A browser-based ZX Spectrum live-coding environment
https://bazematic.demozoo.org/
At the NOVA 2023 demoparty, there was a live-coding jam organised on the premise of "if you can broadcast your screen, you can code in whatever tools you like". So, because I'm an awkward bugger, I decided to try my hand at live-coding for the Spectrum in Z80 assembler. Unfortunately, since no-one has made a dedicated live-coding environment for that, it involved a whole lot of switching between the emulator, text editor, and command line for the assembler.
bazematic is my attempt at addressing this obvious gap in the live-coding ecosystem. It brings together my JSSpeccy emulator, roudoudou's rasm assembler (cross-compiled to WebAssembly with Emscripten), and the Ace code editor into a single coder-friendly package.
Following the precedent of Bonzomatic being named after Bonzaj / Plastic who spearheaded live shader coding, bazematic is named after legendary Spectrum coder Baze / 3SC.
The following parameters can be passed in the URL:
mode:senderorgrabber. When either of these options is passed, the "Stream" panel is hidden and a websocket connection is immediately opened to the URL given inws. Ingrabbermode, the emulator window is left aligned (for easier OBS capturing) and all other panels are hidden, and the text editor is read-only.ws: the URL to connect to for the websocket.handle: an identifier to be sent as part of the JSON payload to the websocket server. This is intended to be used to identify the sender, and is not used by the client itself.
There isn't a proper build script right now - compiled assets from jsspeccy, rasm and ace are included directly into the repo.
- jsspeccy is built from commit 429daf15 with
npm run build- the contents ofdistare copied intojsspeccy - rasm is built from commit af8013ed of my fork, using
emmake makewith an emscripten environment active. The resultingrasm.jsandrasm.wasmare copied intorasm - ace is the
src-minsubtree of commit d065fe88
