This collection of utilities is useful in contexts where you want a macro that uses lambda-lists in some fashion but need more precise processing.

zsort is a collection of portable sorting algorithms. Common Lisp provides the sort and stable-sort functions but these can have different algorithms implemented according to each implementation. Also, the standard sorting functions might not be the best for a certain situations. This library aims to provide developers with more options.

This library builds on the venerable idea of dynamically memoizing functions. A memoized function remembers results from previous computations and returns cached results when called again with the same arguments rather than repeating the computation.

cl-tar is a Common Lisp library providing a high-level interface for interacting with tar archives.

This package provides a noise library for Common Lisp.

This package provides a CONSPACK implementation for Common Lisp.

Trucler defines a CLOS-based protocol to be used by Common Lisp compilers for environment query and update. In addition, library authors can use the trucler-native interface to inspect native environments. Trucler supports introspection for variables, functions, tags, blocks and optimization policies.

cl-inotify uses cl-cffi to provide a Common Lisp interface to the Linux inotify API.

Eazy-Gnuplot is a Common Lisp interface to gnuplot which eschews CFFI, CLOS and structures. It communicates with gnuplot via *standard-output*, and users can plot data by printing to that stream.

A simple templating library loosely based on BRL (the Beautiful Report Language). It leverages the power of the lisp reader to create a dynamic templating system that is easy to understand and powerful enough for most applications.

This is a library for selecting portions of sequences, arrays or data-frames.

This library can be used to print the licenses used by a Common Lisp project and its dependencies.

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

iterate is an iteration construct for Common Lisp. It is similar to the CL:LOOP macro, with these distinguishing marks:

• it is extensible,

• it helps editors like Emacs indent iterate forms by having a more lisp-like syntax, and

• it isn't part of the ANSI standard for Common Lisp.

VAS-STRING-METRICS provides the Jaro, Jaro-Winkler, Soerensen-Dice, Levenshtein, and normalized Levenshtein string distance/similarity metrics algorithms.

CL-HTTPS-EVERYWHERE parses HTTPS Everywhere rulesets and makes them available for use in Lisp programs.

This library implements a basic promise datastructure, which is useful for dealing with asynchronous behaviours. Importantly, this library does not use any other libraries or frameworks, and instead leaves the execution and state transition of promise objects in your control, making it easy to integrate.

The Plump-SEXP library is a backend for Plump which can convert between S-expressions and the Plump DOM.

This package provides Common Lisp support for reading the Terragen .TER format. The format specification can be found at https://planetside.co.uk/wiki/index.php?title=Terragen_.TER_Format

This is a Common Lisp library to read and write disk-based file archives such as those generated by the tar and cpio programs on Unix.

This Common Lisp package offers functions for parsing and formatting decimal numbers. The package's main interface are the functions parse-decimal-number and format-decimal-number. The former is for parsing strings for decimal numbers and the latter for pretty-printing them as strings.

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 package provides CFFI bindings for the stb_vorbis audio library to Common Lisp.

This library provides a simple multithreading worker mechanism.
