1YPOS: YieldProlog for OpenSim
2
3 a compiler from Prolog to OpenSim compatible C# scripts
4
5Ported by Kino Coursey and Douglas Miles at Daxtron Labs.
6Based on Jeff Thompson Yield Prolog, http://yieldprolog.sourceforge.net/
7For Prolog see http://en.wikipedia.org/wiki/Prolog
8
9
10INTRODUCTION
11
12This folder contains code to implement a Prolog compiler using the "Yield Statement" found in C#, Javascript, and Python.
13The original Yield Prolog system can transform Prolog programs into C# code.
14In this system we detect and extract YieldProlog code (with "//YP" as the first four characters in the script) and seperate it from any c# code ("marked by "//CS").
15The YP code is transformed to C# and prepended to the "//CS" section, and passed as a bundel to the existing C# compiler.
16The end result is Prolog can interface to OpenSim using the existing "//CS" functionality, and C# can call the compiled Prolog.
17As such YP allows both declaritive and procedural programming in a 3D script enabled environment.
18
19FEATURES
20* Allows implementation of logic programming for objects and agents.
21* C#/Javascript/Python as intermediate language
22* Yield Prolog has relatively high speed of execution which is important in OpenSim. http://yieldprolog.sourceforge.net/benchmarks.html
23* It is compatable with the existing C#/Mono based system.
24* Yield Prolog is BSD license
25* Calling Prolog from C# scripts
26* Calling C# functions (with LSL and OS functions) from Prolog
27* Prolog dynamic database
28* Edinburgh, Cocksin & Mellish style syntax.
29* Compiler is generated by compiling the Prolog descrition of itself into C#
30* Same script entry interface as LSL
31
32
33TODO
34* Utilize ability to generate Javascript and Python code
35* Integrate Prolog database with Sim
36* Translation error reporting back to the editor
37* Communications via message passing
38* Interface to external inference engines
39
40POSSIBILITIES
41* Inworld expert systems
42* Parallel logic programming and expert systems
43* Ontology based processing
44* Knowledge based alerting, accessing and business rules
45 For instance, listen on channel x, filter the events and broadcast alerts on channel y
46 or send IM, emails etc.

49USAGE:
50
51Add "yp" as an allowed compiler
52
53OpenSim.ini
54[ScriptEngine.DotNetEngine]
55AllowedCompilers=lsl,cs,js,vb,yp
56
57Enter scripts using the inworld editing process. Scripts have the following format.
58The first line of a file must have "//yp".
59
60//yp

70C# code calling a Prolog Predicate:
71-----------------------------------
72The Prolog predicate is transformed into a C# boolean function. So the general calling format is:
73 foreach( bool var in prolog_predicate(ARGS)) {};
74
75I/O is via using a string reader and writer in conjunction with YP.See() and YP.Tell()
76
77 StringWriter PrologOutuput= new StringWriter();
78 StringReader PrologInput= new StringReader(myInputString);
79 YP.see(PrologInput);
80 YP.tell(PrologOutuput);
81 <CALL PROLOG CODE HERE>
82 YP.seen();
83 YP.told();
84 StringBuilder builder = PrologOutput.GetStringBuilder();
85 string finaloutput = builder.ToString();
86
87Any prolog reads and writes will be to the passed StringReader and StringWriter. In fact any TextReader/TextWriter class can be used.
88
89Strings in Prolog are stored as Atom's and you need to use an Atom object to match.
90
91\\yp
92wanted('bob').
93\\cs
94string Who="bob";
95foreach( bool ans in wanted(Atom.a(Who) )){};
96
97
98Prolog code calling a C# function:
99-----------------------------------
100The prolog code uses the script_event('name_of_function',ARGS) builtin, which is transformed into the function call.
101The C# function called uses "PrologCallback" and returns a boolean.
102
103
104
105Dynamic database assertions:
106-----------------------------------
107
108void assertdb2(string predicate, string arg1, string arg2)
109{
110 name = Atom.a(predicate);
111 YP.assertFact(name, new object[] { arg1, arg2 });
112}
113
114void retractdb2(string predicate, string arg1, string arg2)
115{
116 name = Atom.a(predicate);
117 YP.retractFact(name, new object[] { arg1, arg2 });
118}
