CI-lab

This is the code base for CS429 S2023 CI lab. Check the writeup for more details.

Files

Files should be included in handout:

tests/
ansicolors.h
ci_reference
ci.c
ci.h
driver.sh
err_handler.c
err_handler.h
eval.c
handle_args.c
interface.c
lex.c
Makefile
node.h
parse.c
print.c
token.h
type.h
update.sh
value.h
variable.c
variable.h

• Students are required to complete eval.c and variable.c.

• ci_reference is a compiled reference program executable provided to students. driver.sh <filename> runs ci and ci_reference and compares their outputs.

• tests/ holds the testcases provided to students. Students are required to pass all testcases in test_week1.txt for week 1.

Program

• Run make ci to get the binary ci. Run make test_week# to run the simple grader on a given week's test cases.

• ci takes two optional arguments:

  ./ci -i <infile> -o <outfile>
  

  The infile can also be fed from stdin with ./ci < <infile>. The outfile is only used for grading, where the formatting stuffs are removed.

• The interactive prompt of ci takes two special commands:

  • @q to quit the program
  • @p to print all defined variables (EEL-2)
