========
Overview
========
|pypi-release| |downloads| |tests-status| |coverage| |dev-docs|

**Cloup** — originally from "**Cl**\ick + option gr\ **oup**\s" — enriches
`Click <https://github.com/pallets/click>`_ with several features that make it
more expressive and configurable:

- **option groups** and an (optional) help section for positional arguments

- **constraints**, like ``mutually_exclusive``, that can be applied to option groups
  or to any group of parameters, even *conditionally*

- **subcommand aliases**

- **subcommands sections**, i.e. the possibility of organizing the subcommands of a
  ``Group`` in multiple help sections

- a **themeable HelpFormatter**  that:

  - has more parameters for adjusting widths and spacing, which can be provided
    at the context and command level
  - use a different layout when the terminal width is below a certain threshold
    in order to improve readability

- suggestions like "did you mean <subcommand>?" when you mistype a subcommand.

Moreover, Cloup improves on **IDE support** providing decorators with *detailed*
type hints and adding the static methods ``Context.settings()`` and
``HelpFormatter.settings()`` for creating dictionaries of settings.

Cloup is **statically type-checked** with MyPy in strict mode and extensively **tested**
against multiple versions of Python with nearly 100% coverage.


A simple example
================

.. code-block:: python

    from cloup import (
        HelpFormatter, HelpTheme, Style,
        command, option, option_group
    )
    from cloup.constraints import RequireAtLeast, mutually_exclusive

    # Check the docs for all available arguments of HelpFormatter and HelpTheme.
    formatter_settings = HelpFormatter.settings(
        theme=HelpTheme(
            invoked_command=Style(fg='bright_yellow'),
            heading=Style(fg='bright_white', bold=True),
            constraint=Style(fg='magenta'),
            col1=Style(fg='bright_yellow'),
        )
    )

    # In a multi-command app, you can pass formatter_settings as part
    # of your context_settings so that they are propagated to subcommands.
    @command(formatter_settings=formatter_settings)
    @option_group(
        "Cool options",
        option('--foo', help='This text should describe the option --foo.'),
        option('--bar', help='This text should describe the option --bar.'),
        constraint=mutually_exclusive,
    )
    @option_group(
        "Other cool options",
        "This is the optional description of this option group.",
        option('--pippo', help='This text should describe the option --pippo.'),
        option('--pluto', help='This text should describe the option --pluto.'),
        constraint=RequireAtLeast(1),
    )
    def cmd(**kwargs):
        """This is the command description."""
        pass

    if __name__ == '__main__':
        cmd(prog_name='invoked-command')


.. image:: https://raw.githubusercontent.com/janLuke/cloup/master/docs/_static/basic-example.png
    :alt: Basic example --help screenshot

If you don't provide ``--pippo`` or ``--pluto``:

.. code-block:: text

    Usage: invoked-command [OPTIONS]
    Try 'invoked-command --help' for help.

    Error: at least 1 of the following parameters must be set:
      --pippo
      --pluto

This simple example just scratches the surface. Read more in the documentation
