Seed7 is a general purpose programming language. It is a higher level language compared to Ada, C++, and Java. In Seed7, new statements and operators can be declared easily. Functions with type results and type parameters are more elegant than a template or generics concept. Object orientation is used when it brings advantages and not in places when other solutions are more obvious. Although Seed7 contains several concepts of other programming languages, it is generally not considered as a direct descendant of any other programming language.
OzVM (Virtual Machine Project) is a simple, lightweight, secure virtual machine. The current target application of OzVM is OzStream, which allows platform independent self-decoding of data. The vision of OzStream is to make any and all compressed media self-extracting. OzStream abstracts compressed media from client applications, providing new freedom for users, developers, and compression techniques.
ClearParse is a flexible engine that can be used for any parsing task including interpreting or compiling programming languages, analyzing or converting data files, processing command line parameters and user input, implementing markup languages and scripts, natural language processing (NLP), and more.
PolyGen is a program for generating random sentences according to a grammar definition, that is following custom syntactical and lexical rules. Formally, it is an interpreter of a language itself designed to define languages, where to interpret means executing a source program in real time and eventually outputting its result. Here, a source program is a grammar definition. The execution consists of the exploration of such grammar by selecting a random path, and the result is the sentence built on the way.
Tcl provides a portable scripting environment for Unix, Windows, and Macintosh that supports string processing and pattern matching, native file system access, shell-like control over other programs, TCP/IP networking, timers, and event-driven I/O. Tcl has traditional programming constructs like variables, loops, procedures, namespaces, error handling, script packages, and dynamic loading of DLLs. Tk provides portable GUIs on UNIX, Windows, and Macintosh. A powerful widget set and the concise scripting interface to Tk make it a breeze to develop sophisticated user interfaces.
xpython is a bundle that includes the Python interpreter and runtime and a number of libraries. It can be compiled into a single binary, thus simplifying software distributions without proper package management. The binary contains Python, wxWindows, SQLite, and a number of useful modules.
Rhope is a dynamically typed dataflow programming language that also borrows some ideas from other paradigms. Unlike mainstream programming languages, statements are not necessarily executed in the order they are written, but instead based on their dependencies. Statements that do not share dependencies run in parallel. Most operations have value semantics (i.e. modifying an object makes a copy rather than changing the original) making this parallelism safe. For managing global state, Rhope has a transaction mechanism.
