cpanfile - A format for describing CPAN dependencies for Perl applications
=head1 SYNOPSIS
requires 'Catalyst', '5.8000'; # 5.8000 or newer
requires 'Catalyst::View::JSON', '>= 0.30, < 0.40';
recommends 'JSON::XS', '2.0';
conflicts 'JSON', '< 1.0';
on 'test' => sub {
requires 'Test::More', '>= 0.96, < 2.0';
recommends 'Test::TCP', '1.12';
};
on 'develop' => sub {
recommends 'Devel::NYTProf';
};
feature 'sqlite', 'SQLite support' => sub {
recommends 'DBD::SQLite';
};
=head1 VERSION
This doucment describes cpanfile format version 1.0.
=head1 DESCRIPTION
C<cpanfile> describes CPAN dependencies required to execute associated
Perl code.
=head1 SYNTAX
=over 4
=item requires, recommends, suggests, conflicts
requires $module, $version_requirement;
Describes the requirement for a module. See L<CPAN::Meta::Spec> for
the meanings of each requirement type.
When version requirement is omitted, it is assumed that C<0> is
passed, meaning any version of the module would satisfy the
requirement.
Version requirement can either be a version number or a string that
satisfies L<CPAN::Meta::Spec/Version Ranges>, such as C<< >= 1.0, !=
1.1 >>.
Note that, per L<CPAN::Meta::Spec>, when a plain version number is
given, it means the version I<or newer> is required. If you want a
specific version for a module, use the specific range syntax, i.e.
C< == 2.1 >.
=item on
on $phase => sub { ... };
Describe requirements for a specific phase. Available phases are
C<configure>, C<build>, C<test>, C<runtime> and C<develop>.
=item feature
feature $identifier, $description => sub { ... };
Group requirements with features. Description can be omitted, when it
is assumed to be the same as identifier. See
L<CPAN::Meta::Spec/optional_features> for more details.
=item configure_requires, build_requires, test_requires, author_requires
configure_requires $module, $version;
# on 'configure' => sub { requires $module, $version }
build_requires $module, $version;
# on 'build' => sub { requires $module, $version };
test_requires $module, $version;
# on 'test' => sub { requires $module, $version };
author_requires $module, $version;
# on 'develop' => sub { requires $module, $version };
Shortcut for C<requires> in specific phase. This is mainly provided
for compatibilities with L<Module::Install> DSL.

=head1 USAGE
C<cpanfile> is a format to describe dependencies. How to use this file
is dependent on the tools reading/writing it.
Usually, you're expected to place the C<cpanfile> in the root of the
directory containing the associated code.
Tools supporting C<cpanfile> format (e.g. L<cpanm> and L<carton>) will
automatically detect the file and install dependencies for the code to
run.
There are also tools to support converting cpanfile to CPAN toolchain
compatible formats, such as L<Module::CPANfile>,
L<Dist::Zilla::Plugin::Prereqs::FromCPANfile>,
L<Module::Install::CPANfile>, so that C<cpanfile> can be used to
describe dependencies for a CPAN distribution as well.

=head1 ACKNOWLEDGEMENTS
The format (DSL syntax) is inspired by L<Module::Install> and
L<Module::Build::Functions>.
C<cpanfile> specification (this document) is based on Ruby's
L<Gemfile|http://bundler.io/v1.3/man/gemfile.5.html> specification.
