AI::Prolog is a predicate logic engine implemented in pure Perl. In predicate logic, instead of telling the computer how to do something, you tell the computer what something is and let it figure out how to do it. Conceptually, this is similar to regular expressions. The AI::Prolog distribution contains a Prolog shell called aiprolog and two short adventure games, spider.pro and sleepy.pro.
The Tcl extension provides a small but complete interface into libtcl and any other Tcl-based library for Perl programmers. It lets you create Tcl interpreters (as Perl 5 objects), bind in commands to them (either Perl subroutines or C functions dynamically loaded with the DynaLoader extension), and execute Tcl code in those interpreters.
Tiny Tcl 6.8 is a rommable, minimal Tcl implementation for embedded applications. Derived from the venerable Tcl 6.7 release, Tiny Tcl 6.8 has a solid Tcl feature set, excluding newer capabilities of Tcl 7 and 8 such as the bytecode compiler, namespaces, sockets, and async event handling, among others. Excluding C library functions, Tiny Tcl compiles down to less than 60 Kbytes on most machines, far smaller than any Tcl 7 or Tcl 8 derivatives.
xemmai is a dynamic programming language. It has lambda closures, classes, exceptions, modules, threads, and fibers. It is implemented in C++ and has a C++ friendly API to implement extension modules. It aims to be a general purpose glue language. It runs on Linux, Windows, and hopefully other Unix systems. Internally, codes are executed on a byte code interpreter. It also has a concurrent garbage collector to utilize multiple processors.
Funky is an embeddable functional programming language. It is stable, fast, and small. It includes all four dialects in a single DLL, which without optimization isless than 140 K. It can be embedded into an existing C++ application in minutes. The syntax is heavily borrowed from Lisp, because of its simplicity.
