Module::Build::Compat(User Contributed Perl DocumentatModule::Build::Compat(3)
NAME
       Module::Build::Compat - Compatibility with ExtUtils::MakeMaker
SYNOPSIS
         # In a Build.PL :
         use Module::Build;
         my $build = Module::Build->new
           ( module_name => 'Foo::Bar',
             license     => 'perl',
             create_makefile_pl => 'traditional' );
         ...
DESCRIPTION
       Because "ExtUtils::MakeMaker" has been the standard way to distribute
       modules for a long time, many tools (CPAN.pm, or your system
       administrator) may expect to find a working Makefile.PL in every
       distribution they download from CPAN.  If you want to throw them a
       bone, you can use "Module::Build::Compat" to automatically generate a
       Makefile.PL for you, in one of several different styles.
       "Module::Build::Compat" also provides some code that helps out the
       Makefile.PL at runtime.
METHODS
       create_makefile_pl($style, $build)
           Creates a Makefile.PL in the current directory in one of several
           styles, based on the supplied "Module::Build" object $build.  This
           is typically controlled by passing the desired style as the
           "create_makefile_pl" parameter to "Module::Build"'s "new()" method;
           the Makefile.PL will then be automatically created during the
           "distdir" action.
           The currently supported styles are:
           traditional
               A Makefile.PL will be created in the "traditional" style, i.e.
               it will use "ExtUtils::MakeMaker" and won't rely on
               "Module::Build" at all.  In order to create the Makefile.PL,
               we'll include the "requires" and "build_requires" dependencies
               as the "PREREQ_PM" parameter.
               You don't want to use this style if during the "perl Build.PL"
               stage you ask the user questions, or do some auto-sensing about
               the user's environment, or if you subclass "Module::Build" to
               do some customization, because the vanilla Makefile.PL won't do
               any of that.
           small
               A small Makefile.PL will be created that passes all
               functionality through to the Build.PL script in the same
               directory.  The user must already have "Module::Build"
               installed in order to use this, or else they'll get a module-
               not-found error.
           passthrough (DEPRECATED)
               This is just like the "small" option above, but if
               "Module::Build" is not already installed on the user's system,
               the script will offer to use "CPAN.pm" to download it and
               install it before continuing with the build.
               This option has been deprecated and may be removed in a future
               version of Module::Build.  Modern CPAN.pm and CPANPLUS will
               recognize the "configure_requires" metadata property and
               install Module::Build before running Build.PL if Module::Build
               is listed and Module::Build now adds itself to
               configure_requires by default.
               Perl 5.10.1 includes "configure_requires" support.  In the
               future, when "configure_requires" support is deemed
               sufficiently widespread, the "passthrough" style will be
               removed.
       run_build_pl(args => \@ARGV)
           This method runs the Build.PL script, passing it any arguments the
           user may have supplied to the "perl Makefile.PL" command.  Because
           "ExtUtils::MakeMaker" and "Module::Build" accept different
           arguments, this method also performs some translation between the
           two.
           "run_build_pl()" accepts the following named parameters:
           args
               The "args" parameter specifies the parameters that would
               usually appear on the command line of the "perl Makefile.PL"
               command - typically you'll just pass a reference to @ARGV.
           script
               This is the filename of the script to run - it defaults to
               "Build.PL".
       write_makefile()
           This method writes a 'dummy' Makefile that will pass all commands
           through to the corresponding "Module::Build" actions.
           "write_makefile()" accepts the following named parameters:
           makefile
               The name of the file to write - defaults to the string
               "Makefile".
SCENARIOS
       So, some common scenarios are:
       1.  Just include a Build.PL script (without a Makefile.PL script), and
           give installation directions in a README or INSTALL document
           explaining how to install the module.  In particular, explain that
           the user must install "Module::Build" before installing your
           module.
           Note that if you do this, you may make things easier for yourself,
           but harder for people with older versions of CPAN or CPANPLUS on
           their system, because those tools generally only understand the
           Makefile.PL/"ExtUtils::MakeMaker" way of doing things.
       2.  Include a Build.PL script and a "traditional" Makefile.PL, created
           either manually or with "create_makefile_pl()".  Users won't ever
           have to install "Module::Build" if they use the Makefile.PL, but
           they won't get to take advantage of "Module::Build"'s extra
           features either.
           For good measure, of course, test both the Makefile.PL and the
           Build.PL before shipping.
       3.  Include a Build.PL script and a "pass-through" Makefile.PL built
           using "Module::Build::Compat".  This will mean that people can
           continue to use the "old" installation commands, and they may never
           notice that it's actually doing something else behind the scenes.
           It will also mean that your installation process is compatible with
           older versions of tools like CPAN and CPANPLUS.
