- Added APIs to retrieve an `ITextBuffer` from a `Document` and to retrieve a `RazorCodeDocument` from an `ITextBuffer`.
- The `RazorCodeDocument` from `ITextBuffer` API supports both the new and old Razor parsers so we can transition seamlessly between the two.
- Added logic in the `RazorDirectiveCompletionProvider` to consume descriptions from `DirectiveDescriptor`s. This is then surfaced via tooltips.
- Retrieved currently active `RazorCodeDocument` given a Roslyn buffer and harvested all directives to display in the completion list.
- Added unit tests to validate each new services functionality.
#291
I've stripped out some of the dead code and complexity from the document
tracker in an attempt to simplify it. I will bring this back as part of
the multi-targeting work.
- Renamed `RazorEditorParser` => `VisualStudioRazorParser` (maintained a copy of the original in Legacy)
- Tried to make as little changes as possible to the `BackgroundParser` due to its complexity; mostly just removed the TreeStructureChanged logic since this is re-done on the Razor editor side of things.
- Split the `RazorEditorParserTest`s into two separate tests. Partial parser tests and the VS parsing tests.
- Updated `StringTextSnapshot` to support changes in order to test the VS parser.
