== Description

The `bazel` crawler looks recursively for every `MODULE.bazel` file from a root directory, and updates each `bazel_dep()` declaration it contains.

[source,python]
----
# MODULE.bazel
bazel_dep(name = "rules_go", version = "0.46.0")
bazel_dep(name = "gazelle", version = "0.35.0", dev_dependency = True)
----

Both regular and `dev_dependency` declarations are updated.

This crawler is enabled by default, so it can be used either automatically by running `updatecli diff` from a directory containing the files to update, or by providing a manifest.
The automatic discovery behavior can be tuned by providing a YAML manifest with a `bazel` crawler in top-level directive `autodiscovery` as explained in the link:/docs/core/autodiscovery/#_parameters["Autodiscovery" page].

== Generated manifests

Each dependency produces a link:{{< ref "bazelregistry" >}}[`bazelregistry`] source resolving the latest module version from the Bazel Central Registry, and a link:{{< ref "bazelmod" >}}[`bazelmod`] target writing it back into `MODULE.bazel`.

== Limitations

* Only the module system is covered. Legacy `WORKSPACE` files and their `http_archive` or `git_repository` rules are not scanned.

== Manifest
=== Parameters

{{< autodiscoveryparameters "bazel" >}}
