First I'll compare how design patterns are applied in object-oriented programming
and how you can use them in the functional realm. As you'll see, the gap is not so
wide, and many of the concepts translate into functional equivalents but with a
different implementation. I've introduced many different tools for Haskell
programming throughout the book: test frameworks, profiling tools, and so on. In
this chapter you'll see a summary of all of them and get some suggestions
concerning other ...

A major aspect of this is the reinterpretation of the original Gang of Four design patterns in terms of Scala and its language structures (that is the use of Traits, Classes, Objects and Functions).

We argue that comonads, the dual of monads, similarly provide a useful design
pattern, capturing notions of context dependence. However, comonads remain
relatively under-used compared to monads—due to a lack of knowledge of the
design pattern along with the lack of accompanying simplifying syntax. We
propose a lightweight syntax for comonads in Haskell, analogous to the do-
notation for monads, and provide examples of its use. Via our notation, we also
provide a tutorial ...

Combining these results in order to extend Haskell with a more natural support
for typecase programming is something we would like to try in the future.
Problems that use multiple instances of the design pattern are not composable.
For instance, in a generic programming context, we could have a class Generic
that allowed us to define generic functions with one type parameter; and we
could also have a class FMap for working with tries. Although, those classes are
structured in a ...

Now, let's consider the background and design of iterators and match this
illustration to the pattern itself. Design. The concept of iterators and enumerators (
also called generators) has been around for a long time. Enumerators are
responsible for producing the next element in a sequence defined by certain
criteria. Such a sequence is said to be ... The inspiration for this new way of
thinking comes from the database world (SQL) as well as the functional world (
Haskell and Mondrian).

We have implemented our scheme specifically for instance generators in Haskell,
but the same scheme could be applied to other computer languages and other
situations. One possible target would be F#, where there are interfaces instead of
type classes.Another target could be anobject-orientated language, where
design patterns [5] are popular. Computers are ideally suited to applying a
relationship using new parameters, but specifying these relationships can be
complex and ...

For the upcoming sample code that illustrates the strategic design patterns, we
precompiled a set of datatypes representing the abstract syntax of Haskell 98.
The resulting Term instances allow us to construct strategies that traverse over
Haskell parse trees. Thus, functional strategic programming with Strafunski
proceeds along the following steps: 1 . Apply the precompiler to the system of
datatypes that represent the terms on which to operate. 2. Import the precompiled
datatypes and ...
