Hammer 0.0.1: technology preview
This is the first release of Hammer, a tool for validating HL7 FHIR® instances.
This STU3-based validator uses both the .NET and the Java validators side by side, accepts both JSON and XML, comes with a dark theme, and has an option to copy the validation report as CSV or markdown. It's completely free, open-source, and runs on Windows, macOS, and Linux.
Instructions on how to use are available here.
This application is built in C# with QML powering the interface via Qml.Net. If that sounds interesting to you, join in on the development :)
Further improvements to be added are DSTU2 and R4 support, batch validation, and meta.profile-less validation.
