protogen-demo

show how to develop your own proto codegen plugin, you can also read my blog post !

protoc-gen-demo

use google.golang.org/protobuf/compiler/protogen lib to demo how to develop proto codegen plugin

go build -o ./protoc-gen-demo/protoc-gen-demo.bin ./protoc-gen-demo
protoc \
--plugin=protoc-gen-demo=./protoc-gen-demo/protoc-gen-demo.bin \
--go_out=paths=source_relative:. \
--demo_out=foo=bar,paths=source_relative:. \
proto/pb.proto

protoc-gen-demo2

use github.com/lyft/protoc-gen-star lib to demo how to develop proto codegen plugin

go build -o ./protoc-gen-demo/protoc-gen-demo.bin ./protoc-gen-demo
protoc \
--plugin=protoc-gen-demo2=./protoc-gen-demo2/protoc-gen-demo2.bin \
--go_out=paths=source_relative:. \
--demo2_out=foo=bar,paths=source_relative:. \
proto/pb.proto

protoc-gen-debug

show how to debug your own plugin

1.  protoc \                                                                                 
    --plugin=protoc-gen-debug=./protoc-gen-debug/protoc-gen-debug.bin \
    --go_out=paths=source_relative:. \
    --debug_out=.:. \                    
    proto/pb.proto
   

2. and run go run main.go in protogen-demo folder`
