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 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 package provides an ASN.1 encoder/decoder for Common Lisp.

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

This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.

This is a Common Lisp utilities library originating from the Zombie Raptor game engine project.

cl-flamegraph is a wrapper around SBCL's statistical profiler. It saves stack traces of profiled code in a form suitable for processing by the flamegraph.pl script, which is available in the Guix package flamegraph.

Plump is a parser for HTML/XML-like documents, focusing on being lenient towards invalid markup. It can handle things like invalid attributes, bad closing tag order, unencoded entities, inexistent tag types, self-closing tags and so on. It parses documents to a class representation and offers a small set of DOM functions to manipulate it. It can be extended to parse to your own classes.

This package provides Common Lisp bindings for libev.

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 server part of AllegroServe can be used either as a standalone web server or a module loaded into an application to provide a user interface to the application. AllegroServe's proxy ability allows it to run on the gateway machine between some internal network and the Internet. AllegroServe's client functions allow Lisp programs to explore the web.

This Common Lisp library provides a simple FIFO implementation with no external dependencies.

cl-cffi-gtk is a Lisp binding to GTK+ 3 (GIMP Toolkit) which is a library for creating graphical user interfaces.

CL-Ledger is a Common Lisp port of the Ledger double-entry accounting system.

Support library for numcl. Registers a function as an additional form that is considered as a candidate for a constant.

CL-random-forest is an implementation of Random Forest for multiclass classification and univariate regression written in Common Lisp. It also includes an implementation of Global Refinement of Random Forest.

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

This package provides a collection of types, functions and macros. Some of the functionality is implemented from Graham's On Lisp and Seibel's Practical Common Lisp.

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.

Lack is a Common Lisp library which allows web applications to be constructed of modular components. It was originally a part of Clack, however it's going to be rewritten as an individual project since Clack v2 with performance and simplicity in mind.

This package provides CFFI binding to libmixed audio library for Common Lisp with support of other audio formats available on GNU/Linux systems:

• Alsa

• Jack

• Openmpt

• PulseAudio

• Flac (via CL-FLAC)

• Mpg123 (via CL-MPG123)

• Ogg/vorbis (via CL-VORBIS)

• Out123 (via CL-OUT123)

• WAV

This lisp library handles physical quantities which consist of

• value / magnitude

• uncertainty / error

• unit

where the type of the value can be any subtype of real. For the uncertainty, both absolute and relative values are possible. Combinations of lisp symbols or strings are used to describe units. User defined units including abbreviations and prefixes are supported. Error propagation and unit checking is performed for all defined operations.

This package allows flexible specification of package-local preferences.

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