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

Trivial-features ensures that *FEATURES* is consistent across multiple Common Lisp implementations.

This library enables path variables in networking routes when using Hunchenissr for Common Lisp. If a part of the path (between two slashes) starts with a question mark (?), that symbol (without question mark) will be bound to whatever value was in the same place in the URL (as a string).

A library and command line utility to automatically indent Common Lisp source files.

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

A heap-based priority queue whose first and foremost priority is speed.

trivial-clipboard gives access to the system clipboard.

This is a string/octets parser library for Common Lisp with speed and readability in mind. Unlike other libraries, the code is not a pattern-matching-like, but a char-by-char procedural parser.

Common Lisp implementation of Graham Cormode and S. Muthukrishnan's Effective Computation of Biased Quantiles over Data Streams in ICDE’05.

This library implements the -> and ->> macros from Clojure, as well as several expansions on the idea.

(X)HTMLambda is yet another (X)HTML library which emphasizes programmability and user-friendliness. Each (X)HTML element is a structured object and pretty-printing of (X)HTML trees is well defined to provide properly indented human-readable output even for complex recursive arrangements.

This package ensures that special subclasses of standard-object cluster right in front of standard-object in the class precedence list.

This is a a Common Lisp re-implementation of the Rails routes system for mapping URLs.

Zippy is a library for the PKWARE Zip archive format. It can read and write zip files. It features:

• archive inspection without extraction;

• Zip64 support;

• split archive support;

• PKWARE decryption;

• fast deflate decompression thanks to 3bz;

• operates on streams and vectors;

• can compress stream->stream;

• extensible for other encryption and compression mechanisms.

This is a websocket server for Common Lisp using usockets to be portable between implementations and operating systems. It has a programming interface that allows for multiple websocket apps per server using Common Lisp keywords for different websocket events. It has useful restarts and customizable errors.

This package provides a Common Lisp library for defining OpenGL shader programs. There are also functions for referencing shader programs by name, querying for basic information about them, modifying uniform variables throughout the lifecycle of an OpenGL application, and managing certain OpenGL buffer object types (UBO, SSBO currently).

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

Hypergeometrica is a Common Lisp library for performing high-precision arithmetic, with a focus on performance. At the heart of it all are routines for multiplication. Hypergeometrica aims to support:

• In-core multiplication using various algorithms, from schoolbook to floating-point FFTs.

• In-core multiplication for large numbers using exact convolutions via number-theoretic transforms, which is enabled by 64-bit modular arithmetic.

• Out-of-core multiplication using derivatives of the original Cooley–Tukey algorithm.

On top of multiplication, one can build checkpointed algorithms for computing various classical constants, like \pi.

This package provides Common Lisp bindings for libev.

This package provides a robust CSV parser and printer that tries to follow the fine print of de facto standards. It can be configured to choose which standard exactly.

This library exports three symbols: with-raw-io, read-char, and read-line, to provide raw POSIX I/O in Common Lisp.

This package provides a SDL2 based vector graphic library for Common Lisp.

KMRCL is a collection of utilities used by a number of Kevin Rosenberg's Common Lisp packages.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.
