The Type-Templates library allows you to define types and “template functions” that can be expanded into various type-specialized versions to eliminate runtime dispatch overhead. It was specifically designed to implement low-level numerical data types and functionality.

Scrape on-line documentation out of a running Lisp image.

Parse INI formatted files into a Common Lisp list structure.

GARBAGE-POOLS is Common Lisp re-implementation of the APR Pools for resource management.

This library contains a lexer for syntaxes that use shell-like rules for quoting and commenting. It is a port of the shlex module from Python’s standard library.

This package implements binary trees of various kinds, presenting a uniform interface to them all.

This package provides Common Lisp FFI bindings for libwayland, primarily for the mahogany window manager.

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

RTG-MATH provides a selection of the math routines most commonly needed for making realtime graphics in Lisp.

cl-inotify uses cl-cffi to provide a Common Lisp interface to the Linux inotify API.

Eclector is a portable Common Lisp reader that is highly customizable, can recover from errors and can return concrete syntax trees.

In contrast to many other reader implementations, eclector can recover from most errors in the input supplied to it and continue reading. This capability is realized as a restart.

It can also produce instances of the concrete syntax tree classes provided by the concrete syntax tree library.

trivial-garbage provides a portable API to finalizers, weak hash-tables and weak pointers on all major implementations of the Common Lisp programming language.

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".

This package provides some condition classes, functions and macros which may be useful when building slightly complex systems.

The cl-sqlite package is an interface to the SQLite embedded relational database engine.

Parse-Declarations is a Common Lisp library to help writing macros which establish bindings. To be semantically correct, such macros must take user declarations into account, as these may affect the bindings they establish. Yet the ANSI standard of Common Lisp does not provide any operators to work with declarations in a convenient, high-level way. This library provides such operators.

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

This library introduces fast generic functions, i.e. functions that behave just like regular generic functions, except that the can be sealed on certain domains. If the compiler can then statically detect that the arguments to a fast generic function fall within such a domain, it will perform a variety of optimizations.

RE is a small, portable, lightweight, and quick, regular expression library for Common Lisp. It is a non-recursive, backtracing VM.

trivial-download allows you to download files from the Internet from Common Lisp. It provides a progress bar.

This is a lisp implementation of the Open Sound Control protocol (or more accurately “data transport specification” or “encoding”). The code should be close to ANSI standard common lisp and provides self contained code for encoding and decoding of OSC data, messages, and bundles.

bt-semaphore is a semaphore implementation for use with bordeaux-threads.

This library provides a macroexpand-all function that calls the implementation specific equivalent.
