Ruby is the interpreted scripting language for quick and easy object-oriented programming. It has many features to process text files and to do system management tasks (as in Perl). It is simple, straight-forward, extensible, and portable.
We also support Ruby on Rails, a popular open-source web framework.
Common Paths:
- /usr/bin/ruby
- /usr/local/bin/ruby
Features of Ruby
 |
Ruby has simple syntax, partially inspired by Eiffel and Ada. |
|
Ruby has exception handling features, like Java or Python, to make it easy to handle errors. |
|
Ruby's operators are syntax sugar for the methods. You can redefine them easily. |
|
Ruby is a complete, full, pure object oriented language: OOL. This means all data in Ruby is an object, not in the sense of Python or Perl, but in the sense of Smalltalk: no exceptions. Example: In Ruby, the number 1 is an instance of class Fixnum. |
|
Ruby's OO is carefully designed to be both complete and open for improvements. Example: Ruby has the ability to add methods to a class, or even to an instance during runtime. So, if needed, an instance of one class *can* behave differently from other instances of the same class. |
|
Ruby features single inheritance only, *on purpose*. But Ruby knows the concept of modules (called Categories in Objective-C). Modules are collections of methods. Every class can import a module and so gets all its methods for free. Some of us think that this is a much clearer way than multiple inheritance, which is complex, and not used very often compared with single inheritance (don't count C++ here, as it has often no other choice due to strong type checking!) |
|
Ruby features true closures. Not just unnamed function, but with present variable bindings. |
|
Ruby features blocks in its syntax (code surrounded by ' ... ' or 'do' .. 'end'). These blocks can be passed to methods, or converted into closures. |
|
Ruby features a true mark-and-sweep garbage collector. It works with all Ruby objects. You don't have to care about maintaining reference counts in extension libraries. This is better for your health. ;-) |
|
Writing C extensions in Ruby is easier than in Perl or Python, due partly to the garbage collector, and partly to the fine extension API. SWIG interface is also available. |
|
Integers in Ruby can (and should) be used without counting their internal representation. There *are* small integers (instances of class Fixnum) and large integers (Bignum), but you need not worry over which one is used currently. If a value is small enough, an integer is a Fixnum, otherwise it is a Bignum. Conversion occurs automatically. |
|
Ruby needs no variable declarations. It uses simple naming conventions to denote the scope of variables. Examples: simple 'var' = local variable, '@var' = instance variable, '$var' = global variable. So it is also not necessary to use a tiresome 'self.' prepended to every instance member. |
|
Ruby can load extension libraries dynamically if an OS allows. |
|
Ruby features OS independent threading. Thus, for all platforms on which Ruby runs, you also have multithreading, regardless of if the OS supports it or not, even on MS-DOS! ;-) |
|
Ruby is highly portable: it is developed mostly on Linux, but works on many types of UNIX, DOS, Windows 95/98/NT, Mac, BeOS, OS/2, etc. |
