Authentic provides a light-weight and extendible solution to user/password management for Common Lisp applications. It has features such as safe password storage in a database, password reset, user confirmation tokens, and user authentication.

CL-UNICODE is a portable Unicode library Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

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.

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

Lack is a Common Lisp library which allows web applications to be constructed of modular components. It was originally a part of Clack, however it's going to be rewritten as an individual project since Clack v2 with performance and simplicity in mind.

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

The NUMPY-FILE-FORMAT library is a Common Lisp library for reading and writing NumPy .npy and .npz files.

This is a keymap facility for Common Lisp inspired by Emacsy (keymap.scm) which is inspired by Emacs.

• Support prefix keys to other keymaps. For instance, if you prefix my-mode-map with C-c, then all bindings for my-mode will be accessible after pressing C-c.

• List all bindings matching a given prefix. (Also known as which-key in Emacs.)

• List the bindings associated to a command.

• Support multiple inheritance.

• Support keycode.

• Validate keyspec at compile time.

• define-key can set multiple bindings in a single call.

• Support multiple scheme to make it easy to switch between, say, Emacs-style and VI-style bindings. This orthogonality to keymaps composes better than having multiple keymaps: changing scheme applies to the entire program, which is easier than looping through all keymaps to change them.

• Translate keyspecs as a fallback. For instance if shift-a is not bound, check A.

• Behaviour can be customized with global parameters such as *print-shortcut*.

• The compose function can merge multiple keymaps together.

• Support multiple arguments when that makes sense (e.g. multiple keymaps for lookup-key).

• Key remapping à-la Emacs.

• Typed keymaps, i.e. keymaps where bound values can only be of a given type. This is convenient to catch typos, for instance when binding 'FOO instead of #'FOO.

High performance JSON encoder and decoder. Currently support: SBCL, CCL.

One of the many things that didn't quite get into the Common Lisp standard was how to get a Lisp to output its call stack when something has gone wrong. As such, each Lisp has developed its own notion of what to display, how to display it, and what sort of arguments can be used to customize it. trivial-backtrace is a simple solution to generating a backtrace portably.

This library allows you to implement and enforce proper finalization of compile-time constructs while building Lisp source files.

It produces two systems: asdf-finalizers and list-of.

This is a websocket server for Common Lisp using usockets to be portable between implementations and operating systems. It has a programming interface that allows for multiple websocket apps per server using Common Lisp keywords for different websocket events. It has useful restarts and customizable errors.

The Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.

Dynamic-mixins is for simple, dynamic class combination; it allows objects to be mixed and updated without manually defining many permutations.

A Common Lisp library implementing a few different kinds of queues:

• Bounded and unbounded FIFO queues.

• Lossy bounded FIFO queues that drop elements when full.

• Unbounded random-order queues that use less memory than unbounded FIFO queues.

Additionally, a synchronization wrapper is provided to make any queue conforming to the jpl-queues API thread-safe for lightweight multithreading applications. (See Calispel for a more sophisticated CL multithreaded message-passing library with timeouts and alternation among several blockable channels.)

NClasses provides helper macros to help write classes, conditions, generic functions, and CLOS code in general with less boilerplate.

It's a fork of hu.dwim.defclass-star. It includes some bug fixes and extra features like type inference.

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

This package provides a common lisp CFFI wrapper for the SciPy version of Cephes special functions.

MODULARIZE is an attempt at providing a common interface to segregate major application components. This is achieved by adding special treatment to packages. Each module is a package that is specially registered, which allows it to interact and co-exist with other modules in better ways. For instance, by adding module definition options you can introduce mechanisms to tie modules together in functionality, hook into each other and so on.

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

RESTAS is a Common Lisp web application framework.

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

This package implements an algorithm for the spelling of enharmonics and dealing with ties and dots in rhythm notation.

This library can be used to display a progress bar on one line.
