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 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 args to pass directly to protoc, not as plugin options

cpp_grpc_compile

Generates C++ protobuf and gRPC .h & .cc files
