I've gotta get back cracking on Clang interop. This is one of the main things I needed to do before, but that got delayed due to circumstances. I need to present an interface they can use for IR interop behind the codegen layer, then ideally, provide something like an ExternalCodegenSource you can use.
From memory and according to Trello, I fixed Clang interop so I could lay out Wide types however I like. However, this still requires a direct pointer index to find all members, which means that ABI-indirected types can't be supported with a native interface in C++.
In addition, now that I'm finished refactoring my parser, it's time to take another swing at VS extensibility and the C API. That hasn't been maintained in a long time, but I have the power to offer many more capabilities now. For example, in the past, I had to call QuickInfo every time I wanted to provide QuickInfo. Now I can offer the reverse- as in, the user provides a source location, and I can tell them what's there. I think that not only is this more efficient, but it makes for a nicer interface, and I can also provide multiple results for example if it's in a template function with many arguments. There can also be other supported functions like automated refactoring. I think that if I can demo some R# style refactoring, this would be nice.
This also implies directly that I can offer incremental re-lexing and incremental re-parsing and potentially opens a gateway into incremental re-analysis too.
