I’ve added preliminary support for #line directives to Vala. This means that the debug information of your application compiled with valac -g will now contain the filename and line number of your Vala sources, instead of the generated C sources. Vala applications can be more or less graphically debugged using Nemiver now 🙂 Mathias was kind enough to create a little demo video as the screencast tools didn’t work well on my system. There are still some issues left but it’s a start.
