Highlights

DiagnosticFlow - Railway-Oriented Programming

Never lose diagnostics in your pipeline:

symbol.ToFlow(nullDiag)
    .Then(ValidateMethod)
    .Where(m => m.IsAsync, asyncRequired)
    .WarnIf(m => m.IsObsolete, obsoleteWarn)
    .Then(GenerateCode);

// Pipeline integration
provider
    .SelectFlow(ExtractModel)
    .ThenFlow(ValidateModel)
    .ReportAndContinue(context)
    .AddSource(context);

Symbol Pattern Matching

Replace 50-line if-statements with composable patterns:

var asyncTask = SymbolPattern.Method()
    .Async()
    .ReturnsTask()
    .WithCancellationToken()
    .Public()
    .Build();

if (asyncTask.Matches(method)) { ... }

SemanticGuard - Declarative Validation

SemanticGuard.ForMethod(method)
    .MustBeAsync(asyncRequired)
    .MustReturnTask(taskRequired)
    .MustHaveCancellationToken(ctRequired)
    .ToFlow();  // -> DiagnosticFlow<IMethodSymbol>

Domain Contexts

Pre-cached symbol lookups for common patterns:

var ctx = new AwaitableContext(compilation);
ctx.IsTaskLike(type)
ctx.IsAwaitable(type)
ctx.CanUseAsyncKeyword(method)

var asp = new AspNetContext(compilation);
asp.IsController(type)
asp.IsAction(method)
asp.IsFromBody(parameter)

var disp = new DisposableContext(compilation);
disp.IsDisposable(type)
disp.HasDisposeMethod(type)

var coll = new CollectionContext(compilation);
coll.IsImmutable(type)
coll.GetElementType(type)

Code Generation

var sb = new IndentedStringBuilder();
using (sb.BeginNamespace("MyNamespace"))
using (sb.BeginClass("public partial", "MyClass"))
using (sb.BeginMethod("public", "void", "Execute"))
{
    sb.AppendLine("// generated code");
}

Pipeline Extensions

provider
    .SelectFlow(ExtractModel)
    .ThenFlow(ValidateModel)
    .WarnIf(m => m.IsOld, obsoleteWarn)
    .ReportAndContinue(context)
    .AddSource(context);

// Collection operations
provider.GroupBy(keySelector)
provider.Batch(100)
provider.Distinct()
provider.CollectAsEquatableArray()

Testing Library

using var result = await Test<MyGenerator>.Run(source);
result
    .Produces("Output.g.cs", expectedContent)
    .IsCached()
    .IsClean()
    .HasNoForbiddenTypes();
