Crate hjkl_anvil 

Mason-style LSP and developer-tool installer.

hjkl-anvil is the tool-installation sibling of hjkl-bonsai. Where bonsai manages tree-sitter grammars, anvil manages language servers, formatters, linters, and debug adapters — using the same XDG path conventions and compile-time embedded catalog pattern.

Features

sync (dev-only)

Enables the sync-anvil xtask binary that regenerates anvil.toml from the upstream mason-org/mason-registry JSON artifact. Not needed by downstream consumers — it pulls in reqwest, zip, and serde_json.

Maintainers run:

cargo run -p hjkl-anvil --features sync --bin sync-anvil -- --pin <tag>

Quick start

use hjkl_anvil::{Registry, ToolCategory};

let registry = Registry::embedded().expect("embedded catalog must load");
println!("catalog has {} tools", registry.len());

if let Some(spec) = registry.get("rust-analyzer") {
    println!("rust-analyzer v{}", spec.version);
}

for name in registry.by_category(ToolCategory::Lsp) {
    println!("  lsp: {name}");
}
