To all my friends who use Windows for their daily tasks (usually at work) and enjoy tinkering with Ruby, now there’s a way to write, edit, and debug your Ruby code within Visual Studio .NET 2005. Note that I’m not refering to Ruby.NET, an implementation being developed by Dr. Wayne Kelly and Prof. John Gough of the Queensland University of Technology. This tip was sent my way by my friend Gerrard Lindsay, a Microsoft consultant for the East Region of the United States.The first step would be to install the version of Ruby for Windows. Download the installer and simply double-click it. WARNING:: I noticed that the installer modified my PATH environmental variable, pretty much wiping it clean and adding the location for the Ruby compiler. Therefore, make a back-up of its content before proceeding with the installation.Once the installation is completed, you can pretty much hit the ground running and start coding using any old text editor. If you do not have a copy of Visual Studio .NET 2005 installed, and don’t quite enjoy coding using Notepad (who would?), try Notepad2, which is not only free but has Ruby syntax support built-in! Now, to add suport for editing and debugging Ruby code in Visual Studio .NET 2005, download the add-in Sapphire In Steel and follow the installation instructions. Take the time to also download the free book (PDF) and source code to follow along. The best part is that you can work in your Ruby code, without any modifications, no matter which plataform you’re working on. Add a dash of SVN and you’ll be set! UPDATE:  I mistakenly stated that the Ruby.NET implementation has been done by the Mono guys, but it was actually done by Dr. Wayne Kelly and Prof. John Gough of the Queensland University of Technology   I apologize for the confusion.
