NAME¶
Dist::Zilla::Plugin::ModuleBuild::Custom - Allow a dist to have a custom
Build.PL
VERSION¶
This document describes version 4.07 of
Dist::Zilla::Plugin::ModuleBuild::Custom, released June 4, 2012 as part of
Dist-Zilla-Plugins-CJM version 4.09.
SYNOPSIS¶
In
dist.ini:
[ModuleBuild::Custom]
mb_version = 0.34 ; the default comes from the ModuleBuild plugin
In your
Build.PL:
use Module::Build;
my $builder = Module::Build->new(
module_name => 'Foo::Bar',
##{ $plugin->get_prereqs ##}
##{ $plugin->get_default('share_dir') ##}
);
$builder->create_build_script;
Of course, your
Build.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 ModuleBuild plugin, but it does not write a
Build.PL for you. Instead, you write your own
Build.PL, which
may do anything Module::Build is capable of (except generate a compatibility
Makefile.PL).
This plugin will process
Build.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
Build.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:
- $dist
- The name of the distribution.
- $meta
- The hash of metadata (in META 1.4 format) that will be
stored in META.yml.
- $meta2
- The hash of metadata (in META 2 format) that will be stored
in META.yml.
- $plugin
- The ModuleBuild::Custom object that is processing the
template.
- $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
Module::Build arguments created by the normal ModuleBuild plugin and have them
formatted into a comma-separated list suitable for a hash constructor or a
method'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.
The most common usage would be
##{ $plugin->get_default('share_dir') ##}
$plugin->get_meta(qw(key1 key2 ...))
A template can call this method to extract the specified key(s) from
"distmeta" and have them formatted into a comma-separated list
suitable for a hash constructor or a method's parameter list. The keys (and
the returned values) are from the META 1.4 spec, because that's what
Module::Build uses in its API.
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_meta(qw(build_requires configure_requires requires
recommends conflicts))
In other words, it returns all the keys that describe the distribution's
prerequisites.
SEE ALSO¶
The MakeMaker::Custom plugin does basically the same thing as this plugin, but
for
Makefile.PL (if you prefer ExtUtils::MakeMaker).
DEPENDENCIES¶
ModuleBuild::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 ModuleBuild plugin.
BUGS AND LIMITATIONS¶
No bugs have been reported.
