Lemon is a parser generator, maintained as part of the SQLite project, that generates a look-ahead LR parser (LALR parser) in the programming language C from an input context-free grammar. The generator is quite simple, implemented in one C source file with another file used as a template for output. Lexical analysis is performed externally.
However, parser generators for context-free grammars often support the ability for user-written code to introduce limited amounts of context-sensitivity. (For example, upon encountering a variable declaration, user-written code could save the name and type of the variable into an external data structure, so that these could be checked against ...

Dwayne Richard Hipp (born April 9, 1961) is an American software developer and the primary author of SQLite as well as the Fossil SCM. [1] [2] He also authored the Lemon parser generator, and CVSTrac; the latter became the inspiration for Trac.
The main goal of re2c is generating fast lexers: [1] at least as fast as reasonably optimized C lexers coded by hand. Instead of using traditional table-driven approach, re2c encodes the generated finite state machine directly in the form of conditional jumps and comparisons.
A parser is a software component that takes input data (typically text) and builds a data structure – often some kind of parse tree, abstract syntax tree or other hierarchical structure, giving a structural representation of the input while checking for correct syntax. The parsing may be preceded or followed by other steps, or these may be ...
Depending upon the type of parser that should be generated, these routines may construct a parse tree (or abstract syntax tree), or generate executable code directly. One of the earliest (1964), surprisingly powerful, versions of compiler-compilers is META II , which accepted an analytical grammar with output facilities that produce stack ...
