3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

This piece of code sets up some reader macros that make it simpler to input string literals which contain backslashes and double quotes This is very useful for writing complicated docstrings and, as it turns out, writing code that contains string literals that contain code themselves.

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

CXML implements a namespace-aware, validating XML 1.0 parser as well as the DOM Level 2 Core interfaces. Two parser interfaces are offered, one SAX-like, the other similar to StAX.

CL-SXML implements Oleg Kiselyov’s SXML, an S-expression-based rendering of the XML Infoset.

This library provides an OS and implementation independent access to timeouts.

This package provides Common Lisp FFI bindings for libwayland, primarily for the mahogany window manager.

This package provides a JSON Pointer (RFC6901) implementation for Common Lisp. This library aims to be independent from any JSON libraries (as much as possible).

CL-LOG is a general purpose logging utility, loosely modelled in some respects after Gary King's Log5. Its features include: logging to several destinations at once, via "messengers", each messenger is tailored to accept some log messages and reject others, and this tailoring can be changed on-the-fly, very rapid processing of messages which are rejected by all messengers, fully independent use of the utility by several different sub-systems in an application, support for messengers which cl:format text to a stream, support for messengers which do not invoke cl:format, timestamps in theory accurate to internal-time-units-per-second.

This package provides a Common Lisp library for dice rolling and working with dice-roll statistics.

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

DIFF is a package for computing various forms of differences between blobs of data and then doing neat things with those differences. Currently diff knows how to compute three common forms of differences: "unified" format diffs, "context" format diffs, and "vdelta" format binary diffs.

Just wrap your Common Lisp function in this macro call and it will be optimized for tail recursion. You will be warned if the function is not tail recursive.

THE-COST-OF-NOTHING is a library for measuring the run time of Common Lisp code. It provides macros and functions for accurate benchmarking and lightweight monitoring. Furthermore, it provides predefined benchmarks to determine the cost of certain actions on a given platform and implementation.

It's very basic implementation of channels and queue for Common Lisp.

The GRAPH Common Lisp library provides a data structures to represent graphs, as well as some graph manipulation and analysis algorithms (shortest path, maximum flow, minimum spanning tree, etc.).

Framework for representing and manipulating documents.

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

Pileup is a portable, performant, and thread-safe binary heap for Common Lisp.

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 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.

This package provides support routines for the claw Common Lisp package.

This is a Common Lisp library for simplifying packaging and loading of compiled foreign library collection.

(X)HTMLambda is yet another (X)HTML library which emphasizes programmability and user-friendliness. Each (X)HTML element is a structured object and pretty-printing of (X)HTML trees is well defined to provide properly indented human-readable output even for complex recursive arrangements.
