Building gears

gears currently require:

• On the JVM: JVM with support for virtual threads. This usually means JVM 21+, or 19+ with --enable-preview.
• On Scala Native: Scala Native with delimited continuations support, which are available from 0.5.0. Right now we are using 0.5.1.

All of the needed dependencies can be loaded by the included Nix Flake. If you have nix with flake enabled, run

nix develop

to enter the development environment with all the dependencies loaded. You can also use direnv's use flake to automate this process.

Once done, it should suffice to run

sbt publishLocal

to have Gears compiled and published locally for usage.

Running Tests

sbt test
