This package provides a Common Lisp ASDF system auto-loading extension.

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

This package provides CFFI bindings for the stb_vorbis audio library to Common Lisp.

Common Lisp library for channel-based concurrency. In a nutshell, you create various threads sequentially executing tasks you need done, and use channel objects to communicate and synchronize the state of these threads.

jsown is a high performance Common Lisp JSON parser. Its aim is to allow for the fast parsing of JSON objects in Common Lisp. Recently, functions and macros have been added to ease the burden of writing and editing jsown objects.

jsown allows you to parse JSON objects quickly to a modifiable Lisp list and write them back. If you only need partial retrieval of objects, jsown allows you to select the keys which you would like to see parsed. jsown also has a JSON writer and some helper methods to alter the JSON objects themselves.

Osicat is a lightweight operating system interface for Common Lisp on Unix-platforms. It is not a POSIX-style API, but rather a simple lispy accompaniment to the standard ANSI facilities.

Clavier is a general purpose validation library for Common Lisp.

This is a Common Lisp library to build and compose SXQL queries dynamically.

A small collection of common lisp macros to make collecting values easier.

The NUMPY-FILE-FORMAT library is a Common Lisp library for reading and writing NumPy .npy and .npz files.

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 library is a universal interface to the operating system package manager. It has extensive support for Guix, among others:

• package listing and searching;

• package installation and uninstallation;

• package file listing;

• profile listing;

• manifest listing and installation;

• generation listing, switching and deletion.

CL(x) xembed protocol implementation

DIFF is a package for computing various forms of differences between blobs of data and then doing neat things with those differences. Currently diff knows how to compute three common forms of differences: "unified" format diffs, "context" format diffs, and "vdelta" format binary diffs.

defclass-star provides defclass* and defcondition* to simplify class and condition declarations. Features include:

• Automatically export all or select slots at compile time.

• Define the :initarg and :accessor automatically.

• Specify a name transformer for both the :initarg and :accessor, etc.

• Specify the :initform as second slot value.

See https://common-lisp.net/project/defclass-star/configuration.lisp.html for an example.

Various ASDF extensions such as attached test and documentation system, explicit development support, etc.

This is a simple library to retrieve the argument list of a function.

CL-INTERPOL is a library for Common Lisp which modifies the reader so that you can have interpolation within strings similar to Perl or Unix Shell scripts. It also provides various ways to insert arbitrary characters into literal strings even if your editor/IDE doesn't support them.

BORDEAUX-THREADS is a proposed standard for a minimal MP/Threading interface. It is similar to the CLIM-SYS threading and lock support.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

This package provides functions to encode or decode byte vectors or byte streams using the Z85 format, which is a base-85 encoding used by ZeroMQ.

This is a purely math-related utility kit, providing functions which can be useful for games, 3D, and GL in general.

This is a library for quaternions. It contains most of the quaternion operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable. It also tries to be efficient where plausible. Each quaternion is made up of floats, which by default are single-floats, as they do not require value boxing on most modern systems and compilers.

3bz is an implementation of Deflate decompression (RFC 1951) optionally with zlib (RFC 1950) or gzip (RFC 1952) wrappers, with support for reading from foreign pointers (for use with mmap and similar, etc), and from CL octet vectors and streams.
