RT provides a framework for writing regression test suites.

NST is a unit/regression testing system for Common Lisp.

This package provides a Common Lisp testing framework system CACAU which was built to be independent of assertions systems.

Trivial-Benchmark runs a block of code many times and outputs some statistical data for it. On SBCL this includes the data from time, for all other implementations just the real-time and run-time data. However, you can extend the system by adding your own metrics to it, or even by adding additional statistical computeations.

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

This package provides support routines for the claw Common Lisp package.

This package provides a BNF parser in Common Lisp.

This library contains code that implements Common Lisp hash tables.

Bobbin is a simple word-wrapping library for strings in Common Lisp. It aims to be simple, work nicely for the majority of cases, and degrade gracefully for edge cases. It is not particularly concerned with speed — if you need very high-performance word wrapping, Bobbin is not for you.

The GRAPH Common Lisp library provides a data structures to represent graphs, as well as some graph manipulation and analysis algorithms (shortest path, maximum flow, minimum spanning tree, etc.).

This is a small library to help you with managing the Common Lisp docstrings for your library.

Coalton is a dialect of ML embedded in Common Lisp. It emphasizes practicality and interoperability with Lisp, and is intended to be a DSL that allows one to gradually make their programs safer.

This is a very short and simple program, written in Common Lisp, that extends Common Lisp to embed shell code in a manner similar to Perl's backtick. It has been forked from SHELISP.

cl-numerical-utilities is a collection of packages useful in numerical applications, each big enough to be its own package, but too small to split out into a separate ASDF system.

Portable document preparation system.

This package implements a simple interface for using WebSockets via Common Lisp.

CL-LOG is a general purpose logging utility, loosely modelled in some respects after Gary King's Log5. Its features include: logging to several destinations at once, via "messengers", each messenger is tailored to accept some log messages and reject others, and this tailoring can be changed on-the-fly, very rapid processing of messages which are rejected by all messengers, fully independent use of the utility by several different sub-systems in an application, support for messengers which cl:format text to a stream, support for messengers which do not invoke cl:format, timestamps in theory accurate to internal-time-units-per-second.

This is a library for access to atomic operation primitives such as compare-and-swap. It aims to be a rather thin layer over what the implementations offer.

This library provides modern file handling for Common Lisp, which avoids many of the pitfalls of pathnames.

This is an implementation of the "Markless standard" (https://github.com/shirakumo/markless) at version 1.0. It handles the parsing of plaintext from a stream into an abstract syntax tree composed out of strings and component objects. From there the AST can be easily compiled into a target markup language like HTML.

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 a Common Lisp library to convert geographic coordinates between latitude/longitude and Maidenhead locator system.

The LOCAL-TIME library is a Common Lisp library for the manipulation of dates and times. It is based almost entirely upon Erik Naggum's paper "The Long Painful History of Time".

This Common Lisp library provides macros to access foreign memory.
