This release adds deep integrations with Rich. ✨

rich is an optional dependency, you can install it directly or it will be included when you install with:

$ pip install "typer[all]"

If Rich is available, it will be used to show the content from --help options, validation errors, and even errors in your app (exception tracebacks).

There are new options to group commands, CLI arguments, and CLI options, support for Rich Console Markup, and more! 🎉

Features

0.3.0

• Add support for help parameter in CLI arguments:
  • As help in CLI arguments is not supported by Click, there are two new internal classes (Click sub-classes) to support it:
    • typer.core.TyperArgument
    • typer.core.TyperCommand
  • This includes a new auto-generated help text section Arguments for CLI arguments, showing defaults, required arguments, etc.
  • It's also possible to disable it and keep the previous behavior, not showing automatic help for CLI arguments (Click's default) using the hidden parameter.
  • Now show_default is True by default.
  • And now show_envvar is True by default.
  • So, default values and env vars are shown in the help text by default, without having to manually enable them, for both CLI arguments and CLI options.
  • New docs:
    • CLI Arguments Intro.
    • Optional CLI Arguments.
    • CLI Arguments with Default.
    • CLI Arguments with Help.
    • CLI Arguments with Environment Variables.
    • CLI Arguments: Other uses.
    • CLI arguments with tuples.
  • Lot's of tests for all the new examples in the new docs, keeping coverage at 100%.
  • PR #123.
• Add docs for calling packages with python -m some_package using __main__.py: Building a Package: Support python -m. PR #121.
