## 0.6.0

This release adds deep integrations with [Rich](https://rich.readthedocs.io/en/stable/). ✨

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

```console
$ 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](https://rich.readthedocs.io/en/stable/markup.html), and more! 🎉

    * Support for Rich Markup (different from Markdown) in docstrings, *CLI parameters* `help`, and `epilog` with the new parameter `typer.Typer(rich_markup_mode="rich")`, new docs: [Commands - Command Help - Rich Markdown and Markup](https://typer.tiangolo.com/tutorial/commands/help/#rich-markdown-and-markup).

## 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](https://typer.tiangolo.com/tutorial/arguments/).
        * [Optional CLI Arguments](https://typer.tiangolo.com/tutorial/arguments/optional/).
        * [CLI Arguments with Default](https://typer.tiangolo.com/tutorial/arguments/default/).
        * [CLI Arguments with Help](https://typer.tiangolo.com/tutorial/arguments/help/).

        * [CLI Arguments: Other uses](https://typer.tiangolo.com/tutorial/arguments/other-uses/).
        * [CLI arguments with tuples](https://typer.tiangolo.com/tutorial/multiple-values/arguments-with-multiple-values/#cli-arguments-with-tuples).
    * Lot's of tests for all the new examples in the new docs, keeping coverage at 100%.
    * PR [#123](https://github.com/tiangolo/typer/pull/123).
* Add docs for calling packages with `python -m some_package` using `__main__.py`: [Building a Package: Support `python -m`](https://typer.tiangolo.com/tutorial/package/#support-python-m-optional). PR [#121](https://github.com/tiangolo/typer/pull/121).
* Add support for `*args` and `**kwargs` when calling the Typer app, just like in Click. PR [#120](https://github.com/tiangolo/typer/pull/120) by [@teymour-aldridge](https://github.com/teymour-aldridge).

## 0.0.11

* Re-implement completion system:
    * Remove optional dependency `click-completion` (with its sub-dependencies, like Jinja).
    * Add optional dependency `shellingham` to auto detect shell to install (it was used by `click-completion`).
    * Completion now doesn't require a third party library.
        * If `shellingham` is not installed/added as a dependency, `--install-completion` and `--show-completion` take a value with the name of the shell.
    * Fix support for user provided completion in *CLI Parameters*.
    * Fix completion for files in Bash, Zsh, and Fish.
    * Add support for modern versions of PowerShell, 5, 6, and 7 (e.g. in Windows 10).
    * Add support for `pwsh` (PowerShell Core).
        * PowerShell support includes help strings for commands and *CLI Parameters*.
    * Several bug fixes.
    * Tests for the completion logic/code.
    * Tested in all the shells in Linux and Windows.
