Micros is a SLIME/SWANK implementation forked for use by the Lem editor.

This package provides a Common Lisp implementation of the semantic versioning specification: http://semver.org.

This is a library for access to atomic operation primitives such as compare-and-swap. It aims to be a rather thin layer over what the implementations offer.

On Cliki.net <http://www.cliki.net/Common%20Lisp%20Utilities>, there is a collection of Common Lisp Utilities, things that everybody writes since they're not part of the official standard. There are some very useful things there; the only problems are that they aren't implemented as well as you'd like (some aren't implemented at all) and they aren't conveniently packaged and maintained. It takes quite a bit of work to carefully implement utilities for common use, commented and documented, with error checking placed everywhere some dumb user might make a mistake.

Simple scheme to classify file types in a hierarchical fashion.

This library is intended to solve the problem of source tracking for Common Lisp code.

By "source tracking", it is meant that code elements that have a known origin in the form of a position in a file or in an editor buffer are associated with some kind of information about this origin.

Since the exact nature of such origin information depends on the Common Lisp implementation and the purpose of wanting to track that origin, the library does not impose a particular structure of this information. Instead, it provides utilities for manipulating source code in the form of what is called concrete syntax trees (CSTs for short) that preserve this information about the origin.

This package provides Common Lisp system collecting tools written to wrangle OpenGL Shader Language (GLSL) source files.

This package provides a Common Lisp web framework for building GUI applications. CLOG can take the place, or work along side, most cross platform GUI frameworks and website frameworks. The CLOG package starts up the connectivity to the browser or other websocket client (often a browser embedded in a native template application).

KMRCL is a collection of utilities used by a number of Kevin Rosenberg's Common Lisp packages.

Utility library for handling bit vectors, bit vector arithmetic, and universal integer type conversions between bit-vectors, byte-vectors, octals, decimals, and hexadecimal notation.

SLY is a fork of SLIME, an IDE backend for Common Lisp. It also features a completely redesigned REPL based on Emacs's own full-featured comint-mode, live code annotations, and a consistent interactive button interface. Everything can be copied to the REPL. One can create multiple inspectors with independent history.

Tripod is a Common Lisp web server aiming to ease plain text, HTML, and Gopher website hosting.

This is a Common Lisp wrapper for libjpeg-turbo library which provides TurboJPEG API for compressing and decompressing JPEG images.

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.

This package provides a shim between Python3 (specifically, the CPython implementation of Python) and Common Lisp.

This package provides a utility library intended at providing configurable reader macros for common tasks such as accessors, hash-tables, sets, uiop:run-program, arrays and a few others.

Tripod is a Common Lisp web server aiming to ease plain text, HTML, and Gopher website hosting.

This package provides a Common Lisp system with a collection of common tests and operations to help handling pathnames. It does not actually deal in handling the accessing of files on the underlying system however.

XSubseq provides functions to be able to handle "subseq"s more effieiently.

Vom is a logging library for Common Lisp. It's goal is to be useful and small. It does not provide a lot of features as other loggers do, but has a small codebase that's easy to understand and use.

cl-mysql is a Common Lisp implementation of a MySQL wrapper.

Conium is a portability library for debugger- and compiler-related tasks in Common Lisp. It is fork of SWANK-BACKEND.

Portable Threads (and Scheduled and Periodic Functions) API for Common Lisp (from GBBopen project).

This library validates superclasses according to a simple substitution model, thereby greatly simplifying the definition of class mixins.
