FTowerX

An implementation of the Tower of Hanoi game, following best practices.

This is a cross-platform, lightweight, terminal-based implementation of the Tower of Hanoi, featuring automated testing, coverage reports, packaging, and more. It also includes generated library files that you can link to create custom user interfaces or extend the current implementation with ease.

Executable and Library

This project uses the SeeMake template. To build it on either Windows or Linux, you need to install the required packages and software first. For Linux instructions, see here, and for Windows setup, follow these instructions.

After installing the dependencies, use the following commands to build all the artifacts, run tests, and create installers:

# On Linux
cmake --workflow --preset linux-default-release

# On Windows
cmake --workflow --preset windows-clang-release
# or
cmake --workflow --preset windows-default-release

You should see the following message after the build:

100% tests passed, 0 tests failed out of 21

Installation and Packaging

On Linux, you should also see the following message indicating that the installation package was successfully created:

CPack: - package: /repos/FTowerX-build-linux-default-release/package-linux-deb/FTowerX-0.0.0-Linux.deb generated.

On Windows, the following success message will appear:

CPack: - package: C:/Users/Mohammad Rahimi/Documents/FTowerX-build-windows-clang-release/package-windows-nsis/FTowerX-0.0.0-win64.exe generated.

You can use the generated installers to install the game, or use CMake to install it:

cmake --install <build-directory> --prefix <installation-directory>

This is how your installation-directory will look:

tree ../installation-directory/

# ../installation-directory/
# ├── bin
# │   └── toh
# ├── include
# │   └── toh
# │       └── toh_model.h
# └── lib
#     ├── libtoh.a
#     ├── libtoh.so
#     └── toh
#         └── cmake
#             ├── TohConfig.cmake
#             ├── TohLibrary.cmake
#             └── TohLibrary-release.cmake
#
# 7 directories, 7 files

Tests and Coverage Reports

During the build process, tests will run automatically. To generate coverage reports, run these commands:

# On Linux
# For the library
cmake --build --preset linux-default-debug --target coverage-google_test_libtoh
# For the executable
cmake --build --preset linux-default-debug --target coverage-google_test_toh

# On Windows
# For the library
cmake --build --preset windows-clang-debug --target coverage-google_test_libtoh
# For the executable
cmake --build --preset windows-clang-debug --target coverage-google_test_toh

You should see the coverage output in the terminal:

Overall coverage rate:
lines......: 91.4% (32 of 35 lines)
functions......: 75.0% (6 of 8 functions)

Coverage reports are also available in HTML format. Navigate to the report subdirectory in the build directory and run the following command:

python -m http.server <port-number>

Python will serve the report in your browser, or you can simply open the index.html file in your browser.

Documentation

Doxygen documentation can also be generated similarly to the coverage reports:

# On Linux
# For the library
cmake --build --preset linux-default-release --target doxygen-libtoh_static
# For the executable
cmake --build --preset linux-default-release --target doxygen-terminal_toh_static

# On Windows
# For the library
cmake --build --preset windows-clang-release --target doxygen-libtoh_static
# For the executable
cmake --build --preset windows-clang-release --target doxygen-terminal_toh_static

Extending

You can link your projects to this one by following these steps:

1. Use CMake's FetchContent to retrieve this project. Your CMakeLists.txt file might look like this:

cmake_minimum_required(VERSION 3.30.0)
project(Extension VERSION 0.0.0 LANGUAGES CXX)

include(FetchContent)
FetchContent_Declare(LibToh
    GIT_TAG main
    GIT_REPOSITORY https://github.com/MhmRhm/FTowerX.git
)
FetchContent_MakeAvailable(LibToh)

add_executable(extension main.cpp)
target_link_libraries(extension PRIVATE toh::precompiled toh::libtoh_shared)

2. Create a .cpp file containing the main function:

#include <iostream>
#include <format>
#include "libtoh/toh_model.h"

int main() {
  using Play = std::vector<toh::Position>;

  toh::Game game{10};
  Play plays{};
  solveToh(plays, 10, toh::Left, toh::Middle, toh::Right);

  std::cout << std::format("game.isFinished() = {}", game.isFinished())
            << std::endl;

  for (auto &&play : plays) {
    game.select(play);
  }

  std::cout << std::format("game.isFinished() = {}", game.isFinished())
            << std::endl;
}

3. To simplify things, copy the CMakePresets.json file from this project into yours. Then run the build command:

cmake --workflow --preset linux-default-debug

Now, you should be able to run your program:

game.isFinished() = false
game.isFinished() = true
