[mkgmap-dev] tag value within regular expression

Wed Jan 26 09:42:48 GMT 2022

Hi Mike

It needs to be something like:

highway=* & name=* {set temp='${name|not-contained:" :rn"'}
# the separator char                                ^
# now temp will be set to name or null and can be tested:
highway=* & temp=* {echotags "name not in route"}

Think I've got this right.

I'll adjust the style manual layout sometime
