Copenhagen Hnefatafl

  Install

An engine similar to the Go Text Protocol, a client, and a server. For help on how to use the engine see the module documentation.

Building and Running

First you need to install Rust. Then:

git clone https://github.com/dcampbell24/hnefatafl.git
cd hnefatafl

You can pass -- --help to any of the following commands to get all of the runtime options.

Then you can run the engine with:

cargo run --release --bin hnefatafl-text-protocol -- --display-game

or you can start a local server:

cargo run --release

and run a client:

# On Windows pass to cargo `--features console` to see console output.
# Pass to cargo `--features debug` to enable iced debugging.
cargo run --release --example hnefatafl-client -- --host localhost

If you are running on Linux, you'll need some dependencies as described on the website.
