FLOW is a flowchart graph library. Unlike other graphing libraries, this one focuses on nodes in a graph having distinct ports through which connections to other nodes are formed. This helps in many concrete scenarios where it is important to distinguish not only which nodes are connected, but also how they are connected to each other.

Particularly, a lot of data flow and exchange problems can be reduced to such a flowchart. For example, an audio processing library may present its pipeline as a flowchart of segments that communicate with each other through audio sample buffers. Flow gives a convenient view onto this kind of problem, and even allows the generic visualisation of graphs in this format.

This is a task scheduling framework for Common Lisp.

trivial-garbage provides a portable API to finalizers, weak hash-tables and weak pointers on all major implementations of the Common Lisp programming language.

This package provides a DSL for array slices in Common Lisp.

This library contains a lexer for syntaxes that use shell-like rules for quoting and commenting. It is a port of the shlex module from Python’s standard library.

This Common Lisp library provides a simple FIFO implementation with no external dependencies.

LTK is a Common Lisp binding for the Tk graphics toolkit. It is written in pure Common Lisp and does not require any Tk knowledge for its usage.

This library builds on the venerable idea of dynamically memoizing functions. A memoized function remembers results from previous computations and returns cached results when called again with the same arguments rather than repeating the computation.

This is a very short and simple program, written in Common Lisp, that extends Common Lisp to embed shell code in a manner similar to Perl's backtick. It has been forked from SHELISP.

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

This library provides an asynchronous process execution mechanism for Common Lisp.

This Common Lisp library provides an implementation of in-memory input streams, output streams and io streams for any type of elements.

A dataflow extension to Common Lisp that maintains a consistent state of cells according to functions specifying their relation.

Dufy is a library for exact color manipulation and conversion in various color spaces, which supports many color models.

This is a lisp implementation of the Open Sound Control protocol (or more accurately “data transport specification” or “encoding”). The code should be close to ANSI standard common lisp and provides self contained code for encoding and decoding of OSC data, messages, and bundles.

This package provides a simple yet powerful value inheritance scheme.

This is a Common Lisp library to handle the IBM PC version of the IXF (Integration Exchange Format) file format.

Simple scheme to classify file types in a hierarchical fashion.

A Common Lisp library for computing differences between sequences based on the Python difflib module.

cl-dotenv is a utility library for loading .env files in Common Lisp.

This package provides a functionality augmenting Hunchentoot error pages and logs with request and session information.

This is an implementation of a Markdown parser in Common Lisp.

This package provides a Common Lisp system with a collection of common tests and operations to help handling pathnames. It does not actually deal in handling the accessing of files on the underlying system however.

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