Language Workbench in Visual Studio

This is far from polished and complete but here you can see the grammar defined in foo.g being dynamically compiled and used to parse the text in the grammar console. You can see how the [Keyword] attribute is used to generate syntax highlighting in that grammar window also, as well as automatic error generation for the errant ‘!’.

Next up is visualization of the node graph produced by the parse as well as error information. Very promising progress though!
