Hey, folks! Today we want to talk about the wonderful read-eval-print-loop (REPL). Thanks to WebAssembly (Wasm), it's becoming increasingly common for programming language websites to embed a REPL in which passersby can easily evaluate code and get a feel for the language without having to install anything on their computer. We'd like to do the same thing for our language of choice, Guile Scheme,

Hoot is a Spritely project which provides a full-featured WebAssembly (Wasm) toolkit in Scheme. Hoot includes a Scheme to Wasm compiler, allowing Scheme code to run in recent browsers as a first-class citizen. Hoot requires no external tools and provides its own Wasm assembler and linker, and additionally contains a fully featured development environment including a disassembler, interpreter, and

Hey there, it’s been awhile! We’re back to share some more exciting news about Guile Hoot, a WebAssembly toolchain and Scheme→WASM compiler. In our last post we demonstrated that the Guile Hoot toolchain can be used to assemble programs written in WebAssembly Text (WAT) format, which allowed us to develop for the WASM-4 fantasy console. That was pretty cool, of course, but our goal is to compile S

This blogpost focuses on our second Spring Lisp Game Jam 2023 entry, wasm4-wireworld, an implementation of Wireworld on top of Hoot's lower-level assembly tools which are a part of our Guile → WASM project to bring Spritely Goblins-powered distributed applications to the common web browser. For our entry, we targeted WASM-4, a "fantasy console" which uses low-level WebAssembly constructs. In fact,

It's been just over three months since we announced the Guile on WebAssembly project (codenamed Hoot). Since then we've brought on two fantastic hackers to develop the project and progress has been quick. We now are at the point where we have things to show: we can now compile various Scheme procedures directly to WebAssembly. Let's clarify that: by compiling directly to WebAssembly, we mean they
