The latter can simply be:
from pyramid.paster import get_app, setup_logging
from waitress import serve
setup_logging(configfile)
application: Router = get_app(configfile, 'main')
serve(app, host='0.0.0.0', port=8088, threads=50)
A file for mod_wsgi is the same but without the last line (application is a keyword).
The pyramid.get_app reads the configfile to get the module to load,
main is the function within michelanglo_app that returns a Router instance.
A Router instance is a callable that accepts an WSGI environment, just like a flask.Flask instance,
hence why both have the methods __call__(environ, start_response) and request_context(environ) ,
but the two have rather different albeit similar inner workings, but their syntax differ dramatically.
The get_app function can also accept an parameter options if there are interpolated variables in the ini file
(not in the default ones).
application = get_app(configfile, 'main', options={'SQL_URL': os.environ['SQL_URL']})
Here is basically a long loop around the config file.
from configparser import ConfigParser
config = ConfigParser()
config.read('/Users/matteo/Coding/michelanglo/app/production.ini')
settings = config['app:main']
import michelanglo_app
application = michelanglo_app.main({}, **settings)
