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: "A thousand-line function with multiple nested if and while loops (and I've seen plenty) is pretty much untestable." A block of code is set as follows:
public static class MyMath
{
public static int Add(int a, int b)
{
return a + b;
}
}
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
<!DOCTYPE html>
<html>
<head>
[...]
</head>
<body ng-app="shopApp">
<%- include navbar.ejs %>
<div class="container" ng-controller="productController">
[...]
</div>
</body>
</html>
Any command-line input or output is written as follows:
sudo apt-get update
sudo apt-get install ubuntu-desktop
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: "Git will rewind your work until it finds the master, which is after the Added weapons commit."
