https://svn.boost.org/trac10/ticket/6106 <p> qi::symbols is an exceptionally useful parser, but it is strongly tied to character strings as its input type. When doing binary parsing, one of the common tasks is de-serializing objects from the binary stream, an activity which can strongly benefit from Nabialek trick (<a class="ext-link" href="http://boost-spirit.com/home/articles/qi-example/nabialek-trick/"><span class="icon">​</span>http://boost-spirit.com/home/articles/qi-example/nabialek-trick/</a>). Another common use case are extensible enum types, a feat which is somewhat cumbersome to handle with attribute transformations. </p> <p> This is my first attempt at implementing a qi directive, so it's probably far from perfect. One of the immediate shortcomings I want to resolve is direct dependency on std::map which is also passed by value between instances. </p> <p> The implementation and a short example demonstrating Nabialek trick is attached. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/6106 Trac 1.4.3 oakad@… Tue, 08 Nov 2011 19:17:26 GMT https://svn.boost.org/trac10/ticket/6106 https://svn.boost.org/trac10/ticket/6106 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">map.hpp</span> </li> </ul> <p> Implementation of the map[] directive in the repository::qi namespace </p> Ticket oakad@… Tue, 08 Nov 2011 19:18:14 GMT https://svn.boost.org/trac10/ticket/6106 https://svn.boost.org/trac10/ticket/6106 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">test_map1.cpp</span> </li> </ul> <p> Example showing use of map[] to implement Nabialek trick </p> Ticket Joel de Guzman Tue, 08 Nov 2011 23:18:31 GMT
