This is a system to help you easily and quickly deploy standalone common lisp applications as binaries. Specifically it is geared towards applications with foreign library dependencies that run some kind of GUI.

This is an implementation of the Unicode Standards Annex #14 (http://www.unicode.org/reports/tr14/) line breaking algorithm. It provides a fast and convenient way to determine line breaking opportunities in text.

Note that this algorithm does not support break opportunities that require morphological analysis. In order to handle such cases, please consult a system that provides this kind of capability, such as a hyphenation algorithm.

Also note that this system is completely unaware of layouting decisions. Any kind of layouting decisions, such as which breaks to pick, how to space between words, how to handle bidirectionality, and what to do in emergency situations when there are no breaks on an overfull line are left up to the user.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and MGRS.

This package defines a simple extensible protocol for computing a guess using advisors.

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

This library provides GTK4 bindings for Common Lisp via Gobject Introspection, in the cl-gtk4 ASDF system.

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.

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.

Feeder is a syndication feed library. It presents a general protocol for representation of feed items, as well as a framework to translate these objects from and to external formats. It also implements the RSS 2.0 and Atom formats within this framework.

Quickproject provides a quick way to make a Common Lisp project. After creating a project, it extends the ASDF registry so the project may be immediately loaded.

It can sometimes be useful to be able to parse chemical compounds in a user-friendly syntax into easy-to-manipulate s-expressions. You also want to be able to go in reverse. You could probably write your own parser — or you could just install the chemical-compounds package.

cl-syslog is a Common Lisp library that provides access to the syslog logging facility.

IOlib is to be a better and more modern I/O library than the standard Common Lisp library. It contains a socket library, a DNS resolver, an I/O multiplexer(which supports select(2), epoll(4) and kqueue(2)), a pathname library and file-system utilities.

This package provides a recursive-descent parser DSL for Common Lisp. It's intended as a simpler alternative to parser generators.

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.

string-case is a Common Lisp macro that generates specialised decision trees to dispatch on string equality.

BOOST-JSON is a simple JSON parsing library for Common Lisp.

The Babel library solves a similar problem while understanding more encodings. Trivial UTF-8 was written before Babel existed, but for new projects you might be better off going with Babel. The one plus that Trivial UTF-8 has is that it doesn't depend on any other libraries.

Vernacular is a build and module system for languages that compile to Common Lisp. It allows languages to compile to Lisp while remaining part of the Common Lisp ecosystem. Vernacular languages interoperate with Common Lisp and one another.

Vernacular handles locating files, compiling files into FASLs, tracking dependencies and rebuilding, and export and import between your new language, Lisp, and any other language Vernacular supports.

Vernacular builds on Overlord and is inspired by Racket.

This library implements efficient algorithms that calculate various string metrics in Common Lisp:

• Damerau-Levenshtein distance

• Hamming distance

• Jaccard similarity coefficient

• Jaro distance

• Jaro-Winkler distance

• Levenshtein distance

• Normalized Damerau-Levenshtein distance

• Normalized Levenshtein distance

• Overlap coefficient

This is a packrat parser for Common Lisp. In addition to regular Packrat / Parsing Grammar / TDPL features ESRAP supports:

• dynamic redefinition of nonterminals

• inline grammars

• semantic predicates

• introspective facilities (describing grammars, tracing, setting breaks)

• left-recursive grammars

• functions as terminals

• accurate, customizable parse error reports

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

This Common Lisp package offers functions for parsing and formatting decimal numbers. The package's main interface are the functions parse-decimal-number and format-decimal-number. The former is for parsing strings for decimal numbers and the latter for pretty-printing them as strings.

An implementation of the exponential backoff algorithm in Common Lisp. Inspired by the implementation found in Chromium. Read the header file to learn about each of the parameters.
