Within an ``env.py`` script, this is available via the :attr:`.EnvironmentContext.config` attribute, which in turn is available at ``alembic.context``:: from alembic import context some_param = context.config.get_main_option("my option") When invoking Alembic programatically, a new :class:`.Config` can be created by passing the name of an .ini file to the constructor:: from alembic.config import Config alembic_cfg = Config("/path/to/yourapp/alembic.ini") With a :class:`.Config` object, you can then run Alembic commands programmatically using the directives in :mod:`alembic.command`. The :class:`.Config` object can also be constructed without a filename. Values can be set programmatically, and new sections will be created as needed:: from alembic.config import Config alembic_cfg = Config() alembic_cfg.set_main_option("script_location", "myapp:migrations") alembic_cfg.set_main_option("url", "postgresql://foo/bar") alembic_cfg.set_section_option("mysection", "foo", "bar") For passing non-string values to environments, such as connections and engines, use the :attr:`.Config.attributes` dictionary:: with engine.begin() as connection: alembic_cfg.attributes['connection'] = connection command.upgrade(alembic_cfg, "head") :param file_: name of the .ini file to open. :param ini_section: name of the main Alembic section within the .ini file :param output_buffer: optional file-like input buffer which will be passed to the :class:`.MigrationContext` - used to redirect the output of "offline generation" when using Alembic programmatically. :param stdout: buffer where the "print" output of commands will be sent. Defaults to ``sys.stdout``. .. versionadded:: 0.4 :param config_args: A dictionary of keys and values that will be used for substitution in the alembic config file. The dictionary as given is **copied** to a new one, stored locally as the attribute ``.config_args``. When the :attr:`.Config.file_config` attribute is first invoked, the replacement variable ``here`` will be added to this dictionary before the dictionary is passed to ``SafeConfigParser()`` to parse the .ini file. .. versionadded:: 0.7.0 :param attributes: optional dictionary of arbitrary Python keys/values, which will be populated into the :attr:`.Config.attributes` dictionary. .. versionadded:: 0.7.5 .. seealso:: :ref:`connection_sharing` talembiccCsY||_||_||_||_||_t||_|rU|jj|ndS(s*Construct a new :class:`.Config` N( tconfig_file_nametconfig_ini_sectiont output_buffertstdouttcmd_optstdictt config_argst attributestupdate(tselftfile_t ini_sectionR R R RR((s?/opt/alt/python27/lib/python2.7/site-packages/alembic/config.pyt__init__Us     cCsiS(sA Python dictionary for storage of additional state.
