Hi Joey, Yes, precedence does matter. (to answer your subject first)
In fact, if you have an alternative between a parser that is easy to satisfy (integer, say with the string '13') and a parser that is more demanding (decimal, consuming '.2432' as well), the order does matter a lot. Parslet (PEG parsers) will try alternatives from left to right strictly, without magic. Once something can be matched, the alternative is considered matched. In your case, that would mean that the :number-rule always matches the integer prefix of any decimal. No decimal can ever be matched with your parser. And finally: If that is on the website now, I am sure the input given is always integer ;) Because it has never worked. It is a bug in documentation (the worst kind of bugs). Would you care to correct it and send me a patch? regards, kaspar
