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.

Enables fast and convenient interoperation with foreign objects.

TRIVIAL-OCTET-STREAMS is a Common Lisp library implementing in-memory octet streams analogous to string streams.

CL-DOT is a Common Lisp library for generating Graphviz dot output from arbitrary Lisp data.

This library is a little experiment in reducing verbosity in Common Lisp, inspired by BODOL (https://github.com/bodil/BODOL).

Overlord is a build system in Common Lisp. It is a real build system, with all the modern features: rules with multiple outputs, parallel builds, immunity to clock issues, and dynamic dependencies.

But Overlord is more than another build system. Overlord is a uniform approach to dependencies inside or outside of a Lisp image. Overlord is to Make what Lisp macros are to C macros.

Overlord is designed to be used from the Lisp REPL. A command line interface is available in a separate repository. See https://github.com/ruricolist/overlord-cli.

This library provides two strata to access the POSIX shm API:

• the package posix-shm/ffi, a collection of slim bindings to the POSIX API

• the package posix-shm, a lispy wrapper around the FFI that integrates more closely to the features of Common Lisp, and provides a handful of utilities and macros

Features include:

• open, close, create, resize, change ownership of, change permissions of, and memory map to shared memory objects

• open-shm appears more like open from the standard library

• open-shm*, for creating anonymous shm objects

• with-open-shm, with-mmap and similar with- macros for safely accessing resources with dynamic extent

mito-auth provides a mito mixin class for user authorization.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

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

Parse-Declarations is a Common Lisp library to help writing macros which establish bindings. To be semantically correct, such macros must take user declarations into account, as these may affect the bindings they establish. Yet the ANSI standard of Common Lisp does not provide any operators to work with declarations in a convenient, high-level way. This library provides such operators.

Framework for representing and manipulating documents.

cl-draw-cons-tree draws a cons tree in ASCII-art style.

Hunchentoot is a web server written in Common Lisp and at the same time a toolkit for building dynamic websites. As a stand-alone web server, Hunchentoot is capable of HTTP/1.1 chunking (both directions), persistent connections (keep-alive), and SSL.

CEPL (Code Evaluate Play Loop ) is a lispy and REPL-friendly Common Lisp library for working with OpenGL.

Its definition of success is making the user feel that GPU programming has always been part of the languages standard.

The usual approach to using CEPL is to start it at the beginning of your Lisp session and leave it open for the duration of your work. You can then treat the window it creates as just another output for your graphics, analogous to how *standard-output* is treated for text.

This Common Lisp library focuses on the small set of basic color manipulations (lightening, compliments, etc.) you might use to generate a color palette for a GUI or web page.

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

Opticl is a Common Lisp library for representing, processing, loading, and saving 2-dimensional pixel-based images.

A client for the Stripe payment API.

System-Load is a Common Lisp library for accessing the system's CPU and memory usage.

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

This package provides a priority queue implemented with an array-based heap.

This package provides a JSON-RPC 2.0 server/client for Common Lisp.
