.. automethod:: pygit2.Repository.lookup_reference

Example::

    >>> all_refs = repo.listall_references()
    >>> master_ref = repo.lookup_reference("refs/heads/master")
    >>> commit = master_ref.get_object() # or repo[master_ref.target]

Branches
====================

Branches inherit from References, and additionally provide spetialized
accessors for some unique features.

.. automethod:: pygit2.Repository.listall_branches
.. automethod:: pygit2.Repository.lookup_branch
.. automethod:: pygit2.Repository.create_branch

Example::

    >>> local_branches = repo.listall_branches()
    >>> # equivalent to
    >>> local_branches = repo.listall_branches(pygit2.GIT_BRANCH_LOCAL)

    >>> remote_branches = repo.listall_branches(pygit2.GIT_BRANCH_REMOTE)

    >>> all_branches = repo.listall_branches(pygit2.GIT_BRANCH_REMOTE |
                                             pygit2.GIT_BRANCH_LOCAL)

    >>> master_branch = repo.lookup_branch('master')
    >>> # equivalent to
    >>> master_branch = repo.lookup_branch('master',
                                           pygit2.GIT_BRANCH_LOCAL)

    >>> remote_branch = repo.lookup_branch('upstream/feature',
                                           pygit2.GIT_BRANCH_REMOTE)
