GNAVI/GWindows/GNATCOM is a full set of RAD tools for Ada on Windows, seems it was just activated after long inactive state (from 2004 to 2007), it is also based on GNAT.
I was playing with it for couple of hours while I was looking for a good IDE for my Ada learning, but finally I decided to do RAD later, actually, I decided to try to avoid IDE if I can.
Let’s see how far I can go, without IDE. ๐
