A mini Scala utility library. Compatible with functional programming beginners. For the JVM and Scala.js.
It may help you understand how to use - and how to implement (looking at the code) - some popular functional programming features. Il also provides some useful utilities.
Hamsters is built for Scala 3 (3.3.x LTS) and cross-compiled for the JVM and Scala.js. The LTS line keeps it usable from Scala 2.13 projects thanks to TASTY/binary compatibility.
Currently, Hamsters supports :
-
Data validation
-
Default values for options (orEmpty)
-
Enum typeclass
-
Future Squash (simplifications for nested types)
-
Lens
-
mapN
-
Memoization
-
Monad transformers
-
NonEmptyList
-
Retry
-
Show (better toString)
