Abstract
Parsing Expression Grammar (PEG) proposed by Ford has the higher expressive ability than traditional Backus–Naur form, but it also has problems such as prefix capture. “Prefix capture” is a problem of hiding the language to be accepted according to the order of choice. To support checking syntax files including such mistakes, this paper proposes Tamias: a production rules checker to support checking the PEG syntax files. Tamias has PEG interpreter which can check production rules of PEG. It can verify the behavior of production rules and measure the reach rate of choices.
