L5Sharp.Generators.Data 7.2.0

L5Sharp.Generators.Data

A Roslyn incremental source generator that automatically creates strongly-typed L5Sharp LogixData classes from L5X files.

Overview

L5Sharp.Generators.Data simplifies the process of working with custom User-Defined Types (UDTs) and Add-On Instructions (AOIs) in your C# projects. Instead of manually defining classes to match your Logix data structures, you can include your L5X project file as an AdditionalFiles item in your project. The generator will then produce the corresponding C# classes, complete with automatic registration into the L5Sharp type system.

Features

• Automatic Type Generation: Generates C# classes for all UDTs and AOIs found in the provided L5X files.
• Incremental Generation: Optimized for performance using the Roslyn Incremental Generator API.
• Automatic Registration: Generates a ModuleInitializer to register all produced types with LogixType.Register, ensuring they are available to L5Sharp at runtime.
• Type Safety: Maps Logix members to their corresponding LogixData or atomic types in C#.
• Seamless Integration: Works directly with the L5Sharp.Core library.

Installation

Add the L5Sharp.Generators.Data package to your project. Since this is a source generator, it should be added as an analyzer/development dependency.

<ItemGroup>
  <PackageReference Include="L5Sharp.Generators.Data" Version="x.x.x" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />
  <PackageReference Include="L5Sharp.Core" Version="x.x.x" />
</ItemGroup>

Usage

1. Add L5X Files: Add the L5X file containing your type definitions to your project as AdditionalFiles.

<ItemGroup>
  <AdditionalFiles Include="MyLogixProject.L5X" />
</ItemGroup>

2. Access Generated Types: Once added, the generator will produce classes for each UDT/AOI. You can then use these types just like any other L5Sharp type.

// If you have a UDT named 'MyCustomType' in your L5X.
var myTag = Tag.New<MyCustomType>("SomeTag");
myTag.Value.As<MyCustomType>().SomeMember = 123;

3. Automatic Registration: You don't need to manually call LogixType.Register. The generator creates a LogixDataRegistration class with a [ModuleInitializer] that handles this for you when the assembly is loaded.

How it Works

The generator scans all AdditionalFiles with an .L5X extension. It parses the DataTypes and AddOnInstructionDefinitions sections to build a model of the types. For each type, it generates a partial class inheriting from StructureData or StringData (depending on the type family), as well as properties for all type members in the definition.
