Salt commands are executed using a common structure: salt '*' pkg.install vim [target] [module.function] [arguments] The target determines which systems apply the command. In the example above we target all ('*') the Salt minions. See the targeting minions documentation for more...

The following is a full example of using XHTML with JavaScript served by PHP as a single-file. <?php if (isset($_SERVER['HTTP_ACCEPT']) && stristr($_SERVER['HTTP_ACCEPT'],'application/xhtml+xml')) { // Client header isset` and explicitly declares XHTML parser support. header('Conte...

HTML5 defines some HTML attributes as boolean; a boolean can only be true or false. The specification simply states that the presence of a boolean attribute implies that the attribute is set to true. In example using a disabled attribute in the following example disables the button input element: &...

Using XHTML you should avoid methods such as document.write and innerHTML as they treat XML as text and do not properly serialize code; an id attribute in HTML is essentially dumped in to the DOM and the id attribute is not serialized which means when trying to reference to it with something such as...

This example shows a simple global definition of a complexType. The definition is considered global as it is a child of the xs:schema. Globally defined types can be used elsewhere in the schema. This is the most common form for declaring a global xs:complexType, it defines the child elements using ...

In this example we are creating a new xs:complexType (EmployeeType) based on an existing xs:complexType (PersonType). The construction of this is slightly more complicated. Because the base xs:complexType (PersonType) is considered to be complex (more about this below) we add the <xs:complexCon...

This is where things get a little tricky. We are now restricting an existing xs:complexType. Our SolidStateDriveType derives from HardDiskType but removes the spinUpTime attribute and the RotationSpeed element. Notice the approach for dealing with attributes and elements is different. To remove an ...

int highScore = 57; NSString *scoreBoard = [NSString stringWithFormat:@"HighScore: %i", (int)highScore]; NSLog(scoreBoard);//logs "HighScore: 57"

Let's combine all of the examples above into one complex scenario: using libc's lfind function. For more details about the function, read the man page. I urge you to read it before going on. First, we'll define the proper prototypes: >>> compar_proto = CFUNCTYPE(c_int, POINTER(c_int), PO...

Shows a very basic schema. Note: by convention elementFormDefault is set to 'qualified', in the really world you will be hard pressed to find a schema that does not set this (so just include it in your schemas!). <?xml version="1.0" encoding="utf-8" ?> <!--Created wit...

By convention elementFormDefault is always set to qualified, but lets look at what it actually does. First with elementFormDefault set to qualified. <?xml version="1.0" encoding="utf-8" ?> <!--Created with Liquid Studio 2017 (https://www.liquid-technologies.com)--&g...

One of the simpler ways of implementing an authorization system is using the flask-login extension. The project's website contains a detailed and well-written quickstart, a shorter version of which is available in this example. General idea The extension exposes a set of functions used for: log...

Any declaration (variable, const, function, class, etc.) can be exported from module to be imported in other module. Typescript offer two export types: named and default. Named export // adams.ts export function hello(name: string){ console.log(`Hello ${name}!`); } export const answerToLi...

This used the flex layout with the sortable to create a grid of responsive boxes that can be moved around by dragging and dropping. HTML <div id="sortable"> <div>1</div> <div>2</div> <div>3</div> <div>4</div> <div&gt...
