Portable Threads (and Scheduled and Periodic Functions) API for Common Lisp (from GBBopen project).

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

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 package is a Python Numpy clone implemented in pure Common Lisp.

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 an implementation of a Markdown parser in Common Lisp.

This is a library that uses the other 3d-* math libraries to present an encapsulation for a spatial transformation. It offers convenience functions for operating on such transformations and for converting between them and the alternative 4x4 matrix representation.

These common lisp sources contain two variants of the Nelder-Mead algorithm. The original algorithm and a provably convergent, reliable variant by A. Bürmen et al, called the GRNMA.

An implementation of the exponential backoff algorithm in Common Lisp. Inspired by the implementation found in Chromium. Read the header file to learn about each of the parameters.

PARSER-COMBINATORS is a library implementing monadic parser combinators in Common Lisp, similar in concept to Haskell Parsec system.

This package provides an ASN.1 encoder/decoder for Common Lisp.

CL-SXML implements Oleg Kiselyov’s SXML, an S-expression-based rendering of the XML Infoset.

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

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

dbi is a Common Lisp library providing a database independent interface for MySQL, PostgreSQL and SQLite.

Clack is a web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack.

cl-webkit is a binding to WebKitGTK+ for Common Lisp, currently targeting WebKit version 2. The WebKitGTK+ library adds web browsing capabilities to an application, leveraging the full power of the WebKit browsing engine.

CLOBBER is an alternative to so-called object prevalence, and in particular to cl-prevalence. Clobber is both simpler, more flexible, and more robust than systems based on object prevalence.

This is a binding to the libyaml library. It's not meant as a full library for YAML, just a bare binding with a couple of utility macros. For a YAML parser and emitter using this, check out cl-yaml.

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

GENERIC-COMPARABILITY is an implementation of CDR-8 (Generic Equality and Comparison for Common Lisp). CDR-8 provides an interface for the EQUALS function, which is defined as a general equality predicate, as well as a set of ordering (COMPARE) functions for comparison. The semantics are described in the CDR-8 standard.

This Common Lisp package offers functions for parsing and formatting decimal numbers. The package's main interface are the functions parse-decimal-number and format-decimal-number. The former is for parsing strings for decimal numbers and the latter for pretty-printing them as strings.

This package provides a Common Lisp system which has only one function to return the CPU count of the current system.

fare-utils is a small collection of utilities. It contains a lot of basic everyday functions and macros.
