Comline Playground

Type a .ids schema, see the diagnostics, the frozen IR, and the generated code — live, in the browser. Runs the actual comline-core + comline-codegen + the comline-language-server analysis (compiled to WASM), so what you see matches the CLI and comline-lsp.

Static — deploys to GitHub Pages, no server.

Layout

wasm/   comline-playground-wasm — the Rust crate, wasm-bindgen surface
          compile(source)                -> { ok, diagnostics, ir, units }
          generate(source, target, mode) -> { files, error }
          semantic_tokens / hover / completions   — the LSP handlers verbatim
        deps: comline-core, comline-codegen, comline-codegen-rust,
              comline-codegen-typescript, comline-language-server (git rev)
app/    a Vite site; a CodeMirror 6 editor whose highlighting, diagnostics,
        hover and autocomplete are all fed from the WASM (i.e. the LSP).
        The WASM runs in a Web Worker.
.github/workflows/deploy.yml   build WASM → build site → deploy to Pages

Develop

cd app
npm install
npm run dev        # runs wasm-pack, then Vite

Requires a Rust toolchain with the wasm32-unknown-unknown target and wasm-pack.

Deploy

Push to master. The workflow builds the WASM with wasm-pack, builds the site with Vite (base: "./", so it works under /<repo>/), and publishes app/dist to Pages. Enable Pages → "GitHub Actions" in the repo settings once.

Scope (v1)

One schema, namespace main; code and lib modes; rust and typescript targets. Multi-file packages, config (config.idp / comline.toml) input, a runtime demo, and docs embedding are follow-ups — see ComlineProject/docs → Design → Playground & tutorial.
