A multiaddr implementation in Haskell. Multiaddr is a self-describing network address format supporting a variety of protocols, with both string and binary representations.
We're on Hackage, so just add
multiaddr to your cabal build-depends.
import Network.Multiaddr let Just somewhere = readMultiaddr "/ip4/184.108.40.206/tcp/80" protocolNames somewhere -- ["ip4", "tcp"] -- Encapsulation -- Multiaddr is a monoid, `encapsulate` is just an alias for (<>) let Just proxy = readMultiaddr "/ip6/::1/tcp/443" let proxied = proxy `encapsulate` somewhere toText proxied -- "/ip6/::1/tcp/443/ip4/220.127.116.11/tcp/80" hasIPv6 proxied -- True -- Grab an individual part of the address parts proxied !! 2 -- "/ip4/18.104.22.168" -- Encode into a ByteString let bytes = encode proxied -- Decode and get back the original! let Just decoded = decode bytes decoded == proxied -- True
