Yacc operates the other way around, with the parser calling the tokenizer. The Lemon approach is reentrant and threadsafe, whereas Yacc uses global variables and is therefore neither. Reentrancy is especially |

Lemon has benefited from this effect. Over the years, the Lemon parser generator has been extended and enhanced to provide new capabilities and improved performance to SQLite. A few of the specific enhancements to Lemon that are specifically designed for use by SQLite include: |
