Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Your own bundles are usually stored within the src/ directory, while the third-party bundles sit within the vendor/ directory."

A block of code is set as follows:

public function indexAction()
    {
        return $this->render('default/index.html.twig');
    }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

use AppBundle\Entity\Task;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;

Any command-line input or output is written as follows:

$ curl -sS https://getcomposer.org/installer | php
$ sudo mv composer.phar /usr/local/bin/composer

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "You should see a Hello anonymous! welcome text."
