# Project TM Auto-Population Fix

**Date**: 2025-10-10  
**Issue**: Segments not being added to Project TM automatically  
**Status**: ✅ FIXED

## Problem

User reported that:
1. **TM matches not appearing automatically** - Auto-search was triggering, but no matches because...
2. **Segments not saved to Project TM** - Translations weren't being added to TM automatically
3. **Project TM appearing disabled** - Actually enabled, but empty so no matches

**Root Cause**: The `save_current_segment()` and `save_grid_editor_segment()` methods were updating segment data but **not adding translations to the Project TM**.

## How Project TM Should Work

In professional CAT tools, the Project TM is automatically populated as you translate:

1. **User translates segment** → Types translation, sets status to "Translated" or "Approved"
2. **User saves segment** → Presses Ctrl+Enter or clicks Next
3. **Segment saved to Project TM** → Source + Target pair added automatically
4. **Future segments** → TM search finds matches from previously translated segments

**Example workflow:**
```
Segment 1: "Hello world" → Translate → "Hallo wereld" → Save → Added to Project TM ✓
Segment 2: "Hello there" → Auto-search → Finds 95% match "Hello world" from Segment 1 ✓
```

## Solution Implemented

### Fix 1: Add to Project TM in `save_current_segment()`

**File**: `Supervertaler_v3.0.0-beta_CAT.py`  
**Line**: ~7705

**Before:**
```python
# Update segment
if target != self.current_segment.target or status != self.current_segment.status:
    self.current_segment.target = target
    self.current_segment.status = status
    self.current_segment.modified = True
    self.current_segment.modified_at = datetime.now().isoformat()
    self.modified = True
    
    # Update grid
    self.update_segment_in_grid(self.current_segment)
    self.update_progress()
```

**After:**
```python
# Update segment
if target != self.current_segment.target or status != self.current_segment.status:
    self.current_segment.target = target
    self.current_segment.status = status
    self.current_segment.modified = True
    self.current_segment.modified_at = datetime.now().isoformat()
    self.modified = True
    
    # Add to Project TM if translated or approved and has content
    if status in ['translated', 'approved'] and target:
        self.tm_database.add_to_project_tm(self.current_segment.source, target)
        self.log(f"✓ Added to Project TM: {self.current_segment.source[:50]}...")
    
    # Update grid
    self.update_segment_in_grid(self.current_segment)
    self.update_progress()
```

### Fix 2: Add to Project TM in `save_grid_editor_segment()`

**File**: `Supervertaler_v3.0.0-beta_CAT.py`  
**Line**: ~2105

**Before:**
```python
def save_grid_editor_segment(self):
    if hasattr(self, 'current_segment') and self.current_segment:
        target = self.grid_target_text.get('1.0', 'end-1c').strip()
        self.current_segment.target = target
        self.current_segment.status = self.grid_status_var.get()
        self.current_segment.modified = True
        self.modified = True
        self.update_progress()
        # Update the grid row
        if self.current_row_index >= 0:
            self.update_grid_row(self.current_row_index)
        self.log(f"✓ Segment #{self.current_segment.id} saved")
```

**After:**
```python
def save_grid_editor_segment(self):
    if hasattr(self, 'current_segment') and self.current_segment:
        target = self.grid_target_text.get('1.0', 'end-1c').strip()
        status = self.grid_status_var.get()
        
        self.current_segment.target = target
        self.current_segment.status = status
        self.current_segment.modified = True
        self.modified = True
        
        # Add to Project TM if translated or approved and has content
        if status in ['translated', 'approved'] and target:
            self.tm_database.add_to_project_tm(self.current_segment.source, target)
            self.log(f"✓ Added to Project TM: {self.current_segment.source[:50]}...")
        
        self.update_progress()
        # Update the grid row
        if self.current_row_index >= 0:
            self.update_grid_row(self.current_row_index)
        self.log(f"✓ Segment #{self.current_segment.id} saved")
```

## Behavior After Fix

### When You Save a Segment:

**List/Document Mode** (Ctrl+Enter):
1. Target text and status captured
2. Segment updated in memory
3. **If status = "Translated" or "Approved" and target exists:**
   - ✅ Added to Project TM
   - ✅ Log message: "✓ Added to Project TM: [source text]..."
4. Grid updated, progress updated

**Grid Mode** (Save button or Next):
1. Grid editor values captured
2. Segment updated in memory
3. **If status = "Translated" or "Approved" and target exists:**
   - ✅ Added to Project TM
   - ✅ Log message: "✓ Added to Project TM: [source text]..."
4. Grid row updated, progress updated

### When Auto-Search Runs:

**2 seconds after selecting a segment:**
1. Auto-search timer triggers
2. Search queries **all enabled TMs** (including Project TM)
3. Finds matches from:
   - ✅ Project TM (your previously translated segments)
   - ✅ Big Mama TM (if loaded)
   - ✅ Custom TMs (if loaded and enabled)
4. Displays matches with TM source: `[Project TM]`, `[Big Mama]`, etc.

