2224 : : //! \brief Ensure that a grammar only uses keywords from a pool of
2225 : : //! pre-defined keywords
2226 : : //! \details In grammar definitions, every keyword should be wrapped around
2227 : : //! this use template, which conditionally inherits the keyword type its
2228 : : //! templated on (as defined in Control/Keywords.h) if the keyword is listed
2229 : : //! in any of the pools of keywords passed in as the required pool template
2230 : : //! argument and zero or more additional pools. If the keyword is not in any
2231 : : //! of the pools, a compiler error is generated, since the struct cannot
2232 : : //! inherit from base class 'char'. In that case, simply add the new keyword
2233 : : //! into one of the pools of keywords corresponding to the given grammar.
2234 : : //! The rationale behind this wrapper is to force the developer to maintain
2235 : : //! the keywords pool for a grammar. The pools are brigand::set and are
2236 : : //! used to provide help on command line arguments for a given executable.
2237 : : //! They allow compile-time iteration with brigand::for_each or
2238 : : //! generating a run-time std::map associating, e.g., keywords to their help
2239 : : //! strings.
2240 : : //! \warning Note that an even more elegant solution to the problem this
2241 : : //! wrapper is intended to solve is to use a metaprogram that collects all
2242 : : //! occurrences of the keywords in a grammar. However, that does not seem to
2243 : : //! be possible without extensive macro-trickery. Instead, if all keywords
2244 : : //! in all grammar definitions are wrapped inside this use template (or one
2245 : : //! of its specializations), we make sure that only those keywords can be
2246 : : //! used by a grammar that are listed in the pool corresponding to a
2247 : : //! grammar. However, this is still only a partial solution, since listing
2248 : : //! more keywords in the pool than those used in the grammar is still
2249 : : //! possible, which would result in those keywords included in, e.g., the
2250 : : //! on-screen help generated even though some of the keywords may not be
2251 : : //! implemented by the given grammar. So please don't abuse and don't list
2252 : : //! keywords in the pool only if they are implemented in the grammar.
2253 : : //! \see For example usage see the template typedef
2254 : : //! walker::cmd::use in Control/Walker/CmdLine/Grammar.h and its keywords
2255 : : //! pool, walker::ctr::CmdLine::keywords, in
2256 : : //! Control/Walker/CmdLine/CmdLine.h.
2257 : : //! \see http://en.cppreference.com/w/cpp/types/conditional
2258 : : //! TODO It still would be nice to generate a more developer-friendly
2259 : : //! compiler error if the keyword is not in the pool.
