My experience with parsing undocumented binary formats is with Skia's skp files. Unfortunately they don’t publish any docs regarding the format. Instead I relied on their source code (which is very convoluted), and in that process I discovered two tools which proved pretty useful: - Kaitai [1], which takes as input a YAML file and can parse binary files based on it (and even generate parsers). - ImHex [2], which has a pattern language [3] which allows parsing, and it seems more powerful than what Kaitai offers. I stumbled upon some limitations with it but it was still useful. [1]: https://kaitai.io/ [2]: https://github.com/WerWolv/ImHex [3]: https://docs.werwolv.net/pattern-language/ |
