Error Reporting in Parsing Expression Grammars
[article]
2016
arXiv
pre-print
Parsing Expression Grammars (PEGs) describe top-down parsers. Unfortunately, the error-reporting techniques used in conventional top-down parsers do not directly apply to parsers based on Parsing Expression Grammars (PEGs), so they have to be somehow simulated. While the PEG formalism has no account of semantic actions, actual PEG implementations add them, and we show how to simulate an error-reporting heuristic through these semantic actions. We also propose a complementary error reporting
