Prevent CLI from loading on import of robyn module about robyn

[sansyrox]

Hey @LilyRose2798 👋

Thanks for creating this issues and bringing this to my attention.

It currently looks to be impossible to implement your own argument parser when using Robyn, as just importing the robyn module creates its own ArgumentParser

Let me dive a bit deeper and come back with an approach to tackle this.

IMO, The one way we can tackle this is to rewrite Robyn whole CLI api, where we expose the functions like workers, debug etc. to the Robyn() class and the seprate logic for CLI. Something similar to uvicorn or flask

A way around the issue I found that isn't ideal is to move the Robyn import to after I've declared my own ArgumentParser:

from argparse import ArgumentParser, Namespace

parser = ArgumentParser("myapi")
parser.add_argument("-a", "--address", default = "127.0.0.1", help = "the address to use for the api (default: %(default)s)")
parser.add_argument("-p", "--port", default = 8000, type = int, help = "the port to use for the api (default: %(default)s)")
parser.add_argument("-l", "--limit", default = 3600, type = int, help = "the number of requests per hour to limit usage of the api to (default: %(default)s)")
parser.add_argument("--processes", default = 1, type = int, help = "the number of processes to use for the api (default: %(default)s)")
parser.add_argument("--workers", default = 1, type = int, help = "the number of workers to use for the api (default: %(default)s)")
parser.add_argument("--log-level", default = "INFO", help = "the log level use for the api (default: %(default)s)")
args = parser.parse_args()

from robyn import Robyn

app = Robyn(__file__, Namespace(**{
    "processes": args.processes,
    "workers": args.workers,
    "dev": False,
    "create": False,
    "docs": False,
    "open_browser": False,
    "version": False,
    "compile_rust_path": None,
    "create_rust_file": None,
    "log_level": args.log_level,
}))

# API routes declared here...

app.start(host = args.address, port = args.port)
