Bumps typer from 0.27.3 to 0.29.0.

Release notes

Sourced from typer's releases.

0.29.0

Features

  • ✨ Use Pydantic for parameter validation. PR #1831 by @​svlandeg.

    Typer now uses Pydantic internally to validate command-line parameters. This is a gradual migration focused on preserving compatibility with existing Typer applications. Some validation error messages, help text, and usage output have changed.

    Compatibility changes:

    • Pydantic >=2.5.3 is now a required dependency.
    • click_type has been removed from typer.Option() and typer.Argument(). New ways to provide custom types will be provided with Pydantic, with much more flexibility.
    • Some defaults are now validated more strictly. The previous tuple example's (None, None, None) default now fails validation. Use tuple[str, int, bool] | None with a default of None and check for None before unpacking, as shown in the updated tuple example. This also makes the code more correct, so you could consider this a bug fix, but if you depended on this behavior, there's a change needed in your code.
    • Default datetime parsing now follows Pydantic's rules, accepting Unix timestamps, timezone offsets, and fractional seconds.
    • Callback parameter objects no longer expose Click's .type, .make_metavar(), .human_readable_name, or .type_cast_value(). Custom integrations using these need updating.

Fixes

  • 🐛 Escape terminal controls in Pydantic validation errors. PR #2005 by @​tiangolo.

0.28.0

Fixes

  • 🐛 Ensure that the default option name is not changed by setting a metavar. PR #1957 by @​svlandeg.
