This package extends the Common Lisp reader syntax such that is accepts Org files as Lisp source code files.

Schemeish implements several useful Scheme constructs for Common Lisp. These include named-let, define, scheme argument lists, and a shortcut to FUNCALL with [] instead of ().

NDebug provides a small set of utilities to make graphical (or, rather non-REPL-resident) Common Lisp applications easier to integrate with the standard Lisp debugger (*debugger-hook*, namely) and implementation-specific debugger hooks (via trivial-custom-debugger), especially in a multi-threaded context.

The Babel library solves a similar problem while understanding more encodings. Trivial UTF-8 was written before Babel existed, but for new projects you might be better off going with Babel. The one plus that Trivial UTF-8 has is that it doesn't depend on any other libraries.

This package provides the Common Lisp part of the emacs-slite test runner.

Trivial-Benchmark runs a block of code many times and outputs some statistical data for it. On SBCL this includes the data from time, for all other implementations just the real-time and run-time data. However, you can extend the system by adding your own metrics to it, or even by adding additional statistical computeations.

This package provides a Common Lisp system implementing event bus.

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-tar is a Common Lisp library providing a high-level interface for interacting with tar archives.

This is a Common Lisp library to extract EXIF information from image files.

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

This package provides a configuration library that adds the ability for Lem to manage packages within the user configuration directory.

This package provides an automatic generator for ASDF's .asd files.

Portable document preparation system.

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

This package implements a simple interface for using WebSockets via Common Lisp.

UCONS is a Common Lisp library providing unique conses. Unique conses are different from regular conses in that, in addition to their car and cdr, they maintain a table of past users. Also, the cdr of each ucons is restricted to other uconses or nil. Uconses are meant for those situations where even reusing regular conses (to avoid consing) is too computationally expensive.

GECO (Genetic Evolution through Combination of Objects) is an extensible, object-oriented framework for prototyping genetic algorithms in Common Lisp.

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

This is a bindings library to libout123 which allows easy cross-platform audio playback.

This package provides CFFI bindings for the stb_vorbis audio library to Common Lisp.

The GRAPH Common Lisp library provides a data structures to represent graphs, as well as some graph manipulation and analysis algorithms (shortest path, maximum flow, minimum spanning tree, etc.).

This package is a list manipulation library for Common Lisp inspired by Haskell package Data.List.

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.
