In a previous post, we’ve seen that dotPeek supports creating and loading plugins. The NuGet plugin for dotPeek is a good example to demonstrate how to get started creating plugins for dotPeek. Sources for this plugin are available on GitHub. But let’s create a plugin of our own!
Before we start: dotPeek does not have a formal SDK yet. However it shares a lot of commonalities with ReSharper. In fact: dotPeek is built on the same platform as ReSharper reusing the project model, PSI, navigation and so on. Which is good news: we can use the ReSharper SDK (see the downloads page) to create plugins for dotPeek. Another option is to start from a class library project and work with a small NuGet package I’ve created to help you get started.
Creating a new plugin
To create a plugin for dotPeek, we can make use of the instructions provided with the ReSharper SDK. This involves a lot of project modifications so we’ll take the easy way out: we can create a dotPeek plugin by installing a NuGet package.
In Visual Studio, we can start out with a new Class Library project, making use of .NET 3.5 or up. Next, we can install the JetBrains.DotPeek.PluginDevelopment NuGet package into the project. This NuGet package will convert the class library we have into a dotPeek plugin by adding assembly references and several attributes. Note that the NuGet package will target the latest version of dotPeek that is installed on your system (which also means we have to have a copy of dotPeek installed).
That’s everything we have to do: by running our project, dotPeek will launch with our fresh plugin loaded:
I love products that let me extend them. Will I? Rarely, but it's the fact that I can is what draws me in...
