Conventions

In this book, you will find a number of styles of text 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: "Add a struct to test.d, which uses alias this to activate subtyping."

A block of code is set as follows:

import project.foo;; // disambiguate with project.foo
import bar; // you can disambiguate calls with the name bar

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

coffimplib myfile.lib

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Running the program will print Hello, world! in green text on a red background."
