[Note: this plugin is now developed alongside the library in the pb repository.]

pb-plugin

A protoc plugin that turns .proto files into OCaml protobuf serialization functions built with the pb library.

Use

protoc --plugin=protoc-gen-custom=$(type -p pb_plugin) --custom_out=./build file.proto

Implementation notes

The interface between protoc and plugins is defined as a set of protobuf messages that describe the contents of a .proto file.

The pb-plugin plugin is bootstrapped. The file src/protoc_messages.ml that reads and writes messages passed between protoc and the plugin is generated from the file misc/messages_unnested.proto using pb-plugin itself
