This package provides functions to encode or decode byte vectors or byte streams using the Z85 format, which is a base-85 encoding used by ZeroMQ.

cl-pass is a password hashing and verification library.

This package provides a grab bag of miscellaneous Common Lisp utilities.

Closer to MOP is a compatibility layer that rectifies many of the absent or incorrect CLOS MOP features across a broad range of Common Lisp implementations.

This is a bare-bones Permuted Congruential Generator implementation in pure Common Lisp.

PP-TOML is a Common Lisp library for parsing strings in the TOML configuration file format. It implements only the 0.1.0 specification of TOML.

cl-tar-file is a Common Lisp library that allows reading from and writing to various tar archive formats. Currently supported are the POSIX ustar, PAX (ustar with a few new entry types), GNU, and v7 (very old) formats.

This library is rather low level and is focused exclusively on reading and writing physical tar file entries using streams. Therefore, it contains no functionality for automatically building archives from a set of files on the filesystem or writing the contents of a file to the filesystem. Additionally, there are no smarts that read multiple physical entries and combine them into a single logical entry (e.g., with PAX extended headers or GNU long link/path name support). For a higher-level library that reads and writes logical entries, and also includes filesystem integration, see cl-tar.

Osicat is a lightweight operating system interface for Common Lisp on Unix-platforms. It is not a POSIX-style API, but rather a simple lispy accompaniment to the standard ANSI facilities.

This package provides a Common Lisp bindings to glfw, an OpenGL application development library.

This is a Common Lisp library to make histograms using UTF-8 block characters.

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

CIEL is a ready-to-use collection of libraries providing: a binary, to run CIEL scripts; a simple full-featured REPL for the terminal; a Lisp library and a core image.

cl-json provides an encoder of Lisp objects to JSON format and a corresponding decoder of JSON data to Lisp objects. Both the encoder and the decoder are highly customizable; at the same time, the default settings ensure a very simple mode of operation, similar to that provided by yason or st-json.

A Common Lisp library for generating a human-readable diff of two HTML documents.

This package allows flexible specification of package-local preferences.

MOP utilities provide a common interface between Lisps and make the MOP easier to use.

A Common Lisp library for computing differences between sequences based on the Python difflib module.

This package ensures that special subclasses of standard-object cluster right in front of standard-object in the class precedence list.

This package provides a Common Lisp library for manipulating graphs and running graph algorithms.

The LOCAL-TIME library is a Common Lisp library for the manipulation of dates and times. It is based almost entirely upon Erik Naggum's paper "The Long Painful History of Time".

This package implements an algorithm for the spelling of enharmonics and dealing with ties and dots in rhythm notation.

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-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.

Cluffer is a library for representing the buffer of a text editor. As such, it defines a set of CLOS protocols for client code to interact with the buffer contents in various ways, and it supplies different implementations of those protocols for different purposes.
