Scala Extensions

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

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

An extension to the core Scala library for functional programming.

Simple refinement types with compile- and runtime checking

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

Lightweight, modular, and extensible library for functional programming.

Safe, easy, filesystem operations in Scala as convenient as in the Bash shell.

Practical logging framework that doesn't depend on any other logging framework and can be completely configured programmatically.

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

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

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

A Scala library with basic graph functionality that seamlessly fits into the Scala standard collections library.

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

First class syntax support for type classes in Scala.

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

A macro to replace Scala enumerations with a sealed family of case objects. This allows additional checks for the compiler, e.g. for missing cases in a match statement. Has additinal support for Json libraries and the Play framework.

Scala wrapper for Joda Time.

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

An asynchronous programming facility for Scala.

A cohesive & pragmatic framework of FP centric Scala libraries.

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

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

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

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

Easy way to create Free Monad using Scala macros with first-class Intellij support.

modify deeply nested case class fields with an elegant API

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

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

Tiny publish subscribe library

A library to define common interfaces for different Id types.

A library to optimize fetching immutable data structures from several endpoints in several formats.

Lightweight lens library in less than 50-lines of Scala.

A library to speed up Scala collection operations by removing runtime overheads during compilation, and a custom data-parallel operation runtime.

a collection of libraries for common, everyday programming tasks (I/O, JSON, i18n, etc.)

Comprehensive logging library for Scala.

A Scala date library for date and schedule generation.

Asynchronous programming in fully featured Scala syntax.

A library for enhancing your application logs with colors and source code locations.
