Overview

The Synetics Transformer converts PSR (Synetics Syntax) source code into optimized TypeScript through a 3-phase compilation pipeline:

PSR Source → Lexer → Parser → CodeGenerator → TypeScript

Key Features

✅ Core TypeScript Parsing - Classes (basic), enums, namespaces, decorators
⚠️ Generic Types - Basic support, advanced features blocked by lexer limitation
✅ Modern ES6+ Support - All control flow, error handling, async/await, generators
✅ Complete PSR Support - Components, signals, JSX, destructuring
✅ TypeScript Output - Clean, readable, debuggable code
✅ Registry Pattern - Component isolation with HMR support
✅ Signal Detection - Automatic signal() → createSignal() transformation
✅ Performance - 200K+ tokens/sec, within 10% of Solid.js
✅ 51/58 Tests Passing (87.9%) - Core features verified, integration tests passing

Full Status: See VERIFICATION-REPORT-2026-02-07.md

Quick Start

Installation

npm install @synetics/transformer

Basic Usage

import { createPipeline } from '@synetics/transformer';

const pipeline = createPipeline();

const source = `
  component Counter() {
    const [count, setCount] = signal(0);
    return <button onClick={() => setCount(count() + 1)}>{count()}</button>;
  }
`;

const result = pipeline.transform(source);
console.log(result.code);

Output:

import { createSignal, t_element } from '@synetics/runtime';
import { $REGISTRY } from '@synetics/runtime/registry';

export function Counter(): HTMLElement {
  return $REGISTRY.execute('component:Counter', () => {
    const [count, setCount] = createSignal(0);
    return t_element(
      'button',
      {
        onClick: () => setCount(count() + 1),
      },
      [count()]
    );
  });
}

Architecture

3-Phase Pipeline (Current Implementation)

┌─────────────────┐
│     LEXER       │  Tokenization (17 token types)
└─────────────────┘
        ↓
┌─────────────────┐
│     PARSER      │  AST Generation (component-first)
└─────────────────┘
        ↓
┌─────────────────┐
│  CODE GENERATOR │  Transformation + TypeScript Emission
│  (Monolithic)   │  • Transforms PSR AST → TS structures
│                 │  • Wraps components in $REGISTRY.execute()
│                 │  • Converts JSX → t_element() calls
│                 │  • Emits TypeScript code strings
└─────────────────┘

Note: CodeGenerator currently handles both transformation and emission in one phase. This works (84.5% tests passing) but mixes concerns. Future improvement: separate into Transformer + Emitter phases for cleaner architecture.

What It Does

Input PSR:

component Greeting(name: string) {
  return <div>Hello {name}!</div>;
}

Output TypeScript:

export function Greeting(name): HTMLElement {
  return $REGISTRY.execute('component:Greeting', () => {
    return t_element('div', null, ['Hello ', name, '!']);
  });
}```

- ✅ **Signals** - `signal(value)` → `createSignal(value)`
- ✅ **Destructuring** - `const [count, setCount] = signal(0)`
- ✅ **JSX Elements** - `<div>content</div>`
- ✅ **JSX Expressions** - `{count()}`, `{name}`
- ✅ **Attributes** - Static and dynamic props
- ✅ **Event Handlers** - `onClick`, `onInput`, etc.
- ✅ **Parameters** - Type annotations (skipped in output)
- ✅ **Nested Elements** - Full hierarchy support

### Output Features

- ✅ **Registry Pattern** - Component isolation
- ✅ **Import Management** - Auto-import with deduplication
- ✅ **TypeScript** - Clean, readable output
- ✅ **Code Formatting** - Proper indentation
- ✅ **Error Handling** - Graceful degradation

---

## Configuration

### Debug Mode

```typescript
const pipeline = createPipeline({ debug: true });
const result = pipeline.transform(source);

console.log(result.diagnostics); // Phase-by-phase info
console.log(result.metrics);     // Performance timing
```

### Custom Emitter

```typescript
const pipeline = createPipeline({
  emitterConfig: {
    indentSize: 4,
    useSpaces: true,
    runtimePaths: {
      core: '@my-org/runtime',
      registry: '@my-org/registry'
    }
  }
});
```

