The F# object-oriented constructs are designed largely for use in APIs for software components. Two useful mechanisms in APIs are to permit callers to name arguments and to let API designers make certain arguments optional. Named arguments are simple. For example, in Listing 6-2 the implementations of some methods specify arguments by name, as in the expression Vector2D(dx=dx+x, dy=dy). You can use named arguments with all dot-notation method calls. Code written using named arguments is often much more readable and maintainable than code relying on argument position. We will frequently use named arguments throughout the rest of this book. A member argument is declared optional by prefixing the argument name with . Within a function implementation, an optional argument always has an option<_> type; for example, an optional argument of type int will appear as a value of type option<int> within the function body. The value will be None if no argument is supplied by the caller and Some(arg) if the argument arg is given by the caller. For example: open System.Drawing type LabelInfo( text:string, font:Font) = let text = defaultArg text "" let font = match font with | None -> new Font(FontFamily.GenericSansSerif,12.0f) | Some v -> v member x.Text = text member x.Font = font The inferred signature for this type shows how the optional arguments have become named arguments accepting option values: type LabelInfo = new : text:string option * font:System.Drawing.Font option -> LabelInfo member Font : System.Drawing.Font member Text : string You can now create LabelInfo values using several different techniques:

Asking designers to write code, or programmers to get involved in the aesthetics of an application, is often a bad idea Even if you re providing both roles, it can be helpful to separate them, in order to focus on one at a time We showed in our overview of server MVC how code and presentation could become intertwined, and we separated them out using a template system What are the options available to us here on the browser In chapter 3, we demonstrated how to structure our web pages so that the CSS, HTML, and JavaScript are defined in separate files In terms of the page itself, this split follows MVC, with the stylesheet being the View and the HTML/DOM being the model (a Document Object Model).

Tip We recommend that you use four-space indentation for F# code. Tab characters cannot be used in

Writing all our JavaScript in a separate file is a good start for enforcing separation of the View, but even with this in place, we can entangle the View with the logic roles (that is, Model and Controller) without having to try too hard. If we write JavaScript event handlers inline, such as

then we are hard-coding business logic into the View. What is datafeed3 What does the value of mytextbox have to do with it Why does importData() take two arguments, and what do they mean The designer shouldn t need to know these things. importData() is a business logic function. The View and the Model shouldn t talk to one another directly, according to the MVC canon, so one solution is to separate them out with an extra layer of indirection. If we rewrite our DIV tag as

The first real line of the program in Listing 2-1 is not code but a comment: /// Analyze a string for duplicate words Comments are either lines starting with // or blocks enclosed by (* and *). Comment lines beginning with three slashes (///) are XMLDoc comments and can, if necessary, include extra XML tags and markup. The comments from a program can be collected into a single .xml file and processed with additional tools or can be converted immediately to HTML by the F# command-line compiler (fsc.exe). We cover using the F# command-line compiler in more detail in 7.
