batconf 0.3.0

Application configuration tool from the BAT project

BatConf

Configuration Management for Python projects, modules, applications, and microservices.

Compose structured hierarchical configurations from multiple sources. Enable your code to adapt seemlessly to the current context. Allow users in different contexts to use the config source that works best for them.

• Hierarchical priority: CLI > Environment > config file > module defaults
• Provides builtin support for common config sources:
  • CLI args
  • Environment Variables
  • Config File (yaml)
  • Config classes with default values
• Easily extendable, add new sources to serve your needs.
• Set reasonable defaults, and override them as needed.
• Designed for 12-factor applications (config via Environment Variables)

Users can create their own config sources by creating classes that satisfy batconf.source.SourceInterfaceProto (or subclass batconf.source.SourceInterface)

The config lookup order is determined by the SourceList instance, which can be adjusted to suit your needs.

Design Principles

• Non-Intrusive Integration: BatConf can be seamlessly incorporated into existing projects with minimal code modifications.
  • imports from batconf can be isolated to a single source file
  • Config classes utilize stdlib dataclasses
• Portability and Modularity: Modules (sub-modules or entire projects) that use batconf configuration should be easy to compose and refactor.
  • modules can be easily plugged in to other modules.
  • modules can be easily factored out (into new projects).
