Napa-FFT3 provides Discrete Fourier Transform (DFT) routines, but also buildings blocks to express common operations that involve DFTs: filtering, convolutions, etc.

This package provides supports for unicode normalization, RFC8264 and RFC7564.

Moira is a library for monitoring and, if necessary, restarting long-running threads. In principle, it is like an in-Lisp process supervisor.

This is a utility kit for cl-sdl2 that provides something similar to GLUT. However, it's also geared at being useful for "real" applications or games.

This package defines a simple extensible protocol for computing a guess using advisors.

A client for the Stripe payment API.

This is a Common Lisp library for reading and printing MIME content. It supports automatic conversion between 7-bit, quoted-printable and base64 encodings.

This is only useful if you want to start a Swank server in a Lisp processes that doesn't run under Emacs. Lisp processes created by M-x slime automatically start the server.

Chunga implements streams capable of chunked encoding on demand as defined in RFC 2616.

40ants-plantuml provides a wrapper around the PlantUML jar library.

Prometheus.io Common Lisp client.

It can sometimes be useful to be able to parse chemical compounds in a user-friendly syntax into easy-to-manipulate s-expressions. You also want to be able to go in reverse. You could probably write your own parser — or you could just install the chemical-compounds package.

This library is an implementation of the XML Path Language (XPath) Version 1.0.

This package provides a pure-lisp implementation of a DNS client. It can be used to resolve hostnames, reverse-lookup IP addresses, and fetch other kinds of DNS records.

3bz is an implementation of Deflate decompression (RFC 1951) optionally with zlib (RFC 1950) or gzip (RFC 1952) wrappers, with support for reading from foreign pointers (for use with mmap and similar, etc), and from CL octet vectors and streams.

simple-routes is a simple Common Lisp RESTful routing facility on top of Hunchentoot.

This is a Common Lisp library providing various utilities.

This package holds an enhanced implementation of hooks (extension points). It works similarly to Emacs hooks with crucial improvements:

• If the compiler allows it (such as SBCL), type-checking is performed at compile-time and at run-time when adding handlers to a hook.

• On failure, multiple restarts are offered, such as disabling the offending handler or simply continuing to the next function.

• The hook handler execution order and combination can be customized.

• Anonymous functions (lambdas) can be added to hooks as handler objects. When inspecting hooks, readable names are thus exposed instead of lambda blackboxes. Handlers are compared through their names (through the mandatory name slot). A hook can not contain multiple handlers with the same name.

• A special provision is taken for “setters”, handlers that are meant to set a given place to a given values. Such handler objects can be compared and identified uniquely.

This is a portable Universal Resource Identifier library for Common Lisp programs. It parses URI according to the RFC 2396 specification.

This package provides a Common Lisp implementation of the semantic versioning specification: http://semver.org.

This package provides Common Lisp FFI bindings for xkbcommon (libxkbcommon) using cffi-grovel.

This is a Common Lisp library to calculate std140 or std430 layouts for a glsl UBO/SSBO.

cl-rucksack is a persistence library based on Arthur Lemmens' Rucksack with some enhancements.

A heap-based priority queue whose first and foremost priority is speed.
