This package provides a PNG Common Lisp system to operate with Portable Network Graphics file format.

simple-optimization is a Common Lisp library providing a function to solve unconstrained optimization problems numerically using either the gradient descent or a quasi-Newton method.

This library can be used to print the licenses used by a Common Lisp project and its dependencies.

This package provides a safer variant of READ secure against internbombing, excessive input and macro characters.

This is only useful if you want to start a Swank server in a Lisp processes that doesn't run under Emacs. Lisp processes created by M-x slime automatically start the server.

This package provides a function to parse the PATH environment variable portably in Common Lisp.

Chemboy is a Common Lisp program for doing basic chemistry calculations. This package provides the text-based interface for Chemboy.

This is a Common Lisp library to calculate std140 or std430 layouts for a glsl UBO/SSBO.

RESTAS is a Common Lisp web application framework.

This package provides a pure-lisp implementation of a DNS client. It can be used to resolve hostnames, reverse-lookup IP addresses, and fetch other kinds of DNS records.

cl-rmath is a simple, autogenerated foreign interface for the standalone R API libRmath. There has been no effort to provide a high-level interface for the original library, instead, this library is meant to serve as a building block for such an interface.

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 extends the Common Lisp reader syntax such that is accepts Org files as Lisp source code files.

ASDF-FLV provides support for file-local variables through ASDF. A file-local variable behaves like *PACKAGE* and *READTABLE* with respect to LOAD and COMPILE-FILE: a new dynamic binding is created before processing the file, so that any modification to the variable becomes essentially file-local.

In order to make one or several variables file-local, use the macros SET-FILE-LOCAL-VARIABLE(S).

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

A common lisp library that provides extensible function result caching based on arguments (an expanded form of memoization).

RUTILS is a syntactic utilities package for Common Lisp.

This library is an implementation of the Secure Hash Algorithm 3 (SHA-3), also known as Keccak. The implementation is constrained to messages with an integral number of octets,i.e. sub-byte length messages are not supported.

The 3d-math library implements types, operators, and algorithms commonly used in math for 2D and 3D graphics. It supersedes and combines the prior libraries 3d-vectors, 3d-matrices, 3d-quaternions, and 3d-transforms. The new API is largely but not entirely backwards compatible, and adds new functionality.

Library to fuzzily parse time and date strings into a universal-time timestamp.

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

This is a library for access to atomic operation primitives such as compare-and-swap. It aims to be a rather thin layer over what the implementations offer.

This package provides a PEM (Privacy-Enhanced Mail) parser for Common Lisp.

cl-charms is an interface to libcurses in Common Lisp. It provides both a raw, low-level interface to libcurses via CFFI, and a more higher-level lispier interface.
