Added './' to command invocations for scripts etc. Noted that the tests/ directory (or the files in it) were moved to entry directory. The same for variations/ files.

tac comes with a small suite of support programs to test and validate against.
|
|
Untar tests and variations in the same dir as the sources,
|
|
or change runtest.sh and unob.sh to look elsewhere for the keyword and test files.
|
|
|
|
keywords is a critical file, created from ioccc.kw.freq by mkkeywords.sh.
|
|
Only ioccc.kw.freq produces results compatible with iocccsize.c;
|
|
however, any of the variations can be used instead:
|
|
|
|
mkkeywords.sh c11 > keywords
|
|
|
|
unob.sh uses the same input file as mkkeywords.sh to control spaces after keywords.
|
|
The script allows an environment variable, KW, to override this.
|
|
Use it simply:
|
|
|
|
unob.sh prog.c | less
|
|
unob.sh -p prog.c | less
|
|
KW=c11 unob.sh prog.c | less
|
|
|
|
To handle obscure command line defines, use the environment variable DEF:
|
|
|
|
DEF="-D'g(o)'='goto o;'" KW=c11 unob.sh -p prog.c | less
|
|
|
|
It does an amazingly good job for such a simple script.

|
prog.c the reason for this README
|
|
keywords the file #included in prog.c, output of mkkeywords.sh
|
|
mkkeywords.sh reads one of the files from variations, produces string for prog.c
|
|
ioccc.kw.freq keywords used by iocccsize, sorted by frequency in 201x ioccc winners
|
|
unob.sh a more robust unobfuscation script; requires variations/c11 in cur dir
|
|
tokenfix.sh patches up prog -t output for ::, >>>, ...
|
|
src.doc.txt the answers, or at least significant help
|
|
tac.c more clearly written code, offered as a replacement of iocccsize.c
|
|
patch fixes single quotes in iocccsize.c, adds #ifndef, removes "I"
|
|
fixed_iocccsize.c iocccsize with patch applied, and nop -c argument added
|
|
|
|
tests/* moved to entry directory by judges
|
|
runtest.sh script to run the tests; ./runtest.sh | diff results -
|
|
results results without -k
|
|
results.k results with -k; opt=kcrs ./runtest.sh | diff results.k -
|
|
test*.c various test cases looking for compatibility
|
|
iocccbug*.c various test cases demonstrating problems with iocccsize
|
|
spotcheck.sh script to test a lot of files vs iocccsize
|
|
spotdiff.sh summarize the results of spotcheck.sh, showing only differences
|
|
discrepancies.md markdown file of the differences found using all the ioccc winning entries
|
|
|
|
to test prog:
|
|
|
|
./runtest.sh | diff - results
|
|
opt=kcrs ./runtest.sh | diff - results.k
|
|
find ~/src/obc -type f -a -name "*.c" | xargs spotcheck.sh ./prog
|
|
[ | ./spotdiff.sh | diff -bw - discrepancies ]
|
|
|
|
to test tac:
|
|
|
|
prog=tac ./runtest.sh | diff - results
|
|
prog=tac opt=krs ./runtest.sh | diff - results.k
|
|
find ~/src/obc -type f -a -name "*.c" | xargs ./spotcheck.sh tac
|
|
|
|
variations/* as described in the remarks, and in each file below, also moved to entry directory by judges
