Description

Hi,
I'd like to use typed-settings https://typed-settings.readthedocs.io/en/latest/guides/click.html#command-line-arguments-with-click with Typer. It has a decorator to generate click options from the settings object see the link to typed-settings.

I tried to include the click app in typer https://typer.tiangolo.com/tutorial/using-click/#including-a-typer-app-in-a-click-app but then I'm essentially using click and not Typer.

Wanted Solution

I would like to be able to add options from typed-settings Object in a similar style as it is described in docs.

It looks like what am I describing is the ability to dynamically set options from an object. I guess it is similar to #305 #86 (comment)

Here is what typed-settings usage looks like

import click
import os
import typed_settings as ts

os.environ['EXAMPLE_SPAM'] = "23"

@ts.settings
class Settings:
    spam: int = 42

@click.command()
@ts.click_options(Settings, "example")
def cli(settings: Settings):
    print(settings)
    
# As you can see, an option is generated for each setting:

import click.testing

runner = click.testing.CliRunner()
print(runner.invoke(cli, ["--help"]).output)

output

Usage: cli [OPTIONS]

Options:
  --spam INTEGER  [default: 23]
  --help          Show this message and exit.

print(runner.invoke(cli, ["--spam=3"]).output)
Settings(spam=3)

Wanted Code

import typer
import os

os.environ['EXAMPLE_SPAM'] = "23"

import typed_settings as ts


@ts.settings
class Settings:
    spam: int = 42



app = typer.Typer()


@app.command()
def dynamic_options(settings:Settings=typer.Options()):  # load options from the class
    print(settings)
