bencode2 0.3.0

A fast and correct bencode serialize/deserialize library

A fast and correct bencode serialize/deserialize library

introduction

Why yet another bencode package in python?

because I need a bencode library:

1. Correct, which mean it should fully validate its inputs, and won't try to decode bencode bytes to str by default. Bencode doesn't have a utf-8 str type, only bytes, so many decoder try to decode bytes to str and fallback to bytes, this package won't, it parse bencode bytes value as python bytes.
2. Fast enough, that's why this package is written with c++.
3. even cross implement, what's why this package sill have a pure python fallback and bencode2-${version}-py3-none-any.whl wheel on pypi.

install

pip install bencode2

basic usage

import bencode2

assert bencode2.bdecode(b"d4:spaml1:a1:bee") == {b"spam": [b"a", b"b"]}

assert bencode2.bencode({'hello': 'world'}) == b'd5:hello5:worlde'

Decoding

bencode have 4 native types, integer, string, array and directory.

This package will decode integer to int, array to list and directory to dict.

Because bencode string is not defined as utf-8 string, and will contain raw bytes bencode2 will decode bencode string to python bytes.

Encoding

Many python types are supported.

python type	bencode type
bool	integer 0/1
int, enum.IntEnum	integer
str, enum.StrEnum	string
bytes, bytearray,memoryview	string
list, tuple, NamedTuple	array
dict, OrderedDict	directory
types.MaapingProxy	directory
dataclasses	directory
