Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Let's use String.Chars as an example, where we'll call the h helper on String.Chars to learn more about the module from its documentation."

A block of code is set as follows:

person = %{ name: "Brandon" }
person = %{ name: "Richey" }

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

iex(1)> greeting = "Hello There"
"Hello There"

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
