WebbRecursive Descent Parsers An early implementation of top-down (LL(1)) parsing was recursive descent. A parser was organized as a set of parsing procedures, one for each non-terminal. Each parsing procedure was responsible for parsing a sequence of tokens derivable from its non-terminal. For example, a parsing procedure, A, when called, would ... Webb23 jan. 2024 · Coming to LR parsing we have 3 main types: Simple LR or SLR (1) – Can parse a superset of LR (0) grammars but a proper subset of LR (1) grammars. LALR – Can parse a superset of grammars that can be parsed by SLR (1) parsers but a proper subset of LR (1) grammars. LR (1) or Canonical LR (1) – Can parse any LR (1) grammar.
