"NOVUS ORDO SECLORUM"
A simple meta framework for webapps and services atop the pyramid framework.
Prism provides a context manager based configurator (example taken from Bambino):
from prism import configurator
def main(global_config, settings):
this = 'Bambino'
with prism.configurator(appname=this,
global_config=global_config,
settings=settings) as config:
config.add_translation_dirs('locale/')
config.scan('bambino.views')
return config.wsgiapp
The configurator scans the settings for the following keys:
prism.root_class = prism.resource.App.factory prism.request = prism.request.Request.factory prism.stack = prism.plugins.boilerplate bambino.plugins.appenv bambino.plugins.socketio
prism.root_class:
A specification for a callable for creating an application root object and/or the root factory. This callable accepts the configurator as it's only argument and returns either a callable or an object w/ an attr 'root_factory' that will be registered as the context root factory.
prism.request
A specification that will return a callable that takes the configurator as an argument and returns an object that may be registered as a request factory.
prism.stack
A list of plugins: modules that provide at least a includeme callable and optionally callable "hooks".
- modify_settings: configurator, settings
- modify_resource_tree: configurator, app_root
- after_user_config: configurator

Some generic base classes and interfaces for use with the prism configurator. These are intended for applications that will build a traversal tree at initial time (and extend it depending on request behavior). This useful if one wants to implement a polyglot persistence strategy or simple stateless apps where it does not make sense to hit a cache or persistence layer to render basic traversal structure.
