Using boost-spirit to parse string to struct of QStrings
WebIntroduction. Boost Spirit is an object-oriented, recursive-descent parser and output generation library for C++. It allows you to write grammars and format descriptions using a format similar to Extended Backus Naur Form (EBNF) [2] directly in C++. These inline grammar specifications can mix freely with other C++ code and, thanks to the ... WebIostreams: Boost.IOStreams provides a framework for defining streams, stream buffers and i/o filters.

Spirit: LL parser framework represents parsers directly as EBNF grammars in inlined C++. WebExample 11.9 uses boost::spirit::qi::int_ to parse an integer, then writes that integer to standard output. That’s why an action has been linked with boost::spirit::qi::int_.Actions are functions or function objects that are called when a parser is applied. Linking is done with the operator operator[], which is overloaded by boost::spirit::qi::int_ and other parsers. instrument approach procedures faa
