LTK is a Common Lisp binding for the Tk graphics toolkit. It is written in pure Common Lisp and does not require any Tk knowledge for its usage.

A modern and consistent Common Lisp string manipulation library that focuses on modernity, simplicity and discoverability: (str:trim s) instead of (string-trim '(#\Space ...) s)), or str:concat strings instead of an unusual format construct; one discoverable library instead of many; consistency and composability, where s is always the last argument, which makes it easier to feed pipes and arrows.

A collection of Common Lisp utility functions and macros mostly not found in other utility packages.

This is a library that implements delimited continuations by transforming Common Lisp code to continuation passing style.

This package provides an implementation of the flexichain protocol, allowing client code to dynamically add elements to, and delete elements from a sequence (or chain) of such elements.

CL-STORE is a portable serialization package which should give you the ability to store all Common Lisp data types into streams.

Named readtables is a library that creates a namespace for named readtables, which is akin to package namespacing in Common Lisp.

Stealth-mixin is a Common Lisp library for creating stealth mixin classes. These are classes that are dynamically mixed into other classes without the latter being aware of it.

This is a Common Lisp library consisting of a collection of useful GPU shader functions, written with Shadow.

This package provides a trivial line-input library for VT-like terminals.

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

cl-inotify uses cl-cffi to provide a Common Lisp interface to the Linux inotify API.

cl-docutils is a Common Lisp implementation of the Docutils text processing system for processing plaintext into presentational formats such as HTML and LaTeX. It is based upon the Python Docutils reference implementation but uses Common Lisp idioms making it easier to extend and more flexible. As with the reference implementation it includes a parser for the reStructured text plaintext markup syntax which is suitable for marking up documentation and for use as user markup for collaborative web sites. It is successfully used to support a higher education peer-review assessment and online tutorial system.

Splits sequence into a list of subsequences delimited by objects satisfying the test.

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

This package provides a canonical way of converting class designators to classes.

LTK is a Common Lisp binding for the Tk graphics toolkit. It is written in pure Common Lisp and does not require any Tk knowledge for its usage.

Antik provides a foundation for scientific and engineering computation in Common Lisp. It is designed not only to facilitate numerical computations, but to permit the use of numerical computation libraries and the interchange of data and procedures, whether foreign (non-Lisp) or Lisp libraries. It is named after the Antikythera mechanism, one of the oldest examples of a scientific computer known.

This is a collection of useful helper modules and standard implementations for Radiance interfaces.

Simplified-Types is a library that provides functions for simplifying Common Lisp type specifiers. The API consists of two functions:

• simplify-type takes a type specifier and, optionally, an environment, and returns the corresponding simplified type.

• simplified-type-of takes an object and returns the simplified type of that object.

cl-alexandria-plus is a conservative set of extensions to cl-alexandria utilities.

For is a library for an extensible iteration macro. It allows you to write concise looping constructs similar to loop and iterate. Unlike loop however it is extensible and sensible, and unlike iterate it does not require code-walking and is easier to extend.

This is a Common Lisp library which provides functionality to read/write Bit Map Font (BMF) into text, JSON and XML.

This project is meant to provide tools for internationalizing Common Lisp programs.

One important aspect of internationalization is of course the language used in error messages, documentation strings, etc. But with this project we provide tools for all other aspects of internationalization as well, including dates, weight, temperature, names of physical quantities, etc.
