Gary Vaughan wrote an extensible printf library:
https://savannah.nongnu.org/projects/libsnprintfv/
that features the ability to register callback functions
for various formatting characters.  The extensions are
pretty easy.  My crucial requirement was to have an
argv style of interface, so for every "v*printf" interface,
this library also has a "*printfv" interface.

It isn't very active because it works pretty well (leastwise
for the way I use it).
