Duologue is high-level interaction library for Common Lisp. It features coloured printing via cl-ansi-text and readline completion.

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

CLAWK is an AWK implementation embedded into Common Lisp.

Static dispatch is a Common Lisp library, inspired by inlined-generic-function, which allows standard Common Lisp generic function dispatch to be performed statically (at compile time) rather than dynamically (runtime). This is similar to what is known as "overloading" in languages such as C++ and Java.

The purpose of static dispatch is to provide an optimization in cases where the usual dynamic dispatch is too slow, and the dynamic features of generic functions, such as adding/removing methods at runtime are not required. An example of such a case is a generic equality comparison function. Currently generic functions are considered far too slow to implement generic arithmetic and comparison operations when used heavily in numeric code.

Vernacular is a build and module system for languages that compile to Common Lisp. It allows languages to compile to Lisp while remaining part of the Common Lisp ecosystem. Vernacular languages interoperate with Common Lisp and one another.

Vernacular handles locating files, compiling files into FASLs, tracking dependencies and rebuilding, and export and import between your new language, Lisp, and any other language Vernacular supports.

Vernacular builds on Overlord and is inspired by Racket.

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.

This is a YAML parser and emitter for Common Lisp built on top of libyaml.

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

FARE-MOP is a small collection of utilities using the MetaObject Protocol. It notably contains a SIMPLE-PRINT-OBJECT method, and a SIMPLE-PRINT-OBJECT-MIXIN mixin that allow you to trivially define PRINT-OBJECT methods that print the interesting slots in your objects, which is great for REPL interaction and debugging.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

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.

cl-xkb is a Common Lisp wrapper for the libxkbcommon keyboard handling library.

The library currently supports these xkb modules:

• Keysyms

• Library Context

• Include Paths

• Logging Handling

• Keymap Creation

• Keymap Components

• Keyboard State

• Compose and dead-keys support

Cells is a mature, stable extension to CLOS allowing one to create classes whose instances can have slot values determined by instance-specific formulas.

Tripod is a Common Lisp web server aiming to ease plain text, HTML, and Gopher website hosting.

Babel is a charset encoding and decoding library, not unlike GNU libiconv, but completely written in Common Lisp.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

This package provides Python style generators for Common Lisp. It also includes a port of itertools.

This package provides a Common Lisp system CHLOROPHYLL which implements an ANSI escape code functionality.

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

cl-change-case is a library to convert strings between camelCase, PascalCase, snake_case, param-case, CONSTANT_CASE and more.

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.

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

LMDB, the Lightning Memory-mapped Database, is an ACID key-value database with multiversion concurrency control. This package is a Common Lisp wrapper around the C LMDB library. It covers most of C LMDB's functionality, has a simplified API, much needed safety checks, and comprehensive documentation.

My Way is a Sinatra-compatible URL routing library.
