ESAPIX is an open source extension library for the Varian Eclipse Scripting API that contains extra methods, and bootstrapping frameworks to quickly develop applications for research and clinical use. It has no affiliation with Varian Medical Systems. It provides implementations for multithreading, asynchronous calls, debugging plugins, and with the ESAPIX.Bootstrapping library : dependency injection, and view model "auto finding" through the Prism 6 library.

1. Install the appropriate ESAPIX library (Version) through NuGet.
   • Right click your project >> Manage NuGet Packages >> (Search "ESAPI")
2. In your project, instead of calling:

 var app = Application.CreateApplication("...");

Call :

var sac = new StandAloneContext(()=>Application.CreateApplication("..."));

Using ESAPIX StandAloneContext (SAC) wraps the real Varian classes in a thread controlled environment using Facades. This trick allows for using easy multithreading since ESAPIX will handle calling VMS proper classes on the correct thread. Additionally, these lightweight wrappers (Facades) can be used to mock Varian classes for unit testing and offline development. Also, the data can be quickly serialized into JSON using the FacadeSerializer class.

Most of all, ESAPIX is a unified, open source framework that is designed to be used and contributed to by the medical physics community. It uses the MIT open source license to ensure that code can be used in whatever tools you need in the fight against cancer. If you are interested in contributing code, please see an example of submitting code to this repository.
