    Seed7

    Interpreter and compiler for the Seed7 programming language.

    Interpreter, compiler, libraries, documentation and examples for the Seed7 programming language. Seed7 is a general purpose programming language. It is a higher level language compared to Ada, C/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 where it brings advantages and not in places where other solutions are more obvious. Seed7 spares no effort to support portable programming. Several driver libraries assure that the access to operating system resources such as files, directories, network, clock, keyboard, console and graphics are done in a portable way. Although Seed7 contains several concepts from other programming languages, it is generally not considered a direct descendant of any other programming language.

    Ficl - small systems scripting with OO
    Ficl is a lightweight, embeddable scripting language designed to be incorporated into other programs, and especially embedded systems that may have memory and OS constraints. Applications include scripting, hardware bring-up, rapid prototyping, and system extensions. Unlike Lua or Python, Ficl acts as a component of your system - you feed it stuff to do, it does the stuff, and comes back to you for more. You can export compiled code to Ficl, execute Ficl code from your compiled code, or interact. Your choice.

    Breeze

    eXtensible Stack Based Language

    Breeze is a general-purpose stack-based programming language. The main feature of the language is that the concepts of stack and dictionary are no longer distinct. In fact, dictionary words are replaced by named stacks. The process of defining a word is replaced by "pushing" onto a named stack, and that of executing a word is replaced by "popping" from a named stack. A named stack is called an application. Data and code can be moved between applications by using operations (i.e. other applications) that make use of a default stack as an intermediate. In principle, the language recognizes only numbers that can be organized into lists, which are the only form of aggregation of data/code.

    This is an interpreted programming language that is designed to teach young children the fundamentals of programming, hiding away from students the complex concepts of programming, such as parentheses, quotes, data types, arrays, while allowing them to understand the basic concepts of programming, and, move to a more advanced language. It also serves as an exapmle on how to create an interpreter with QBASIC. The interpreter is written in QBASIC, and is licensed under the GNU GPLv2. About the unixname: The "shortname" of the project was a typo, but it was too late when I actually realised it. Features that still need to be implemented: Boolean expressions (IF) (If I ever find a flexible way to implement them, because you can't parse user input to a boolean command in QBASIC, without using a dynamically changed BAS file, which is going to fail if using it compilled) The source code should be compiled with either QB64, QuickBASIC or freeBASIC (with the -lang qb switch enabled
