# rtl-right-to-left-i18n-cursorrules-prompt-file

A Cursor rule that pushes the agent toward logical CSS and Tailwind utilities instead of left/right. Useful when the app has to run in Arabic, Hebrew, Persian or Urdu.

## What it does

The rule lays out eight areas. Logical CSS properties replace physical ones: `margin-inline-start` over `margin-left`, `inset-inline-start` over `left`. Tailwind gets the same treatment — `ms-4`, `me-4`, `ps-4`, `pe-4`, `start-0`, `end-0`. React Native has its own list: `paddingStart` instead of `paddingLeft`.

Then come bidirectional text and icons. Mixed-script strings should sit inside `<bdi>`, and directional icons — arrows, chevrons, back buttons — flip in RTL. Home, settings and search stay put. Strings should not be hardcoded; numbers and dates go through `Intl.NumberFormat` and `Intl.DateTimeFormat`, with `dir="auto"` or `dir="rtl"` on the root. Carousels, sliders, progress bars and swipe gestures reverse direction.

For auditing the rule points at `rtlify-ai`: `npx rtlify-ai init` installs the rules, `npx rtlify-ai check` finds violations, `npx rtlify-ai fix` repairs them. Testing advice is blunt — use real RTL content, not a mirrored LTR page, or bidirectional bugs stay hidden. The file lives at `.cursor/rules/` with an `.mdc` extension, so outside Cursor it does nothing.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/rtl-right-to-left-i18n-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/rtl-right-to-left-i18n-cursorrules-prompt-file.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/rtl-right-to-left-i18n-cursorrules-prompt-file.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/rtl-right-to-left-i18n-cursorrules-prompt-file.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/rtl-right-to-left-i18n-cursorrules-prompt-file.md`

## When to use it
- convert physical CSS properties to logical ones without editing every file by hand
- catch Tailwind `ml-` and `pr-` classes that break an RTL layout
- wrap user names in `<bdi>` so mixed-script text stops jumping
- reverse carousels, sliders and swipe gestures when the direction flips
- flip arrows and chevrons while leaving search and settings icons alone

## Example prompts
- Audit this component for RTL and swap physical properties for logical ones
- Fix the Tailwind classes in `src/components/Card.tsx` for RTL
- Run `npx rtlify-ai check` and fix what it reports

# 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
```
````

The third-party file has ended. Everything between the 585a031545fcf87f tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
