A Python extension embedding SWI-Prolog PyProlog is a Python extension that permits direct access to an embedded PROLOG. The extension lends Python the efficient unification and backtracking of PROLOG, and allows a programmer to instrument Python classes with PROLOG code. Callbacks from PROLOG to Python are also supported.

Quack enhances Emacs support for Scheme programming. Quack is layered atop the standard packages `cmuscheme.el', by Olin Shivers, and `scheme.el', by Bill Rozas and Dave Love.

RegUtil is an implementation of IBM's RexxUtil for Regina. According to the author, it is not complete; however, it implements a large number of the RexxUtil functions, and is very useful. Note that any scripts which load RegUtil must be run with the 'regina' command, rather than 'rexx'; the latter does not support the use of external function packages.

The documentation for the Scala standard library.

Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages, enabling Java and other programmers to be more productive. Code sizes are typically reduced by a factor of two to three when compared to an equivalent Java application.

StarLogo is a specialized version of the Logo programming language written in Java. See: For more details.

SketchyLISP is an embeddable interpreter for a purely applicative dialect of Scheme. It may be considered an implementation of pure LISP plus global definitions and some input/output functions. This package contains the SketchyLISP interpreter and library, the manual, and example programs.

From the web site: Tuareg is a Caml mode for GNU Emacs and XEmacs. It handles automatic indentation of OCaml and Camllight codes. Key parts of the code are hilighted using Font-Lock. Support to run an interactive Caml toplevel and debbuger is provided. This mode attempts to give better results than the one provided in the standard distribution of OCaml. Indentation rules are slightly different but closer to classical functional languages. There is no relation with the Tuareg People, except their reputation of great CAMEL riders and breeders. Documentation is installed into share/doc/tuareg-mode

ATLAST is an attempt to make software component technology and open architecture applications commonplace in the mainstream software market. It is both a software component which can be readily integrated into existing applications, providing them a ready-made macro language and facilities for user extension and customisation and, at the same time, it is a foundation upon which new applications can be built in an open, component-oriented manner.
