[mkgmap-dev] Need help with string handling in mkgmap

Fri Feb 16 11:38:03 GMT 2018

Hi all

after playing a little bit with the syntax of "conf" and "subst" i 
finally found a solution, which suits for my needs :

power=generator & generator:source=wind
     { name '${manufacturer} (${ref},${height|subst:"m=>"} m)' | 
'${manufacturer} (${ref})' |
     '${manufacturer} (${height|subst:"m=>"} m)' | '${manufacturer}' | 
'${ref}' | '${height|subst:"m=>"} m' }
                   [0x5912 level 2]

A sentence like this works for me, thanks for your hints
