COP5555: Programming Language Principles
Announcements
1/2 Final exam grades are available on E-learning. The "homework" score was obtained by dropping your lowest homework grade and weighting HW7 3 times. The "overall" score was .25*midterm + .4*final + .4*homework. (Recall that the midterm had max 80). The final grade was determined by the overall score with the following cutoffs: 85 A, 80 B+, 70 B, 60 C+, 40 C. (All HW rescore requests were looked at--in most cases, a rescore could not affect the assigned grade.)
12/12 E-learning update. Homework solutions folder added
12/11 HW7 HW7
graded. Make sure all grades are correct, and if any inconsistency, please send me email.12/10 Pico+ Gallery: If you have a really cool Pico+ program you'd like to share send it to me and I'll add to our gallery. No prizes, just fame and glory and the admiration of your peers. Anonymous submissions are OK, too. but you won't get the fame and glory.
12/10 E-learning update: If one of your first homework submissions received a low score because one mistake resulted in failing many test cases, thus causing your resubmission to also receive a low score, you may submit a rescore request via E-learning (look in the homework folder). You need to clearly explain what happened so that it can be verified by looking at your two submissions.
12/10 Final exam logistics
 | You will be allowed four pages of notes, otherwise the exam is closed book. |
| The exam will start promptly at 7:30am on December 17, so come a few minutes early to ensure that you have the full time. |
| Bring a photo ID--I'll check this during the exam. |
| Edge students: your exams are usually faxed--please use a pen or dark pencil. The exam will be emailed to your proctor after the in-class students have taken it. You have one week to take the exam and return it to me. |
12/10 E-learning update: slides on Code improvement and Scripting languages have been uploaded. Course evaluations will be done in class on 12/10.
12/8 TA's Monday office hour is moved from 3:00pm to 1:00pm for this week(12/8) & next week(12/15).
12/3 E-learning update: HW6 &
HW5 reregrading finalized. 12/3 The final exam will be given at the date and time
scheduled by the registrar for our course, 7:30am-9:30am
on Dec 17. It will
cover material from the entire semester.
12/3 E-learning
update: Slides on Logic Programming, HW7.
12/3
HW7 is a resubmission of HW6 which will be tested with the same test
cases. The grade is 0 or 100 and will count as three homework
grades. Plagiarism detection software will be employed as will
measures to detect other kinds of cheating (such as hard coding
solutions for specific test cases) If your HW6 already passed
all the test cases, you do not need to resubmit.
12/1 E-learning update: HW6 TEST.tar is distributed through HW6 submission. 11/26 One more-- delete the extra GOTO in assignment
statements of type image_int. i.e.
11/26 Typo in HW6. Several places in the
spec of BinOpExpression: For (Expression1.type =
AAA or Expression1.type =BBB) and
(Expression2.type = CCC or 11/24 E-learning update: Midterm solutions and slides
on procedures and OOP have been posted.
11/23 E-learning update: HW5 graded & HW4 regraded.(HW4:AVG 83.7, MED 96)
11/17 E-learning updates: HW6 and slides on
control flow have been posted. You will not need to explicitly
resubmit HW5. We will rerun the HW5 solutions on your HW6
submission instead. 11/15 A HW5 Submission HELP has been added. 11/10 Code Generation FAQ 11/7 Midterms for on-campus students will be handed
back in class today. If you don't make it to class, you may pick
yours up during class next week or during my office hours.
Solutions will be posted after all of the EDGE exams have been
received and graded. Discussions with me about your exam grade
(except for obvious errors like adding the score incorrectly) should wait
until after you have looked at the solutions. 11/3 E-learning updates: HW5 and slides on
axiomatic semantics have been posted.. Some example Pico
programs and the resulting class files are in the HW5/Examples
folder. SimpleImageDemo.java was moved to the HW5 folder. 10/31 Edge students: Please remind your proctor that
when faxing your exam, they should include a cover sheet with my name
on it (the fax machine is shared with other members of the department)
and also their own contact information (sometimes faxes are not
readable and need to be resent). 10/31 E-learning update: HW4 graded & HW3 regraded. Make sure your HW1, HW2, and HW3 grades are correct. HW1(AVG. 85, MED. 92), HW2(AVG. 90, MED 97), and HW3(AVG. 86, MED. 95) 10/30 Two pages of notes means 1 sheet of paper with writing
on both sides, or 2 sheets of paper iwith writing on only one side. 10/29 E-learning update: SimpleImageDemo.java is in the
Homework folder 10/29 Eclipse ASM plugin site: http://andrei.gmxhome.de/eclipse.
