This system is an implementation of the Common Lisp type system; particularly cl:typep and cl:subtypep.

This package provides Common Lisp bindings to the pango text layout library.

Flexi-streams is an implementation of "virtual" bivalent streams that can be layered atop real binary or bivalent streams and that can be used to read and write character data in various single- or multi-octet encodings which can be changed on the fly. It also supplies in-memory binary streams which are similar to string streams.

CL-SXML implements Oleg Kiselyov’s SXML, an S-expression-based rendering of the XML Infoset.

This library provides a macroexpand-all function that calls the implementation specific equivalent.

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.

The purpose of this library is to provide a collection of implementations of trees.

In contrast to existing libraries such as cl-containers, it does not impose a particular use for the trees. Instead, it aims for a stratified design, allowing client code to choose between different levels of abstraction.

As a consequence of this policy, low-level interfaces are provided where the concrete representation is exposed, but also high level interfaces where the trees can be used as search trees or as trees that represent sequences of objects.

This library provides GTK4 bindings for Common Lisp via Gobject Introspection, in the cl-gtk4 ASDF system.

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.

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

This package provides a common lisp CFFI wrapper for the SciPy version of Cephes special functions.

Flexi-streams is an implementation of "virtual" bivalent streams that can be layered atop real binary or bivalent streams and that can be used to read and write character data in various single- or multi-octet encodings which can be changed on the fly. It also supplies in-memory binary streams which are similar to string streams.

CL-Yacc is a LALR(1) parser generator for Common Lisp, similar in spirit to AT&T Yacc, Berkeley Yacc, GNU Bison, Zebu, lalr.cl or lalr.scm.

CL-Yacc uses the algorithm due to Aho and Ullman, which is the one also used by AT&T Yacc, Berkeley Yacc and Zebu. It does not use the faster algorithm due to DeRemer and Pennello, which is used by Bison and lalr.scm (not lalr.cl).

This library is a collection of functions and macros for manipulating Common Lisp arrays and performing numerical calculations with them.

This is a Common Lisp library to extract EXIF information from image files.

This package provides CFFI bindings to convert between different character encodings using iconv.

A simple Common-Lisp interface to the underlying operating system. It's independent of the implementation and operating system.

This is a Common Lisp library to enable simple message pipelines.

UBIQUITOUS is a very easy-to-use library for persistent configuration storage. It automatically takes care of finding a suitable place to save your data, and provides simple functions to access and modify the data within.

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

This library implements efficient algorithms that calculate various string metrics in Common Lisp:

• Damerau-Levenshtein distance

• Hamming distance

• Jaccard similarity coefficient

• Jaro distance

• Jaro-Winkler distance

• Levenshtein distance

• Normalized Damerau-Levenshtein distance

• Normalized Levenshtein distance

• Overlap coefficient

Simple library to create temporary directories.

This package provides the Common Lisp HTTP server WOO, which is built on top of the libev event library.

This is a Common Lisp utilities library originating from the Zombie Raptor game engine project.
