bencode-foo

a minimal bencode decoder written in go.

this project exists mainly to understand how bencoding works internally (strings, ints, lists, dicts) using a manual cursor + recursive parsing.

just learning + experimentation (as part of learning working of bittorrent internals)

• binary-safe (strings are returned as []byte)
• recursive descent parser
• minimal main.go for quick testing
