bson-modern 1.0.0

BSON codec for Python - modernized fork with Python 3.12+ support

bson-modern

A modernized fork of the bson package with Python 3.12+ support.

Why this fork?

The original bson package has not been updated since 2018 and is incompatible with Python 3.12+ due to:

• Use of deprecated pkgutil.find_loader() (removed in Python 3.12)
• Dependency on the six package for Python 2/3 compatibility

This fork removes all Python 2 compatibility code and modernizes the package for Python 3.12+.

Installation

pip install bson-modern

Usage

import bson

# Encode a dictionary to BSON
data = {"name": "Alice", "age": 30, "active": True}
encoded = bson.dumps(data)

# Decode BSON back to dictionary
decoded = bson.loads(encoded)
print(decoded)  # {'name': 'Alice', 'age': 30, 'active': True}

Compatibility with antares-client

This package is designed to be a drop-in replacement for bson when using packages like antares-client that depend on standalone BSON support.

To use with antares-client, install bson-modern before antares-client:

pip install bson-modern antares-client

Or in your pyproject.toml:

dependencies = [
    "bson-modern>=1.0.0",
    "antares-client>=1.3.0",
]

Changes from original bson

• Python 3.12+ only - Dropped Python 2.x and early Python 3.x support
• Removed six dependency - No longer needed for Python 2/3 compatibility
• Modern packaging - Uses pyproject.toml and hatchling
• Fixed build system - No longer uses deprecated pkgutil.find_loader()
