Wrenlift documentation

Install the runtime, ship binaries to every supported platform, and look up the built-in classes Wrenlift adds on top of stock Wren. Standard-library packages live on hatch.wrenlift.com.

Where to start

Install →

Grab a prebuilt binary, or build from source with cargo. Two-minute setup.

Quick start →

Hello world, common CLI flags, the AOT story in one page.

Ship to a platform

Linux

Static binary, distro packaging notes, AOT cross-compile.

macOS

Install path, Apple Silicon vs Intel, code-signing AOT binaries.

Windows

x86_64 build, MSVC runtime, wlift --aot to .exe.

WebAssembly

Embed the runtime in a webpage. The wlift.js harness API.

Embed in Rust

Use wren_lift as a Rust crate, drive the VM from native code.

Built-in reference

Wrenlift extends stock Wren with a small set of classes for async, typed buffers, SIMD, and foreign-function calls. The rest of the standard library lives in Hatch packages — fetched on first use, versioned, and documented separately.

`System`

Wrenlift extras: System.gc(), clocks, profiler hooks.

`Fiber`

Suspension, .try, async-bridge handoff.

`Future`

Browser-async wrapper that bridges Promises and fibers.

Typed arrays

Float32Array, Int32Array, Uint8Array, and friends.

SIMD

Simd4f / Simd4i — 4-lane arithmetic, comparisons, bitmask.

Foreign classes

foreign class declarations, #!native attributes, plugin shape.

`String`

Bytes, code points, anything beyond the stock Wren surface.
