Re: [mkgmap-dev] [Patch v1] check length in substring style function

Hi Gerd

I forgot to answer this post from gbbickerton: "May i suggest that a test is made to check that the string is long enough before applying this filter otherwise an exception occurs .It would be unsafe to use this filter in any style without such a test. "

Well remembered, thanks. It could also do with some tests, I've attached some. I would like to use SyntaxException instead of ExitException for all cases where an error can be detected at compile time in a style file. I realise that ExitException was already used in that class. PartFilter is the only other example I can see where it does not use SyntaxException. ..Steve
