PureLogic is a Scala open source library for writing direct-style, pure business logic using context functions (aka capabilities).

It is designed to be monad-free, meaning that effects like Reader, Writer, State, and Abort compose naturally through Scala 3's given/using mechanism instead of monad transformers or for-comprehensions.

It provides an opinionated way to write pure domain logic in Scala, using a limited set of primitives.

It has zero dependencies and is available for Scala 3.3.x LTS and later versions for Scala JVM, Scala.js, and Scala Native.
