This package provides functions to emit XML, with some complexity for handling indentation. It can be used to produce all sorts of useful XML output; it has an RSS 2.0 emitter built in, so you can make RSS feeds trivially.

This library allows creation of hash tables with arbitrary test/hash functions, in addition to the test functions allowed by the standard (EQ, EQL, EQUAL and EQUALP), even in implementations that don't support this functionality directly.

nontrivial-gray-streams is a compatibility system for Gray streams, which is an extension to Common Lisp that makes it possible to implement Common Lisp streams using generic functions.

The Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

CIEL is a ready-to-use collection of libraries providing: a binary, to run CIEL scripts; a simple full-featured REPL for the terminal; a Lisp library and a core image.

Alternative to the compiler-macro library:

• Here, we do not treat compiler notes as warnings, but instead these are a separate class of conditions. These are also not errors.

• Two main condition classes are provided: compiler-macro-notes:note and compiler-macro-notes:optimization-failure-note. While the latter is a subclass of the former, the latter notes are printed in a slightly different manner to the former.

• To be able to correctly print the expansion path that led to the condition, user code is expected to avoid performing a nonlocal exit to a place outside with-notes.

MT19937 is a portable Mersenne Twister pseudo-random number generator for Common Lisp.

string-pokemonize provides a function that alternates uppercase and lowercase characters for a given string.

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 package provides an implementation of the flexichain protocol, allowing client code to dynamically add elements to, and delete elements from a sequence (or chain) of such elements.

This package provides a grab bag of miscellaneous Common Lisp utilities.

This package provides support routines for the claw Common Lisp package.

Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to as CLIM and Iterate.

This package provides a Common Lisp environment for declarative and generative algorithmic composition.

cl-jpl-util is a collection of Common Lisp utility functions and macros, primarily for software projects written in CL by the author.

This is a Common Lisp library for reading and printing MIME content. It supports automatic conversion between 7-bit, quoted-printable and base64 encodings.

System-Load is a Common Lisp library for accessing the system's CPU and memory usage.

40ants-asdf-system provides a class for being used instead of asdf:package-inferred-system in 40ANT systems.

CAMBL is a Common Lisp library providing a convenient facility for working with commoditized values. It does not allow compound units (and so is not suited for scientific operations) but does work rather nicely for the purpose of financial calculations.

This package provides a Common Lisp system with a collection of common tests and operations to help handling pathnames. It does not actually deal in handling the accessing of files on the underlying system however.

This Common Lisp library provides a tiny utility to change the size of a simple-array ensuring that the resulting array is still a simple-array.

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.

This Common Lisp library converts strings, symbols and keywords between any of the following typographical cases: PascalCase, camelCase, snake_case, kebab-case (lisp-case).
