Example Code

import typer
from enum import Enum

app = typer.Typer()

class Product(str, Enum):
    toy = "toy"
    phone ="phone"
     
@app.command("toy")
# called with "python3 main.py test toy"
def toy_test(product: str = Product.toy, sn: str = typer.Option(..., prompt="Please input the Serial Number")):
    print("Testing toy product")
    print("SN is: ", sn)

@app.command("phone")
# called with "python3 main.py test phone"
def phone_test(product: str = Product.phone, sn: str = typer.Option(..., prompt="Please input the Serial Number")):
    print("Testing phone product")
    print("SN is: ", sn)

@app.command(None)
# called with just "python3 main.py test"
def choose_product(product: Product = typer.Option(..., prompt="Please choose the Product type -")
   if product == "toy":
      typer.run(toy_test)
   if product == "phone":
      typer.run(phone_test)

Description

Forgive me if this question seems simple or has been answered before,

I would like to be able to run my cli with a command name which would correspond to testing the product of choice, but would also like the freedom of inputting no command and letting me choose the product.

I have a nested cli with "main.add_typer(test_cli, name='test')"

• main.py
  • test_cli.py

For example, if my code above was called test_cli.py, I would like to run
"python3 main.py test toy" -- this would test the toy product
but if I run
"python3 main.py test" -- this would ask me to choose which product to test and would then run the corresponding test function as if it was run from the command line (so all the Options/Arguments will be asked)

I have tried using name == "test_cli" but that runs with or without a command.

Is this possible?
