jzon is a correct and safe JSON RFC 8259 parser for Common Lisp.

This is a lightweight, non-consing, optimized queue implementation for Common Lisp.

cl-css-lite is a library for generating CSS from an s-exp based syntax. When compiled with Parenscript loaded in the Lisp image, it also provides the same CSS generation facilities in Parenscript-generated JavaScript code.

This is a small Common Lisp library to make slugs, mainly for URIs, from English and beyond.

postmodern is a Common Lisp library for interacting with PostgreSQL databases. It provides the following features:

• Efficient communication with the database server without need for foreign libraries.

• Support for UTF-8 on Unicode-aware Lisp implementations.

• A syntax for mixing SQL and Lisp code.

• Convenient support for prepared statements and stored procedures.

• A metaclass for simple database-access objects.

This package produces 4 systems: postmodern, cl-postgres, s-sql, simple-date

SIMPLE-DATE is a very basic implementation of date and time objects, used to support storing and retrieving time-related SQL types. It is not loaded by default and you can use local-time (which has support for timezones) instead.

S-SQL is used to compile s-expressions to strings of SQL code, escaping any Lisp values inside, and doing as much as possible of the work at compile time.

CL-POSTGRES is the low-level library used for interfacing with a PostgreSQL server over a socket.

POSTMODERN itself is a wrapper around these packages and provides higher level functions, a very simple data access object that can be mapped directly to database tables and some convenient utilities. It then tries to put all these things together into a convenient programming interface

Ironclad is a cryptography library written entirely in Common Lisp. It includes support for several popular ciphers, digests, MACs and public key cryptography algorithms. For several implementations that support Gray streams, support is included for convenient stream wrappers.

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.

FARE-MOP is a small collection of utilities using the MetaObject Protocol. It notably contains a SIMPLE-PRINT-OBJECT method, and a SIMPLE-PRINT-OBJECT-MIXIN mixin that allow you to trivially define PRINT-OBJECT methods that print the interesting slots in your objects, which is great for REPL interaction and debugging.

This is a very simple color library for Common Lisp, providing

• Types for representing colors in HSV and RGB spaces.

• Simple conversion functions between the above types (and also hexadecimal representation for RGB).

• Some predefined colors (currently X11 color names – of course the library does not depend on X11).Because color in your terminal is nice.

This library is no longer supported by its author.

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 is a library for selecting portions of sequences, arrays or data-frames.

This package provides functions for generating lorem ipsum text.

This is a Common Lisp library that converts floating point values to IEEE 754 binary representation.

This package provides a hierarchy of major functions and auxiliary functions related to the structured analysis and processing of open text.

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

SB-CGA is a computer graphics algebra library for Common Lisp.

Despite the prefix it is actually portable - but optimizations that make it fast (using SIMD instructions) are currently implemented for SBCL/x86-64 only.

This is a small library to help you with managing the Common Lisp docstrings for your library.

Opticl is a Common Lisp library for representing, processing, loading, and saving 2-dimensional pixel-based images.

This is a Common Lisp library for creating PNG images.

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

This library can be used to print the licenses used by a Common Lisp project and its dependencies.

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

This is a Common Lisp library that converts floating point values to IEEE 754 binary representation.

This is a library to allow easy handling of external processes, and primarily to get their output. It handles proper copying of the standard and error outputs of the process simultaneously, both in a sequential and parallel fashion. It also features a lazy directory switching mechanism, to avoid running into parallelism problems when having to change directory.
