NIL is a clone detector using N-gram, Inverted index, and LCS. NIL provides scalable large-variance clone detection. Requirements JDK 11+ Options -s, --src Input source directory. You must specify the target dir. -mil, --min-line Minimum number of lines that a code fragment must be to be treated as a clone. default: 6 -mit, --min-token Minimum number of tokens that a code fragment must be to be treated as a clone. default: 50 -n, --n-gram N for N-gram. default: 5 -p, --partition-size The number of partitions. default: 10 -f, --filtration-threshold Threshold used in the filtration phase (%). default: 10 -v, --verification-threshold Threshold used in the verificatioin phase (%). default: 70 -o, --output Output file name. default: result_{n}_{f}_{v}.csv -t, --threads The number of threads used for parallel execution (both the Preprocess and Clone detection phases). default: all threads -bce, --bigcloneeval If you specify -bce option, NIL outputs result file feasible to BigCloneEval. default: false -mif,--mutationinjectionframework If you specify -mif option, NIL outputs nothing except for the output file name as standard output. default: false
