No realistic discussion of such a proposal can be undertaken with reference to/ comparison with boost.spirit which has been in usage for 10 years and has been continually updated, enhanced and maintained over that period. You should start out by taking a careful look at spirit and contrast your proposal with this mature library used for the same purpose.

I know boost.spirit, but it doesn't solve the same problem: boost.spirit creates a parser for parsing at run time, whereas my 'library' creates a parser that parses string literals at compile time (it could parse a string at run time as well, but it's not meant for that). For example, this is an excerpt from main.cpp: constexpr const_string< char > cstr = "2 + 54 * 2 + 83"; constexpr addition a( cstr );//cstr is processed at compile time static_assert( a.eval() == 193 , ""); -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de
