## About The Project
This library allows rapid creation of a CLI by automatically reading the attributes, methods and function parameters inside a class and generating its corresponding Command Line Interface through the built-in argparse library. The module contains an optional output processor able to print the result of the executed command in different formats.
<p align="right">(<a href="#readme-top">back to top</a>)</p>
## Getting Started
The necessary steps to get the library working on your environment.
### Prerequisites
Before using the application you need to have installed [python](https://www.python.org/). You can get instructions on how to install it by following the link shown before.
### Install the library
#### Get the latest version of the library from the github repository
```bash
pip3 install git+https://github.com/AlexSua/python-cli-generator.git
```
#### Get the stable version from the PyPI repository
```bash
pip3 install python-cli-generator
```
<p align="right">(<a href="#readme-top">back to top</a>)</p>
## Usage
### Import the library
Import the controller class "Cli" which contains the main functionality for initializing the generation process.
```Python
from python_cli_generator import Cli
```
### Initialize HTTPSession and CacheStorage (Optional)
Initialize classes HTTPSession and CacheStorage for fetching from a REST API and cache the result of a method into a file respectively. These classes contain a method that acts as a decorator for another method providing extra functionality. You can see the example that follows to see how it works.
```python
from python_cli_generator.plugins.cache import CacheStorageFile
from python_cli_generator.plugins.http import HTTPSession
# Introduce as arguments here all parameters who wish to be passed as attributes to session of the requests library. Every request through the method decorator called fetch from HTTPSession will use this parameters on each request.
jikanmoe = HTTPSession(url_base="https://api.jikan.moe/v4/", headers={
'sec-ch-ua': '"Google Chrome";v="107", "Chromium";v="107", "Not=A?Brand";v="24"',
'sec-ch-ua-mobile': '?0',
'sec-ch-ua-platform': '"Linux"',
'Upgrade-Insecure-Requests': '1',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
})
# Initialize the file where the result of cached methods will be stored.
cache_storage = CacheStorageFile(file_name=".cache.example_filename")
```
### Create input classes
Create the classes the generator will use to generate the Command line interface.
> Notice that comments are as well parsed and automatically added to the CLI.
```Python

## Roadmap
* [x] Added options to disable/enable class attributes arguments generation.
* [x] Support for class with non-empty constructors.
* [x] Support for a list of classes in JSON format.
* [ ] Support for a list of classes with non-empty constructors.
* [x] Support for DateTime with the following formats 2022-12-20/00:00:20 and 2022-12-20
* [x] Support for enumeration type. It will be interpreted as argparse "choices".
* [x] _default method inside a class will be treated as the method that is going to be executed in the specified subparser.
* [ ] Generate a log file with last commands executed.
* [x] Improve performance with argument prediction. Only generate the arguments that the program know that are introduced.
* [ ] Improve documentation
* [ ] Add tests
* [x] Add an argument that supports writing into a file instead of printing in the terminal.
* [ ] Possibility to add custom arguments.
* [ ] Add decorators to change the behavior of the arguments generated.
* [x] Add configuration file. The CLI can fetch/store the configuration for classes introduced as arguments in 'generate_arguments'
* [x] Add cache. A cache decorator can be used to save the result between executions of a function for a given set of arguments during a given time.
* [x] Add REST API support. A REST API decorator can be used to use an API using the python method parameters as input for generating the request.
* [x] Add multiple output support. CSV and YAML.
