NAME ^

Dist::Zilla::Plugin::MakeMaker::Awesome - A more awesome MakeMaker plugin for Dist::Zilla

VERSION ^

version 0.24

SYNOPSIS ^

In your dist.ini:

    [MakeMaker::Awesome]
    WriteMakefile_arg = CCFLAGS => `pkg-config --cflags libpng`
    WriteMakefile_arg = LIBS => [ `pkg-config --libs libpng` ]

or:

    ;; Replace [MakeMaker]
    ;[MakeMaker]
    [=inc::MyMakeMaker]

DESCRIPTION ^

Dist::Zilla's MakeMaker plugin is limited, if you want to stray from the marked path and do something that would normally be done in a package MY section or otherwise run custom code in your Makefile.PL you're out of luck.

This plugin is 100% compatible with Dist::Zilla::Plugin::MakeMaker -- we add additional customization hooks by subclassing it.

CONFIGURATION OPTIONS ^

Many features can be accessed directly via dist.ini, by setting options. For options where you expect a multi-line string to be inserted into Makefile.PL, use the config option more than once, setting each line separately.

WriteMakefile_arg

A string, which evaluates to an even-numbered list, which will be included in the call to WriteMakefile. Any code is legal that can be inserted into a list of other key-value pairs, for example:

    [MakeMaker::Awesome]
    WriteMakefile_arg = ( $^O eq 'solaris' ? ( CCFLAGS => '-Wall' ) : ())

Can be used more than once.

Note: you (intentionally) cannot use this mechanism for specifying dynamic prerequisites, as previous occurrences of a top-level key will be overwritten (additionally, you cannot set the fallback prereqs from here). You should take a look at [DynamicPrereqs] for this.

test_file

A glob path given to the test => { TESTS => ... } parameter for "WriteMakefile" in ExtUtils::MakeMaker. Can be used more than once. Defaults to .t files under t/. NOT a directory name, despite the name.

exe_file

The file given to the EXE_FILES parameter for "WriteMakefile" in ExtUtils::MakeMaker. Can be used more than once. Defaults to using data from :ExecDir plugins.

SUBCLASSING ^

You can further customize the content of Makefile.PL by subclassing this plugin, Dist::Zilla::Plugin::MakeMaker::Awesome.

As an example, adding a package MY section to your Makefile.PL:

In your dist.ini:

    [=inc::MyDistMakeMaker / MyDistMakeMaker]

Then in your inc/MyDistMakeMaker.pm, real example from Hailo (which has [=inc::HailoMakeMaker / HailoMakeMaker] in its dist.ini):

    package inc::HailoMakeMaker;
    use Moose;

    extends 'Dist::Zilla::Plugin::MakeMaker::Awesome';

    override _build_MakeFile_PL_template => sub {
        my ($self) = @_;
        my $template = super();

        $template .= <<'TEMPLATE';
    package MY;

    sub test {
        my $inherited = shift->SUPER::test(@_);

        # Run tests with Moose and Mouse
        $inherited =~ s/^test_dynamic :: pure_all\n\t(.*?)\n/test_dynamic :: pure_all\n\tANY_MOOSE=Mouse $1\n\tANY_MOOSE=Moose $1\n/m;

        return $inherited;
    }
    TEMPLATE

        return $template;
    };

    __PACKAGE__->meta->make_immutable;

Or maybe you're writing an XS distro and want to pass custom arguments to WriteMakefile(), here's an example of adding a LIBS argument in re::engine::PCRE (note that you can also achieve this without subclassing, by passing the "WriteMakefile_arg" option):

    package inc::PCREMakeMaker;
    use Moose;

    extends 'Dist::Zilla::Plugin::MakeMaker::Awesome';

    override _build_WriteMakefile_args => sub { +{
        # Add LIBS => to WriteMakefile() args
        %{ super() },
        LIBS => [ '-lpcre' ],
    } };

    __PACKAGE__->meta->make_immutable;

And another example from re::engine::Plan9, which determines the arguments dynamically at build time:

    package inc::Plan9MakeMaker;
    use Moose;

    extends 'Dist::Zilla::Plugin::MakeMaker::Awesome';

    override _build_WriteMakefile_args => sub {
        my ($self) = @_;

        our @DIR = qw(libutf libfmt libregexp);
        our @OBJ = map { s/\.c$/.o/; $_ }
                   grep { ! /test/ }
                   glob "lib*/*.c";

        return +{
            %{ super() },
            DIR           => [ @DIR ],
            INC           => join(' ', map { "-I$_" } @DIR),

            # This used to be '-shared lib*/*.o' but that doesn't work on Win32
            LDDLFLAGS     => "-shared @OBJ",
        };
    };

    __PACKAGE__->meta->make_immutable;

If you have custom code in your ExtUtils::MakeMaker-based Makefile.PL that Dist::Zilla can't replace via its default facilities you'll be able to replace it by using this module.

Even if your Makefile.PL isn't ExtUtils::MakeMaker-based you should be able to override it. You'll just have to provide a new "_build_MakeFile_PL_template".

OVERRIDABLE METHODS

These are the methods you can currently override or method-modify in your custom inc/ module. The work that this module does is entirely done in small modular methods that can be overridden in your subclass. Here are some of the highlights:

_build_MakeFile_PL_template

Returns a Text::Template string used to construct the Makefile.PL.

If you need to insert some additional code to the beginning or end of Makefile.PL (without modifying the existing content, you should use an around method modifier, something like this:

    around _build_MakeFile_PL_template => sub {
        my $orig = shift;
        my $self = shift;

        my $NEW_CONTENT = ...;

        # insert new content near the beginning of the file, preserving the
        # preamble header
        my $string = $self->$orig(@_);
        $string =~ m/use warnings;\n\n/g;
        return substr($string, 0, pos($string)) . $NEW_CONTENT . substr($string, pos($string));
    };

_build_WriteMakefile_args

A HashRef of arguments that will be passed to ExtUtils::MakeMaker's WriteMakefile function.

_build_WriteMakefile_dump

Takes the return value of "_build_WriteMakefile_args" and constructs a Str that will be included in the Makefile.PL by "_build_MakeFile_PL_template".

_build_test_files

The glob paths given to the test => { TESTS => ... } parameter for "WriteMakefile" in ExtUtils::MakeMaker. Defaults to .t files under t/. NOT directories, despite the name.

_build_exe_files

The files given to the EXE_FILES parameter for "WriteMakefile" in ExtUtils::MakeMaker. Defaults to using data from :ExecDir plugins.

register_prereqs

gather_files

setup_installer

The test/bin/share dirs and exe_files. These will all be passed to /"_build_WriteMakefile_args" later.

_build_share_dir_block

An ArrayRef[Str] with two elements to be used by "_build_MakeFile_PL_template". The first will declare your sharedir and the second will add a magic package MY section to install it. Deep magic.

OTHER

The main entry point is setup_installer via the Dist::Zilla::Role::InstallTool role. There are also other magic Dist::Zilla roles, check the source for more info.

DIAGNOSTICS ^

attempt to add Makefile.PL multiple times

This error from Dist::Zilla means that you've used both [MakeMaker] and [MakeMaker::Awesome]. You've either included MakeMaker directly in dist.ini, or you have plugin bundle that includes it. See @Filter for how to filter it out.

BUGS ^

This plugin would suck less if Dist::Zilla didn't use a INI-based config system so you could add a stuff like this in your main configuration file like you can with Module::Install.

The .ini file format can only support key-value pairs whereas any complex use of ExtUtils::MakeMaker requires running custom Perl code and passing complex data structures to WriteMakefile.
