A managed .NET scripting language. Get it on nuget.org.
Writing a host application requires to implement the Host interface and the method Invoke with this signature.
public object Invoke(string functionName, List<object> parameters)
Here is a full example.
using ScriptStack;
using ScriptStack.Compiler;
using ScriptStack.Runtime;
using System.Collections.Generic;
using System;
namespace StackShell
{
class StackShell : Host
{
private static Manager manager;
private static Script script;
private static Interpreter interpreter;
public static void Main(String[] args)
{
manager = new Manager();
manager.Register(new Routine((Type)null, "print", (Type)null));
script = new Script(manager, args[0]);
interpreter = new Interpreter(script);
interpreter.Handler = new StackShell();
while (!interpreter.Finished)
interpreter.Interpret(1);
}
public object Invoke(string functionName, List<object> parameters)
{
if (functionName == "print")
{
System.Console.WriteLine(parameters[0]);
}
return null;
}
}
}Writing a model (plugin) requires to implement the Model interface and the method Invoke with this signature.
public object Invoke(string functionName, List<object> parameters)
In addition it must expose a List<Routine> of all the (script) functions it implements.
public ReadOnlyCollection<Routine> Routines
Here is a full example.
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using ScriptStack;
using ScriptStack.Compiler;
using ScriptStack.Runtime;
namespace DemoModel
{
public class DemoModel : Model
{
private static ReadOnlyCollection<Routine> prototypes;
public ReadOnlyCollection<Routine> Routines
{
get { return prototypes; }
}
public DemoModel()
{
if (prototypes != null)
return;
List<Routine> routines = new List<Routine>();
routines.Add(new Routine((Type)null, "toUpper", (Type)null, "Make everything upper case"));
routines.Add(new Routine((Type)null, "toLower", (Type)null, "Make everything lower case"));
prototypes = routines.AsReadOnly();
}
public object Invoke(String functionName, List<object> parameters)
{
if (functionName == "toUpper")
{
return parameters[0].ToString().ToUpper();
}
if (functionName == "toLower")
{
return parameters[0].ToString().ToLower();
}
return null;
}
}
}
