This is a library mod that adds a rule-based effect system for use in Minecraft mods. Its most notable use is Waystones, where it controls the highly dynamic warp requirements, and Unbreakables, where it controls the rules of which blocks are unbreakable.
To achieve this, mods implement the Shogi API and expose properties that can then be configured using a Shogi expression, which is a simple text-based format. For information on how to write Shogi rules or how to implement Shogi for your own mod, see the documentation.
