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.

This Common Lisp library provides function to make QR codes and to save them as PNG files.

This package provides a priority queue implemented with an array-based heap.

This Common Lisp library provides a simple FIFO implementation with no external dependencies.

This package provides a standard interface to the various package lock implementations of Common Lisp.

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

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

This package provides a configuration library that adds the ability for Lem to manage packages within the user configuration directory.

This is a simple Common Lisp library to evaluate some forms in parallel.

Circular-Streams allows you to read streams circularly by wrapping real streams. Once you reach end-of-file of a stream, its file position will be reset to 0 and you're able to read it again.

This Common Lisp library provides utilities for the Bodge library collection.

Mito is yet another object relational mapper, and it aims to be a successor of Integral.

• Support MySQL, PostgreSQL and SQLite3.

• Add id (serial/uuid primary key), created_at and updated_at by default like Ruby's ActiveRecord.

• Migrations.

• Database schema versioning.

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.

Binary-types is a Common Lisp package for reading and writing binary files. Binary-types provides macros that are used to declare the mapping between Lisp objects and some binary (i.e. octet-based) representation.

This is a bindings and wrapper library to libmpg123 allowing for convenient, extensive, and fast decoding of MPEG1/2/3 (most prominently mp3) files.

This Common Lisp package offers functions for parsing and formatting decimal numbers. The package's main interface are the functions parse-decimal-number and format-decimal-number. The former is for parsing strings for decimal numbers and the latter for pretty-printing them as strings.

MT19937 is a portable Mersenne Twister pseudo-random number generator for Common Lisp.

This package provides a Common Lisp wrapper system for the SDL 2.0 C Library.

This package provides an ANSI CL adaptation of the SBCL mailbox utility.

This is a library that uses the other 3d-* math libraries to present an encapsulation for a spatial transformation. It offers convenience functions for operating on such transformations and for converting between them and the alternative 4x4 matrix representation.

This package provides GNU gettext completely implemented in Common Lisp without any C library bindings.

clsql is a Common Lisp interface to SQL RDBMS based on the Xanalys CommonSQL interface for Lispworks. It provides low-level database interfaces as well as a functional and an object oriented interface.

This package provides the getopt function to parse command-line options. The options are organized in valid options, other arguments and unknown arguments. Optional Lisp conditions for error situations are also defined.

From a string input and a list of candidates, return the most relevant candidates first.
