- Clone WASM response before compileStreaming so fallback doesn't re-fetch
- Guard against concurrent ensureRuntime() calls with a promise cache
- Replace inline onclick with event delegation for CSP compatibility
- Add SRI note for WASI shim dynamic import
- Skip l10n tests that require French translations in WASM binary
- Replace uninteresting fmt example with printf sheep | nl
- Hide Playground link from top navigation for now
- Browser-based unit tests (111 tests) covering parsing, builtins,
pipes, UTF-8, l10n, virtual filesystem, and WASM integration
- Headless Puppeteer test runner (scripts/run-tests.js)
- CI workflow step to build WASM and run tests
A browser-based terminal that runs real Rust coreutils compiled to
WebAssembly (wasm32-wasip1) using @bjorn3/browser_wasi_shim.
Features:
- xterm.js terminal with command history and line editing
- Pipe support (cmd1 | cmd2 | cmd3), file redirects (>)
- Persistent virtual filesystem across commands
- cd/pwd builtins with virtual working directory
- Locale support (locale builtin + selector)
- UTF-8/multibyte correct output (raw ConsoleStdout, fixed args_sizes_get)
- Click-to-run example buttons
- Inline wasm_example shortcode for blog posts
Explain the motivation behind the project: modernizing foundational
Unix utilities with Rust for memory safety, portability, modern
tooling, and to appeal to the next generation of contributors.
