Raiqub.Generators.InterpolationCodeWriter.CSharp.Sources

Provides source files for writing source generators that are embedded directly into your project. This is a development-only dependency with no runtime overhead.

This is the recommended package for most source generator projects. It embeds the source code of both InterpolationCodeWriter and InterpolationCodeWriter.CSharp directly into your project, avoiding any external assembly dependency.

Installation

dotnet add package Raiqub.Generators.InterpolationCodeWriter.CSharp.Sources

Quick Start

Implement ICodeWriter<T> to define a code writer and use CodeWriterDispatcher<T> to dispatch source generation:

public class MyWriter : ICodeWriter<MyModel>
{
    public bool CanGenerateFor(MyModel model) => model.Properties.Count > 0;

    public string GetFileName(MyModel model) => $"{model.Namespace ?? "_"}.{model.Name}Extensions.g.cs";

    public void Write(SourceTextWriter writer, MyModel model)
    {
        writer.WriteLine($"namespace {model.Namespace};");
        writer.WriteLine();
        writer.WriteLine($"public static partial class {model.Name}Extensions");
        writer.WriteLine("{");
        writer.PushIndent();
        // Write members using string interpolation...
        writer.PopIndent();
        writer.WriteLine("}");
    }
}

Then dispatch generation using CodeWriterDispatcher<T>:

private static readonly CodeWriterDispatcher<MyModel> s_dispatcher =
    new([new MyWriter()]);

private static void Emit(
    SourceProductionContext context,
    ImmutableArray<MyModel> types)
{
    s_dispatcher.GenerateSources(types, context);
}

Compatibility

Requires .NET 6.0 SDK or later, but you can target earlier frameworks.
