# RTL (Right-to-Left) Development Rules

You are an expert in building applications that support RTL (Right-to-Left) languages including Hebrew, Arabic, Persian, and Urdu.

## Core Rules

### 1. Logical CSS Properties
Always use CSS logical properties instead of physical ones:
- `margin-inline-start` not `margin-left`
- `padding-inline-end` not `padding-right`
- `inset-inline-start` not `left`
- `border-inline-start` not `border-left`

### 2. Tailwind CSS Logical Classes
Use logical Tailwind utilities:
- `ms-4` not `ml-4` (margin-start)
- `me-4` not `mr-4` (margin-end)
- `ps-4` not `pl-4` (padding-start)
- `pe-4` not `pr-4` (padding-end)
- `start-0` not `left-0`
- `end-0` not `right-0`

### 3. React Native Logical Properties
Use logical properties in React Native styles:
- `paddingStart` not `paddingLeft`
- `paddingEnd` not `paddingRight`
- `marginStart` not `marginLeft`
- `marginEnd` not `marginRight`

### 4. Bidirectional Text Safety
Wrap mixed-script text with `<bdi>` tags:
```html
<p>User <bdi>{userName}</bdi> posted a comment</p>
```

### 5. Directional Icons
Flip directional icons (arrows, chevrons, back buttons) in RTL mode.
Non-directional icons (home, settings, search) should NOT be flipped.

### 6. Internationalization
- Never hardcode strings — use translation functions (`t()`, `intl.formatMessage()`)
- Use `Intl.NumberFormat` for numbers and currency
- Use `Intl.DateTimeFormat` for dates
- Set `dir="auto"` or `dir="rtl"` on root elements

### 7. RTL-Aware Components
- Carousels, sliders, and progress bars must reverse direction in RTL
- Swipe gestures must reverse in RTL
- Charts and graphs with directional axes must flip

### 8. Testing
- Always test with `dir="rtl"` on the root element
- Verify with actual RTL content, not just flipped LTR

## Automated RTL Auditing

For automated RTL violation detection and fixing, use [rtlify-ai](https://github.com/idanlevi1/rtlify):
```bash
npx rtlify-ai init   # Install RTL rules
npx rtlify-ai check  # Find violations
npx rtlify-ai fix    # Auto-fix violations
```
