Python ParseRuleSet Examples

Example #1

 def parse(self, lcls, head, tokens, output):
     grammar = ParseRuleSet()
     for rule_name, rule in sorted(lcls.items(), reverse=True):
         if isinstance(rule, ParseRule):
             grammar.add(rule)
     logging_builder = LoggingBuilder(lcls)
     parse(grammar, head, tokens).apply(logging_builder)
     print(logging_builder.get_text())
     logging_builder.compare(output, self)

Example #2

 def parse(self, lcls, head, tokens, output):
     grammar = ParseRuleSet()
     for rule_name, rule in sorted(lcls.items(), reverse=True):
         if isinstance(rule, ParseRule):
             grammar.add(rule)
     logging_builder = LoggingBuilder(lcls)
     parse(grammar, head, tokens).apply(logging_builder)
     print(logging_builder.get_text())
     logging_builder.compare(output, self)
