Go

Rules for generating Go protobuf and gRPC .go files and libraries using golang/protobuf. Libraries are created with go_library from rules_go

Rules

Rule	Description
go_proto_compile	Generates Go protobuf .go files
go_grpc_compile	Generates Go protobuf and gRPC .go files
go_proto_library	Generates a Go protobuf library using go_library from rules_go
go_grpc_library	Generates a Go protobuf and gRPC library using go_library from rules_go

go_proto_compile

Generates Go protobuf .go files

Example

Full example project can be found here

BUILD.bazel

load("@rules_proto_grpc_go//:defs.bzl", "go_proto_compile")

go_proto_compile(
    name = "person_go_proto",
    protos = ["@rules_proto_grpc_example_protos//:person_proto"],

Attributes

Attributes for go_proto_compile

Name	Type	Mandatory	Default	Description
protos	label_list	true		List of labels that provide the ProtoInfo provider (such as proto_library from rules_proto)
options	string_list_dict	false	[]	Extra options to pass to plugins, as a dict of plugin label -> list of strings. The key * can be used exclusively to apply to all plugins
verbose	int	false	0	The verbosity level. Supported values and results are 0: Show nothing, 1: Show command, 2: Show command and sandbox after running protoc, 3: Show command and sandbox before and after running protoc, 4. Show env, command, expected outputs and sandbox before and after running protoc
prefix_path	string	false	""	Path to prefix to the generated files in the output directory
extra_protoc_args	string_list	false	[]	A list of extra command line arguments to pass directly to protoc, not as plugin options
extra_protoc_files	label_list	false	[]	List of labels that provide extra files to be available during protoc execution
output_mode	string	false	PREFIXED	The output mode for the target. PREFIXED (the default) will output to a directory named by the target within the current package root, NO_PREFIX will output directly to the current package. Using NO_PREFIX may lead to conflicting writes
