Hi, The Apple HFS/HFS+ resource fork in source code should not check by very-long-line-length-in-source-file. One example: https://sources.debian.org/src/libicns/0.8.1-3.1/samples/test2.rsrc/ file test2.rsrc test2.rsrc: Apple HFS/HFS+ resource fork, map offset 0x95fe, map length 0x3c, data length 0x94fe, nextResourceMap 0xe9084, fileRef 0x5a, list offset 0x1c, name offset 0x32, 1 type, 0x69636e73 'icns' * 1 resource offset 0xa
