| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `flag' contains several categories of attributes and it makes us confusion (at least, I had confused). * rb_method_visibility_t (flags::visi) * NOEX_UNDEF -> METHOD_VISI_UNDEF = 0 * NOEX_PUBLIC -> METHOD_VISI_PUBLIC = 1 * NOEX_PRIVATE -> METHOD_VISI_PRIVATE = 2 * NOEX_PROTECTED -> METHOD_VISI_PROTECTED = 3 * NOEX_SAFE(flag)) -> safe (flags::safe, 2 bits) * NOEX_BASIC -> basic (flags::basic, 1 bit) * NOEX_MODFUNC -> rb_scope_visibility_t in CREF * NOEX_SUPER -> MISSING_SUPER (enum missing_reason) * NOEX_VCALL -> MISSING_VCALL (enum missing_reason) * NOEX_RESPONDS -> BOUND_RESPONDS (macro) Now, NOEX_NOREDEF is not supported (I'm not sure it is needed). Background: I did not know what "NOEX" stands for. I asked Matz (who made this name) and his answer was "Nothing". "At first, it meant NO EXport (private), but the original meaning was gone." This is why I remove the mysterious word "NOEX" from MRI. * vm_core.h: introduce `enum missing_reason' to represent method_missing (NoMethodError) reason. * eval_intern.h: introduce rb_scope_visibility_t to represent scope visibility.
