Ruby Programming Language


ruby programming language

When you embark on your developing journey you will find out that it won't take you long before you get your hands dirty.

Programmers don't usually spend a lot of time thinking about the scope of their application because they usually already know the purpose of developing their applications in the first place or work for a place that know what they would like the programmer to build for them.

When you realize the real reason why you would like to develop an application and you are ready to put in some work, time and determination; you will be able to be the best programmer that you couldn't even imagine of being.

In today's article we are going to talk about the Ruby programming language and the complexities of the language that makes it very useful among many web developers.

A Japanese named Yukihiro Matsumoto developed the Ruby programming language in 1993, because he wanted to combine parts of Perl, Python, Lisp, Ada, Eiffel and Smalltalk into a more complex language we all know as Ruby.

The Ruby programming language is a natural programming language, it is not as simple as it may appear to be, when you first look at it.

Ruby has grown tremendously since its inception in 1993, its popularity also grow very fast when you compare the growth rate of this programming language to other programming languages.

The web sites as well as the applications written with the Ruby programming language has led many programmers to believe that Ruby is the best language of choice to develop their applications and web framework.

You can download, use, copy, modify and distribute the Ruby programming language free of charge as well and you have created a very useful application using Ruby.

Ruby was developed with the idea of being more powerful than any other object-oriented language that already existed, such as Perl.

The creator of Ruby was concerned with making the Ruby programming language more object-oriented than any other programming language.

In Ruby every bit of code or information you write can be given their own properties and actions because everything in Ruby is based on the object-oriented syntax that we all know very well.

If you don't know object-oriented then email me or leave us a comment and we'll be sure to give you a response as soon as we hear from you.

Anyhow, Ruby allow its users to alter its parts freely, because it is a very flexible language, which can be easily used to demonstrate your true programming abilities.

In the Ruby programming language you are not restricted as a coder because essential parts and existing parts can be removed, redefined, and added upon.

You could easily add to Ruby's bulletin numeric class in Ruby as well, because of the flexibility of the Ruby programming language.

My fellow readers the journey will not be easy but it will be finished, in time and at the right time when everything is ready you will see your skills become very sharp, but you must not quit though, for if you quit you will lose your chance of arriving to your better tomorrow and accomplishing your application development ambitions.

One of our programming and applications development ambition is this website that we developed because we want to help you the developer achieve that application that you so much desire.

You will find that through here you will become a better programmer, because you'll learn to see programming from a different point of view.

Anyhow, let's get back to the fact of the matter, Ruby is used to write Common Gateway Interface (CGI) scripts, it is very easy to understand because it has a syntax that is very clean, which allow developers such as you, the ability to understand the Ruby programming language.

You can also use Ruby to be embedded into Hypertext Mark up Language (HTML) web pages.

As a general-purpose language Ruby share some similarity in syntax with C++, Perl and many other programming languages.

You can easily maintain a Ruby programming language because applications created with Ruby are very much scalable.

By scalability we mean that you'll be able to upgrade your Ruby application very easily and without it being a nightmare.

Many GUI tools such as Tcl/Tk, GTK, and OpenGL are all supported by Ruby, but you would have to be very experienced in programming using Ruby to be able to use it with such GUI tools.

Databse2, MySQL, Sybase and Oracle can be easily accessible using the Ruby programming language as well.

Ruby scripts use many built-in functions, that can be of help when you are developing your application, which should bring value to your users.

If you want to begin to program using the Ruby programming language, the very first thing you'll have to do is to create an environment on your computer to write your code and execute it so that you can see your creation in action on your computer.

In order for you to install Ruby, you would need to go to their website and download a fresh copy of the Ruby package or use many of the tools that they have on their website and follow the guidelines described on the website for you to be able install the Ruby programming language on your computer.

On Linux/Ubuntu you would use this line on the terminal, “$ sudo apt-get install ruby-full” to be able to install a copy of Ruby on your computer.

Once you have created an environment for your newly created application that was developed using Ruby, you are now ready to start coding on Ruby.

