Markup allows the use of HTML syntax with in Common Lisp code. This has the advantage of being able to copy HTML snippets and have them instantly be functional, less double quotes than a s-expression approach, and designers will be able to understand the embedded HTML.

ContextL is a CLOS extension for Context-Oriented Programming (COP).

Find overview of ContextL's features in an overview paper: http://www.p-cos.net/documents/contextl-soa.pdf. See also this general overview article about COP which also contains some ContextL examples: http://www.jot.fm/issues/issue_2008_03/article4/.

cl-cffi-gtk is a Lisp binding to GTK+ 3 (GIMP Toolkit) which is a library for creating graphical user interfaces.

NFiles is a Common Lisp library to help manage file persistence and loading, in particular user-centric files like configuration files. It boasts the following features:

• Dynamic and customizable path expansion.

• Extensible serialization and deserialization.

• Cached reads and writes. When a file object expands to the same path as another one, a read or write on it won’t do anything in case there was no change since last write.

• (Experimental!) On-the-fly PGP encryption.

• Profile support.

• On read error, existing files are backed up.

• On write error, no file is written to disk, the existing file is preserved.

This package provides CFFI bindings and interface to Allegro 5 game developing library for Common Lisp.

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.

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

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

There are plenty of Lisp Markup Languages out there - every Lisp programmer seems to write at least one during his career - and CL-WHO (where WHO means "with-html-output" for want of a better acronym) is probably just as good or bad as the next one.

This package provides a Common Lisp wrapper system for the SDL 2.0 Mixer C Library.

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

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.

cl-num-utils implements simple numerical functions for Common Lisp, including:

• num=, a comparison operator for floats

• simple arithmeric functions, like sum and l2norm

• elementwise operations for arrays

• intervals

• special matrices and shorthand for their input

• sample statistics

• Chebyshev polynomials

• univariate rootfinding

DEFLATE data, defined in RFC1951, forms the core of popular compression formats such as zlib (RFC 1950) and gzip (RFC 1952). As such, Chipz also provides for decompressing data in those formats as well. BZIP2 is the format used by the popular compression tool bzip2.

With static-vectors, you can create vectors allocated in static memory.

FXML is a secure-by-default, error-recovering XML parser and serializer. It is a fork of CXML.

You should use FXML instead of CXML if:

• You are parsing potentially ill-formed XML.

• You are parsing potentially malicious XML.

• You need to use Klacks with namespaces.

FXML’s API is very close to CXML's, and for the most part you can refer to the CXML documentation for usage.

This package extends the Common Lisp reader syntax such that is accepts Org files as Lisp source code files.

Wayflan is a from-scratch Wayland communication library for Common Lisp. It makes a good-faith effort to mimic libwayland behavior not defined in the Wayland spec, to keep compatibility between the two libraries.

Wayflan is not a compositor nor a GUI toolkit. Its purpose is to parse Wayland protocol XML documents and exchange Wayland messages between other processes.

Features:

• Client support

• All implementation done in Common Lisp from the socket up

• Enum values are translated into keywords

• Wayland protocol introspection

• ASDF component :wayflan-client-impl generates code from XML. ASDF's extensible components make it possible to teach your program new protocols for Wayland without the need of a special build system.

This is a general Freetype 2 wrapper for Common Lisp using CFFI. It's geared toward both using Freetype directly by providing a simplified API, as well as providing access to the underlying C structures and functions for use with other libraries which may also use Freetype.

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

This package provides a framework to unify arbitrary Common Lisp objects while constructing bindings for placeholders (unification variables) in a template sublanguage.

Support library for numcl. Registers a function as an additional form that is considered as a candidate for a constant.

cl-gserver is a 'message passing' library / framework with actors similar to Erlang or Akka. It supports creating reactive systems for parallel computing and event based message handling.
