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

This library features a rectangle packer for sprite and texture atlases.

An implementation of the exponential backoff algorithm in Common Lisp. Inspired by the implementation found in Chromium. Read the header file to learn about each of the parameters.

Duologue is high-level interaction library for Common Lisp. It features coloured printing via cl-ansi-text and readline completion.

This library is a collection of utilities for writing compiler macros. It is intended to make it possible to make compiler macros much more useful, by granting them access to lexical type information, making the protocol for declining expansion more convenient, and establishing some information for signaling optimization advice to programmers. Some utilities to support this, especially for reasoning on types, are also included.

Alexandria is a collection of portable utilities. It does not contain conceptual extensions to Common Lisp. It is conservative in scope, and portable between implementations.

ADOPT is a simple UNIX-style option parser in Common Lisp, heavily influenced by Python's optparse and argparse.

PAX provides an extremely poor man's Explorable Programming environment. Narrative primarily lives in so called sections that mix markdown docstrings with references to functions, variables, etc, all of which should probably have their own docstrings.

The primary focus is on making code easily explorable by using SLIME's M-. (slime-edit-definition). See how to enable some fanciness in Emacs Integration. Generating documentation from sections and all the referenced items in Markdown or HTML format is also implemented.

With the simplistic tools provided, one may accomplish similar effects as with Literate Programming, but documentation is generated from code, not vice versa and there is no support for chunking yet. Code is first, code must look pretty, documentation is code.

This library is a portable socket interface that allows CL programs to open connected (client) stream sockets to network services.

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

A library and command line utility to automatically indent Common Lisp source files.

This Common Lisp library converts strings, symbols and keywords between any of the following typographical cases: PascalCase, camelCase, snake_case, kebab-case (lisp-case).

This package contains an implementation of RFC 2388, which is used to process form data posted with HTTP POST method using enctype "multipart/form-data".

string-pokemonize provides a function that alternates uppercase and lowercase characters for a given string.

This library is a small interface to portable but nonstandard introspection of Common Lisp environments. It is intended to allow a bit more compile-time introspection of environments in Common Lisp.

Quite a bit of information is available at the time a macro or compiler-macro runs; inlining info, type declarations, that sort of thing. This information is all standard - any Common Lisp program can (declare (integer x)) and such.

This info ought to be accessible through the standard &environment parameters, but it is not. Several implementations keep the information for their own purposes but do not make it available to user programs, because there is no standard mechanism to do so.

This library uses implementation-specific hooks to make information available to users. This is currently supported on SBCL, CCL, and CMUCL. Other implementations have implementations of the functions that do as much as they can and/or provide reasonable defaults.

nontrivial-gray-streams is a compatibility system for Gray streams, which is an extension to Common Lisp that makes it possible to implement Common Lisp streams using generic functions.

BORDEAUX-THREADS is a proposed standard for a minimal MP/Threading interface. It is similar to the CLIM-SYS threading and lock support.

s-sysdeps is an abstraction layer over platform dependent functionality. This simple package is used as a building block in a number of other projects.

s-sysdeps abstracts:

• managing processes,

• implementing a standard TCP/IP server,

• opening a client TCP/IP socket stream,

• working with process locks.

Simple library to create temporary directories.

Typo is a portable library for Common Lisp that does approximate reasoning about types, but without consing.

This library is a universal interface to the operating system package manager. It has extensive support for Guix, among others:

• package listing and searching;

• package installation and uninstallation;

• package file listing;

• profile listing;

• manifest listing and installation;

• generation listing, switching and deletion.

CL-octet-streams is a library implementing in-memory octet streams for Common Lisp. It was inspired by the trivial-octet-streams and cl-plumbing libraries.

The Metering System is a portable Common Lisp code profiling tool. It gathers timing and consing statistics for specified functions while a program is running.

The Plump-SEXP library is a backend for Plump which can convert between S-expressions and the Plump DOM.
