Command:

Currently the simplest way to run the game is via Gradle:

gradlew --console=plain run

Note the use of --console=plain. This is required to prevent Gradle from overwriting the game's output. Without this option the game would be unplayable.

This is a development release, the game is now fully implemented.

Command:

My original intention was to document the TREK.BAS code. At some point I started writing it in Groovy and ended up with the code you see today.

This is not a direct port of the original game. My intention was to replicate the game play, not the spaghetti code flow. While documenting the BASIC-PLUS source I uncovered several bugs. These bugs are not present in Trk21, thus it's not possible to exactly reproduce a TREK game in Trk21. If you plug the same random number source into both apps the game will still will rapidly differ, due to a bug in the TREK.BAS ship maneuvering logic.
