Scaps is a search engine for discovering functionality in Scala libraries (or in other words, a Hoogle for Scala). You can use both type signatures and keywords in your search queries.
Use a type signature in your query and Scaps will retrieve definitions with similar types.
For example, Ordering[String] also retrieves Ordering.String which is a subtype of the query type.
When you have found a definition that seems interesting, you can directly navigate to the according Scala Doc entry by using the "Doc" link.
Scaps is an offspring of a master’s thesis by Lukas Wegmann at the University of Applied Science Rapperswil (HSR).
