v_2_0_cpp_x3_parse

Iterator based parser/unpacker using Spirit.X3 (experimental)

What is this?

It is a new parser using Boost.Spirit.X3(experimental). Boost.Spirit.X3 is experimental feature, so the iterator based parser/unpacker is also an experimental feature.

Here is the parser code.

See https://github.com/redboltz/msgpack-c/blob/x3_parse/include/msgpack/v2/x3_parse.hpp

It is quite small. It is completely separete from existing parser/unpacker. The existing parser/unpacker takes the pointer and the size of buffer, but iterator based unpacker/parser takes begin/end iterator pair.

How to use?

Define MSGPACK_USE_X3_PARSE before including msgpack.hpp. It is usually defined via a compiler option such as -DMSGPACK_USE_X3_PARSE.

Requirements

• Boost 1.61.0 or later
• C++14 support.
