package com.sillysoft.lux;////  Gemisys.java//  Lux////  This class is an implementation of the MapGenerator interface //  that uses an external script to do the work.// //  Feel free to use this file as a basis for your own external map//  generator.  So long as the OS you are running on supports the Process//  class, it should work for any external program that generates .luxb//  maps.//  To convert to your own generator, these are the steps.//  1) Copy this file and name it something distinctive (ex: ElectroLux.java).//  1) Change the class name to the same as the file name (ex://        public class ElectroLux implements LuxMapGenerator//  1) Modify the scriptName to point at your external script, program, //     exe, etc.  Whatever it is that generates the maps (ex://        private static final String scriptName = "householdappliance.pl";//  1) Modify the String name() method to return your generator's name (ex://        public String name() { return "ElectroLux"; }//  1) To use getChoices directly, without having to modify it, set your//     script to return a series of available choices, one per line, when //     called with a single command line argument of "choices".  For example,//     Gemisys returns (without the comment markers, obviously):// 500x400// 600x500// 700x600// 800x700// 900x750//     Feel free to use a different method in your own code, just make sure//     that the changed protocol is mirrored in both sides of the call, in//     this file and in the script, exe, etc.//   1) Change the description()//   1) Make sure your script can be called with exactly two arguments, //      the first being identical to one of your previously returned supported//      choices, the other being a random number generator seed (which, you //      can of course ignore, if your generator only generates a single map).//  modification history//  --------------------//  01b,07jul04,rip Gemisys port of MabilGen to 4.0 beta of lux mapgen interf.//  01a,01apr04,rip MabilGen written to 3.98 beta of lux mapgen interfaceimport java.io.*;import java.util.*;public class Gemisys implements LuxMapGenerator{private static final String scriptName = "gemisys.pl";public String name() { return "Gemisys"; }public List getChoices()  {  System.out.println(name()+" getChoices() called...");  List vChoices = new Vector();  String[] command =    {    MapLoader.getMapGeneratorPath() + scriptName,    "choices"    };  System.out.println(name()+" path: "+command[0]);  try    {    Process pr = Runtime.getRuntime().exec( command );    BufferedReader in =      new BufferedReader( new InputStreamReader( pr.getInputStream() ));     String result;    while ((result = in.readLine()) != null )      {      if( result != "")        {        vChoices.add( result );        System.out.println(name()+" choice "+result+" added.");        }      }    }  catch (Exception e)    {    System.out.println(name()+" caught an exception: "+e);    }  return(vChoices);  }  public float version()  {  return 1.0f;  }public String description()  {  return name()+" map generator brought to you by gemisys at ferkel co uk!";  }  public boolean generate(PrintWriter out, String choice, int seed,     MapLoader loader)  {  try    {    loader.setLoadText("Invoking external script");            // Invoke an OS command to run the external script.    // The first element is the path of the script to run.    // All other elements are the arguments sent to the script.
