it as a proof of concept, and because I'm stuck in this "exposing
types" problem since a long time...)
Could you elaborate on what problems you have with exposing types ? What
exactly did you try that didn't work ?
As an example, on line 38 of this code
http://glm.g-truc.net/api-0.9.1/a00127_source.html is the definition
of vec2. All glm types are pretty similar to this and if I could have
some insights on how to wrap something like this the rest would be
almost "not very hard" for me to do.
tvec2 itself isn't a type. You need to instantiate it to get a type that
you can expose to Python. Then the normal rules should work just fine:
class_<tvec2<float> > f_tvec2("fvec2");
float (tvec2<float>::*swizzle_1)(comp) = &tvec2<float>::swizzle;
f_tvec2.def("swizzle", swizzle_1);
I assume you'd like to do this for many different value-types, so it
might be best to wrap this in a function template:
template <typename T>
void define_vec2(char const *name)
{
typedef tvec2<T> vec2_type;
class_<vec2_type> vec2(name);
float (vec2_type::*swizzle_1)(comp) = &vec2_type::swizzle;
vec2.def("swizzle", swizzle_1);
//...
}
and then call that function for all the value-types you want:
define_vec2<float>("fvec2");
define_vec2<int>("ivec2");
//...
HTH,
Stefan
