Coleslaw is a static site generator written in Common Lisp.

This is a trivial utility for distinguishing between a process running in a real terminal window and a process running in a dumb one, e.g. emacs-slime.

clsql is a Common Lisp interface to SQL RDBMS based on the Xanalys CommonSQL interface for Lispworks. It provides low-level database interfaces as well as a functional and an object oriented interface.

This package provides the LOCAL-TIME extensions for the cl-postgres ASDF system of postmodern.

Max’s Parser Combinators is a simple and pragmatic library for writing parsers and lexers based on combinatory parsing. MaxPC is capable of parsing deterministic, context-free languages, provides powerful tools for parse tree transformation and error handling, and can operate on sequences and streams. It supports unlimited backtracking, but does not implement Packrat Parsing. Instead, MaxPC achieves good performance through its optimized primitives, and explicit separation of matching and capturing input. In practice, MaxPC parsers perform better on typical computer languages—when compared to Packrat parsers—at the expense of not producing linear-time parsers.

This package provides a Common Lisp system implementing event bus.

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

The Bordeaux-FFT library provides a reasonably efficient implementation of the Fast Fourier Transform and its inverse for complex-valued inputs, in portable Common Lisp.

This Common Lisp library focuses on the small set of basic color manipulations (lightening, compliments, etc.) you might use to generate a color palette for a GUI or web page.

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

trivial-clipboard gives access to the system clipboard.

simple-routes is a simple Common Lisp RESTful routing facility on top of Hunchentoot.

This package contains an implementation of RFC 2388, which is used to process form data posted with HTTP POST method using enctype "multipart/form-data".

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 contains a few utility functions from the LispWorks library that are used in software such as ContextL.

This is a Common Lisp library to read and write disk-based file archives such as those generated by the tar and cpio programs on Unix.

This is a Common Lisp library providing various utilities.

This package provides a SDL2 based vector graphic library for Common Lisp.

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

Duologue is high-level interaction library for Common Lisp. It features coloured printing via cl-ansi-text and readline completion.

This package provides a Language Server Protocol implementation for use with the Alive Visual Studio Code extension.

It can be used in Emacs like this:

(require 'lsp)
(defun lsp-lisp-alive-start-ls ()
 "Start the alive-lsp."
 (interactive)
 (when-let (((lsp--port-available "localhost" lsp-lisp-alive-port)))
  (lsp-async-start-process #'ignore #'ignore
   "sbcl"
   "--eval"
   "(require :asdf)"
   "--eval"
   "(asdf:load-system :alive-lsp)"
   "--eval"
   (format "(alive/server::start :port %s)"
    lsp-lisp-alive-port))))

This Common Lisp library provides an implementation of in-memory input streams, output streams and io streams for any type of elements.

This package provides a collection of types, functions and macros. Some of the functionality is implemented from Graham's On Lisp and Seibel's Practical Common Lisp.

iterate is an iteration construct for Common Lisp. It is similar to the CL:LOOP macro, with these distinguishing marks:

• it is extensible,

• it helps editors like Emacs indent iterate forms by having a more lisp-like syntax, and

• it isn't part of the ANSI standard for Common Lisp.
