Adds Mole for macOS on Apple Silicon and Intel:

[tools]
mole = "latest"

Installs the upstream shell scripts and prebuilt helpers through the GitHub backend, exposing mo and mole. Updates use mise upgrade mole; no Homebrew or Go compiler is required. Supports Mole 1.16.1 and later, when both helper bundles became available. A small postinstall hook places the helpers and preserves the entrypoints’ relative library paths.

Stacked on #13359. This branch includes the URL-template fix, so the entry works with its own backend. Merge #13359 first, then rebase this PR to remove the prerequisite commit. Release the entry with a mise version containing that fix. Users opting into registry_floating on older mise versions must update mise before installing Mole; floating registries do not provide backward compatibility with every older client, as documented.

The daemon e2e test also reuses its already-selected project config instead of searching again after nested project fixtures have been created. This removes one line and fixes the unrelated CI failure introduced on main.

Validation

  • mise ls-remote mole lists versions.
  • mise test-tool mole and mise test-tool mole@1.16.1 pass on macOS ARM64 using an isolated floating registry.
  • Upgrading 1.16.1 to 1.54.0 works with unchanged mole = "latest" configuration.
  • mo analyze --help and mo status --help pass on 1.54.0.
  • mise lock --platform macos-arm64,macos-x64 resolves both helper archives; Intel execution was not tested.
  • Scoped hk/Taplo formatting and validation pass.
  • mise run test:e2e '^test_daemons$' passes with current main merged locally, including the nested-project fixtures that exposed the CI failure.

Popularity

  • GitHub: 67,716 stars and 2,382 forks.
  • Latest release: V1.54.0, September 13, 2026; repository active September 17, 2026.
  • Distributed in Homebrew core.

📝 Walkthrough

Walkthrough

The change adds the Mole tool registry entry, renders templated platform-specific URLs for GitHub, GitLab, and Forgejo, updates backend documentation, adds end-to-end coverage, and removes a duplicate daemon test assignment.

The platform URL test can fail on x86_64 CI despite correct linux-arm64 behavior. Make the expected archive target-specific before merging.

RetriggerConfidence Score: 5/5

The PR appears safe to merge; both previous findings are fixed and the latest change introduces no actionable issue.

Summary

Adds Mole to the registry for macOS Apple Silicon and Intel, with support for Mole 1.16.1 and later.

  • Combines upstream shell scripts with prebuilt helpers and exposes mo and mole.
  • Includes the prerequisite resolved-version URL rendering for the shared GitHub, GitLab, and Forgejo backend, plus documentation and regression coverage.
  • The latest revision removes a redundant daemon-test configuration lookup without changing which file the assertions inspect.

Build the expected URL from the tested target.

The loop resolves arch() for the explicit linux-arm64 target. This expectation instead reads PlatformTarget::from_current(). On an x86_64 runner, the test expects tool-x86_64.tar.gz, but the implementation returns tool-aarch64.tar.gz.

Use the linux-arm64 target when computing conditional_url, or set the expected value to aarch64.

Proposed fix
-            let conditional_url = format!(
-                "https://example.com/2026.09-preview/tool-{}.tar.gz",
-                if PlatformTarget::from_current().arch_name() == "arm64" {
-                    "aarch64"
-                } else {
-                    "x86_64"
-                }
-            );
+            let conditional_url =
+                "https://example.com/2026.09-preview/tool-aarch64.tar.gz".to_string();

The previous Linux e2e failure also occurred on upstream main at 89173bf:

Both fail cli/test_daemons when the assertion for MISE_DAEMON_TASK reads a nested project’s generated pitchfork.toml. After the daemon-group fixtures create several project directories, find "$MISE_STATE_DIR/daemons" -name pitchfork.toml -print -quit can select another project’s file. The test could retain the root project’s generated path selected before those fixtures rather than searching again for the first file.

Fixed in 6991960 by removing the redundant search and retaining the already-selected project config. All assertions remain intact. mise run test:e2e '^test_daemons$' passes with current main merged locally, including the nested-project fixtures. The new CI run now passes completely, including the Linux daemon tests and macOS checks.
