Read configuration settings from configuration files.

📚 View Documentation | 🐛 Report a Bug | ✨ Request a Feature

Motivation

When developing a python package, e.g a command-line tool, it can be helpful to allow the user to set their own configuration options to allow them to tailor the tool to their needs. These options are typically set in files in the root of a user's directory that uses the tool, for example in a pyproject.toml or an {project_name}.ini file.

maison aims to provide a simple and flexible way to read and validate those configuration options so that they may be used in the package.

Features

• Supports multiple config files and multiple config filetypes.
• Optional merging of multiple configs.
• Optional config validation with pydantic.
• Caching of config files for quick access.
• Fully tested and typed.

Installation

You can install maison via pip from PyPI:

pip install maison

Installation for Development

To set up maison for local development:

• Clone the repository:

  git clone https://github.com/dbatten/maison.git
  cd maison
  

• Install dependencies using :term:uv:

  uv sync
  

• Install pre-commit hooks:

  uvx nox -s pre-commit -- install
  

This sets up a virtual environment and installs core, development, and quality check dependencies.

Usage

Suppose the following pyproject.toml lives somewhere in a user's directory:

[tool.acme]
enable_useful_option = true

maison exposes a UserConfig class to retrieve values from config files like so:

from maison import UserConfig

from my_useful_package import run_useful_action

config = UserConfig(package_name="acme")

if config.values["enable_useful_option"]:
    run_useful_action()

Development Workflow

This project uses a robust set of tools for development, testing, and quality assurance. All significant automated tasks are run via :term:Nox, orchestrated by the central noxfile.py.

• Run all checks (lint, typecheck, security): uvx nox -s check
• Run test suite with coverage: uvx nox -s test
• Build documentation: uvx nox -s docs
• Build package: uvx nox -s build
• See all available tasks: uvx nox -l

Explore the noxfile.py and the project documentation for detailed information on the automated workflow.
