                         You can use this to access plugin configuration options via  datasette.plugin_config(your_plugin_name) . 
                     
                 
             
             Magic parameters  can be used to add automatic parameters to  canned queries . This plugin hook allows additional magic parameters to be defined by plugins. 
             Magic parameters all take this format:  _prefix_rest_of_parameter . The prefix indicates which magic parameter function should be called - the rest of the parameter is passed as an argument to that function. 
             To register a new function, return it as a tuple of  (string prefix, function)  from this hook. The function you register should take two arguments:  key  and  request , where  key  is the  rest_of_parameter  portion of the parameter and  request  is the current  Request object . 
             This example registers two new magic parameters:  :_request_http_version  returning the HTTP version of the current request, and  :_uuid_new  which returns a new UUID: 
             from datasette import hookimpl
from uuid import uuid4


def uuid(key, request):
    if key == ""new"":
        return str(uuid4())
    else:
        raise KeyError


def request(key, request):
    if key == ""http_version"":
        return request.scope[""http_version""]
    else:
        raise KeyError
