Cluffer is a library for representing the buffer of a text editor. As such, it defines a set of CLOS protocols for client code to interact with the buffer contents in various ways, and it supplies different implementations of those protocols for different purposes.

THE-COST-OF-NOTHING is a library for measuring the run time of Common Lisp code. It provides macros and functions for accurate benchmarking and lightweight monitoring. Furthermore, it provides predefined benchmarks to determine the cost of certain actions on a given platform and implementation.

This package provides a way of extracting and replicating the compile-time side-effects of forms.

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

one-more-re-nightmare is a regular expression engine that uses the technique presented in Regular-expression derivatives re-examined (Owens, Reppy and Turon, 2009; doi:10.1017/S0956796808007090) to interpret and compile regular expressions.

Common Lisp ships with a set of powerful built in data structures including the venerable list, full featured arrays, and hash-tables. CL-containers enhances and builds on these structures by adding containers that are not available in native Lisp (for example: binary search trees, red-black trees, sparse arrays and so on), and by providing a standard interface so that they are simpler to use and so that changing design decisions becomes significantly easier.

Provides a simple way of directing output to a stream according to the concise and intuitive semantics of FORMAT's stream argument.

MAP-BIND is a macro that allows visual grouping of variables with their corresponding values in calls to mapping operators when using an inline LAMBDA.

The Babel library solves a similar problem while understanding more encodings. Trivial UTF-8 was written before Babel existed, but for new projects you might be better off going with Babel. The one plus that Trivial UTF-8 has is that it doesn't depend on any other libraries.

Chemboy is a Common Lisp program for doing basic chemistry calculations. This package provides the text-based interface for Chemboy.

This is a utility kit for functionality related to OpenGL. It provides the following:

• kit.glm: This re-exports sb-cga and mathkit for convenience.

• kit.gl.shader: This provides shader dictionary and compilation functionality similar to what was originally found in sdl2kit.

• kit.gl.vao: This provides an interface for Vertex Array Objects.

MAGICFFI is a Common Lisp CFFI interface to libmagic(3), the file type determination library using magic numbers.

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.

Closer to MOP is a compatibility layer that rectifies many of the absent or incorrect CLOS MOP features across a broad range of Common Lisp implementations.

This is a small Common Lisp library that finds an open port within a range.

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

This is a purely math-related utility kit, providing functions which can be useful for games, 3D, and GL in general.

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

Inquisitor is a cross-implementation library providing encoding/end-of-line detection and external-format abstraction for Common Lisp.

This package provides functions for generating lorem ipsum text.

This package provides CFFI bindings for Common Lisp to the Cairo C library.

Retrospectiff is a common lisp library for reading and writing images in the TIFF (Tagged Image File Format) format.

Calispel is a Common Lisp library for thread-safe message-passing channels, in the style of the occam programming language, also known as communicating sequential processes (CSP). See https://en.wikipedia.org/wiki/Communicating_sequential_processes.

Calispel channels let one thread communicate with another, facilitating unidirectional communication of any Lisp object. Channels may be unbuffered, where a sender waits for a receiver (or vice versa) before either operation can continue, or channels may be buffered with flexible policy options.

Because sending and receiving on a channel may block, either operation can time out after a specified amount of time.

A syntax for alternation is provided (like ALT in occam, or Unix select()): given a sequence of operations, any or all of which may block, alternation selects the first operation that doesn't block and executes associated code. Alternation can also time out, executing an "otherwise" clause if no operation becomes available within a set amount of time.

Calispel is a message-passing library, and as such leaves the role of threading abstractions and utilities left to be filled by complementary libraries such as Bordeaux-Threads and Eager Future.
