class BlockPos {
    constructor(x = 0, y = 0, z = 0) {
        this.x = x; this.y = y; this.z = z;
    }
    parse(reader) {
        this.x = reader.readInt();
        reader.skip();
        this.y = reader.readInt();
        reader.skip();
        this.z = reader.readInt();
        return this;
    }
    listSuggestions(context, builder) {
        return Suggestions.empty();
    }
    getExamples() {
        return [
            "1 2 3"
        ]
    }
}

const dispatcher = new CommandDispatcher();

dispatcher.register(
    literal("fill").then(
        argument("pos1", new BlockPos()).then(
            argument("pos2", new BlockPos()).then(
                argument("block", string()).executes(context => {
                    console.log(context.getArgument("pos1", BlockPos))
                    console.log(context.getArgument("pos2", BlockPos))
                    console.log(context.getArgument("block", /*String*/ 3))
                    return 0;
                })
            )
        )
    )
)

const parsedCommand = dispatcher.parse("fill 3 4 5 10 11 12 air", {})
try {
    dispatcher.execute(parsedCommand);
} catch (ex) {
    console.error(ex.getMessage());
}
