Pileup is a portable, performant, and thread-safe binary heap for Common Lisp.

This is a Common Lisp library providing a set of macros for generating lexical analyzers automatically. The lexers generated using cl-lex can be used with cl-yacc.

This library provides an asynchronous process execution mechanism for Common Lisp.

TRIVIAL-TYPES provides missing but important type definitions such as PROPER-LIST, ASSOCIATION-LIST, PROPERTY-LIST and TUPLE.

DATA-SIFT is a Common Lisp data validation and transformation library inspired by cl-data-format-validation and WTForms validators.

This package provides a macro commonly used in livecoding to enable continuing when errors are raised. Simply wrap around a chunk of code and it provides a restart called continue which ignores the error and carrys on from the end of the body.

This library allows you to open native file dialogs to open and save files. This is useful if you have an application that's primarily text based and would like a more convenient file selection utility, or if you are working with a UI toolkit that does not offer a way to access the native file dialogs directly.

This library contains a lexer for syntaxes that use shell-like rules for quoting and commenting. It is a port of the shlex module from Python’s standard library.

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.

This package provides a Common Lisp library for fetching and parsing RSS feeds data via HTTP. Currently, it supports RSS versions 0.90, 0.91, and 0.92 as well as RSS version 2.

Dynamic-Classes helps to ease the prototyping process by bringing dynamism to class definition.

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.

This library provides the FORMGREP function and related utilities which find top-level Lisp forms matching the regular expression corresponding to an operator name, returning the matched forms and the names of the files and the line numbers where they were found.

The 3D-Spaces library implements a number of spatial query data structures; structures that can answer spatial range queries for optimized lookup, particularly suited for games.

This package provides a general-purpose connection pooling library for Common Lisp.

This library provides a tiny Common Lisp wrapper around setlocale(3) and can be used in conjunction with other FFI wrappers like cl-charms.

Clip is an attempt at a templating library that allows you to write templates in a way that is both accessible to direct webdesign and flexible. The main idea is to incorporate transformation commands into an HTML file through tags and attributes. Clip is heavily dependent on Plump and lQuery.

CL-TYPESETTING is a cross-platform Common Lisp typesetting library for all kind of typesetting applications.

Chemboy is a Common Lisp program for doing basic chemistry calculations. This package provides the text-based interface for Chemboy.

Very basic library for dealing with CL's hash tables. The idea was spawned through working with enough JSON APIs and config files, causing a lot of headaches in the process.

Alloy is a user interface toolkit. It is defined through a set of protocols that allow for a clear interface, as well as a standardised way to integrate Alloy into a target backend.

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

This is a c2ffi-based wrapper generator for Common Lisp.

This is a library to provide cross-platform access to gamepads, joysticks, and other such HID devices.
