This package implements binary trees of various kinds, presenting a uniform interface to them all.

CLAWK is an AWK implementation embedded into Common Lisp.

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

CL-FAD (for "Files and Directories") is a thin layer atop Common Lisp's standard pathname functions. It is intended to provide some unification between current CL implementations on Windows, OS X, Linux, and Unix. Most of the code was written by Peter Seibel for his book Practical Common Lisp.

This is an implementation of the Unicode Standards Annex #14 (http://www.unicode.org/reports/tr14/) line breaking algorithm. It provides a fast and convenient way to determine line breaking opportunities in text.

Note that this algorithm does not support break opportunities that require morphological analysis. In order to handle such cases, please consult a system that provides this kind of capability, such as a hyphenation algorithm.

Also note that this system is completely unaware of layouting decisions. Any kind of layouting decisions, such as which breaks to pick, how to space between words, how to handle bidirectionality, and what to do in emergency situations when there are no breaks on an overfull line are left up to the user.

ALEXA is a tool similar to lex or flex for generating lexical analyzers. Unlike tools like lex, however, ALEXA defines a domain-specific language within your Lisp program, so you don't need to invoke a separate tool.

Random-Sample is a library for reliably taking a random sample from a sequence.

This library is a portable compatibility layer around package local nicknames (PLN). This was done so there is a portability library for the PLN API not included in DEFPACKAGE.

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 library implements special functions and has a focus on high accuracy double-float calculations using the latest algorithms.

The variates package provides portable random number generation as well as numerous distributions.

This library contains a collection of machine learning algorithms for online linear classification written in Common Lisp.

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.

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.

cl-jpl-util is a collection of Common Lisp utility functions and macros, primarily for software projects written in CL by the author.

Gray streams is an interface proposed for inclusion with ANSI CL by David N. Gray. The proposal did not make it into ANSI CL, but most popular CL implementations implement it. This package provides an extremely thin compatibility layer for gray streams.

Various ASDF extensions such as attached test and documentation system, explicit development support, etc.

This an implementation of CDR 2: generic hash tables for Common Lisp

CL-octet-streams is a library implementing in-memory octet streams for Common Lisp. It was inspired by the trivial-octet-streams and cl-plumbing libraries.

bt-semaphore is a semaphore implementation for use with bordeaux-threads.

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

cl-smug is a library for parsing text, based on monadic parser combinators. Using a simple technique from the functional programming camp, cl-smug makes it simple to create quick extensible recursive descent parsers without funky syntax or impenetrable macrology.

CL-MOUNT-INFO is a Common Lisp wrapper around getmntent(3) and related C functions to get information about the mounted file system.

FLOW is a flowchart graph library. Unlike other graphing libraries, this one focuses on nodes in a graph having distinct ports through which connections to other nodes are formed. This helps in many concrete scenarios where it is important to distinguish not only which nodes are connected, but also how they are connected to each other.

Particularly, a lot of data flow and exchange problems can be reduced to such a flowchart. For example, an audio processing library may present its pipeline as a flowchart of segments that communicate with each other through audio sample buffers. Flow gives a convenient view onto this kind of problem, and even allows the generic visualisation of graphs in this format.
