This morning I was looking for a Go implementation of rencode, the Web safe object pickling/unpickling library originally written in Python (original implementation by C. Barnes can be read here: http://www.connellybarnes.com/code/python/rencode).
It is basically a simplified bencode implementation, that shortcuts a few bytes on small numbers and small lists/dictionaries.
It can be useful for example to communicate as a Go native client with Twisted RPC servers, and although you could also write a compatible server with it I would suggest to use JSON/RPC or gob/gRPC these days for a modern RPC server.
Since I found no existing Go implementation of rencode, I wrote a Go one based on Andrew Resch’ Cython implementation.
Here it is, complete with godoc documentation:
