NAME

       Dist::Zilla::Plugin::MakeMaker::Custom - Allow a dist to have a custom Makefile.PL

VERSION

       This document describes version 4.08 of Dist::Zilla::Plugin::MakeMaker::Custom, released June 4, 2012 as part of Dist-Zilla-Plugins-CJM
       version 4.09.

SYNOPSIS

       In dist.ini:

	 [MakeMaker::Custom]
	 eumm_version = 0.34  ; the default comes from the MakeMaker plugin

       In your Makefile.PL:

	 use ExtUtils::MakeMaker;

	 ##{ $share_dir_code{preamble} || '' ##}

	 WriteMakefile(
	   NAME => "My::Module",
	 ##{ $plugin->get_prereqs ##}
	 );

	 ##{ $share_dir_code{postamble} || '' ##}

       Of course, your Makefile.PL should be more complex than that, or you don't need this plugin.

DESCRIPTION

       This plugin is for people who need something more complex than the auto-generated Makefile.PL or Build.PL generated by the MakeMaker or
       ModuleBuild plugins.

       It is a subclass of the MakeMaker plugin, but it does not write a Makefile.PL for you.  Instead, you write your own Makefile.PL, which may
       do anything ExtUtils::MakeMaker is capable of.

       This plugin will process Makefile.PL as a template (using Text::Template), which allows you to add data from Dist::Zilla to the version you
       distribute (if you want).  The template delimiters are "##{" and "##}", because that makes them look like comments.  That makes it easier
       to have a Makefile.PL that works both before and after it is processed as a template.

       This is particularly useful for XS-based modules, because it can allow you to build and test the module without the overhead of
       "dzil build" after every small change.

       The template may use the following variables:

       %default_args
	   The hash of arguments for WriteMakefile generated by the normal MakeMaker plugin.

       $dist
	   The name of the distribution.

       $eumm_version
	   The minimum version of ExtUtils::MakeMaker required (from the "eumm_version" attribute of this plugin).

       %meta
	   The hash of metadata (in META 2 format) that will be stored in META.json.

       $perl_prereq
	   The minimum version of Perl required (from the prerequisites in the metadata).  May be "undef".  Equivalent to
	   $default_args{MIN_PERL_VERSION}.

       $plugin
	   The MakeMaker::Custom object that is processing the template.

       %share_dir_code
	   A hash of strings containing the code for loading "File::ShareDir::Install" (if it's used by this dist).  Put
	   "##{ $share_dir_code{preamble} || '' ##}" after the "use ExtUtils::MakeMaker" line, and put "##{ $share_dir_code{postamble} || '' ##}"
	   after the "WriteMakefile" call.  (You can omit the "|| ''" if you're sure the dist is using File::ShareDir.

	   For backwards compatibility, this code is also available in the array @share_dir_block, but you should update your templates to use
	   %share_dir_code instead.

       $version
	   The distribution's version number.

       $zilla
	   The Dist::Zilla object that is creating the distribution.

METHODS

   get_default
	 $plugin->get_default(qw(key1 key2 ...))

       A template can call this method to extract the specified key(s) from the default WriteMakefile arguments created by the normal MakeMaker
       plugin and have them formatted into a comma-separated list suitable for a hash constructor or a function's parameter list.

       If any key has no value (or its value is an empty hash or array ref) it will be omitted from the list.  If all keys are omitted, the empty
       string is returned.  Otherwise, the result always ends with a comma.

   get_prereqs
	 $plugin->get_prereqs

       This is equivalent to

	 $plugin->get_default(qw(BUILD_REQUIRES CONFIGURE_REQUIRES PREREQ_PM))

       In other words, it returns all the keys that describe the distribution's prerequisites.

SEE ALSO

       The ModuleBuild::Custom plugin does basically the same thing as this plugin, but for Build.PL (if you prefer Module::Build).

       The MakeMaker::Awesome plugin allows you to do similar things to your Makefile.PL, but it works in a very different way.  With
       MakeMaker::Awesome, you subclass the plugin and override the methods that generate Makefile.PL.	In my opinion, MakeMaker::Awesome has two
       disadvantages: it's unnecessarily complex, and it doesn't allow you to build your module without doing "dzil build".  The only advantage of
       MakeMaker::Awesome that I can see is that if you had several dists with very similar Makefile.PLs, you could write one subclass of
       MakeMaker::Awesome and use it in each dist.

DEPENDENCIES

       MakeMaker::Custom requires Dist::Zilla (4.300009 or later) and Text::Template.  I also recommend applying Template_strict.patch to
       Text::Template.	This will add support for the STRICT option, which will help catch errors in your templates.

INCOMPATIBILITIES

       You must not use this in conjunction with the MakeMaker or MakeMaker::Awesome plugins.

BUGS AND LIMITATIONS
