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).

Typo is a portable library for Common Lisp that does approximate reasoning about types, but without consing.

This package provides a JSON Pointer (RFC6901) implementation for Common Lisp. This library aims to be independent from any JSON libraries (as much as possible).

This package provides a concise, intuitive and flexible macro for trivial lambdas that eschews explicit naming of parameter variables in favor of positional references, with support for a used or ignored &rest parameter and automatic declaration of ignored parameters when logical gaps are left in the positional references. Further convenience features are provided.

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

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

This package provides Common Lisp extension to the MOP to allow abstract, final and singleton classes.

Generic documentation builder for Common Lisp projects.

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

Trivial Monitored Thread offers a very simple (aka trivial) way of spawning threads and being informed when one any of them crash and die.

This Common Lisp library provides a tiny utility to change the size of a simple-array ensuring that the resulting array is still a simple-array.

This library is a portable compatibility layer around "Common Lisp the Language, 2nd Edition" (https://www.cs.cmu.edu/Groups/AI/html/cltl/clm/node102.html) and it exports symbols from implementation-specific packages.

This is a library to find system font files. It works on systems with FontConfig on Linux, BSD. It does not have any foreign dependencies that aren't already directly available on the system.

DEFLATE data, defined in RFC1951, forms the core of popular compression formats such as zlib (RFC 1950) and gzip (RFC 1952). As such, Chipz also provides for decompressing data in those formats as well. BZIP2 is the format used by the popular compression tool bzip2.

This Common Lisp package offers functions for parsing and formatting decimal numbers. The package's main interface are the functions parse-decimal-number and format-decimal-number. The former is for parsing strings for decimal numbers and the latter for pretty-printing them as strings.

ARNESI is Common Lisp utilities library similar to ALEXANDRIA, ANAPHORA or GOLDEN-UTILS.

This is a Commin Lisp library for operating on permutations and permutation groups.

This package provides some condition classes, functions and macros which may be useful when building slightly complex systems.

This is a small library providing the ISO-639 language code to language name mapping.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

McCLIM is an implementation of the Common Lisp Interface Manager specification, a toolkit for writing GUIs in Common Lisp.

Funds provides portable, purely functional data structures in Common Lisp. It includes tree based implementations for Array, Hash, Queue, Stack, and Heap.

This package provides a SuperCollider client for Common Lisp.
