If you know Ring, please write code for some of the tasks not implemented in Ring.
The Ring programming language is an Innovative and practical generalpurpose multiparadigm scripting language that can be embedded in C/C++ projects, extended using C/C++ code and/or used as standalone language. The supported programming paradigms are Imperative, Procedural, ObjectOriented, Functional, Meta programming, Declarative programming using nested structures, and Natural programming. The language is portable (Windows, Linux, Mac OS X, Android, etc.) and can be used to create Console, GUI, Web, Games and Mobile applications. The language is designed to be Simple, Small, Flexible and Fast. Its Dynamic Language (Dynamic Typing and Weakly Typed) that compile the source code to byte code then execute it by the Ring Virtual Machine, which is integrated with the Ring Compiler in one program. The first version of the language (around 100,000 lines of C/C++/Ring code) is released on January 25th, 2016
The language is simple, trying to be natural, encourage organization and comes with transparent and visual implementation. It comes with compact syntax and a group of features that enable the programmer to create natural interfaces and declarative domainspecific languages in a fraction of time. It is very small, fast and comes with smart garbage collector that puts the memory under the programmer control. It supports many programming paradigms, comes with useful and practical libraries. The language is designed for productivity and developing high quality solutions that can scale.
Designed for a Clear Goal
Applications programming language. Productivity and developing high quality solutions that can scale. Small and fast language that can be embedded in C/C++ projects. Simple language that can be used in education and introducing Compiler/VM concepts. GeneralPurpose language that can be used for creating domainspecific libraries, frameworks and tools. Practical language designed for creating the next version of the Programming Without Coding Technology software.
