This looks interesting. I created and maintain a library for INI parsing that got surprisingly popular -- it's tiny, so is good for embedded systems. This API has a very similar feel to mine, including the callback for every key/value pair with a void* userdata. https://github.com/benhoyt/inih
- The companion GitHub repository
From my experience, maintaining a standalone/embedded printf library - MISRA is a combination of two things: Common-sense rules, and pain-in-the-ass rules. Example of the latter: Avoiding implementation-defined types like `int` in places where my code doesn't care about what sizeof(int) is.
I was able to accommodate most (?) of the MISRA rules (https://github.com/eyalroz/printf/issues/77), but mine is just a small library, so I don't know how restrictive they would be for a larger codebase.
