This library provides arbitrary precision (floating point) real numbers in Common Lisp.

Utility library for handling bit vectors, bit vector arithmetic, and universal integer type conversions between bit-vectors, byte-vectors, octals, decimals, and hexadecimal notation.

Tripod is a Common Lisp web server aiming to ease plain text, HTML, and Gopher website hosting.

This is a bindings and wrapper library to libmpg123 allowing for convenient, extensive, and fast decoding of MPEG1/2/3 (most prominently mp3) files.

qbase64 provides a fast and flexible base64 encoder and decoder for Common Lisp.

CHRONICITY is Common Lisp natural language date and time parser inspired by Ruby's Chronic.

The 3d-math library implements types, operators, and algorithms commonly used in math for 2D and 3D graphics. It supersedes and combines the prior libraries 3d-vectors, 3d-matrices, 3d-quaternions, and 3d-transforms. The new API is largely but not entirely backwards compatible, and adds new functionality.

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.

A Common Lisp library for computing differences between sequences based on the Python difflib module.

simple-matrix is a Common Lisp library implementing some functions to work with matrices.

The 3D-Spaces library implements a number of spatial query data structures; structures that can answer spatial range queries for optimized lookup, particularly suited for games.

CF is a Common Lisp library for doing computations using continued fractions.

Forge is a generic build system. Refer to documentation for the specific kind of project you're building to get the full picture.

The Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.

This is a Common lisp library to unify access to the most common dictionary-like data structures.

Salza2 is a Common Lisp library for creating compressed data in the zlib, deflate, or gzip data formats, described in RFC 1950, RFC 1951, and RFC 1952, respectively.

This is a YAML parser and emitter for Common Lisp built on top of libyaml.

Max’s Parser Combinators is a simple and pragmatic library for writing parsers and lexers based on combinatory parsing. MaxPC is capable of parsing deterministic, context-free languages, provides powerful tools for parse tree transformation and error handling, and can operate on sequences and streams. It supports unlimited backtracking, but does not implement Packrat Parsing. Instead, MaxPC achieves good performance through its optimized primitives, and explicit separation of matching and capturing input. In practice, MaxPC parsers perform better on typical computer languages—when compared to Packrat parsers—at the expense of not producing linear-time parsers.

This Common Lisp library provides function to make QR codes and to save them as PNG files.

cl-strings is a small, portable, dependency-free set of utilities that make it even easier to manipulate text in Common Lisp. It has 100% test coverage and works at least on sbcl, ecl, ccl, abcl and clisp.

This is a Common Lisp version of UglifyJS, a JavaScript compressor. It works on data produced by parse-js to generate a minified version of the code. Currently it can:

• reduce variable names (usually to single letters)

• join consecutive var statements

• resolve simple binary expressions

• group most consecutive statements using the sequence operator (comma)

• remove unnecessary blocks

• convert IF expressions in various ways that result in smaller code

• remove some unreachable code

CLACHE provides a general caching facility for Common Lisp. The API is similar to the standard hash-table interface.

This is a Common Lisp library to build and compose SXQL queries dynamically.

This is an optimized Common Lisp library of Bob Jenkins' ISAAC-32 and ISAAC-64 algorithms, which are fast cryptographic random number generators: Indirection, Shift, Accumulate, Add, and Count.
