Parse-js is a Common Lisp package for parsing JavaScript (ECMAScript 3). It has basic support for ECMAScript 5.

This is futures implementation for Common Lisp. It plugs in nicely to cl-async.

This Common Lisp library contains the core classes and pixel access macros for the Opticl image processing library.

This is a small library providing the ISO-639 language code to language name mapping.

Utility library for handling bit vectors, bit vector arithmetic, and universal integer type conversions between bit-vectors, byte-vectors, octals, decimals, and hexadecimal notation.

Montezuma is a text search engine library for Lisp based on the Ferret library for Ruby, which is itself based on the Lucene library for Java.

HTML-TEMPLATE is a Common Lisp library which can be used to fill templates with arbitrary (string) values at runtime. The result does not have to be HTML.

It is loosely modeled after the Perl module HTML::Template and partially compatible with a its syntax, though both libraries contain some extensions that the other does not support.

HTML-TEMPLATE translates templates into efficient closures which can be re-used as often as needed. It uses a cache mechanism so you can update templates while your program is running and have the changes take effect immediately.

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 Common Lisp library provides string encoding and decoding routines for IDNA, the International Domain Names in Applications.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

This package provides an implementation of a base 16 builder for Common Lisp.

ASDF-FLV provides support for file-local variables through ASDF. A file-local variable behaves like *PACKAGE* and *READTABLE* with respect to LOAD and COMPILE-FILE: a new dynamic binding is created before processing the file, so that any modification to the variable becomes essentially file-local.

In order to make one or several variables file-local, use the macros SET-FILE-LOCAL-VARIABLE(S).

The purpose of this library is to provide a collection of implementations of trees.

In contrast to existing libraries such as cl-containers, it does not impose a particular use for the trees. Instead, it aims for a stratified design, allowing client code to choose between different levels of abstraction.

As a consequence of this policy, low-level interfaces are provided where the concrete representation is exposed, but also high level interfaces where the trees can be used as search trees or as trees that represent sequences of objects.

This is a Common Lisp library to extract EXIF information from image files.

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

This package provides a PNG Common Lisp system to operate with Portable Network Graphics file format.

DEFPACKAGE-PLUS is an extensible DEFPACKAGE variant with predictable cross-platform behavior and some utilities useful for versioning.

The GRAPH Common Lisp library provides a data structures to represent graphs, as well as some graph manipulation and analysis algorithms (shortest path, maximum flow, minimum spanning tree, etc.).

This library provides arbitrary precision (floating point) real numbers in Common Lisp.

This a Common Lisp library for reading and writing binary data. It is based on code from chapter 24 of the book Practical Common Lisp.

BST is a Common Lisp library for working with binary search trees that can contain any kind of values.

This package defines a Common Lisp package, :elements, with an ELEMENT structure and a number of functions to search the periodic table.

This is a wrapper for the SDL2_TTF library used for loading fonts and creating text assets. The library, in it's current state, can load TTF and OTF fonts and render fonts with the three different rendering modes provided by the C library (solid, shaded, and blended). While Latin text, UTF8, UNICODE, and Glyph text rendering is available only Latin text has been tested (as shown in the examples).
