### forked from [bencode](https://github.com/bittorrent/bencode) to support latest version of python

- extra cython extension to speedup

- ```typing``` with mypy check

### Usage

```python

from pprint import pprint

from bencode import bdecode, bencode

with open("test.torrent", "rb") as f:

    data = f.read()

raw = bdecode(data, decode=False) # do not decode bytes to str, use this to speedup. default is True

pprint(raw)

assert bencode(raw, bufsize=1000000) == data # customize buffer size(in bytes) to speedup, this reduces call to realloc

```

- There are alias function ```loads``` for ```bdecode``` and ```dumps``` for ```bencode```

- ```load``` and ```dump``` are useful for file-like object

```python

from pprint import pprint

from bencode import load, dumps, loads, dumps

with open("test.torrent", "rb") as f:

    data = load(f, decode=False)

pprint(data)

print(dumps(data, bufsize=1000000))

```

### build

git clone https://github.com/synodriver/fast-bencode.git

cd fast-bencode

python setup.py build_ext -i

```
