### Detect 64-bit Browser Architecture (JavaScript)

Source: https://github.com/roepstoep/lidraughts/blob/master/public/oops/diagnostics.html

This function checks if the current browser environment is 64-bit. It inspects the `navigator.userAgent` string for common 64-bit indicators and also checks `navigator.platform` for specific Linux and Mac platforms. It returns `true` if a 64-bit architecture is detected, otherwise `false`.

```JavaScript
function is64Bit() { const x64 = ['x86_64', 'x86-64', 'Win64','x64', 'amd64', 'AMD64']; for (const substr of x64) if (navigator.userAgent.includes(substr)) return true; return navigator.platform === 'Linux x86_64' || navigator.platform === 'MacIntel'; }
```

--------------------------------

### Gather WebAssembly (WASM) Capabilities Information (JavaScript)

Source: https://github.com/roepstoep/lidraughts/blob/master/public/oops/diagnostics.html

This function probes the browser's WebAssembly support. It checks for the existence of `WebAssembly`, `SharedArrayBuffer`, and `Atomics`. It then attempts to validate a minimal WASM module, test structured cloning with a WASM module, and verify shared memory and growable memory capabilities of `WebAssembly.Memory`. It returns an object detailing these capabilities and any errors encountered during the tests.

```JavaScript
function wasmInfo() { var info = { WebAssembly: typeof WebAssembly, SharedArrayBuffer: typeof SharedArrayBuffer, Atomics: typeof Atomics }; if (info.WebAssembly !== 'object') return info; var source = Uint8Array.of(0x0, 0x61, 0x73, 0x6d, 0x01, 0x00, 0x00, 0x00); info.mvp = WebAssembly.validate(source); if (!info.mvp) return info; try { window.postMessage(new WebAssembly.Module(source), '*'); info.structuredCloning = 'ok'; } catch (e) { info.structuredCloning = e.toString(); } if (info.SharedArrayBuffer !== 'function') return info; var mem = new WebAssembly.Memory({shared: true, initial: 8, maximum: 16}); info.sharedMem = mem.buffer instanceof SharedArrayBuffer; try { mem.grow(8); info.growableMem = 'ok'; } catch (e) { info.growableMem = e.toString(); } return info; }
```

--------------------------------

### Aggregate and Output Browser Diagnostics (JavaScript)

Source: https://github.com/roepstoep/lidraughts/blob/master/public/oops/diagnostics.html

This code block aggregates the results from all the previously defined diagnostic functions into a single `info` object. It includes general navigator properties, hardware concurrency, device memory, and the results from WASM, PNaCl, board height fix, touch events, animation, local storage, and service worker checks. Finally, it serializes this `info` object to a JSON string and writes it directly to the document for display.

```JavaScript
var info = { diagnosticsVersion: 4, navigator: { userAgent: navigator.userAgent, platform: navigator.platform, chrome: !!window.chrome, is64Bit: is64Bit(), hardwareConcurrency: navigator.hardwareConcurrency, deviceMemory: navigator.deviceMemory }, wasm: wasmInfo(), pnacl: pnaclInfo(), needsBoardHeightFix: needsBoardHeightFix(), hasTouchEvents: 'ontouchstart' in window, animate: typeof document.createElement('div').animate, localStorage: localStorageInfo(), serviceWorker: serviceWorkerInfo() }; document.write(JSON.stringify(info));
```

--------------------------------

### Check PNaCl (Portable Native Client) MIME Type Support (JavaScript)

Source: https://github.com/roepstoep/lidraughts/blob/master/public/oops/diagnostics.html

This function determines if the browser supports PNaCl (Portable Native Client) by checking for the presence of the 'application/x-pnacl' MIME type in `navigator.mimeTypes`. It returns an object indicating this support.

```JavaScript
function pnaclInfo() { return { mimeType: 'application/x-pnacl' in navigator.mimeTypes }; }
```

--------------------------------

### Retrieve Specific Local Storage Items (JavaScript)

Source: https://github.com/roepstoep/lidraughts/blob/master/public/oops/diagnostics.html

This function retrieves the values of a predefined list of interesting keys from `window.localStorage`. It iterates through the list and stores the retrieved values in an object, which is then returned. This is useful for debugging application-specific settings and user preferences.

```JavaScript
function localStorageInfo() { var intresting = [ 'client-eval-enabled', 'analyse.ceval.watchdog3.pnacl', 'analyse.ceval.max-depth', 'analyse.ceval.multipv', 'analyse.ceval.threads', 'analyse.ceval.hash-size', 'analyse.ceval.infinite', 'ceval.pool.start', 'ceval.fen', 'just-notified', 'push-subscribed', 'grid', 'resize-nag', 'speech.enabled', 'sound-volume', 'surl6' ]; var info = {}; for (var i = 0; i < intresting.length; i++) { info[intresting[i]] = window.localStorage.getItem(intresting[i]); } return info; }
```

--------------------------------

### Gather Service Worker and Notification API Information (JavaScript)

Source: https://github.com/roepstoep/lidraughts/blob/master/public/oops/diagnostics.html

This function collects information about the browser's support for Service Workers, Permissions API, Notification API, PushManager, and the `fetch` API. If the Notification API is supported, it also retrieves the current notification permission status. This helps in understanding the browser's capabilities for background synchronization and push notifications.

```JavaScript
function serviceWorkerInfo() { var info = { 'navigator': 'serviceWorker' in navigator, 'permissions': 'permissions' in navigator, 'Notification': 'Notification' in window, 'PushManager': 'PushManager' in window, 'fetch': typeof fetch }; if (info.Notification) info['Notification.permission'] = Notification.permission; return info; }
```

--------------------------------

### CSS Global Reset and Base Styles

Source: https://github.com/roepstoep/lidraughts/blob/master/public/font/font-src/icons-reference.html

### JavaScript to Conditionally Remove Upgrade Message

Source: https://github.com/roepstoep/lidraughts/blob/master/public/oops/browser.html

This JavaScript snippet checks for the presence of a CSS custom property '--grid' on the document's body element. If this property is found, it indicates that the browser supports a modern layout, and the entire 'upgrade' element is removed from the DOM, effectively hiding the outdated browser message.

```javascript
if (getComputedStyle(document.body).getPropertyValue('--grid')) document.getElementById('upgrade').remove();
```

--------------------------------
