# Minimal Lite Release - Status Report

**Date**: 2025-01-18  
**Status**: ✅ **Phases 1-4 Complete**

## Overview

The Minimal Lite Release provides a stripped-down Octave runtime with only essential libraries, suitable for bundling with desktop applications. All core phases have been completed.

## ✅ Completed Phases

### Phase 1: Minimal Build Configuration ✅

**Status**: Complete

**Deliverables**:
- ✅ `scripts/build/configure-lite.sh` - Minimal build configuration script
- ✅ Configuration flags for lite build (no GUI, no docs, no Java)
- ✅ OpenBLAS integration for performance

**Features**:
- Minimal runtime with only essential components
- Optimized for size and performance
- Cross-platform build support

### Phase 2: Installer Creation ✅

**Status**: Complete

**Deliverables**:
- ✅ Windows Installer: `installers/windows/nexus-lite.nsi` (NSIS script)
- ✅ Windows Build: `installers/windows/build-installer.bat`
- ✅ macOS Installer: `installers/macos/build-pkg.sh` (pkgbuild)
- ✅ Linux Debian: `installers/linux/debian/build-deb.sh`
- ✅ Linux RPM: `installers/linux/rpm/build-rpm.sh` + `nexus-lite.spec`
- ✅ Linux AppImage: `installers/linux/appimage/build-appimage.sh`

**Features**:
- Cross-platform installer support
- Automatic dependency bundling
- Uninstaller support (Windows)
- Package management integration (Linux)

### Phase 3: Library Bundling System ✅

**Status**: Complete

**Deliverables**:
- ✅ `scripts/build/analyze-dependencies.sh` - Dependency analysis tool
- ✅ `scripts/build/bundle-libs.sh` - Library bundling script
- ✅ `scripts/build/create-bundle.sh` - Modular bundle creator
- ✅ `scripts/build/bundle/manifest.json` - Library manifest
- ✅ `scripts/build/projects/create-project-bundle.sh` - Project-specific bundles

**Features**:
- Modular library architecture
- Dependency resolution
- Custom bundle creation per project
- Library manifest system

### Phase 4: Compiler Integration ✅

**Status**: Complete

**Deliverables**:
- ✅ C++ Embedding: `examples/embed-cpp/main.cpp` + `CMakeLists.txt` + `build.sh`
- ✅ Python Wrapper: `examples/embed-python/wrapper.py`
- ✅ Cross-platform build system documentation
- ✅ Docker support: `docker/Dockerfile.linux`

**Features**:
- Standalone executable examples
- Python integration
- Cross-platform builds
- Containerized builds

## 📦 Bundle Architecture

### Core Libraries

- **Core Runtime**: Essential Octave core components (~50MB)
- **Table Support**: MATLAB-compatible table data type (~2.5MB)
- **Signal Processing**: Signal analysis functions (~1.8MB)
- **Unit Test Framework**: MATLAB unittest compatibility (~1MB)

### Modular System

Libraries can be included/excluded via manifest:
```json
{
  "libraries": {
    "core": {...},
    "table": {...},
    "signal": {...},
    "unittest": {...}
  }
}
```

## 🚀 Usage Examples

### Create Project Bundle

```bash
./scripts/build/projects/create-project-bundle.sh \
  --project myproject \
  --libs core,table \
  --platform windows \
  --output myproject-installer
```

### Build Lite Runtime

```bash
./scripts/build/configure-lite.sh
make -j$(nproc)
make install
```

### Create Installer

**Windows**:
```bash
cd installers/windows
./build-installer.bat
```

**macOS**:
```bash
cd installers/macos
./build-pkg.sh
```

**Linux**:
```bash
cd installers/linux/debian
./build-deb.sh
```

## 📊 Statistics

- **Total Scripts Created**: 15+
- **Platforms Supported**: Windows, macOS, Linux (Debian/RPM/AppImage)
- **Bundle Sizes**: 50-200MB (depending on included libraries)
- **Build Time**: ~30-60 minutes (depending on platform)
