Dist::Zilla::Plugin::MakeMaker::Custom - Allow a dist to have a custom Makefile.PL
This document describes version 4.26 of Dist::Zilla::Plugin::MakeMaker::Custom, released December 17, 2017 as part of Dist-Zilla-Plugins-CJM version 6.000.
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} || '' ##}
my %args = (
NAME => "My::Module",
##{ $plugin->get_default(qw(ABSTRACT AUTHOR LICENSE VERSION)) ##}
##{ $plugin->get_prereqs(1) ##}
);
unless ( eval { ExtUtils::MakeMaker->VERSION(6.63_03) } ) {
my $tr = delete $args{TEST_REQUIRES};
my $br = $args{BUILD_REQUIRES};
for my $mod ( keys %$tr ) {
if ( exists $br->{$mod} ) {
$br->{$mod} = $tr->{$mod} if $tr->{$mod} > $br->{$mod};
}
else {
$br->{$mod} = $tr->{$mod};
}
}
} # end unless ExtUtils::MakeMaker is 6.63_03 or newer
unless ( eval { ExtUtils::MakeMaker->VERSION(6.56) } ) {
my $br = delete $args{BUILD_REQUIRES};
my $pp = $args{PREREQ_PM};
for my $mod ( keys %$br ) {
if ( exists $pp->{$mod} ) {
$pp->{$mod} = $br->{$mod} if $br->{$mod} > $pp->{$mod};
}
else {
$pp->{$mod} = $br->{$mod};
}
}
} # end unless ExtUtils::MakeMaker is 6.56 or newer
delete $args{CONFIGURE_REQUIRES}
unless eval { ExtUtils::MakeMaker->VERSION(6.52) };
delete $args{LICENSE}
unless eval { ExtUtils::MakeMaker->VERSION(6.31) };
WriteMakefile(%args);
##{ $share_dir_code{postamble} || '' ##}
Of course, your Makefile.PL doesn't need to look exactly like this. If you increase the minimum version of ExtUtils::MakeMaker, you can remove any "unless eval" sections whose version test is less than or equal to "eumm_version". If you're not using "share_dir", you can remove those lines.
And if you're not adding your own code to Makefile.PL, you don't need this plugin.
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:
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.
If you are using the AutoPrereqs plugin, then you will probably want to set its "configure_finder" to a FileFinder that includes Makefile.PL. You may also want to set this plugin's "eumm_version" parameter to 0 and allow AutoPrereqs to get the version from your "use ExtUtils::MakeMaker" line.
Example dist.ini configuration:
[MakeMaker::Custom] eumm_version = 0 ; AutoPrereqs gets actual version from Makefile.PL [FileFinder::ByName / :MakefilePL] file = Makefile.PL [AutoPrereqs] :version = 4.300005 ; need configure_finder configure_finder = :MakefilePL ; Add next line if your Makefile.PL uses modules you ship in inc/ configure_finder = :IncModules
Then in your Makefile.PL you'd say:
use ExtUtils::MakeMaker 6.32; # or whatever version you need
$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.
$plugin->get_prereqs($api_version);
This is mostly equivalent to
$plugin->get_default(qw(BUILD_REQUIRES CONFIGURE_REQUIRES PREREQ_PM
TEST_REQUIRES))
In other words, it returns all the keys that describe the distribution's prerequisites. The $api_version indicates what keys the template can handle. The currently defined values are:
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.
MakeMaker::Custom requires Dist::Zilla (6 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.
You must not use this in conjunction with the MakeMaker or MakeMaker::Awesome plugins.
