The environment will be configured as if it is currently serving ``request``, leaving a natural environment in place to write scripts that can generate URLs and utilize renderers. This function returns a dictionary with ``app``, ``root``, ``closer``, ``request``, and ``registry`` keys. ``app`` is the WSGI app loaded (based on the ``config_uri``), ``root`` is the traversal root resource of the Pyramid application, and ``closer`` is a parameterless callback that may be called when your script is complete (it pops a threadlocal stack). .. note:: Most operations within :app:`Pyramid` expect to be invoked within the context of a WSGI request, thus it's important when loading your application to anchor it when executing scripts and other code that is not normally invoked during active WSGI requests. .. note:: For a complex config file containing multiple :app:`Pyramid` applications, this function will setup the environment under the context of the last-loaded :app:`Pyramid` application. You may load a specific application yourself by using the lower-level functions :meth:`pyramid.paster.get_app` and :meth:`pyramid.scripting.prepare` in conjunction with :attr:`pyramid.config.global_registries`. ``config_uri`` -- specifies the PasteDeploy config file to use for the interactive shell. The format is ``inifile#name``. If the name is left off, ``main`` will be assumed. ``request`` -- specified to anchor the script to a given set of WSGI parameters. For example, most people would want to specify the host, scheme and port such that their script will generate URLs in relation to those parameters. A request with default parameters is constructed for you if none is provided. You can mutate the request's ``environ`` later to setup a specific host/port/scheme/etc. ``options`` Is passed to get_app for use as variable assignments like {'http_port': 8080} and then use %(http_port)s in the config file. See :ref:`writing_a_script` for more information about how to use this function. """ app = get_app(config_uri, options=options) env = prepare(request) env['app'] = app return env
