A Configuration management system for Python projects.

# VR.Hercules

VR.Hercules is a configuration management system for Python projects. Assuming your configuration to use YAML configuration files, you can define their structure and type by Python schema files. That way, this project enables easy configuration with minimal syntax while providing software assistance for using configurations.

## Features

• Python-based typed schema definition
• Autocompletion within IDEs
• Semi-automatic parsing of yaml files
• Extensibility for custom types
• Reconfiguration at runtime

## Problem Statement

Oftentimes, we build systems from configurable parts. Ideally, the configuration would be structured like our system. Therefore, we need a structuring configuration system.

## Approach

The de-facto standard configuration language is currently YAML. The structure with the least syntax in Python are classes. So, we choose YAML as configuration syntax and Python classes as parsing target.

## Mental Model

As shown on the left, a composed systems without a configuration management system might end up with different means of configuration. As shown on the right, a composed system using this package can use a single means of configuration for all its components. This helps with increasing development velocity because all components benefit from the features of the configuration management system.

## Status

This package is not licensed. Therefore, it can only be used in the DFKI.

## Usage

This package originates from and is being used in production at the VR.Backend project. However, the VR.Backend project is currently internal to the DFKI.

## Demo

This package enables parsing configuration files according to a schema:

class Config:
greeting: str
greetee: str

Config: type = parse_config(
config_file_path='config.yaml',
)
