[mkgmap-dev] [Patch v1] improve mdr7 index

Wed Apr 5 17:03:08 BST 2017

that looks more useful. I don't think reporting is needed - you can check
if things are working in the map themselves - so it should be only in some
kind of debug mode.

Could there be a wildcard like "?". I have thinks like M?? for M00 to M66.
Of course I could add all combinations into  the file so I'm not sure if a
wildcard like ? is a good idea. Maybe have ? not as wildcard but escaped
"^?" as wildcard? Then I could simply have M^?^? as a rule in mdr-7-del
instead of putting in all the possible combinations. I guess allowing ^* as
wildcard would be a bit too strong though - and I guess should not be
allowed?
