Marko (mainly),
How does the sub styles idea work.?
In commit 1209, where is the sub-styles? at \examples\styles I can see the default and noname styles. In the info file of the default style I can see
base-style=contours_ft base-style=location base-style=waters
Is this the sub-styles that will be included in the default style?
Where are these sub-styles though? I forgot that a .jar is actually an archive, and when I went further into it with 7Zip I found the styles where it always are: mkgmap-r2109.tar.gz\mkgmap-r2109.tar\mkgmap-r2109\mkgmap.jar\styles\
Suppose an included base-style treats an element a certain way, will the main style (default in this case) then ignore this element? So the base-style treatment overrides the main style? Will a continue statement in the base style then reverse this, so that the main style treatment will prevail?
Then, in the case of 3 sub styles, if they all have actions for the same element: the first style will be used, and the rest ignored unless a continue statement is used in the previous style? A continue statement will have no effect if the previous sub style did not have a continue statement?
Or should conflicting rules be avoided?
Argh, I hope someone understand what I mean?
I don't use the default style, but a style based on the default with a couple of tweaks for custom points& lines etc. Still I like to keep updating regularly to benefit from Marko's improvement in the style. So I copy my tweaks into the latest default styles manually. The sub style idea might make my manual operation unnecessary, if I can just include my own style into the default. Before any other included styles, if I understand it correctly.
