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`

Installation#

The Go module can be installed by adding the following lines to your MODULE.bazel file, replacing the version number placeholder with the desired version:

bazel_dep(name = "rules_proto_grpc_go", version = "<version number here>")

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"],
)

go_proto_compile(
    name = "place_go_proto",
    protos = ["@rules_proto_grpc_example_protos//:place_proto"],
)

go_proto_compile(
    name = "thing_go_proto",
    protos = ["@rules_proto_grpc_example_protos//:thing_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
