benparse

benparse is a bencode parser for Python 3. It is capable of reading and creating bencoded files such as torrents

Features

• Syntax is similar to built-in modules such as json and pickle
• Has an optional strict mode that will raise an error when it encounters non-fatal errors such as out-of-order dict keys or integers with leading zeros. This ensures that "round-tripping" bencoded data (loading bencoded data and then dumping it back to bencode) will never caused unexpected changes
• Able to change the character encoding used to encode/decode strings
• Fully typed

Usage

Complete usage documentation and examples are available here

# Load a bencoded file
with open('linux_distro.torrent', 'rb') as file:
    torrent_dict = benparse.load(file)

# Make changes
torrent_dict[b'announce'] = b'http://mirror.example.org:6969/announce'

# Save a Python object as a bencoded file
with open('linux_distro.torrent', 'wb') as file:
    benparse.dump(torrent_dict, file)

Requirements

• Python 3.6+
• Typing Extensions (only for Python versions less than 3.8)

Installation

Install from PyPI:

pip3 install benparse

Install from source:

git clone https://gitlab.com/adralioh/benparse.git
pip3 install ./benparse

Tests

Tests are run using the built-in unittest module, and Coverage.py is used to measure code coverage

Run tests without measuring coverage:

python3 -m unittest discover tests

Run tests and measure coverage:

coverage run -m unittest discover tests

View the results:

coverage report

Generate a detailed report, outputted to ./htmlcov:

coverage html
