# Install Script Updates - Summary of Changes

## Files Modified
- `install.sh` - Main installation script

## Files Created
- `INSTALL_METHOD_GUIDE.md` - Comprehensive documentation
- `QUICK_START.txt` - Quick reference guide
- `CHANGES_SUMMARY.md` - This file

## Key Additions to install.sh

### 1. Package Source Variable (Line 4-6)
```bash
# Source location for pre-built Debian packages (can be local or network share)
# Set this variable to the path containing .deb files, or leave empty to build from source
DEB_PACKAGES_SOURCE="/mnt/nas/Projects/Jak/debian-pkg/build/debs"
```

**Purpose:** Configurable location for pre-built .deb packages
**Default:** `/mnt/nas/Projects/Jak/debian-pkg/build/debs`
**Can be modified to:** Any local path or network share with .deb files

### 2. clean_existing_hyprland() Function (Lines 123-160)
**Purpose:** Remove conflicting installations before installing from packages

**Operations:**
- Removes all .deb packages using `apt-get remove`
- Deletes source-built binaries from /usr/bin and /usr/local/bin
- Removes development files from /usr/local/include and /usr/local/lib
- Updates library cache with `ldconfig`

**Packages Cleaned:**
- hyprland, hyprutils, hyprgraphics, hyprcursor, hyprtoolkit
- hyprland-guiutils, hyprwire, aquamarine, hypridle, hyprlock
- hyprpolkitagent, hyprpicker, xdg-desktop-portal-hyprland, hyprland-plugins

**Binaries Cleaned:**
- /usr/local/bin/Hyprland, /usr/local/bin/hyprland
- /usr/bin/Hyprland, /usr/bin/hyprland

**Development Files Cleaned:**
- /usr/local/include/hyprland*
- /usr/local/lib/libhypr*
- /usr/local/lib/libaquamarine*
- /usr/local/lib/libypr*

### 3. install_from_packages() Function (Lines 162-197)
**Purpose:** Install Hyprland from pre-built .deb packages

**Steps:**
1. Validate DEB_PACKAGES_SOURCE exists
2. Count available .deb files
3. Call clean_existing_hyprland() for cleanup
4. Update package cache with `apt-get update`
5. Install all .deb files with `dpkg -i`
6. Fix dependencies with `apt-get install -f -y`

### 4. Build Method Selection (Lines 206-231)
**Purpose:** Allow user to choose between source build and package installation

**Logic:**
- Detects if packages are available at DEB_PACKAGES_SOURCE
- If yes, prompts user with whiptail dialog
  - YES: Install from pre-built packages
  - NO: Build from source
- If no packages found, defaults to source build

**User Prompts:**
- "Build Method" dialog shows package location and options
- "Proceed with Installation?" dialog shows selected method and instructions

### 5. Installation Flow Modification (Lines 429-490)
**Purpose:** Execute selected build method with proper conditional logic

**Changes:**
- Added if/else condition checking `build_method` variable
- If "packages": Calls install_from_packages()
- If "source": Executes original build scripts

**Original Behavior:** Always builds from source
**New Behavior:** Offers choice, defaults to source if packages unavailable

## Benefits

### For Users
- **Faster Installation:** 5-10 minutes vs 1-2 hours with pre-built packages
- **Simpler Setup:** No build tools required for package installation
- **Flexibility:** Can choose between speed (packages) or latest code (source)
- **Safety:** Automatic cleanup prevents conflicts between methods
- **Testing Ready:** Can quickly test pre-built packages on shared network

### For Testing/Development
- **Network Share Support:** Can test on NAS without compiling
- **Version Control:** Easy to test different package versions
- **Quick Iteration:** Fast install/uninstall cycles for testing
- **Shared Resources:** Multiple users can share pre-built packages

## Configuration

### Default Setup (Current)
```bash
DEB_PACKAGES_SOURCE="/mnt/nas/Projects/Jak/debian-pkg/build/debs"
```

### To Disable Package Installation (Always Source)
```bash
DEB_PACKAGES_SOURCE=""
```

### To Use Different Package Location
```bash
DEB_PACKAGES_SOURCE="/path/to/your/packages"
```

## Usage Examples

### Quick Install from Packages
```bash
./install.sh
# Select YES when prompted
# ~5-10 minutes
```

### Build from Source
```bash
./install.sh
# Select NO when prompted
# ~1-2 hours
```

### Force Package Location
```bash
DEB_PACKAGES_SOURCE="/custom/path" ./install.sh
```

## Backward Compatibility

✓ **Fully backward compatible**
- If DEB_PACKAGES_SOURCE not found, script defaults to source build
- Original source build scripts still work unchanged
- Existing workflows not disrupted

## Testing Notes

**Test Scenario 1:** Fresh installation from packages
```
Expected: 5-10 minute install
Actual: [To be tested]
```

**Test Scenario 2:** Switch from source to packages
```
Expected: Automatic cleanup, fresh install
Actual: [To be tested]
```

**Test Scenario 3:** Switch from packages to source
```
Expected: Cleanup, source build
Actual: [To be tested]
```
