build.PL converter SYNOPSIS use Module::Build::Convert; my %params = (Path => '/path/to/perl/distribution(s)', Verbose => 2, Use_Native_Order => 1, Len_Indent => 4); my $make = Module::Build::Convert->new(%params); $make->convert; DESCRIPTION "ExtUtils::MakeMaker" has been a de-facto standard for the common distribution of Perl modules; "Module::Build" is expected to supersede "ExtUtils::MakeMaker" in some time (part of the Perl core as of 5.10?) The transition takes place slowly, as the converting process manually achieved is yet an uncommon practice. The Module::Build::Convert Makefile.PL parser is intended to ease the transition process. CONSTRUCTOR new Options: Path Path to a Perl distribution. May point to a single distribution directory or to one containing more than one distribution. Default: '' Makefile_PL Filename of the Makefile script. Default: Makefile.PL Build_PL Filename of the Build script. Default: Build.PL MANIFEST Filename of the MANIFEST file. Default: MANIFEST RC Filename of the RC file. Default: .make2buildrc Dont_Overwrite_Auto If a Build.PL already exists, output a notification and ask whether it should be overwritten. Default: 1 Create_RC Create a RC file in the homedir of the current user. Default: 0 Exec_Makefile Execute the Makefile.PL via 'do Makefile.PL'. Default: 0 Verbose Verbose mode. If set to 1, overridden defaults and skipped arguments are printed while converting; if set to 2, output of "Verbose = 1" and created Build script will be printed. May be set via the make2build switches "-v" (mode 1) and "-vv" (mode 2). Default: 0 Debug Rudimentary debug facility for examining the parsing process. Default: 0 Use_Native_Order Native sorting order. If set to 1, the native sorting order of the Makefile arguments will be tried to preserve; it's equal to using the make2build switch "-n". Default: 0 Len_Indent Indentation (character width). May be set via the make2build switch "-l". Default: 3 DD_Indent "Data::Dumper" indendation mode. Mode 0 will be disregarded in favor of 2. Default: 2 DD_Sortkeys "Data::Dumper" sort keys. Default: 1 METHODS convert Parses the Makefile.PL's "WriteMakefile()" arguments and converts them to "Module::Build" equivalents; subsequently the according Build.PL is created. Takes no arguments. DATA SECTION Argument conversion "ExtUtils::MakeMaker" arguments followed by their "Module::Build" equivalents. Converted data structures preserve their native structure, that is, "HASH" -> "HASH", etc. NAME module_name DISTNAME dist_name ABSTRACT dist_abstract AUTHOR dist_author VERSION dist_version VERSION_FROM dist_version_from PREREQ_PM requires PL_FILES PL_files PM pm_files MAN1PODS pod_files XS xs_files INC include_dirs INSTALLDIRS installdirs DESTDIR destdir CCFLAGS extra_compiler_flags EXTRA_META meta_add SIGN sign LICENSE license clean.FILES @add_to_cleanup Default arguments "Module::Build" default arguments may be specified as key/value pairs.

In order to convert arguments, a typeglob from "WriteMakefile()" to an internal sub will be set; subsequently Makefile.PL will be executed and the arguments are then accessible to the internal sub. Data::Dumper Converted "ExtUtils::MakeMaker" arguments will be dumped by "Data::Dumper's" "Dump()" and are then furtherly processed. BUGS & CAVEATS "Module::Build::Convert" should be considered experimental as the parsing of the Makefile.PL doesn't necessarily return valid arguments, especially for Makefiles with bad or even worse, missing intendation. The parsing process may sometimes hang with or without warnings in such cases. Debugging by using the appropriate option/switch (see CONSTRUCTOR/new) may reveal the root cause.
