42. Envision: Scheme With Pictures An extension of the scheme programming language to support research in computer vision. http://www.cs.hmc.edu/~fleck/envision/envision.html

Envision: scheme with pictures Daniel E. Stevenson and Margaret M. Fleck This document describes an implementation which still being debugged. We hope for an alpha release in the near future. However, please don't expect the same quality control you might expect in a finished product. This document describes Envision, an extension of the Scheme programming language to support research in computer vision. It includes high-level discussion, a user reference manual, example code, and directions on how to obtain and install a copy of the language. A paper on Envision appeared in the 1997 Usenix Conference on Domain-Specific Languages ( postscript ), pp. 271-284. What is Envision? Computer vision algorithms are notoriously difficult to implement, read, maintain, adapt, and share. This slows the progress of research in computer vision and discourages other computer scientists from using techniques developed in computer vision. We have developed a solution to this problem, where previous researchers have failed , by combining insights from computer vision and programming language design. Envision improves computer vision programming in two ways.

43. LEHALLE.net - Portal To Lehalle Family A version of AWK in the scheme programming language. It goal is to offer the same features as awk to scheme programmers. http://charles.lehalle.free.fr/tools.html

MEMBERS SUBJECTS Tools scawk Home page of Scawk Scawk is a port of awk to scheme. The implementation of scheme used is siod, but it is planned to extend scawk to other scheme implementations. The interressant point with siod is that a scheme file can be compiled into an executable one. So I use scawk as an exec file for WinNT (scawk.exe). I tied to give to scawk all the features of awk. It is not completed actually, but I think scawk has enough functions to be used. Actually I use scawk instead of awk for a very large number of applications. The point is that I have not actually a CWEB-like application to use with scawk, but I work on it. The use of awkweb is the only point that makes me prefer awk to scawk sometimes. You can download the full version 1.0 of scawk here (including binaries for WinNT). You can read the documentation (pdf format) here Links : awk FAQ siod scheme Here is an example of scawk file : ; contants : (define *example* 0) (define *classic* 1) (define *paragra* 2) (define *section* 3) (define *nothing* 4) (define section-s '( )) (define paragra-s '( )) (define example-s '( )) (define replace-strings '( ( ))) (define *nbsp* ; I cut this line for HTML pretty printing reasons : (define head-and-foot '( ; global variables : (define current-type *nothing*) (define special-end #f) (define (*begin* ) (display (car head-and-foot)) ) (define (*end* ) ; do not forget to close current env type : ; and write the foot (display (cadr head-and-foot)) )

IU Programming Languages Research Current programming language research at IU explores a variety of semantic and pragmatic issues and their relation to other areas of theory and application. The work of Kent Dybvig, Dan Friedman, Amr Sabry, and Chris Haynes focuses on functional, object-oriented, dynamic, and symbolic programming mechanisms, often expressed via extensions and derivatives of the Scheme programming language. This work often involves formal methods of static program analysis, such as partial evaluation, abstract interpretation, and type systems. Through such methods, and imaginative engineering, one hopes to combine expressive abstraction mechanisms and efficient execution. A number of faculty have interests that tie programming language research with other areas of research. Dennis Gannon explores aspects of programming language design related to parallel and scientific computation. Steve Johnson uses transformation techniques developed for programming languages in the formal derivation of hardware systems Daniel Leivant has worked on logics of programs, and on applicative programming languages that capture computational complexity classes.

< low x high) ((low ... ) The semantics of LET is to evaluate the expressions in an environment extended by the names which have initial values obtained by evaluating the expressions . An example is: (let ( (a 1) (b 2) ) (+ a b) ), which binds the value 1 to a, 2 to b and then evaluates the expression (+ a b). LET is syntactic sugar for lambda binding: ( (lambda ( ...) ; before ; rewrites to ((lambda ( ) ((or ...) ;=> (let ( (temp ) ) (if temp temp (or ...)) ) ) ) ) Form: (and ) ((and ...) ;=> (if (and ...) #f) )) ) ) Forms: (let ( ( ...) (let < n 2) accum (loop (- count 1) (* count accum)) Semantics: LET evaluates the s in the enclosing environment in some unspecified order and then extends the environment by binding the values to the s and evaluates the expressions from left to right, returning the value of the last expression as the value of the LET. LET can be thought of as a "parallel assignment". Note that the value of B in the first example depends on the value of A in the outer environment. The second form is known as NAMED LET and allows recursion within the let form. For the example above, the call to LOOP acts as a goto which rebinds the ...) ;=> ((lambda (

