CF is a Common Lisp library for doing computations using continued fractions.

An implementation of Relax NG schema validation written in Common Lisp, including support for compact syntax, DTD Compatibility, and the XSD type library.

This is a bare-bones Permuted Congruential Generator implementation in pure Common Lisp.

This project is meant to provide tools for internationalizing Common Lisp programs.

One important aspect of internationalization is of course the language used in error messages, documentation strings, etc. But with this project we provide tools for all other aspects of internationalization as well, including dates, weight, temperature, names of physical quantities, etc.

This is a library to abstract away the parsing of Unix-style command-line arguments. Use it in conjunction with asdf:program-op or cl-launch for portable processing of command-line arguments.

CL-PUNCH is a Scala-like anonymous lambda literal.

CMN provides a package of functions to hierarchically describe a musical score. When evaluated, the musical score is rendered to an image.

trivial-clipboard gives access to the system clipboard.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

cl-random is a library for generating random draws from various commonly used distributions, and for calculating statistical functions, such as density, distribution and quantiles for these distributions.

ISSR core provides functions and variables for ISSR server modules so that different servers can behave similarly. The most important features are Document Object Model differencing to generate instructions to update a DOM, and DOM cleaning, to ensure that all remote DOMs are the same.

This is a portable Universal Resource Identifier library for Common Lisp programs. It parses URI according to the RFC 2396 specification.

This piece of code sets up some reader macros that make it simpler to input string literals which contain backslashes and double quotes This is very useful for writing complicated docstrings and, as it turns out, writing code that contains string literals that contain code themselves.

Parseq (pronounced parsec) is a parsing library for common lisp. It can be used for parsing lisp's sequences types: strings, vectors (e.g. binary data) and lists. Furthermore, parseq is able to parse nested structures such as trees (e.g. lists of lists, lists of vectors, vectors of strings).

Parseq uses parsing expression grammars (PEG) that can be defined through a simple interface. Extensions to the standard parsing expressions are available. Parsing expressions can be parameterised and made context aware. Additionally, the definition of each parsing expression allows the arbitrary transformation of the parsing tree.

The library is inspired by Esrap and uses a very similar interface. No code is shared between the two projects, however. The features of Esrap are are mostly included in parseq and complemented with additional, orthogonal features. Any resemblance to esrap-liquid is merely coincidental.

This package provides Common Lisp extension to the MOP to allow abstract, final and singleton classes.

A small collection of common lisp macros to make collecting values easier.

A dataflow extension to Common Lisp that maintains a consistent state of cells according to functions specifying their relation.

dbi is a Common Lisp library providing a database independent interface for MySQL, PostgreSQL and SQLite.

LLA is a high-level Common Lisp library built on BLAS and LAPACK, but providing a much more abstract interface with the purpose of freeing the user from low-level concerns and reducing the number of bugs in numerical code.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.

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

This is a Common Lisp wrapper for libjpeg-turbo library which provides TurboJPEG API for compressing and decompressing JPEG images.

This is a simple queue library for Common Lisp with features such as non-consing thread safe queues and fibonacci priority queues.

This is a common lisp library to easily pluralize and singularize English and Portuguese words. This is a port of the ruby ActiveSupport Inflector module.
