Trivial-features ensures that *FEATURES* is consistent across multiple Common Lisp implementations.

DAEMON provides the functionality of daemonizing Common Lisp processes on UNIX like platforms.

Feeder is a syndication feed library. It presents a general protocol for representation of feed items, as well as a framework to translate these objects from and to external formats. It also implements the RSS 2.0 and Atom formats within this framework.

This library is a collection of functions and macros for manipulating Common Lisp arrays and performing numerical calculations with them.

Optima is a fast pattern matching library which uses optimizing techniques widely used in the functional programming world.

DEFPACKAGE-PLUS is an extensible DEFPACKAGE variant with predictable cross-platform behavior and some utilities useful for versioning.

This library provides almost the same code as used inside Quicklisp for drawning progress bars

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

This package provides a Common Lisp translation library similar to CL-I18N and CL-L10N.

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

For is a library for an extensible iteration macro. It allows you to write concise looping constructs similar to loop and iterate. Unlike loop however it is extensible and sensible, and unlike iterate it does not require code-walking and is easier to extend.

This package provides a Common Lisp system helping in scripting, it uses uiop:run-program as a backend.

This package provides a SDL2 based vector graphic library for Common Lisp.

This library provides a wrapper type for secret values, to reduce the risk of accidentally revealing them.

This is a Common Lisp library providing lambda shorthand macros aiming to be used in cases where the word lambda and the arguments are longer than the body of the lambda.

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

This package provides a collection of types, functions and macros. Some of the functionality is implemented from Graham's On Lisp and Seibel's Practical Common Lisp.

This library allows for cooperative multitasking with help of cl-cont for continuations. It tries to mimic the API of bordeaux-threads as much as possible.

This package provides highly optimized base64 encoding and decoding. Besides conversion to and from strings, integer conversions are supported. Encoding with Uniform Resource Identifiers is supported by using a modified encoding table that uses only URI-compatible characters.

This library provides a modern project skeleton generator. In contract with other generators, CL-Project generates one package per file and encourages unit testing by generating a system for unit testing, so you can begin writing unit tests as soon as the project is generated.

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

This package defines a Common Lisp package, :elements, with an ELEMENT structure and a number of functions to search the periodic table.

Binary-types is a Common Lisp package for reading and writing binary files. Binary-types provides macros that are used to declare the mapping between Lisp objects and some binary (i.e. octet-based) representation.

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.
