This package provides a CONSPACK implementation for Common Lisp.

CL-FTP is a library which provides FTP client functionality to a Common Lisp program. CL-FTP uses the USOCKET package for network sockets and the SPLIT-SEQUENCE package for some parsing needs.

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

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

Clamp is an attempt to bring the powerful, but verbose, language of Common Lisp up to the terseness of Arc.

There are two parts to Clamp. There is the core of Clamp, which implements the utilities of Arc that are easily converted from Arc to Common Lisp. The other part is the "experimental" part. It contains features of Arc that are not so easy to copy (ssyntax, argument destructuring, etc.).

Arrow-macros provides clojure-like arrow macros (ex. ->, ->>) and diamond wands in swiss-arrows.

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.

This package provides a macro commonly used in livecoding to enable continuing when errors are raised. Simply wrap around a chunk of code and it provides a restart called continue which ignores the error and carrys on from the end of the body.

This is a Common Lisp macro for defining temporary caches that invalidate based on expressions evaluating to different values.

This package implements an algorithm for the spelling of enharmonics and dealing with ties and dots in rhythm notation.

This is an extension library to pathname-utils, to allow dealing with common problems with filesystems, such as listing files, probing file types, determining default directories, etc.

CLSS is a DOM traversal engine based on CSS selectors. It makes use of the Plump-DOM and is used by lQuery.

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

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

F2cl is a Common Lisp library that can convert Fortran 77 code into Common Lisp code.

A utility for running external programs, built on UIOP. Cmd is designed to be natural to use, protect against shell interpolation and be usable from multi-threaded programs.

This Common Lisp package contains the core math utilities of the Bodge library collection.

On Cliki.net <http://www.cliki.net/Common%20Lisp%20Utilities>, there is a collection of Common Lisp Utilities, things that everybody writes since they're not part of the official standard. There are some very useful things there; the only problems are that they aren't implemented as well as you'd like (some aren't implemented at all) and they aren't conveniently packaged and maintained. It takes quite a bit of work to carefully implement utilities for common use, commented and documented, with error checking placed everywhere some dumb user might make a mistake.

This package provides a grab bag of miscellaneous Common Lisp utilities.

FARE-MOP is a small collection of utilities using the MetaObject Protocol. It notably contains a SIMPLE-PRINT-OBJECT method, and a SIMPLE-PRINT-OBJECT-MIXIN mixin that allow you to trivially define PRINT-OBJECT methods that print the interesting slots in your objects, which is great for REPL interaction and debugging.

CL-ANA is a data analysis library in Common Lisp providing tabular and binned data analysis along with nonlinear least squares fitting and visualization.

This Common Lisp library provides optimized byte-swapping primitives. The library can change endianness of unsigned integers of length 1/2/4/8. Very useful in implementing various network protocols and file formats.

3D-VECTORS is a library for vector math in 3D space. It contains most of the vector operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable.

This package provides a way of extracting and replicating the compile-time side-effects of forms.
