==Ruby==
Ruby is a dynamic, open-source and general-purpose object-oriented programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby supports multiple programming paradigms, including functional, object oriented, imperative and reflective. It also has a dynamic type system and automatic memory management. In Ruby, everything is an object. Every bit of information and code can be given their own properties and actions. Ruby is seen as a flexible language, since it allows its users to freely alter its parts. Ruby’s block are also seen as a source of great flexibility. A programmer can attach a closure to any method, describing how that method should act. Unlike many object-oriented languages, Ruby features single inheritance only, on purpose. But Ruby knows the concept of modules (called Categories in Objective-C). <ref> [http://www.ruby-lang.org/en/about/ http://www.ruby-lang.org/en/about/] </ref>
 
==Some Key Features of Ruby== 
<b>Interpreted</b><ref>http://www.ntecs.de/old-hp/s-direktnet/ruby_en.html</ref>
 
Advantage: Immediately executable (no waiting period while compiling)
 
Disadvantage: Execution speed much slower than with compiler (e.g. Pascal, C++)
 
 
<b>Portable</b>
 
Ruby is highly portable, so that one and the same Ruby program runs without changes under UNIX, Windows, DOS, Mac, BeOS and others. Of course that's only true unless using platform-specific modules, like for example some GUI's for UNIX or WinGKR (Win32 GUI Kit for Ruby).
 
Advantage:less expenditure (only one program had to be managed); wider distribution of the program (because it runs on serveral platforms)
 
 
<b>Untyped</b>
 
Variables in Ruby have no type, such as in Smalltalk, BASIC or Python. Variables behave as placeholders, but data is typed. In C++ or Pascal, variables are typed (e.g. int / Integer), but the data in the memory is not, that is you cannot recognize if it's a String or an Integer. In C++ or Pascal the types are checked at compile-time, whereas Ruby checks the type at runtime, so if the object understands the message (method-call) is first known after a method-call. You do not have to declare variables, because they are automatically created when you use them.
 
 
<b>Automatic memory-management (garbage collection)</b>
 
You do not have to release allocated memory in Ruby (as you have to do in Pascal/C++ with dispose/free). No longer used memory, i.e. memory-frames where no variable points to, are automatically freed by the garbage collector.
 
 
<b>Advanced OO-concepts and features</b>
 
-Singleton methods
 
-Mix-in instead of multiple-inheritance
 
-Operator overloading
 
-Method-overloading (such as C++)
 
-Exception handling
 
-Iterators and closures
 
-Meta-class
 
-Build-in pattern-matching (like Perl)

Introduction

In this Wiki, several kinds of Integrated Development Environments (IDEs) for Ruby language are shown and their features are compared.

What is Ruby

Ruby

Ruby is a dynamic, open-source and general-purpose object-oriented programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby supports multiple programming paradigms, including functional, object oriented, imperative and reflective. It also has a dynamic type system and automatic memory management. In Ruby, everything is an object. Every bit of information and code can be given their own properties and actions. Ruby is seen as a flexible language, since it allows its users to freely alter its parts. Ruby’s block are also seen as a source of great flexibility. A programmer can attach a closure to any method, describing how that method should act. Unlike many object-oriented languages, Ruby features single inheritance only, on purpose. But Ruby knows the concept of modules (called Categories in Objective-C). <ref> http://www.ruby-lang.org/en/about/ </ref>

Some Key Features of Ruby

Interpreted<ref>http://www.ntecs.de/old-hp/s-direktnet/ruby_en.html</ref>

Advantage: Immediately executable (no waiting period while compiling)

Disadvantage: Execution speed much slower than with compiler (e.g. Pascal, C++)


Portable

Ruby is highly portable, so that one and the same Ruby program runs without changes under UNIX, Windows, DOS, Mac, BeOS and others. Of course that's only true unless using platform-specific modules, like for example some GUI's for UNIX or WinGKR (Win32 GUI Kit for Ruby).

Advantage:less expenditure (only one program had to be managed); wider distribution of the program (because it runs on serveral platforms)


Untyped

Variables in Ruby have no type, such as in Smalltalk, BASIC or Python. Variables behave as placeholders, but data is typed. In C++ or Pascal, variables are typed (e.g. int / Integer), but the data in the memory is not, that is you cannot recognize if it's a String or an Integer. In C++ or Pascal the types are checked at compile-time, whereas Ruby checks the type at runtime, so if the object understands the message (method-call) is first known after a method-call. You do not have to declare variables, because they are automatically created when you use them.


Automatic memory-management (garbage collection)

You do not have to release allocated memory in Ruby (as you have to do in Pascal/C++ with dispose/free). No longer used memory, i.e. memory-frames where no variable points to, are automatically freed by the garbage collector.


Advanced OO-concepts and features

-Singleton methods

-Mix-in instead of multiple-inheritance

-Operator overloading

-Method-overloading (such as C++)

-Exception handling

-Iterators and closures

-Meta-class

-Build-in pattern-matching (like Perl)

What is an IDE

An integrated development environment (IDE) (also known as integrated design environment, integrated debugging environment or interactive development environment) is an application software that provides comprehensive facilities to computer programmers for software development. <ref>http://en.wikipedia.org/wiki/Integrated_development_environment</ref> An IDE normally consists of:

  • a source code editor
  • a compiler and/or an interpreter (computing)|interpreter
  • build automation tools
  • a debugger

Sometimes a version control system and various tools are integrated to simplify the construction of a GUI. Many modern IDEs also have a class browser, an object inspector, and a class hierarchy diagram, for use with object-oriented software development.

Eclipse is a multi-language software development environment comprising an integrated development environment (IDE) and an extensible plug-in system. It is written mostly in Java and can be used to develop applications in Java and, by means of various plug-ins, other programming languages including Ada, C, C++, COBOL, Perl, PHP, Python, R, Ruby (including Ruby on Rails framework), Scala, Clojure, Groovy and Scheme. <ref>http://en.wikipedia.org/wiki/Eclipse_(software)</ref>

Aptana RadRails

Aptana RadRails is a Rapid Application Development IDE for the Ruby on Rails framework. The goal of RadRails is to provide Ruby on Rails developers with everything they need to develop, manage, test and deploy their applications. Features include source control, code assist, refactoring, debugging, WEBrick servers, generator wizards, syntax highlighting, data tools, and much more. <ref>http://en.wikipedia.org/wiki/RadRails</ref> RadRails is now included as part of Aptana Studio 3. <ref>http://www.aptana.com/products/radrails </ref>
