Hoot 0.10.0 Released

We are excited to announce the release of Hoot 0.10.0! Hoot is a Scheme to WebAssembly compiler backend for Guile, as well as a general purpose WebAssembly toolchain. In other words, Scheme in the browser!

This release contains new features and bug fixes and since the 0.9.0 release back in May.

On Friday (October 30th 2026), the autumn edition of the Lisp Game Jam will begin! It's a 10-day long game jam where participants make games using their favorite flavor of Lisp.

Does making a small web game in Scheme using Hoot sound appealing to you? Well, then we have just the thing to get you started: the Hoot game jam template! This template project has everything you need to start making an HTML5 game with Hoot quickly.

Bindings to the necessary web APIs to make an interactive game with HTML5 canvas

A Makefile for compiling, running a development web server, and generating a .zip bundle for uploading to itch.io

A very simple Breakout-like example game that demonstrates how to put all the pieces together

For more inspiration, here are some games made with Hoot for past jams:

$ guix pull $ guix install guile guile-hoot

Also, Hoot is now available in Debian, though it will take awhile for this release to make it there.

Otherwise, Hoot can be built from source via our release tarball. See the Hoot homepage for a download link and GPG signature.

Documentation for Hoot 0.10.0, including build instructions, can be found here.

For bug reports, pull requests, or just to follow along with development, check out the Hoot project on Codeberg.

If you build something cool with Hoot, let us know on our community forum!
