[mkgmap-dev] conditional includes in style

Thu Mar 27 16:51:12 GMT 2014

First, the conditional rules or includes sounds like a good idea. I 
guess we should only allow the new syntax for key=value or maybe key=*.

Should we introduce a new type of keys (global keys) that are not 
associated with any OSM object?

Or, should the global keys be the default on every object? For example, 
after

java -jar mkgmap.jar --add-default-way-tag=name=unknown

every OSM way that did not already carry a name=* tag would be tagged 
with name=unknown.

; would be a bad choice for a delimiter, because it is a shell 
meta-character in the conventional Unix shells (separating commands when 
you do not want to use line breaks).

Also, I think that the option should be split already on the command 
line, like this:

java -jar mkgmap.jar --style-option=topo --style-option=cycleways ...

In many Unix shells, you can use short-hand notation which would be 
expanded to the above by the shell:

java -jar mkgmap.jar --style-option={topo,cycleways}
