If you’d like to help advance our work, we are ever grateful for all forms of contribution, either by volunteering time or financial backing.

Local build instructions

Section titled “Local build instructions”

Tyrian is fairly straight forward to build locally, run the following commands from your terminal in the project root:

Terminal window
npm install
sbt clean update compile test +publishLocal

There is also a build.sh script in the root folder, but that also builds the docs and example projects (based on the currently released version).

Nix dev-shell

Section titled “Nix dev-shell”

If you would like to have the environment set up without installing any dependencies globally (think node, yarn, java, etc), you can give the Nix development shells a try.

To use this functionality, you are required to enable flakes.

Usage

Section titled “Usage”
Terminal window
$ nix develop

Locally you can run nix develop. However, if you would like to use the same shell in a different repository, you can run the following command instead.

Terminal window
nix develop github:PurpleKingdomGames/tyrian

What do you get?

Section titled “What do you get?”

The default dev shell ships with jdk, mill, sbt and coursier, ensuring all dependencies use the same JDK. It also ships with essential JS tooling in the form of yarn, npm and node.
