+# Changelog
+
+## 2025-11-30 - 3.0.0 - BREAKING CHANGE(smartwatch)
+Introduce Smartwatch: cross-runtime native file watching for Node.js, Deno and Bun; rename smartchok to smartwatch and bump major version to 2.0.0
+
+- Rename public API and docs from Smartchok to Smartwatch and update package metadata for the new module name.
+- Replace chokidar with native watchers and picomatch-based glob filtering to enable cross-runtime support (Node.js, Deno, Bun).
+- Add watcher factory and runtime-specific implementations: watchers/index.ts, watcher.node.ts, watcher.deno.ts.
+- Add WriteStabilizer (ts/utils/write-stabilizer.ts) to provide awaitWriteFinish functionality via polling.
+- Introduce @push.rocks/smartenv for runtime detection and remove direct chokidar dependency; update dependencies accordingly.
+- Update tests (test/test.ts) and documentation (readme.md, readme.hints.md) to reflect API/name changes and new architecture.
+- Bump package version to 2.0.0 to mark breaking changes in API and behavior.
+
+## 2025-11-29 - 1.2.0 - feat(core)
+Migrate to chokidar 5.x, add picomatch filtering and update test/dev dependencies
+
+- Upgrade runtime dependencies: chokidar -> ^5.0.0 and picomatch -> ^4.0.3; bumped related @push.rocks packages versions.
+- Upgrade devDependencies: @git.zone/tsbuild, @git.zone/tsrun and @git.zone/tstest to newer v2/v3 releases; updated @types/node.
+- Updated README and readme.hints to document migration to chokidar 5.x and dev dependency changes.
+- Tests updated to use @git.zone/tstest/tapbundle (import change) and test runner start changed to export default tap.start().
+- Smartchok implementation updated to extract glob base paths, watch base directories and filter events via picomatch matchers (shouldWatchPath + event filtering).
+- Note: ts/00_commitinfo_data.ts still references chokidar 4.x in the description and should be updated to reflect the migration.
+
+## 2025-06-26 - 1.1.1 - fix(package.json)
+Add packageManager field to package.json for pnpm configuration
+
+- Added "packageManager": "pnpm@10.11.0+sha512.6540583f41cc5f628eb3d9773ecee802f4f9ef9923cc45b69890fb47991d4b092964694ec3a4f738a420c918a333062c8b925d312f42e4f0c263eb603551f977" to package.json
+
+## 2025-06-26 - 1.1.0 - feat(Smartchok)

+# smartchok - Technical Hints
 
+## Native File Watching (v2.0.0+)
+
+The module now uses native file watching APIs instead of chokidar, providing cross-runtime support for Node.js, Deno, and Bun.
+
+### Architecture
+
+```
+ts/
+├── smartwatch.classes.smartwatch.ts   # Main Smartwatch class
+├── smartwatch.plugins.ts              # Dependencies (smartenv, picomatch, etc.)
+├── watchers/
+│   ├── index.ts                       # Factory with runtime detection
+│   ├── interfaces.ts                  # IWatcher interface and types
+│   ├── watcher.node.ts                # Node.js/Bun implementation (fs.watch)
+│   └── watcher.deno.ts                # Deno implementation (Deno.watchFs)
+└── utils/
+    └── write-stabilizer.ts            # awaitWriteFinish polling implementation
+```
+
+### Runtime Detection
+
+Uses `@push.rocks/smartenv` v6.x for runtime detection:
+- **Node.js/Bun**: Uses native `fs.watch()` with `{ recursive: true }`
+- **Deno**: Uses `Deno.watchFs()` async iterable
+
+### Dependencies
+
+- **picomatch**: Glob pattern matching (zero deps, well-maintained)
+- **@push.rocks/smartenv**: Runtime detection (Node.js, Deno, Bun)
+- **@push.rocks/smartrx**: RxJS Subject/Observable management
+- **@push.rocks/smartpromise**: Deferred promise utilities
+- **@push.rocks/lik**: Stringmap for pattern storage
+
+### Why picomatch?
+
+Native file watching APIs don't support glob patterns. Picomatch provides glob pattern matching with:
+- Zero dependencies
+- 164M+ weekly downloads
+- Excellent security profile
+- Full glob syntax support
+
+### Event Handling
+
+Native events are normalized to a consistent interface:
+
+| Node.js/Bun Event | Deno Event | Normalized Event |
+|-------------------|------------|------------------|
+| `rename` (file exists) | `create` | `add` |
+| `rename` (file gone) | `remove` | `unlink` |
+| `change` | `modify` | `change` |
+
+### awaitWriteFinish Implementation
+
+The `WriteStabilizer` class replaces chokidar's built-in write stabilization:
+- Polls file size until stable (configurable threshold: 300ms default)
+- Configurable poll interval (100ms default)
+- Handles file deletion during write detection
+
+### Platform Requirements
+
+- **Node.js 20+**: Required for native recursive watching on all platforms
+- **Deno**: Works on all versions with `Deno.watchFs()`
+- **Bun**: Uses Node.js compatibility layer
+
+### Testing
+
+```bash
+pnpm test
+```
+
+Tests verify:
+- Creating Smartwatch instance
+- Adding glob patterns
+- Receiving 'add' events for new files
+- Graceful shutdown
+
+## Dev Dependencies
+
+- Using `@git.zone/tstest` v3.x with tapbundle
+- Import from `@git.zone/tstest/tapbundle`

