HGL is a compiler/interpreter suite for developing images. It features its own simple but powerful language, an output format configurable by plugins, runtime input handled by plugins, and easy integration into various environments like Web servers or graphical applications. The input is taken from a source file, which has to be compiled for quick and frequent access by the interpreter. An interpreter then runs the compiled files, takes input from custom plugins (if neccessary), and outputs its result via custom plugins.
PH7 is an in-process software library that implements a highly-efficient embeddable bytecode compiler and a virtual machine for the PHP programming language. It implements most PHP 5.3 constructs, including heredoc, nowdoc, gotos, classes, anonymous functions, and closures, along with powerful extensions such as function overloading, comma expressions, full type hinting, string comparison operators, and more. It is the ideal library for enhancing your application or device (such as router or set-top box) with dynamic Web interfaces, with the benefits and power of PHP and without the overhead incurred by process creation. As an embedded interpreter, it allows multiple interpreter states to coexist in the same program, without any interference between them.
Alore is an object-oriented programming language with a clean syntax that resembles Python and Lua. It is optionally-typed like Google Dart. It is both a dynamic scripting language and a general-purpose language with static typing. It is aimed at most programming tasks, from short scripts to complex applications. It allows programmers to freely mix static and dynamic typing within a program. It has native threads and a very fast edit-test cycle. Programmers can always bypass type checking and run their programs immediately.
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.
