Projects / Spirit Parser library

Spirit Parser library

Spirit is an object-oriented, recursive descent parser generator framework implemented using template meta-programming techniques. Expression templates allow Spirit to approximate the syntax of Extended Backus Normal Form (EBNF) completely in C++. The Spirit framework enables a target grammar to be written exclusively in C++. EBNF grammar specifications can mix freely with other C++ code and, thanks to the generative power of C++ templates, are immediately executable.

            It does. Everyone calls it Backus Naur Form, except Peter Naur. See Backus Normal Form vs. Backus Naur Form:
