Daniela Robles (Guest) on 2012-11-11 20:58 Hi all, Ruby no longer comes together with SciTE, so I had to download the SciTE text editor separately. However, I find that Ruby and ScITE do not work together.
The command line in Ruby won't run or find any programs that I create with the text editor. How do I get them to work together? Or how do I get Ruby to find and locate programs and scripts I write with SciTE? Carlo E.

Please log in before posting. RubyInstaller for Windows. Introduction to Ruby. Ruby is a powerful, flexible programming language you can use in web/Internet development, to process text, to create games, and as part of the popular Ruby on Rails web framework. Ruby is: High-level, meaning reading and writing Ruby is really easy—it looks a lot like regular English! Interpreted, meaning you don't need a compiler to write and run Ruby. You can write it here at Codecademy or even on your own computer (many are shipped with the Ruby interpreter built in—we'll get to the interpreter later in this lesson).Object-oriented, meaning it allows users to manipulate data structures called objects in order to build and execute programs.
We'll learn more about objects later, but for now, all you need to know is everything in Ruby is an object.Easy to use. This course assumes no previous knowledge of Ruby in particular or programming/computer science in general. Coursera. Object Oriented Ruby. Ruby is pure object-oriented language and everything appears to Ruby as an object. Every value in Ruby is an object, even the most primitive things: strings, numbers and even true and false. Even a class itself is an object that is an instance of the Class class. This chapter will take you through all the major functionalities related to Object Oriented Ruby. A class is used to specify the form of an object and it combines data representation and methods for manipulating that data into one neat package. The data and methods within a class are called members of the class. Ruby class definition: When you define a class, you define a blueprint for a data type. A class definition starts with the keyword class followed by the class name and is delimited with an end.
Class Box code end The name must begin with a capital letter and by convention names that contain more than one word are run together with each word capitalized and no separating characters (CamelCase). Define ruby objects: #! #! #! #! #! Ruby Classes and Objects. Ruby is a perfect Object Oriented Programming Language. The features of the object-oriented programming language include: Data Encapsulation: Data Abstraction:Polymorphism:Inheritance: These features have been discussed in Object Oriented Ruby. An object-oriented program involves classes and objects. A class is the blueprint from which individual objects are created.
In object-oriented terms, we say that your bicycle is an instance of the class of objects known as bicycles. Take the example of any vehicle. A vehicle can also have certain functions, such as halting, driving, and speeding. A class Vehicle can be defined as: Class Vehicle{ Number no_of_wheels Number horsepower Characters type_of_tank Number Capacity Function speeding { } Function driving { } Function halting { }} By assigning different values to these data members, you can form several instances of the class Vehicle. Defining a Class in Ruby: class Customerend You terminate a class by using the keyword end. Example: #! Hello Ruby!
