Conventions used

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

Code in text: 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: “For instance, to test whether a textbox can handle inputs including spaces, we may use the string one two.”

A block of code is set as follows:

create_user(permission)
{
     user = create_user()
     if(permission == ADMIN)
     {
           make_admin(user)
     }
     return user
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “That limit should be apparent before users try to use it – the Add user button should be grayed out with a note saying why, for instance, instead of letting users click the button.”