 ## Usage
 
-The `@push.rocks/smartchok` package provides a convenient and smart wrapper around the popular `chokidar` library for file watching with enhanced features such as observable support for filesystem events. This guide will introduce you to the usage of `@push.rocks/smartchok`, leveraging TypeScript for type safety and better developer experience.
-
-### Setting Up Your Project
-
-To use `@push.rocks/smartchok`, ensure your project is set up to use TypeScript and ECMAScript modules (ESM). You need to have a `tsconfig.json` file at the root of your project with the following minimum settings:
-
-```json
-{
-  "compilerOptions": {
-    "target": "esnext",
-    "module": "esnext",
-    "moduleResolution": "node",
-    "esModuleInterop": true,
-    "declaration": true,
-    "outDir": "./dist",
-    "strict": true
-  },
-  "include": ["src/**/*"],
-  "exclude": ["node_modules", "dist"]
-}
-```
-
-This configuration enables TypeScript compilation targeting the latest ECMAScript standards and includes all TypeScript files (`*.ts`) in your `src` directory.
-
 ### Basic Setup
 
-To start using `smartchok`, first import it into your TypeScript file:
-
 ```typescript
-import { Smartchok } from '@push.rocks/smartchok';
+import { Smartwatch } from '@push.rocks/smartwatch';
-```
 
-#### Initializing Smartchok
+// Create a watcher with glob patterns
-
+const watcher = new Smartwatch([
-Create an instance of `Smartchok` by specifying an array of glob patterns to watch:
+  './src/**/*.ts',           // Watch all TypeScript files in src
-
+  './public/assets/**/*'     // Watch all files in public/assets
-```typescript
-const smartchokInstance = new Smartchok([
-  './src/**/*.ts',          // Watch all TypeScript files in the src directory
-  './public/assets/**/*'    // Watch all files in the public/assets directory
 ]);
+
+// Start watching
+await watcher.start();
 ```
 
