This library extends LOG4CL system in a few ways:

* It helps with configuration of multiple appenders and layouts. * Has a facility to catch context fields and to log them. * Has a macro to log unhandled errors. * Adds a layout to write messages as JSON, which is useful for production as makes easier to parse and process such logs. * Uses the appenders which are not disabled in case of some error which again, should be useful for production.

Parse-Declarations is a Common Lisp library to help writing macros which establish bindings. To be semantically correct, such macros must take user declarations into account, as these may affect the bindings they establish. Yet the ANSI standard of Common Lisp does not provide any operators to work with declarations in a convenient, high-level way. This library provides such operators.

Maiden is a collection of systems to help you build applications and libraries that interact with chat servers. It can help you build a chat bot, or a general chat client. It also offers a variety of parts that should make it much easier to write a client for a new chat protocol.

CL-HEAP provides various implementations of heap data structures (a binary heap and a Fibonacci heap) as well as an efficient priority queue.

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.

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

HTML parser/emitter for CommonDoc.

definitions-systems provides a simple unified extensible way of processing named definitions.

This package provides a configuration library that adds the ability for Lem to manage packages within the user configuration directory.

This package provides a standard way to canonicalize slot values.

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.

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.

This is a small Common Lisp library that finds an open port within a range.

simple-neural-network is a Common Lisp library for creating, training and using basic neural networks. The networks created by this library are feedforward neural networks trained using backpropagation.

Portability library for IEEE float features that are not covered by the Common Lisp standard.

This is a Common Lisp library providing RFC 3986 percent-encoding.

This is a simple extension to MODULARIZE that allows modules to define and trigger hooks, which other modules can hook on to.

NJSON aims to make it convenient for one to decode, encode, and process JSON data, in the minimum keystrokes/minutes possible.

NJSON is parser-independent, with existing Common Lisp JSON parsers being loadable as additional system. jzon is included by default, though. Conveniences that NJSON provides are:

• encode and decode as single entry points for JSON reading and writing, be it from streams/string/files, or from those.

• jget, jcopy, jkeys, and their aliases to manipulate the decoded objects' properties without the need to worry about the low-level details of how these values are decoded.

• jif, jwhen, jor, jand, and other macros mimicking Lisp ones, while using truth values of JSON-decoded data.

• jbind and jmatch macros to destructure and validate parsed JSON.

• njson/aliases package to nickname to j for all the forms conveniently accessible as j:get, j:copy, j:if etc.

FSet is a functional set-theoretic collections library for Common Lisp. Functional means that all update operations return a new collection rather than modifying an existing one in place. Set-theoretic means that collections may be nested arbitrarily with no additional programmer effort; for instance, sets may contain sets, maps may be keyed by sets, etc.

This library provides Glib, GIO and Gobject bindings for Common Lisp via Gobject Introspection.

This library provides a modern project skeleton generator. In contract with other generators, CL-Project generates one package per file and encourages unit testing by generating a system for unit testing, so you can begin writing unit tests as soon as the project is generated.

This Common Lisp package provides a regular expression engine.

Parseq (pronounced parsec) is a parsing library for common lisp. It can be used for parsing lisp's sequences types: strings, vectors (e.g. binary data) and lists. Furthermore, parseq is able to parse nested structures such as trees (e.g. lists of lists, lists of vectors, vectors of strings).

Parseq uses parsing expression grammars (PEG) that can be defined through a simple interface. Extensions to the standard parsing expressions are available. Parsing expressions can be parameterised and made context aware. Additionally, the definition of each parsing expression allows the arbitrary transformation of the parsing tree.

The library is inspired by Esrap and uses a very similar interface. No code is shared between the two projects, however. The features of Esrap are are mostly included in parseq and complemented with additional, orthogonal features. Any resemblance to esrap-liquid is merely coincidental.
