This repository contains an example of a protoc plugin written in C++.

This example plugin generates text files that list the messages defined in proto files.

To build the plugin you will need to have a compiler (such as clang++) locally installed.

1. Install Google Protobuf from source by following the instructions here.

   You should know the locations where header files, libprotoc and libprotobuf got installed.

2. Clone this repository:

git clone http://github.com/thesamet/protoc-plugin-in-cpp

cd protoc-plugin-in-cpp

3. Build the plugin

clang++ my_protoc_plugin.cc -o my_protoc_plugin  -lprotoc -lprotobuf

(pass -I and -L as necessary to point at the external include files and libraries)

4. Try it out!

protoc --plugin=protoc-gen-example=my_protoc_plugin  \              
       protos/a.proto protos/b.proto -I protos \
       --example_out=protos
