How to pass argparse argument to a sanic route?

Question

I wish to pass an argparse argument to a function with decorators. What is the strategy here? How can I achieve this without global variables?

#!/usr/bin/env python3
from sanic import Sanic, views, response
import os
import argparse

app = Sanic(__name__)

@app.route('/<var:var>')
async def get(self, request, var):
    print(path)
    return response.text(var)

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument("-p", "--path",
                        help="Set the server root path",
                        action="store")
    args = parser.parse_args()

    app.run(host='0.0.0.0', port=8000)

I also tried using the view HTTPMethodView but without success

Okay so you could dynamically change the function for that route based on the parse arguments... Like this (sorry I'm on my phone)

#!/usr/bin/env python3 
from sanic import Sanic, views, response 
import os 
import argparse 

app = Sanic(__name__)

@app.route('/<var:var>') 
async def get(self, request, var): 
    print(path)
    return response.text(var) 

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument("-p", "--path", help="Set the server root path", action="store")
    args = parser.parse_args()

    def get(var):
        # use args.p in your route function!!

    app.view_functions["/<var:var>"] = get
    app.run(host='0.0.0.0', port=8000)

Might be some mistakes but you should get the gist of it
