How to specify "binary=True" in go_repo like in go_module

[linuxerwang]

go_module supports a "binary=True" which builds an executable, but go_repo doesn't have this parameter, what's the correct way to do it?

go_module(
    name = "protoc-gen-go",
    binary = True,
    install = ["protoc-gen-go"],
    module = "github.com/golang/protobuf",
    ...
)

Thanks!

Assuming protobuf is defined in third_party/go/BUILD as follows:

## third_party/go/BUILD

go_repo(
    name = "google.golang.org_protobuf",
    module = "google.golang.org/protobuf",
    # ...
)

go_repo defines a subrepo, so the binary is already a distinct target in the build graph - the target's name is based on the structure of the Go module, so protoc-gen-go would be ///third_party/go/google.golang.org_protobuf//cmd/protoc-gen-go.
