Question

Would you please help me getting back the typename of the original object put into a boost::variant?

I have something like this

typedef boost::variant<macro,module> ref_var;

Is it possible to get back the typename of the original object? In this case (macro or module)

I was trying to get it using

typeid(v).name()

but it gives me weird name that is neither macro nor module:

PN5boost7variantI5macro6moduleNS_6detail7variant5void_ES5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_S5_EE

Would you please help?

If all you need is to get back the textual representation of the types held in a variant, you can roll your own solution:

const char* ref_var_typename(const ref_var& v) {
    static const char* types[] = { "macro", "module" };
    return types[v.which()];
}