-#### Adding and Removing Files Dynamically
+### Subscribing to File Events
 
-You can dynamically add and remove paths from being watched by using the `add` and `remove` methods:
+Use RxJS observables to react to file system changes:
 
 ```typescript
-// Add additional files or patterns
+// Get an observable for file changes
-smartchokInstance.add(['./tests/**/*.spec.ts']);
+const changeObservable = await watcher.getObservableFor('change');
-
-// Remove specific patterns from watch
-smartchokInstance.remove('./src/**/*.test.ts');
-```
-
-#### Handling Filesystem Events
-
-`smartchok` leverages RxJS observables to notify about filesystem events. This allows you to respond to various events such as file additions, changes, and deletions with ease.
-
-First, start the watcher:
-
-```typescript
-await smartchokInstance.start();
-```
-
-Then, subscribe to an event:
-
-```typescript
-const changeObservable = await smartchokInstance.getObservableFor('change');
 
 changeObservable.subscribe({
   next: ([path, stats]) => {
     console.log(`File changed: ${path}`);
   },
   error: (err) => {
-    console.error(`An error occurred: ${err}`);
+    console.error(`Error: ${err}`);
   }
 });
+
+// Watch for new files
+const addObservable = await watcher.getObservableFor('add');
+addObservable.subscribe(([path]) => {
+  console.log(`File added: ${path}`);
+});
+
+// Watch for deleted files
+const unlinkObservable = await watcher.getObservableFor('unlink');
+unlinkObservable.subscribe(([path]) => {
+  console.log(`File deleted: ${path}`);
+});
 ```
 
-Supported events include 'add', 'change', 'unlink' (for deletions), and others. Refer to the chokidar documentation for a full list of events.
+### Supported Events
 
-#### Stopping the Watcher
+| Event | Description |
+|-------|-------------|
+| `add` | File has been added |
+| `addDir` | Directory has been added |
+| `change` | File has been changed |
+| `unlink` | File has been removed |
+| `unlinkDir` | Directory has been removed |
+| `error` | Error occurred |
+| `ready` | Initial scan complete |
+| `raw` | Raw event from the underlying watcher |
 
-To stop watching for file changes, simply call:
+### Dynamic Watch Management
+
+Add or remove patterns while the watcher is running:
 
 ```typescript
-await smartchokInstance.stop();
+const watcher = new Smartwatch(['./src/**/*.ts']);
+await watcher.start();
+
+// Add more patterns to watch
+watcher.add(['./tests/**/*.spec.ts', './config/*.json']);
+
+// Remove a pattern
+watcher.remove('./src/**/*.test.ts');
 ```
 
-### Advanced Usage
+### Stopping the Watcher
 
-Beyond the basics, `smartchok` allows for more complex monitoring scenarios, such as debounced notifications for rapid changes, filtering events, and integrating with other observables for complex asynchronous workflows.
+```typescript
+// Stop watching when done
+await watcher.stop();
+```
 
-### Conclusion
+### Complete Example
 
-`@push.rocks/smartchok` provides a robust, observable-based wrapper around `chokidar`, making it an excellent choice for projects requiring efficient and flexible file monitoring. Its integration with RxJS opens up a wide array of possibilities for handling file system events in a reactive manner, making your code more concise, readable, and maintainable.
+```typescript
+import { Smartwatch } from '@push.rocks/smartwatch';
 
-By following the guidelines provided in this document, you should now be equipped to integrate `@push.rocks/smartchok` into your TypeScript project, enhancing its capabilities with efficient file system monitoring.
+async function watchProject() {
+  // Initialize with patterns
+  const watcher = new Smartwatch([
+    './src/**/*.ts',
+    './package.json'
+  ]);
+
+  // Start the watcher
+  await watcher.start();
+  console.log('👀 Watching for changes...');
+
+  // Subscribe to changes
+  const changes = await watcher.getObservableFor('change');
+  changes.subscribe(([path, stats]) => {
+    console.log(`📝 Modified: ${path}`);
+    console.log(`   Size: ${stats?.size ?? 'unknown'} bytes`);
+  });
+
+  // Subscribe to new files
+  const additions = await watcher.getObservableFor('add');
+  additions.subscribe(([path]) => {
+    console.log(`✨ New file: ${path}`);
+  });
+
+  // Subscribe to deletions
+  const deletions = await watcher.getObservableFor('unlink');
+  deletions.subscribe(([path]) => {
+    console.log(`🗑️ Deleted: ${path}`);
+  });
+
+  // Handle graceful shutdown
+  process.on('SIGINT', async () => {
+    console.log('\n🛑 Stopping watcher...');
+    await watcher.stop();
+    process.exit(0);
+  });
+}
+
+watchProject();
+```
+
+## How It Works
+
+Since chokidar 4.x+ no longer supports glob patterns natively, smartwatch handles glob pattern matching internally using [picomatch](https://github.com/micromatch/picomatch). This means you get the familiar glob syntax while benefiting from chokidar's efficient file watching capabilities.
+
+When you provide glob patterns:
+1. **Base path extraction** - smartwatch extracts the static base path from each pattern
+2. **Efficient watching** - chokidar watches the base directories
+3. **Pattern filtering** - Events are filtered through picomatch matchers before being emitted
+
+## API Reference
+
+### `Smartwatch`
+
+#### Constructor
+
+```typescript
+new Smartwatch(patterns: string[])
+```
+
+Creates a new Smartwatch instance with the given glob patterns.
+
+#### Methods
+
+| Method | Returns | Description |
+|--------|---------|-------------|
+| `start()` | `Promise<void>` | Starts watching for file changes |
+| `stop()` | `Promise<void>` | Stops the file watcher |
+| `add(patterns: string[])` | `void` | Adds patterns to watch |
+| `remove(pattern: string)` | `void` | Removes a pattern from watching |
+| `getObservableFor(event: TFsEvent)` | `Promise<Observable<[string, Stats]>>` | Returns an RxJS observable for the specified event |
+
+#### Properties
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `status` | `'idle' \| 'starting' \| 'watching'` | Current watcher status |

