ScriptRunner.Plugins

ScriptRunner.Plugins provides interfaces, attributes, utilities, and constants for building plugins compatible with the ScriptRunner framework. It ensures seamless plugin development with dynamic loading, validation, and integration.

---

Features

• Plugin Metadata: Annotate plugins with [PluginMetadata] for easy discovery and validation.
• Version & Framework Constants: Ensure compatibility with PluginSystemConstants.
• Dynamic Plugin Management: Discover, validate, and load plugins using IPluginLoader and DependencyLoader.
• Database Utilities: Use IDatabase for executing SQL queries and SqlGenerator for dynamic SQL generation.
• Local Storage: Store plugin data with ILocalStorage for runtime use and persistence.
• Simplified Development: Use base classes like BasePlugin and BaseServicePlugin to reduce boilerplate code.
• Plugin Template: Quickly scaffold a new plugin project using the provided template.

---

Installation

Install via NuGet:

dotnet add package ScriptRunner.Plugins

Getting Started

Scaffold a New Plugin Project

The ScriptRunner.Plugins package includes a template to help you quickly set up a plugin project. Use the dotnet new command:

dotnet new srplugin -n MyNewPlugin

This creates a project with:

• Example plugin class (Plugin.cs) using [PluginMetadata].
• Pre-configured PluginSystemConstants for versioning.
• Example service registration with IServicePlugin.

---

Quick Start

Create a Plugin

1. Define your plugin class and use [PluginMetadata] for metadata:

   using ScriptRunner.Plugins.Attributes;
   using ScriptRunner.Plugins.Utilities;
   
   [PluginMetadata(
       name: "SamplePlugin",
       description: "A simple plugin example.",
       author: "Your Name",
       version: "1.0.0",
       pluginSystemVersion: PluginSystemConstants.CurrentPluginSystemVersion,
       frameworkVersion: PluginSystemConstants.CurrentFrameworkVersion)]
   public class SamplePlugin : IPlugin
   {
       public void Initialize(IDictionary<string, object> configuration) => Console.WriteLine("Initialized.");
       public void Execute() => Console.WriteLine("Executed.");
   }

2. Register services if needed:

   public class SampleServicePlugin : IServicePlugin
   {
       public void RegisterServices(IServiceCollection services)
       {
           services.AddSingleton<IMyService, MyService>();
       }
   }

Utilities

Versioning with Constants

Use PluginSystemConstants to ensure host and plugin version compatibility:

public static class PluginSystemConstants
{
    public const string CurrentPluginSystemVersion = "1.2.0";
    public const string CurrentFrameworkVersion = ".NET 8.0";
}

Dynamic Dependency Management

Load dependencies dynamically with DependencyLoader:

DependencyLoader.SetSkipLibraries(new[] { "sqlite3.dll" });
DependencyLoader.LoadDependencies("path/to/dependencies", new ConcurrentDictionary<string, bool>(), logger);

Database Utilities

• Use IDatabase for database interaction.
• Use SqlGenerator for generating queries dynamically:

var generator = new SqlGenerator();
generator.SetType(typeof(MyEntity));
generator.SetTableName("MyTable");
var query = generator.GenerateSelectQuery();

Local Storage

Use ILocalStorage for temporary data storage and persistence:

var storage = new LocalStorage();
storage.SetData("key", "value");
storage.SaveToFile("storage.json");
storage.LoadFromFile("storage.json");

---

Simplified Development

Use base classes like BasePlugin or BaseAsyncServicePlugin to minimize repetitive code.

Example with BasePlugin:

public class MyPlugin : BasePlugin
{
    public override void Initialize(IDictionary<string, object> configuration) => Console.WriteLine("Initialized.");
    public override void Execute() => Console.WriteLine("Executed.");
}
