Includes a command-line client (

Requires numpy.

Read to get started.

See LICENSE.txt for licensing terms. is a command-line editor for SMP maps. It can be used interactively from a terminal, accept editing commands on standard input, or run a single editing command from the shell.

Sample usage:

$ python


    Block commands:
        clone <sourcePoint> <sourceSize> <destPoint>
        fill <blockType> [ <point> <size> ]
        replace <blockType> [with] <newBlockType> [ <point> <size> ]

        export <filename> <sourcePoint> <sourceSize>
        import <filename> <destPoint>


    Player commands:
        player [ <player> [ <point> ] ]
        spawn [ <point> ]

    Entity commands:
        removeEntities [ <EntityID> ]

    Chunk commands:
        createChunks <point> <size>
        deleteChunks <point> <size>
        prune <point> <size>
        relight [ <point> <size> ]

    World commands:

    Editor commands:
        load <filename> | <world number>

        blocks [ <block name> | <block ID> ]
        help [ <command> ]

    Points and sizes are space-separated triplets of numbers ordered X Y Z.
    X is position north-south, increasing southward.
    Y is position up-down, increasing upward.
    Z is position east-west, increasing westward.

    A player's name can be used as a point - it will use the
    position of the player's head. Use the keyword 'delta' after
    the name to specify a point near the player.

       codewarrior delta 0 5 0

    This refers to a point 5 blocks above codewarrior's head.
