RuleScript

Build Stable Version NuGet Version NuGet Downloads

RuleScript is a lightweight, embeddable .NET 8 scripting engine for rule-oriented workflows, automation, validation, JSON processing, and host-controlled execution.

It provides a lexer, parser, AST, interpreter, built-in functions, user functions, project imports, Host Function integration, runtime diagnostics, and debugger APIs without exposing a full general-purpose programming language.

Installation

Install the stable package from NuGet:

dotnet add package RuleScript.Core --version 1.9.0

Quick Start

using RuleScript.Core.Runtime;

var engine = new RuleScriptEngine();
var context = new RuntimeContext();

context.Set("Name", "Mick");
context.Set("Distance", 519);

engine.Execute("""
    var message = "Hello " + Name;

    if Distance > 500 then:
        result = message + ": NG";
    else:
        result = message + ": OK";
    endif
    """, context);

Console.WriteLine(context.Get<string>("result"));

Run a project file:

var engine = new RuleScriptEngine
{
    WorkingDirectory = @"C:\rules"
};

var context = engine.ExecuteFile("main"); // Resolves main.rules

Register a Host Function:

engine.RegisterFunction("GetDistance", _ => 519);

var context = engine.Execute("result = GetDistance();");

Documentation

Detailed syntax, Host integration, debugging, analysis, and version-specific behavior are maintained in the RuleScript Wiki.

Development

The latest stable source is available on main. See the v1.9.0 release notes for strongly typed functions and overload resolution. See the v1.8.0 maintenance notes for unified function symbols, shared source ranges, and reusable document analysis.

dotnet build RuleScript.sln
