Hi everyone! Merry Christmas and happy new year! I'm making a modernized BNF-style metalanguage that supports grammars for text and binary formats, but unless there's some kind of outside review, I won't find any blind spots I have until long after release. If you have experience in grammars or protocols (text or binary), could you take a quick look? Note: I'm not aiming for perfect expressivity; just 80-90% of use cases without making things overcomplicated so that it can be used descriptively in documentation. https://ift.tt/VElSQC1 Some examples of it in use: * Internet Prodocol, version 4: https://ift.tt/gmKRZbA * Concise Text Encoding: https://ift.tt/wHQnfiZ * Concise Binary Encoding: https://ift.tt/9rpSwuB * The KBNF grammar itself: https://ift.tt/lSbWtq6
