This project is a .NET source generator which produces IObservable<T> for events contained within a object including all base classes. ObservableEvents generator will convert events within an assembly and create observable wrappers for them, it is based on Pharmacist and uses .NET Source Generator technology.
Make sure your project is using the newer PackageReference inside your CSPROJ. The older style is buggy and should be moved away from regardless. See here for discussions how to upgrade.
Install the following packages to start using Observable Events.
| Name | Platform | NuGet |
|---|---|---|
| ReactiveMarbles.ObservableEvents.SourceGenerator | Core - Libary |  |
Include the following in your .csproj file
<PackageReferenceInclude="ReactiveMarbles.ObservableEvents.SourceGenerator"Version="1.0.2"PrivateAssets="all" />The PrivateAssets will prevent the ObservableEvents source generator from being inherited by other projects.
It injects a class for instance based events into your source code which will expose a extension method called Events(). You need to include the namespace ReactiveMarbles.ObservableEvents to access to the extension method. You can then use this to get IObservable<T> instances from your events.
usingReactiveMarbles.ObservableEvents;publicvoidMyClass: INotifyPropertyChanged
{// Assumes this belong in a class with a event called PropertyChanged.publicvoidRunEvents(){this.Events().PropertyChanged.Subscribe(x =>Console.WriteLine($"The {x} property has changed"));}publiceventPropertyChangedEventHandler PropertyChanged;}You must use include a attribute GenerateStaticEventObservables on the assembly level for a particular class. This will generate a class RxEvents in the same namespace as the specified class.
[assembly:GenerateStaticEventObservablesAttribute(typeof(StaticTest))]publicstaticclassStaticTest{publicstaticeventEventHandler?TestChanged;}
