For comments and corrections, or to propose something to be included in the list, please send a mail. I do not take any guarantee about the quality of software referenced here. Use at your own risk. Links that currently point to nowhere now carry a icon. I want to say a big thanks to all those people that pointed me to new systems to include here. It is amazing that not only the authors themselves help to keep this list as complete as possible, but also people that come across something interesting.

Gremlin is a domain specific language for traversing graphs. Graphs are data structures where there exists vertices (i.e. dots, nodes) and edges (i.e. lines, arcs). Gremlin was designed to work with a type of graph called a property graph. Property graphs are defined, in detail, in the Defining a Property Graph section of this documentation. By using Gremlin, it is possible make use of a REPL (command line/console) to interactively traverse a graph.
Blockly is a web-based, graphical programming editor. Users can drag blocks together to build an application.
Compiler for the Tiger Programming Language. From the reference manual on Tiger: “This document describes the Tiger language defined in Andrew Appel’s book Modern Compiler Implementation in Java (Cambridge University Press, 1998). The Tiger language is a small, imperative language with integer and string variables, arrays, records, and nested functions. Its syntax resembles [...]
tortuguita is a Logo interpreter implemented in Java
Frege is a non-strict, pure functional programming language in the spirit of Haskell. It enjoys a strong static type system with type inference. Higher rank types are supported, though type annotations are required for that. Frege programs are compiled to Java and run in a JVM. Existing Java Classes and Methods can be used [...]
In the Genyris programming paradigm objects can belong to multiple classes independent from construction. Indentation reduces parentheses yet retains the power of Lisp. External Java libraries can be imported.
QuiXProc is an open source implementation of XProc. The authors want QuiXProc to become a mainstream tool to process Structured and Unstructured Data, preserving high quality, high throughput, and low resources consumption.
