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 library provides arbitrary precision (floating point) real numbers in Common Lisp.

cl-cookie is a Common Lisp library featuring parsing of cookie headers, cookie creation, cookie jar creation and more.

Croatoan provides high-level Common Lisp CLOS bindings for the ncurses terminal library.

jzon is a correct and safe JSON RFC 8259 parser for Common Lisp.

This is a Common Lisp library which provides functionality to read/write Bit Map Font (BMF) into text, JSON and XML.

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

This package provides a macro that allows foreign functions to access the contents of the array at a given pointer, using the best available method given the Common Lisp implementation.

This library contains generic hacks meant to be used in any project. It was originally developed for the Cells library.

Command line interface (CLI) that wraps Common Lisp ASDF (Common Lisp build system) and Common Lisp quickproject for building and creating new Common Lisp (ASDF) projects from the command line.

cl-alexandria-plus is a conservative set of extensions to cl-alexandria utilities.

This package provides a Common Lisp implementation of Google Closure Templates.

This package provides the getopt function to parse command-line options. The options are organized in valid options, other arguments and unknown arguments. Optional Lisp conditions for error situations are also defined.

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

Montezuma is a text search engine library for Lisp based on the Ferret library for Ruby, which is itself based on the Lucene library for Java.

This is a Common Lisp library to load images in the PNG image format, both from files on disk, or streams in memory.

This package provides a Common Lisp wrapper system for the SDL 2.0 C Library.

This package provides a Common Lisp library to work with the JSON file format.

This Common Lisp library provides optimized byte-swapping primitives. The library can change endianness of unsigned integers of length 1/2/4/8. Very useful in implementing various network protocols and file formats.

CLX is an X11 client library for Common Lisp. The code was originally taken from a CMUCL distribution, was modified somewhat in order to make it compile and run under SBCL, then a selection of patches were added from other CLXes around the net.

This library provides all of

• ad hoc polymorphism and

• subtype polymorphism

• parametric polymorphism (in a very limited sense)

to dispatch on the basis of types rather than classes.

This library is an extension of the Common Lisp Object System (CLOS) that allows a compiler to inline a generic function under certain conditions.

This package provides a macro commonly used in livecoding to enable continuing when errors are raised. Simply wrap around a chunk of code and it provides a restart called continue which ignores the error and carrys on from the end of the body.

trivial-clipboard gives access to the system clipboard.
