Vom is a logging library for Common Lisp. It's goal is to be useful and small. It does not provide a lot of features as other loggers do, but has a small codebase that's easy to understand and use.

Html-entities is a Common Lisp library that lets you encode and decode entities in HTML.

Parse INI formatted files into a Common Lisp list structure.

cl-random is a library for generating random draws from various commonly used distributions, and for calculating statistical functions, such as density, distribution and quantiles for these distributions.

A Common Lisp client library for Apache Kafka.

Markup allows the use of HTML syntax with in Common Lisp code. This has the advantage of being able to copy HTML snippets and have them instantly be functional, less double quotes than a s-expression approach, and designers will be able to understand the embedded HTML.

This is a portable Universal Resource Identifier library for Common Lisp programs. It parses URI according to the RFC 2396 specification.

UCONS is a Common Lisp library providing unique conses. Unique conses are different from regular conses in that, in addition to their car and cdr, they maintain a table of past users. Also, the cdr of each ucons is restricted to other uconses or nil. Uconses are meant for those situations where even reusing regular conses (to avoid consing) is too computationally expensive.

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

CEPL (Code Evaluate Play Loop ) is a lispy and REPL-friendly Common Lisp library for working with OpenGL.

Its definition of success is making the user feel that GPU programming has always been part of the languages standard.

The usual approach to using CEPL is to start it at the beginning of your Lisp session and leave it open for the duration of your work. You can then treat the window it creates as just another output for your graphics, analogous to how *standard-output* is treated for text.

A mixture of features from eRuby and HTML::Template. You could name it "Yet Another LSP" (LispServer Pages) but it's a bit more than that and not limited to a certain server or text format.

cl-pass is a password hashing and verification library.

This package provides a standard way to canonicalize slot values.

Parse-Declarations is a Common Lisp library to help writing macros which establish bindings. To be semantically correct, such macros must take user declarations into account, as these may affect the bindings they establish. Yet the ANSI standard of Common Lisp does not provide any operators to work with declarations in a convenient, high-level way. This library provides such operators.

This package provides a KDL reader/writer for Common Lisp.

This is a Common Lisp library consisting of a collection of useful GPU shader functions, written with Shadow.

3bz is an implementation of Deflate decompression (RFC 1951) optionally with zlib (RFC 1950) or gzip (RFC 1952) wrappers, with support for reading from foreign pointers (for use with mmap and similar, etc), and from CL octet vectors and streams.

This library provides trivial percent encoding and decoding functions for URLs.

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

This package provides an implementation of the hash-set data structure. It has constant time lookup, insertion and deletion.

This package provide a Common Lisp library for .zip-file reading and writing.

This library is a small interface to portable but nonstandard introspection of Common Lisp environments. It is intended to allow a bit more compile-time introspection of environments in Common Lisp.

Quite a bit of information is available at the time a macro or compiler-macro runs; inlining info, type declarations, that sort of thing. This information is all standard - any Common Lisp program can (declare (integer x)) and such.

This info ought to be accessible through the standard &environment parameters, but it is not. Several implementations keep the information for their own purposes but do not make it available to user programs, because there is no standard mechanism to do so.

This library uses implementation-specific hooks to make information available to users. This is currently supported on SBCL, CCL, and CMUCL. Other implementations have implementations of the functions that do as much as they can and/or provide reasonable defaults.

HARMONY is a library that provides you with audio processing tools as well as an audio server to play back music, sfx, and so forth. It is most suited for use in a game engine, but may feasibly also be used for more advanced things such as a DAW

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
