This a Common Lisp library to convert geographic coordinates between latitude/longitude and Open Location Code.

Germinal is a server for the Gemini protocol, written in Common Lisp.

Drakma is a full-featured HTTP client implemented in Common Lisp. It knows how to handle HTTP/1.1 chunking, persistent connections, re-usable sockets, SSL, continuable uploads, file uploads, cookies, and more.

Common Lisp ships with a set of powerful built in data structures including the venerable list, full featured arrays, and hash-tables. CL-containers enhances and builds on these structures by adding containers that are not available in native Lisp (for example: binary search trees, red-black trees, sparse arrays and so on), and by providing a standard interface so that they are simpler to use and so that changing design decisions becomes significantly easier.

CL-DATA-STRUCTURES is a Common Lisp library providing a portable collection of mutable and immutable data structures (dictionaries, sets, queues, sequences) and algorithms.

Moira is a library for monitoring and, if necessary, restarting long-running threads. In principle, it is like an in-Lisp process supervisor.

This library exports three symbols: with-raw-io, read-char, and read-line, to provide raw POSIX I/O in Common Lisp.

Command-Line-Args provides a main macro (command) that wraps a defun form and creates a new function that parses the command line arguments. It has support for command-line options, positional, and variadic arguments. It also generates a basic help message. The interface is meant to be easy and non-intrusive.

cl-dotenv is a utility library for loading .env files in Common Lisp.

This is a portability library that allows one to fully override the standard debugger provided by their Common Lisp system for situations where binding *debugger-hook* is not enough -- most notably, for break.

CL-FAST-ECS is a Common Lisp library providing an implementation of the ECS pattern, primarily focused on speed and interactive development.

ECS is an architectural data-oriented design pattern that allows for the effective processing of a large number of in-game objects while keeping the code and data separated. This provides flexibility in the way that game objects are built at runtime.

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

Radiance is a web application environment, which is sort of like a web framework, but more general, more flexible. It should let you write personal websites and generally deployable applications easily and in such a way that they can be used on practically any setup without having to undergo special adaptations.

simple-optimization is a Common Lisp library providing a function to solve unconstrained optimization problems numerically using either the gradient descent or a quasi-Newton method.

Convenient macros for common lambda patterns.

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

This package provides a standard interface to the various package lock implementations of Common Lisp.

This is an interface to the git binary to make controlling it from within Common Lisp much easier. It might not ever reach full coverage of all features given git's immense size, but features will be added as they are needed. The low-level command API is fully mapped however.

This package provides a canonical way of converting generalized booleans to booleans.

This an implementation of CDR 2: generic hash tables for Common Lisp

This is a small Common Lisp library that finds an open port within a range.

Html-entities is a Common Lisp library that lets you encode and decode entities in HTML.

This is a Common Lisp library to present tabular data in ascii-art tables.

This package provides Doug Hoyte's "Production" version of macros from the Let Over Lambda book, including community updates.
