A common lisp library that provides extensible function result caching based on arguments (an expanded form of memoization).

exit-hooks provides a portable way to automatically call some user-defined function when exiting Common Lisp (both quit from the REPL or a kill in a shell). Like atexit in C and Python or Java’s Runtime.addShutdownHook(). It currently supports SBCL, CCL, ECL, ABCL, Allegro CL, clisp and CMUCL. Before exit-hooks, there was no portable way of doing so and no staightforward way to use an exit hook on ABCL. It can be used for tasks like parmenantly save something when exiting Lisp.

Defstar is a collection of Common Lisp macros that can be used in place of defun, defmethod, defgeneric, defvar, defparameter, flet, labels, let* and lambda. Each macro has the same name as the form it replaces, with a star added at the end, e.g. defun. (the exception is the let* replacement, which is called *let).

This package provides a simple yet powerful value inheritance scheme.

simple-matrix is a Common Lisp library implementing some functions to work with matrices.

A client for the Stripe payment API.

CL-HEAP provides various implementations of heap data structures (a binary heap and a Fibonacci heap) as well as an efficient priority queue.

This is a Common Lisp library to change the capitalization and spacing of a string or a symbol. It can convert to and from Lisp, english, underscore and camel-case rules.

Scrape on-line documentation out of a running Lisp image.

This library is a little experiment in reducing verbosity in Common Lisp, inspired by BODOL (https://github.com/bodil/BODOL).

Common Lisp port of Universal Tween Engine.

CXML implements a namespace-aware, validating XML 1.0 parser as well as the DOM Level 2 Core interfaces. Two parser interfaces are offered, one SAX-like, the other similar to StAX.

This library generates sdf (https://steamcdn-a.akamaihd.net/apps/valve/2007/SIGGRAPH2007_AlphaTestedMagnification.pdf), psdf and msdf (https://github.com/Chlumsky/msdfgen/files/3050967/thesis.pdf) atlases.

Closer to MOP is a compatibility layer that rectifies many of the absent or incorrect CLOS MOP features across a broad range of Common Lisp implementations.

cl-random is a library for generating random draws from various commonly used distributions, and for calculating statistical functions, such as density, distribution and quantiles for these distributions.

CLAWK is an AWK implementation embedded into Common Lisp.

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).

This a Common Lisp library to convert geographic coordinates between latitude/longitude and UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic).

This package provides a Common Lisp implementation of ActivityPub and ActivityStreams standards for social networking.

Features:

• Parsing and un-parsing ActivityStreams JSON-LD objects to/from CLOS objects with convenient accessors on those.

• Sending and fetching ActivityStreams objects to/from the ActivityStreams-enabled HTTP(S) URLs.

• Semantic info extraction with methods like name*, url*, author*, and published*.

• No reliance on JSON parser. njson is used for parser-independent JSON handling. Load the parser backend you prefer!

Smart-buffer provides an output buffer which changes the destination depending on content size.

DATA-SIFT is a Common Lisp data validation and transformation library inspired by cl-data-format-validation and WTForms validators.

This Common Lisp library provides bindings for the ZeroMQ lightweight messaging kernel.

This library provides payment API wrappers over BTCPay, Paypal, and Stripe.

This package provides functions for generating lorem ipsum text.
