This package provides a priority queue implemented with an array-based heap.

Scrape on-line documentation out of a running Lisp image.

Transducers are an ergonomic and extremely memory-efficient way to process a data source. Data source refers to simple collections like lists or vectors, but also potentially large files or generators of infinite data.

cl-rmath is a simple, autogenerated foreign interface for the standalone R API libRmath. There has been no effort to provide a high-level interface for the original library, instead, this library is meant to serve as a building block for such an interface.

On Cliki.net <http://www.cliki.net/Common%20Lisp%20Utilities>, there is a collection of Common Lisp Utilities, things that everybody writes since they're not part of the official standard. There are some very useful things there; the only problems are that they aren't implemented as well as you'd like (some aren't implemented at all) and they aren't conveniently packaged and maintained. It takes quite a bit of work to carefully implement utilities for common use, commented and documented, with error checking placed everywhere some dumb user might make a mistake.

cl-smug is a library for parsing text, based on monadic parser combinators. Using a simple technique from the functional programming camp, cl-smug makes it simple to create quick extensible recursive descent parsers without funky syntax or impenetrable macrology.

Wu-Decimal enables convenient, arbitrary-precision decimal arithmetic through a reader macro, #$, and an update to the pprint dispatch table. Wu-Decimal uses the CL rational type to store decimals, which enables numeric functions such as +, -, etc., to operate on decimal numbers in a natural way.

nontrivial-gray-streams is a compatibility system for Gray streams, which is an extension to Common Lisp that makes it possible to implement Common Lisp streams using generic functions.

This is a native Common Lisp graphics math library with an emphasis on performance and correctness.

This package allows flexible specification of package-local preferences.

This package provides a client for SMTP.

This package provides a Common Lisp system implementing event bus.

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 library is intended to solve the problem of source tracking for Common Lisp code.

By "source tracking", it is meant that code elements that have a known origin in the form of a position in a file or in an editor buffer are associated with some kind of information about this origin.

Since the exact nature of such origin information depends on the Common Lisp implementation and the purpose of wanting to track that origin, the library does not impose a particular structure of this information. Instead, it provides utilities for manipulating source code in the form of what is called concrete syntax trees (CSTs for short) that preserve this information about the origin.

cl-template is a template engine for Common Lisp, taking inspiration from Ruby's ERb module.

This is a very short and simple program, written in Common Lisp, that extends Common Lisp to embed shell code in a manner similar to Perl's backtick. It has been forked from SHELISP.

Trial is a game engine written in Common Lisp. Unlike many other engines, it is meant to be more of a loose connection of components that can be fit together as required by any particular game.

This package is a list manipulation library for Common Lisp inspired by Haskell package Data.List.

This library can be used to display a progress bar on one line.

cl-cron is a simple tool that provides cron like facilities directly inside of Common Lisp.

A Common Lisp client library for Apache Kafka.

iterate is an iteration construct for Common Lisp. It is similar to the CL:LOOP macro, with these distinguishing marks:

• it is extensible,

• it helps editors like Emacs indent iterate forms by having a more lisp-like syntax, and

• it isn't part of the ANSI standard for Common Lisp.

This package provides a concise, intuitive and flexible macro for trivial lambdas that eschews explicit naming of parameter variables in favor of positional references, with support for a used or ignored &rest parameter and automatic declaration of ignored parameters when logical gaps are left in the positional references. Further convenience features are provided.

cl-alexandria-plus is a conservative set of extensions to cl-alexandria utilities.
