This package provides a functionality augmenting Hunchentoot error pages and logs with request and session information.

This is a Common lisp library to unify access to the most common dictionary-like data structures.

This package provides a Common Lisp library for dice rolling and working with dice-roll statistics.

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 Common Lisp library provides function to make QR codes and to save them as PNG files.

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 library allows you to define custom indentation hints for your macros if the one recognised by SLIME automatically produces unwanted results.

This package provides a way of extracting and replicating the compile-time side-effects of forms.

fast-http is a HTTP request/response protocol parser for Common Lisp.

Simplified-Types is a library that provides functions for simplifying Common Lisp type specifiers. The API consists of two functions:

• simplify-type takes a type specifier and, optionally, an environment, and returns the corresponding simplified type.

• simplified-type-of takes an object and returns the simplified type of that object.

This Common Lisp library focuses on the small set of basic color manipulations (lightening, compliments, etc.) you might use to generate a color palette for a GUI or web page.

cl-numerical-utilities is a collection of packages useful in numerical applications, each big enough to be its own package, but too small to split out into a separate ASDF system.

This is a trivial utility for distinguishing between a process running in a real terminal window and a process running in a dumb one, e.g. emacs-slime.

This library provides a tiny Common Lisp wrapper around setlocale(3) and can be used in conjunction with other FFI wrappers like cl-charms.

Cluffer is a library for representing the buffer of a text editor. As such, it defines a set of CLOS protocols for client code to interact with the buffer contents in various ways, and it supplies different implementations of those protocols for different purposes.

This package provides an implementation of the flexichain protocol, allowing client code to dynamically add elements to, and delete elements from a sequence (or chain) of such elements.

DIFF is a package for computing various forms of differences between blobs of data and then doing neat things with those differences. Currently diff knows how to compute three common forms of differences: "unified" format diffs, "context" format diffs, and "vdelta" format binary diffs.

April compiles a subset of the APL programming language into Common Lisp. Leveraging Lisp's powerful macros and numeric processing faculties, it brings APL's expressive potential to bear for Lisp developers. Replace hundreds of lines of number-crunching code with a single line of APL.

This package provides a canonical way of converting generalized booleans to booleans.

This Common Lisp package offers an implementation of the 32-bit variant of MurmurHash3 (https://github.com/aappleby/smhasher), a fast non-crytographic hashing algorithm.

CL-PPCRE is a portable regular expression library for Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

Transducers are an ergonomic and extremely memory-efficient way to process a data source. Data source refers to simple collections like lists or vectors, but also potentially large files or generators of infinite data.

This library features a rectangle packer for sprite and texture atlases.

zsort is a collection of portable sorting algorithms. Common Lisp provides the sort and stable-sort functions but these can have different algorithms implemented according to each implementation. Also, the standard sorting functions might not be the best for a certain situations. This library aims to provide developers with more options.
