cl-annot is an general annotation library for Common Lisp.

cl-libxml2 is high-level Common Lisp wrapper around the libxml2 and libxslt libraries.

• Interfaces for tree manipulation (like cxml-stp).

• Interface for HTML 4.0 non-validating parsers.

• Specific APIs to process HTML trees, especially serialization.

• XPath API.

• XSLT API.

• Custom URL resolvers.

• XPath extension functions.

• XSLT extension elements.

• Translates libxml2 and libxslt errors to Lisp conditions.

• Extends the Common Lisp iterate library with custom drivers for child nodes enumeration, etc.

• The XFACTORY system provides a simple and compact syntax for XML generation.

This package provides the getopt function to parse command-line options. The options are organized in valid options, other arguments and unknown arguments. Optional Lisp conditions for error situations are also defined.

This package provides a Common Lisp ASDF system auto-loading extension.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

The 3d-math library implements types, operators, and algorithms commonly used in math for 2D and 3D graphics. It supersedes and combines the prior libraries 3d-vectors, 3d-matrices, 3d-quaternions, and 3d-transforms. The new API is largely but not entirely backwards compatible, and adds new functionality.

CMN provides a package of functions to hierarchically describe a musical score. When evaluated, the musical score is rendered to an image.

clsql is a Common Lisp interface to SQL RDBMS based on the Xanalys CommonSQL interface for Lispworks. It provides low-level database interfaces as well as a functional and an object oriented interface.

This package provides a flexible shallow/deep copy mechanism for Common Lisp.

This is a string/octets parser library for Common Lisp with speed and readability in mind. Unlike other libraries, the code is not a pattern-matching-like, but a char-by-char procedural parser.

Closer to MOP is a compatibility layer that rectifies many of the absent or incorrect CLOS MOP features across a broad range of Common Lisp implementations.

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.

The LOCAL-TIME library is a Common Lisp library for the manipulation of dates and times. It is based almost entirely upon Erik Naggum's paper "The Long Painful History of Time".

CXML implements a namespace-aware, validating XML 1.0 parser as well as the DOM Level 2 Core interfaces. Two parser interfaces are offered, one SAX-like, the other similar to StAX.

This package provides the CL-SVG Common Lisp system to produce Scalable Vector Graphics files.

Ironclad is a cryptography library written entirely in Common Lisp. It includes support for several popular ciphers, digests, MACs and public key cryptography algorithms. For several implementations that support Gray streams, support is included for convenient stream wrappers.

This package provides Common Lisp FFI bindings for libwayland, primarily for the mahogany window manager.

Chunga implements streams capable of chunked encoding on demand as defined in RFC 2616.

Domain specific language for producing TeX documents with Common Lisp.

Py4CL is a bridge between Common Lisp and Python, which enables Common Lisp to interact with Python code. It uses streams to communicate with a separate python process, the approach taken by cl4py. This is different to the CFFI approach used by burgled-batteries, but has the same goal.

cl-smug is a library for parsing text, based on monadic parser combinators. Using a simple technique from the functional programming camp, cl-smug makes it simple to create quick extensible recursive descent parsers without funky syntax or impenetrable macrology.

This is a library to find system font files. It works on systems with FontConfig on Linux, BSD. It does not have any foreign dependencies that aren't already directly available on the system.

Binary-types is a Common Lisp package for reading and writing binary files. Binary-types provides macros that are used to declare the mapping between Lisp objects and some binary (i.e. octet-based) representation.

Serapeum is a conservative library of Common Lisp utilities. It is a supplement, not a competitor, to Alexandria.
