Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

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.

Charje.documentation can used to parse Common Lisp docstrings the charje way, or it can be used to create custom docstring parsers. Docstring parsers are composed using mixin classes and initialization methods.

This package provides highly optimized base64 encoding and decoding. Besides conversion to and from strings, integer conversions are supported. Encoding with Uniform Resource Identifiers is supported by using a modified encoding table that uses only URI-compatible characters.

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.

cl-mssql provides an interface to connect to Microsoft SQL server. It uses the libsybdb foreign library provided by the FreeTDS project.

This library implements the let+ macro, which is a dectructuring extension of let*. It features:

• Clean, consistent syntax and small implementation (less than 300 LOC, not counting tests)

• Placeholder macros allow editor hints and syntax highlighting

• &ign for ignored values (in forms where that makes sense)

• Very easy to extend

A library for encoding text in various web-savvy encodings.

An implementation of the exponential backoff algorithm in Common Lisp. Inspired by the implementation found in Chromium. Read the header file to learn about each of the parameters.

cl-cookie is a Common Lisp library featuring parsing of cookie headers, cookie creation, cookie jar creation and more.

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

This package contains a few utility functions from the LispWorks library that are used in software such as ContextL.

This is a lisp implementation of the Open Sound Control protocol (or more accurately “data transport specification” or “encoding”). The code should be close to ANSI standard common lisp and provides self contained code for encoding and decoding of OSC data, messages, and bundles.

parse-number is a library of functions for parsing strings into one of the standard Common Lisp number types without using the reader. parse-number accepts an arbitrary string and attempts to parse the string into one of the standard Common Lisp number types, if possible, or else parse-number signals an error of type invalid-number.

CLML (Common Lisp Machine Learning) is a high performance and large scale statistical machine learning package

This package contains an implementation of RFC 2388, which is used to process form data posted with HTTP POST method using enctype "multipart/form-data".

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

This library lets you build a metaclass which in turn lets you specify extra slot options in its classes. Options may be easily inspected and custom inheritance may be set up. The Meta-Object Protocol (MOP) is used for the implementation - through closer-mop. Some convenience function for processing slot options are also available.

Possible use case: you want to automatically set up some definitions based on some slots, but you want to have control over it right in the class definition.

Cl-async is a library for general purpose, non-blocking programming in Common Lisp. It uses the libuv library as backend.

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

FLARE is a library designed to allow quick and precise particle effect creations. It does not concern itself with displaying and only with the management and movement of particles. As such, it can easily be integrated into any existing or future application.

This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

When dealing with network protocols and file formats, it's common to have to read or write 16-, 32-, or 64-bit datatypes in signed or unsigned flavors. Common Lisp sort of supports this by specifying :element-type for streams, but that facility is underspecified and there's nothing similar for read/write from octet vectors. What most people wind up doing is rolling their own small facility for their particular needs and calling it a day.

This library attempts to be comprehensive and centralize such facilities. Functions to read 16-, 32-, and 64-bit quantities from octet vectors in signed or unsigned flavors are provided; these functions are also SETFable. Since it's sometimes desirable to read/write directly from streams, functions for doing so are also provided. On some implementations, reading/writing IEEE singles/doubles (i.e. single-float and double-float) will also be supported.
