Hi Andrzej, okay, I can add the 2nd test as well. I wonder if we should disallow to modify the special tags. That would allow to remove rules which would can never be true instead of adding and evaluating the tags for each element. On the other hand, the current patch is very simple, the improved version would require more code. Just an idea..

You have implemented warnings other way, than I have expected. It's good but you still can add another check: for each tag in styleOptionTags check, if tag exist in style. Or maybe if tag is used? If not, then something could be wrong - user have put option in command line, which is ignored. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