+# Migration Plan: smartchok to Chokidar 4.x
+
+Command to reread CLAUDE.md: `cat /home/philkunz/.claude/CLAUDE.md`
+
+## MIGRATION COMPLETED ✅
+
+All phases of the migration have been successfully completed:
+
+## Current State Analysis
+
+- **Current dependency**: `@tempfix/watcher` v2.3.0 (a fork of fabiospampinato/watcher)
+- **Target**: Chokidar v4.0.3
+- **Major challenge**: Chokidar 4.x removed glob support, but smartchok heavily uses glob patterns
+
+## Migration Plan
+
+### Phase 1: Preparation
+1. Install chokidar 4.x and glob library for pattern matching
+   - `pnpm install chokidar@^4.0.3`
+   - `pnpm install picomatch` (for glob pattern matching)
+   - `pnpm uninstall @tempfix/watcher`
+
+### Phase 2: Code Changes
+
+#### 2.1 Update Plugin Imports (ts/smartchok.plugins.ts)
+- Remove `@tempfix/watcher` import
+- Add `chokidar` import
+- Add `picomatch` for glob pattern matching
+
+#### 2.2 Update Smartchok Class (ts/smartchok.classes.smartchok.ts)
+- Replace watcher initialization with chokidar
+- Implement custom glob filtering using picomatch
+- Update event mapping to match chokidar's event names
+- Adjust watcher options to match chokidar's API
+
+#### 2.3 Handle Glob Patterns
+Since chokidar 4.x removed glob support, we need to:
+- Parse glob patterns to extract base directories
+- Use chokidar to watch base directories
+- Use picomatch to filter events based on glob patterns
+- Ensure backward compatibility with existing API
+
+#### 2.4 Event Mapping
+Map chokidar events to existing smartchok events:
+- Keep existing event names for backward compatibility
+- Ensure all current functionality is preserved
+
+### Phase 3: Testing
+1. Run existing tests to ensure backward compatibility
+2. Add new tests for glob pattern handling
+3. Test edge cases with complex glob patterns
+4. Verify performance with large file sets
+
+### Phase 4: Documentation
+1. Update readme.md to reflect the change to chokidar 4.x
+2. Document any API changes (if any)
+3. Update version number in package.json
+
+## Technical Details
+
+### Key Differences to Handle:
+1. **Glob Support**: Implement custom glob filtering layer
+2. **API Changes**: Adapt initialization and option passing
+3. **Event Names**: Map between different event naming conventions
+4. **Minimum Node Version**: Ensure compatibility with Node 14+
+
+### Risk Mitigation:
+- Maintain backward compatibility with existing API
+- Extensive testing with current test suite
+- Consider keeping a legacy branch if breaking changes are unavoidable
