Call expression in type expression when defining list of allowed values for slash_command parameter

[seyfu-t]

I was wondering if there is a python-spec compliant way of creating slash commands with a restricted list of values for a given parameter

I have a situation like this here:

    @bot.slash_command()
    async def recommend(
        context: ApplicationContext, 
        genre: Option(str, description="Choose a genre", choices=["thriller", "horror", "action"]),
    ):
        ...

At runtime this works fine, but due to the nature of the type of genre being an expression Pyright will warn you
"Call expression not allowed in type expression"

You can use the @option decorator instead.

from discord import option
from typing import Literal


@bot.slash_command()
@option("option_name", type=str, description="Choose a genre", choices=["thriller", "horror", "action"])
async def command(ctx, option_name: Literal["category1", "category2", "category3"]):
    ...

I hope this answers your question.
