Tish playground

Minimal web playground: UI in Tish (compiled to JS), user code compiled and run 100% in the browser (VM WASM + compiler WASM). Dev server written in Tish.

Layout

Path	Role
app/	Tish sources (main.tish, shell.tish, modular panels/)
public/	Static assets: index.html, playground.css, generated playground.js, tish_vm*.wasm, tish_compiler*.wasm
compiler-wasm/	Rust crate: tish compiler as WASM for browser
dev-server.tish	Static file server (Tish) for local dev

Prerequisites

• Rust + just (optional)
• wasm-bindgen-cli: cargo install wasm-bindgen-cli
• rustup target add wasm32-unknown-unknown
• Sibling checkout of Tish (default: ../tish). Override with TISH_ROOT.

Local Tish development: The playground uses the local tish repo (not npm). After pulling tish changes, run npm run install-tish to reinstall the CLI, then npm run verify to confirm JSX text (e.g. <h1>Web preview works!</h1>) compiles correctly.

Build & run

just dev

Builds the UI, VM WASM, and compiler WASM, then serves http://127.0.0.1:8765 via the Tish dev server.

Individual steps:

just build-app      # Tish → public/dist/playground.js
just build-vm       # tish_wasm_runtime → public/dist/tish_vm*.wasm
just build-compiler # tish-playground-compiler → public/dist/tish_compiler*.wasm

Swapping panels
