Introduction

What is Ruby?

Ruby is a programming language, much like PHP, Python, or Perl. However, users of Ruby believe that this programming language has a more sophisticated and powerful syntax than other programming languages. The Ruby language seems to combine the best of all the other languages. For instance, it has Python’s ease of usability, the simplicity which Perl is famous for, and also has the conceptual elegance that Smalltalk is popular for. The Ruby language first originated in the early 1990s but has become extremely popular with programmers all over the world only in the last few years.

How to interpret IDE?

Just imagine a picture, you take off shoes and running on the beach on a sunny day. The breeze touches our face and you are free to feel the sand using your feet. But in case that there is maybe a sharpened thing which is a threat to your feet. So we need a tradeoff from direct satisfaction to safety faced. You do not need to worry about whether your feet will be scratched to bleed or something when wearing shoes. So IDE is just like the shoes and command line is just like the bare feet. It is your choice to choose between the command line and the IDE, but it is essential to know that IDE is just a name of set of tools to make it more comfortable and more easy to implement some functionality. There are many shoes brand there are there for you to choose.

IDEs are designed to maximize programmer productivity by providing tightly-knit components with similar user interfaces. This should mean that the programmer has to do less mode switching versus using discrete development programs. However, because an IDE is a complicated piece of software by its very nature, this higher productivity only occurs after a lengthy learning process. Most IDEs have tools that allow you to:

  • Write and edit source code
  • See errors as you type
  • See highlighted code syntax
  • Automate repetitive tasks
  • Compile code
  • Browse class structures
  • View JavaDocs
  • Use drag-and-drop utilities for easy building of features, such as graphic objects or creating database connections

The mostly used IDE are: Aptana RadRails, Ruby Mine, Eclipse, and NetBeans. You may find more information : IDE.
