A Ruby shell in Autodesk Revit using IronRuby.

RevitRubyShell is a Ruby shell in an Autodesk Revit add-in external application.

It enables you to interactively run Ruby scripts inside Revit using the Revit API and IronRuby.

You can build from source and add the add-in manually or using the add-in manager.

There is also an automated installer available here (IE only) or here.

This application is heavily inspired by RevitPythonShell and this article about embedding IronRuby.
