# The `clinterfacer` framework
[](https://gitlab.com/adrianohrl/clinterfacer/-/commits/master)
[](https://pypi.org/project/clinterfacer/#history)
This framework aims to simplify the creation of Command-Line Interfaces (CLIs) using python.
## Installation
To install the `clinterfacer` framework using [pip](https://pip.pypa.io/en/stable/) only, enter the following command:
```bash
pip install clinterfacer==1.3.0
```
However, if you are using [`pipenv`](https://pipenv.kennethreitz.org), enter the following command in the root of your project.
```bash
pipenv install clinterfacer==1.3.0
```
## Usage
After installation, it must be exist the follow files and folders in your project:
```bash
clinterfaced
├── clinterfaced*
│ ├── commands*
│ │ ├── build.py
│ │ ├── config.py
│ │ ├── deploy.py
│ │ ├── doc.py
│ │ ├── get_param.py
│ │ ├── __init__.py*
│ │ └── train.py
│ ├── __init__.py*
│ ├── __main__.py*
│ ├── resources**
│ │ ├── __init__.py**
│ │ └── logging.ini**
│ ├── subparsers*
│ │ ├── build.py
│ │ ├── config.py
│ │ ├── deploy.py
│ │ ├── doc.py
│ │ ├── get_param.py
│ │ ├── __init__.py*
│ │ └── train.py
│ └── utils.py
├── Makefile
├── Pipfile
├── README.md*
└── setup.py*
```
All the above files and folders ending with `*` are expected by the `clinterfacer` framework. However, all the above files and folders ending with `**` are opitional and are used by the `clinterfacer` framework to load the desired logging configuration. The remaining files and folders were merely used for exemplifying.
### The `setup.py` file
There is a template for the `setup.py` file bellow.
```python
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""This file is used to install the clinterfaced package."""
# standard library(ies)
import pathlib as pl
import typing
# 3rd party package(s)

def read(path: typing.Union[str, pl.Path], encoding: str = 'utf-8') -> str:
if isinstance(path, str):
path = pl.Path(path)
return path.read_text(encoding) if path.exists() else ''
readme = pathlib.Path('./README.md')
metadata = {

}
if __name __ == '__main__':
setuptools.setup(**metadata)
```
### The `__init__.py` file
```python
#!/usr/bin/env python
"""__init__.py: This script includes all the project's metadata."""
__authors__ = (
'Adriano Henrique Rossette Leite',
)
__email__ = (

### The `__main__.py` file
```python
#!/usr/bin/env python
"""This is the main script of the clinterfaced package."""
# standard library(ies)
import sys
# 3rd party package(s)
import clinterfacer
def main() -> int:
cli = clinterfacer.CLI()
return cli.main()
if __name__ == '__main__':
return sys.exit(main())
```
### The `commands` folder
The script below is an example of the implementation of a command named as `get-param`.
```python
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""This is the main script of the clinterfaced's get-param command."""
# standard library(ies)
import argparse
import logging
import sys
# local source(s)
from clinterfaced.subparsers.get_param import parse_args
logger = logging.getLogger(__name__)
parameters = {
'framework': 'CLInterfacer',
}
def main(args: argparse.Namespace) -> None:
logger.info(f'Getting parameter the clinterfaced\'s {args.parameter} paramenter ...')
logger.info(f'Value for the {args.parameter} parameter: \'{parameters[args.parameter]}\'')
if __name__ == '__main__':
args = parse_args()
sys.exit(main(args))
```
### The `subparsers` folder
The script below is an example of the definition of the arguments of a command named as `get-param`.
```python
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""This script defines the clinterfaced's get-param subparser."""
# standard library(ies)
import argparse
# 3rd party package(s)
from clinterfacer import cli
def add_parser(subparsers: argparse._SubParsersAction) -> None:
parser = subparsers.add_parser(
'get-param',
help='This is the get-param command of the clinterfaced package',
prog='clinterfaced get-param',
description='This command is the get-param one.',
)
add_arguments(parser)
def add_arguments(parser: argparse.ArgumentParser) -> None:
parser.add_argument(
'parameter',
help='Specifies the name of the desired paramenter.',
metavar='PARAMETER',
)
def parse_args() -> argparse.Namespace:
parser = argparse.ArgumentParser()
add_arguments(parser)
args = parser.parse_args()
cli.setup()
return args
```
### Installing the package
```bash
pipenv install clinterfacer
```
### Entering the commands in terminal
```bash
pipenv shell
