feat: extract bundled Nushell plugins by default in setup nu

[kiro-agent]

Summary

Changes numan setup nu to extract the full official Nushell release archive (nu + all bundled plugins like polars, query, formats, gstat, inc) instead of filtering to just the nu binary.

Background

PR #101 added an include filter to skip bundled plugins because the 279 MiB uncompressed archive tripped the old 256 MiB bomb cap. The cap was raised to 512 MiB (sufficient), but the include filter remained — leaving a UX gap where users expect the same plugins they'd get from a manual Nushell install.

Changes

• Default full extraction: numan setup nu now extracts everything into tools/nushell/<version>/
• --minimal flag: Escape hatch that restores the old nu-binary-only behavior for users who want lean installs
• Auto-discovery: After extraction, discover_bundled_plugins() scans for nu_plugin_* binaries, computes SHA256, and writes lockfile entries with origin: "bundled:nu"
• List display: numan list shows (bundled with Nu) tag for these entries
• Activate works: Bundled plugins use standard payload_path + executable_path resolution — no changes needed to activate

Collision safety

If a plugin already exists in the lockfile from a registry install (non-bundled origin), the discovery pass skips it rather than overwriting.

Files changed

• src/state/lockfile.rs — BUNDLED_NU_ORIGIN constant
• src/cmd/setup.rs — --minimal flag threading
• src/nu/bootstrap.rs — conditional extract, copy_extracted_files, discover_bundled_plugins
• src/cmd/list.rs — display tag
• src/cmd/nu_pin_offer.rs — constructor update
• tests/setup_nu_test.rs — 5 new integration tests

Verification

• All 908 tests pass (766 lib + 142 integration)
• cargo clippy -- -D warnings clean
• cargo fmt --check clean

Non-blocking follow-ups

• Streaming SHA256 for large plugin binaries (polars ~100MB) to reduce peak memory
• Failure ordering between write_active_version and discover_bundled_plugins

Summary by CodeRabbit

• New Features

  • Added a minimal Nushell installation option that installs only the Nu binary without bundled plugins.
  • Full installations now include bundled Nushell plugins and track them automatically.
  • Package listings identify plugins bundled with Nushell.

• Bug Fixes

  • Prevented removal of bundled Nushell plugins, including with force removal, to protect the shared installation.
  • Added guidance to remove the managed Nushell installation or reinstall in minimal mode.

I've completed a thorough review of PR #133. Here is my analysis.

Review: PR #133 — Extract bundled Nushell plugins by default in setup nu

Verification

• cargo test --lib — 766 passed, 0 failed
• cargo test --test setup_nu_test — 21 passed, 0 failed (3 ignored)
• cargo clippy -- -D warnings — clean
• cargo fmt --check — clean

The feature itself is well-implemented and well-tested: the --minimal flag threading, full-vs-minimal extraction, nu_plugin_*-only copy filter, lockfile discovery with collision-skip semantics, and the (bundled with Nu) list tag all work as described. The test coverage is solid (collision-skip, overwrite-bundled, non-plugin filtering, full-setup-flow lockfile write).

🔴 Blocking — numan remove <bundled-plugin> destroys the entire Nu installation

This is a data-loss bug that should block merge.

Bundled plugin entries set payload_path = "tools/nushell/<version>" — the shared Nu version directory, not a per-plugin directory. But numan remove assumes exclusive ownership of payload_path and calls remove_dir_all on it:

src/cmd/remove.rs:101-167

let payload_path = entry.payload_path().to_string();
let payload_dir = root.join(&payload_path);
...
if payload_dir.exists() {
    std::fs::remove_dir_all(&payload_dir) ...
}

So numan deactivate nushell/polars && numan remove nushell/polars would remove_dir_all(root/tools/nushell/0.114.0) — deleting the nu binary itself and every other bundled plugin in that version. There is no BUNDLED_NU_ORIGIN guard in remove.rs (only origin: None appears in a test fixture).

numan gc is safe — it only scans root/packages/ for orphan candidates (gc.rs:63-72), so it won't touch tools/nushell/. numan update is likely safe (no registry entry to resolve a new version from), but remove is the clear hazard.

Recommended fix: detect origin == BUNDLED_NU_ORIGIN in remove and either (a) refuse with a hint ("bundled plugins are removed with numan setup nu remove"), or (b) delete only the specific executable_path file rather than remove_dir_all on the shared directory. Option (a) is safer and avoids surprising the lockfile/activation-profile bookkeeping for the Nu install.

A test should cover: numan remove nushell/polars on a bundled entry must not delete tools/nushell/<version>/nu.

