BOOST-JSON is a simple JSON parsing library for Common Lisp.

Hunchenissr works together with issr.js for the development of interactive (changing without page refreshes) websites making use of websocket and Common Lisp server HTML generation instead of mountains of convoluted Javascript.

cl-mysql is a Common Lisp implementation of a MySQL wrapper.

This package provides the LOCAL-TIME extensions for the cl-postgres ASDF system of postmodern.

This package provides a recursive-descent parser DSL for Common Lisp. It's intended as a simpler alternative to parser generators.

Common Lisp comes with quite some functions to compare objects for equality, yet none is applicable in every situation and in general this is hard, as equality of objects depends on the semantics of operations on them. As consequence, users find themselves regularly in a situation where they have to roll their own specialized equality test.

This module provides one of many possible equivalence relations between standard Common Lisp objects. However, it can be extended for new objects through a simple CLOS protocol. The rules when two objects are considered equivalent distinguish between mutating and frozen objects. A frozen object is promised not to be mutated in the future in a way that operations on it can notice the difference.

We have chosen to compare mutating objects only for identity (pointer equality), to avoid various problems. Equivalence for frozen objects on the other hand is established by recursing on the objects' constituent parts and checking their equivalence. Hence, two objects are equivalent under the OBJECT= relation, if they are either identical, or if they are frozen and structurally equivalent, i.e. their constituents are point-wise equivalent.

Since many objects are potentially mutable, but are not necessarily mutated from a certain point in their life time on, it is possible to promise to the equivalence relation that they remain frozen for the rest of their life time, thus enabling coarser equivalence than the often too fine-grained pointer equality.

binascii is a Common Lisp library for converting binary data to ASCII text of some kind. Such conversions are common in email protocols (for encoding attachments to support old non-8-bit clean transports) or encoding binary data in HTTP and XML applications. binascii supports the encodings described in RFC 4648: base64, base32, base16, and variants. It also supports base85, used in Adobe's PostScript and PDF document formats, and a variant called ascii85, used by git for binary diff files.

ALEXA is a tool similar to lex or flex for generating lexical analyzers. Unlike tools like lex, however, ALEXA defines a domain-specific language within your Lisp program, so you don't need to invoke a separate tool.

Markup allows the use of HTML syntax with in Common Lisp code. This has the advantage of being able to copy HTML snippets and have them instantly be functional, less double quotes than a s-expression approach, and designers will be able to understand the embedded HTML.

This library provides low-level libuv bindings for Common Lisp.

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

This is an implementation of a Markdown parser in Common Lisp.

This is a terminfo database front end in Common Lisp. The package provides a method for determining which capabilities a terminal (e.g. "xterm") has and methods to compile or put commands to a stream.

A utility for running external programs, built on UIOP. Cmd is designed to be natural to use, protect against shell interpolation and be usable from multi-threaded programs.

This package provides a Common Lisp wrapper system for the SDL 2.0 Mixer C Library.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.

This is an optimized Common Lisp library of Bob Jenkins' ISAAC-32 and ISAAC-64 algorithms, which are fast cryptographic random number generators: Indirection, Shift, Accumulate, Add, and Count.

Caveman is intended to be a collection of common parts for web applications. Caveman2 has three design goals:

• Be extensible.

• Be practical.

• Don't force anything.

This package provides a PEM (Privacy-Enhanced Mail) parser for Common Lisp.

This library provides trivial percent encoding and decoding functions for URLs.

This package provides a grab bag of miscellaneous Common Lisp utilities.

This library provides a WebSockets extension for the Huchentoot web server.

Quicksearch is a search-engine-interface for Common Lisp. The goal of Quicksearch is to find the Common Lisp library quickly. For example, if you will find the library about json, just type (qs:? 'json) at REPL.

The function quicksearch searches for Common Lisp projects in Quicklisp, Cliki, GitHub and BitBucket, then outputs results in REPL. The function ? is abbreviation wrapper for quicksearch.

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.
