Ruby is a powerful and dynamic open source, object-oriented language that started developing in 1993. It runs on several platforms, as well as UNIX and lots of types of UNIX system, MS-DOS, Windows 9x/2000/NT, BeOS, and MacOS X.

Ruby’s primary focus is productivity of program development, and users can realize that programming in R-uby is productive and even fun. R-uby is similar temperament for the matter domains like these:

Text processing—R-uby’s File, String, and Regexp categories assist you method text knowledge quickly and cleanly.

CGI programming—R-uby has everything you would like to try to to CGI programming, as well as text-handling categories, a CGI library, info interface, and even eR-uby (embedded R-uby) and mod_r-uby for Apache.

Network programming—Network programming may be fun with R-uby’s well-designed socket categories.

GUI programming—GUI outfit interfaces like R-uby/Tk and R-uby/Gtk ar out there.

XML programming—Text-handling options and therefore the UTF-8-aware regular expression engine create XML programming handy in R-uby. The interface to the expat XML programme library is additionally out there.

Prototyping—With its high productivity, R-uby is usually wont to create prototypes. Prototypes generally become production systems by commutation the bottlenecks with C written extensions.

Programming education—You will teach students that programming is fun

Now ar you a lot of fascinated by R-uby? you will find out a lot of during this article. R-uby is known as once the red jewel; it is not AN signifier. I selected the name of the language from the jewel name, influenced by Perl. though I named R-uby rather by coincidence, I later realised that r-uby comes right once pearl in many things, as well as birthstones (pearl for June, r-uby for July) and font sizes (Perl is 5-point, R-uby is 5.5-point). i assumed that it solely created sense to use R-uby as a reputation for a scripting language that was newer (and, hopefully, better) than Perl.

R-uby has adopted varied options from several languages, as well as Perl, Lisp, and Smalltalk, and it’s become a unique language than the others. Let ME sketch R-uby by scrutiny it with different languages.

Smalltalk
Like Smalltalk R-uby could be a dynamic and pure object-oriented language. each languages ar dynamic as a result of they are doing not use static sort data. {they ar|they’re} pure as a result of all values ar objects and ar classified into categories that are objects themselves. each are designed to be object-oriented languages from the start, and that they each support trash pickup.

In Smalltalk, management flow structures like conditionals ar done by causation messages to the objects—at least, that is however it seems. generally this makes Smalltalk programs unnatural and arduous to browse.

In Ruby, management flow structure is way a lot of conservative. Smalltalk is AN software system and a programming setting. The program is largely a picture inside the setting that’s created through interaction via browsers. not like Smalltalk programs, R-uby programs ar clearly separated from the language and its interpreter.

R-uby and 2 different nice “P” languages (Perl and Python) typically ar classified as scripting languages. they’re scripting languages, however most likely not within the sense that you just imagine. they’re scripting languages for these reasons:

They support a quick development cycle (edit-run-edit) by interpreters. No compilation is required.

They specialize in fast programming by requiring you to code less. as an example, you do not have to be compelled to take care of static forms of variables. Fewer declarations ar required in programs. as a result of these attributes, these languages may be used for everyday task one-liners. Imagine developing a alleged laugh (such as scanning the log files) in C, as an example.

A strong set of inherent libraries supports the handling of text and files.

Unfortunately, by the word scripting, many folks imagine poor languages that may be used just for tiny programs. That was true within the past and continues to be true for a few languages, like csh. After Perl, scripting languages ar languages that specialize in fast development, though Perl still has the smell of recent scripting attributes. even though you cannot appear to throw off this illusion, don’t decision R-uby a scripting language; instead, decision it a “dynamic object-oriented language.”

Unlike Perl, R-uby could be a real object-oriented language; OOP options don’t seem to be AN add-on. R-uby uses less punctuation ($,@,%, and so on), less context dependency, and fewer implicit sort conversion, thus R-uby programs tend to be less cryptic.

Ruby is AN open supply, understood , object-oriented artificial language created by Yukihiro Matsumoto, UN agency selected the gemstone’s name to counsel “a jewel of a language.” R-uby is meant to be easy, complete, extensible, and transportable . Developed totally on UNIX , Ru-by works across most platforms, like most UNIX system -based platforms, DOS , Windows , Macintosh , BeOS , and OS/2 , as an example. in step with proponents, R-uby’s easy syntax (partially galvanized by adenosine deaminase and engineer ), makes it decipherable by anyone UN agency is at home with any trendy artificial language.

R-uby is taken into account almost like Smalltalk and Perl . The authors of the book Programming R-uby: The Pragmatic Programmer’s Guide , David Thomas and saint Hunt say that it’s absolutely object-oriented, like Smalltalk, though a lot of standard to use, and as convenient as Perl, however absolutely object-oriented, that results in higher structured and easier-to-maintain programs. To be compliant with the principles of maximum programming (XP), R-uby permits parts of comes to be written in different languages if they’re higher suited.
