proto-lens-jsonpb

Quick hack to generate orphan ToJSON/FromJSON instances for proto-lens.

This requires the use of proto-lens to generate haskell datatypes from proto messages.

Requirements

1. Install protoc (e.g., brew install protoc)
2. Install the required protoc plugins:
   • cabal install proto-lens-protoc
   • go install github.com/tclem/proto-lens-jsonpb/protoc-gen-jsonpb_haskell

Usage

Use the protoc plugin to generate associated protobuf types from a proto file.

protoc -I=. --proto_path=./proto \
  --plugin=protoc-gen-haskell=`which proto-lens-protoc` --haskell_out=./app \
  --plugin=protoc-gen-jsonpb_haskell=./script/run-jsonpb_haskell --jsonpb_haskell_out=./app \
