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…

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…

We had to cover monads eventually, and there are many great monad tutorials out there (see, for example, here: http://www.haskell.org/haskellwiki/Tutorials#Using_monads). In fact, there are web resources concerned solely with organizing the many monad tutorials available in the wild, and developing…

I caught up with Simon Peyton-Jones, author of the Glasgow Haskell Compiler (GHC) and a key contributor to the Haskell functional programming language, at YOW! 2011. Simon is a pure functional guy. That said, he's OK with side effects as long as you can control them (so,…

Ever wonder what would happen if you happened upon Simon Peyton-Jones, author of the Glasgow Haskell Compiler (GHC) and a key contributor to the Haskell functional programming language, and John Hughes, fellow Haskellite, computer scientist, creator of QuickCheck, and author of…

Continuing with the series of conversations filmed in the "social room" at Lang.NEXT 2012, we present Andrei Alexandrescu, Walter Bright, Erik Meijer, and Andrew Adams-Moran discussing/debating various programming topics including pure versus native languages, Haskell, D, and more.…

"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…

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…

Matthew Podwysocki is a senior consultant for Microsoft platform technologies in the D.C. area. He's been programming since he was a child and has a particular interest and passion for functional programming. Functional programming is all the rage these days. General purpose imperative…

It's been far too long since we've had some meaty functional programming content on C9. Luckily, none other than Graham Hutton dropped off a present on our doorstep! Dr. Hutton graciously provided Channel 9 with his latest self-filmed lecture—thank you, Graham! We're honored. This is certainly…
