fast-websocket is an optimized low-level WebSocket protocol parser/composer.

CL-FTP is a library which provides FTP client functionality to a Common Lisp program. CL-FTP uses the USOCKET package for network sockets and the SPLIT-SEQUENCE package for some parsing needs.

Optima is a fast pattern matching library which uses optimizing techniques widely used in the functional programming world.

This package provides an ASN.1 encoder/decoder for Common Lisp.

This Common Lisp library provides an implementation of in-memory input streams, output streams and io streams for any type of elements.

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

This package provides a UTF-8 string input stream over a binary stream for Common Lisp.

QMyND, the QITAB MySQL Native Driver, is a MySQL client library that directly talks to a MySQL server in its native network protocol.

It's a part of QITAB umbrella project.

The main purpose of this n+2nd reimplementation of quasiquote is enable matching of quasiquoted patterns, using Optima or Trivia.

This package provides a Common Lisp library to work with the JSON file format.

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

With static-vectors, you can create vectors allocated in static memory.

jsown is a high performance Common Lisp JSON parser. Its aim is to allow for the fast parsing of JSON objects in Common Lisp. Recently, functions and macros have been added to ease the burden of writing and editing jsown objects.

jsown allows you to parse JSON objects quickly to a modifiable Lisp list and write them back. If you only need partial retrieval of objects, jsown allows you to select the keys which you would like to see parsed. jsown also has a JSON writer and some helper methods to alter the JSON objects themselves.

NASDF is an ASDF extension providing utilities to ease system setup, testing and installation.

• Simple way to fetch Git submodules and “do the right thing” for setup. This may effectively supersede Quicklisp. A benefit of using Git submodules over the default Quicklisp distribution is improved reproducibility.

• Test helpers, like distinction between offline and online tests, or continuous integration options, and warning reports.

• Installation helpers, for instance to install libraries, icons and desktop files to the right directories.

zsort is a collection of portable sorting algorithms. Common Lisp provides the sort and stable-sort functions but these can have different algorithms implemented according to each implementation. Also, the standard sorting functions might not be the best for a certain situations. This library aims to provide developers with more options.

doplus is an iteration macro for Common Lisp.

Parse-js is a Common Lisp package for parsing JavaScript (ECMAScript 3). It has basic support for ECMAScript 5.

RE is a small, portable, lightweight, and quick, regular expression library for Common Lisp. It is a non-recursive, backtracing VM.

The Common Lisp Application Directories (CLAD) library is a simple API collection that provides access to a set of standard Common Lisp folders on a per-application or per-library basis.

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.

Loop has a consistent interface unlike other looping abstractions and ANSI list operations. You can define your own efters and gatherers that integrate tightly into other operations. All operations are non-consing when possible.

Dissect is a small Common Lisp library for introspecting the call stack and active restarts.

This package provides a consolidation of Common Lisp statistics libraries.

Random-Sample is a library for reliably taking a random sample from a sequence.
