This package extends the Common Lisp reader syntax such that is accepts Org files as Lisp source code files.

This package provides a UTF-8 string input stream over a binary stream for Common Lisp.

This package provides an ANSI CL adaptation of the SBCL mailbox utility.

This package provides Common Lisp bindings to the pango text layout library.

This library provides a WebSocket server and client implementation for Common Lisp.

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

This library defines most Common Lisp standard macros that can be defined in a portable way and that can generate portable code. Some of these macros may not be good enough as the final version for a typical implementation, but they will work.

This package provides support routines for the claw Common Lisp package.

Common Lisp port of Universal Tween Engine.

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 library allows for cooperative multitasking with help of cl-cont for continuations. It tries to mimic the API of bordeaux-threads as much as possible.

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

This library is an implementation of Deflate (RFC 1951) decompression, with optional support for ZLIB-style (RFC 1950) and gzip-style (RFC 1952) wrappers of deflate streams. It currently does not handle compression.

This library provides GTK4 bindings for Common Lisp via Gobject Introspection, in the cl-gtk4 ASDF system.

This package provides a functionality augmenting Hunchentoot error pages and logs with request and session information.

This library is a redefinition of the standard Common Lisp package that includes a number of renames and shadows.

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 is a system presenting a protocol for "file systems": things that present a collection of "files," which are things that have several attributes, and a central data payload. Most notably this includes the OS filesystem, but can also be used to address other filesystem-like things like archives, object stores, etc. in the same manner.

This library features a rectangle packer for sprite and texture atlases.

It can sometimes be useful to be able to parse chemical compounds in a user-friendly syntax into easy-to-manipulate s-expressions. You also want to be able to go in reverse. You could probably write your own parser — or you could just install the chemical-compounds package.

Command-Line-Args provides a main macro (command) that wraps a defun form and creates a new function that parses the command line arguments. It has support for command-line options, positional, and variadic arguments. It also generates a basic help message. The interface is meant to be easy and non-intrusive.

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

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

This is a Common Lisp Markdown to HTML converter, using esrap for parsing, and grammar based on peg-markdown.
