Hi, I've created a version of Metaparse that depends on the Boost libraries only. I request this version of Metaparse be placed in the queue for formal review. The zipped source code can be found here: http://abel.web.elte.hu/metaparse/metaparse.zip The documentation can be found here: http://abel.web.elte.hu/metaparse/metaparse The library has been tested on the following compilers: - GCC 4.6 (with and without -std=c++0x) - GCC 3.4 - Clang 2.9 - Visual C++ 10 A quick summary: Metaparse is a library for constructing parsers parsing at compile-time based on template metaprogramming. The parsers built with the library take boost::mpl::strings as input and can produce - types - objects (types with public static members) - callable C++ functions (types with public static method) - template metafunction classes as output (based on the input being parsed). On compilers supporting constexpr the library provides the following syntactic sugar for writing the input of the parsers: BOOST_STRING("this is a string") The library can be used for implementing DSLs in C++, including DSLs making C++ template metaprogramming easier (see examples).
