Conventions used

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: “Create a file named Announcement.php in the newly created directory so that we can define the Announcement class for our entity type.”

A block of code is set as follows:

{% for tag in node.getTags %}
  <div>Tag: {{ tag.label }}</div>
{% endfor %}

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

mkdir -p src/Entity

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 will see the generated permissions on the Permissions form.”
