Scala Extensions

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

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

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

Lightweight, modular, and extensible library for functional programming.

An extension to the core Scala library for functional programming.

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

Simple refinement types with compile- and runtime checking

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

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

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.
