    CPyrol

    an alternative interpreter for the Python programming language

    The aim of the CPyrol project is to create a complete Python interpreter written in C++ with minimal system requirements and a very clean codebase. I am working on this project mainly to gather experience with the current C++ standart (C++ 11) and with compiler development, it is not (yet) intended for practical usage. This project is at an early stage of development. Currently implemented is a Lexer, Parser and Code Generator for compiling Python code into CPython-compatible bytecode.

    The fast, flexible parsing engine. Parse anything in 4 steps: (1) define a grammar, (2) load the grammar into ClearParse, (3) call the engine to parse the source, and (4) traverse the parsing tree. You can even change your grammar at run time.

    Concurrent Object-Oriented Language

    An object oriented language for concurrent software development

    COOL is an object oriented programming language specialized for concurrent software development. Language syntax is similar to C++/C# and Java. For proper documentation please read the diploma thesis (Only available in german yet). Some of the goals to achieve: - Embedding some design-patterns on language level (singleton, state-pattern) - Implementation of a back-end for byte-code generation - Extending the compiler with an optimization phase for optimizing byte-code - Optimizing the interpreter to improve runtime performace. - Implementation of a Hotspot-Compiler for translating byte-code to x86 machine-code for native execution. - Overall optimizations of the runtime library. Supported platforms: - Windows 7 or above (32/64 bit) - x86 processor architecture COOL is designed and developed by Christian Weis since 2006. Development haltet as of 06/2015 indefinitely.

    DEPRECATED-The deva programming language

    DEPRECATED v1 - v2 is current, hosted on bitbucket

    [The deva language v1 was a learning experiment for creating an interpreted language from the ground-up, with no prior working knowledge on the subject. It makes about every mistake possible... the author went on to create a second version to apply the lessons from v1. v2 is a workable scripting language, but like all such attempts, a third version would include even more lessons (ad infinitum)] Original goal: The 'deva' programming language. A small dynamic, language bearing some similarities to C and Python. Designed for embedding in C++ applications, it is also suitable for simple scripting applications. Written to be as simple as possible.
