This library allows you to define custom indentation hints for your macros if the one recognised by SLIME automatically produces unwanted results.

This package provides CFFI bindings for the stb_vorbis audio library to Common Lisp.

One of the many things that didn't quite get into the Common Lisp standard was how to get a Lisp to output its call stack when something has gone wrong. As such, each Lisp has developed its own notion of what to display, how to display it, and what sort of arguments can be used to customize it. trivial-backtrace is a simple solution to generating a backtrace portably.

CL-DOT is a Common Lisp library for generating Graphviz dot output from arbitrary Lisp data.

HTML parser/emitter for CommonDoc.

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

Circular-Streams allows you to read streams circularly by wrapping real streams. Once you reach end-of-file of a stream, its file position will be reset to 0 and you're able to read it again.

Osicat is a lightweight operating system interface for Common Lisp on Unix-platforms. It is not a POSIX-style API, but rather a simple lispy accompaniment to the standard ANSI facilities.

Dufy is a library for exact color manipulation and conversion in various color spaces, which supports many color models.

This package provides KONS-9 which can be considered as a traditional user interface driven 3D application for general artists, or as a REPL-based development environment for technical artists and software developers. These two approaches can be seamlessly combined into a flexible and powerful workflow, where non-technical users can immediately benefit from software tools and extensions developed by technical users.

This is a Common Lisp library to load images in the PNG image format, both from files on disk, or streams in memory.

This library is a Common Lisp port of all the constants from the event codes header file found on Linux and FreeBSD.

cl-strings is a small, portable, dependency-free set of utilities that make it even easier to manipulate text in Common Lisp. It has 100% test coverage and works at least on sbcl, ecl, ccl, abcl and clisp.

This package provides an enhanced EVAL-WHEN macro that supports a shorthand for (eval-when (:compile-toplevel :load-toplevel :execute) ...), addressing concerns about verbosity.

ZPB-TTF is a TrueType font file parser that provides an interface for reading typographic metrics, glyph outlines, and other information from the file.

Domain specific language for producing TeX documents with Common Lisp.

EASY-ROUTES is yet another routes handling system on top of Hunchentoot. It's just glue code for Restas routing subsystem (CL-ROUTES).

It supports:

• dispatch based on HTTP method

• arguments extraction from the url path

• decorators

• URL generation from route names

This package provides EASY-ROUTES, EASY-ROUTES+DJULA and EASY-ROUTES+ERRORS systems.

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

cl-draw-cons-tree draws a cons tree in ASCII-art style.

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 is a terminfo database front end in Common Lisp. The package provides a method for determining which capabilities a terminal (e.g. "xterm") has and methods to compile or put commands to a stream.

Coleslaw is a static site generator written in Common Lisp.

This is a Common Lisp library providing RFC 3986 percent-encoding.

This is a Common Lisp library to make histograms using UTF-8 block characters.
