This is an extension library to pathname-utils, to allow dealing with common problems with filesystems, such as listing files, probing file types, determining default directories, etc.

This library provides a WebSockets extension for the Huchentoot web server.

DAEMON provides the functionality of daemonizing Common Lisp processes on UNIX like platforms.

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

Smart-buffer provides an output buffer which changes the destination depending on content size.

This is a trivial utility for distinguishing between a process running in a real terminal window and a process running in a dumb one, e.g. emacs-slime.

This library contains generic hacks meant to be used in any project. It was originally developed for the Cells library.

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

RE is a small, portable, lightweight, and quick, regular expression library for Common Lisp. It is a non-recursive, backtracing VM.

This is a library to allow easy handling of external processes, and primarily to get their output. It handles proper copying of the standard and error outputs of the process simultaneously, both in a sequential and parallel fashion. It also features a lazy directory switching mechanism, to avoid running into parallelism problems when having to change directory.

This is a dead-simple, non validating, inline CSS generator for Common Lisp. Its goals are axiomatic syntax, simple implementation to support portability, and boilerplate reduction in CSS.

This package contains a Gemini client library for Common Lisp. A subsystem offers an experimental GUI Gemini client.

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

This library provides a wrapper type for secret values, to reduce the risk of accidentally revealing them.

Parseq (pronounced parsec) is a parsing library for common lisp. It can be used for parsing lisp's sequences types: strings, vectors (e.g. binary data) and lists. Furthermore, parseq is able to parse nested structures such as trees (e.g. lists of lists, lists of vectors, vectors of strings).

Parseq uses parsing expression grammars (PEG) that can be defined through a simple interface. Extensions to the standard parsing expressions are available. Parsing expressions can be parameterised and made context aware. Additionally, the definition of each parsing expression allows the arbitrary transformation of the parsing tree.

The library is inspired by Esrap and uses a very similar interface. No code is shared between the two projects, however. The features of Esrap are are mostly included in parseq and complemented with additional, orthogonal features. Any resemblance to esrap-liquid is merely coincidental.

Sketch is a Common Lisp environment for the creation of electronic art, visual design, game prototyping, game making, computer graphics, exploration of human-computer interaction and more. It is inspired by the Processing language and shares some of the API.

This library provides functions for determining the value types of Common Lisp forms, based on type information contained in the environment.

In order for this library to work the values types of variables and return types of functions have to be declared.

Macros and symbol-macros are fully expanded and all special forms, except CATCH, are supported.

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

dbi is a Common Lisp library providing a database independent interface for MySQL, PostgreSQL and SQLite.

fmt provides an alternative to the Common Lisp format function by utilizing s-expressions for formatting directives instead of control strings.

Clop is a Common Lisp library for parsing strings in the TOML configuration file format.

This system implements a general definitions introspection library. It gives you the ability to retrieve definitions or bindings associated with designators such as symbols, packages, and names in general. For instance, it allows you to retrieve all function, type, variable, method, etc. definitions of a symbol.

YASON is a Common Lisp library for encoding and decoding data in the JSON interchange format.
