# buf.gen.yaml — protobuf code-generation configuration.
#
# Run with:  make proto-gen
#
# Plugins are resolved from $(LOCALBIN) (./bin/) so no system-wide installation
# is required.  The Makefile targets buf, protoc-gen-go, and protoc-gen-go-grpc
# download and pin exact versions to ./bin/ automatically.
#
# Output is written to gen/go/ using source-relative paths so the on-disk
# directory tree mirrors the proto package hierarchy
# (gen/go/pillar_csi/agent/v1/agent.pb.go).  The go_package option in each
# .proto file controls the Go import path.

inputs:
  - directory: proto

plugins:
  # protoc-gen-go: generates Go struct types and encoding/decoding from .proto.

      - paths=source_relative

  # protoc-gen-go-grpc: generates gRPC client stubs and server interface from
  # service definitions.  require_unimplemented_servers=true (default) makes
  # the compiler reject server structs that omit newly added RPCs, preventing
  # silent API drift.
