config-lang-serder 0.1.1

A Rust library and Python extension for reading and converting configuration files (TOML, YAML, JSON, XML) into Python dictionaries or vice versa. Powered by PyO3.

config_lang_serder

A Rust library and Python extension for reading and converting configuration files (TOML, YAML, JSON, XML) into Python dictionaries and vice versa. Powered by PyO3, this project enables seamless integration of Rust's performance with Python's usability for configuration management.

Features

• Read and parse TOML, YAML, JSON, and XML (not fully supported yet) files
• Unified API: Returns configuration as a Python dict regardless of format
• High performance: Leverages Rust for fast parsing
• Python bindings: Easily callable from Python via PyO3
• Write Python dict to TOML, YAML, or JSON file

Installation

by PyPI

uv pip install config-lang-serder
# or
pip install config-lang-serder

from source (via maturin or setuptools-rust)

Build and install with maturin:

maturin develop

Or build a wheel:

maturin build
pip install target/wheels/config_lang_serder-*.whl

Usage

Python

import config_lang_serder

# Read: Automatically detects file type by extension
config = config_lang_serder.read('config.yaml')
print(config)

# Write: Automatically detects file type by extension
config_lang_serder.write({'foo': 123, 'bar': True}, 'config.yaml')

Current supported extensions: .toml, .yaml, .json, .xml (read), .toml, .yaml, .json (write)

API

• read(path: str) -> dict: Reads a config file and returns its contents as a Python dict. Supported extensions: toml, yaml, json, xml.
• write(dict: dict, path: str) -> None: Writes a Python dict to a file. The format is determined by the file extension (supports: toml, yaml, json).

Development

• Rust code in src/
• Python bindings via PyO3
• Tests in test.py and tests/
