This is a simple library to retrieve the argument list of a function.

This is a Common lisp library to unify access to the most common dictionary-like data structures.

trivial-garbage provides a portable API to finalizers, weak hash-tables and weak pointers on all major implementations of the Common Lisp programming language.

Common Lisp port of Universal Tween Engine.

Maiden is a collection of systems to help you build applications and libraries that interact with chat servers. It can help you build a chat bot, or a general chat client. It also offers a variety of parts that should make it much easier to write a client for a new chat protocol.

This package provides GNU gettext completely implemented in Common Lisp without any C library bindings.

This is a reverse proxy server written in and configurable in Common Lisp. It supports WebSocket, HTTP, HTTPS, HTTP to HTTPS redirecting, port and host forwarding configuration using a real programming language, HTTP header and body manipulation (also using a real programming language).

This is a small Common Lisp library to make slugs, mainly for URIs, from English and beyond.

cl-num-utils implements simple numerical functions for Common Lisp, including:

• num=, a comparison operator for floats

• simple arithmeric functions, like sum and l2norm

• elementwise operations for arrays

• intervals

• special matrices and shorthand for their input

• sample statistics

• Chebyshev polynomials

• univariate rootfinding

Serapeum is a conservative library of Common Lisp utilities. It is a supplement, not a competitor, to Alexandria.

McCLIM is an implementation of the Common Lisp Interface Manager specification, a toolkit for writing GUIs in Common Lisp.

3D-VECTORS is a library for vector math in 3D space. It contains most of the vector operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable.

Salza2 is a Common Lisp library for creating compressed data in the zlib, deflate, or gzip data formats, described in RFC 1950, RFC 1951, and RFC 1952, respectively.

PRINTV is a "batteries-included" tracing and debug-logging macro for Common Lisp.

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.

DIFF is a package for computing various forms of differences between blobs of data and then doing neat things with those differences. Currently diff knows how to compute three common forms of differences: "unified" format diffs, "context" format diffs, and "vdelta" format binary diffs.

This Common Lisp library provides bindings for the ZeroMQ lightweight messaging kernel.

data-format-validation is a library for Common Lisp providing a consistent regular interface for converting (and validating) external data (in the form of strings usually) into internal data types and for formatting internal data back into external presentable strings, all according to a conversion or type specification.

This is a Common Lisp library to present tabular data in ascii-art tables.

This package provides a common lisp CFFI wrapper for the SciPy version of Cephes special functions.

MODULARIZE is an attempt at providing a common interface to segregate major application components. This is achieved by adding special treatment to packages. Each module is a package that is specially registered, which allows it to interact and co-exist with other modules in better ways. For instance, by adding module definition options you can introduce mechanisms to tie modules together in functionality, hook into each other and so on.

This library validates superclasses according to a simple substitution model, thereby greatly simplifying the definition of class mixins.

On Cliki.net <http://www.cliki.net/Common%20Lisp%20Utilities>, there is a collection of Common Lisp Utilities, things that everybody writes since they're not part of the official standard. There are some very useful things there; the only problems are that they aren't implemented as well as you'd like (some aren't implemented at all) and they aren't conveniently packaged and maintained. It takes quite a bit of work to carefully implement utilities for common use, commented and documented, with error checking placed everywhere some dumb user might make a mistake.

This package provides a Common Lisp implementation of Base64 encoding and decoding. Base64 encoding is a technique to encode binary data in a portable, safe printable, 7-bit ASCII format.
