MOP utilities provide a common interface between Lisps and make the MOP easier to use.

cl-numerical-utilities is a collection of packages useful in numerical applications, each big enough to be its own package, but too small to split out into a separate ASDF system.

This package provides CFFI bindings for Common Lisp to the Cairo C library.

This is a Common Lisp implementation of the Encoding for Robust Immutable Storage specification (ERIS).

This package provides an implementation of a base 16 builder for Common Lisp.

FXML is a secure-by-default, error-recovering XML parser and serializer. It is a fork of CXML.

You should use FXML instead of CXML if:

• You are parsing potentially ill-formed XML.

• You are parsing potentially malicious XML.

• You need to use Klacks with namespaces.

FXML’s API is very close to CXML's, and for the most part you can refer to the CXML documentation for usage.

This package provides an embedded template engine for Common Lisp.

This is a websocket server for Common Lisp using usockets to be portable between implementations and operating systems. It has a programming interface that allows for multiple websocket apps per server using Common Lisp keywords for different websocket events. It has useful restarts and customizable errors.

This is a Gettext-style internationalisation framework for Common Lisp.

CHRONICITY is Common Lisp natural language date and time parser inspired by Ruby's Chronic.

cl-irc is a Common Lisp IRC client library that features (partial) DCC, CTCP and all relevant commands from the IRC RFCs (RFC2810, RFC2811 and RFC2812).

Features:

• implements all commands in the RFCs

• extra convenience commands such as op/deop, ban, ignore, etc.

• partial DCC SEND/CHAT support

• event driven model with hooks makes interfacing easy

• the user can keep multiple connections

• all CTCP commands

Flexi-streams is an implementation of "virtual" bivalent streams that can be layered atop real binary or bivalent streams and that can be used to read and write character data in various single- or multi-octet encodings which can be changed on the fly. It also supplies in-memory binary streams which are similar to string streams.

This is a native Common Lisp graphics math library with an emphasis on performance and correctness.

A Common Lisp library for computing differences between sequences based on the Python difflib module.

A collection of Common Lisp utility functions and macros mostly not found in other utility packages.

This package contains the specification of all functions and variables from GLSL as data.

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.

repl-utilities is a set of utilities which ease life at the REPL. It includes three sorts of features: introspective procedures, miscellaneous utility functions, and, pulling them together, methods to conveniently keep these symbols and optionally additional symbols available in whichever package you switch to.

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.

Bind extends the idea of of let and destructing to provide a uniform syntax for all your accessor needs. It combines let, destructuring-bind, with-slots, with-accessors, structure editing, property or association-lists, and multiple-value-bind and a whole lot more into a single form.

Arrow-macros provides clojure-like arrow macros (ex. ->, ->>) and diamond wands in swiss-arrows.

Trivial-Benchmark runs a block of code many times and outputs some statistical data for it. On SBCL this includes the data from time, for all other implementations just the real-time and run-time data. However, you can extend the system by adding your own metrics to it, or even by adding additional statistical computeations.

ST-JSON (ST because it originated at Streamtech) is a Common Lisp library for encoding and decoding JSON values (as specified on json.org).

This library does mostly the same thing as CL-JSON, but is simpler and more precise about types (distinguishing boolean false, the empty array, and the empty object).

This library is intended to solve the problem of source tracking for Common Lisp code.

By "source tracking", it is meant that code elements that have a known origin in the form of a position in a file or in an editor buffer are associated with some kind of information about this origin.

Since the exact nature of such origin information depends on the Common Lisp implementation and the purpose of wanting to track that origin, the library does not impose a particular structure of this information. Instead, it provides utilities for manipulating source code in the form of what is called concrete syntax trees (CSTs for short) that preserve this information about the origin.
