@hackage protobuf-simple0.1.1.1

An Haskell implementation of Google's Protocol Buffers version 2 with an emphasis on simplicity. The implementation consists of a library for encoding and decoding of data and the `protobuf-simple-protoc` executable for generating Haskell types from proto files. In fact, the types that are used in the tests are generated with the following command:

$ protobuf-simple-protoc data/Types.proto

In the example below, the CustomType is a Haskell type that was generated with the `protobuf-simple-protoc` executable. The encCustomType function encodes a CustomType into a ByteString. The decCustomType function decodes a ByteString into either a CustomType or an error.

module Codec where

import Data.ByteString.Lazy (ByteString)
import Data.ProtoBuf (decode, encode)
import Types.CustomType (CustomType(..))

encCustomType :: CustomType -> ByteString
encCustomType = encode

decCustomType :: ByteString -> Either String CustomType
decCustomType = decode

The library exposes two modules, Data.ProtoBuf, which is used for encoding and decoding and Data.ProtoBufInt, which is an internal module that is used by the generated types.
