Example Code

import typer
from typing_extensions import Annotated

app = typer.Typer(rich_markup_mode="rich")


@app.command()
def hello(
    name: Annotated[
        str, typer.Option(help="The [bold]cool[/bold] name of the [green]user[/green]")
    ],
):
    """
    Say [bold]hi[/bold] to the user.
    """
    print(f"Hello {name}")


@app.command()
def goodbye(
    name: Annotated[
        str, typer.Option(help="The [bold]cool[/bold] name of the [green]user[/green]")
    ],
):
    """
    Say [bold]goodbye[/bold] to the user.
    """
    print(f"Goodbye {name}")

if __name__ == "__main__":
    app()

Description

• Create this script in main.py

• In Zsh, start running it with the typer command, start typing: typer main.py run , then hit tab to trigger autocompletion, it shows the two commands, which is correct:

• goodbye

• hello

But their Zsh help string includes the Rich markup content:

$ typer main.py run <tab>

goodbye  -- Say [bold]goodbye[/bold] to the user.
hello    -- Say [bold]hi[/bold] to the user.

It should show plaintext without [bold] markup parts... or better, it should render those parts and show them in actual green color (using the terminal color codes, etc, the stuff Rich does).

Operating System

Linux, macOS

Operating System Details

This applies mainly to Zsh, the behavior might be similar or different in PowerShell. It only applies in shells that can show autocompletion of commands with help sections.
