The "Synalyze It!" grammar format is XML, and the developer has some sample grammars for download: https://www.synalysis.net/formats.xml https://www.synalysis.net/formats.xml Having wanted a binary grammar format for a while, and just purchased the Pro version of "Synalyze It!" as a starting point, it would be interesting to hear a short non-specialist's summary of the relative merits of your approach to expressing grammars compared with an XML based approach like "Synalyze It!" ... Overall, "Synalyze It!" seems mostly fairly stable and certainly a useful tool well worth the purchase price for the Pro version. However, it is closed source, by a small developer, on a single platform: would much prefer to rely on something with source code available ...

The dev is on github, https://github.com/synalysis https://github.com/synalysis send him a push request?

  Thanks, I did not know he was on github. But does he have a repository for "Synalyze It!"? I cannot see one. It looks like he has open sourced some supporting frameworks ... edit: grammar

    Would he still get paid if he gave is code away?

What if you compared two descriptions side by side? What about PNG, for which a grammar exists for both: https://www.synalysis.net/Grammars/png.grammar https://www.synalysis.net/Grammars/png.grammar v. https://raw.githubusercontent.com/binspector/binspector/master/bfft/png.bfft https://raw.githubusercontent.com/binspector/binspector/mast... Anything I'd say at this point would be biased, but I would be interested in continuing the conversation.

  A comparison w.r.t. the PNG grammar sounds like an excellent starting point. I could see educational value (and more) in attempting a bi-directional translator between the two grammar formats.

Or, maybe a better question is what grammars are you currently using Synalyze It! for? I have used Binspector for fairly complex file formats and it has held up for my purposes in the past. Would it be worth an hour or two to see if Binspector could pass muster?

  The grammars are for various 2D & 3D CAD model formats. Some can be fairly complicated, and the data files can be fairly large. For clarity, I'm bootstrapping something and don't have any immediate plans to open source the grammars. Certainly, it would be worth looking at Binspector. Probably it would take me a couple of days to get up to speed though, and that is not time that I have immediately.
