• CL-Yacc - CL-Yacc is a LALR(1) parser generator for Common Lisp, somewhat like Zebu or LALR
• com.nklein.parser-generator - com nklein parser-generator is a parser generator will generate SAX-based XML parsers for Lisp or Objective-C and create all of the necessary data types for your internal structures based on your input file
• de.setf.atn-parser - de setf atn-parser is an atn-based BNF -> Common Lisp LR(*) parser generator

• metapeg - Metapeg is a PEG parser generator created by John Leuner
• monkeylib-parser - monkeylib-parser is a parser generator loosely based on Henry Baker's META paper
• parser-combinators - An implementation of parser combinators, an alternative to parser generators
• yid - yid (Yacc Is Dead) is a parser generator based on Brzozowski's derivative from regular expressions to context-free grammars
• Zebu - Zebu is a LALR(1) parser generator similar to YACC, but for Common Lisp

Lexers: (main topic: lexer)

• cl-lex - cl-lex is a set of Common Lisp macros for generating lexical analyzers automatically
• DEFLEXER - The LEXER package implements a lexical-analyzer-generator called DEFLEXER, which is built on top of both REGEX and CLAWK
• dso-lex - dso-lex allows lexers to be defined using regular expressions a la cl-ppcre
• graylex - graylex offers a means to do string operations on input streams without slurping all input at once by using Common Lisp Gray Streams, fixed-sized and flexible buffers

• vana-inflector - A common lisp library to easily pluralize and singularize English words
• vas-string-metrics - vas-string-metrics provides the Jaro, Jaro-Winkler, Levenshtein, and normalized Levenshtein string distance/similarity metrics algorithms for text analysis

Misc:

• Francis Leboutte's functions to compute frequencies of characters, digrams and trigrams from a text file (function names and comments in French - some comments in English).
