This package provides a Common Lisp implementation of Base64 encoding and decoding. Base64 encoding is a technique to encode binary data in a portable, safe printable, 7-bit ASCII format.

This Common Lisp library provides reader macros for concise expression of function partial application and composition.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and Maidenhead locator system.

This is a general Freetype 2 wrapper for Common Lisp using CFFI. It's geared toward both using Freetype directly by providing a simplified API, as well as providing access to the underlying C structures and functions for use with other libraries which may also use Freetype.

This package makes it possible to name classes by lists of symbols instead of symbols.

This Common Lisp library implements a parser generator for the ABNF grammar format as described in RFC2234. The generated parser is a regular expression scanner provided by the cl-ppcre lib, which means that we can't parse recursive grammar definition. One such definition is the ABNF definition as given by the RFC. Fortunately, as you have this lib, you most probably don't need to generate another parser to handle that particular ABNF grammar.

Clavier is a general purpose validation library for Common Lisp.

Simple color library for Common Lisp.

This package provides CFFI binding to libmixed audio library for Common Lisp with support of other audio formats available on GNU/Linux systems:

• Alsa

• Jack

• Openmpt

• PulseAudio

• Flac (via CL-FLAC)

• Mpg123 (via CL-MPG123)

• Ogg/vorbis (via CL-VORBIS)

• Out123 (via CL-OUT123)

• WAV

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

This package provides a Common Lisp web framework for building GUI applications. CLOG can take the place, or work along side, most cross platform GUI frameworks and website frameworks. The CLOG package starts up the connectivity to the browser or other websocket client (often a browser embedded in a native template application).

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.

This library can be used to display a progress bar on one line.

This library generates sdf (https://steamcdn-a.akamaihd.net/apps/valve/2007/SIGGRAPH2007_AlphaTestedMagnification.pdf), psdf and msdf (https://github.com/Chlumsky/msdfgen/files/3050967/thesis.pdf) atlases.

Varjo is a Lisp to GLSL compiler. Vari is the dialect of lisp Varjo compiles. It aims to be as close to Common Lisp as possible, but naturally it is statically typed so there are differences.

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

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.

Funds provides portable, purely functional data structures in Common Lisp. It includes tree based implementations for Array, Hash, Queue, Stack, and Heap.

This package provides a canonical way of converting class designators to classes.

Alexandria is a collection of portable utilities. It does not contain conceptual extensions to Common Lisp. It is conservative in scope, and portable between implementations.

jzon is a correct and safe JSON RFC 8259 parser for Common Lisp.

This package provides a SuperCollider client for Common Lisp.

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.

FSet is a functional set-theoretic collections library for Common Lisp. Functional means that all update operations return a new collection rather than modifying an existing one in place. Set-theoretic means that collections may be nested arbitrarily with no additional programmer effort; for instance, sets may contain sets, maps may be keyed by sets, etc.
