Edit Phase +You write EigenScript code in the editor (left panel). + +### 2. Compile Phase +When you click "Run" or press `Ctrl+Enter`: +1. JavaScript sends your code to `POST /compile` +2. The server creates a temporary `.eigs` file +3. It calls `eigenscript-compile --target wasm32-unknown-unknown --exec` +4. Returns the compiled `.wasm` binary (or errors) + +### 3. Execute Phase +The browser: +1. Receives the WASM binary +2. Instantiates it with an import object that provides: + - `eigen_print`: JavaScript function for plotting + - Math functions: `exp`, `sin`, `cos`, etc. +3. Calls `instance.exports.main()` + +### 4. Visualize Phase +Every time your code calls `print of x`: +1. WASM calls the imported `eigen_print(value)` +2. JavaScript intercepts it +3. Adds the value to the plot history +4. Redraws the canvas with the updated graph + +## Troubleshooting + +### "Failed to fetch /compile" +- Make sure `server.py` is running +- Check that you're accessing `http://localhost:8080`, not `file://` + +### "Compilation failed" +Common issues: +- **Syntax error**: Check your EigenScript syntax +- **Runtime not built**: Run `python3 build_runtime.py --target wasm32` in `src/eigenscript/compiler/runtime/` +- **No WASM toolchain**: Install WASI SDK or Emscripten (see [examples/wasm/README.md](../wasm/README.md)) + +### "malloc undefined" or similar +- Check that the import object in `index.html` provides all required functions +- The current version stubs out `malloc`/`free` - WASM uses internal memory + +### Visualization not updating +- Make sure your code calls `print of ` +- Check browser console (F12) for JavaScript errors +- Verify WASM is actually executing (check console output) + +## Architecture Details + +### Why a Local Server? + +The original plan (Pyodide) would run Python in the browser, but: +- Pyodide is 20MB+ download +- `llvmlite.binding` requires native C++ LLVM libraries +- Subprocess calls to `clang` don't work in browsers + +**Solution:** Run the compiler on your machine, stream WASM to the browser. + +### The Import Object + +WASM can't access browser APIs directly.
