[spirit] A trait to access encoding-specific parsers

Reported by: Andrey Semashev Owned by: Hartmut Kaiser
Milestone: Boost 1.43.0 Component: spirit
Version: Boost 1.44.0 Severity: Not Applicable
Keywords: Cc:

Description

Originated from ​this discussion.

The attached patch allows to gain access to the encoding-specific parsers by specifying the encoding type to the encoding_specific template parameter. This allows the following use case: 

  template< typename CharT >
  void parse(const CharT* str)
  {
    typedef typename my_traits< CharT >::encoding encoding;
    typedef spirit::encoding_specific< encoding > parsers;
    qi::parse(str, *parsers::char_);
  }