(There are several others on the web that do not have the latest
version, and thus won't work with the latest version of eclipse) 10/29 Exam
logistics: 10/27 E-learning update. Slides on the JVM have been
posted. 10/23 A HW4 Submission HELP has been added. 10/22 There are some changes at HW3 ExpectedResults. Please, use NewExpectedResults. The changes are for t12, t18, t21, t28, t29, and t42. Grading is not affected by this. The original attachment includes wrong version of ExpectedResult file. If you have any questions, please send me email. --KyungHee 10/22 Upcoming events: 10/22 E-learning
updates: 10/18 khkim@cise.ufl.edu).
Notice that Friday(10/24) is Homecoming day and there will be no
office hour. 10/16 10/15 E-learning updates: Slides on the Lambda
Calculus are available. 10/13 E-learning updates: HW3 & HW2_resubmission are graded. Check E-learning and send email to TA if you have any question. ExpectedResult, TestCases, and your result are attached to your HW3. Final grade for HW2 is updated also. 10/10 Elearning update: HW4 has been posted 10/9 There are some changes in HW3 Submission HELP. The email problem causes the delay of response to the question about "ToStringVisitor" class. You can implement your own ToStringVisitor to test your program and it doesn't need to match exactly with sample output. However, the tree contents should be identical to given one. Make sure to check the first line of previous sample output with "pico + ..." is removed. Your program will be tested using my ToStiringVisitor which is used to generate ExpectedResult as well, so you don't need to worry about the format of output once you correctly build the AST tree. 10/7 A HW3 Submission HELP has been added. 10/6 Hw3 problem 1 may not be clear due to
typos. Here is a revised version of the first 3 sentences that
should help. Consider the following grammar fragment
for simple assignment statements.
Note that this assumes the existence of a symbol table where
the declared type of variables has been inserted and can be obtained
with the lookup operation. Suppose
that the types are considered to be ordered boolean < int <
real. 10/6 Holders of department accounts are receiving
frequent emails asking for use name and password. DO NOT RESPOND
TO THESE EMAILS. Our staff will never ask you to send them your
password. The latest one looks like 10/5 E-learning updates: HW2_EDGE and HW1_Resubmit_EDGE graded. Check E-learning and send email to TA if you have any question. ExpectedResult, TestCases, and your result are attached to your HW2. HW1_EDGE grades are finalized to reflect resubmission result. 10/1 HW3 info: A new cop5555.ast.jar has been
uploaded. It is in the HW3 folder (not attached to the
assignment). The only difference is that the toString method has
been deleted from ASTNode.java. (You might find it helpful to
implement a simple toString visitor that will print out your AST, but
you are not required to do so.) 10/1 HW3 info: A couple of class names in the jar file for HW3 are not
exactly the same as given on the sheet with the AST syntax. Go
with the ones in the code.
10/1 E-learning updates: slides Types-2 and SML have
been posted.
9/29 HW SUBMISSION NOTICE
9/29 E-learning updates: HW1_Resubmission graded. The result is found at HW1_Resubmit attached file. In addition, HW1 grade is finallized to reflect all changes. If you see any mistake in HW1 final mark, send email to TA ASAP.
9/28 E-learning updates: HW2 graded. Check E-learning and send email to TA if you have any question. ExpectedResult, TestCases, and your result are attached to your HW2. 9/26 E-learning updates: HW3 assigned, Slides on Types
posted. 9/22 Clarification of project deadline. It is my
intent to have all homework due at 9am, but I neglected to change the
time from the e-learning default of 12pm while creating
HW2. So, for this assignment, if you are submitting
via HW2, you may have the 3 extra hours until 12pm (noon). Note
that e-learning often has a very heavy load at this time, so I
strongly recommend not waiting until the last minute to
submit. 9/22 E-learning update: Slides on Semantic
Analysis are available. 9/22 CISE
Career Workshop tonight at Touchdown Terrace, 6-10pm 9/21 E-learning updates: HW1_EDGE graded. Check E-learning and send email to TA if you have any question. ExpectedResult, TestCases, and your result are attached to your HW1. 9/18 TA's tomorrow(9/19, Friday) office hour is moved from 5:00pm to 11:00am for this week only. If you planned to see me and cannot make it at this time, please send me email(khkim@cise.ufl.edu). 9/16 A second homework Submission HELP has been added. 9/16 The test cases, expected result, and result of your grading are attached to your HW1 at E-learning. Line number and char position are optional, so I didn't check them while grading. Input 0123 is two tokens IntLin 0 and another IntLit 123 instead of Error. The resubmitted code will be graded in the same manner, and make sure your program produces the same number of tokens with exactly the same kinds. For example, if the desired token is one ErrorToken but you returned one Token with Kind ERROR, it'll be considered FAIL at that test case. 9/14 E-learning updates: HW1 graded. Check E-learning and contact TA if you have any question. 9/12 E-learning updates: HW2 has been
