Summary

  • add state = "absent" to declarative bootstrap package entries
  • plan, report, and apply exact non-cascading removals through pacman
  • keep mise packages use intuitive by changing an absent entry back to present
  • document compatibility with packages installed from configured third-party pacman repositories, including OPR

Testing

  • mise run lint-fix
  • mise run build
  • MBX_DISABLE=1 mise exec -- cargo test --all-features --no-run
  • MBX_DISABLE=1 mise exec -- cargo test --all-features absent
  • MBX_DISABLE=1 mise exec -- cargo test --all-features test_remove_args_remove_exact_packages_without_cascading
  • MBX_DISABLE=1 mise exec -- cargo test --all-features test_update_bootstrap_package_preserves_options
  • manually exercised status, plan, and dry-run apply against a fake pacman executable

Notes

OPR packages require no special removal path: once installed, pacman exposes them through the same local package database as official repository packages.

The Cargo test compile passed with MBX_DISABLE=1 after the transparent wrapper encountered missing cache blobs; the ordinary wrapped project build and lint checks passed.

AI-assisted — Tool: Codex; model: unavailable; version: unavailable.


Note

Medium Risk
Apply can uninstall system packages via pacman (sudo), and status/doctor semantics changed for absent entries; scope is limited to pacman removal support today.

Overview
Adds state = "absent" on [bootstrap.packages] table entries so a more local config can override a global pacman package and request removal. mise bootstrap packages apply now uninstalls those packages (with prompts/dry-run) via pacman -R --noconfirm, without cascading to dependents; other built-in managers still only support present and error if removal is requested.

Status, bootstrap plan JSON, and --missing treat desired_state: absent-and-not-installed is converged, but still-installed packages are drift (unexpectedly installed). Doctor, install throttling, and missing counts ignore absent entries. mise bootstrap packages use flips an absent entry back to present when you pin a version.

Pacman status/removal resolves virtual Provides using parsed pacman -Qi metadata (replacing per-name pacman -Q for providers). bootstrap packages apply is classified destructive in usage/docs because it can remove packages.

Changes

Declarative package removal

Layer / File(s) Summary
Request state and configuration contract
src/system/mod.rs, src/system/packages/*, src/config/config_file/mise_toml.rs, src/system/deps.rs, src/oci/packages.rs
Package requests and TOML options support Present and Absent. Existing request builders set Present. Updating an absent package rewrites it as present.
Removal capability and resource planning
src/system/packages/mod.rs, src/system/packages/pacman.rs, src/system/resources.rs
Managers expose removal capability. Pacman resolves concrete installed names. Resource planning creates removal, no-op, or unknown actions.
Apply-time removal execution
src/cli/system/driver.rs, src/cli/command_effects.rs, mise.usage.kdl, docs/cli/bootstrap/packages/apply.md
The install driver handles absent targets, validates removal support, confirms removal, and executes it. The apply command is destructive.
Status and diagnostic reporting
src/cli/bootstrap.rs, src/cli/system/status.rs, src/cli/doctor/mod.rs, src/cli/install.rs, e2e/cli/test_system_status
Reports classify absent packages correctly, include desired_state, and exclude absent requests from present-package missing counts.
Package configuration documentation
docs/bootstrap/packages/index.md, docs/bootstrap/packages/pacman.md
Documentation describes absent pacman entries and removal behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 4b865

Absent pacman declarations can trigger privileged package removal, but an ambiguous virtual package name may cause the wrong installed provider to be removed or require repeated applies. Merge should wait for an explicit ambiguity rule, and the command documentation should clearly warn that absent entries can uninstall packages.

Greptile Summary

The PR adds declarative absent-state package handling and pacman removal support while updating status output, configuration mutation, command-effect metadata, documentation, and tests.

  • Resolves virtual pacman requirements through installed package metadata.
  • Applies absent declarations through exact, non-cascading pacman -R invocations.
  • Marks package apply as destructive and reports desired state in status output.

Confidence Score: 4/5

The PR is not yet safe to merge because an absent virtual pacman capability can remove additional installed provider packages.

Status selects one provider for a virtual package, but the removal path independently collects every installed package matching that capability and passes all of them to pacman, leaving the previously reported over-removal defect outstanding.

Files Needing Attention: src/system/packages/pacman.rs

Important Files Changed

Filename Overview
src/system/packages/pacman.rs Adds installed-metadata parsing and concrete removal resolution, but the previously reported multi-provider over-removal remains.
src/cli/system/driver.rs Separates present installation targets from absent removal targets and routes removals through manager support checks and confirmation handling.
src/cli/command_effects.rs Correctly reclassifies bootstrap package apply as destructive and adds a matching assertion.
src/system/mod.rs Adds present/absent configuration parsing and propagates desired state into package requests.
src/config/config_file/mise_toml.rs Makes package-use updates reset absent declarations to present while preserving existing package options.
src/cli/system/status.rs Reports desired state and treats installed absent packages as drift.
