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: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

    // assert
    let dbCustomer = CustomerRepository.get customerID
    dbCustomer |> should equal newCustomer

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

let div x y =
  // precondition 
  assert(y > 0)
  assert(x > y)

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

> parse "MMXIV";;

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: "In order to get the path to the library you want to reference, right click on References in the Solution Explorer."

Note

Warnings or important notes appear in a box like this.
