#pod =head1 DESCRIPTION
#pod
#pod Dist::Zilla builds distributions of code to be uploaded to the CPAN.  In this
#pod respect, it is like L<ExtUtils::MakeMaker>, L<Module::Build>, or
#pod L<Module::Install>.  Unlike those tools, however, it is not also a system for
#pod installing code that has been downloaded from the CPAN.  Since it's only run by
#pod authors, and is meant to be run on a repository checkout rather than on
#pod published, released code, it can do much more than those tools, and is free to
#pod make much more ludicrous demands in terms of prerequisites.
#pod
#pod If you have access to the web, you can learn more and find an interactive
#pod tutorial at B<L<dzil.org|http://dzil.org/>>.  If not, try
#pod L<Dist::Zilla::Tutorial>.

#pod
#pod If the C<$ENV{RELEASE_STATUS}> environment variable exists, its value will

#pod For backwards compatibility, if C<$ENV{RELEASE_STATUS}> does not exist and

=head1 NAME

Dist::Zilla - distribution builder; installer not included!

=head1 VERSION

version 6.008

=head1 DESCRIPTION

Dist::Zilla builds distributions of code to be uploaded to the CPAN.  In this
respect, it is like L<ExtUtils::MakeMaker>, L<Module::Build>, or
L<Module::Install>.  Unlike those tools, however, it is not also a system for
installing code that has been downloaded from the CPAN.  Since it's only run by
authors, and is meant to be run on a repository checkout rather than on
published, released code, it can do much more than those tools, and is free to
make much more ludicrous demands in terms of prerequisites.

If you have access to the web, you can learn more and find an interactive
tutorial at B<L<dzil.org|http://dzil.org/>>.  If not, try
L<Dist::Zilla::Tutorial>.

=head1 ATTRIBUTES

=head2 name

The name attribute (which is required) gives the name of the distribution to be
built.  This is usually the name of the distribution's main module, with the
double colons (C<::>) replaced with dashes.  For example: C<Dist-Zilla>.

=head2 version

This is the version of the distribution to be created.

=head2 release_status

This attribute sets the release status to one of the
L<CPAN::META::Spec|https://metacpan.org/pod/CPAN::Meta::Spec#release_status>
values: 'stable', 'testing' or 'unstable'.

If the C<$ENV{RELEASE_STATUS}> environment variable exists, its value will
be used as the release status.

For backwards compatibility, if C<$ENV{RELEASE_STATUS}> does not exist and
the C<$ENV{TRIAL}> variable is true, the release status will be 'testing'.

Otherwise, the release status will be set from a
L<ReleaseStatusProvider|Dist::Zilla::Role::ReleaseStatusProvider>, if one
has been configured.

For backwards compatibility, setting C<is_trial> true in F<dist.ini> is
equivalent to using a C<ReleaseStatusProvider>.  If C<is_trial> is false,
it has no effect.

Only B<one> C<ReleaseStatusProvider> may be used.

If no providers are used, the release status defaults to 'stable' unless there
is an "_" character in the version, in which case, it defaults to 'testing'.

=head2 abstract

This is a one-line summary of the distribution.  If none is given, one will be
looked for in the L</main_module> of the dist.

=head2 main_module

This is the module where Dist::Zilla might look for various defaults, like
the distribution abstract.  By default, it's derived from the distribution
name.  If your distribution is Foo-Bar, and F<lib/Foo/Bar.pm> exists,
that's the main_module.  Otherwise, it's the shortest-named module in the
distribution.  This may change!

You can override the default by specifying the file path explicitly,
ie:

  main_module = lib/Foo/Bar.pm

=head2 license

This is the L<Software::License|Software::License> object for this dist's
license and copyright.

It will be created automatically, if possible, with the
C<copyright_holder> and C<copyright_year> attributes.  If necessary, it will
try to guess the license from the POD of the dist's main module.

A better option is to set the C<license> name in the dist's config to something
understandable, like C<Perl_5>.

=head2 authors

This is an arrayref of author strings, like this:

  [
    'Ricardo Signes <rjbs@cpan.org>',
    'X. Ample, Jr <example@example.biz>',
  ]

This is likely to change at some point in the near future.

=head2 files

This is an arrayref of objects implementing L<Dist::Zilla::Role::File> that
will, if left in this arrayref, be built into the dist.

Non-core code should avoid altering this arrayref, but sometimes there is not
other way to change the list of files.  In the future, the representation used
for storing files B<will be changed>.

=head2 root

This is the root directory of the dist, as a L<Path::Tiny>.  It will
nearly always be the current working directory in which C<dzil> was run.

=head2 is_trial

This attribute tells us whether or not the dist will be a trial release,
i.e. whether it has C<release_status> 'testing' or 'unstable'.

Do not set this directly, it will be derived from C<release_status>.

=head2 plugins

This is an arrayref of plugins that have been plugged into this Dist::Zilla
object.

Non-core code B<must not> alter this arrayref.  Public access to this attribute
B<may go away> in the future.

=head2 distmeta

This is a hashref containing the metadata about this distribution that will be
stored in META.yml or META.json.  You should not alter the metadata in this
hash; use a MetaProvider plugin instead.

=head2 prereqs

This is a L<Dist::Zilla::Prereqs> object, which is a thin layer atop
L<CPAN::Meta::Prereqs>, and describes the distribution's prerequisites.

=head2 logger

This attribute stores a L<Log::Dispatchouli::Proxy> object, used to log
messages.  By default, a proxy to the dist's L<Chrome|Dist::Zilla::Chrome> is
taken.

The following methods are delegated from the Dist::Zilla object to the logger:

=head1 METHODS

=head2 register_prereqs

Allows registration of prerequisites; delegates to
L<Dist::Zilla::Prereqs/register_prereqs> via our L</prereqs> attribute.

=head2 plugin_named

  my $plugin = $zilla->plugin_named( $plugin_name );

=head2 plugins_with

  my $roles = $zilla->plugins_with( -SomeRole );

This method returns an arrayref containing all the Dist::Zilla object's plugins
that perform the named role.  If the given role name begins with a dash, the
dash is replaced with "Dist::Zilla::Role::"

=head2 find_files

  my $files = $zilla->find_files( $finder_name );

This method will look for a
L<FileFinder|Dist::Zilla::Role::FileFinder>-performing plugin with the given
name and return the result of calling C<find_files> on it.  If no plugin can be
found, an exception will be raised.

=head2 stash_named

  my $stash = $zilla->stash_named( $name );

This method will return the stash with the given name, or undef if none exists.
It looks for a local stash (for this dist) first, then falls back to a global
stash (from the user's global configuration).

=head1 STABILITY PROMISE

None.

I will try not to break things within any major release.  Minor releases are
not extensively tested before release.  In major releases, anything goes,
although I will try to publish a complete list of known breaking changes in any
major release.

If Dist::Zilla was a tool, it would have yellow and black stripes and there
would be no L<UL
certification|https://en.wikipedia.org/wiki/UL_(safety_organization)> on it.
It is nasty, brutish, and large.

=head1 SUPPORT

There are usually people on C<irc.perl.org> in C<#distzilla>, even if they're
idling.

The L<Dist::Zilla website|http://dzil.org/> has several valuable resources for
learning to use Dist::Zilla.
