DeltaCode is a tool to compare and report scan differences. It takes JSON files as an input which is the output of ScanCode-toolkit as well. When comparing files, it only uses the exact comparison. By exact comparison, I mean it compares the hash value of the files. The output of DeltaCode is a JSON/CSV file which includes the details of the scan such as delta score, delta count, etc. The goal of this project is to improve the usefulness of the delta by also finding files that are mostly the same (e.g. quasi or near duplicates) vs. files that are completely different. After this project, DeltaCode would be able to detect similar files in a directory approximately.
