The Lemon Parser Generator

## NAME

**lemon** – The Lemon Parser Generator

## SYNOPSIS

**lemon** \[**-bcgmqsx**\] *input*

## DESCRIPTION

**lemon** is an LALR(1) parser generator for C or C++. It does the same job as bison and yacc. But  **lemon** is not another bison or yacc clone. It uses a different grammar syntax which is designed to reduce the number of coding errors. **lemon** also uses a more sophisticated parsing engine that is faster than yacc and bison and which is both reentrant and thread-safe. Furthermore,  **lemon** implements features that can be used to eliminate resource leaks, making is suitable for use in long-running programs such as graphical user interfaces or embedded controllers.

**lemon** will read the grammer from *input* and write out a parser for that grammar in the C language.
