This library provides a modern project skeleton generator. In contract with other generators, CL-Project generates one package per file and encourages unit testing by generating a system for unit testing, so you can begin writing unit tests as soon as the project is generated.

The py-configparser package implements the ConfigParser Python module functionality in Common Lisp. In short, it implements reading and writing of .INI-file style configuration files with sections containing key/value pairs of configuration options. In line with the functionalities in the python module, does this package implement basic interpolation of option values in other options.

Aims to be fast, modular, cachable and concise. It does so by defining each tag as a macro which expands to code printing the respective HTML source. Also employs a DSL for element attributes.

Splits sequence into a list of subsequences delimited by objects satisfying the test.

This library tries to provide a way to detect what kind of type the given predicate is trying to check. This is different from inferring the return type of a function.

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.

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

This package provides a UTF-8 string input stream over a binary stream for Common Lisp.

This is a YAML parser and emitter for Common Lisp built on top of libyaml.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

Static dispatch is a Common Lisp library, inspired by inlined-generic-function, which allows standard Common Lisp generic function dispatch to be performed statically (at compile time) rather than dynamically (runtime). This is similar to what is known as "overloading" in languages such as C++ and Java.

The purpose of static dispatch is to provide an optimization in cases where the usual dynamic dispatch is too slow, and the dynamic features of generic functions, such as adding/removing methods at runtime are not required. An example of such a case is a generic equality comparison function. Currently generic functions are considered far too slow to implement generic arithmetic and comparison operations when used heavily in numeric code.

This package provides CFFI bindings and interface to Allegro 5 game developing library for Common Lisp.

In Common Lisp, a special variable that is never dynamically bound typically serves as a stand-in for a global variable. The global-vars library provides true global variables that are implemented by some compilers. An attempt to rebind a global variable properly results in a compiler error. That is, a global variable cannot be dynamically bound.

Global variables therefore allow us to communicate an intended usage that differs from special variables. Global variables are also more efficient than special variables, especially in the presence of threads.

Hunchenissr works together with issr.js for the development of interactive (changing without page refreshes) websites making use of websocket and Common Lisp server HTML generation instead of mountains of convoluted Javascript.

Convenient macros for common lambda patterns.

This package provides a utility library intended at providing configurable reader macros for common tasks such as accessors, hash-tables, sets, uiop:run-program, arrays and a few others.

This is a task scheduling framework for Common Lisp.

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.

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

F2cl is a Common Lisp library that can convert Fortran 77 code into Common Lisp code.

This is a system for two dimensional computational geometry for Common Lisp.

Note: the system assumes exact rational arithmetic, so no floating point coordinates are allowed. This is not checked when creating geometric objects.

This Common Lisp library provides functions for Zstandard compression/decompression using bindings to the libzstd C library.

This a Common Lisp library to parse HTML5 documents.

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