3D-VECTORS is a library for vector math in 3D space. It contains most of the vector operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable.

With lispy syntax, shortcuts, and improvements, LASS aims to help you out in writing CSS quick and easy. LASS was largely inspired by SASS. LASS supports two modes, one being directly in your lisp code, the other in pure LASS files.

HARMONY is a library that provides you with audio processing tools as well as an audio server to play back music, sfx, and so forth. It is most suited for use in a game engine, but may feasibly also be used for more advanced things such as a DAW

This package provides Common Lisp bindings to POSIX message queue, an IPC method that is easy to use and quick to setup.

This is a library to abstract away the parsing of Unix-style command-line arguments. Use it in conjunction with asdf:program-op or cl-launch for portable processing of command-line arguments.

This project is intended as a catchall for small, general-purpose extensions to Common Lisp. It contains:

• new-let, a macro that combines and generalizes let, let* and multiple-value-bind,

• gmap, an iteration macro that generalizes map.

This package provides Common Lisp bindings to the pango text layout library.

This package provides data frames for Common Lisp, a two-dimensional array-like structure in which each column contains values of one variable and each row contains one set of values from each column.

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.

High performance JSON encoder and decoder. Currently support: SBCL, CCL.

This is a Common Lisp library to make histograms using UTF-8 block characters.

This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.

This package provides a Common Lisp library for manipulating graphs and running graph algorithms.

This library is part of NUMCL. It provides a macro SPECIALIZED that performs a Julia-like dispatch on the arguments, lazily compiling a type-specific version of the function from the same code. The main target of this macro is speed.

This package provides support routines for the claw Common Lisp package.

SEEDABLE-RNG provides a convenient means of generating random numbers that are seedable with deterministic results across hardware and Common Lisp implementations.

This Common Lisp library interprets escape characters the same way that most other programming language do. It provides four readtables. The default one lets you write strings like this: #"This string has a newline in it!".

The LOCAL-TIME library is a Common Lisp library for the manipulation of dates and times. It is based almost entirely upon Erik Naggum's paper "The Long Painful History of Time".

This package implements an algorithm for the spelling of enharmonics and dealing with ties and dots in rhythm notation.

Domain specific language for producing TeX documents with Common Lisp.

This package provides CFFI bindings for Common Lisp to the Cairo C library.

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

This package holds an enhanced implementation of hooks (extension points). It works similarly to Emacs hooks with crucial improvements:

• If the compiler allows it (such as SBCL), type-checking is performed at compile-time and at run-time when adding handlers to a hook.

• On failure, multiple restarts are offered, such as disabling the offending handler or simply continuing to the next function.

• The hook handler execution order and combination can be customized.

• Anonymous functions (lambdas) can be added to hooks as handler objects. When inspecting hooks, readable names are thus exposed instead of lambda blackboxes. Handlers are compared through their names (through the mandatory name slot). A hook can not contain multiple handlers with the same name.

• A special provision is taken for “setters”, handlers that are meant to set a given place to a given values. Such handler objects can be compared and identified uniquely.

Helps writing concise CFFI-related code.