Before you get into all of that coding, though let's talk a bit more about the programming language so that you may become an expert of the Ruby programming language.

Objects are always used in order to make things work in Ruby, because integers, text, arrays and characters and everything else in Ruby is an object.

In Ruby you'll be able to create objects that have conversations with other objects so that they can do things you desire for your application.

In object-oriented programming objects are an integral part, and because Ruby is a true object-oriented programming language, you'll have to master the art of role-playing as an object on your applications.

Objects in Ruby are also able to interact with each other, because they can use each other's methods.

You would have to be able to invoke methods of other objects using objects with additional information to obtain an appropriate response.

The additional information you provide to methods of other objects are known as argument to a method.

The methods of objects in Ruby are path of communications between the objects so that they may use each other's methods.

Ruby's version of object-oriented is very well defined and more detailed than most object-oriented programming languages.

When you are invoking a method of an object, you'll have to put a dot after the object that is invoking the method of another object.

In puts( "hello world".

uppercase ), the string hello world is invoking the method uppercase to display the string hello world in uppercase.

Everything in Ruby is an object and everything can be manipulated by methods of another object when you use the objects the right way.

The results of that which come out of that manipulation by other objects are themselves objects as well, because everything in Ruby is an object.

You as a developer is usually going to use Ruby to be able to model concepts that are being applied in the real world.

In your code you will always have to represent the categories of things that you want to model from the real world, during your modeling process or while you formulate your logic for the code.

In order for you to be able to represent the categories, you define during your modeling process in your mind, you would have to define a class to represent these entities.

A combination of methods or methods that use other methods is known as a class in the Ruby programming language.

Once you have your class also known as object, created, you would invoke this object using a constructor.

A constructor in object-oriented programming language is a special type of subroutine used to create an object using the standard constructor .new.

In Ruby unlike most programming languages you don't need to add semicolons (;) at the end of each line of code.

The code layout of your application also depends on your taste and style of coding, because you don't have to worry about indentation in Ruby, because it is not significant.

However, do have some type of well maintained code style, because many programmer are judged by their indentation on their code and style of coding.

If your code does not look to be clean with a programming language that is supposed to have a clean syntax, then you will have a tough time making friends within the programming community, including in the Ruby community; because many programmers prefer looking at a piece of code that they can easily understand.

If you want to become a master programmer you will have to learn to embrace the work that comes before you become that programmer.

If you don't learn to master the art of doing the work then you can forget about becoming a master programmer you will never reach that level.

Maybe you will, anyways back to the fact of the matter; Ruby is an open-source and is freely available on the Web, but it is subject to a license. Ruby is a general-purpose, interpreted programming language.

Ruby is a true object-oriented programming language.

Ruby is a server-side scripting language similar to Python and PERL.

Ruby can be used to write Common Gateway Interface (CGI) scripts.

Ruby can be embedded into Hypertext Markup Language (HTML).

Ruby has a clean and easy syntax that allows a new developer to learn very quickly and easily.

Ruby has similar syntax to that of many programming languages such as C++ and Perl.

Ruby is very much scalable and big programs written in Ruby are easily maintainable.

Ruby can be used for developing Internet and intranet applications.

Ruby can be installed in Windows and POSIX environments.

Ruby support many GUI tools such as Tcl/Tk, GTK, and OpenGL.

Ruby can easily be connected to DB2, MySQL, Oracle, and Sybase.

Ruby has a rich set of built-in functions, which can be used directly into Ruby scripts. Quite often, you won’t even need to download Ruby. It now comes preinstalled on many Linux distributions, and Mac OS X includes Ruby (although the version of Ruby preinstalled on OS X is normally several minor releases behind the current Ruby version). Try typing ruby -v at a command prompt—you may be pleasantly surprised. Once you have Ruby installed on your computer, then you will be able to program using Ruby, and you will have a lot of fun. Please let us know, how it goes and if you had any problems, programming using Ruby, because we know you'll encounter them, but we'd like to encourage you and wish you the best.
