349 This class models a git repository, referred to in Gitalist
357 The name of the Repository. If unspecified, this will be derived from the path to the git repository.
361 L<Path::Class:Dir> for the filesystem path to the git repository.
365 The contents of .git/description.
369 Owner of the files on the filesystem.
373 The L<DateTime> of the last modification of the repository. This will be C<undef> if the repository has never been used.
377 True if this is a bare git repository.
383 An array of the name and sha1 of all heads/tags in the repository.
387 Hashref of ArrayRefs for each reference.
392 =head2 head_hash ($head?)
394 Return the sha1 for HEAD, or any specified head.
396 =head2 list_tree ($sha1?)
398 Return an array of contents for a given tree.
399 The tree is specified by sha1, and defaults to HEAD.
400 Each item is a L<Gitalist::Git::Object>.
402 =head2 get_object ($sha1)
404 Return an appropriate subclass of L<Gitalist::Git::Object> for the given sha1.
406 =head2 hash_by_path ($sha1, $path, $type?)
408 Returns the sha1 for a given path, optionally limited by type.
410 =head2 list_revs ($sha1, $count?, $skip?, \%search?, $file?)
412 Returns a list of revs for the given head ($sha1).
414 =head2 snapshot ($sha1, $format)
416 Generate an archived snapshot of the repository.
417 $sha1 should be a commit or tree.
418 Returns a filehandle to read from.
420 =head2 diff ($commit, $patch?, $parent?, $file?)
422 Generate a diff from a given L<Gitalist::Git::Object>.
424 =head2 reflog (@lorgargs)
426 Return a list of hashes representing each reflog entry.
428 FIXME Should this return objects?
