About

Helper protoc plugin to clean unused messages from protobuf. Prints out orphan messages and enums that are not used by services.

Sample usage:

protoc --checker_out="." -I . --checker_opt=language_package=java proto/events.proto

Go package is used to resolve file to package mapping. Alternatively you can use java package or proto package by using option langauge_package. E.g.:

protoc --checker_out="." -I . --checker_opt=language_package=java proto/events.proto

Packages can be excluded from with ignore_package param. Messages can be excluded with ignore_message parame:

protoc --checker_out="." -I . --checker_opt=ignore_package=google,ignore_message=foo.Bar proto/events.proto

Check all proto files in directory oneliner:

protoc --checker_out="." -I . $(find . -name "*.proto" |tr '\n' ' ')
