Funds provides portable, purely functional data structures in Common Lisp. It includes tree based implementations for Array, Hash, Queue, Stack, and Heap.

This package provides Common Lisp math and statistics routines.

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.

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

Metatilities-base is the core of the metatilities Common Lisp library which implements a set of utilities.

Coleslaw is a static site generator written in Common Lisp.

This package provides a Common Lisp ASDF system auto-loading extension.

This package is a Python Numpy clone implemented in pure Common Lisp.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.

Trivial Monitored Thread offers a very simple (aka trivial) way of spawning threads and being informed when one any of them crash and die.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

CL-PPCRE is a portable regular expression library for Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

This is a client library to interact with the "mod.io" (https://mod.io) platform to manage "mods" or extensions for games and other applications. It covers the full v1 API and includes convenience methods to make interacting with the API as well as syncing mods and so on easy.

Py4CL is a bridge between Common Lisp and Python, which enables Common Lisp to interact with Python code. It uses streams to communicate with a separate python process, the approach taken by cl4py. This is different to the CFFI approach used by burgled-batteries, but has the same goal.

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.

A JSON Object Signing and Encryption (JOSE) implementation for Common Lisp.

This library implements a basic promise datastructure, which is useful for dealing with asynchronous behaviours. Importantly, this library does not use any other libraries or frameworks, and instead leaves the execution and state transition of promise objects in your control, making it easy to integrate.

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 CFFI bindings for the stb_vorbis audio library to Common Lisp.

BOOST-RE is a small, portable, lightweight, and quick, regular expression library for Common Lisp. It is a non-recursive, backtracking VM.

This package provides a Common Lisp system with a collection of common tests and operations to help handling pathnames. It does not actually deal in handling the accessing of files on the underlying system however.

This is a (currently) brief but usable wrap for SDL2_image.

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.

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.
