cl-mssql provides an interface to connect to Microsoft SQL server. It uses the libsybdb foreign library provided by the FreeTDS project.

Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to as CLIM and Iterate.

This library validates superclasses according to a simple substitution model, thereby greatly simplifying the definition of class mixins.

This system is an implementation of the Common Lisp type system; particularly cl:typep and cl:subtypep.

Various ASDF extensions such as attached test and documentation system, explicit development support, etc.

This library contains a collection of machine learning algorithms for online linear classification written in Common Lisp.

This is a Common Lisp implementation of the MessagePack (http://msgpack.org/) serialization/deserialization format, implemented according to http://wiki.msgpack.org/display/MSGPACK/Format+specification.

ASDF-FLV provides support for file-local variables through ASDF. A file-local variable behaves like *PACKAGE* and *READTABLE* with respect to LOAD and COMPILE-FILE: a new dynamic binding is created before processing the file, so that any modification to the variable becomes essentially file-local.

In order to make one or several variables file-local, use the macros SET-FILE-LOCAL-VARIABLE(S).

This library allows you to implement and enforce proper finalization of compile-time constructs while building Lisp source files.

It produces two systems: asdf-finalizers and list-of.

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.

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

This package provides an embedded template engine for Common Lisp.

ZPB-TTF is a TrueType font file parser that provides an interface for reading typographic metrics, glyph outlines, and other information from the file.

POLICY-COND provides tools to insert and execute code based on a compiler's OPTIMIZE policy. It also contains a contract-like notion of expectations, which allow dynamic checking or inclusion of various things that should happen depending on compiler policy.

This package provides a robust CSV parser and printer that tries to follow the fine print of de facto standards. It can be configured to choose which standard exactly.

A collection of Common Lisp utility functions and macros mostly not found in other utility packages.

This library allows you to define custom indentation hints for your macros if the one recognised by SLIME automatically produces unwanted results.

This package provides a simple yet powerful value inheritance scheme.

This package provides a CONSPACK implementation for Common Lisp.

This package provides Common Lisp system collecting tools written to wrangle OpenGL Shader Language (GLSL) source files.

FLARE is a library designed to allow quick and precise particle effect creations. It does not concern itself with displaying and only with the management and movement of particles. As such, it can easily be integrated into any existing or future application.

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.

fare-utils is a small collection of utilities. It contains a lot of basic everyday functions and macros.

This package provides Common Lisp FFI bindings for libwayland, primarily for the mahogany window manager.
