Shell yeah or shell no?
Lilush – LuaJIT static runtime and shell
A tiny one-file supertool sparks awe, doubts, and wild Lua dreams
TLDR: Lilush is a tiny, one‑file tool that runs scripts and acts like a shell, with internet, crypto, and built‑in apps—no installs. The crowd is split: hype and moonshot wishes (bare metal, graphics) vs pragmatic demands for clear API docs, turning a mini tool into a big debate.
Lilush dropped like a pocket-sized power plant: a single under‑3MB file that runs the fast LuaJIT language and doubles as a sleek shell, loaded with networking, crypto, filesystem tricks, and terminal toys—no installs, no dependencies. Fans called it a “busybox for developers,” swooning over drop‑in Docker use and ship‑anywhere vibes. But the community’s mood is delightfully messy. One veteran sighed that Lua keeps birthing compact, opinionated toolkits, name‑checking the now‑quiet luapower. Another waved a pointer to gsl‑shell, because of course every tiny tool has cousins.
Then the dreamers crashed the party: “Does this run on bare metal?” and “Can we get graphics?”—cue fantasies of rewriting userland in Love2D, the game engine. Practical voices slammed the brakes: where’s the API documentation? If you’re promising SSL (secure websites), HTTP servers, Redis, and even WireGuard in one file, people want clear how‑to’s before touching it. The shell’s Kitty‑keyboard requirement sparked jokes—Kitty or bust—while smart prompts and built‑ins like kat, netstat, and wgcli earned nods. The vibe? Big hype for a tiny powerhouse, tug‑of‑war between imagination and impatience, and a chorus chanting: ship the docs, then we’re in.
Key Points
- •Lilush is a statically compiled LuaJIT runtime and Linux shell delivered as a single binary under 3MB with no external dependencies.
- •It includes networking (TCP/UDP with SSL), a full HTTP(S) client, and an HTTP/1.1 server powered by WolfSSL compiled into the binary.
- •Built-in modules cover cryptography, filesystem and process utilities, terminal UI with TSS, Markdown, Redis protocol, JSON, Base64, and embedded WireGuard and ACMEv2 clients.
- •The shell offers smart prompts, tab completions, intelligent navigation/history search, and built-in tools like kat, ktl, netstat, dig, and wgcli.
- •Lilush requires a compatible terminal supporting Kitty’s keyboard protocol, provides signed release binaries, and includes examples (RELIW, zxkitty) built with it.
