[mkgmap-dev] Exit_hint and Dest_hint result is not what I was expecting

Sat Mar 19 17:51:52 GMT 2016

No, echotags expects a string constant as parm, and it prints all tags of an object

Since the result string was:
Exit 18 Beck Rd ~ Beck Road

The only place in the code with a "~" is

line 89
'${destination:street} ~ ${destination}' |

Can I use echotags to display the actual value of a variable

{echotags ${destination}) ?

Hi Greg.

when mkgmap:dest_hint=true matches than mkgmap has either found a destination tag in the OSM

data or it has filled destination with one of the alternative values like

destination:forward, destination:street, destination:lanes and so on.

Maybe that is not a good idea, maybe mkgmap should fill a prefixed varible instead.

Does that help?

I have an exit with a highway=motorway_link and destination:street=Beck Road. I have a node with highway=junction and ref=18.

I was trying to get:
Exit 18 Beck Rd

But I am getting:
Exit 18 Beck Rd ~ Beck Road

My line file contains:

dest_hint=* { delete dest_hint }
highway=* & mkgmap:dest_hint=true { set destination:ref = '${destination:ref|subst:South=> S|subst:North=> N|subst:East=> E|subst:West=> W|subst:I =>I-|subst:M =>M-|subst:US =>US-}';
set destination = '${destination|subst:/=>,}';
set destination:street = '${destination:street|subst:;=>,|subst: Road=> Rd|subst: Street=> St|subst: Avenue=> Ave|subst: Mile=> Mi|subst: Boulevard=> Blvd|subst: Parkway=> Pkwy|subst: Highway=> Hwy|subst: Southwest=> SW|subst: Northwest=> NW|subst: Southeast=> SE|subst: Northeast=> NE}';
}

(highway=motorway_link | highway=trunk_link | highway=primary_link | highway=secondary_link | highway=tertiary_link) & mkgmap:dest_hint=true
  { set dest_hint = '${destination:ref} ${destination:street} - ${destination}' |
'${destination:ref} ${destination:street}' |
'${destination:street} ~ ${destination}' |
'${destination:ref} ^ ${destination}' |
'${destination:street}' |
'${exit_hint_ref|subst: South=> S|subst: North=> N|subst: East=> E|subst: West=> W} ${exit_hint_name|subst: Road=> Rd|subst: Street=> St|subst: Avenue=> Ave|subst: Mile=> Mi|subst: Boulevard=> Blvd|subst: Parkway=> Pkwy|subst: Highway=> Hwy}' |
'${exit_to|subst: Road=> Rd|subst: Street=> St|subst: Avenue=> Ave|subst: Mile=> Mi|subst: Boulevard=> Blvd|subst: Parkway=> Pkwy|subst: Highway=> Hwy}' |
'${destination}';
       }
# build exit hint
exit_hint=* { delete exit_hint }
(highway=motorway_link | highway=trunk_link | highway=primary_link | highway=secondary_link | highway=tertiary_link) & mkgmap:exit_hint=true
  { set exit_hint = 'Exit ${mkgmap:exit_hint_ref}';
# 'Exit ${mkgmap:exit_hint_name|subst: Road=> Rd|subst: Street=> St|subst: Avenue=> Ave|subst: Mile=> Mi|subst: Boulevard=> Blvd|subst: Parkway=> Pkwy|subst: Highway=> Hwy}' |
# 'Exit ${ref|subst: South=> S|subst: North=> N|subst: East=> E|subst: West=> W}' |
# 'Exit ${mkgmap:exit_hint_ref|subst: South=> S|subst: North=> N|subst: East=> E|subst: West=> W} ${mkgmap:exit_hint_exit_to|subst: Road=> Rd|subst: Street=> St|subst: Avenue=> Ave|subst: Mile=> Mi|subst: Boulevard=> Blvd|subst: Parkway=> Pkwy|subst: Highway=> Hwy}' |
# 'Exit ${mkgmap:exit_hint_exit_to|subst: Road=> Rd|subst: Street=> St|subst: Avenue=> Ave|subst: Mile=> Mi|subst: Boulevard=> Blvd|subst: Parkway=> Pkwy|subst: Highway=> Hwy}' |
# 'Exit ${mkgmap:exit_hint_name|subst: Road=> Rd|subst: Street=> St|subst: Avenue=> Ave|subst: Mile=> Mi|subst: Boulevard=> Blvd|subst: Parkway=> Pkwy|subst: Highway=> Hwy}' |
# 'Exit ${mkgmap:exit_hint_ref|subst: South=> S|subst: North=> N|subst: East=> E|subst: West=> W}';
       }
# use destination hint and/or exit hint to build name
(highway=motorway_link | highway=trunk_link | highway=primary_link | highway=secondary_link | highway=tertiary_link) & (mkgmap:exit_hint=true | mkgmap:dest_hint=true)
  { name '${exit_hint} ${dest_hint}' | '${dest_hint}' | '${exit_hint}'}

I used different symbols to tell me which code is being executed. Since the result string contains a "~" I think it is executing '${destination:street} ~ ${destination}' which is strange, since there is no DESTINATION tag at all.

Can someone see why I am getting "Exit 18 Beck Rd ~ Beck Road" when I should be getting "Exit 18 Beck Rd"?

Attached are screenshots and actual osm.pbf data for just this intersection.