posted. Also, an assignment allowing HW1 to be resubmitted is in
the Homework/HW1 folder. Resubmission deadline is the same as
HW2--no late resubmissions will be accepted. 9/11 E-learning updates: Slides on Names, Scopes and
Binding have been posted along with an updated version of
Parsing-2. 9/8 A homework Submission HELP has been changed. Please, check this. 9/7 A homework Submission HELP has been added. 9/5 A homework FAQ has been
added. 9/3 Correction: The tokens are in the package cop5555.tokens 9/3 E-learning updates: Lecture slides
Parsing-2.ppt have been posted. Corrections to HW1: add keyword
"end" to enum in Token.java; delete mention of
StringLitToken in Scanner; fix colors of a couple of |s in the RE. 8/29 E-Learning updates: Lecture slides
Parsing-1.ppt are available in the slides folder. HW1 has been
added in the Homework folder. 8/25 Lecture slides for today and Wed are available in
E-learning. (Click on the bottom link on the left--you need your
gatorlink ID and password to log in.) The grade distribution in
the syllabus has been corrected. 7/30/08 Welcome to the web site
for COP5555. More information can be found by clicking on the
links on the left.
The final exam will be given to all on-campus students on the Dec.
17 from 7:30-9:30am, which is the date scheduled for this
course by the registrar. Please make your December
travel plans accordingly. (You can find out the registrar's
exam schedule for all of your courses from the course listings at http://www.registrar.ufl.edu/soc/.
Once you find the course, note the exam code, then look up the time
and day on the exam schedule page. )
Please, notice that the changes in TEST_MODIFIED.tar, specially in t7.class, t27.class, t29.class, t27.pico, and t29.pico.
Verify your HW5, HW6 grades are correct.
Those who already got 100 at HW7 don't need to submit HW7.
HW5 AVG:65.2, MED:75
HW6 AVG:87.4, MED:98
If you have any questions about grades, first verify your class behaves exactly the same as expected result, and then send me email khkim@cise.ufl.edu about which test case you are
questioning.
Since grading HW6 will take some time, you'd better start debugging your program by comparing
the execution result of your own generated class with ExpectedResult class.
My test sequence can be found from File TestSequence.
Image files used can be found here.
HW6 grading result will be announced as soon as possible.

@ File yourname has the result of compile, class generation, and execution.
@ RESULT_yourname.tar has the class files generated by your CodeGenVisitor.
@ Test.jar has four files,
ExpectedResult.tar which has class files generated by reference implementation,
TestCases.tar which has test pico files,
TestSequence which has test sequence I used, and
image files.
@ You need to compare the result of both executions. For example, to test t0.pico, you should do,
1. generate t0.class using your CodeGenVisitor,
2. run your t0.class by java t0 imageFile,
3. run reference implementation t0.class with same parameter, and see what's the difference.
You will be allowed two pages of notes,
otherwise the exam is closed book. The exam will start and end promptly so come a
few minutes early to ensure that you have the full time.
Bring a photo ID--I'll check this
during the exam. Edge students: your exams are usually
faxed--please use a pen or dark pencil. The exam will be
emailed to your proctor after the in-class students have taken
it. You have one week to take the exam and return it to me.
Friday is UF homecoming, so
class will not meet. The
midterm will be on Oct. 31. The deadline for
EDGE students is one week later, Nov 7. Anything covered in class up
to and including today may appear on the midterm.
Next week, we will use Monday and Wednesday to talk about the
Java Virtual Machine, ASM, and code generation. This is
necessary for HW5 and HW6 but will not be on the midterm.
Slides on denotational
semantics and Lisp and Scheme Exams from previous
years. Be aware that every semester is different, both in
the content and timing of the midterm, so it is possible you
will find material on a past midterm that we won't cover this
semester, or haven't covered yet. If that is the case,
ignore the question. Solutions to HW3 are in the
HW3 folder. Dear valued User,

Don't call System.exit at Scanner, SimpleParser, nor Parser.
(It's ok to call System.exit at IOException, but not SyntaxException or ErrToken case.)
Avoid using static field in your class unless you tested your class by calling multiple times. Always assume that the test driver will call Scanner|Parser several times for different test cases.
Download your cop5555.jar after submitting your HW, and make sure it's correct.
Before contacting the TA, check your submitted material first and make it clear what
your question is.
