Open Source Scala Software for BSD

Caliban is a purely functional library for building GraphQL servers and clients in Scala. The design principles behind the library are the following. Minimal amount of boilerplate: no need to manually define a schema for every type in your API. Pure interface: errors and effects are returned explicitly (no exceptions thrown), all returned types are referentially transparent (no Future). Clean separation between schema definition and implementation: schema is defined and validated at compile time using Scala standard types, resolver (RootResolver) is a simple value provided at runtime. All interfaces are pure and types are referentially transparent. Schemas are type safe and derived at compile time. No need to manually define a schema for every type in your API. Let the compiler do the boring work. Out-of-the-box support for major HTTP server libraries, effect types, Json libraries and more.

The opinionated microservices framework for moving away from the monolith. Lagom helps you decompose your legacy monolith and build, test, and deploy entire systems of Reactive microservices. Lagom is an open source framework for building systems of Reactive microservices in Java or Scala. Lagom builds on Akka and Play, proven technologies that are in production in some of the most demanding applications today. Lagom's integrated development environment allows you to focus on solving business problems instead of wiring services together. A single command builds the project, starts supporting components and your microservices, as well as the Lagom infrastructure. The build hot-reloads when it detects changes to source code.

The Mozart Programming System is an open source implementation of the programming language Oz 3. Oz is a multi-paradigm language that supports declarative programming, object-oriented programming, constraint programming, concurrency and distributed programming as part of a coherent whole.

DataNucleus provides Java data persistence to a range of datastores using JDO/JPA/REST APIs. *** Note that code development is no longer on SourceForge (code on SourceForge is for versions up to 3.3.5 only) ***

NeoDatis ODB is a new generation Object Oriented Database. ODB is a real native and transparent persistence layer for Java, .Net, Groovy, Scala and Google Android. ODB is very simple and very fast and comes with a powerful query language.

LumberJack4Logs is a viewer for log and trace files with the ability to extend the recognized data formats by adding text parser plugins.

An asynchronous file viewer for large files (100 of MBytes, GBytes)

DLNA server (multiplatform) for personal computers with support of high resolution DSD, FLAC and WAV files (OGG, WMA and MP3 is also supported). Stream your personal files to various stream players using LAN or wireless WLAN (Wi-Fi).

Simuquant is made to construct and simulate universal quantum circuits. It's GUI enables intuitive access and direct graphical feedback, making it useful in a classroom situation and the like. Simulation processing is done in parallel, utilizing parallel collections introduced in scala 2.9. This application has been created as part a bachelor-thesis at the Hamburg University of Applied Sciences. The thesis is available at: http://opus.haw-hamburg.de/volltexte/2012/1843/pdf/ba_dahl.pdf Future plans: - Operator grouping (enables repeated blocks) - Editable library

A 2d rpg game engine created to be ease of use. Built in Scala and libgdx. Also our community forums http://rpgboss.forumatic.com

GhostTrap is a classic 3-in-a-row puzzle game (like Zookeeper / Bejuweled) written in the Scala programming language on top of the JVM

To convert my Scala unit tests to Kolin unit tests as Scala is a pain to upgrade and I'm stock at Scala 1.12. Easier to move to Kotlin which also works fine with Android.

This domain specific language lets you declare complex java objects with a Json-like notation. In addition to that, it lets you specify in a natural way what the mockito mocks should return when called with a given value.

This project is no longer hosted on sourceforge, please go to https://github.com/jodersky/sims instead. A library for rigid body simulation written in Scala. This project was created under the terms of a one-year project at school (Gymnase de Burier). Another program for testing and visualizing SiMS, Graphyx, is included.

An Interactive Fiction Player written for Java Virtual Machine. It implements the Z-machine and Glulx specifications and can be used either standalone or as an applet. The Z-Code/Glulx interpreter runs adventures made by Infocom and contemporary Inte

Provides the ability to export playlists from an iTunes Music Library. Supports exporting playlists as m3u files. 1.x branch built using .NET. 2.x branch build using Flex (AIR) and Scala.

A novel database and a webtop based on a new theory of objects.

The Alpakka project is an open source initiative to implement stream-aware and reactive integration pipelines for Java and Scala. It is built on top of Akka Streams and has been designed from the ground up to understand streaming natively and provide a DSL for reactive and stream-oriented programming, with built-in support for backpressure. Akka Streams is a Reactive Stream and JDK 9+ java.util.concurrent.Flow-compliant implementation and therefore fully interoperable with other implementations. As Kafka’s client protocol negotiates the version to use with the Kafka broker, you may use a Kafka client version that is different than the Kafka broker’s version.

This program shall implement some rule systems for ants. Special interest is to do researches about the conflict behaviour. The project is written with the mason-library (page: http://cs.gmu.edu/~eclab/projects/mason/ ) and mainly with the scala programming language

Assorted projects. General-purpose libraries for Python, C++, Scala, bash, and others. Meta-programming tools. System utilities. UI components. Web APIs. Configuration files. Benchmarks. Programming competition entries. And much more.

The asyncobjects framework is intendend for implementing event-driven network applications. It provides higher level API if compared with Java NIO. Initial code is based asyncobjects prototype from sebyla.sf.net project.

Binding.scala is a data-binding library for Scala, running on both JVM and Scala.js. Binding.scala can be used as the basis of UI frameworks, however latest Binding.scala 12.x does not contain any build-in UI frameworks anymore. For creating reactive HTML UI, you may want to check out html.scala, which is a UI framework based on Binding.scala, and it is also the successor of the previously built-in dom library. See also React / Binding.scala / html.scala Interoperability for using existing React components with Binding.scala. Regular HTML does not compile unless developers manually replace class and for attributes to className and htmlFor, and manually convert inline styles from CSS syntax to JSON syntax.

An application for managing your (e)Book collection.

What is a plug-in architecture? Simply speaking, it is a framework that will allow a program to "look for" add-in functionality at startup, and then allow that plug-in to cooperate with itself. CATCore (Component Architecture Toolkit, Corelib) is this and more. With CATCore you can load plugins that run in there own thread(Actor) and communicate with each other via messages. But also applications can forward messages to other applications. So plugsins loaded in one app can communicate with plugins running in another app.
