BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures like those in Perl and JavaScript.

Expect is a program that performs programmed dialogue with other interactive programs. It is briefly described by its man page, expect(1). It uses pseudo-tty's to control the child processes, so it is not affected by programs that refuse to read from stdin or pipes. (eg: passwd(1) etc). FAQ: http://expect.nist.gov/FAQ.html

GUILE, GNU's Ubiquitous Intelligent Language for Extension, is a library that implements the Scheme language plus various convenient facilities. It's designed so that you can link it into an application or utility to make it extensible. Our plan is to link this library into all GNU programs that call for extensibility.

Io is small prototype-based programming language. The ideas in Io are mostly inspired by Smalltalk (all values are objects), Self (prototype-based), NewtonScript (differential inheritance), Act1 (actors and futures for concurrency), LISP (code is a runtime inspectable/modifiable tree) and Lua (small, embeddable).

Kawa is a full Scheme implementation written in Java. With Kawa you can access Java objects, methods, fields and classes within your Scheme code. Scheme functions and files are compiled into optimized Java byte-code, allowing you to write Java applications, applets, classes, and servlets in Scheme.

Haskell-mode is a major Emacs mode for editing Haskell source code. It provides syntax highlighting and automatic indentation and comes with inf-haskell which allows interaction with an inferior Haskell interactive loop such as the one of Hugs or GHCi. Note that if you want to use haskell-mode under XEmacs, you should install editors/xemacs-packages instead.

These are bindings to a Lua library for Ada. The gpr file is written for the version of Lua that is default on the system that builds the port. (see Mk/bsd.default-versions.mk) There is no documentation available, but two examples with sources are built and installed for illustration.

Awk scans input files for specified patterns and can perform an associated action when a line of the file matches the pattern. This is the One True version of awk described in "The AWK Programming Language" by Al Aho, Brian Kernighan, and Peter Weinberger (Addison-Wesley, 1988, ISBN 0-201-07981-X).

NBC (Next Byte Codes) is a programming language for the LEGO MINDSTORMS NXT product. NBC's syntax is based on assembler programming languages, so experienced assembler programmers (or just about any programmers) should find it very easy to get started with. Even if you aren't an experienced programmer, NBC is relatively easy to learn.
