Re: [mkgmap-dev] Substring returns full string

Hi Gerd

In ValueBuilder

we receive the string " substring:1:14" (with the leading blank) and that is not removed, so we don't match

OK, so this works if you quote the argument: '${rcnname | substring:"1:14"}' but not with the old syntax. The attached patch fixes this and I think it is safe against breaking existing styles. If it does break old styles, then it will have to be un-applied - in general the old syntax is ambiguous. I've added an error check for when an unknown filter is seen, which should make it obvious when something like this happens. ..Steve
