This PR removes the
Ex
variants of various formatter functions. Their functionality is instead integrated into the non-Ex
variant. Having theEx
variants effectively doubled the complexity of our public formatter interface and each only had a single additional argument. This additional argument can trivially be passed with asNULL
, which I believe should be intuitive to most seasoned C programmers.When porting the various examples I varied between using
NULL
andZYAN_NULL
. I chose one or the other depending on whether the example otherwise prefers Zycore or standard C constructs. We should probably normalize that across all examples at some point.
