Example Code

from typing import Annotated
import typer
from typer.rich_utils import MARKUP_MODE_MARKDOWN

app = typer.Typer(rich_markup_mode=MARKUP_MODE_MARKDOWN)

@app.command()
def sub(
    user: Annotated[
        str,
        typer.Option(
            "-u",
            "--user",
            help="The name of the user.",
            envvar="USERNAME",
        ),
    ] = "exampleuser",
):
    print(user)
if __name__ == "__main__":
    app()

Description

When running the above code with --help:

desired output (also the output with rich_markup_mode="rich"):

--user -u  STR  Name of the User [env var: USERNAME] [default: exampleuser]

actual output:

--user -u STR  Name of the User
              [env var: USERNAME]
              [default: exampleuser]

(The env var and default values are below the help text. I dont know if this markdown formatting keeps the alignment correct.)

The smallest monkey patch I could find to fix it was in rich_utils.py line 283 by forcing
markup_mode="rich" in the call to _make_rich_text(). This is in _get_parameter_help().
This forces the help text to be a Text instead of a Markdown Renderable.

Thanks for Typer!
