Detailed explanation of the iterator IN Ruby and the Ruby Generator D guago recently wanted to build a website. In addition, he had long had the idea of learning a dynamic language. Among the programming languages that meet two conditions, Ruby and Python are the most appropriate. Now Ruby on Rails is booming! Therefor

Understand Ruby scopes and Ruby scopes What is scope? When talking about the scope, you should immediately thinkVariableAndVisibilityThese two words,VariableAndVisibilityIt is the main content of the scope. Yes, the scope is about where the code variables are visible. After you fully understand the scope, I will give you a piece of code, you can easily know what variables are visible at this time, and most

The concept of class objects in Ruby and the concept of ruby objects Object-oriented Programs involve classes and objects. A class is a blueprint created from an individual object. In object-oriented terms, we say that James's bicycle is an object instance called a bicycle. Example of any vehicle. It includes wheel, horsepower, fuel or gas tank capacity. Data members of vehicles with these features. These f

Ruby implements two mail sending methods, and ruby implements mail sending. In fact, as long as you are willful, you can use telnet to send emails. However, this cat is not so capricious. We should use the KISS Principle to send emails. This blog post only describes how to send emails, but does not involve email receiving. If you have the opportunity to open a separate blog post in the future.

Most Ruby programs, their design, logic, and action, are all centered around objects. The main task of writing a Ruby program is to create objects and then give them the ability to perform actions. Ruby is an OOP language, an object-oriented language in which you perform calculations, data processing, input, and output by creating objects and then letting the ob

String processing in ruby is flexible. "ABC" [0] returns 97 as"ABC" [1] 98"ABC" [2] 99"ABC" [3] Nil"ABC" [-1] 99 forward number"ABC" [-2] 98"ABC" [-3] 97"ABC" [-4] Nil "ABC" * 2 returns "abcabc" supporting Multiplication "ABC" + "def" returns "abcdef" "Abcdef" [] "A" extracts one digit from the position 0"Abcdef" [1, 3] "BCD""Abcdef" [-3, 3] "def""Abcdef" [1 .. 3] "BC" from 1 to 3 Come to a riddleProgram Code highlighting produced by Acti

Arrays in ruby are created by square brackets. The initial values can be placed in square brackets and separated by commas. array elements can be of different types and support addition and multiplication. Ary = [1, 2, "3"]Ary * 2 Returns [1, 2, "3", 1, 2, "3"]Ary + ["Lee", "ho"] returns [1, 2, "3", "Lee", "ho"]Ary [] returns [1, 2] and obtains two elements starting from position 0.Ary [0 .. 2] returns [1, 2, "3"] From position 0 to position 2 Arr

inheritance of loading modules and classes: Module MdefPuts "' The ' method ' in module M"EndEnd Class CInclude MEnd Class D End obj = d.newObj.reportThe example method is defined in module M, the C class is mixed with module M, Class D is a subclass of Class C, and obj is an instance of Class D, the object of obj can call the method. From an object's perspective, suppose you are an object, someone sends you a message, you have to find a way to respond, and the idea is probably like this:

About Ruby on Rails Ruby on Rails is an application stack that provides developers with a framework to quickly create a variety of Web applications. ruby on Rails does take a little while to install on a virtual server, but luckily there are a lot of helpful tools to make this process as easy as possible. you can run this tutorial on your droplet as a user with S

Example parsing: Implementation of observer mode in Ruby design mode development, and ruby Design Mode In general, the observer mode should be defined as follows: building a clean interface between the source of news that some object has changed and the consumers of that news. The observer mode establishes a clean interface between the producer and consumer of the message, so that the coupling between the p

Ruby is a powerful object-oriented scripting language that allows you to quickly and easily object-oriented programming. Sometimes it's a little "fuss" to develop small projects using formal object-oriented languages such as Smalltalk, Eiffel, or C + +. And Ruby just meets the needs of these object-oriented programming. Of course, you can also use Ruby for genera

Python and Ruby are both excellent languages, all of which emphasize people-oriented and have their own merits. However, I feel Ruby seems more friendly. Ruby draws on the advantages of smalltalk, Python, and Perl. We recommend that you learn Ruby resources: English Clear and short free ebook, I think it is

When learning a new programming language, we must be clear about a few questions:What is the type model of the language?Strongly typed / weakly typed, static type / dynamic typeThe type model changes the way the problem is handled and controls how the language runsWhat is the programming paradigm of language?Object-oriented, functional, procedural, etc.How to interact with the language?Compiling, interpretingWhat is the judgment structure of language (decision construct) and the core data struct

Ruby's installation can go to Ruby's official web site to download the Ruby1.56 Windows Installer package, install the after installation, open the DOS window, input ruby-v display Ruby 1.8.6 (2007-03-13 patchlevel 0) [I386-mswin32] shows that Ruby has been installed successfully and the version number is Ruby 1.96.

Explain the methods in Ruby and the Ruby Methods The Ruby method is very similar to the functions in other programming languages. The Ruby method is used to bind one or more repeated statements in a unit. The method name should start with a lowercase letter. If the name of a method starts with an uppercase letter,

Analysis of Ruby relay and message-related knowledge, analysis of ruby Inheritance allows you to create a class as the refinement and specialization of another class ). For example, in our automatic karaoke system, the concept of "Song" is encapsulated in the Song category. Then, as the market grows, we need to provide karaoke support. A karaoke song is no different from other songs (it just does not have a
