Enchant is a Common Lisp interface for the Enchant spell-checker library. The Enchant library is a generic spell-checker library which uses other spell-checkers transparently as back-end. The library supports the multiple checkers, including Aspell and Hunspell.

This library is an extension of the Common Lisp Object System (CLOS) that allows a compiler to inline a generic function under certain conditions.

Splits sequence into a list of subsequences delimited by objects satisfying the test.

This is a Common Lisp library for reading PNG images.

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 shim between Python3 (specifically, the CPython implementation of Python) and Common Lisp.

Loop has a consistent interface unlike other looping abstractions and ANSI list operations. You can define your own efters and gatherers that integrate tightly into other operations. All operations are non-consing when possible.

This package holds an enhanced implementation of hooks (extension points). It works similarly to Emacs hooks with crucial improvements:

• If the compiler allows it (such as SBCL), type-checking is performed at compile-time and at run-time when adding handlers to a hook.

• On failure, multiple restarts are offered, such as disabling the offending handler or simply continuing to the next function.

• The hook handler execution order and combination can be customized.

• Anonymous functions (lambdas) can be added to hooks as handler objects. When inspecting hooks, readable names are thus exposed instead of lambda blackboxes. Handlers are compared through their names (through the mandatory name slot). A hook can not contain multiple handlers with the same name.

• A special provision is taken for “setters”, handlers that are meant to set a given place to a given values. Such handler objects can be compared and identified uniquely.

This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.

This Common Lisp library implements a parser generator for the ABNF grammar format as described in RFC2234. The generated parser is a regular expression scanner provided by the cl-ppcre lib, which means that we can't parse recursive grammar definition. One such definition is the ABNF definition as given by the RFC. Fortunately, as you have this lib, you most probably don't need to generate another parser to handle that particular ABNF grammar.

MT19937 is a portable Mersenne Twister pseudo-random number generator for Common Lisp.

This is a library for reading semi-raw user input from terminals. Semi-raw as in, we can't detect if the user pressed the Control key alone, and the function keys are a mystery. What is supported, however, is:

• Regular characters

• Control+[key]

• Alt+[key]

• Control+Alt+[key]

This package provides Common Lisp extension to the MOP to allow abstract, final and singleton classes.

Linedit is a readline-style library written in Common Lisp that provides customizable line-editing for Common Lisp programs.

This is a Common Lisp library providing RFC 3986 percent-encoding.

File-Notify is a Common Lisp library for getting notifications for file accesses and changes.

The variates package provides portable random number generation as well as numerous distributions.

This package provides a SuperCollider client for Common Lisp.

Plump is a parser for HTML/XML-like documents, focusing on being lenient towards invalid markup. It can handle things like invalid attributes, bad closing tag order, unencoded entities, inexistent tag types, self-closing tags and so on. It parses documents to a class representation and offers a small set of DOM functions to manipulate it. It can be extended to parse to your own classes.

HARMONY is a library that provides you with audio processing tools as well as an audio server to play back music, sfx, and so forth. It is most suited for use in a game engine, but may feasibly also be used for more advanced things such as a DAW

This is a system presenting a protocol for "file systems": things that present a collection of "files," which are things that have several attributes, and a central data payload. Most notably this includes the OS filesystem, but can also be used to address other filesystem-like things like archives, object stores, etc. in the same manner.

Birch is a simple Common Lisp IRC client library. It makes use of CLOS for event handling.

This is a Common Lisp library implementing the full v1 REST API protocol for Mastodon.

Spatial-trees is a set of dynamic index data structures for spatially-extended data.
