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.

bubble-operator-upwards is a function that bubbles an operator upwards in a form, demultiplexing all alternative branches by way of cartesian product.

This is a library for representing and mapping colours between their various spaces.

This package allows flexible specification of package-local preferences.

YASON is a Common Lisp library for encoding and decoding data in the JSON interchange format.

doplus is an iteration macro for Common Lisp.

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.

simple-optimization is a Common Lisp library providing a function to solve unconstrained optimization problems numerically using either the gradient descent or a quasi-Newton method.

This is a simple extension to MODULARIZE that allows modules to define and trigger hooks, which other modules can hook on to.

XSubseq provides functions to be able to handle "subseq"s more effieiently.

This library provides functions for determining the value types of Common Lisp forms, based on type information contained in the environment.

In order for this library to work the values types of variables and return types of functions have to be declared.

Macros and symbol-macros are fully expanded and all special forms, except CATCH, are supported.

This library is a collection of pseudo random number generators.

While Common Lisp does provide a RANDOM function, it does not allow the user to pass an explicit SEED, nor to portably exchange the random state between implementations. This can be a headache in cases like games, where a controlled seeding process can be very useful.

For both curiosity and convenience, this library offers multiple algorithms to generate random numbers, as well as a bunch of generally useful methods to produce desired ranges.

This package provides functions for generating lorem ipsum text.

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.

CLACHE provides a general caching facility for Common Lisp. The API is similar to the standard hash-table interface.

VAS-STRING-METRICS provides the Jaro, Jaro-Winkler, Soerensen-Dice, Levenshtein, and normalized Levenshtein string distance/similarity metrics algorithms.

This package provides a macro that allows foreign functions to access the contents of the array at a given pointer, using the best available method given the Common Lisp implementation.

This is ZS3, a library for working with Amazon's Simple Storage Service (S3) and CloudFront service from Common Lisp.

This package provides a Common Lisp Twitter client featuring full API coverage.

A Common Lisp client library for Apache Kafka.

LLA is a high-level Common Lisp library built on BLAS and LAPACK, but providing a much more abstract interface with the purpose of freeing the user from low-level concerns and reducing the number of bugs in numerical code.

This package provides Common Lisp FFI bindings for xkbcommon (libxkbcommon) using cffi-grovel.

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 is a Common Lisp library for solving linear programming problems.
