Protobuf Rules for Bazel

• Postsubmit

This repository contains Starlark implementation of Protobuf rules in Bazel.

For the list of Proto rules, see the Bazel documentation.

Getting Started

To get started with rules_proto, add the following to your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
    name = "rules_proto",
    sha256 = "66bfdf8782796239d3875d37e7de19b1d94301e8972b3cbd2446b332429b4df1",
    strip_prefix = "rules_proto-4.0.0",
    urls = [
        "https://mirror.bazel.build/github.com/bazelbuild/rules_proto/archive/refs/tags/4.0.0.tar.gz",
        "https://github.com/bazelbuild/rules_proto/archive/refs/tags/4.0.0.tar.gz",
    ],
)
load("@rules_proto//proto:repositories.bzl", "rules_proto_dependencies", "rules_proto_toolchains")
rules_proto_dependencies()
rules_proto_toolchains()

Then, in your BUILD files, import and use the rules:

load("@rules_proto//proto:defs.bzl", "proto_library")

proto_library(
    ...
)

If you're migrating from the native proto rules to rules_proto, you can use the following buildifier command to automate the changes to your BUILD and .bzl files:

buildifier --lint=fix --warnings=native-proto <path/to/BUILD>
