pywirehair

A python wrapper for the wirehair forward error correction C/C++ library. wirehair is included as a git subtree.

I'll probably put some wheels in pypi sooner or later. In the meantime:

python setup.py build
python setup.py install

or maybe: pip install https://github.com/sz3/pywirehair/archive/master.zip

Usage

from pywirehair import encoder, decoder

data = b'0123456789' * 10
enc = encoder(data, 40)
a = enc.encode(0)

dec = decoder(len(data), 40)
dec.decode(0, a)

for i in range(2,4):  # skip 1 for fun
    print(i)
    a = enc.encode(i)
    print(dec.decode(i, a))

decoder.decode() will return None if there is more work to do, or the decoded value if all is well. Error cases are not incredibly well handled at the moment, but should explode in predictable and obvious ways.
