hyperconf 0.2.1

YAML-based configuration library, featuring zero-code validation and parsing.

HyperConfig

Overview

HyperConfig is a Python library for creating schema-based configuration. It allows zero code configuration definition where both the structure and the configuration values are validated using YAML based schema definition files.

Advantages:

• less code: define the structure in YAML, validate and load configs using a one-liner.
• shared schemas: define once, use in multiple projects.
• extensibility: add configuration types and validation rules without coding.

Installation

pip install hyperconfig

Usage

Define your schema in a definition file, ships.yaml:

# Spaceship Configuration Schema

ship_type:
  type: str
  validator: hval.isalpha()
  required: true

shipcolor:
  type: str
  validator: hval.lower() in ['red', 'blue', 'green', 'yellow', 'gray']
  required: true

enginepower:
  type: int
  validator: 100 <= hval <= 1000
  required: true

shieldlevel:
  type: float
  validator:  0.0 <= hval <= 1.0
  required: true

ship:
  captain: str
  crew:
   type: int
   validator: hval > 0
  class: shiptype
  color: shipcolor
  shields: shieldlevel
  engines: enginepower

Then use the schema to create configuration values, gameconfig.yaml:

use: ships

ncc1701=ship:
  captain: James T. Kirk
  crew: 203
  class: constitution
  color: gray
  shields: 1.0
  engines: 900

and load it:

>>> from hyperconfig import HyperConf
>>> config = HyperConf.load("gameconfig.yaml")
>>> print(config.ncc1701.captain)
