Burn to the Brim (C++ Port)

Burn to the Brim (BTTB) is a modern C++20 desktop application designed to optimally fit files and folders onto target storage mediums (such as CDs, DVDs, or Custom sizes).

This is a complete port of the classic Delphi application to C++20 supporting:

1. Linux: Natively compiled GTK 4 desktop application running on Ubuntu 24.04+.
2. Windows: Native, lightweight Win32 SDK GUI desktop application running natively on Windows with zero external DLL dependencies.

It solves the subset-sum / bin packing problem instantly using an advanced recursive backtracking solver, matching files efficiently, and providing file organization and ISO creation capabilities.

Features

• Backtracking Bin Packing Solver: Employs the highly optimized subset-sum algorithm from the original BTTB version, executing in milliseconds with a fluid non-blocking background thread.
• Directory Split Constraints: Control directory structures by configuring a splitDepth waterlevel (atomic vs recursive scanning).
• Modern Rule Groupings: Group files/directories together on the same medium using standard wildcards (globs) or powerful regular expressions (std::regex).
• File Organization: Copy or move matched selections directly to target organizing folders automatically.
• ISO Creation Integration: Generate ISO 9660 / Joliet / Rock Ridge images natively via standard command line utilities (genisoimage/mkisofs) with real-time log capturing.
• Vibrant User Interfaces:
• Linux (GTK 4): Standard GNOME Adwaita aesthetic featuring a HeaderBar, scrolling side results tree, interactive progress tracking, and detailed colored log viewer.
• Windows (Win32 Native): Ultra-lightweight (~160KB standalone binary), statically linked, utilizing standard native Windows SDK controls, comctl32 progress elements, and Windows Shell folder selectors.

Windows Installation & Running

1. Download and Run

Simply extract the release package bttb-cpp-3.2.0-Win64-Native-GUI.zip and run:

• bttb_win32.exe: Double-click to launch the native Windows GUI application instantly!

2. Creating ISO Images on Windows (Optional)

To use the Create ISO Image feature, a command-line ISO generation utility (genisoimage.exe or mkisofs.exe) must be installed on your Windows system and added to your environment PATH.

Here are the simplest ways to install it:

• Method 1: Using Scoop (Recommended - Easiest & Automatic PATH)
• Open PowerShell and run this command to install Scoop (if not installed):
  powershell irm get.scoop.sh | iex
• Install cdrtools (which includes mkisofs):
  powershell scoop install cdrtools

• Restart Burn to the Brim and create your ISO!

• Method 2: Using Chocolatey (Automatic PATH)

• Open an Administrator PowerShell and run:
  powershell choco install cdrtools

• Restart Burn to the Brim and create your ISO!

• Method 3: Using Cygwin

• Run the Cygwin setup-x86_64.exe installer.
• In the Package Selection screen, search for and select the cdrkit (contains genisoimage) or cdrtools (contains mkisofs) package.
• Add C:\cygwin64\bin to your Windows System environment variable PATH.

• Restart Burn to the Brim.

• Method 4: Using MSYS2

• Open your MSYS2 UCRT64 terminal and install cdrtools:
  bash pacman -S mingw-w64-ucrt-x86_64-cdrtools
• Add C:\msys64\ucrt64\bin to your Windows System environment variable PATH.
• Restart Burn to the Brim.

Linux Installation & Running (Ubuntu 24.04)

1. Install Dependencies

sudo apt update
sudo apt install -y libgtk-4-dev build-essential cmake pkg-config genisoimage

2. Building from Source (Linux)

Compile the application from the root of the project folder:

# Create and navigate to the build folder
mkdir -p build
cd build

# Configure and compile
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j$(nproc)

This compiles:

1. bttb: The GTK 4 desktop GUI application.
2. test_solver: An offline programmatic unit test suite.

3. Running on Linux

# Launch the desktop app
./build/bttb

# Run the unit tests
./build/test_solver

Building from Source (Windows MSYS2 UCRT64)

To build the native GTK 4 Windows GUI from source:

1. Open the MSYS2 UCRT64 terminal.
2. Update system and install the compiler, CMake, and GTK 4:
   bash pacman -Syu pacman -S mingw-w64-ucrt-x86_64-toolchain mingw-w64-ucrt-x86_64-cmake mingw-w64-ucrt-x86_64-gtk4
3. Navigate to the project root directory and build:
   bash mkdir build && cd build cmake -G "MinGW Makefiles" -DCMAKE_BUILD_TYPE=Release .. mingw32-make -j$(nproc)

Generating Release Packages and Installers (Cross-Compilation on Ubuntu)

To cross-compile the Windows binaries, build the .msi installers, and generate the Linux .deb packages on an Ubuntu development machine:

1. Install Prerequisites

Install the required build tools, cross-compilers, and packaging utilities:

sudo apt update
sudo apt install -y \
  build-essential \
  cmake \
  pkg-config \
  libgtk-4-dev \
  genisoimage \
  gcc-mingw-w64-x86-64 \
  g++-mingw-w64-x86-64 \
  msitools

2. Run the Release Packaging Script

Navigate to the project root directory and run the packaging script:

python scratch/package_release.py

This script automates the entire packaging pipeline:

1. Linux Compilation: Compiles the native GTK 4 application and generates the .deb package via CMake.
2. Windows Cross-Compilation: Uses MinGW-w64 to build the native 64-bit Windows GUI executables (bttb_win32.exe and bttb_win32_compat.exe) with exploit mitigations and strips symbols.
3. Release ZIPs: Packages all portable ZIP archives for Linux and Windows releases.
4. MSI Installer Creation: Converts the plain-text LICENSE file into a formatted License.rtf and runs wixl to compile the enterprise-grade .msi installers in the build/ directory:
5. bttb-cpp-4.4.0-Win64-Installer.msi (Native AVX2 release)
6. bttb-cpp-4.4.0-Win64-Compat-Installer.msi (Compatibility SSSE3 release)
7. Unified Source Archive: Generates the unified source code ZIP.
