=head1 NAME

Gitalist::Git::Repository - Model of a git repository

=head1 SYNOPSIS

    my $gitrepo = dir('/repo/base/Gitalist');
    my $repository = Gitalist::Git::Repository->new($gitrepo);
     $repository->name;        # 'Gitalist'
     $repository->path;        # '/repo/base/Gitalist/.git'
     $repository->description; # 'Unnamed repository.'

=head1 DESCRIPTION

This class models a git repository, referred to in Gitalist
as a "Repository".


=head1 ATTRIBUTES

=head2 name

The name of the Repository.  If unspecified, this will be derived from the path to the git repository.

=head2 path

L<Path::Class:Dir> for the filesystem path to the git repository.

=head2 description

The contents of .git/description.

=head2 owner

Owner of the files on the filesystem.

=head2 last_change

The L<DateTime> of the last modification of the repository.  This will be C<undef> if the repository has never been used.

=head2 is_bare

True if this is a bare git repository.

=head2 heads

=head2 tags

An array of the name and sha1 of all heads/tags in the repository.

=head2 references

Hashref of ArrayRefs for each reference.


=head1 METHODS

=head2 head_hash ($head?)

Return the sha1 for HEAD, or any specified head.

=head2 list_tree ($sha1?)

Return an array of contents for a given tree.
The tree is specified by sha1, and defaults to HEAD.
Each item is a L<Gitalist::Git::Object>.

=head2 get_object ($sha1)

Return an appropriate subclass of L<Gitalist::Git::Object> for the given sha1.

=head2 hash_by_path ($sha1, $path, $type?)

Returns the sha1 for a given path, optionally limited by type.

=head2 list_revs ($sha1, $count?, $skip?, \%search?, $file?)

Returns a list of revs for the given head ($sha1).

=head2 snapshot ($sha1, $format)

Generate an archived snapshot of the repository.
$sha1 should be a commit or tree.
Returns a filehandle to read from.

=head2 diff ($commit, $patch?, $parent?, $file?)

Generate a diff from a given L<Gitalist::Git::Object>.

=head2 reflog (@lorgargs)

Return a list of hashes representing each reflog entry.

FIXME Should this return objects?
