I've seen this library. It parses using constexpr, while Metaparse uses
template metaprograms. I can't see how one could do the following using
- generate template metafunction classes as the result of parsing that
are immediately callable (build a DSL for metaprograms)
- printf argument verification (by parsing the format string) at
- create types as the result of parsing
One of the examples of Metaparse (constexpr_parser) demonstrates how to
combine a parser based on constexpr functions with ones based on
template metaprogramming. It is a parser for an "a* b* a*" grammar and
parses the "a*" parts using metaprograms and the "b*" parts using
The documentation of Metaparse describes the difference as well
