Hi,
I have been reading the discussiong here about adding the support for unicode.
Maybe there is a solution which would allow to have templated versions of
relevant classes AND static library in one box.
If we decide that specialization for char and wchar_t is sufficient, the headers
can contain generic template based declarations, but the implementation will be
given only for particular cases ( char and wchar_t ) and so it can be included in
the static lib.
Similar idea is used in stl for streams, strings and locales.
An Example:
aclass.hpp -----------------
template< typename T >
class AClass
{
...
// Declaration of a member function
bool dosomething( std::basic_string<T> );
...
};
aclass.cpp -----------------
bool AClass<char>::dosomething( string )
{
return false;
}
bool AClass<wchar_t>::dosomething( wstring )
{
return true;
}
-----------------------------------
Because definition of the member function in the .cpp are not templated,
they can reside in the static library.
With a help from preprocessor, it should be easy to define two variants
in one place.
Also that could a possibility, that the .cpp file will be included as headers
all this can be done using macros.
Example 2:
aclass.inl -------------------
TEMPLATE_DEF
bool AClass<TEMPLATE_T>::dosomething( std::basic_string<TEMPLATE_T> )
{
return false;
}
aclass.cpp ------------------
#define TEMPLATE_T char
#define TEMPLATE_DEF
#include "aclass.inl"
#undef TEMPLATE_T
#undef TEMPLATE_DEF
#define TEMPLATE_T wchar_t
#define TEMPLATE_DEF
#include "aclass.inl"
#undef TEMPLATE_T
#undef TEMPLATE_DEF
aclass.hpp -----------------
template<T>
class AClass
{
...
};
...
#ifdef LIB_INLINE
#define TEMPLATE_T T
#define TEMPLATE_DEF template< typename T >
#include "aclass.inl"
#undef TEMPLATE_T
#undef TEMPLATE_DEF
-----------------------------
This way everybody can be satisfied with a reasonable effort.
