Hi,
I'd like to announce a little project of mine that started some years ago as a C++ application and which I finally managed to port to D. It's called WildCAD and it's a simple 2D drawing program (you know - lines, circles and so on). It uses a command line interface inspired by AutoCAD and features a very immature DXF im- and export.
The application uses a DIY widget set (which comes as a sub project) called WildWidgets. Both can be found at https://gitlab.com/elvin.eu/wildcad.git and https://gitlab.com/elvin.eu/wildwidgets.git
Currently both are restricted to DMD and Linux/X11 only. Sorry for that. On the plus side just very limited dependencies are needed - mostly X11, Cairo and Cups. It's still very rough and using it can be a bit of a challenge.
Any feedback or help is appreciated ;-)
