Llux

Llux is a tool for independent creators.

It turns your interface ideas into native software that runs anywhere—without platform lock-in, hidden dependencies, or surprises.

You describe the intent. Llux compiles it to a binary. You own it.

The Architecture

Every interactive system—whether a smart-home dashboard, a CNC machine HMI, or a museum installation—follows the same pattern: Surface ↔ Transit ↔ Engine.

Llux compiles the Surface and the Transit rules. You bring the Engine.

No platform lock-in. No hidden dependencies. No surprises.

What It Looks Like

Here is the active language direction. You write the contract…

# Contract (app.llux)
app state {
    count: int = 0
}

action Increment(amount: int = 1) {
    app.count += amount
}

…and the surface in Markdown:

# Surface (app.llux.md)
::: page
  ::: flex gap-4
    ::: Label { @text <- "Count: " + app.count }
    ::: Slider { @value <-> app.count min=0 max=100 }
    ::: Button { @press -> app.increment label="+1" }
  :::
:::

Key:

• <- = inbound (state → UI)
• <-> = sync (state ↔ UI)
• -> = outbound (UI → state)

Who This Is For

Llux is built for independent creators, UI engineers, native developers, and educators who want to build software that runs anywhere without being tied to a single platform. Whether you use SwiftUI, Qt, React, or plain C—Llux gives you a clean path to native binaries.

---

Current Status

Pre-release early-to-mid alpha. The core toolchain exposes a llux CLI and a C-based compiler with the zero-dependency dump UI engine. Translators for SwiftUI, Qt/QML, HTML, and React are planned.

In Plain English (Quick Answers)

• Llux is a compiler, not a framework or runtime. It turns UI descriptions into native executables (.exe, .app, Linux ELF).
• You write two files: .llux for state/logic, .llux.md for the layout. Llux compiles them into one app.
• dump is the built-in renderer — zero dependencies, no browser, no Electron.
• Today: CLI and basic native builds work. Tomorrow: SwiftUI, Qt, React, and web targets.
