Also, in ldebug.c, why not replace
int luaG_ordererror (lua_State *L, const TObject *p1, const TObject *p2) {
const char *t1 = luaT_typenames[ttype(p1)];
const char *t2 = luaT_typenames[ttype(p2)];
if (t1[2] == t2[2])
luaG_runerror(L, "attempt to compare two %s values", t1);
else
luaG_runerror(L, "attempt to compare %s with %s", t1, t2);
return 0;
}
by something more like
int luaG_ordererror (lua_State *L, const TObject *p1, const TObject *p2) {
int t1 = ttype(p1);
int t2 = ttype(p2);
if (t1 == t2)
luaG_runerror(L, "attempt to compare two %s values",
luaT_typenames[t1]);
else
luaG_runerror(L, "attempt to compare %s with %s",
luaT_typenames[t1], luaT_typenames[t2]);
return 0;
}
or did I miss something? :)
Thomas.