🟡 Non-blocking observations

1. Short-circuit path skips discovery (bootstrap.rs ~line 1115). The "already installed" branch (options.yes && effective.is_file()) writes the active marker but never calls discover_bundled_plugins. A user who first ran setup nu --minimal then later runs full setup nu on the same version gets neither extraction nor discovery (short-circuit returns early). Consistent (plugins aren't on disk), but there's no minimal→full migration path on an already-installed version. Worth a documented limitation or a "re-extract" force path.

2. Discovery-after-active-marker ordering (acknowledged in the PR body). discover_bundled_plugins runs after write_active_version; a discovery failure leaves the active marker set but no plugin entries, and re-running setup nu short-circuits (no re-discovery). There's no recovery path — consider ordering discovery before the active marker write, or adding a doctor/init --refresh reconciliation hook.

3. doctor reconciliation gap. If discovery fails partway, numan doctor won't detect orphaned nu_plugin_* binaries on disk vs missing lockfile entries. Out of scope here, but worth a follow-up issue so the bundled set is self-healing like the other journals.

4. In-memory SHA256 for large plugins (polars ~100MB). Acknowledged as a follow-up; fine for now.

Minor nits

• copy_extracted_files derives extract_subdir = source.parent().unwrap_or(&extract_root) — unwrap_or silently falls back to scanning extract_root if the binary is at the archive root, which could pick up stray nu_plugin_* files from a differently-shaped archive. Real Nu releases always nest under nu-<version>-<platform>/, so this is theoretical, but a log/warn on the fallback would aid debugging.
• The new list_shows_bundled_with_nu_tag test spawns the real numan binary via CARGO_BIN_EXE_numan; it passes but is heavier than the in-process tests. Acceptable for an integration assertion.

Verdict

The core feature is clean and well-tested, but the shared-payload_path design collides with numan remove's remove_dir_all assumption. I'd ask for the remove-path guard + test before merging.

I've analyzed PR #133 and the review comments. The blocking issue mentioned in the review has already been resolved:

Changes that will be implemented:
None - All valid review feedback has already been addressed in the current code.

Review feedback already implemented:
• Bundled plugin removal guard (src/cmd/remove.rs:58, 93, 196-201) - The ensure_not_bundled_plugin function checks for origin == BUNDLED_NU_ORIGIN and refuses removal with an appropriate error message, preventing destruction of the shared Nu installation directory
• Hint function for bundled plugin removal (src/util/hints.rs:216-223) - The bundled_plugin_remove_gated function provides clear guidance to users about why bundled plugins cannot be removed individually
• Test coverage (src/cmd/remove.rs:314-358) - The execute_refuses_bundled_plugin_without_touching_payload test verifies that removing a bundled plugin is refused and that the shared payload directory (including the nu binary and other bundled plugins) remains intact

The PR already includes all necessary safeguards to prevent the data-loss scenario described in the review. The numan remove command will refuse to remove bundled plugins with a clear error message directing users to use numan setup nu remove instead.

Walkthrough

Changes

The Nushell installer now supports full and minimal extraction. Full installs copy and register bundled plugins with bundled:nu origins. Listing labels these plugins, and removal rejects deleting them independently.

Bundled Nushell plugin support

Layer / File(s)	Summary
Setup options and installation propagation .github/workflows/ci.yml, src/cmd/setup.rs, src/cmd/nu_pin_offer.rs, src/nu/bootstrap.rs, tests/setup_nu_test.rs	Adds the --minimal setup option and propagates it through managed installation APIs. Existing flows use full extraction by default.
Archive extraction and plugin registration src/nu/bootstrap.rs, src/state/lockfile.rs, tests/setup_nu_test.rs	Full installations copy bundled nu_plugin_* files and record hashed bundled:nu lockfile entries. Minimal installations omit plugins and discovery. Tests cover both modes and lockfile updates.
Bundled plugin listing and removal protection src/cmd/list.rs, src/cmd/remove.rs, src/util/hints.rs, tests/setup_nu_test.rs	List output labels bundled plugins. Removal rejects bundled plugins before and after locking, including with --force, and reports shared-payload guidance.

I'll implement the suggested transactional rollback for bundled plugin discovery in Nu setup. Here's what I'll do:

Changes to implement:
• Add rollback logic for discover_bundled_plugins failures in src/nu/bootstrap.rs:1174-1178 - If discovery or lockfile operations fail, remove newly copied bundled binaries before returning the error to prevent orphaned binaries without lockfile entries

The change will ensure that if discover_bundled_plugins fails (due to lockfile load/save errors), the bundled plugin binaries that were copied during full extraction are cleaned up, preventing a state where binaries exist on disk without corresponding lockfile entries.

[amazon-q-developer]

✓ Changes committed successfully.

I've implemented the transactional rollback for bundled plugin discovery. If discover_bundled_plugins fails during Nu setup, all newly copied nu_plugin_* binaries are now removed from the version directory before returning the error. This ensures that no bundled binaries remain exposed without their lockfile entries, preventing orphaned state and allowing setup to be retried cleanly.
