Yabasic implements the most common and simple elements of the basic language;
It comes with goto/gosub, with various loops, with user defined subroutines
and Libraries. Yabasic does monochrome line graphics and printing.
Yabasic runs under Unix and Windows; it is small (around 200KB) and free.
YAP is a high-performance Prolog compiler developed at
LIACC/Universidade do Porto and at COPPE Sistemas/UFRJ. Its Prolog
engine is based in the WAM (Warren Abstract Machine), with several
optimizations for better performance. YAP follows the Edinburgh
tradition, and is largely compatible with the ISO-Prolog standard and
with Quintus and SICStus Prolog.

Yorick is an interpreted programming language for:
* Scientific simulations or calculations
* Postprocessing or steering large simulation codes
* Interactive scientific graphics
* Reading, writing, and translating large files of numbers
The language features a compact syntax for many common array operations,
so it processes large arrays of numbers very quickly and efficiently.
Superficially, yorick code resembles C code, but yorick variables are
never explicitly declared and have a dynamic scoping similar to many Lisp
dialects. The yorick language is designed to be typed interactively at a
keyboard, as well as stored in files for later use.
This package includes an emacs-based development environment, which one
can launch by typing M-x yorick in emacs, if installed `yorick.el' have
been loaded into one's ~/.emacs file.
tinypy is a minimalist implementation of python in 64k of code
it includes a whole heap of features:
* parser and bytecode compiler written in tinypy
* fully bootstrapped
* luaesque virtual machine with garbage collection written in C
it's "stackless" sans any "stackless" features
* cross-platform :) it runs under Windows / Linux / OS X
* a fairly decent subset of python
o classes and single inheritance
o functions with variable or keyword arguments
o strings, lists, dicts, numbers
o modules, list comprehensions
o exceptions with full traceback
o some builtins
* batteries not included -- yet
V8 is Google's open source JavaScript engine.
V8 is written in C++ and is used in Google Chrome, the open source browser from
Google.
V8 implements ECMAScript as specified in ECMA-262, 5th edition, and runs on
Windows (XP or newer), Mac OS X (10.5 or newer), and Linux systems that use
IA-32, x64, or ARM processors.
V8 can run standalone, or can be embedded into any C++ application.

Ypsilon is an implementation of Scheme programming language for real-time
applications, which conforms to the latest standard R^6RS.
Ypsilon features mostly concurrent garbage collector optimized for systems
with multiple CPUs, and an easy to use FFI.
This is Intels C/C++ compiler, it is set up to produce native FreeBSD binaries.
A template language whose goal is reduce the syntax to the essential parts
without becoming cryptic.
Sass is an extension of CSS3, adding nested rules, variables, mixins, selector
inheritance, and more. It's translated to well-formatted, standard CSS using
the command line tool or a web-framework plugin.
