using date:ParseDate(value, wx.wxString_const_iterator())
seems to work but looking into the run time we see that the pointer to the
iterator is a bad pointer not very desirable.
supporting a single argument seems preferable.
The following code works.
static int LUACALL wxLua_wxDateTime_ParseDate(lua_State *L)
{
// wxString date
wxString date = wxlua_getwxStringtype(L, 2);
// wxString::const_iterator end
wxString::const_iterator * end;
if (lua_type(L, 3) == LUA_TNONE)
// missing argument
end = &(wxString::const_iterator)date.end();
else
end = (wxString::const_iterator *)wxluaT_getuserdatatype(L, 3,
wxluatype_wxString_const_iterator);
but a similar change would be needed for each function expecting an optional
iterator.
currently wxlua_getwxStringtype does not seem to handle a missing argument.
If it returned NULL we could trigger on the result.
maybe a special function
end = GetOptionalIterator(L, 3, date);
which returns the_iterator || &date.end() could be used.
