Maison

Read configuration settings from configuration files.

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 project 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

pip install maison

Usage

Suppose the following pyproject.toml lives somewhere in a project directory:

[tool.acme]
enable_useful_option = true

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

from maison import ProjectConfig

from my_useful_package import run_useful_action

config = ProjectConfig(project_name="acme")

if config.get_option("enable_useful_option"):
    run_useful_action()
