This is a teensy library that provides some functions to determine the mime-type of a file.

This is a Common Lisp library for reading PNG images.

This library is part of NUMCL. It provides a macro SPECIALIZED that performs a Julia-like dispatch on the arguments, lazily compiling a type-specific version of the function from the same code. The main target of this macro is speed.

Napa-FFT3 provides Discrete Fourier Transform (DFT) routines, but also buildings blocks to express common operations that involve DFTs: filtering, convolutions, etc.

BOOST-JSON is a simple JSON parsing library for Common Lisp.

CL-INTERPOL is a library for Common Lisp which modifies the reader so that you can have interpolation within strings similar to Perl or Unix Shell scripts. It also provides various ways to insert arbitrary characters into literal strings even if your editor/IDE doesn't support them.

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.

Trivial-features ensures that *FEATURES* is consistent across multiple Common Lisp implementations.

This library contains utilities for parsing Common Lisp code.

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.

RESTAS is a Common Lisp web application framework.

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.

Envy is a configuration manager for various applications. Envy uses an environment variable to determine a configuration to use. This can separate configuration system from an implementation.

This package provides a generic cache management facility with configurable and extensible cache replacement policies. The actual cached data can be stored anywhere, with cacle taking charge of keeping track of which entry is to be discarded next when more space is needed for a new entry.

CL-PDF is a cross-platform Common Lisp library for generating PDF files.

This is a library to find system font files. It works on systems with FontConfig on Linux, BSD. It does not have any foreign dependencies that aren't already directly available on the system.

cl-quicklisp-stats is a system that fetches and performs basic operations on the Quicklisp download statistics.

Smart-buffer provides an output buffer which changes the destination depending on content size.

This is a wrapper library to allow you to interface with the Valve SteamWorks API.

This package provides Common Lisp math and statistics routines.

This is a pure Common Lisp library to create, transform and render anti-aliased vectorial paths.

This Common Lisp package provides a regular expression engine.

This is a Common Lisp bindings library to libfond, a simple OpenGL text rendering engine.

This is a Common Lisp library providing a set of macros for generating lexical analyzers automatically. The lexers generated using cl-lex can be used with cl-yacc.
