Protobuf documantation:

https://protobuf.dev/programming-guides/proto3/

How to set-up

• Download protobuf prebuilt compiler from https://github.com/protocolbuffers/protobuf/releases
• Unzip it to the ./protoc directory
• make sure that ./protoc/bin/protoc is executable
• run ./build_grpc_plugin.sh to enable grpc support (this may take about 10 minutes)

How to use

• add/modify files in ./proto_files directory
• run ./generate.sh
• commit the changes (git add generated/* will be executed automatically)

Direcory structure:

• ./proto_files - the place where all *.proto files should be stored
• ./generated - the protoc keeps generated php/go files here
• ./protoc - the directory where the prebuilt protoc compiler is stored
• ./tools - the directory where the additional tools are stored. Currently only constants2enum.php which converts protobuf generated constants to php 8.x enums
