This package provides Common Lisp bindings to create OpenGL window and context manipulation code as well as system input handling. Direct FFI bindings to system functions are used so no third party C lib is required except system libraries.

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

This package provides a Common Lisp system implementing event bus.

Small library aiming to cut down time spent moving data between CLOS and JSON objects. It depends on YASON and it should be possible to use it alongside straight calls to functions from YASON.

trivial-garbage provides a portable API to finalizers, weak hash-tables and weak pointers on all major implementations of the Common Lisp programming language.

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

Ningle is a lightweight web application framework for Common Lisp.

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.

nontrivial-gray-streams is a compatibility system for Gray streams, which is an extension to Common Lisp that makes it possible to implement Common Lisp streams using generic functions.

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.

ZPB-TTF is a TrueType font file parser that provides an interface for reading typographic metrics, glyph outlines, and other information from the file.

Spatial-trees is a set of dynamic index data structures for spatially-extended data.

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.

This package extends the Common Lisp reader syntax such that is accepts Org files as Lisp source code files.

Croatoan provides high-level Common Lisp CLOS bindings for the ncurses terminal library.

Binary-types is a Common Lisp package for reading and writing binary files. Binary-types provides macros that are used to declare the mapping between Lisp objects and some binary (i.e. octet-based) representation.

Anaphora is the anaphoric macro collection from Hell: it includes many new fiends in addition to old friends like aif and awhen.

40ants-plantuml provides a wrapper around the PlantUML jar library.

Clavier is a general purpose validation library for Common Lisp.

This is a system to help you easily and quickly deploy standalone common lisp applications as binaries. Specifically it is geared towards applications with foreign library dependencies that run some kind of GUI.

This package contains a support library for other hu.dwim systems.

This package provides a standard interface to the various package lock implementations of Common Lisp.

Often times we need to destructure a form definition in a Common Lisp macro. This library provides a set of simple utilities to help with that.

Calispel is a Common Lisp library for thread-safe message-passing channels, in the style of the occam programming language, also known as communicating sequential processes (CSP). See https://en.wikipedia.org/wiki/Communicating_sequential_processes.

Calispel channels let one thread communicate with another, facilitating unidirectional communication of any Lisp object. Channels may be unbuffered, where a sender waits for a receiver (or vice versa) before either operation can continue, or channels may be buffered with flexible policy options.

Because sending and receiving on a channel may block, either operation can time out after a specified amount of time.

A syntax for alternation is provided (like ALT in occam, or Unix select()): given a sequence of operations, any or all of which may block, alternation selects the first operation that doesn't block and executes associated code. Alternation can also time out, executing an "otherwise" clause if no operation becomes available within a set amount of time.

Calispel is a message-passing library, and as such leaves the role of threading abstractions and utilities left to be filled by complementary libraries such as Bordeaux-Threads and Eager Future.
