Comprehending Adts*
Comprehending ADTs* Martin Erwig School of EECS Oregon State University [email protected] Abstract We show how to generalize list comprehensions to work on abstract data types. First, we make comprehension notation automatically available for any data type that is specified as a constructor/destructor-pair (bialgebra). Second, we extend comprehensions to enable the use of dif- ferent types in one comprehension and to allow to map between different types. Third, we refine the translation of comprehensions to give a reasonable behavior even for types that do not obey the monad laws, which significantly extends the scope of comprehensions. Keywords: Functional Programming, Comprehension Syntax, Abstract Data Type, Generalized Fold, Monad 1 Introduction Set comprehensions are a well-known and appreciated notation from mathematics: an expression such as fE(x) j x 2 S; P(x)g denotes the set of values given by repeatedly evaluating the expression E for all x taken from the set S for which P(x) yields true. This notation has found its way into functional languages as list comprehensions [3, 17, 18]. Assuming that s denotes a list of numbers, the following Haskell expression computes squares of the odd numbers in s. [ x ∗ x j x s; odd x ] The main difference to the mathematical set comprehensions is the use of lists in the generator and as a result. In general, a comprehension consists of an expression defining the result values and of a list of qualifiers, which are either generators for supplying variable bindings or filters restricting these. Phil Wadler has shown that the comprehension syntax can be used not only for lists and sets, but more generally for arbitrary monads [19]. -

Chapter 1: Introduction to the Pencil Code Environment
Chapter 1: Introduction to the Pencil Code Environment In this manual we will show how to use Pencil Code to explore programming. Pencil Code is a free programming tool available at pencilcode.net. Pencil Code was developed by Google engineer David Bau together with his son Anthony Bau, with open-source contributions from many others. Two Ways of Looking at a Program There are two ways of viewing a program. A computer user sees a program by looking at its output. A programmer works with a program’s source code. In Pencil Code, the screen is split into two halves, with the source code on the left and the output on the right. You run programs by by pressing the “play” button in the middle. The Pencil Code interface splits the screen, showing source code on the left and output on the right. The play button in the center runs the code and produces output. Languages and Libraries in Pencil Code Pencil Code supports code in both blocks and text using mainstream web programming languages and useful libraries including: • HTML, the standard HyperText Markup Language for the web. • JavaScript, the standard programming language of web browsers. • CSS, the standard Cascading Style Sheet language for visual styles on the web. • jQuery, a popular library that simplifies programming interactive websites. • CoffeeScript, a language that lets you do more with less typing than JavaScript. • jQuery-turtle, which extends jQuery to simplify graphics and animation for novices. With Pencil Code, students can use these technologies to create web applications with global visibility and impact while exploring fundamental concepts in computational thinking. -

The Language Features and Architecture of B-Prolog 3
Theory and Practice of Logic Programming 1 The Language Features and Architecture of B-Prolog Neng-Fa Zhou Department of Computer and Information Science CUNY Brooklyn College & Graduate Center [email protected] submitted 5th October 2009; revised 1th March 2010; accepted 21st February 2011 Abstract B-Prolog is a high-performance implementation of the standard Prolog language with sev- eral extensions including matching clauses, action rules for event handling, finite-domain constraint solving, arrays and hash tables, declarative loop constructs, and tabling. The B-Prolog system is based on the TOAM architecture which differs from the WAM mainly in that (1) arguments are passed old-fashionedly through the stack, (2) only one frame is used for each predicate call, and (3) instructions are provided for encoding matching trees. The most recent architecture, called TOAM Jr., departs further from the WAM in that it employs no registers for arguments or temporary variables, and provides variable-size instructions for encoding predicate calls. This paper gives an overview of the language features and a detailed description of the TOAM Jr. architecture, including architectural support for action rules and tabling. KEYWORDS: Prolog, logic programming system 1 Introduction Prior to the first release of B-Prolog in 1994, several prototypes had been de- arXiv:1103.0812v1 [cs.PL] 4 Mar 2011 veloped that incorporated results from various experiments. The very first proto- type was based on the Warren Abstract Machine (WAM) (Warren 1983) as imple- mented in SB-Prolog (Debray 1988). In the original WAM, the decision on which clauses to apply to a call is made solely on the basis of the type and sometimes the main functor of the first argument of the call. -
Homework 5: Functional Programming and Haskell
Com S 541 — Programming Languages 1 December 5, 2002 Homework 5: Functional Programming and Haskell Due: problems 1(b),1(c), 2(b), and 4-8, Tuesday, December 3, 2002; remaining problems Tuesday, December 10, 2002 In this homework you will learn about the basics of Haskell, how Haskell can be considered as a domain-specific language for working with lists, basic techniques of recursive programming over various types of data, and abstracting from patterns, higher-order functions, currying, and infinite data. Many of the problems below exhibit polymorphism. Finally, the problems as a whole illustrate how functional languages work without statements (including assignment statements). Since the purpose of this homework is to ensure skills in functional programming, this is an individual homework. That is, for this homework, you are to do the work on your own, not in groups. For all Haskell programs, you must run your code with Haskell 98 (for example, using hugs). We suggest using the flags +t -u +98 when running hugs. A script that does this automatically is pro- vided in the course bin directory, i.e., in /home/course/cs541/public/bin/hugs, which is also avail- able from the course web site. If you get your own copy of Haskell (from http://www.haskell.org), you can adapt this script for your own use. You must also provide evidence that your program is correct (for example, test cases). Hand in a printout of your code and your testing, for questions that require code. Be sure to clearly label what problem each function solves with a comment.
