Hence, we were left with …
... and the standard UNIX tool zipinfo cannot display them !
So here is Python one-liner to extract them, and other useful meta informations:
python -c "import json, sys, zipfile; json.dump([{k: str(getattr(i, k)) for k in zipfile.ZipInfo.__slots__} for i in zipfile.ZipFile(sys.argv[1]).infolist …Say you are generating a colored diff output with the standard difflib Python package:
diff = difflib.ndiff(file1_lines, file2_lines)
print('\n'.join(diff))
Now, I'll show you how to write a simple color_diff function that you can use to color your diff like this:
diff = difflib.ndiff(file1_lines, file2_lines)
