This is an implementation of both the Undirected and Directed Graph from Algorithms 4e. Everything is designed to be useable and efficient.

This has been fixed, which has allowed the project to run on C++17 rather than C++20. This library, as of 1.1.0, implements the stream insertion operator, allowing for any class that also implements this to be the ID class. It also means it can be used in a wide variety of other ways. Irregardless, this does not affect the API and std::string can still very easily be used as the template type. Furthermore, this means that symbol graphs, as in Algorithms 4e, can easily be built by using a Graph<int>.

To use the graph, one must use an ID class for the Vertex struct that is Printable, as defined in include/Graph.hpp. This tests that a string can be constructed from the class, which is a necessity to ensure this graph can be output. Altering the template to accept non-printable classes is a potential improvement that may be implemented in the future.

To use this project is quite simple. One simply has to include in their CMakeLists.txt:

find_package(Graph 1.1.0 REQUIRED)
# Add Targets
target_link_libraries(Foo PRIVATE GRon::Graph)

Then, all that's necessary is to include GRon/Graph/Graph.hpp.

• C++17
• CMake 3.15+

1. Download the source code

    git clone https://github.com/Macr0Nerd/Graph.git
   

2. Move into and make am output directory

    cd Graph
    mkdir out
   

3. Generate the makefiles

    cmake -DCMAKE_BUILD_TYPE=Release ..
   

4. Build & Install the project

    cmake --install .
