There are plenty of Lisp Markup Languages out there - every Lisp programmer seems to write at least one during his career - and CL-WHO (where WHO means "with-html-output" for want of a better acronym) is probably just as good or bad as the next one.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and MGRS.

Markup allows the use of HTML syntax with in Common Lisp code. This has the advantage of being able to copy HTML snippets and have them instantly be functional, less double quotes than a s-expression approach, and designers will be able to understand the embedded HTML.

This is a Common Lisp library for simplifying packaging and loading of compiled foreign library collection.

A Common Lisp client library for Apache Kafka.

mito-auth provides a mito mixin class for user authorization.

This package provides a Common Lisp bindings to glfw, an OpenGL application development library.

RESTAS is a Common Lisp web application framework.

This is a library for quaternions. It contains most of the quaternion operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable. It also tries to be efficient where plausible. Each quaternion is made up of floats, which by default are single-floats, as they do not require value boxing on most modern systems and compilers.

This is a Common Lisp library that publishes D-Bus objects as well as send and notify other objects connected to a bus.

This package provides matrix algebra functions for Common Lisp.

Portable Threads (and Scheduled and Periodic Functions) API for Common Lisp (from GBBopen project).

This package provides a standard interface to the various package lock implementations of Common Lisp.

This is a Common Lisp implementation for the Mustache template system. More details on the standard are available at https://mustache.github.io.

ASDF-FLV provides support for file-local variables through ASDF. A file-local variable behaves like *PACKAGE* and *READTABLE* with respect to LOAD and COMPILE-FILE: a new dynamic binding is created before processing the file, so that any modification to the variable becomes essentially file-local.

In order to make one or several variables file-local, use the macros SET-FILE-LOCAL-VARIABLE(S).

SLY is a fork of SLIME, an IDE backend for Common Lisp. It also features a completely redesigned REPL based on Emacs's own full-featured comint-mode, live code annotations, and a consistent interactive button interface. Everything can be copied to the REPL. One can create multiple inspectors with independent history.

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 is a Common Lisp implementation for the Mustache template system. More details on the standard are available at https://mustache.github.io.

This Common Lisp library provides string encoding and decoding routines for IDNA, the International Domain Names in Applications.

BORDEAUX-THREADS is a proposed standard for a minimal MP/Threading interface. It is similar to the CLIM-SYS threading and lock support.

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

This is a small OS portability library to retrieve and set file attributes not supported by the Common Lisp standard functions.

MAP-BIND is a macro that allows visual grouping of variables with their corresponding values in calls to mapping operators when using an inline LAMBDA.

This library retrieves locale information configured on the system. This is helpful if you want to write applications and libraries that display messages in the user's native language.
