v0.4.0

Using Bzlmod with Bazel 6 or later

1. (Bazel 6 only) Enable with common --enable_bzlmod in .bazelrc.
2. Add to your MODULE.bazel file:

bazel_dep(name = "toolchains_protoc", version = "0.4.0")

# Optional: choose a version of protoc rather than the latest.
protoc = use_extension("@toolchains_protoc//protoc:extensions.bzl", "protoc")
protoc.toolchain(
    # Creates a repository to satisfy well-known-types dependencies such as
    # deps=["@com_google_protobuf//:any_proto"]
    google_protobuf = "com_google_protobuf",
    # Pin to any version of protoc
    version = "v26.0",
)
use_repo(protoc, "com_google_protobuf", "toolchains_protoc_hub")

register_toolchains("@toolchains_protoc_hub//:all")

Using WORKSPACE

Paste this snippet into your WORKSPACE.bazel file:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
    name = "toolchains_protoc",
    sha256 = "270ff656a305e8e2fef22628a13b948554f80c69f53b47dfa7bf09cd99743062",
    strip_prefix = "toolchains_protoc-0.4.0",
    url = "https://github.com/aspect-build/toolchains_protoc/releases/download/v0.4.0/toolchains_protoc-v0.4.0.tar.gz",
)