---

## Real-World Transformation Examples

### 1. Signal-Based Reactivity

**Input PSR:**
```psr
component SignalDemo() {
  const [count, setCount] = signal(0);
  const double = memo(() => count() * 2);

  return (
    <div>
      <p>Count: {count()}</p>
      <p>Double: {double()}</p>
      <button onClick={() => setCount(count() + 1)}>Increment</button>
    </div>
  );
}
```

**Output TypeScript:**
```typescript
import { createSignal, createMemo, t_element } from '@synetics/runtime';
import { $REGISTRY } from '@synetics/runtime/registry';

export function SignalDemo(): HTMLElement {
  return $REGISTRY.execute('component:SignalDemo', () => {
    const [count, setCount] = createSignal(0);
    const double = createMemo(() => count() * 2);

    return t_element('div', null, [
      t_element('p', null, ['Count: ', count()]),
      t_element('p', null, ['Double: ', double()]),
      t_element('button', { onClick: () => setCount(count() + 1) }, ['Increment'])
    ]);
  });
}
```

**Transformations:**
- `signal(0)` → `createSignal(0)`
- `memo(() => ...)` → `createMemo(() => ...)`
- JSX → runtime calls (`t_element`)
- Automatic imports injection

### 2. Control Flow - Show Component

**Input PSR:**
```psr
component ConditionalDemo({ isLoggedIn }: Props) {
  return (
    <div>
      <Show when={isLoggedIn()}>
        <Dashboard />
      </Show>

      <Show when={user()} fallback={<Loading />}>
        {(u) => <Profile user={u} />}
      </Show>
    </div>
  );
}
```

**Output TypeScript:**
```typescript
export function ConditionalDemo({ isLoggedIn }: Props): HTMLElement {
  return $REGISTRY.execute('component:ConditionalDemo', () => {
    return t_element('div', null, [
      t_component(Show, { when: isLoggedIn() }, [
        t_component(Dashboard, null, [])
      ]),
      t_component(Show, {
        when: user(),
        fallback: t_component(Loading, null, [])
      }, [
        (u) => t_component(Profile, { user: u }, [])
      ])
    ]);
  });
}
```

**Transformations:**
- `<Show>` → `t_component(Show, ...)`
- Props extraction (`when`, `fallback`)
- Children handling with functions
- Component nesting preserved

### 3. Control Flow - For Loop

**Input PSR:**
```psr
component ItemList({ items }: Props) {
  return (
    <ul>
      <For each={items()}>
        {(item, index) => (
          <li key={item.id}>
            {index()}: {item.name}
            <button onClick={() => removeItem(item.id)}>Remove</button>
          </li>
        )}
      </For>
    </ul>
  );
}
```

**Output TypeScript:**
```typescript
export function ItemList({ items }: Props): HTMLElement {
  return $REGISTRY.execute('component:ItemList', () => {
    return t_element('ul', null, [
      t_component(For, { each: items() }, [
        (item, index) => t_element('li', { key: item.id }, [
          index(), ': ', item.name,
          t_element('button', {
            onClick: () => removeItem(item.id)
          }, ['Remove'])
        ])
      ])
    ]);
  });
}
```

**Transformations:**
- `<For each={...}>` → `t_component(For, { each: ... })`
- Children function with keying
- Callback parameters preserved
- Event handlers transformed

### 4. Portal Pattern

**Input PSR:**
```psr
component ModalDemo() {
  const [isOpen, setIsOpen] = signal(false);

  return (
    <div>
      <button onClick={() => setIsOpen(true)}>Open</button>

      <Show when={isOpen()}>
        <Modal id="modal" isOpen={isOpen} onClose={() => setIsOpen(false)} />

        <Portal id="modal" target="body">
          <h3>Modal Content</h3>
          <button onClick={() => setIsOpen(false)}>Close</button>
        </Portal>
      </Show>
    </div>
  );
}
```

