TRIVIAL-TYPES provides missing but important type definitions such as PROPER-LIST, ASSOCIATION-LIST, PROPERTY-LIST and TUPLE.

Conium is a portability library for debugger- and compiler-related tasks in Common Lisp. It is fork of SWANK-BACKEND.

This package provides Common Lisp bindings to GSSAPI, which is designed to provide a standard API to authentication services. The API itself is generic, and the system can provide different underlying implementations. The most common one is Kerberos, which has several implementations, the most common of which is probably Active Directory.

Hunchenissr works together with issr.js for the development of interactive (changing without page refreshes) websites making use of websocket and Common Lisp server HTML generation instead of mountains of convoluted Javascript.

CL-MOUNT-INFO is a Common Lisp wrapper around getmntent(3) and related C functions to get information about the mounted file system.

This package provides a library to open a web browser to a URL.

This is a collection of common cryptography functions for Common Lisp.

CXML does an excellent job at parsing XML elements, but what do you do when you have a XML file that's larger than you want to fit in memory, and you want to extract some information from it? Writing code to deal with SAX events, or even using Klacks, quickly becomes tedious. cl-xmlspam (for XML Stream PAttern Matcher) is designed to make it easy to write code that mirrors the structure of the XML that it's parsing. It also makes it easy to shift paradigms when necessary - the usual Lisp control constructs can be used interchangeably with pattern matching, and the full power of CXML is available when necessary.

Provides a simple way of directing output to a stream according to the concise and intuitive semantics of FORMAT's stream argument.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and Maidenhead locator system.

This is a library to provide cross-platform access to gamepads, joysticks, and other such HID devices.

This is a Common Lisp library providing a set of macros for generating lexical analyzers automatically. The lexers generated using cl-lex can be used with cl-yacc.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.

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

This package creates GraphViz DOT files from an equivalent s-expression representation.

This is a collection of useful helper modules and standard implementations for Radiance interfaces.

cl-pass is a password hashing and verification library.

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

This package provides Common Lisp FFI bindings for libwayland, primarily for the mahogany window manager.

This package provides the CL-SVG Common Lisp system to produce Scalable Vector Graphics files.

This is a dead-simple, non validating, inline CSS generator for Common Lisp. Its goals are axiomatic syntax, simple implementation to support portability, and boilerplate reduction in CSS.

This package provides a safer variant of READ secure against internbombing, excessive input and macro characters.

Agnostic Lizard is a portable implementation of a code walker and in particular of the macroexpand-all function (and macro) that makes a best effort to be correct while not expecting much beyond what the Common Lisp standard requires.

It aims to be implementation-agnostic and to climb the syntax trees.

This library lets you build a metaclass which in turn lets you specify extra slot options in its classes. Options may be easily inspected and custom inheritance may be set up. The Meta-Object Protocol (MOP) is used for the implementation - through closer-mop. Some convenience function for processing slot options are also available.

Possible use case: you want to automatically set up some definitions based on some slots, but you want to have control over it right in the class definition.
