[mkgmap-dev] Bug in subst

Wed May 28 07:45:51 BST 2014

Hi, 

Is this the best way to make bug reports? I couldn't find a 'trac' for
mkgmap... 

Using r3230, if I have the following in a style file: 

name=* & highway=* {set name='${name|subst:^(Doctor|Dokter) ~>Dr }'} 

then mkgmap crashes while loading the style files. After doing various
tests my conclusion is that it is triggered by the "|" in the pattern. I
tried escaping it with a backslash but it didn't change anything. 

I have found a kind-of workaround, by making the alternatives into
separate calls to subst, but that will result in enormously long
commands in the real use I have in mind. The example above is
deliberately short to illustrate the bug. 

The stack trace is: 

java.lang.IllegalStateException: No match found
