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 library allows you to implement and enforce proper finalization of compile-time constructs while building Lisp source files.

It produces two systems: asdf-finalizers and list-of.

This library is a path strings manipulation library inspired by Python's os.path. All functionality from os.path is supported on major operation systems.

The philosophy behind is to use simple strings and "dumb" string manipulation functions to handle paths and filenames. Where possible the corresponding OS system functions are called.

QURI (pronounced "Q-ree") is yet another URI library for Common Lisp. It is intended to be a replacement of PURI.

Manual translation from C to Common Lisp of some random number generation functions from the GSL library.

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

CL-STORE is a portable serialization package which should give you the ability to store all Common Lisp data types into streams.

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

fare-utils is a small collection of utilities. It contains a lot of basic everyday functions and macros.

exit-hooks provides a portable way to automatically call some user-defined function when exiting Common Lisp (both quit from the REPL or a kill in a shell). Like atexit in C and Python or Java’s Runtime.addShutdownHook(). It currently supports SBCL, CCL, ECL, ABCL, Allegro CL, clisp and CMUCL. Before exit-hooks, there was no portable way of doing so and no staightforward way to use an exit hook on ABCL. It can be used for tasks like parmenantly save something when exiting Lisp.

This package provides a statistical computing environment for Common Lisp.

The Plump-SEXP library is a backend for Plump which can convert between S-expressions and the Plump DOM.

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

Fast-io is about improving performance to octet-vectors and octet streams (though primarily the former, while wrapping the latter).

This is a dead-simple, non validating, inline CSS generator for Common Lisp. Its goals are axiomatic syntax, simple implementation to support portability, and boilerplate reduction in CSS.

cl-gserver is a 'message passing' library / framework with actors similar to Erlang or Akka. It supports creating reactive systems for parallel computing and event based message handling.

bubble-operator-upwards is a function that bubbles an operator upwards in a form, demultiplexing all alternative branches by way of cartesian product.

This library provides arbitrary precision (floating point) real numbers in Common Lisp.

A heap-based priority queue whose first and foremost priority is speed.

CL-STORE is a portable serialization package which should give you the ability to store all Common Lisp data types into streams.

This is a packrat parser for Common Lisp. In addition to regular Packrat / Parsing Grammar / TDPL features ESRAP supports:

• dynamic redefinition of nonterminals

• inline grammars

• semantic predicates

• introspective facilities (describing grammars, tracing, setting breaks)

• left-recursive grammars

• functions as terminals

• accurate, customizable parse error reports

Stealth-mixin is a Common Lisp library for creating stealth mixin classes. These are classes that are dynamically mixed into other classes without the latter being aware of it.

This package provides a set of bindings and utilities for accessing the OpenGL (Mesa), GLU and GLUT (FreeGLUT) APIs using CFFI.

This is a reverse proxy server written in and configurable in Common Lisp. It supports WebSocket, HTTP, HTTPS, HTTP to HTTPS redirecting, port and host forwarding configuration using a real programming language, HTTP header and body manipulation (also using a real programming language).
