**click-option-group** is a Click-extension package that adds option groups 
missing in [Click](https://github.com/pallets/click/).

## Aim and Motivation

Click is a package for creating powerful and beautiful command line interfaces (CLI) in Python, 
but it has no the functionality for creating option groups.

Option groups are convenient mechanism for logical structuring CLI, also it allows you to set 
the specific behavior and set the relationship among grouped options (mutually exclusive options for example). 
Moreover, [argparse](https://docs.python.org/3/library/argparse.html) stdlib package contains this 
functionality out of the box.

At the same time, many Click users need this functionality.
You can read interesting discussions about it in the following issues:

* [issue 257](https://github.com/pallets/click/issues/257)
* [issue 373](https://github.com/pallets/click/issues/373)
* [issue 509](https://github.com/pallets/click/issues/509)
* [issue 1137](https://github.com/pallets/click/issues/1137)

The aim of this package is to provide group options with extensible functionality 
using canonical and clean API (Click-like API as far as possible).

## Quickstart

### Installing 

Install and update using pip:

```bash
pip install -U click-option-group
```

### A Simple Example

Here is a simple example how to use option groups in your Click-based CLI.
Just use `optgroup` for declaring option groups by decorating 
your command function in Click-like API style.

```python
# app.py

import click
from click_option_group import optgroup, RequiredMutuallyExclusiveOptionGroup

@click.command()
@optgroup.group('Server configuration', 
                help='The configuration of some server connection')
@optgroup.option('-h', '--host', default='localhost', help='Server host name')
@optgroup.option('-p', '--port', type=int, default=8888, help='Server port')
@optgroup.option('-n', '--attempts', type=int, default=3, help='The number of connection attempts')
@optgroup.option('-t', '--timeout', type=int, default=30, help='The server response timeout')
@optgroup.group('Input data sources', cls=RequiredMutuallyExclusiveOptionGroup, 
                help='The sources of the input data')
@optgroup.option('--tsv-file', type=click.File(), help='CSV/TSV input data file')
@optgroup.option('--json-file', type=click.File(), help='JSON input data file')
@click.option('--debug/--no-debug', default=False, help='Debug flag')
def cli(**params):
    print(params)

if __name__ == '__main__':
    cli()
```

```bash
$ python app.py --help
Usage: app.py [OPTIONS]

Options:
  Server configuration:           The configuration of some server connection
    -h, --host TEXT               Server host name
    -p, --port INTEGER            Server port
    -n, --attempts INTEGER        The number of connection attempts
    -t, --timeout INTEGER         The server response timeout
  Input data sources: [mutually_exclusive, required]
                                  The sources of the input data
    --tsv-file FILENAME           CSV/TSV input data file
    --json-file FILENAME          JSON input data file
  --debug / --no-debug            Debug flag
  --help                          Show this message and exit.
```
