CL-PPCRE is a portable regular expression library for Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

This is a purely math-related utility kit, providing functions which can be useful for games, 3D, and GL in general.

This library provides arbitrary precision (floating point) real numbers in Common Lisp.

This package provides a Common Lisp library for getting the battery information.

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 provides an automatic generator for ASDF's .asd files.

It's very basic implementation of channels and queue for Common Lisp.

This is a Common Lisp library for creating PNG images.

This Common Lisp package provides a regular expression engine.

concurrent-hash-tables is a Common Lisp portability library wrapping some implementations of concurrent hash tables which do not have to be entirely locked in their operation, including 42nd-at-threadmill, luckless, and a fallback, segmented hash table.

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

Library to fuzzily parse time and date strings into a universal-time timestamp.

This package provides CFFI bindings to the ASSIMP library for Common Lisp.

This Common Lisp library provides a tiny utility to change the size of a simple-array ensuring that the resulting array is still a simple-array.

Simple library to create temporary directories.

SQL generator for Common Lisp.

This project is intended as a catchall for small, general-purpose extensions to Common Lisp. It contains:

• new-let, a macro that combines and generalizes let, let* and multiple-value-bind,

• gmap, an iteration macro that generalizes map.

The Common Foreign Function Interface (CFFI) purports to be a portable foreign function interface for Common Lisp. The CFFI library is composed of a Lisp-implementation-specific backend in the CFFI-SYS package, and a portable frontend in the CFFI package.

SB-CGA is a computer graphics algebra library for Common Lisp.

Despite the prefix it is actually portable - but optimizations that make it fast (using SIMD instructions) are currently implemented for SBCL/x86-64 only.

This library lets you build a metaclass which in turn lets you specify extra slot options in its classes. Options may be easily inspected and custom inheritance may be set up. The Meta-Object Protocol (MOP) is used for the implementation - through closer-mop. Some convenience function for processing slot options are also available.

Possible use case: you want to automatically set up some definitions based on some slots, but you want to have control over it right in the class definition.

This library allows you to open native file dialogs to open and save files. This is useful if you have an application that's primarily text based and would like a more convenient file selection utility, or if you are working with a UI toolkit that does not offer a way to access the native file dialogs directly.

CL-MOUNT-INFO is a Common Lisp wrapper around getmntent(3) and related C functions to get information about the mounted file system.

A dataflow extension to Common Lisp that maintains a consistent state of cells according to functions specifying their relation.

This Common Lisp library provides a tiny utility to change the size of a simple-array ensuring that the resulting array is still a simple-array.
