[mkgmap-dev] How do I transform the name of all Ways?

Hi everyone, I want to do some transformations on the names of all the Ways, is there a standard way to do that? For example, I want to replace all occurrences of "Avenida" for "Av.". I tried adding this to my lines file: |highway=* & name ~ '(?i)avenida\s+.*' { add streettype:movedend='${name|subst:(?i)avenida\s+~>}, Av.'} #| But There was no effect. Thanks in advance, Alexandre
