# Pytopspeed Modernized

A modernized Python library for converting Clarion TopSpeed database files (.phd, .mod, .tps, .phz) to SQLite databases and back.

[![Python 3.8+](https://img.shields.io/badge/python-3.8+-blue.svg)](https://www.python.org/downloads/)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)
[![Tests](https://img.shields.io/badge/tests-88%20passing-brightgreen.svg)](tests/)

## 🚀 Features

- **Multi-format Support**: Convert .phd, .mod, .tps, and .phz files
- **Combined Conversion**: Merge multiple TopSpeed files into a single SQLite database
- **Reverse Conversion**: Convert SQLite databases back to TopSpeed files
- **PHZ Support**: Handle zip archives containing TopSpeed files
- **Progress Tracking**: Real-time progress reporting and detailed logging
- **Data Integrity**: Preserve all data types and relationships
- **CLI Interface**: Easy-to-use command-line tools
- **Python API**: Programmatic access to all functionality
- **Comprehensive Testing**: 88+ unit tests and integration tests

## 📋 Supported File Formats

| Format | Description | Support |
|--------|-------------|---------|
| `.phd` | Clarion TopSpeed database files | ✅ Full |
| `.mod` | Clarion TopSpeed model files | ✅ Full |
| `.tps` | Clarion TopSpeed files | ✅ Full |
| `.phz` | Zip archives containing TopSpeed files | ✅ Full |

## 🛠️ Quick Start

### Installation

```bash
# Clone the repository
git clone <repository-url>
cd phdwin_reader

# Create conda environment
conda create -n phdwin_reader python=3.11
conda activate phdwin_reader

# Install dependencies
pip install -r requirements.txt
```

### Basic Usage

```bash
# Convert a single .phd file to SQLite
python pytopspeed.py convert assets/TxWells.PHD output.sqlite

# Convert multiple files to a combined database
python pytopspeed.py convert assets/TxWells.PHD assets/TxWells.mod combined.sqlite

# Convert a .phz file (zip archive)
python pytopspeed.py convert assets/TxWells.phz output.sqlite

# List contents of a .phz file
python pytopspeed.py list assets/TxWells.phz

# Convert SQLite back to TopSpeed files
python pytopspeed.py reverse input.sqlite output_directory/
```

### Python API

```python
from converter.sqlite_converter import SqliteConverter

# Single file conversion
converter = SqliteConverter()
results = converter.convert('input.phd', 'output.sqlite')

# Multiple file conversion
results = converter.convert_multiple(['file1.phd', 'file2.mod'], 'combined.sqlite')

# PHZ file conversion
from converter.phz_converter import PhzConverter
phz_converter = PhzConverter()
results = phz_converter.convert_phz('input.phz', 'output.sqlite')
```

## 📊 Performance

Based on testing with `TxWells.PHD` and `TxWells.mod`:

- **Single file conversion**: ~1,300 records/second
- **Combined conversion**: ~1,650 records/second  
- **Reverse conversion**: ~50,000 records/second
- **Memory efficient**: Configurable batch processing
- **Progress tracking**: Real-time progress reporting

## 🔧 Command Line Interface

### Convert Command

```bash
python pytopspeed.py convert [OPTIONS] INPUT_FILES... OUTPUT_FILE
```

**Options:**
- `--batch-size BATCH_SIZE` - Number of records to process in each batch (default: 1000)
- `-v, --verbose` - Enable verbose logging
- `-q, --quiet` - Suppress progress output

### Reverse Command

```bash
python pytopspeed.py reverse [OPTIONS] INPUT_FILE OUTPUT_DIRECTORY
```

### List Command

```bash
python pytopspeed.py list [OPTIONS] PHZ_FILE
```

- ✅ **Integration tests** - End-to-end conversion testing
- ✅ **Performance tests** - Benchmarking and optimization
- ✅ **Error handling tests** - Robust error handling validation

## 📖 Examples

Working examples are available in the `examples/` directory:

- **Basic conversion** - Single file conversion
- **Combined conversion** - Multiple file conversion
- **PHZ handling** - Zip archive processing
- **Reverse conversion** - SQLite to TopSpeed
- **Round-trip conversion** - Complete conversion cycle
- **Custom progress tracking** - Advanced progress monitoring
- **Error handling** - Comprehensive error handling patterns

## 🏗️ Architecture

```
TopSpeed Files → Parser → Schema Mapper → SQLite Converter → SQLite Database
     ↓              ↓           ↓              ↓
   .phd/.mod    Modernized   Type Mapping   Data Migration
   .tps/.phz    pytopspeed   Field Names    Batch Processing
```

### Key Components

- **TopSpeed Parser** - Modernized parser for reading TopSpeed files
- **Schema Mapper** - Maps TopSpeed schemas to SQLite
- **SQLite Converter** - Handles data migration and conversion
- **PHZ Converter** - Processes zip archives containing TopSpeed files
- **Reverse Converter** - Converts SQLite back to TopSpeed files
- **CLI Interface** - Command-line tools for easy usage

## 🔄 Data Type Conversion

| TopSpeed Type | SQLite Type | Notes |
|---------------|-------------|-------|
| BYTE | INTEGER | 8-bit unsigned integer |
| SHORT | INTEGER | 16-bit signed integer |
| LONG | INTEGER | 32-bit signed integer |
| DATE | TEXT | Format: YYYY-MM-DD |
| TIME | TEXT | Format: HH:MM:SS |
| STRING | TEXT | Variable length text |
| DECIMAL | REAL | Floating point number |
| MEMO | BLOB | Binary large object |
| BLOB | BLOB | Binary large object |

## 🎯 Key Features

### Table Name Prefixing

When converting multiple files, tables are automatically prefixed to avoid conflicts:

- **.phd files** → `phd_` prefix (e.g., `phd_OWNER`, `phd_CLASS`)
- **.mod files** → `mod_` prefix (e.g., `mod_DEPRECIATION`, `mod_MODID`)
- **.tps files** → `tps_` prefix
- **Other files** → `file_N_` prefix

### Column Name Sanitization

Column names are automatically sanitized for SQLite compatibility:

- **Prefix removal**: `TIT:PROJ_DESCR` → `PROJ_DESCR`
- **Special characters**: `.` → `_`
- **Numeric prefixes**: `123FIELD` → `_123FIELD`
- **Reserved words**: `ORDER` → `ORDER_TABLE`

### Error Handling

- **Graceful degradation** - Continue processing despite individual table errors
- **Detailed logging** - Comprehensive error reporting and debugging information
- **Data preservation** - Ensure data integrity even with parsing issues
- **Recovery mechanisms** - Automatic handling of common issues
