With the following code, depending on parboiled 2.1.0, I get a null pointer exception trying to create my parser:
import org.parboiled2._
class MyParser(val input: ParserInput) extends Parser {
val number = rule { oneOrMore("0" - "9") }
}
object MyParser {
def main(args: Array[String]) {
val parser = new MyParser("111") // null pointer here
parser.number.run() match {
case _ => print("woot")
}
}
}
The following exception is thrown running the main method:
Exception in thread "main" java.lang.NullPointerException
at org.parboiled2.Parser.__saveState(Parser.scala:252)
at com.fitbit.perf_sampler.parser.StackParser.<init>(StackParser.scala:11)
at com.fitbit.perf_sampler.parser.RunMe$.main(StackParser.scala:25)
at com.fitbit.perf_sampler.parser.RunMe.main(StackParser.scala)
Specifically in the line below valueStack is null.
def __saveState: Mark = new Mark((_cursor.toLong << 32) + (_cursorChar.toLong << 16) + valueStack.size)
It seems likely that the examples are out of date, but I haven't been able to find anything that corresponds with 2.1 -- any pointers?
