Well I appreciate the feed back, and have posted the source to my
website at [http://home.comcast.net/~logospathosethos/]. As for some more
details on how it works, let me highlight three areas. The code should be
fairly self explanatory, the first queries every method in the ‘communicator’
class, the second matches a GTP command with a method name, and the third
defines the communicator class. Notes: ·
If you can't tell, my Go program
is called Gozilla- which unfortunately has already been taken so I will
probably rename it if I let it out into the wild. ·
The code uses the .NET Framework
2.0, to compile it I would recommending downloading a copy of C# Express from [http://lab.msdn.microsoft.com/express/vcsharp/] public GozillaThroughGTP(bool excludeI) { m_bRunning
= true; /** * Use reflection to
create an instance of GozillaCommunicator and * query all of its
members so that we can define which GTP commands are * known at runtime
without much of a mess. This also makes enhancing the * Gozilla GTP command
system MUCH easier. */ Type
gozillaCommunicator = typeof(GozillaCommunicator); // Create an instance of it 'somewhere'
in memory object[] arguments = {
excludeI }; m_gozillaCommunicator
= (GozillaCommunicator)
Activator.CreateInstance(gozillaCommunicator,
arguments); // Add the commands to a list, neglecting
ToString, GetHashCode and others. m_GTPCommands
= new List<MethodInfo>(); MethodInfo[]
allMethods = gozillaCommunicator.GetMethods(); StringCollection
invalidMethods = new StringCollection(); invalidMethods.Add("Equals"); invalidMethods.Add("GetHashCode"); invalidMethods.Add("GetType"); invalidMethods.Add("ToString"); foreach (MethodInfo method in allMethods) { // If it isn't on our banned list it is
OK by me if
(invalidMethods.IndexOf(method.Name) == -1) m_GTPCommands.Add(method); } } private String ExecuteCommand(String
command, String
arguments) { m_bCommandHadError
= false; // See if the command exists in our
GozillaCommunicator foreach (MethodInfo method in m_GTPCommands) { if (method.Name == command) { GTPCommandInput
ip = new GTPCommandInput(arguments); object[] methodargument = {
ip }; // Invoke the method GTPCommandOutput
op = (GTPCommandOutput)method.Invoke(m_gozillaCommunicator,
methodargument); // Yeah! if (op.HasError)
m_bCommandHadError = true; return op.Output; } } // known_command checks if the argument
is a supported command or not if (command ==
"known_command") { foreach (MethodInfo method in m_GTPCommands) { if (method.Name == arguments) return "true"; } return "false"; } // list_commands lists all supported GTP
commands if (command ==
"list_commands") { StringBuilder
knownCommands = new StringBuilder(); foreach (MethodInfo method in m_GTPCommands) { knownCommands.Append(method.Name
+ "\n"); } // Add the ones that are in this module knownCommands.Append("known_command\n"); knownCommands.Append("list_commands\n"); knownCommands.Append("quit"); return knownCommands.ToString(); } // Terminate if (command ==
"quit") { m_bRunning
= false; return ""; } // All else fails, error m_bCommandHadError
= true; return "unknown
command"; } public class GozillaCommunicator { public GozillaCommunicator(bool bIgnoreIs) { m_engine
= new GozillaGoEngine(); m_bIgnoreIs
= bIgnoreIs; } /// <summary> /// The actual Go engine /// </summary> private GozillaGoEngine m_engine; /// <summary> /// Whether or not the Go program should
ignore 'I' when issued board points, so /// I9 will return an error and J is the
9th coloumn on the board /// </summary> private bool m_bIgnoreIs; #region
"Meta-Commands" /// <summary> /// Returns the name of the Go program /// </summary> /// <param name="input"></param> /// <returns></returns> public GTPCommandOutput name(GTPCommandInput
input) { return new GTPCommandOutput("Gozilla",
false); } /// <summary> /// Displays the version information of
Gozilla /// </summary> /// <param name="input"></param> /// <returns></returns> public GTPCommandOutput version(GTPCommandInput
input) { return new GTPCommandOutput(m_engine.EngineVersion,
false); } (The class goes on…) |
