Detect the kind of a project (Rust, Node, Bun, Deno, Python, Lua, C, C++) from on-disk signals (Cargo.toml, package.json, etc.) and scan a polyglot monorepo workspace recursively.

The crate is dependency-light and free of opinions about builds: it only answers "what is in this directory?" and "what projects live under this root?".

Quick start

use std::path::Path;
use standarbuild_detect::{detect_in_dir, discover, DiscoverOptions, ProjectKind};

let (kind, signals) = detect_in_dir(Path::new("./my-app"));
assert!(matches!(kind, ProjectKind::Rust | ProjectKind::Node | _));
println!("matched on: {:?}", signals);

let projects = discover(Path::new("./my-monorepo"), &DiscoverOptions::default());
for p in projects {
    println!("{} -> {:?} at {}", p.label, p.kind, p.rel_path);
}

Features

• serde (default) — derives Serialize on the public types and exposes POSIX-path serializers in [path_norm]. Disable with default-features = false if you only need the detection logic.
