Example Code

import typer

app = typer.Typer(rich_markup_mode=None)

@app.command()
def main(name: str):
    typer.echo(f"Hello {name}")

if __name__ == "__main__":
    app()

Description

When rich_markup_mode is set to None, the help message has extra backslashes:

Arguments:
  NAME  \[required]

This seems to have been caused by the escaping done in 5996fc1 when Rich is detected. However, in my case, even though I have Rich installed, I have explicitly set rich_markup_mode to None.

Thanks for the report, we'll look into it! 🙏

[seowalex]

This seems to still be present in latest version.

[svlandeg]

That's most likely true, as we haven't had time to look into this one yet, but it's definitely high on my queue! Thanks for your patience 🙏

[seowalex]

No worries, just checking in! Typer is fantastic to use otherwise.

As an update: I've been able to reproduce this, track it back to the PR you mentioned, and created a test to capture the correct behaviour. Now looking into fixing this while keeping the intended functionality from #847 as well.
