It is possible to install multiple versions of Ruby on the same system. Updating Ruby using InstallersĪ newer version can be installed using third-party installers if the already installed version of Ruby is expired. The Version installed through this is the latest that would be available at that time of release. Using the yum package manager for RHEL, CentOS, and Fedora. The ruby-full package provides the old stable release on Debian and Ubuntu.
In Debian GNU/ Linux and Ubuntu, we can install Ruby as shown below: Gems work with ruby designed for a certain platform based on CPU architecture, OS of the system, and the Version.Įvery gem contains three important things. This loads the installed gems from the library folders. RubyGems is integrated with Ruby run-time loader. The installation of gems is handled easily through this. RubyGems is a package handler that provides a standard format for distributing Ruby programs. The libraries in a self-contained setup are termed “gem.” YAML, JSON, and XML are the standard library modules available.Support for Unicode and multiple character encodings.RubyGems are used as Centralized package management.The levels of variable scope are denoted by sigils such as global, class, instance, and local.Thoroughly object-oriented with inheritance and metaclasses.Exception handling and Operator overloading can be done.When everything is an object, or it has anonymous functions, closures, and continuations, with each statement having a value and functions return the last evaluation, then it is referred to Object-Oriented Programming.
Defining the functions/variables outside classes and making them part of the Object is known as Procedural Programming. When the sigil is used, it changes the semantics of the scope of the variable.
Keywords are used to define Class and Methods, whereas code blocks can be both defined by keywords or braces. It is a dynamic and general-purpose programming language. It has a dynamic type system, and memory management can be done without any intervention. It supports functional and object-oriented programming. The syntax of Ruby is similar to Perl, while the interpretation is similar to Smalltalk, but it differs considerably from Python.
