This Common Lisp library provides macros to access foreign memory.

Babel is a charset encoding and decoding library, not unlike GNU libiconv, but completely written in Common Lisp.

This package provides a canonical way of converting class designators to classes.

CL-Ledger is a Common Lisp port of the Ledger double-entry accounting system.

This package provides a standard way to canonicalize slot values.

This library validates superclasses according to a simple substitution model, thereby greatly simplifying the definition of class mixins.

This is a Common Lisp library to change the capitalization and spacing of a string or a symbol. It can convert to and from Lisp, english, underscore and camel-case rules.

This package provides a Common Lisp implementation of the semantic versioning specification: http://semver.org.

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

This package provides functions for base32 encoding and decoding as defined in RFC4648.

cl-pass is a password hashing and verification library.

Cluster is an assembler (initially for x86 and x86-64) with a difference. To avoid the issue of defining a syntax, the input to Cluster is a list of standard objects (i.e., instances of the class STANDARD-OBJECT), as opposed to a character file or S-expressions.

S-XML is a simple XML parser implemented in Common Lisp. This XML parser implementation has the following features:

• It works (handling many common XML usages).

• It is very small (the core is about 700 lines of code, including comments and whitespace).

• It has a core API that is simple, efficient and pure functional, much like that from SSAX (see also http://ssax.sourceforge.net).

• It supports different DOM models: an XSML-based one, an LXML-based one and a classic xml-element struct based one.

• It is reasonably time and space efficient (internally avoiding garbage generatation as much as possible).

• It does support CDATA.

• It should support the same character sets as your Common Lisp implementation.

• It does support XML name spaces.

This XML parser implementation has the following limitations:

• It does not support any special tags (like processing instructions).

• It is not validating, even skips DTD's all together.

Alexandria is a collection of portable utilities. It does not contain conceptual extensions to Common Lisp. It is conservative in scope, and portable between implementations.

This is a bindings library to libout123 which allows easy cross-platform audio playback.

THE-COST-OF-NOTHING is a library for measuring the run time of Common Lisp code. It provides macros and functions for accurate benchmarking and lightweight monitoring. Furthermore, it provides predefined benchmarks to determine the cost of certain actions on a given platform and implementation.

This software provides an interface by which Common Lisp programs can access lexicographic data from WordNet.

CLAWK is an AWK implementation embedded into Common Lisp.

cl-xkb is a Common Lisp wrapper for the libxkbcommon keyboard handling library.

The library currently supports these xkb modules:

• Keysyms

• Library Context

• Include Paths

• Logging Handling

• Keymap Creation

• Keymap Components

• Keyboard State

• Compose and dead-keys support

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 library is a small interface to portable but nonstandard introspection of Common Lisp environments. It is intended to allow a bit more compile-time introspection of environments in Common Lisp.

Quite a bit of information is available at the time a macro or compiler-macro runs; inlining info, type declarations, that sort of thing. This information is all standard - any Common Lisp program can (declare (integer x)) and such.

This info ought to be accessible through the standard &environment parameters, but it is not. Several implementations keep the information for their own purposes but do not make it available to user programs, because there is no standard mechanism to do so.

This library uses implementation-specific hooks to make information available to users. This is currently supported on SBCL, CCL, and CMUCL. Other implementations have implementations of the functions that do as much as they can and/or provide reasonable defaults.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

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 Common Lisp library provides a tiny utility to change the size of a simple-array ensuring that the resulting array is still a simple-array.
