=head1 NAME

Moose::Manual::Contributing - How to get involved in Moose

=head1 GETTING INVOLVED

Moose is a pretty open project and we are always willing to accept bug
fixes, more tests and doc patches. Doing these things is as simple as
cloning a copy of the git repository and hacking.

Commit bits are given out freely. All we ask is that for any
non-trivial code patches, you check with one of the core developers
before applying said patch.

Alternatively, you can make a new branch with your change and push it
back to the Moose git server, then ask a core dev to review your
branch.

=head2 IRC and Email

A B<lot> of Moose discussion happens on IRC. We have two channels on
irc.perl.org, #moose and #moose-dev. The former is much more active,
but the core developers pay attention to both channels.

We also have a mailing list, moose@perl.org and all the core
developers read and respond to messages on that list.

=head1 NEW FEATURES

Moose already has a fairly large feature set and we are currently
B<not> looking to add any major new features to it. If you have an
idea for a new feature in Moose, you are invited instead to create a
MooseX module first.

At this stage, no new features will even be considered for addition
into the core without first being vetted as a MooseX module, unless
it is absolutely 100% impossible to implement the feature outside the
core.

If you think it is 100% impossible, you're probably wrong. However,
your feature may need a small hook in the core, or a refactoring of
some core modules, and we are definitely open to that.

Moose was built from the ground up with the idea of being highly
extensible, and quite often the feature requests we see can be
implemented through a couple of small and well placed extensions. Try
it, it is much easier then you might think.

=head1 TESTS, TESTS, TESTS

If you write I<any> code for Moose or Class::MOP, you B<must> add
tests for that code. If you do not write tests then we cannot
guarantee your change will not be removed or altered at a later date.

If your code change/addition is deep within the bowels of
Moose/Class::MOP and your test exercises this feature in a non-obvious
way, please add some comments either near the code in question or in
the test so that others know.

We also greatly appreciate documentation to go with your changes, and
an entry in the Changes file. Make sure to give yourself credit!

=head1 BACKWARDS COMPATIBILITY

Change is inevitable and Moose is not immune to this. We do our best
to maintain backwards compatibility, but we do not want the code base
to become overburdened by this. This is not to say that we will be
frivolous with our changes, quite the opposite, just that we are not
afraid of change and will do our best to keep it as painless as
possible for the end user.

The rule is that if you do something that is not backwards compatible
you B<must> do I<at least> one deprecation cycle (more if it is larger
change). For really larger or radical changes dev releases may be
needed as well (the core developers will decide on this on a
case-per-case basis).

The preference with regard to deprecation is to warn loudly and often
so that users will have time to fix their usages.

All backwards incompatible changes B<must> be documented in
L<Moose::Manual::Delta>. Make sure to document any useful tips or
workarounds for the change in that document.
