This library introduces fast generic functions, i.e. functions that behave just like regular generic functions, except that the can be sealed on certain domains. If the compiler can then statically detect that the arguments to a fast generic function fall within such a domain, it will perform a variety of optimizations.

It can sometimes be useful to be able to parse chemical compounds in a user-friendly syntax into easy-to-manipulate s-expressions. You also want to be able to go in reverse. You could probably write your own parser — or you could just install the chemical-compounds package.

This is a Common Lisp library to calculate std140 or std430 layouts for a glsl UBO/SSBO.

This is a Common Lisp library to enable simple message pipelines.

SPECIALIZATION-STORE system provides a new kind of function, called a store function, whose behavior depends on the types of objects passed to the function.

This is a terminfo database front end in Common Lisp. The package provides a method for determining which capabilities a terminal (e.g. "xterm") has and methods to compile or put commands to a stream.

This package provides a concise, intuitive and flexible macro for trivial lambdas that eschews explicit naming of parameter variables in favor of positional references, with support for a used or ignored &rest parameter and automatic declaration of ignored parameters when logical gaps are left in the positional references. Further convenience features are provided.

This package contains the specification of all functions and variables from GLSL as data.

This package provides a Common Lisp system implementing event bus.

hdf5-cffi is a CFFI wrapper for the HDF5 library.

Provides a simple way of directing output to a stream according to the concise and intuitive semantics of FORMAT's stream argument.

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.

This library is an extension of the Common Lisp Object System (CLOS) that allows a compiler to inline a generic function under certain conditions.

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

RTG-MATH provides a selection of the math routines most commonly needed for making realtime graphics in Lisp.

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

This library provides GTK4 bindings for Common Lisp via Gobject Introspection, in the cl-gtk4 ASDF system.

This library is an implementation of the Secure Hash Algorithm 3 (SHA-3), also known as Keccak. The implementation is constrained to messages with an integral number of octets,i.e. sub-byte length messages are not supported.

This library provides a simple multithreading worker mechanism.

This package provides a canonical way of converting generalized booleans to booleans.

Supertrace provides a superior Common Lisp trace functionality for debugging and profiling real world applications.

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!".

NJSON aims to make it convenient for one to decode, encode, and process JSON data, in the minimum keystrokes/minutes possible.

NJSON is parser-independent, with existing Common Lisp JSON parsers being loadable as additional system. jzon is included by default, though. Conveniences that NJSON provides are:

• encode and decode as single entry points for JSON reading and writing, be it from streams/string/files, or from those.

• jget, jcopy, jkeys, and their aliases to manipulate the decoded objects' properties without the need to worry about the low-level details of how these values are decoded.

• jif, jwhen, jor, jand, and other macros mimicking Lisp ones, while using truth values of JSON-decoded data.

• jbind and jmatch macros to destructure and validate parsed JSON.

• njson/aliases package to nickname to j for all the forms conveniently accessible as j:get, j:copy, j:if etc.

Retrospectiff is a common lisp library for reading and writing images in the TIFF (Tagged Image File Format) format.