Office: FEC 349C Description I'd rather write programs to write programs than write programs. -D. Sites What I cannot create I do not understand. - R. Feynman After a quick review of the basic features of the Scheme programming language, we will explore advanced language features not normally covered in CS 257. These include macros, lazy evaluation, streams, continuation passing style, and call/cc. We'll also look at the lambda calculus and the Y-combinator. The bulk of the course will focus on implementation of Scheme interpreters and compilers. Topics will include scanning, parsing, evaluation, macro-expansion, compilation, and garbage collection. Each student will write a working Scheme interpreter or compiler in a non-garbage-collected language (e.g., C). Undergraduates who have taken CS 257, and who want to learn more about Scheme and its implementation are welcome to take CS 491. Graduate students who have taken CS 257 (or have equivalent proficiency in Scheme) are welcome to take CS 591. Textbooks The text for the course will be Scheme and the Art of Programming by George Springer and Daniel P. Friedman (MIT Press, 1989).

Xml Matters #31: Sxml And Ssax Manipulating XML in the Scheme Programming Language David Mertz, Ph.D. Parenthesizer, Gnosis Software, Inc. October 2003 Previous installments have looked at XML libraries for various programming languages, and with various strengths and weaknesses. The Lisp family of languages remains popular, especially in teaching and among purists. The SSAX library for Scheme is an efficient pure-functional parser; SXML is a tree library (like DOM); and related tools SXSLT and SXPath have been created to work with these. This installment looks at the advantages of parsing in a strongly functional language, and compares SSAX with libraries for other languages. Introduction I am awareas a factual matterthat there are connoisseurs of single-malt scotches. But given that I rarely drink alcohol at all; and when I do it in less concentrated amounts as beer or wine, I have trouble fully understanding the mindset or discourse of these connoisseurs. I feel almost the same way about Lisp and Scheme programming. I can tell that it is an area filled with sophistication and intelligence, but somehow both the Polish (prefix) notation and endless parentheses, and the fervent semantic eshewal of a distinction between code and data, continue to feel alien to me. Nonetheless, I have enough of a fascination that I want to see how these languages approach XML processing.

As it happens, a document of this type exists: The Scheme programming language, by Ken Dickey, ftp://ftp.cs.indiana.edu/pub/scheme-repository/doc/pubs/intro.txt Interestingly enough, the author states: "Scheme is a small, exceptionally clean language which is, very importantly, fun to use." This is in contrast to many descriptions of DSSSL, which frequently seem to start out by saying "DSSSL style sheets are based on Scheme, this dialect of Lisp, and you're really going to be confused ..."

Other Scheme Books Schemers Inc. is pleased to announce the availability of the following Scheme-related texts: "The Little Schemer" "The Seasoned Schemer" "Structure and Interpretation of Computer Programs", 2nd edition "Essentials of Programming Languages", 1st edition ... Other books "The Little Schemer" [Fourth Edition] by Daniel P. Friedman and Matthias Felleisen Drawings by Duane Bibby Foreword by Gerald J. Sussman Schemers Recommendation "The Little Schemer" and "The Seasoned Schemer" would prove popular as companion texts for any complete introductory course in Computer Science. The notion that thinking about computing is one of the most exciting things the human mind can do sets both "The Little Schemer" (formerly known as "The Little LISPer") and its new companion volume, "The Seasoned Schemer", apart from other books on LISP and its dialects. The author's enthusiasm for their subject is compelling as they present abstract concepts in a humorous and easy-to-grasp fashion. Together, these books will open new doors of thought to anyone who wants to find out what computing is really about. "The Little Schemer" introduces computing as an extension of arithmetic and algebrathings that everyone studies in grade school and high school. It introduces programs as recursive functions and briefly discusses the limits of what computers can do. The authors use the programming language Scheme and a menu of interesting foods to illustrate these abstract ideas. "The Seasoned Schemer" introduces the reader to additional dimensions of computing: functions as values, change of state, and exceptional cases.
