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

Common Lisp library for channel-based concurrency. In a nutshell, you create various threads sequentially executing tasks you need done, and use channel objects to communicate and synchronize the state of these threads.

The main purpose of this n+2nd reimplementation of quasiquote is enable matching of quasiquoted patterns, using Optima or Trivia.

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

Colony provides a system and workflow that helps describe the elements needed to write 2D or 3D games. It was designed with several domain specific languages that make it easier to describe, manipulate, and use assets commonly found in game making. Such assets include (but are not limited to) textures, materials, shader programs, and scene trees of actors that are available for instantiation. Colony Engine also knows how to accept input from keyboards and most joysticks and gamepads.

The component system is a hybrid model between an ECS and an object model. The components are defined similar to CLOS defclass, and regular generic methods can be used with them. Components are added to Actors which represent game concepts like players, scenery, effects, etc. We define a component protocol invoked by Colony Engine to move your components to the next state and render them each frame.

MAP-BIND is a macro that allows visual grouping of variables with their corresponding values in calls to mapping operators when using an inline LAMBDA.

Moira is a library for monitoring and, if necessary, restarting long-running threads. In principle, it is like an in-Lisp process supervisor.

This library is a redefinition of the standard Common Lisp package that includes a number of renames and shadows.

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 is a simple date and time library.

deeds allows for efficient event delivery to multiple handlers with a complex event filtering system.

This package provides easy access to the defining class and its options during initialization or reinitialization of its subcomponents.

This library provides a tiny Common Lisp wrapper around setlocale(3) and can be used in conjunction with other FFI wrappers like cl-charms.

This package contains the specification of all functions and variables from GLSL as data.

hdf5-cffi is a CFFI wrapper for the HDF5 library.

Framework for representing and manipulating documents.

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.

A miniature toolkit that contains some useful shifting/popping/pushing functions for arrays and vectors. Originally from Plump.

This package provides a shim between Python3 (specifically, the CPython implementation of Python) and Common Lisp.

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.

atomichron is a Common Lisp library which implements a time meter which tracks how many times a form is evaluated, and how long evaluation takes. It uses atomic instructions so that meters will present correct results in the presence of multiple threads, while trying to minimize synchronization latency.

cl-mysql is a Common Lisp implementation of a MySQL wrapper.

This package provides an implementation of the flexichain protocol, allowing client code to dynamically add elements to, and delete elements from a sequence (or chain) of such elements.

cl-transmission is a library to interface with the Transmission torrent client using its RPC (remote procedure call).
