This is a Common Lisp autowrapping facility for quickly creating clean and lean bindings to C libraries.

This package provides a pure-lisp implementation of a DNS client. It can be used to resolve hostnames, reverse-lookup IP addresses, and fetch other kinds of DNS records.

This package provides matrix algebra functions for Common Lisp.

This library converts the elements from GObject Introspection into Common Lisp-style definitions, based on cl-gobject-introspection.

This package provides a small utility library to open a thing (usually a file or URL) in an appropriate handler (usually an external file manager or browser).

This is a Common Lisp library to make histograms using UTF-8 block characters.

This package provides a statistical computing environment for Common Lisp.

Magic (ed) is a tiny editing facility for Common Lisp, where you can directly load, edit, manipulate and evaluate file or file content from REPL. This package also can be a starting point for people who are not accustomed to Emacs or SLIME and would like to continue using their default terminal/console editor with Common Lisp.

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

This package provides CFFI bindings to convert between different character encodings using iconv.

cl-css-lite is a library for generating CSS from an s-exp based syntax. When compiled with Parenscript loaded in the Lisp image, it also provides the same CSS generation facilities in Parenscript-generated JavaScript code.

This package provides a pure-lisp implementation of a DNS client. It can be used to resolve hostnames, reverse-lookup IP addresses, and fetch other kinds of DNS records.

CL-UNICODE is a portable Unicode library Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

This library contains a lexer for syntaxes that use shell-like rules for quoting and commenting. It is a port of the shlex module from Python’s standard library.

This library provides purely functional dictionaries and sets in Common Lisp based on the hash array-mapped trie data structure.

This package provides a Common Lisp wrapper system for the SDL 2.0 C Library.

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.

This package provides a small utility library to open a thing (usually a file or URL) in an appropriate handler (usually an external file manager or browser).

ISSR core provides functions and variables for ISSR server modules so that different servers can behave similarly. The most important features are Document Object Model differencing to generate instructions to update a DOM, and DOM cleaning, to ensure that all remote DOMs are the same.

Dissect is a small Common Lisp library for introspecting the call stack and active restarts.

ST-JSON (ST because it originated at Streamtech) is a Common Lisp library for encoding and decoding JSON values (as specified on json.org).

This library does mostly the same thing as CL-JSON, but is simpler and more precise about types (distinguishing boolean false, the empty array, and the empty object).

This package contains a few utility functions from the LispWorks library that are used in software such as ContextL.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

This is a small library providing the ISO-639 language code to language name mapping.
