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

MGL-GPR is a library of evolutionary algorithms such as Genetic Programming (evolving typed expressions from a set of operators and constants) and Differential Evolution.

parse-number is a library of functions for parsing strings into one of the standard Common Lisp number types without using the reader. parse-number accepts an arbitrary string and attempts to parse the string into one of the standard Common Lisp number types, if possible, or else parse-number signals an error of type invalid-number.

This package provides Common Lisp bindings to POSIX message queue, an IPC method that is easy to use and quick to setup.

This package provides Common Lisp FFI bindings for libwayland, primarily for the mahogany window manager.

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.

cl-annot is an general annotation library for Common Lisp.

SB-CGA is a computer graphics algebra library for Common Lisp.

Despite the prefix it is actually portable - but optimizations that make it fast (using SIMD instructions) are currently implemented for SBCL/x86-64 only.

This package provides a Common Lisp library for getting the battery information.

This is a baseline JPEG codec written in Common Lisp. It can be used for reading and writing JPEG image files.

Very basic library for dealing with CL's hash tables. The idea was spawned through working with enough JSON APIs and config files, causing a lot of headaches in the process.

CL-FAST-ECS is a Common Lisp library providing an implementation of the ECS pattern, primarily focused on speed and interactive development.

ECS is an architectural data-oriented design pattern that allows for the effective processing of a large number of in-game objects while keeping the code and data separated. This provides flexibility in the way that game objects are built at runtime.

This library is an SDL wrapper as part of an umbrella project that provides cross-platform packages for building large, interactive applications in Common Lisp.

This package provides a priority queue implemented with an array-based heap.

cl-css-lite is a library for generating CSS from an s-exp based syntax. When compiled with Parenscript loaded in the Lisp image, it also provides the same CSS generation facilities in Parenscript-generated JavaScript code.

This package provides Common Lisp extension to the MOP to allow abstract, final and singleton classes.

This package provides the getopt function to parse command-line options. The options are organized in valid options, other arguments and unknown arguments. Optional Lisp conditions for error situations are also defined.

Varjo is a Lisp to GLSL compiler. Vari is the dialect of lisp Varjo compiles. It aims to be as close to Common Lisp as possible, but naturally it is statically typed so there are differences.

F2cl is a Common Lisp library that can convert Fortran 77 code into Common Lisp code.

With static-vectors, you can create vectors allocated in static memory.

CL-FAD (for "Files and Directories") is a thin layer atop Common Lisp's standard pathname functions. It is intended to provide some unification between current CL implementations on Windows, OS X, Linux, and Unix. Most of the code was written by Peter Seibel for his book Practical Common Lisp.

This is a Common Lisp macro for defining temporary caches that invalidate based on expressions evaluating to different values.

My Way is a Sinatra-compatible URL routing library.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.
