# LangToLang v1.5.1 - Critical Bug Fixes

## 🐛 Bugs Fixed

---

### Bug #1: Empty Window on Startup

**Problem:**  
When LangToLang launches, an empty window appears with no content.

**Root Cause:**  
The `WindowGroup` in `LangToLangApp.swift` was creating a visible window even though the app is menu-bar only.

**Solution:**  
Changed from `WindowGroup` to `Settings` scene type, which doesn't create a visible window.

**File:** `LangOverApp.swift`

**Before:**
```swift
var body: some Scene {
    WindowGroup {
        EmptyView()
            .frame(width: 0, height: 0)
            .hidden()
    }
}
```

**After:**
```swift
var body: some Scene {
    Settings {
        EmptyView()
    }
}
```

**Result:** ✅ No empty window appears on launch

### Bug #2: Letter "W" Not Converting Correctly

**Problem:**  
When converting from Hebrew to English, the letter 'w' doesn't convert properly.

**Examples of the bug:**
```
׳armth  →  should be: warmth
׳ith    →  should be: with  
׳ןאי    →  should be: with
```

**Root Cause:**  
The Hebrew keyboard produces different apostrophe characters depending on context:
- Regular apostrophe: `'` (U+0027)
- Right single quotation mark: `'` (U+2019)  
- Geresh: `׳` (U+05F3)

Only the regular apostrophe was mapped to 'w', so the other variations weren't converting.

**Solution:**  
Added all three apostrophe variants to the Hebrew→English mapping.

**File:** `LayoutConverter.swift`

**Before:**
```swift
let mapping: [Character: Character] = [
    "/": "q", "'": "w", "ק": "e", ...
```

**After:**
```swift
let mapping: [Character: Character] = [
    "/": "q", 
    "'": "w",   // Regular apostrophe
    "'": "w",   // Right single quotation mark  
    "׳": "w",   // Geresh (Hebrew punctuation)
    "ק": "e", ...
```

**Additional Fix:**  
Also corrected the "b" mapping:
- English `b` → Hebrew `נ` (nun, not final nun `ן`)

**Test Cases:**
```
Input:     ׳armth
Expected:  warmth
Result:    ✅ warmth

Input:     ׳ith
Expected:  with
Result:    ✅ with

Input:     ׳ןאי
Expected:  with  
Result:    ✅ with
```

## 📋 Testing Instructions

### Test #1: Empty Window
1. Quit LangToLang completely
2. Launch LangToLang
3. ✅ Verify: No empty window appears
4. ✅ Verify: Only menu bar icon appears
5. ✅ Verify: App is running (click menu bar icon)

### Test #2: Letter W Conversion
1. Open any text editor
2. Switch to Hebrew keyboard
3. Type: `'armth` (using the apostrophe key where 'w' would be)
4. Select the text
5. Press hotkey (Ctrl+Shift+Space)
6. ✅ Verify: Text converts to `warmth`

**Additional test cases:**
```
Hebrew Input  →  Expected English Output
─────────────────────────────────────────
'ןאי          →  with
'שרצאי        →  warmth  
איק צשןמ      →  the main
```

## 🔧 Technical Details

### Character Code Points

**Apostrophe variants that map to 'w':**
1. `'` - U+0027 (APOSTROPHE) - Standard ASCII apostrophe
2. `'` - U+2019 (RIGHT SINGLE QUOTATION MARK) - Typographic apostrophe
3. `׳` - U+05F3 (HEBREW PUNCTUATION GERESH) - Hebrew punctuation mark

### Why Multiple Apostrophes?

Different keyboards and input methods produce different Unicode characters for the "apostrophe" key:
- macOS Hebrew keyboard can produce any of these depending on context
- Some text editors auto-replace straight quotes with curly quotes
- Hebrew typography uses geresh for certain purposes

By mapping all three variants, we ensure the conversion works regardless of which character the system produces.
