    The Panini Language

    The Panini Language

    Better Modularity, Better Concurrency

    This project makes the compiler and tools for the Panini language available. A central goal of the Panini language is to make concurrent programming easier and less error-prone. The main new feature in Panini is called a capsule. A capsule is like an actor but better because it largely retains the traditional approach for reasoning about programs as a sequence of operations, abstracts away all details of thread creation and locking, and supports fully-automatic compile-time analysis of common concurrency hazards. Panini is simple and efficient. We invite you to try it out. Downloads are available from http://paninij.org/download/

    Tepal was originally going to become an uber OO language, but during my tinkering I feel that it would be more appropriate for Tepal to become more of a meta language, allowing you to describe common development tasks in a simplified and common way.

    Vyne Compiler

    Vyne Compiler

    A compiler that compiles the Vyne programming language.

    The compiler is aimed at compiling the vyne language. The Vyne language is a high level programming language that aims to be a very powerful alternative to the currently well established high level languages. The goal is not to reinvent the wheel, but to make it better. One thing that is important is that Vyne should not be owned by anybody. The language itself should be maintained by the community. The development website can be found on http://www.vyne.org
