Plot twist: the publisher just looked into the future. I’m currently building an EBNF parser for my project, C³ (C cubed), which allows you to define arbitrary grammar at the very beginning of a file to seamlessly mix strings and syntax from Python, JS, or any custom DSL.
While C++ was just a simple iteration, C³ aims to be a paradigm shift. If you see JavaScript DOM manipulation code on a C++ book cover, it’s not a stock photo blunder anymore — it’s just a valid source file after a custom EBNF header. The project is currently in private development, but I'm considering launching it as an online service. Stay tuned!
The repo readme doesn't mention anything like that. It looks an ambitious project. I think the AI-style tone in the readme, or things like 'paradigm shift' and that it would be an online service (for a language? huh?) may be contributing to the downvotes you're getting.
