Text processing software - string splitters, parsers, and so on

Regular expression libraries: (main topic: regular expression)

  • cl-irregsexp - A fast regular expression library with a lispy alternative to traditional syntax for text matching
  • cl-ppcre - A portable, Perl-compatible regular expression library by Edi Weitz
  • cl-string-match - Provides substring (subsequence) search and text processing algorithms implementations including regular expression, prefix/suffix tree data structures, etc
  • lol-re - Tiny wrapper around CL-PPCRE, inspired by #~M and #~S read-macro from Let Over Lambda, making use of regular expressions more perly
  • pregexp - Portable Regular Expressions for Scheme and Common Lisp
  • re - The re package is a small, portable, lightweight, and quick, regular expression library for Common Lisp
  • recursive-regex - A library to extend CL-PPCRE to make regular expression named capture groups dispatch to custom matcher functions and named-expression patterns
  • Regex - Regex is a full-featured regular expression compiler and matching engine written by Michael Parker
  • regex (library by asciian) - A relatively incomplete (as of Jan 2018) relatively concise backtracking POSIX compatible regular expression library
  • terse-ppcre - TERSE-PPCRE aims to make manipulating CL-PPCRE regular expression parse trees easier and more succinct
  • The Regex Coach - A graphical Common Lisp application which can be used to experiment with (Perl-compatible) regular expressions interactively

Parser generators: (main topic: parser generator)

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
  • 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
  • token-stream - Lexer class for cl-stream
  • Zebu - A Tool for Specifying Reversible LALR(1) Parsers

String processing: (main topic: string)

  • charseq - This package provides charseq structure which represents an efficient character sequence
  • cl-change-case - cl-change-case is a library to convert strings between camelCase, param-case, snake_case and more
  • cl-cidr-notation - cl-cidr-notation is a library for converting IP addresses and CIDR blocks from integer to string representations and vice versa
  • cl-interpol - CL-INTERPOL modifies the reader so that you can have interpolation of strings similar to Perl or Unix Shell scripts
  • cl-string-complete - A small library for string completion by Robert Smith
  • cl-string-match - Provides substring (subsequence) search and text processing algorithms implementations including regular expression, prefix/suffix tree data structures, etc
  • cl-strings - cl-strings is a portable, dependency-free set of utilities to manipulate strings in Common Lisp (split, join, replace, insert, clean, change case,…)
  • Levenshtein - The Levenshtein Distance algorithm finds the minimum number of operations needed to transform one string into the other, where an operation is an insertion, deletion, or substitution of a single character
  • lispbuilder-clawk - Stub added for asdf-install see Lispbuilder site for more details
  • lispbuilder-lexer - Stub added for asdf-install see Lispbuilder site for more details
  • lispbuilder-regex - Stub added for asdf-install see Lispbuilder site for more details
  • mk-string-metrics - This library implements efficient algorithms that calculate various string metrics in Common Lisp:
  • parse-float - A function to parse floating-point values from a string in Common Lisp
  • str - str is a modern and consistent string manipulation library (split, join, concat, replace, blank-p,…) to install with (ql:quickload :str)

Text: (main topic: text)

Streams: (main topic: stream) can be useful for, but are not limited to text processing.

  • CAPTURED-STREAM - captured-stream is a small Common Lisp library for viewing streams as sequences
  • changed-stream - Is a lisp library for non-destructive changing of streams by inserting or deleting characters at a position
  • Chunga - Chunga is a web/networking library which implements portable chunked HTTP streams as described in RFC 2616
  • cl-binary-file - The binary file package contains utilities to read and write binary files
  • CL-PLUS-SSL - This library is a fork of SSL-CMUCL
  • Cyclosis - Cyclosis is a combined implementation of the functionality of the Common Lisp stream dictionary and that of the Gray streams proposal
  • deflate - Deflate by Pierre Mai is a Common Lisp implementation of Deflate (RFC 1951) decompression, with optional support for ZLIB-style (RFC 1950) and gzip-style (RFC 1952) wrappers of deflate streams
  • fast-io - Fast-io is about improving performance to octet-vectors and octet streams (though primarily the former, while wrapping the latter)
  • Gray streams - "Gray Streams" are a generic function wrapping of the COMMON-LISP streams in the standard library, allowing for further specialization by end users
  • gzip-stream - gzip-stream is a simple wrapper around salza which gives CL users gzip compression and decompression in the form of streams (gzip-input-stream and gzip-output-stream)
  • MIME4CL - MIME4CL allows you to craft MIME compliant messages or to parse and handle them programmatically
  • pretty-function - pretty-function provides an API for making individual functions pprint differently when written to an output stream
  • rfc2388 - rfc2388 processes HTTP POST form data using enctype "multipart/form-data", as described in RFC 2388
  • simple-stream - Simple-streams are Franz's proposal for a Gray-streams replacement
  • trivial-bit-streams - Trivial-bit-streams implements flexible buffered bit streams
  • trivial-gray-streams - trivial-gray-streams provides an extremely thin compatibility layer for Gray streams
