[mkgmap-dev] Append Name with general rules via style-file

Fri Aug 7 14:40:47 BST 2009

Hi Felix,

I am trying to work out what doesn't work here.  In general
anything that relies on the order that actions are run in
will not work reliably (see my previous post).

I will put each question/comment in a separate post to keep
things clear and separate.

The following part of the file could be much reduced:

> mtb:scale=0 & mtb:scale:uphill=0 & route=mtb { name 'mtbrt00 ${name}' |
> 'mtbrt00' }
> mtb:scale=0 & mtb:scale:uphill=1 & route=mtb { name 'mtbrt01 ${name}' |
> 'mtbrt01' }

To the following which says 'if either mtb:scale or mtb:scale:uphill
are given then construct the name from the values.  If either one
is absent, replace it with a dot'.

Does that accurately reproduce what you want?  I realise that might
not currently work with other things in the file, but I am trying to
take this a step at a time.

(mtb:scale=*  | mtb:scale:uphill=*) & route=mtb
	{ name 'mtbrt${mtb:scale|def:.}${mtb:scale:uphill|def:.} ${name}'
          | 'mtbrt${mtb:scale|def:.}${mtb:scale:uphill|def:.}'
	}

(mtb:scale=* | mtb:scale:uphill=*) & route!=mtb
	{ name 'mtb${mtb:scale|def:.}${mtb:scale:uphill|def:.} ${name}'
  		 | 'mtb${mtb:scale|def:.}${mtb:scale:uphill|def:.}'

If there are invalid values for mtb:scale, then this will give different
results for that case, but if that is important then perhaps we
can deal with that separately.
