## Using Bzlmod with Bazel 6:
1. Enable with \`common --enable_bzlmod\` in \`.bazelrc\`.
2. Add to your \`MODULE.bazel\` file:
\`\`\`starlark
bazel_dep(name = "aspect_bazel_lib", version = "${TAG:1}")
\`\`\`
> Read more about bzlmod: <https://blog.aspect.dev/bzlmod>
## Using WORKSPACE
Paste this snippet into your \`WORKSPACE\` file:
\`\`\`starlark
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
name = "aspect_bazel_lib",
sha256 = "${SHA}",
strip_prefix = "${PREFIX}",
url = "https://github.com/aspect-build/bazel-lib/releases/download/${TAG}/${ARCHIVE}",
)
load("@aspect_bazel_lib//lib:repositories.bzl", "aspect_bazel_lib_dependencies")
aspect_bazel_lib_dependencies()
\`\`\`
Optional toolchains:
\`\`\`starlark
# Register the following toolchain to use jq
load("@aspect_bazel_lib//lib:repositories.bzl", "register_jq_toolchains")
register_jq_toolchains()
# Register the following toolchain to use yq
load("@aspect_bazel_lib//lib:repositories.bzl", "register_yq_toolchains")
register_yq_toolchains()
\`\`\`
