Can you describe from a docs pov what you're trying to do?

I am tryiing to acheave compatibility so url can be in setting class (pulled from .env files or enviroment or other sources)

from pydantic_settings import BaseSettings
from httpx import URL


class Settings(BaseSettings):
    url: URL 



CONFIG = Settings()
AsyncClient = AsyncClient(base_url=CONFIG.url)

alternative is to support AnyUrl from pydantic

Okay, can you provide an example of what the above does and then show why httpx would need to be modified in order to accomodate it?

Trick is it does not need to modified... it just would be nice to do it Here (and can be done other way around (extending URL from HTTPX in pydantic) it is mostly for better convinience

demo without change

import os

from pydantic_settings import BaseSettings
from pydantic import AnyUrl
from httpx import AsyncClient


class Settings(BaseSettings):
    url: AnyUrl


# assume this is in .env file
os.environ["url"] = "http://localhost"

CONFIG = Settings()

client = AsyncClient(base_url=str(CONFIG.url))

here is demo with change

import os

from pydantic_settings import BaseSettings
from httpx import URL, AsyncClient


class Settings(BaseSettings):
    url: URL


# assume this is in .env file
os.environ["url"] = "http://localhost"

CONFIG = Settings()

client = AsyncClient(base_url=CONFIG.url)
