This is a binding to the libyaml library. It's not meant as a full library for YAML, just a bare binding with a couple of utility macros. For a YAML parser and emitter using this, check out cl-yaml.

CL-DEBUG provides a unified way to enable or disable debug-specific code. Debugging code can be enabled or disabled relative to program features denoted by either a symbol or a keyword.

cl-gserver is a 'message passing' library / framework with actors similar to Erlang or Akka. It supports creating reactive systems for parallel computing and event based message handling.

This package implements a simple interface for using WebSockets via Common Lisp.

Collections of accessor functions and patterns to access the elements in compound type specifier, e.g. dimensions in (array element-type dimensions)

This package provides a Common Lisp web framework for building GUI applications. CLOG can take the place, or work along side, most cross platform GUI frameworks and website frameworks. The CLOG package starts up the connectivity to the browser or other websocket client (often a browser embedded in a native template application).

Dissect is a small Common Lisp library for introspecting the call stack and active restarts.

CIEL is a ready-to-use collection of libraries providing: a binary, to run CIEL scripts; a simple full-featured REPL for the terminal; a Lisp library and a core image.

This package is a geospatial library, based on cl-wkb, that implements the OGC Well-Known Binary geographic geometry data model with PostGIS 3d, 4d extensions, and provides WKB and EWKB encoding and decoding functionality.

This package provides CFFI bindings for Common Lisp to the Cairo C library.

NClasses provides helper macros to help write classes, conditions, generic functions, and CLOS code in general with less boilerplate.

It's a fork of hu.dwim.defclass-star. It includes some bug fixes and extra features like type inference.

This package provides an implementation of a base 16 builder for Common Lisp.

CLOBBER is an alternative to so-called object prevalence, and in particular to cl-prevalence. Clobber is both simpler, more flexible, and more robust than systems based on object prevalence.

This package provides a client for SMTP.

RE is a small, portable, lightweight, and quick, regular expression library for Common Lisp. It is a non-recursive, backtracing VM.

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

This package provides CFFI bindings to the ASSIMP library for Common Lisp.

CL-PDF is a cross-platform Common Lisp library for generating PDF files.

Duologue is high-level interaction library for Common Lisp. It features coloured printing via cl-ansi-text and readline completion.

Common Lisp ships with a set of powerful built in data structures including the venerable list, full featured arrays, and hash-tables. CL-containers enhances and builds on these structures by adding containers that are not available in native Lisp (for example: binary search trees, red-black trees, sparse arrays and so on), and by providing a standard interface so that they are simpler to use and so that changing design decisions becomes significantly easier.

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

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

This library implements a basic promise datastructure, which is useful for dealing with asynchronous behaviours. Importantly, this library does not use any other libraries or frameworks, and instead leaves the execution and state transition of promise objects in your control, making it easy to integrate.

cl-annot is an general annotation library for Common Lisp.
