This package provides a Common Lisp system which wraps the BORDEAUX-THREADS system to be able to run things in the main thread of the implementation, for example drawing calls of GUI applications.

Infix-Math is a library that provides a special-purpose syntax for transcribing mathematical formulas into Lisp.

The Metering System is a portable Common Lisp code profiling tool. It gathers timing and consing statistics for specified functions while a program is running.

This package makes it possible to name classes by lists of symbols instead of symbols.

This is a utility library providing access to the mmap family of functions in a portable way. It allows you to directly map a file into the address space of your process without having to manually read it into memory sequentially. Typically this is much more efficient for files that are larger than a few Kb.

FARE-MOP is a small collection of utilities using the MetaObject Protocol. It notably contains a SIMPLE-PRINT-OBJECT method, and a SIMPLE-PRINT-OBJECT-MIXIN mixin that allow you to trivially define PRINT-OBJECT methods that print the interesting slots in your objects, which is great for REPL interaction and debugging.

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.

ContextL is a CLOS extension for Context-Oriented Programming (COP).

Find overview of ContextL's features in an overview paper: http://www.p-cos.net/documents/contextl-soa.pdf. See also this general overview article about COP which also contains some ContextL examples: http://www.jot.fm/issues/issue_2008_03/article4/.

ST-JSON (ST because it originated at Streamtech) is a Common Lisp library for encoding and decoding JSON values (as specified on json.org).

This library does mostly the same thing as CL-JSON, but is simpler and more precise about types (distinguishing boolean false, the empty array, and the empty object).

This package provide a Common Lisp library for .zip-file reading and writing.

Common Lisp port of Clojure's instaparse parser library - GLL parsing with EBNF/ABNF support.

CL-SYNTAX provides Reader Syntax Conventions for Common Lisp and SLIME.

This is a a Common Lisp re-implementation of the Rails routes system for mapping URLs.

This package provides functions to emit XML, with some complexity for handling indentation. It can be used to produce all sorts of useful XML output; it has an RSS 2.0 emitter built in, so you can make RSS feeds trivially.

This is a terminfo database front end in Common Lisp. The package provides a method for determining which capabilities a terminal (e.g. "xterm") has and methods to compile or put commands to a stream.

cl-numerical-utilities is a collection of packages useful in numerical applications, each big enough to be its own package, but too small to split out into a separate ASDF system.

In the crowded space of Common Lisp HTML generators, Spinneret occupies the following coordinates:

• Modern. Targets HTML5. Does not treat XML and HTML as the same problem. Assumes you will be serving your documents as UTF-8.

• Composable. Makes it easy to refactor HTML generation into separate functions and macros.

• Pretty. Treats HTML as a document format, not a serialization. Output is idiomatic and readable, following the coding style of the HTML5 specification.

• Aggressive. If something can be interpreted as HTML, then it will be, meaning that some Lisp forms can't be mixed with HTML syntax. In the trade-off between 90% convenience and 10% correctness Spinneret is on the side of convenience.

• Bilingual. Spinneret (after loading spinneret/ps) has the same semantics in Lisp and Parenscript.

Alexandria is a collection of portable utilities. It does not contain conceptual extensions to Common Lisp. It is conservative in scope, and portable between implementations.

This package provides a canonical way of converting class designators to classes.

Dexador is yet another HTTP client for Common Lisp with neat APIs and connection-pooling. It is meant to supersede Drakma.

QMyND, the QITAB MySQL Native Driver, is a MySQL client library that directly talks to a MySQL server in its native network protocol.

It's a part of QITAB umbrella project.

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

The cl-sqlite package is an interface to the SQLite embedded relational database engine.

This package provides an embedded template engine for Common Lisp.