## Example Workflow

**Translate first segment:**
```
Segment 1: "The pivot point is critical"
↓ Type translation
Target: "Het draaipunt is cruciaal"
↓ Set status to "Translated"
↓ Press Ctrl+Enter (save)
✓ Added to Project TM: The pivot point is critical...
✓ Segment #1 saved
```

**Navigate to second segment:**
```
Segment 2: "The pivot point must be adjusted"
↓ Wait 2 seconds (auto-search triggers)
🔍 Searching All Active TMs (min 75% match)...
✓ Found 1 TM matches

Match Results:
92% | Het draaipunt moet worden aangepast [Project TM]
     (from segment 1 - fuzzy match!)
```

**Apply match or edit:**
```
Double-click match → Inserts into target
Edit as needed
Set status to "Translated"
Press Ctrl+Enter
✓ Added to Project TM: The pivot point must be adjusted...
```

**Continue translating:**
```
Every saved translation → Added to Project TM
Every new segment → Auto-searches Project TM
Matches accumulate → Better suggestions over time
```

## Conditions for Adding to Project TM

**Only added when ALL conditions met:**

1. ✅ **Segment saved** - User presses Ctrl+Enter or clicks Save/Next
2. ✅ **Target has content** - Not empty or whitespace-only
3. ✅ **Status is confirmed** - Status = "Translated" or "Approved"
   - ❌ Status = "Draft" → NOT added (incomplete translation)
   - ❌ Status = "Not Started" → NOT added (no translation)

**Why check status?**

Professional CAT tools only add "confirmed" translations to TM:
- **Draft** = Work in progress, not ready for reuse
- **Translated** = Finished, ready for review, can be reused
- **Approved** = Reviewed and confirmed, definitely reuse

## Project TM Persistence

**When saved to project file:**
```json
{
  "tm_database": {
    "project_tm": {
      "name": "Project TM",
      "enabled": true,
      "entries": {
        "The pivot point is critical": "Het draaipunt is cruciaal",
        "The pivot point must be adjusted": "Het draaipunt moet worden aangepast",
        ...
      },
      "metadata": {
        "source_lang": "en",
        "target_lang": "nl"
      }
    }
  }
}
```

**When loaded:**
- All previous translations restored
- Available immediately for TM search
- Grows as you translate more

## Benefits

### Before Fix:
❌ Project TM always empty  
❌ No matches from previously translated segments  
❌ Had to manually search or retype similar translations  
❌ Auto-search found nothing useful  

### After Fix:
✅ Project TM auto-populated as you translate  
✅ Future segments benefit from past translations  
✅ Auto-search finds matches from your own work  
✅ Professional CAT tool behavior  

## User Impact

**Translation workflow improved:**

1. **Start project** → Project TM empty, no matches
2. **Translate 10 segments** → Project TM has 10 entries
3. **Segment 11 is similar to segment 3** → Auto-search finds 95% match!
4. **Apply match, minor edit** → Faster translation
5. **Save segment 11** → Now 11 entries in Project TM
6. **Continue...** → TM grows, suggestions improve

**Time savings example:**

| Segment | Without Project TM | With Project TM |
|---------|-------------------|-----------------|
| 1-10    | Translate from scratch | Translate from scratch |
| 11      | Translate from scratch | 95% match → edit 5% |
| 12      | Translate from scratch | 88% match → edit 12% |
| 13      | Translate from scratch | 100% match → press Enter! |

**Result**: After initial 10 segments, translation speed increases significantly!

2. Translate first segment: "Hello world" → "Hallo wereld"
3. Set status to "Translated"
4. Press Ctrl+Enter (save)
5. Check log: Should see "✓ Added to Project TM: Hello world..."
6. Navigate to second segment: "Hello there"
7. Wait 2 seconds
8. Check TM matches: Should see fuzzy match from "Hello world" with `[Project TM]` label
9. Open TM Manager → View Project TM
10. Should see 1 entry: "Hello world" → "Hallo wereld"

✅ All steps should work as described!
