Envy is a configuration manager for various applications. Envy uses an environment variable to determine a configuration to use. This can separate configuration system from an implementation.

clsql is a Common Lisp interface to SQL RDBMS based on the Xanalys CommonSQL interface for Lispworks. It provides low-level database interfaces as well as a functional and an object oriented interface.

A Common Lisp library implementing a few different kinds of queues:

• Bounded and unbounded FIFO queues.

• Lossy bounded FIFO queues that drop elements when full.

• Unbounded random-order queues that use less memory than unbounded FIFO queues.

Additionally, a synchronization wrapper is provided to make any queue conforming to the jpl-queues API thread-safe for lightweight multithreading applications. (See Calispel for a more sophisticated CL multithreaded message-passing library with timeouts and alternation among several blockable channels.)

This system implements binding threading macros -- a kind of threading macros with different semantics than classical, Clojure core threading macros or their extension, swiss-arrows. Two Common Lisp implementations of those are arrows and arrow-macros.

This system is a fork of arrows with changes in semantics that make it impossible to merge back upstream.

Feeder is a syndication feed library. It presents a general protocol for representation of feed items, as well as a framework to translate these objects from and to external formats. It also implements the RSS 2.0 and Atom formats within this framework.

This package extends the Common Lisp reader syntax such that is accepts Org files as Lisp source code files.

This package provides an example implementation of the Common Lisp condition system and library, based on the original condition system implementation by Kent M. Pitman.

This library defines most Common Lisp standard macros that can be defined in a portable way and that can generate portable code. Some of these macros may not be good enough as the final version for a typical implementation, but they will work.

A library and command line utility to automatically indent Common Lisp source files.

CL-UNICODE is a portable Unicode library Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

This package provides Common Lisp bindings to the pango text layout library.

IOlib is to be a better and more modern I/O library than the standard Common Lisp library. It contains a socket library, a DNS resolver, an I/O multiplexer(which supports select(2), epoll(4) and kqueue(2)), a pathname library and file-system utilities.

This library implements the base58 encoding algorithm. It's basically base64 but with a smaller alphabet (58, as in the name) that doesn't include similar looking characters, among other things. See https://github.com/bitcoin/bitcoin/blob/master/src/base58.h for a full reference.

PAX provides an extremely poor man's Explorable Programming environment. Narrative primarily lives in so called sections that mix markdown docstrings with references to functions, variables, etc, all of which should probably have their own docstrings.

The primary focus is on making code easily explorable by using SLIME's M-. (slime-edit-definition). See how to enable some fanciness in Emacs Integration. Generating documentation from sections and all the referenced items in Markdown or HTML format is also implemented.

With the simplistic tools provided, one may accomplish similar effects as with Literate Programming, but documentation is generated from code, not vice versa and there is no support for chunking yet. Code is first, code must look pretty, documentation is code.

This package provides the terminal-size:size function to get the size of the terminal from Common Lisp.

S-XML is a simple XML parser implemented in Common Lisp. This XML parser implementation has the following features:

• It works (handling many common XML usages).

• It is very small (the core is about 700 lines of code, including comments and whitespace).

• It has a core API that is simple, efficient and pure functional, much like that from SSAX (see also http://ssax.sourceforge.net).

• It supports different DOM models: an XSML-based one, an LXML-based one and a classic xml-element struct based one.

• It is reasonably time and space efficient (internally avoiding garbage generatation as much as possible).

• It does support CDATA.

• It should support the same character sets as your Common Lisp implementation.

• It does support XML name spaces.

This XML parser implementation has the following limitations:

• It does not support any special tags (like processing instructions).

• It is not validating, even skips DTD's all together.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic).

This software provides an interface by which Common Lisp programs can access lexicographic data from WordNet.

CLAWK is an AWK implementation embedded into Common Lisp.

Trivial-features ensures that *FEATURES* is consistent across multiple Common Lisp implementations.

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.

qbase64 provides a fast and flexible base64 encoder and decoder for Common Lisp.

This library implements the base58 encoding algorithm. It's basically base64 but with a smaller alphabet (58, as in the name) that doesn't include similar looking characters, among other things. See https://github.com/bitcoin/bitcoin/blob/master/src/base58.h for a full reference.

This package provides a client for SMTP.
