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.

I submitted a PR #877 that at least should adress removing the tags from the output.

If anyone wants to test the PR, I'd appreciate it! Just let me know which OS and shell you're on, and fill in the following boxes for your system:

• Shows Rich tags in completion text with master
• Removes Rich tags in completion text with PR 877
• Shell is able to show Rich formatting in simple script
• Shows Rich formatting in completion text with PR 877

A simple script you can use to double check whether your console supports Rich formatting, is the following:

    from rich.console import Console

    description = "The [bold]name[/bold] of the [green]user[/green]"

    console = Console()
    console.print(description)
