CClaims: A container claim mod for fabric

Claims is a Fabric server-side mod to claim and protect container blocks (e.g. Chest, Barrels and Hoppers).

This mod provides the /cclaim command to work with the claims. Permissions can be managed by LuckPerms or any other mod implementing the fabric-permissions-api.

Features:

Supported Container Blocks: Chests, Copper Chests, Barrels, Hoppers, Shelfs, Brewing Stands and Beacons
Prevents usage and destruction of claimed blocks by other players (except admin mode players)
- Prevents destruction by explosions, headless pistons (aka. the bedrock breaking method) or the Ender dragon
Players can add ("trust") players to their claims.
Claims can trust registered groups that can be managed dynamically by players

Note: Claimed hoppers will push items into unclaimed containers. Therefore, you should not have claimed hoppers facing an unclaimed block (including normal non-container blocks that cannot be claimed).

Commands

/cclaim claim: Claims the container the player is facing
/cclaim unclaim: Unclaims the container the player is facing
/cclaim trust <player>: Trusts a player to use the claimed container. Trusted players can only use the container, but neither destroy the block nor manage the claim.
/cclaim untrust <player>: Untrusts a player from a claimed container
/cclaim trust group <group>: Trusts a group to use the claimed container.
/cclaim untrust group <group>: Untrusts a group to use the claimed container.
/cclaim info: Shows the current claim status of the container the player is facing
/cclaim adminmode: Toggles if the player is in admin mode. The mod treats players in admin mode like they own every claim.
/cclaim list [<dimension>] [all]: Lists the coordinates of all container claims in a dimension (defaults to the overworld). By default, the list is paginated, but this can be turned off by adding "all" as an argument.
/cclaim group create <group>: Creates a new group. The group name is limited to lowercase letter, numbers and underscores and has to be between 3 and 16 characters long.
/cclaim group delete <group>: Deleted a group.
/cclaim group join <group> <player>: Adds a player to the group.
/cclaim group leave <group> <player>: Removes a member from the group.
/cclaim group info <group>: Shows the name, owner and members of the group.
/cclaim group list: Lists all groups the player is a member of.
/cclaim group transfer <group> <player>: Changes the owner of a group.
