This library provides a uniform API, as specified in Common Lisp the Language 2, for accessing information about variable and function bindings from implementation-defined lexical environment objects. All major Common Lisp implementations are supported, even those which don't support the CLTL2 environment access API.

deeds allows for efficient event delivery to multiple handlers with a complex event filtering system.

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.

Binary-types is a Common Lisp package for reading and writing binary files. Binary-types provides macros that are used to declare the mapping between Lisp objects and some binary (i.e. octet-based) representation.

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 is a Common Lisp library which provides functionality to read/write Bit Map Font (BMF) into text, JSON and XML.

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.

cl-gserver is a 'message passing' library / framework with actors similar to Erlang or Akka. It supports creating reactive systems for parallel computing and event based message handling.

DAEMON provides the functionality of daemonizing Common Lisp processes on UNIX like platforms.

This package defines a Common Lisp package, :elements, with an ELEMENT structure and a number of functions to search the periodic table.

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.

Serapeum is a conservative library of Common Lisp utilities. It is a supplement, not a competitor, to Alexandria.

A mixture of features from eRuby and HTML::Template. You could name it "Yet Another LSP" (LispServer Pages) but it's a bit more than that and not limited to a certain server or text format.

This package provides CFFI binding to libmixed audio library for Common Lisp with support of other audio formats available on GNU/Linux systems:

• Alsa

• Jack

• Openmpt

• PulseAudio

• Flac (via CL-FLAC)

• Mpg123 (via CL-MPG123)

• Ogg/vorbis (via CL-VORBIS)

• Out123 (via CL-OUT123)

• WAV

Clack is a web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack.

CLAWK is an AWK implementation embedded into Common Lisp.

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

This is futures implementation for Common Lisp. It plugs in nicely to cl-async.

This package provides CFFI bindings to convert between different character encodings using iconv.

FLOW is a flowchart graph library. Unlike other graphing libraries, this one focuses on nodes in a graph having distinct ports through which connections to other nodes are formed. This helps in many concrete scenarios where it is important to distinguish not only which nodes are connected, but also how they are connected to each other.

Particularly, a lot of data flow and exchange problems can be reduced to such a flowchart. For example, an audio processing library may present its pipeline as a flowchart of segments that communicate with each other through audio sample buffers. Flow gives a convenient view onto this kind of problem, and even allows the generic visualisation of graphs in this format.

This system implements a general definitions introspection library. It gives you the ability to retrieve definitions or bindings associated with designators such as symbols, packages, and names in general. For instance, it allows you to retrieve all function, type, variable, method, etc. definitions of a symbol.

This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.

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.

Babel is a charset encoding and decoding library, not unlike GNU libiconv, but completely written in Common Lisp.
