But recently want to re-execute the TK code, found in require ' TK ' when the error bird! The ruby2.1.3 version is now in use.

Open Class and Monkey patchesin Ruby, a class defines a method that does not differ from any other statement, and is executed on a line. The following example: Class Example def method_1 puts ' method 1 ' end class Example def method_2 puts ' Method 2 ' End end In this case, when the class example is first defined, there is not a class called example, so Ruby starts to define

There are many popular frameworks for online Web application development at the moment. There are also many different types of frameworks, such as those with a large number of plug-ins that can make you faster iterations (such as Rails), or other very simple and low-level (like flask).Two relatively more popular frameworks in Web application development are Ruby on Rails and Laravel. All two of them are very mature projects that have been available fo

Ruby is an open source dynamic programming language that has beautiful syntax for building scalable Web applications. Ruby Gems can be a good way to improve the development efficiency of ruby developers. There are several ways to install Ruby on an Ubuntu system, and each method takes only a few steps to get it done.

Ruby methods are very similar to functions in other programming languages, and Ruby methods are used to bundle one or more duplicate statements in one cell. The method name should start with a lowercase letter. If the name of a method starts with an uppercase letter, Ruby might think that this is a constant, so the call can be parsed correctly. Method should de

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

Any method defined by a class in Ruby can accept a process object (Proc) as an additional parameter, in a method, you only need to use the yield expression to call this process object. During the call, the parameter of the object is specified by the yield expression, and its return value is returned as the value of the yield expression. The following is an example in the ruby document. Def threetimes The

Blank characters include space characters, tabs, and line breaks. They are not tags, but are used to separate different tags, so that they are not merged into a tag. Note:Sometimes blank characters are required, and some are actually forbidden. 1. linefeed used as the statement TerminatorEach statement in C and Java must end with a semicolon. In Ruby, you can use semicolons to terminate the statement, but this is not necessary. Only when you tryCo

Some important differences between Ruby and C # are as follows: 1. Ruby is a dynamic language, and C # Is a static language-that is, after an object is new, Ruby can dynamically add some attributes or methods to the object instance (as does JavaScript) 2. ruby deliberately weakens the concept of variable types.
