/dsreload

Causes Dynamic Surroundings to clear internal caches and rescan registries, mod assets, resource packs, and disk configuration locations. Useful when developing resource packs where changes are made and need to be hot loaded without exiting the Minecraft client. Can also be used if a desync is suspected.

/dsscript <script>

Executes an arbitrary JavaScript entry and displays the result. For example, /dsscript Math.sqrt(9) * 6 should respond with 18. Useful for performing calculations on the side as well as testing.

/dsbiome <biome ID> <script>

Executes an arbitrary JavaScript entry using the specified biome configured in the JavaScript execution environment. Useful for testing biome selector script fragments. For example, /dsbiome minecraft:plains OVERWORLD && PLAINS should return true.

/dsdump <subcommand>

Dumps out cached information to the minecraftinstance/config/dsurround/dumps folder. Useful when creating a resource pack and the final cached result needs to be analyzed.
