NAME¶

typename_macro, pretty_typename_macro - type demangler and pretty printer

DESCRIPTION¶

These preprocessor macro-definitions are useful when dealing with complex types as generated by imbricted template technics: they print in clear a complex type at run-time. typeid_name_macro obtains a human readable type in a std::tring form by calling the system typeid function and then a demangler. When this type is very long, pretty_name_macro prints also it in a multi-line form with a pretty indentation.

EXAMPLES¶

  typedef map <size_t, double, less<size_t>, heap_allocator<pair<size_t,double> > >  map_type;


  cout << typeid_name_macro (map_type);

IMPLEMENTATION¶

extern std::string typeid_name (const char* name, bool do_indent);
} // namespace rheolef
/// @brief get string from a type, with an optional pretty-printing for complex types
#define        typename_macro(T) rheolef::typeid_name(typeid(T).name(), false)
#define pretty_typename_macro(T) rheolef::typeid_name(typeid(T).name(), true)
/// @brief get string type from a variable or expression
template <class T> std::string        typename_of (T x) { return        typename_macro(T); }
template <class T> std::string pretty_typename_of (T x) { return pretty_typename_macro(T); }
