This package provides an implementation of the hash-set data structure. It has constant time lookup, insertion and deletion.

Cl-reexport makes a package reexport symbols which are external symbols in other Common Lisp packages. This functionality is intended to be used with (virtual) hierarchical packages.

This library provides a uniform API, as specified in Common Lisp the Language 2, for accessing information about variable and function bindings from implementation-defined lexical environment objects. All major Common Lisp implementations are supported, even those which don't support the CLTL2 environment access API.

This library provides purely functional dictionaries and sets in Common Lisp based on the hash array-mapped trie data structure.

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

This data structure can be used to store the history of visited paths or URLs with a file or web browser, in a way that no “forward” element is ever forgotten.

The history tree is “global” in the sense that multiple owners (e.g. tabs) can have overlapping histories. On top of that, an owner can spawn another one, starting from one of its nodes (typically when you open a URL in a new tab).

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.

fmt provides an alternative to the Common Lisp format function by utilizing s-expressions for formatting directives instead of control strings.

This is a simple library to retrieve the argument list of a function.

clingon is a command-line option parsing library for Common Lisp. Its features include:

• Support for subcommands

• Support for command aliases

• Support for short and long options

• Related options may be grouped into categories

• Short options may be collapsed into a single argument, as in -xyz

• Long options support the notations --long-opt arg and --long-opt=arg

• Automatic generation of help/usage information for commands and subcommands

• Out-of-the-box support for --version and --help

• Support for various kinds of options including string, integer, boolean, switch, enum, list, counter, filepath, etc.

• Subcommands can look up global options defined in parent commands

• Support for required options

• Options can be initialized via environment variables

• Single interface for creating options using CLINGON:MAKE-OPTION

• Generate documentation for your command-line application

• Support for pre-hook and post-hook actions for commands, which allow invoking functions before and after the respective handler of the command is executed

• Support for Bash and Zsh completions

• Extensibility, so if you don't find something you need you can extend it by developing a new option kind, or even a new mechanism for initializing options, e.g., by looking up an external key/value store

This is a Common Lisp library that implements the 9p network filesystem protocol.

This is a Common Lisp library to change the capitalization and spacing of a string or a symbol. It can convert to and from Lisp, english, underscore and camel-case rules.

Fast-io is about improving performance to octet-vectors and octet streams (though primarily the former, while wrapping the latter).

This package provides Common Lisp extension to the MOP to allow abstract, final and singleton classes.

A CLOS class that defines callable objects whose behavior is similar to closures but adds conveniences such as introspectability.

PRINTV is a "batteries-included" tracing and debug-logging macro for Common Lisp.

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

This package provides the CL-SVG Common Lisp system to produce Scalable Vector Graphics files.

This is a lightweight, non-consing, optimized queue implementation for Common Lisp.

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

This library is an extension of the Common Lisp Object System (CLOS) that allows a compiler to inline a generic function under certain conditions.

This package contains an implementation of RFC 2388, which is used to process form data posted with HTTP POST method using enctype "multipart/form-data".

RUTILS is a syntactic utilities package for Common Lisp.

These common lisp sources contain two variants of the Nelder-Mead algorithm. The original algorithm and a provably convergent, reliable variant by A. Bürmen et al, called the GRNMA.
