# PyInstallerEx
Enhanced PyInstaller packaging tool that creates single-file executable programs with installation capabilities

## 🎯 Project Overview

PyInstallerEx is an enhanced packaging tool based on PyInstaller that can package Python applications into single-file executable programs with installation capabilities. Unlike traditional PyInstaller which creates standalone executable files, the installer executable files created by PyInstallerEx have the following characteristics:

- **Extract on first run**: Applications are extracted to a temporary directory
- **Reuse installed versions**: Subsequent runs use already extracted versions
- **Automatic cleanup**: Intelligent management of temporary files

### 🔧 Environment Requirements
- Python >= 2.7
- PyInstaller >= 3.2.1
- Go >= 1.21 (for building launchers)

### ⚙️ How It Works
1. **PyInstaller Packaging**: Use PyInstaller's `--onedir` mode to create a complete application directory
2. **Configuration Processing**: Apply user configurations and generate metadata
3. **Compression**: Compress the application directory into a ZIP file
4. **Binary Merging**: Merge the platform-specific launcher binary with the ZIP file
5. **Final Executable**: Create a single executable file that handles extraction and execution

## ✅ Completed Features

### 1. Core Packaging Features
- ✅ **PyInstaller Integration**: Use `--onedir` mode to create complete application directories
- ✅ **Configuration System**: JSON format configuration file support
- ✅ **ZIP Compression**: Compress application directories into ZIP files
- ✅ **Binary Merging**: Merge Go launcher with ZIP file into final executable file

### 2. Go Launcher Implementation
- ✅ **Cross-platform Support**: Windows, Linux x86, Linux ARM
- ✅ **Smart Installation**: Automatically extract on first run, reuse installed versions on subsequent runs
- ✅ **Configuration Parsing**: Read and process configuration information from executable files
- ✅ **Temporary Directory Management**: Automatic management of temporary files and cleanup

### 3. Project Structure Improvement
- ✅ **Modular Design**: Clear code organization structure
- ✅ **Error Handling**: Complete exception handling and logging
- ✅ **Build Scripts**: Automated compilation and testing scripts
- ✅ **Complete Documentation**: Detailed usage instructions and API documentation

## 🌟 New Features

### 1. Enhanced Cache Management
- ✅ **Smart Cache Reuse**: Check if the application is already installed before extracting (based on `ex_{filename}_{md5}` directory pattern)
- ✅ **Automatic Old Cache Cleanup**: Before extracting, search and remove old directories with the same filename prefix (`ex_{filename}_*`)
- ✅ **Cache Isolation**: Ensure only one version of the application is kept in the temporary directory

### 2. Improved Configuration Handling
- ✅ **Embedded Configuration Reading**: Read configuration from executable files for better portability
- ✅ **Flexible Configuration Override**: Command-line parameters override configuration files which override embedded defaults

## 🛠 Development

### Build from Source

```bash
git clone <repository>
cd PyInstallerEx-master

# Development test installation
pip install -e .

# Build package using traditional setup.py
python setup.py sdist bdist_wheel

# Uninstall old version
pip uninstall pyinstallerex

# Test installation
pip install dist/pyinstallerex-0.1.6-py2-none-any.whl

# Test packaging
python -m PyInstallerEx test/test_script.py 

# Build Go launcher
./build_launchers.sh
```

### Testing

```bash
# Test using included test script
python -m PyInstallerEx test/test_script.py --cfg test/test_config.json

# Or from test directory
cd test
python -m PyInstallerEx test_script.py --cfg test_config.json
```

## 📦 Installation

Install the latest version from PyPI:
```bash
pip install pyinstallerex
```

## 🚀 Usage

Basic usage:
```bash
# Using pyinstallerex command
pyinstallerex your_script.py

# Using PyInstallerEx command
PyInstallerEx your_script.py

# Using Python -m method (recommended)
python -m PyInstallerEx your_script.py
```

Using configuration file:
```bash
pyinstallerex your_script.py --cfg your_config.json
```
