This is a Common Lisp library for solving linear programming problems.

This Common Lisp library contains the core classes and pixel access macros for the Opticl image processing library.

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.

This is a common lisp library to easily pluralize and singularize English and Portuguese words. This is a port of the ruby ActiveSupport Inflector module.

This package provides a standard interface to the various package lock implementations of Common Lisp.

LMDB, the Lightning Memory-mapped Database, is an ACID key-value database with multiversion concurrency control. This package is a Common Lisp wrapper around the C LMDB library. It covers most of C LMDB's functionality, has a simplified API, much needed safety checks, and comprehensive documentation.

This library lets you build a metaclass which in turn lets you specify extra slot options in its classes. Options may be easily inspected and custom inheritance may be set up. The Meta-Object Protocol (MOP) is used for the implementation - through closer-mop. Some convenience function for processing slot options are also available.

Possible use case: you want to automatically set up some definitions based on some slots, but you want to have control over it right in the class definition.

Germinal is a server for the Gemini protocol, written in Common Lisp.

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.

This package provides CFFI bindings for Common Lisp to the Cairo C library.

This package provides GNU gettext completely implemented in Common Lisp without any C library bindings.

This a Common Lisp library for reading and writing binary data. It is based on code from chapter 24 of the book Practical Common Lisp.

This package provides an ANSI CL adaptation of the SBCL mailbox utility.

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

This is a small Common Lisp library that finds an open port within a range.

This library allows you to open native file dialogs to open and save files. This is useful if you have an application that's primarily text based and would like a more convenient file selection utility, or if you are working with a UI toolkit that does not offer a way to access the native file dialogs directly.

This is a Common Lisp library to present tabular data in ascii-art tables.

This package provides a small utility library to open a thing (usually a file or URL) in an appropriate handler (usually an external file manager or browser).

Sketch is a Common Lisp environment for the creation of electronic art, visual design, game prototyping, game making, computer graphics, exploration of human-computer interaction and more. It is inspired by the Processing language and shares some of the API.

Parseq (pronounced parsec) is a parsing library for common lisp. It can be used for parsing lisp's sequences types: strings, vectors (e.g. binary data) and lists. Furthermore, parseq is able to parse nested structures such as trees (e.g. lists of lists, lists of vectors, vectors of strings).

Parseq uses parsing expression grammars (PEG) that can be defined through a simple interface. Extensions to the standard parsing expressions are available. Parsing expressions can be parameterised and made context aware. Additionally, the definition of each parsing expression allows the arbitrary transformation of the parsing tree.

The library is inspired by Esrap and uses a very similar interface. No code is shared between the two projects, however. The features of Esrap are are mostly included in parseq and complemented with additional, orthogonal features. Any resemblance to esrap-liquid is merely coincidental.

This is a utility kit for cl-sdl2 that provides something similar to GLUT. However, it's also geared at being useful for "real" applications or games.

This is a library to allow easy handling of external processes, and primarily to get their output. It handles proper copying of the standard and error outputs of the process simultaneously, both in a sequential and parallel fashion. It also features a lazy directory switching mechanism, to avoid running into parallelism problems when having to change directory.

This package provides GNU gettext completely implemented in Common Lisp without any C library bindings.

This a Common Lisp library for reading and writing binary data. It is based on code from chapter 24 of the book Practical Common Lisp.
