What does it do?

Pharmacist will convert events within an assembly and create observable wrappers for them.

It has been called pharmacist since it will generate Reactive Extensions (Rx) Observables for events, so it's a play on word about "Rx" which is short for prescriptions.

It can generate the observables for the following:

  • System Platforms, such as Xamarin (iOS/Android/TVOS), UWP
  • NuGet packages
  • Assemblies.

There is a MSBuild Task version and a global tool version.

How do I use?

MsBuild

Pharmacist can automatically create Observable wrappers for projects for their explicitly included NuGet packages.

In your .csproj file you can add:

<ItemGroup>
    <PackageReference Include="Pharmacist.MsBuild" Version="1.*" PrivateAssets="all" />
    <PackageReference Include="Pharmacist.Common" Version="1.*" />
</ItemGroup>

Pharmacist.MsBuild contains the MsBuild target file and appropriate tasks. Pharmacist.Common includes common source code that is required to invoke the generated observables.

This will generate wrappers only for other included PackageReference's contained within the project file.

For example if you had a inclusion for Xamarin.Forms in the same project that includes Pharmacist it will generate Observable wrappers for the included codes. It will not include any child PackageReference from other projects included via a ProjectReference. You can override that functionality by including <PharmacistGlobalPackages>true</PharmacistGlobalPackages> in a PropertyGroup inside your project.

Also it will only generate the specified ProjectReference and none of it's dependent packages. For example for a ProjectReference inclusion of ReactiveUI, it will not generate dependencies such as System.Reactive. If you want to generate observable wrappers for the dependent NuGet packages you must explicitly include them.

Command Line

Pharmacist comes with a command line version which is useful for generating for a specified platform.

The following values are supported for platforms: Android, iOS, Mac, WPF, UWP, Winforms, TVOS

Install the global tool:

dotnet tool install -g Pharmacist

To generate files:

pharmacist generate-platform -p <Platform> -o c:/directory/for/output --output-prefix="Events"

This would generate a file named Events_<Platform>.cs, where Platform would be the platform specified.

In the near future this will be changing to TargetFramework with /wpf and /winforms options.
