* Fix #248 and #250 This fixes hover for types, classes and type variables. Information about spans includes a `Maybe Type` which is `Just` for data-level expressions and `Nothing` for type-level expressions. `AtPoint.atPoint` which is the oddly-named function responsible for constructing hover information, runs in the `Maybe` monad, and aborted at the first sight of a `Nothing`, thus producing no hover information for type-level spans. In the process of fixing this, I have refactored the function to + separate the construction of data-level and type-level hover info + make the components that make up the hover info (and their construction) more clear I can see plenty little improvements that could be made to the functionality of the code (and lots that could be made to its organization), but the most important fixes of the basic missing functionality are here. Fix #248 Fix #250 * Revert behaviour of locationsAtPoint to match its name The name suggests that it returns all locations, while the last commit changed this to return at most one. * Fix issue numbers in test titles There was some confusion about which tests addressed issue 248 vs 249 |
