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

This library validates superclasses according to a simple substitution model, thereby greatly simplifying the definition of class mixins.

This package provides audio input and output functions to Common Lisp using bindings to the portaudio library.

This is a Common Lisp library to enable simple message pipelines.

This package provides a robust CSV parser and printer that tries to follow the fine print of de facto standards. It can be configured to choose which standard exactly.

Babel is a charset encoding and decoding library, not unlike GNU libiconv, but completely written in Common Lisp.

In the crowded space of Common Lisp HTML generators, Spinneret occupies the following coordinates:

• Modern. Targets HTML5. Does not treat XML and HTML as the same problem. Assumes you will be serving your documents as UTF-8.

• Composable. Makes it easy to refactor HTML generation into separate functions and macros.

• Pretty. Treats HTML as a document format, not a serialization. Output is idiomatic and readable, following the coding style of the HTML5 specification.

• Aggressive. If something can be interpreted as HTML, then it will be, meaning that some Lisp forms can't be mixed with HTML syntax. In the trade-off between 90% convenience and 10% correctness Spinneret is on the side of convenience.

• Bilingual. Spinneret (after loading spinneret/ps) has the same semantics in Lisp and Parenscript.

trivial-clipboard gives access to the system clipboard.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

SQL generator for Common Lisp.

These common lisp sources contain two variants of the Nelder-Mead algorithm. The original algorithm and a provably convergent, reliable variant by A. Bürmen et al, called the GRNMA.

Dynamic-mixins is for simple, dynamic class combination; it allows objects to be mixed and updated without manually defining many permutations.

jsown is a high performance Common Lisp JSON parser. Its aim is to allow for the fast parsing of JSON objects in Common Lisp. Recently, functions and macros have been added to ease the burden of writing and editing jsown objects.

jsown allows you to parse JSON objects quickly to a modifiable Lisp list and write them back. If you only need partial retrieval of objects, jsown allows you to select the keys which you would like to see parsed. jsown also has a JSON writer and some helper methods to alter the JSON objects themselves.

This package provides a client for SMTP.

Aims to be fast, modular, cachable and concise. It does so by defining each tag as a macro which expands to code printing the respective HTML source. Also employs a DSL for element attributes.

colorize is a Lisp library for syntax highlighting supporting the following languages: Common Lisp, Emacs Lisp, Scheme, Clojure, C, C++, Java, Python, Erlang, Haskell, Objective-C, Diff, Webkit.

The GNU Scientific Library for Lisp (GSLL) allows the use of the GNU Scientific Library (GSL) from Common Lisp. This library provides a full range of common mathematical operations useful to scientific and engineering applications. The design of the GSLL interface is such that access to most of the GSL library is possible in a Lisp-natural way; the intent is that the user not be hampered by the restrictions of the C language in which GSL has been written. GSLL thus provides interactive use of GSL for getting quick answers, even for someone not intending to program in Lisp.

BOOST-PARSE is a simple token parsing library for Common Lisp.

Parse-js is a Common Lisp package for parsing JavaScript (ECMAScript 3). It has basic support for ECMAScript 5.

This library is an extension of the Common Lisp Object System (CLOS) that allows a compiler to inline a generic function under certain conditions.

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

DEFPACKAGE-PLUS is an extensible DEFPACKAGE variant with predictable cross-platform behavior and some utilities useful for versioning.

This is a small OS portability library to retrieve and set file attributes not supported by the Common Lisp standard functions.
