Ruby 2.6.3 released: updates the Unicode version to 12.1 beta

Ruby 2

Ruby is an object-oriented scripting language originally developed by Yukihiro Matsumoto (also known as Matz). The main website of the Ruby programming language is Development began in February 1993 and the first alpha version of Ruby was released in December 1994. It was developed to be an alternative to scripting languages such as Perl and Python. Ruby borrows heavily from Perl and the class library is essentially an object-oriented reorganization of Perl’s functionality. Ruby also borrows from Lisp and Smalltalk. While Ruby does not borrow many features from Python, reading the code for Python helped Matz develop Ruby.

MacOS comes with Ruby already installed. Most Linux distributions either come with Ruby preinstalled or allow you to easily install Ruby from the distribution’s repository of free software. You can also download and install Ruby on Windows. The more technically adept can download the Ruby source code and compile it for most operating systems, including Unix, DOS, BeOS, OS/2, Windows, and Linux.
