fast-http is a HTTP request/response protocol parser for Common Lisp.

When dealing with network protocols and file formats, it's common to have to read or write 16-, 32-, or 64-bit datatypes in signed or unsigned flavors. Common Lisp sort of supports this by specifying :element-type for streams, but that facility is underspecified and there's nothing similar for read/write from octet vectors. What most people wind up doing is rolling their own small facility for their particular needs and calling it a day.

This library attempts to be comprehensive and centralize such facilities. Functions to read 16-, 32-, and 64-bit quantities from octet vectors in signed or unsigned flavors are provided; these functions are also SETFable. Since it's sometimes desirable to read/write directly from streams, functions for doing so are also provided. On some implementations, reading/writing IEEE singles/doubles (i.e. single-float and double-float) will also be supported.

cl-docutils is a Common Lisp implementation of the Docutils text processing system for processing plaintext into presentational formats such as HTML and LaTeX. It is based upon the Python Docutils reference implementation but uses Common Lisp idioms making it easier to extend and more flexible. As with the reference implementation it includes a parser for the reStructured text plaintext markup syntax which is suitable for marking up documentation and for use as user markup for collaborative web sites. It is successfully used to support a higher education peer-review assessment and online tutorial system.

cl-smug is a library for parsing text, based on monadic parser combinators. Using a simple technique from the functional programming camp, cl-smug makes it simple to create quick extensible recursive descent parsers without funky syntax or impenetrable macrology.

Chunga implements streams capable of chunked encoding on demand as defined in RFC 2616.

This Common Lisp library implements a parser generator for the ABNF grammar format as described in RFC2234. The generated parser is a regular expression scanner provided by the cl-ppcre lib, which means that we can't parse recursive grammar definition. One such definition is the ABNF definition as given by the RFC. Fortunately, as you have this lib, you most probably don't need to generate another parser to handle that particular ABNF grammar.

cl-morse is a Morse code translation library for Common Lisp.

This is a Common Lisp library to calculate std140 or std430 layouts for a glsl UBO/SSBO.

This package provides a Common Lisp templating system based on Python Django with a syntax similar to Python Jinja2.

cl-mysql is a Common Lisp implementation of a MySQL wrapper.

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.

Defstar is a collection of Common Lisp macros that can be used in place of defun, defmethod, defgeneric, defvar, defparameter, flet, labels, let* and lambda. Each macro has the same name as the form it replaces, with a star added at the end, e.g. defun. (the exception is the let* replacement, which is called *let).

Dynamic-Classes helps to ease the prototyping process by bringing dynamism to class definition.

This package provides a PEM (Privacy-Enhanced Mail) parser for Common Lisp.

This Common Lisp library provides reader macros for concise expression of function partial application and composition.

This collection of utilities is useful in contexts where you want a macro that uses lambda-lists in some fashion but need more precise processing.

This library implements the let+ macro, which is a dectructuring extension of let*. It features:

• Clean, consistent syntax and small implementation (less than 300 LOC, not counting tests)

• Placeholder macros allow editor hints and syntax highlighting

• &ign for ignored values (in forms where that makes sense)

• Very easy to extend

This is a Common Lisp library to make histograms using UTF-8 block characters.

This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.

Triads is a simple command line tool that reads roman numeral notation from standard input (or a file) and an musical key and outputs the roman numeral in addition to the notes of the triad associated with that roman numeral given in the key.

This Common Lisp library provides a fast reader for data in LibSVM format.

Clamp is an attempt to bring the powerful, but verbose, language of Common Lisp up to the terseness of Arc.

There are two parts to Clamp. There is the core of Clamp, which implements the utilities of Arc that are easily converted from Arc to Common Lisp. The other part is the "experimental" part. It contains features of Arc that are not so easy to copy (ssyntax, argument destructuring, etc.).

Xmls is a self-contained, easily embedded parser that recognizes a useful subset of the XML spec. It provides a simple mapping from XML to Lisp structures or s-expressions and back.

Enchant is a Common Lisp interface for the Enchant spell-checker library. The Enchant library is a generic spell-checker library which uses other spell-checkers transparently as back-end. The library supports the multiple checkers, including Aspell and Hunspell.
