3. Dr. Philip Cannata 3 Textbooks (Required): Programming Languages: Application and Interpretation by Shriram Krishnamurthi - Free online book http://www.cs.brown.edu/~sk/Publications/Books/ProgLangs http://www.cs.brown.edu/~sk/Publications/Books/ProgLangs Textbooks (Recommended): "Generating Parsers with JavaCC, Second Edition" by Tom Copeland, Published by Centennial Books, Alexandria, VA. ISBN 0-9762214-3-8.Tom Copeland "The Definitive Antlr Reference: Building Domain-Specific Languages" Terence Parr (Author) (Pragmatic Programmers) (Paperback) Grading Grades will be calculated on the following scale: A: 90-100; B: 80-89; C: 70--79; D: 60-69; F: 0-59. Your final grade will be calculated by averaging your performance on Homework, Project(s), Quizzes and Exams with the following weighting: Homework 20%, Quizzes 15%, Project 15%, Exams 25% each. The lowest Quiz and Homework grades will be dropped before calculating a final grade. Quizzes There will be in class quizzes on a very regular basis. These quizzes will be based on day's course lecture material, readings from the course texts, and/or homework. Missed quizzes will be given a grade of zero unless there are extenuating circumstances (see below). Homework Homework exercises will be assigned with an explicit due date. Homework is to be done individually. Late homework will be given a grade of zero unless there are extenuating circumstances (see below). Examinations There will be two closed book exams, a Mid-Term and a Final. These exams must be taken on the specified date and at the specified time. If you miss an exam due to extenuating circumstances (see below), a grade will be negotiated for the exam based on a percentage of your homework, quizzes and other exam scores. Missed exams will be given a grade of zero. Extenuating Circumstances If you have difficulty meeting the requirements of this course, fail to hand in an assignment, or miss an exam because of extenuating circumstances, please advise your instructor in writing (not email) at the earliest possible date so that your situation can be discussed. If you encounter an unexpected medical or family emergency or a random act of Nature that causes you to miss the due date for homework or miss a quiz or exam, you must present suitable documentation in writing (not email) to the instructor before special consideration will be given. A file of all written correspondence will be kept by the instructor and decisions regarding them will be made at the end of the semester. Administration and Policies

12. Dr. Philip Cannata 12 Installing javacc on Windows http://java.net/projects/javacc/

13. Dr. Philip Cannata 13 Installing javacc on Windows Download javacc from http://java.net/projects/javacc/ I put the zip file in C:\Program Files\Java and extracted it to there. So, javacc is in C:\Program Files\Java\javacc-5.0\javacc-5.0\bin Change your path environment variable to include C:\Program Files\Java\javacc-5.0\javacc-5.0\bin or whatever your path is. Do the following to do this: path environment variables are in the System Properties -> Advanced Tab -> Environment Variables? Add the javacc path to the front of the existing “path” environment variable followed by a semi- colon? Edit the javacc program as follows: #!/bin/sh JAR="`dirname "$0"`/lib/javacc.jar" case "`uname`" in CYGWIN*) JAR="`cygpath --windows -- "$JAR"`" ;; esac java -classpath "$JAR" javacc "$@" Put double quotes around $0

14. Dr. Philip Cannata 14 javacc on the CS machines Greetings, We've installed javacc, the java compiler compiler. This is a parser generator for java. See https://javacc.dev.java.net/ for details.https://javacc.dev.java.net/ This will be made available on all departmental machines after our nightly cron job runs this evening. Javacc will be in the default $PATH, so you can access it simply by running 'javacc' from a terminal. However, if you need to use the javacc.jar file, you will need to add its location to your $CLASSPATH environmental variable. I have created a set of shell scripts to ease this process. If you use bash, run the following: source /lusr/share/lib/java/javacc/env.d/append.sh If you run csh or tcsh, run this instead: source /lusr/share/lib/java/javacc/env.d/append.csh Please send mail to gripe if you have any questions. -jason
