hjkl-anvil

Mason-style LSP and developer-tool installer

Part of the hjkl monorepo — a vim-modal editor in Rust.

Overview

hjkl-anvil provides a self-contained tool-installation pipeline compatible with mason-org/mason-registry manifests. It supports GitHub release tarballs/zips, cargo install, npm install, pip install, and go install backends with SHA-256 verification, atomic rename + symlink finalization, and a .rev sidecar for version tracking.

Modules

• manifest — parse and validate anvil.toml manifests (Manifest, ToolSpec, InstallMethod, ManifestError).
• registry — in-process tool registry backed by the embedded anvil.toml (Registry, RegistryError).
• store — XDG-aware path layout helpers and atomic rev sidecar read/write (RevSidecar, data_root, packages_dir, bin_dir, …).
• installer — Install trait, per-backend pipelines, install_blocking dispatcher, path-traversal guard (safe_join), InstallStatus enum.
• job — InstallPool (2-thread), InstallHandle, per-key deduplication.
