Migrate to Bzlmod and add tool_target parameter for CLI tools#20
Conversation
Move all repository rule invocations from WORKSPACE to MODULE.bazel using use_repo_rule (bzlmod-native). Remove --enable_workspace from .bazelrc since Bazel 8 defaults to bzlmod. Add optional tool_target attribute to all cloud rules (s3, gs, minio, b2) so users can point to a Bazel-managed CLI binary (e.g. @my_awscli//:aws) instead of requiring tools on $PATH. When unset, the existing $PATH lookup via repo_ctx.which() is preserved. Add .bcr/ templates (metadata, presubmit, source) for future Bazel Central Registry submission. Partially addresses PR #11. https://claude.ai/code/session_01AxVsJ3PcLBCmcUXAaLKZQk
Replace the per-rule-only tool_target approach with a module extension
(cloud_archive.configure) that lets consumers register CLI tool labels
once in their MODULE.bazel. All cloud_archive rules then automatically
use the configured binaries.
Resolution order: per-rule tool_target > module extension config > $PATH.
Example consumer usage:
cloud_archive = use_extension("@cloud_archive//:extensions.bzl", "cloud_archive")
cloud_archive.configure(s3 = "@my_awscli//:aws")
use_repo(cloud_archive, "cloud_archive_tools")

Covers module extension setup, repository rule declaration, BUILD file consumption, attribute reference, and tool resolution. https://claude.ai/code/session_01AxVsJ3PcLBCmcUXAaLKZQk
Under bzlmod, repos registered via use_repo_rule get canonical names like _main~_repo_rules~<name> in the runfiles tree. Add an _rlocation helper that checks both the bare name and the bzlmod canonical name, as well as the runfiles manifest when available. https://claude.ai/code/session_01AxVsJ3PcLBCmcUXAaLKZQk
Replace the hand-rolled _rlocation helper with Bazel's official runfiles.bash library, which reads the _repo_mapping file and correctly translates apparent repo names to canonical names under bzlmod. Add the @bazel_tools//tools/bash/runfiles dep to the test. https://claude.ai/code/session_01AxVsJ3PcLBCmcUXAaLKZQk

Summary
This PR migrates the cloud_archive project from WORKSPACE-based dependency management to Bzlmod (MODULE.bazel), and adds support for specifying custom CLI tool binaries via a new
tool_targetparameter across all repository rules.Key Changes
Bzlmod Migration: Moved all repository rule definitions from
WORKSPACEtoMODULE.bazel, enabling the project to work with Bazel's modern module system--enable_workspaceflag from.bazelrcas it's no longer neededWORKSPACEfile minimal with just the workspace name declarationTool Target Parameter: Added optional
tool_targetattribute to all cloud provider rules (s3_archive,s3_file,gs_archive,gs_file,minio_archive,minio_file,b2_archive,b2_file)@my_awscli//:aws) instead of relying on tools in$PATH$PATHlookup if not specifiedRefactored Tool Resolution: Extracted tool resolution logic into
_resolve_tool()helper functionBCR Configuration: Added Bazel Central Registry metadata files for publishing
.bcr/metadata.template.json: Module metadata with homepage and maintainer info.bcr/presubmit.yml: CI configuration for verifying builds on Ubuntu and macOS.bcr/source.template.json: Source distribution configurationBuild Configuration: Updated
.gitignoreto trackMODULE.bazel.lockImplementation Details
The
_resolve_tool()function provides a unified interface for tool resolution:tool_targetis provided, it resolves the label to a path (triggering repository fetch)_PROVIDER_TOOL_NAMESmapping and searches$PATHAll cloud download functions now accept and pass through the
tool_targetparameter to enable this functionality.
