lparallel is a library for parallel programming in Common Lisp, featuring:

• a simple model of task submission with receiving queue,

• constructs for expressing fine-grained parallelism,

• asynchronous condition handling across thread boundaries,

• parallel versions of map, reduce, sort, remove, and many others,

• promises, futures, and delayed evaluation constructs,

• computation trees for parallelizing interconnected tasks,

• bounded and unbounded FIFO queues,

• high and low priority tasks,

• task killing by category,

• integrated timeouts.

This package implements an algorithm for the spelling of enharmonics and dealing with ties and dots in rhythm notation.

Framework for representing and manipulating documents.

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.

Just wrap your Common Lisp function in this macro call and it will be optimized for tail recursion. You will be warned if the function is not tail recursive.

Calispel is a Common Lisp library for thread-safe message-passing channels, in the style of the occam programming language, also known as communicating sequential processes (CSP). See https://en.wikipedia.org/wiki/Communicating_sequential_processes.

Calispel channels let one thread communicate with another, facilitating unidirectional communication of any Lisp object. Channels may be unbuffered, where a sender waits for a receiver (or vice versa) before either operation can continue, or channels may be buffered with flexible policy options.

Because sending and receiving on a channel may block, either operation can time out after a specified amount of time.

A syntax for alternation is provided (like ALT in occam, or Unix select()): given a sequence of operations, any or all of which may block, alternation selects the first operation that doesn't block and executes associated code. Alternation can also time out, executing an "otherwise" clause if no operation becomes available within a set amount of time.

Calispel is a message-passing library, and as such leaves the role of threading abstractions and utilities left to be filled by complementary libraries such as Bordeaux-Threads and Eager Future.

Flute is an easily composable HTML5 generation library in Common Lisp.

The LOCAL-TIME library is a Common Lisp library for the manipulation of dates and times. It is based almost entirely upon Erik Naggum's paper "The Long Painful History of Time".

TRIVIAL-TYPES provides missing but important type definitions such as PROPER-LIST, ASSOCIATION-LIST, PROPERTY-LIST and TUPLE.

Alexandria is a collection of portable utilities. It does not contain conceptual extensions to Common Lisp. It is conservative in scope, and portable between implementations.

This package provides Common Lisp support for reading the Terragen .TER format. The format specification can be found at https://planetside.co.uk/wiki/index.php?title=Terragen_.TER_Format

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

Dissect is a small Common Lisp library for introspecting the call stack and active restarts.

This is a Common Lisp utilities library originating from the Zombie Raptor game engine project.

This library is a fork of SSL-CMUCL. The original SSL-CMUCL source code was written by Eric Marsden and includes contributions by Jochen Schmidt. Development into CL+SSL was done by David Lichteblau.

Static dispatch is a Common Lisp library, inspired by inlined-generic-function, which allows standard Common Lisp generic function dispatch to be performed statically (at compile time) rather than dynamically (runtime). This is similar to what is known as "overloading" in languages such as C++ and Java.

The purpose of static dispatch is to provide an optimization in cases where the usual dynamic dispatch is too slow, and the dynamic features of generic functions, such as adding/removing methods at runtime are not required. An example of such a case is a generic equality comparison function. Currently generic functions are considered far too slow to implement generic arithmetic and comparison operations when used heavily in numeric code.

ARNESI is Common Lisp utilities library similar to ALEXANDRIA, ANAPHORA or GOLDEN-UTILS.

This a Common Lisp library to parse HTML5 documents.

Cluster is an assembler (initially for x86 and x86-64) with a difference. To avoid the issue of defining a syntax, the input to Cluster is a list of standard objects (i.e., instances of the class STANDARD-OBJECT), as opposed to a character file or S-expressions.

This package provides a statistical computing environment for Common Lisp.

Very basic library for dealing with CL's hash tables. The idea was spawned through working with enough JSON APIs and config files, causing a lot of headaches in the process.

CL-PDF is a cross-platform Common Lisp library for generating PDF files.

This piece of code sets up some reader macros that make it simpler to input string literals which contain backslashes and double quotes This is very useful for writing complicated docstrings and, as it turns out, writing code that contains string literals that contain code themselves.
