This framework aims to simplify the creation of Command-Line Interfaces (CLIs) using python.

cli

This framework aims to simplify the creation of Command-Line Interfaces (CLIs) using python.

Installation

To install the clinterfacer framework using pip only, enter the following command:

pip install clinterfacer==1.1.7

However, if you are using pipenv, enter the following command in the root of your project.

pipenv install clinterfacer==1.1.7

Usage

After installation, it must be exist the follow files and folders in your project:

clinterfaced
├── clinterfaced*
│   ├── commands*
│   │   ├── build.py
│   │   ├── config.py
│   │   ├── deploy.py
│   │   ├── doc.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.
