This repository contains a C++ app to help guide drones for a local tech savvy chicken farmer to deliver eggs on time.

The project is structured in such away that it can be simply build and tries to be modular in terms of the project layout. The project is structured as following

.
├── app                   # Main application which provides drone positions
│  ├── CMakeLists.txt
│  └── main.cpp
├── CMakeLists.txt
├── data                  # Sample data input/output
│  ├── input.example
│  └── output.example
├── include               # Include files for main implementation
│  ├── drone.h
│  ├── input.h
│  └── world.h
├── README.md             # Readme for the example
├── src                   # Main program logic/implementation
│  ├── CMakeLists.txt
│  ├── drone.cpp
│  ├── input.cpp
│  └── world.cpp
└── tests                 # Tests for main implementations
   ├── CMakeLists.txt
   ├── test_drone.cpp
   ├── test_input.cpp
   └── test_world.cpp

The project can be simply build using an out-of-source build by running the following commands in the terminal

mkdir build
cmake -S . -B build
cmake --build build

Pay attention that the project uses a newer CMake version. The minimum requirement for CMake cmake_minimum_required(VERSION 3.11) is 3.11. The reasoning for ths is the use of FetchContent which downloads Catch 2 and uses this for testing.

The app can be run by piping the example stored in data/input.example:

cat data/input.example | build/app/dronenav

which should return

1 3 N
5 1 E

and that corresponds to the output stored in data/output.example.

The tests are build using Catch2. They can be after the project has been build by running the following executables

build/tests/test_drone
build/tests/test_input
build/tests/test_world

Following points might need attention in the future

• Validate performance
• Provide better error output, e.g. own try-block around std::atoi
