Interpreters are proved equivalent to the reference one. Parser interpreter, we define a packrat parser interpreter as well as anĮxtension that is capable of semantic interpretation. Properties are embedded in the types of the operations so that the proofs canīe easily constructed from local proof obligations. Properties including soundness and completeness are maintained. Find 3 ways to say PACKRAT, along with antonyms, related words, and example sentences at. Syntax trees that represent the computational trace of the parser to provide anĮffective proof certificate for correct parsing and ensure that parsing Rather than relying on an inductive definition of parsing, we use abstract To ensure termination of parsing, we define a notion of a well-formed grammar. Reference implementation of a recursive parser interpreter for PEGs. We use the rich type system of the PVS specification languageĪnd verification system to formalize the metatheory of PEGs and define a
