[mkgmap-dev] default style lines enhancements

Sat Jul 25 09:28:39 BST 2020

Hi Ticker,

ok, most of the changes look plausible to me, but I see no need to add the lines for razed / disued / abandoned etc. railways. I would comment these two lines:
abandoned:railway=* | demolished:railway=* | removed:railway=* | razed:railway=* | was:railway=* | historic:railway=* {add railway=lifecyclePrefix}
railway=* & railway!=miniature & railway!=proposed & tunnel!=yes & highway!=* & is_closed()=false [0x19 resolution 22]

I am also not sure about the routable lines for amenity=parking. Even with the test reg. connected this probably creates lots of routing islands. As a mapper, I've never cared to connect those areas to the road network, but I know that other mappers do this. Is it meant to improve pedestrian routing?

Hi Gerd

It can only be:
  ${tagname|filter:args}
or
  ${tagname|filter1:"arg with spaces"}

and, for the subst filter, the from=>to counts as a single arg.

In the example:
  ... '${ref|subst: =>} ${mkgmap:dest_hint|subst:;=> |subst:/=> }'
spaces are insignificant either side of the first | and before the :
but are significant after the : and before subsequent |.

The style manual says:
 If the argument contains spaces or symbols it should be quoted.
   For backward compatibility, most cases where you have spaces or
 symbols do not actually need to be quoted, however we would
 recommend that you do for clarity.  If you need a pipe symbol
 or a closing curly backet, then you must use quotes.
