Community packages live in the std-contrib catalog. A package is just a URL: it is fetched over HTTPS and inlined at compile time — no package manager, no install step, no lockfile. Every package is plain Lumen, statically typed, and tested.
Import a package's export straight from its URL and build as usual.
import greet from "https://lumen-lang.org/package/std-contrib/hello/hello.ts";
console.log(greet("world")); // Hello, world!lumen-lang.org/package/std-contrib/<name>/<file>.ts
redirects to the package's repository; the raw GitHub URL works too.
| Package | What it does |
|---|---|
| hello | Minimal greet function; the canonical URL-import example. |
| greeter | Two-file package; demonstrates recursive URL-relative imports. |
| args | Command-line flag and option parsing — hasFlag, optionValue, positional arguments. |
| mathx | Integer math helpers — gcd, lcm, ipow, isPrime, clampInt. |
| geo | 2D point helpers — distanceSq, manhattan. |
| quickjs | Embed a JavaScript sandbox via FFI; set, eval, and read values across the boundary. |
quickjs links a native library through the C FFI, so it is
built locally (copy its files and link the engine) rather than fetched purely by URL.
Its page documents the build.
One package per directory, statically typed, tested, current-language features only, with an entry in the catalog. See CONTRIBUTING in the std-contrib repository.
