Common Lisp port of Clojure's instaparse parser library - GLL parsing with EBNF/ABNF support.

This is a bare-bones Permuted Congruential Generator implementation in pure Common Lisp.

This package provides audio input and output functions to Common Lisp using bindings to the portaudio library.

This is a Common Lisp implementation of the Encoding for Robust Immutable Storage specification (ERIS).

atomichron is a Common Lisp library which implements a time meter which tracks how many times a form is evaluated, and how long evaluation takes. It uses atomic instructions so that meters will present correct results in the presence of multiple threads, while trying to minimize synchronization latency.

CL-FastCGI is a generic version of SB-FastCGI, targeting to run on mostly Common Lisp implementation.

This is a system for two dimensional computational geometry for Common Lisp.

Note: the system assumes exact rational arithmetic, so no floating point coordinates are allowed. This is not checked when creating geometric objects.

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

This library is intended to solve the problem of source tracking for Common Lisp code.

By "source tracking", it is meant that code elements that have a known origin in the form of a position in a file or in an editor buffer are associated with some kind of information about this origin.

Since the exact nature of such origin information depends on the Common Lisp implementation and the purpose of wanting to track that origin, the library does not impose a particular structure of this information. Instead, it provides utilities for manipulating source code in the form of what is called concrete syntax trees (CSTs for short) that preserve this information about the origin.

Common Lisp already has major 2 namespaces, function namespace and value namespace (or variable namespace), but there are actually more — e.g., class namespace. This library offers macros to deal with symbols from any namespace.

This package provides prototype Common Lisp implementations of TLS, RFC5246, ASN.1, x501,509, and PKCS1,3,5,8.

Cells is a mature, stable extension to CLOS allowing one to create classes whose instances can have slot values determined by instance-specific formulas.

Metatilities-base is the core of the metatilities Common Lisp library which implements a set of utilities.

PARSE is a simple token parsing library for Common Lisp.

Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to as CLIM and Iterate.

This package provides a Common Lisp implementation of Google Closure Templates.

Cells is a mature, stable extension to CLOS allowing one to create classes whose instances can have slot values determined by instance-specific formulas.

The Common Foreign Function Interface (CFFI) purports to be a portable foreign function interface for Common Lisp. The CFFI library is composed of a Lisp-implementation-specific backend in the CFFI-SYS package, and a portable frontend in the CFFI package.

Prometheus.io Common Lisp client.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

Bobbin is a simple word-wrapping library for strings in Common Lisp. It aims to be simple, work nicely for the majority of cases, and degrade gracefully for edge cases. It is not particularly concerned with speed — if you need very high-performance word wrapping, Bobbin is not for you.

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

Trivial-features ensures that *FEATURES* is consistent across multiple Common Lisp implementations.

Simple and fast marshalling of Lisp datastructures. Convert any object into a string representation, put it on a stream an revive it from there. Only minimal changes required to make your CLOS objects serializable.
