Skippy is a Common Lisp library to read and write GIF image files.

This library implements special functions and has a focus on high accuracy double-float calculations using the latest algorithms.

Dissect is a small Common Lisp library for introspecting the call stack and active restarts.

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.

Just wrap your Common Lisp function in this macro call and it will be optimized for tail recursion. You will be warned if the function is not tail recursive.

This package is a simple date and time library.

BKNR.DATASTORE is an in-memory CLOS based database with transactions for Common Lisp.

This is a library to find system font files. It works on systems with FontConfig on Linux, BSD. It does not have any foreign dependencies that aren't already directly available on the system.

XSubseq provides functions to be able to handle "subseq"s more effieiently.

This library is a small interface to portable but nonstandard introspection of Common Lisp environments. It is intended to allow a bit more compile-time introspection of environments in Common Lisp.

Quite a bit of information is available at the time a macro or compiler-macro runs; inlining info, type declarations, that sort of thing. This information is all standard - any Common Lisp program can (declare (integer x)) and such.

This info ought to be accessible through the standard &environment parameters, but it is not. Several implementations keep the information for their own purposes but do not make it available to user programs, because there is no standard mechanism to do so.

This library uses implementation-specific hooks to make information available to users. This is currently supported on SBCL, CCL, and CMUCL. Other implementations have implementations of the functions that do as much as they can and/or provide reasonable defaults.

This library allows macro writers to provide better feedback to macro users when errors are signaled during macroexpansion. It uses the compiler's concept of a source-form to report where the error or warning is located.

EASY-ROUTES is yet another routes handling system on top of Hunchentoot. It's just glue code for Restas routing subsystem (CL-ROUTES).

It supports:

• dispatch based on HTTP method

• arguments extraction from the url path

• decorators

• URL generation from route names

This package provides EASY-ROUTES, EASY-ROUTES+DJULA and EASY-ROUTES+ERRORS systems.

SPECIALIZATION-STORE system provides a new kind of function, called a store function, whose behavior depends on the types of objects passed to the function.

This is a dead-simple, non validating, inline CSS generator for Common Lisp. Its goals are axiomatic syntax, simple implementation to support portability, and boilerplate reduction in CSS.

This package provides a Common Lisp library for dice rolling and working with dice-roll statistics.

Vom is a logging library for Common Lisp. It's goal is to be useful and small. It does not provide a lot of features as other loggers do, but has a small codebase that's easy to understand and use.

CL(x) xembed protocol implementation

This Common Lisp library implements object prevalence (see https://en.wikipedia.org/wiki/System_prevalence). It allows for (de)serializing to and from s-exps as well as XML. Serialization of arbitrary classes and cyclic data structures are supported.

CL-DEBUG provides a unified way to enable or disable debug-specific code. Debugging code can be enabled or disabled relative to program features denoted by either a symbol or a keyword.

dbi is a Common Lisp library providing a database independent interface for MySQL, PostgreSQL and SQLite.

Flute is an easily composable HTML5 generation library in Common Lisp.

This package implements a simple interface for using WebSockets via Common Lisp.

Simple library to create temporary directories.

Croatoan provides high-level Common Lisp CLOS bindings for the ncurses terminal library.
