DefinitionProvider

final class DefinitionProvider extends AnyRef

Implements goto definition that works even in code that doesn't parse.

Uses token edit-distance to align identifiers in the current open buffer with symbol occurrences from the latest SemanticDB snapshot.

The implementation logic for converting positions between the latest SemanticDB snapshot and current open buffer is quite hairy. We need to convert positions in both the "source" (where definition request is made) and the "destination" (location of the symbol definition). This requires using token edit distance twice:

- source: dirty buffer -> snapshot - destination: snapshot -> dirty buffer
