Welcome to Spirit
Spirit is a set of C++ libraries for parsing and output generation
implemented as Domain Specific Embedded Languages (DSEL) using
Expression templates and Template Meta-Programming. The Spirit
libraries enable a target grammar to be written exclusively in C++.
Inline grammar specifications can mix freely with other C++ code and,
thanks to the generative power of C++ templates, are immediately executable.
Spirit is part of Boost Libraries, a
peer-reviewed, open collaborative development effort.
