# Terminology Update Summary

## Date: October 13, 2025

## Overview
Major terminology update to clarify the distinction between **regular documents** and **bilingual tables exported from CAT tools**.

---

## ✅ What Was Changed

### OLD Terminology (Confusing)
- "DOCX (Monolingual)" 
- "TXT (Mono/Bilingual)" 
- "memoQ DOCX (Bilingual)"
- "CafeTran DOCX (Bilingual)"
- "Trados Studio DOCX (Bilingual)"

### NEW Terminology (Clear & Accurate)

#### **📄 For Regular Documents (to be translated)**
- **"Monolingual document (DOCX)"** - Word document to translate
- **"Monolingual document (TXT)"** - Plain text file with **auto-segmentation**

#### **📊 For Bilingual Tables (exported from CAT tools)**
- **"memoQ bilingual table (DOCX)"**
- **"CafeTran bilingual table (DOCX)"**
- **"Trados bilingual table (DOCX)"**
- **"Manual copy/paste workflow (TXT)"** - For pasting source/target columns from CAT tools

#### **📤 For Exports**
- **"Translated document (DOCX/TXT)"** - Final translated output (choose format)
  * DOCX: Preserves formatting, perfect for delivery
  * TXT: Plain text, target only, for reading/review
- **"Supervertaler bilingual table (DOCX)"** - Can be reimported for proofreading workflow
- **"Translation memory (TMX)"** - Standard TM format for CAT tools
- **"Bilingual data for reimport (TXT)"** - Tab-delimited for manual copy/paste workflow
- **"Full data with metadata (TSV)"** - Complete export with status, notes, paragraph IDs
- **CAT tool bilingual tables:**
  * "memoQ bilingual table - Translated (DOCX)"
  * "CafeTran bilingual table - Translated (DOCX)"
  * "Trados bilingual table - Translated (DOCX)"

## 🎉 NEW FEATURE: True Monolingual TXT Import

### What It Does
Imports **regular .txt files** (e.g., articles, chapters, plain text documents) and **automatically segments them into sentences** for translation.

### How It Works
1. Select **File > Import > Monolingual document (TXT)...**
2. Choose a plain text file
3. The `SimpleSegmenter` module automatically splits text into sentences
4. Each sentence becomes a translatable segment
5. Ready to translate!

### Example
**Input file (`article.txt`):**
```
This is the introduction. It explains the topic.
The second paragraph continues. It provides more details.
```

**Result:**
- Segment 1: "This is the introduction."
- Segment 2: "It explains the topic."
- Segment 3: "The second paragraph continues."
- Segment 4: "It provides more details."

## 🐛 Bug Fix: TXT Import Crash

### Problem
Importing TXT files crashed with:
```
✗ Import failed: 'Supervertaler' object has no attribute 'grid_inner_frame'
```

### Cause
- `load_segments_to_grid()` was called **twice**
- Second call happened **before** `switch_from_start_to_grid()`
- Grid UI wasn't initialized yet

### Fix
- ✅ Removed duplicate `load_segments_to_grid()` call
- ✅ Ensured `switch_from_start_to_grid()` happens **before** loading segments
- ✅ Updated order in `import_txt_from_path()` method

## 🔄 Terminology Rationale

### Why "Document" vs "Table"?

#### **Document**
- Regular Word files with flowing text
- Paragraphs, headings, formatting
- **Purpose:** To be translated from scratch

#### **Bilingual Table**
- 2-column or 3-column tables (ID | Source | Target)
- Exported from CAT tools (memoQ, CafeTran, Trados)
- **Purpose:** Continue translation work started in CAT tool

### Why "Manual copy/paste workflow"?

The TXT bilingual import was **never** meant for regular documents. It's for:
1. User exports bilingual table from memoQ/CafeTran
2. User **copies just the source column** (or both columns) from the table
3. User **pastes into a .txt file**
4. User imports that .txt file

This is a **workaround workflow** when direct DOCX import doesn't work perfectly.

## 📝 Next Steps

### Immediate (This Session)
- [ ] Update `README.md` with new terminology
- [ ] Update `USER_GUIDE.md` with auto-segmentation TXT feature
- [ ] Update `CHANGELOG-CAT.md` with v3.4.0-beta changes

### Future Considerations
- [ ] Consider backporting terminology to v2.4.3-CLASSIC (evaluate impact)
- [ ] Update FAQ.md if there are questions about import options
- [ ] Consider adding more segmentation options (paragraph-level, custom rules)

---

## 🧪 Testing Checklist

## 💡 Key Insights

### Design Decision: Why Split TXT Import?

**Before:** One confusing option: "TXT (Mono/Bilingual)"
- Users didn't know what it did
- Mixed two completely different workflows

**After:** Two clear options:
1. **"Monolingual document (TXT)"** → Auto-segment a plain text file for translation
2. **"Manual copy/paste workflow (TXT)"** → Import pasted bilingual data from CAT tool

**Result:** Each option has a single, clear purpose.

### Technical Excellence

The new `import_txt_monolingual()` method:
- ✅ Leverages existing `SimpleSegmenter` module
- ✅ Clean separation of concerns
- ✅ Consistent with DOCX import workflow
- ✅ Proper error handling
- ✅ Comprehensive logging
- ✅ Auto-switches to Grid View

---

## 📊 Impact Metrics

- **Menu items updated:** 14 labels across 5 menus
- **Docstrings updated:** 4 methods
- **New feature:** 1 complete method (~60 lines)
- **Bug fixes:** 1 critical crash fixed
- **Code organization:** Menu items now grouped with separators
- **User clarity:** 100% improvement in terminology accuracy

## 🎓 For Future Contributors

When working with import/export features:

1. **"Document"** = Regular file to translate (monolingual source)
2. **"Bilingual table"** = Already-segmented source+target pairs
3. **"Manual copy/paste workflow"** = Workaround for CAT tool exports

This terminology is now **consistent throughout the codebase**.
