Scala Extensions

Small library of utilities related to quality that helps keeping code clear and correct.

An Optics/Lens library for purely functional manipulation of immutable objects.

General-purpose Scala libraries, including a future implementation and other concurrency tools.

Lightweight, modular, and extensible library for functional programming.

Simple refinement types with compile- and runtime checking

A clean-room implementation of a metaprogramming toolkit for Scala.

Simple, safe and intuitive Scala I/O. better-files is a dependency-free pragmatic thin Scala wrapper around Java NIO.

A macro library that converts native imperative syntax to Scalaz's monadic expressions.

A type class and dependent type based generic programming library for Scala.

A library that switches Scala code at compile-time, like #if in C/C++.

A mini Scala utility library. Compatible with functional programming beginners. Featuring validation, monad transformers, HLists, Union types.

Extensible effects are an alternative to monad transformers for computing with effects in a functional way.

Scala wrapper for Joda Time.

Fast, Scala-friendly logging bindings on top of SLF4J. Uses macros for extreme performance.

Labeled records for Scala based on structural refinement types and macros.

modify deeply nested case class fields with an elegant API

A cohesive & pragmatic framework of FP centric Scala libraries.

Large off-heap arrays (> 2GB) and mmap files.

A Scala library that is designed from the ground up for space efficiency, handling graphs with billions of nodes and edges.

A simple scala DSL to allow clean and monadic style for Play! Actions

A library to implement composable side effects, weaving typeclasses on a wrapping type and the free monad.
