C9 Lectures: Dr. Ralf Lämmel  Advanced Functional Programming  Evolution of an Interpreter
Avg Rating: 5
(6)In part 3 of the Advanced Functional Programming lecture series, Dr. Lämmel focuses on the domain of language interpretation as a method of understanding some important functional programming techniques. As a side effect, some basics of programming language theory are also informally presented.… 
C9 Lectures: Dr. Ralf Lämmel  Advanced Functional Programming  The Expression Problem
Avg Rating: 4
(10)"The Expression Problem is a new name for an old problem. The goal is to define a datatype by cases, where one can add new cases to the datatype and new functions over the datatype, without recompiling existing code, and while retaining static type safety (e.g., no casts)."  Philip…

(13)Well, my friends, the day has arrived. For thirteen weeks, you have been provided all the conceptual tools to take the leap into the deep end of the functional programming pool and float safely. The great Dr. Erik Meijer has generously given his value time to teach us the fundamentals as delivered…

(13)In Chapter 12, Lazy Evaluation, Dr. Meijer takes us on a journey into the world of order of evaluation (when expressions are evaluated). In the case of lazy evaluation, computation is delayed until the result of the computation is known to be required. Most programming languages that most of you use…

(11)Yes. You read the title correctly! For today's lecture in the Functional Programming Fundamentals series of lectures the great Dr. Graham Hutton, author of the Programming in Haskell book that Dr. Erik Meijer has based this lecture series on, is guest lecturing Chapter 11  The Countdown Problem!…

(12)In Chapter 10, Declaring Types and Classes, Dr. Meijer teaches us about type declarations, data declarations, arithmetic expressions, etc. In Haskell, a new name for an existing type can be defined using atype declaration:type String = [Char]String is a synonym for the type [Char].Like function…

(11)In Chapter 9, Interactive Programs, Dr. Meijer will teach us how to make programs in Haskell that are sideeffecting:interactive. Haskell programs are pure mathematical functions with no side effects. That said, you want to be able to write Haskell programs that can read input from the keyboard and…

(11)In Chapter 8, Functional Parsers, it's all about parsing and parsers. A parser is a program that analyses a piece of text to determine its syntactic structure. In a functional language such as Haskell, parsers can naturallybe viewed as functions. type Parser = String > TreeA parser is a…

(15)In Chapter 7, Dr. Meijer teaches us about HigherOrder Functions. A function is called higherorder if it takes a function as an argument and returns a function as a result:twice :: (a > a) > a > atwice f x = f (f x)The function twice above is higher order because it takes a function…

(15)In Chapter 6, Dr. Meijer guides us through the world of recursive functions. In Haskell, functions can be defined in terms of themselves. Such functions are called recursive. For example: factorial 0 = 1factorial (n+1) = (n+1) * factorial nfactorial maps 0 to 1, and any other positive…
