Zd�Zd�ZRS(s�Represent the database state made available to a migration
    script.

    :class:`.MigrationContext` is the front end to an actual
    database connection, or alternatively a string output
    stream given a particular database dialect,
    from an Alembic perspective.

    When inside the ``env.py`` script, the :class:`.MigrationContext`
    is available via the
    :meth:`.EnvironmentContext.get_context` method,
    which is available at ``alembic.context``::

        # from within env.py script
        from alembic import context
        migration_context = context.get_context()

    For usage outside of an ``env.py`` script, such as for
    utility routines that want to check the current version
    in the database, the :meth:`.MigrationContext.configure`
    method to create new :class:`.MigrationContext` objects.
    For example, to get at the current revision in the
    database using :meth:`.MigrationContext.get_current_revision`::

        # in any application, outside of an env.py script
        from alembic.migration import MigrationContext
        from sqlalchemy import create_engine

        engine = create_engine("postgresql://mydatabase")
        conn = engine.connect()

        context = MigrationContext.configure(conn)
        current_rev = context.get_current_revision()

    The above context can also be used to produce
    Alembic migration operations with an :class:`.Operations`
    instance::

        # in any application, outside of the normal Alembic environment
        from alembic.operations import Operations
        op = Operations(context)
        op.alter_column("mytable", "somecolumn", nullable=True)

        This is a factory method usually called

        :param url: a string database url, or a
         :class:`sqlalchemy.engine.url.URL` object.
         The type of dialect to be used will be derived from this if
         ``connection`` is not passed.
        :param dialect_name: string name of a dialect, such as
         "postgresql", "mssql", etc.  The type of dialect to be used will be
         derived from this if ``connection`` and ``url`` are not passed.
        :param opts: dictionary of options.  Most other options
         accepted by :meth:`.EnvironmentContext.configure` are passed via
         this dictionary.

SdS(s�Return the current revision, usually that which is present
        in the ``alembic_version`` table in the database.

        This method intends to be used only for a migration stream that
        does not contain unmerged branches in the target database;
        if there are multiple branches present, an exception is raised.
        The :meth:`.MigrationContext.get_current_heads` should be preferred
        over this method going forward in order to be compatible with
        branch migration support.

        If this :class:`.MigrationContext` was configured in "offline"
        mode, that is with ``as_sql=True``, the ``starting_rev``
        parameter is returned instead, if any.

S(s�Return a tuple of the current 'head versions' that are represented
        in the target database.

        For a migration stream without branches, this will be a single
        value, synonymous with that of
        :meth:`.MigrationContext.get_current_revision`.   However when multiple
        unmerged branches exist within the target database, the returned tuple
        will contain a value for each head.

        If this :class:`.MigrationContext` was configured in "offline"
        mode, that is with ``as_sql=True``, the ``starting_rev``
        parameter is returned in a one-length tuple.

        If no version table is present, or if there are no revisions
        present, an empty tuple is returned.

ndS(s-Run the migration scripts established for this
        :class:`.MigrationContext`, if any.

        The commands in :mod:`alembic.command` will set up a function
        that is ultimately passed to the :class:`.MigrationContext`
        as the ``fn`` argument.  This function represents the "work"
        that will be done when :meth:`.MigrationContext.run_migrations`
        is called, typically from within the ``env.py`` script of the
        migration environment.  The "work function" then provides an iterable
        of version callables and other version information which
        in the case of the ``upgrade`` or ``downgrade`` commands are the
        list of version scripts to invoke.  Other commands yield nothing,
        in the case that a command wants to run some other operation
        against the database such as the ``current`` or ``stamp`` commands.

        :param \**kw: keyword arguments here will be passed to each
         migration callable, that is the ``upgrade()`` or ``downgrade()``
         method within revision scripts.
