CL-octet-streams is a library implementing in-memory octet streams for Common Lisp. It was inspired by the trivial-octet-streams and cl-plumbing libraries.

This library is a redefinition of the standard Common Lisp package that includes a number of renames and shadows.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

VAS-STRING-METRICS provides the Jaro, Jaro-Winkler, Soerensen-Dice, Levenshtein, and normalized Levenshtein string distance/similarity metrics algorithms.

A heap-based priority queue whose first and foremost priority is speed.

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.

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".

McCLIM is an implementation of the Common Lisp Interface Manager specification, a toolkit for writing GUIs in Common Lisp.

Nsymbols extends the regular package API of ANSI CL with more operations, allowing one to list:

• package-symbols.

• package-variables.

• package-functions.

• package-generic-functions.

• package-macros.

• package-classes.

• package-structures.

• And other symbol types, given define-symbol-type for those.

Nsymbols can also find symbols by their name/matching symbol with resolve-symbol. All these operations are aware of symbol visibility in the given packages, due to a symbol-visibility function.

An additional nsymbols/star system has a set of functions mirroring the regular Nsymbols ones, but using closer-mop to provide better results and returning structured data instead of symbols.

This library provides almost the same code as used inside Quicklisp for drawning progress bars

This library provides a simple multithreading worker mechanism.

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 Common Lisp implementation of Base64 encoding and decoding. Base64 encoding is a technique to encode binary data in a portable, safe printable, 7-bit ASCII format.

The Babel library solves a similar problem while understanding more encodings. Trivial UTF-8 was written before Babel existed, but for new projects you might be better off going with Babel. The one plus that Trivial UTF-8 has is that it doesn't depend on any other libraries.

This package provides highly optimized base64 encoding and decoding. Besides conversion to and from strings, integer conversions are supported. Encoding with Uniform Resource Identifiers is supported by using a modified encoding table that uses only URI-compatible characters.

BORDEAUX-THREADS is a proposed standard for a minimal MP/Threading interface. It is similar to the CLIM-SYS threading and lock support.

string-case is a Common Lisp macro that generates specialised decision trees to dispatch on string equality.

Trivial-features ensures that *FEATURES* is consistent across multiple Common Lisp implementations.

This library provides two strata to access the POSIX shm API:

• the package posix-shm/ffi, a collection of slim bindings to the POSIX API

• the package posix-shm, a lispy wrapper around the FFI that integrates more closely to the features of Common Lisp, and provides a handful of utilities and macros

Features include:

• open, close, create, resize, change ownership of, change permissions of, and memory map to shared memory objects

• open-shm appears more like open from the standard library

• open-shm*, for creating anonymous shm objects

• with-open-shm, with-mmap and similar with- macros for safely accessing resources with dynamic extent

This package ensures that special subclasses of standard-object cluster right in front of standard-object in the class precedence list.

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

This package provides the getopt function to parse command-line options. The options are organized in valid options, other arguments and unknown arguments. Optional Lisp conditions for error situations are also defined.

With lispy syntax, shortcuts, and improvements, LASS aims to help you out in writing CSS quick and easy. LASS was largely inspired by SASS. LASS supports two modes, one being directly in your lisp code, the other in pure LASS files.

colorize is a Lisp library for syntax highlighting supporting the following languages: Common Lisp, Emacs Lisp, Scheme, Clojure, C, C++, Java, Python, Erlang, Haskell, Objective-C, Diff, Webkit.
