This document provides an overview and history of the Ring programming language. It discusses the motivations for creating Ring, which was to have a dynamic, small, and productive language for building applications and development environments. Ring draws influence from languages like Lua, Python, Ruby, C, C#, and BASIC. The document outlines the language's features, which include support for declarative and natural language programming, flexibility in syntax, portability across platforms, and automatic memory management.

Ring is an Innovative and practical general-purpose multi-paradigm 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 Impera- tive, Procedural, Object-Oriented, Functional, Meta programming, Declarative programming using nested structures, and Natural programming. The language is portable (Windows, Linux, macOS, 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. In this chapter we are going to discuss the goals behind the language design and implementation. 2.1 Motivation In Nov. 2011, I started to think about creating a new version of the Programming Without Coding Technology (PWCT) software from scratch. I was interested in creating multi-platform edition of the software beside adding support for Web & Mobile develop- ment. Most of the PWCT source code was written in VFP and the software comes with a simple scripting language for creating the components called (RPWI). The software contains components that support code generation in pro- gramming languages like Harbour, C, Supernova & Python. What I was looking for is a programming language that can be used to build the development environment, provides multi-platform support, more productivity, better performance, can be used for components scripting & can be used for developing different kinds of applications. Instead of using a mix of programming languages, I decided to use one programming language for creating the devel- opment environment, for components scripting & for creating the applications. I looked at many programming languages like C, C++, Java, C#, Lua, PHP, Python & Ruby. I avoided using C or C++ directly because I want high-level of productivity more than the level provided by these languages, also a language behind visual programming environment for novice programmers or professionals must be easy to use & productive. 24
- 8. Ring Documentation, Release 1.10 Java & C# are avoided for some reason too! I wanted to use a dynamic programming language and these languages are static typing, Java is multi-platform, also C# through Mono, but the use of huge number of classes and forcing the use of Object-Orientation, using a verbose language is not right for me. I need a small language, but fast and productive, also I need better control on the Garbage Collector (GC), I need a better one that is designed for fast applications. Lua is small and fast, but it’s avoided because I need more powerful language for large applications. PHP is a Web programming language and it’s syntax is very similar to C, this leads to a language not general as I want and not simple as I need to have. Python & Ruby are more like what I need, but I need something more simple, smaller, faster & productive. Python and Ruby are Case-Sensitive, the list index start counting from 0, you have to define the function before calling it, Ruby usage of Object-Orientation and message passing is more than what I need and decrease performance, Python syntax (indentation, using self, :, pass & _) is not good for my goals. All of these languages are successful languages, and very good for their domains, but what I need is a different language that comes with new ideas and intelligent implementation (Innovative, Ready, Simple, Small, Flexible and Fast). 2.2 Ring and other languages Ring is an innovative programming language that comes with better support for Natural Language Programming and Declarative Programming. The innovation comes in supporting these paradigms with new practical techniques on the top of Object-Oriented Programming and Functional Programming. Also Ring is influenced by the next programming languages • Lua • Python • Ruby • C • C# • BASIC • QML • xBase • Supernova 2.3 Special Thanks to Matz Special Thanks to Matz (Yukihiro Matsumoto - The Creator of Ruby Programming Language) for spreading the word. 2.2.

- 9. Ring Documentation, Release 1.10 2.4 History In Sept. 2013 I started the design and the implementation of the Ring programming language. After 21 months of development, In May 2015 the language Compiler & Virtual Machine were ready for use! After that I spent three months testing the language again, trying to discover any bug to fix, writing better tests, by the end of August 2015, all know bugs were fixed, Writing many tests and testing automation helped a lot in getting a stable product. In September 12, 2015, most of the documentation was written. Before releasing the language I started the marketing by writing a post in Arabic language about it to my facebook profile page asking for contributors interested in the language idea after reading a short description, In the same day I got a lot of emails from developers and friends interested to contribute! Ring 1.0 is released on January 25, 2016 Ring 1.1 is released on October 6, 2016 Ring 1.2 is released on January 25, 2017 Ring 1.3 is released on May 15, 2017 Ring 1.4 is released on June 29, 2017 Ring 1.5 is released on August 21, 2017 Ring 1.6 is released on November 30, 2017 Ring 1.7 is released on January 25, 2018 Ring 1.8 is released on June 25, 2018 Ring 1.9 is released on October 6, 2018 Ring 1.10 is released on January 25, 2019 2.4.