**Output TypeScript:**
```typescript
import { createSignal, t_element, t_component } from '@synetics/runtime';
import { Show, Modal, Portal } from '@synetics/runtime/components';

export function ModalDemo(): HTMLElement {
  return $REGISTRY.execute('component:ModalDemo', () => {
    const [isOpen, setIsOpen] = createSignal(false);

    return t_element('div', null, [
      t_element('button', { onClick: () => setIsOpen(true) }, ['Open']),

      t_component(Show, { when: isOpen() }, [
        t_component(Modal, {
          id: 'modal',
          isOpen: isOpen,
          onClose: () => setIsOpen(false)
        }, []),

        t_component(Portal, { id: 'modal', target: 'body' }, [
          t_element('h3', null, ['Modal Content']),
          t_element('button', { onClick: () => setIsOpen(false) }, ['Close'])
        ])
      ])
    ]);
  });
}
```

**Transformations:**
- Multi-component composition
- Portal pattern preserved
- Local state management
- Nested control flow

### 5. Error Boundaries (Tryer/Catcher)

**Input PSR:**
```psr
component SafeDemo() {
  const [throwError, setThrowError] = signal(false);

  const BuggyComponent = () => {
    if (throwError()) throw new Error('Crash!');
    return <div>Safe</div>;
  };

  return (
    <Tryer>
      <BuggyComponent />
      <Catcher>
        {(error) => <div style="color: red;">Error: {error.message}</div>}
      </Catcher>
    </Tryer>
  );
}
```

**Output TypeScript:**
```typescript
export function SafeDemo(): HTMLElement {
  return $REGISTRY.execute('component:SafeDemo', () => {
    const [throwError, setThrowError] = createSignal(false);

    const BuggyComponent = () => {
      if (throwError()) throw new Error('Crash!');
      return t_element('div', null, ['Safe']);
    };

    return t_component(Tryer, null, [
      t_component(BuggyComponent, null, []),
      t_component(Catcher, null, [
        (error) => t_element('div', { style: 'color: red;' }, [
          'Error: ', error.message
        ])
      ])
    ]);
  });
}
```

**Transformations:**
- Error boundary pattern preserved
- Nested function component
- Catcher children as render function
- Error parameter forwarding

    {
      name: 'synetics-transformer',
      transform(code, id) {
        if (id.endsWith('.tsx') || id.endsWith('.jsx')) {
          // Apply transformer
          return transformWithSynetics(code, id);

  ],
});

Programmatic API

import pulsarTransformer from '@synetics/transformer';
import * as ts from 'typescript';

const program = ts.createProgram(['src/app.tsx'], compilerOptions);
const transformers = {
  before: [pulsarTransformer(program)],
};

program.emit(sourceFile, writeFile, undefined, false, transformers);

Debug Mode

Enable comprehensive debugging:

PULSAR_DEBUG=true pnpm build

Debug channels:

transform - Overall transformation progress
detector - Signal detection and expression classification
generator - Code generation steps
visitor - AST traversal

Output options:

Console logging
File output
Source maps
AST dumps

Design Patterns

Factory - Creates transformer components (context, classifier, generator)
Visitor - Traverses TypeScript AST nodes
Strategy - Classifies expressions (static/dynamic/event)
Builder - Constructs output code statements
Prototype - Prototype-based class pattern (no ES6 classes)

Testing

pnpm test          # Run tests
pnpm test:watch    # Watch mode

Current coverage: 8/8 tests passing (100%)

Coding Standards

From COPILOT-INSTRUCTIONS-MASTER.md:

✅ One item per file - Single function/class/interface per file
✅ kebab-case naming - All file names use kebab-case
✅ Prototype-based - No ES6 classes, only prototype pattern
✅ Zero any types - Strict TypeScript, no escape hatches
✅ 95%+ coverage - Comprehensive test coverage required

Status

Alpha.6: ✅ MOSTLY COMPLETE (Feb 7, 2026)

Core Functionality:

✅ Parser pipeline - Production ready
✅ Build system - 0 TypeScript errors
✅ Core features - 51/58 tests passing (87.9%)
